How to exclude master Database - sql-server

I have created the following query which will get the data from all databases. when i execute the query i am getting error invalid column id. i have investigated and found the table tbl_table_A (example) is listed in master database and this table is not having column id. i have exlcluded this DB master but not sure why the query is still calling the master DB. kindly advise
Query :
CREATE TABLE ##tbl_data
(
[database_name] NVARCHAR(500),
id INT,
last_run DATETIME,
[next_run] DATETIME,
last_run_status NVARCHAR(500)
)
DECLARE #StartDate NVARCHAR(MAX)
DECLARE #EndDate NVARCHAR(MAX)
DECLARE #strSQL NVARCHAR(MAX)
SET #StartDate = '10-Dec-2019 00:12:59'
SET #EndDate = '10-Dec-2019 00:17:59'
SET #strSQL =
'
USE [?]
IF ''?'' <> ''master'' AND ''?'' <> ''model'' AND ''?'' <> ''msdb'' AND ''?'' <> ''tempdb''
BEGIN
IF OBJECT_ID(''tbl_table_A'') IS NULL
RETURN;
insert into ##tbl_data
SELECT ''?'', id,last_run,next_run,last_run_status
FROM dbo.tbl_table_A nolock
WHERE last_run between cast ('''+#StartDate+''' as Datetime2) and cast ('''+#EndDate+''' as Datetime2)
END'
EXEC dbo.sp_msforeachdb #strSQL
Select * from ##tbl_data
Drop table ##tbl_data

i have exlcluded this DB master but not sure why the query is still
calling the master DB
No, your code does not "call" master.
Here is your code where I use print instead of insert.
This way you can see what exactly db is checked and whether there is or there is not your table there:
declare #strSQL NVARCHAR(MAX)
SET #strSQL =
'
USE [?]
IF ''?'' <> ''master'' AND ''?'' <> ''model'' AND ''?'' <> ''msdb'' AND ''?'' <> ''tempdb''
BEGIN
print ''?''
IF OBJECT_ID(''tbl_table_A'') IS NULL
begin
print ''there is no table tbl_table_A''
print ''----------------''
RETURN;
end
print ''***** THERE IS table tbl_table_A *****''
print ''----------------''
END'
EXEC dbo.sp_msforeachdb #strSQL

I always like to take a different approach to these types of problems. For one, I really dislike cursors and you don't really need one here. Also, sp_msforeachdb is not only undocumented it has some problems. It will sometimes skip databases and nobody really seems to know why. Aaron Bertrand discusses this and provides a better alternative here. https://sqlblog.org/2010/12/29/a-more-reliable-and-more-flexible-sp_msforeachdb
I prefer to do something like below. There are no loops and won't run into weird behavior like skipping tables. It also does not require a global temp table which can have serious concurrency issues. This requires two dynamic sql statements. The first gets the list of databases with the table you want to find. Then we use that data to generate the dynamic sql statement against the list of database we want to search.
if OBJECT_ID('tempdb..#Databases') is not null
drop table #Databases
DECLARE #StartDate NVARCHAR(MAX)
, #EndDate NVARCHAR(MAX)
, #strSQL NVARCHAR(MAX)
SELECT #StartDate = '20191210 00:12:59'
, #EndDate = '20191210 00:17:59'
, #strSQL = ''
declare #TableName sysname = 'tbl_table_A'
select #strSQL = #strSQL + 'select ''' + d.name + ''' from ' + quotename(d.name) + '.sys.tables where name = ''' + #TableName + ''' union all '
from sys.databases d
select #strSQL = left(#strSQL, len(#strSql) - 10) --this removes the last union all
CREATE TABLE #Databases
(
DatabaseName sysname
)
--select #strSQL
insert #Databases
(
DatabaseName
)
exec sp_executesql #strSQL
set #strSQL = ''
select #strSQL = #strSQL + 'select ''' + d.DatabaseName + ''', id, last_run, next_run, last_run_status from ' + quotename(d.DatabaseName) + '.dbo.' + #TableName + ' where last_run between #_StartDate and #_EndDate union all '
from #Databases d
select #strSQL = left(#strSQL, len(#strSql) - 10)
--select #strSQL
exec sp_executesql #strSQL, N'#_StartDate datetime, #_EndDate datetime', #_StartDate = #StartDate, #_EndDate = #EndDate

SQL Server Table Parameter without defining fields [duplicate]

I am trying to execute this query:
declare #tablename varchar(50)
set #tablename = 'test'
select * from #tablename
This produces the following error:
Msg 1087, Level 16, State 1, Line 5
Must declare the table variable "#tablename".
What's the right way to have the table name populated dynamically?
For static queries, like the one in your question, table names and column names need to be static.
For dynamic queries, you should generate the full SQL dynamically, and use sp_executesql to execute it.
Here is an example of a script used to compare data between the same tables of different databases:
Static query:
SELECT * FROM [DB_ONE].[dbo].[ACTY]
EXCEPT
SELECT * FROM [DB_TWO].[dbo].[ACTY]
Since I want to easily change the name of table and schema, I have created this dynamic query:
declare #schema sysname;
declare #table sysname;
declare #query nvarchar(max);
set #schema = 'dbo'
set #table = 'ACTY'
set #query = '
SELECT * FROM [DB_ONE].' + QUOTENAME(#schema) + '.' + QUOTENAME(#table) + '
EXCEPT
SELECT * FROM [DB_TWO].' + QUOTENAME(#schema) + '.' + QUOTENAME(#table);
EXEC sp_executesql #query
Since dynamic queries have many details that need to be considered and they are hard to maintain, I recommend that you read: The curse and blessings of dynamic SQL
Change your last statement to this:
EXEC('SELECT * FROM ' + #tablename)
This is how I do mine in a stored procedure. The first block will declare the variable, and set the table name based on the current year and month name, in this case TEST_2012OCTOBER. I then check if it exists in the database already, and remove if it does. Then the next block will use a SELECT INTO statement to create the table and populate it with records from another table with parameters.
--DECLARE TABLE NAME VARIABLE DYNAMICALLY
DECLARE #table_name varchar(max)
SET #table_name =
(SELECT 'TEST_'
+ DATENAME(YEAR,GETDATE())
+ UPPER(DATENAME(MONTH,GETDATE())) )
--DROP THE TABLE IF IT ALREADY EXISTS
IF EXISTS(SELECT name
FROM sysobjects
WHERE name = #table_name AND xtype = 'U')
BEGIN
EXEC('drop table ' + #table_name)
END
--CREATES TABLE FROM DYNAMIC VARIABLE AND INSERTS ROWS FROM ANOTHER TABLE
EXEC('SELECT * INTO ' + #table_name + ' FROM dbo.MASTER WHERE STATUS_CD = ''A''')
Use:
CREATE PROCEDURE [dbo].[GetByName]
#TableName NVARCHAR(100)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE #sSQL nvarchar(500);
SELECT #sSQL = N'SELECT * FROM' + QUOTENAME(#TableName);
EXEC sp_executesql #sSQL
END
You can't use a table name for a variable. You'd have to do this instead:
DECLARE #sqlCommand varchar(1000)
SET #sqlCommand = 'SELECT * from yourtable'
EXEC (#sqlCommand)
You'll need to generate the SQL content dynamically:
declare #tablename varchar(50)
set #tablename = 'test'
declare #sql varchar(500)
set #sql = 'select * from ' + #tablename
exec (#sql)
Use sp_executesql to execute any SQL, e.g.
DECLARE #tbl sysname,
#sql nvarchar(4000),
#params nvarchar(4000),
#count int
DECLARE tblcur CURSOR STATIC LOCAL FOR
SELECT object_name(id) FROM syscolumns WHERE name = 'LastUpdated'
ORDER BY 1
OPEN tblcur
WHILE 1 = 1
BEGIN
FETCH tblcur INTO #tbl
IF ##fetch_status <> 0
BREAK
SELECT #sql =
N' SELECT #cnt = COUNT(*) FROM dbo.' + quotename(#tbl) +
N' WHERE LastUpdated BETWEEN #fromdate AND ' +
N' coalesce(#todate, ''99991231'')'
SELECT #params = N'#fromdate datetime, ' +
N'#todate datetime = NULL, ' +
N'#cnt int OUTPUT'
EXEC sp_executesql #sql, #params, '20060101', #cnt = #count OUTPUT
PRINT #tbl + ': ' + convert(varchar(10), #count) + ' modified rows.'
END
DEALLOCATE tblcur
You need to use the SQL Server dynamic SQL:
DECLARE #table NVARCHAR(128),
#sql NVARCHAR(MAX);
SET #table = N'tableName';
SET #sql = N'SELECT * FROM ' + #table;
Use EXEC to execute any SQL:
EXEC (#sql)
Use EXEC sp_executesql to execute any SQL:
EXEC sp_executesql #sql;
Use EXECUTE sp_executesql to execute any SQL:
EXECUTE sp_executesql #sql
Declare #tablename varchar(50)
set #tablename = 'Your table Name'
EXEC('select * from ' + #tablename)
Also, you can use this...
DECLARE #SeqID varchar(150);
DECLARE #TableName varchar(150);
SET #TableName = (Select TableName from Table);
SET #SeqID = 'SELECT NEXT VALUE FOR ' + #TableName + '_Data'
exec (#SeqID)
Declare #fs_e int, #C_Tables CURSOR, #Table varchar(50)
SET #C_Tables = CURSOR FOR
select name from sysobjects where OBJECTPROPERTY(id, N'IsUserTable') = 1 AND name like 'TR_%'
OPEN #C_Tables
FETCH #C_Tables INTO #Table
SELECT #fs_e = sdec.fetch_Status FROM sys.dm_exec_cursors(0) as sdec where sdec.name = '#C_Tables'
WHILE ( #fs_e <> -1)
BEGIN
exec('Select * from ' + #Table)
FETCH #C_Tables INTO #Table
SELECT #fs_e = sdec.fetch_Status FROM sys.dm_exec_cursors(0) as sdec where sdec.name = '#C_Tables'
END

Column name not working when placed inside a variable in SQL Server [duplicate]

create procedure sp_First
#columnname varchar
AS
begin
select #columnname from Table_1
end
exec sp_First 'sname'
My requirement is to pass column names as input parameters.
I tried like that but it gave wrong output.
So Help me
You can do this in a couple of ways.
One, is to build up the query yourself and execute it.
SET #sql = 'SELECT ' + #columnName + ' FROM yourTable'
sp_executesql #sql
If you opt for that method, be very certain to santise your input. Even if you know your application will only give 'real' column names, what if some-one finds a crack in your security and is able to execute the SP directly? Then they can execute just about anything they like. With dynamic SQL, always, always, validate the parameters.
Alternatively, you can write a CASE statement...
SELECT
CASE #columnName
WHEN 'Col1' THEN Col1
WHEN 'Col2' THEN Col2
ELSE NULL
END as selectedColumn
FROM
yourTable
This is a bit more long winded, but a whole lot more secure.
No. That would just select the parameter value. You would need to use dynamic sql.
In your procedure you would have the following:
DECLARE #sql nvarchar(max) = 'SELECT ' + #columnname + ' FROM Table_1';
exec sp_executesql #sql, N''
Try using dynamic SQL:
create procedure sp_First #columnname varchar
AS
begin
declare #sql nvarchar(4000);
set #sql='select ['+#columnname+'] from Table_1';
exec sp_executesql #sql
end
go
exec sp_First 'sname'
go
This is not possible. Either use dynamic SQL (dangerous) or a gigantic case expression (slow).
Create PROCEDURE USP_S_NameAvilability
(#Value VARCHAR(50)=null,
#TableName VARCHAR(50)=null,
#ColumnName VARCHAR(50)=null)
AS
BEGIN
DECLARE #cmd AS NVARCHAR(max)
SET #Value = ''''+#Value+ ''''
SET #cmd = N'SELECT * FROM ' + #TableName + ' WHERE ' + #ColumnName + ' = ' + #Value
EXEC(#cmd)
END
As i have tried one the answer, it is getting executed successfully but while running its not giving correct output, the above works well
You can pass the column name but you cannot use it in a sql statemnt like
Select #Columnname From Table
One could build a dynamic sql string and execute it like EXEC (#SQL)
For more information see this answer on dynamic sql.
Dynamic SQL Pros and Cons
As mentioned by MatBailie
This is much more safe since it is not a dynamic query and ther are lesser chances of sql injection . I Added one situation where you even want the where clause to be dynamic . XX YY are Columns names
CREATE PROCEDURE [dbo].[DASH_getTP_under_TP]
(
#fromColumnName varchar(10) ,
#toColumnName varchar(10) ,
#ID varchar(10)
)
as
begin
-- this is the column required for where clause
declare #colname varchar(50)
set #colname=case #fromUserType
when 'XX' then 'XX'
when 'YY' then 'YY'
end
select SelectedColumnId from (
select
case #toColumnName
when 'XX' then tablename.XX
when 'YY' then tablename.YY
end as SelectedColumnId,
From tablename
where
(case #fromUserType
when 'XX' then XX
when 'YY' then YY
end)= ISNULL(#ID , #colname)
) as tbl1 group by SelectedColumnId
end
First Run;
CREATE PROCEDURE sp_First #columnname NVARCHAR(128)--128 = SQL Server Maximum Column Name Length
AS
BEGIN
DECLARE #query NVARCHAR(MAX)
SET #query = 'SELECT ' + #columnname + ' FROM Table_1'
EXEC(#query)
END
Second Run;
EXEC sp_First 'COLUMN_Name'
Please Try with this.
I hope it will work for you.

Search for a string in all databases, all columns, and all tables (SQL Server 2008 R2)

We suffered some kind of invasion in our SQL Server.
I'm trying to find in every database, in every table, every column the word abortion and cheat.
I can do this with this query, but in a single database.
-- Store results in a local temp table so that. I'm using a
-- local temp table so that I can access it in SP_EXECUTESQL.
create table #tmp
(
db varchar(max),
tbl nvarchar(max),
col nvarchar(max),
val nvarchar(max),
);
declare #db nvarchar(max);
declare #tbl nvarchar(max);
declare #col nvarchar(max);
declare #q nvarchar(max);
declare #search nvarchar(max) = 'abortion';
-- Create a cursor on all columns in the database
declare c cursor for
SELECT
DB_NAME(DB_ID()) as DBName, tbls.TABLE_NAME, cols.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLES AS tbls
JOIN INFORMATION_SCHEMA.COLUMNS AS cols ON tbls.TABLE_NAME = cols.TABLE_NAME
-- For each table and column pair, see if the search value exists.
open c
fetch next from c into #db, #tbl, #col
while ##FETCH_STATUS = 0
begin
-- Look for the search key in current table column and if found add it to the results.
SET #q = 'INSERT INTO #tmp SELECT ''' +#db+''',''' + #tbl + ''', ''' + #col + ''', ' + #col + ' FROM ' + #tbl + ' WHERE ' + #col + ' LIKE ''%' + #search + '%'''
EXEC SP_EXECUTESQL #q
fetch next from c into #db, #tbl, #col
end
close c
deallocate c
-- Get results
select distinct db,tbl,col from #tmp
-- Remove local temp table.
drop table #tmp
How can I find these strings? The result set should be:
DATABASE | TABLE | COLUMN
I don't need the result ( text field ), and I need to select distinct for tables and columns, because it will be a lot of abortion in the same table/column.
While the use of the undocumented sp_msforeachdb is generally not encouraged, my instinct would be to send your existing code to this procedure like this:
exec sp_MSforeachdb 'USE [?];
-- Store results in a local temp table so that. I'm using a
-- local temp table so that I can access it in SP_EXECUTESQL.
create table #tmp (
db varchar(max) ,
tbl nvarchar(max),
col nvarchar(max),
val nvarchar(max),
);
declare #db nvarchar(max);
declare #tbl nvarchar(max);
declare #col nvarchar(max);
declare #q nvarchar(max);
--------------------------------------------------------------------------------------------
declare #search nvarchar(max) = ''abortion'';
--------------------------------------------------------------------------------------------
-- Create a cursor on all columns in the database
declare c cursor for
SELECT DB_NAME(DB_ID()) as DBName,tbls.TABLE_NAME, cols.COLUMN_NAME FROM INFORMATION_SCHEMA.TABLES AS tbls
JOIN INFORMATION_SCHEMA.COLUMNS AS cols
ON tbls.TABLE_NAME = cols.TABLE_NAME
-- For each table and column pair, see if the search value exists.
open c
fetch next from c into #db, #tbl, #col
while ##FETCH_STATUS = 0
begin
-- Look for the search key in current table column and if found add it to the results.
SET #q = ''INSERT INTO #tmp SELECT '''''' +#db+'''''','''''' + #tbl + '''''', '''''' + #col + '''''', '' + #col + '' FROM '' + #tbl + '' WHERE '' + #col + '' LIKE ''''%'' + #search + ''%''''''
EXEC SP_EXECUTESQL #q
fetch next from c into #db, #tbl, #col
end
close c
deallocate c;'
The only added code here is the first line, for the rest of the code just make sure to replace ' with ''. The ? in USE [?] is a special character meaning the currently active database in the loop sp_MSforeachdb executes.

How many tables are on an instance of SQL Server

How do I find out how many tables are on my instance of SQL Server? I can get it for a single schema using select count(*) from sysobjects where type = 'U'
(from how to count number of tables/views/index in my database)
You're using the word "schema", but I think you're really asking to count tables across all "databases".
declare #t table (
DBName sysname,
NumTables int
)
insert into #t
exec sp_MSforeachdb N'select ''?'', count(*)
from [?].dbo.sysobjects
where type = ''U'''
select DBName, NumTables
from #t
where DBName not in ('distribution','master','model','msdb','tempdb')
order by DBName
select SUM(NumTables) as TotalTables
from #t
where DBName not in ('distribution','master','model','msdb','tempdb')
An option without using the hidden, undocumented sp_MSforeachdb
declare #sql nvarchar(max)
select #sql = coalesce(#sql + ' + ', '') + REPLACE('
(select count(*)
from ::DB::.sys.objects
where is_ms_shipped = 0
and type_desc = ''USER_TABLE'')', '::DB::', QUOTENAME(name))
from master.sys.databases
where owner_sid != 0x01
select #sql = 'select ' + #sql
exec (#sql) -- returns a single count of all [user] tables in the instance
>
A note on performance. It is insignificant in the greater scheme of things, but with all things interesting, someone is bound to time it. Here is a comparison of the ms_foreachdb approach passing through a temp table (it internally uses a cursor) against the string-concat method.
-- all the variables that we will use
declare #i int -- loop variable
declare #sql nvarchar(max) -- statement var used for 1st approach
declare #t table (DBName sysname, NumTables int) -- table used for 2nd approach
-- init plan cache and buffers
dbcc freeproccache dbcc dropcleanbuffers
print convert(varchar(30), getdate(), 121)
set #i = 0 while #i < 5 begin
set #sql = null
select #sql = coalesce(#sql, '') + REPLACE('
select #c = #c + count(*)
from ::DB::.sys.objects
where is_ms_shipped = 0
and type_desc = ''USER_TABLE''', '::DB::', QUOTENAME(name))
from master.sys.databases
where owner_sid != 0x01
select #sql = 'set nocount on declare #c int set #c = 0 ' + #sql + ' select #c'
exec (#sql)
-- clear plan cache and buffers after each run
dbcc freeproccache dbcc dropcleanbuffers set #i = #i + 1
end
print convert(varchar(30), getdate(), 121)
set #i = 0 while #i < 5 begin
insert into #t
exec sp_MSforeachdb N'select ''?'', count(*)
from [?].dbo.sysobjects
where type = ''U'''
select SUM(NumTables) as TotalTables
from #t
where DBName not in ('distribution','master','model','msdb','tempdb')
-- unfortunately this is required
delete from #t
-- clear plan cache and buffers after each run
dbcc freeproccache dbcc dropcleanbuffers set #i = #i + 1
end
print convert(varchar(30), getdate(), 121)
The result obtained for only 5 invocations (loop iterations) of each. YMMV
start : 2011-01-21 14:21:45.180
end of string-concat : 2011-01-21 14:21:57.497 (12.317)
end of sp_msforeachdb : 2011-01-21 14:22:13.937 (16.440)
It has to be noted that the temp table has to be emptied between each iteration of the 2nd approach, so that could contribute to the total time. It should have been insignificant though
Here is an answer that does not use undocumented functions and works in SQL Server 2005, 2008 and 2008R2. This answer can be used with minor modifications to run any statement across databases.
DECLARE #sql varchar(200), #dbname sysname, #dbid smallint;
CREATE table #alltables
(dbname sysname,
[number of tables] int);
SELECT top 1 #dbname = name, #dbid = database_id
FROM sys.databases
where database_id > 4;
WHILE (#dbname is not null)
begin
-- the statement below could contain any valid select statement
set #sql = 'use ' + #dbname + '; insert into #alltables select ''' + #dbname + ''', count(*) from sys.tables';
EXEC (#sql)
set #dbname = null;
SELECT top 1 #dbname = name, #dbid = database_id
FROM sys.databases
where database_id > #dbid;
end;
select * FROM #alltables;
SELECT sum([number of tables]) "Total Number of Tables in all user databases" from #alltables;
drop table #alltables;
Select Count(*)
From INFORMATION_SCHEMA.TABLES
Where TABLE_TYPE = 'BASE TABLE'
If what you are seeking is a way to determine how many tables exist across all databases on a given SQL Server instance, then you need to cycle through each database. One way would be:
Declare #Databases Cursor
Declare #DbName as nvarchar(64)
Declare #SQL nvarchar(max)
Declare #BaseSQL nvarchar(max)
Declare #Count int
Declare #TotalCount int
Set #Databases = Cursor Fast_Forward For
select [name]
from master..sysdatabases
where [name] Not In('master','model','msdb','tempdb')
Open #Databases
Fetch Next From #Databases Into #DbName
Set #BaseSQL = 'Select #Count = Count(*)
From DatabaseName.INFORMATION_SCHEMA.TABLES
Where TABLE_TYPE = ''BASE TABLE'''
Set #TotalCount = 0
While ##Fetch_Status = 0
Begin
Set #Count = 0
Set #SQL = Replace(#BaseSQL, 'DatabaseName', QuoteName(#DbName))
exec sp_executesql #SQL, N'#Count int OUTPUT', #Count OUTPUT
Set #TotalCount = #TotalCount + #Count
Fetch Next From #Databases Into #DbName
End
Close #Databases
Deallocate #Databases
Select #TotalCount
This solution has the advantage of not using any undocumented features such as sp_MSforeachdb however it is obviously more verbose.

How to create a UDF or View in another database that references the correct sys.objects table in the caller?

Using SQL Server 2008, I'd like to create a UDF that gives me the create date of an object. This is the code:
create function dbo.GetObjCreateDate(#objName sysname) returns datetime as
begin
declare #result datetime
select #result = create_date from sys.objects where name = #objname
return #result
end
go
I'd like to put this UDF in the master database or some other shared database so that it is accessible from anywhere, except that if I do that then the sys.objects reference pulls from the master database instead of the database that I'm initiating my query from. I know you can do this as the information_schema views sit in master and just wrap calls to local instances of sys.objects, so I'm hoping there's a simple way to do that with my UDF as well.
Try this:
CREATE FUNCTION dbo.GetObjCreateDate(#objName sysname, #dbName sysname)
RETURNS datetime AS
BEGIN
DECLARE #createDate datetime;
DECLARE #params nvarchar(50);
DECLARE #sql nvarchar(500);
SET #params = '#createDate datetime OUTPUT';
SELECT #sql = 'SELECT #createDate = create_date FROM ' + #dbName + '.sys.objects WHERE name = ''' + #objname + '''';
EXEC sp_executesql #sql, #params, #createDate = #createDate OUTPUT;
RETURN #createDate
END
;
Why not do this instead?
Create a stored procedure that creates a view in the master database containing all of the information in sys.objects from each database on the server.
Create a DDL Trigger that gets fired whenever a CREATE, ALTER or DROP statement is executed for a database. The trigger would then execute the stored procedure in step #1. This allows the view to be automatically updated.
(Optional) Create a user defined function that queries the view for the creation date of a given object.
Stored Procedure DDL:

Does it have to be a function? If you just want it accessible everywhere, a trick is to put your code in a varchar and sp_executesql it:
create procedure dbo.GetObjCreateDate(#objName sysname)
as
declare #sql nvarchar(max)
select #sql = 'select create_date from sys.objects where name = ''' + #objname + ''''
EXEC sp_executesql #sql
go
There seems to be an undocumented stored procedure that allows you to create your own system objects: sp_ms_marksystemobject
