I am having SQL server 2008 and i am having 10 different databases in it and now i want to search one stored procedure that in which database the stored procedure is present.
Mentioned as duplicate by some ..... with out reading my question properly. My Requirement is i need to verify 'SP_Email' procedure. I which database is this procedure exists.
You can try this:
EXEC sp_msforeachdb
'if exists(select 1 from [?].sys.objects where name=''SP_Email'')
select ''?'' as FoundInDatabase from [?].sys.objects where name=''SP_Email'''
Please try this.
SELECT name DatabaseName
FROM sys.databases
WHERE OBJECT_ID(QUOTENAME(name) + '.dbo.ProcedureNameHere', 'P') IS NOT NULL;
This will return the database(s) name in which this particular object exist.
Replace ProcedureNameHere with your procedure name. In your case it would be SP_Email Keep rest of the things as it is.
you need to query sys.databases of master database to get list of databases and for each database name you get you need to query the db_name.sys.procedures to check if it exists.
try below query and give a feedback:
use master
go
declare #FullQuery varchar(max)
declare #DBName varchar(50)
set #FullQuery=''
declare cr cursor for select name from sys.databases where database_id > 4
open cr
fetch next from cr into #DBName
while(##fetch_status=0)
begin
set #FullQuery=#FullQuery+
' select name COLLATE SQL_Latin1_General_CP1_CI_AS from '+#DBName+'.sys.procedures where name like ''%proc_name%'' union'
fetch next from cr into #DBName
end
close cr
deallocate cr
set #FullQuery=substring(#FullQuery,1,len(#FullQuery)-5)
exec (#FullQuery)
SELECT OBJECT_ID('DataBase1.SchemaName.StoredProcedureName') /
OBJECT_ID('DataBase2.SchemaName.StoredProcedureName') /
OBJECT_ID('DataBase3.SchemaName.StoredProcedureName') /
...
It will return NULL if there is no such procedure. This will work if all databases are on same instance.

It is possible in SSMS to run the same query on some databases?
I was thinking something like an array with database names and cycling through it, maybe with SQLCMD mode.
some pseudocode:
:setvar arr ["db1", "db2", "db3"]
foreach $db in $arr
:setvar database $db
use $(database)
go
select * from table
Thanks

Here's an example using two of my databases (Staging and Warehouse) to hit the sys.columns table in each. Just change out the IN filter with the names of whichever databases you want, and the ".sys.columns" with the schema/table name you need.
DECLARE #query NVARCHAR(MAX) = ''
;
SELECT #query += CONCAT('SELECT * FROM ',[name],'.sys.columns;')
FROM sys.databases
WHERE [name] IN ('Staging','Warehouse')
;
EXEC sp_executesql #query;
You can do this with a Local Server Group as well.
View --> Registered Servers
Right-click Local Server Group and create new
Add new server registrations to the group (any databases you want to query). Be sure to specify the database in the Connection Properties tab
Now you can right-click the Local Server Group folder and execute a new query, which will run on all the databases in that folder.
I use a piece of code to loop through all the databases on an MS SQL server. It works fine for altering a column on a table and also for updating the data. But I continue to get errors when trying to alter a stored procedure. Here is the code:
use master
declare #dbname varchar(100)
,#sql varchar(max)
declare db_cur cursor for
SELECT name
FROM sys.databases where ([name] like 'ce%')
and [state] = 0
open db_cur
fetch next from db_cur into #dbname
while ##FETCH_STATUS = 0
begin
set #sql=
'ALTER TABLE ['+#dbname+'].[dbo].MyStuff
ADD myNewColumn bit NULL DEFAULT(0)
'
exec(#sql)
fetch next from db_cur into #dbname
end
close db_cur
deallocate db_cur
So the code above works perfectly fine. But when I alter that code to instead do an alter stored procedure I receive the message below:
'CREATE/ALTER PROCEDURE' does not allow specifying the database name as a prefix to the object name.
I realized that the message stated I can't use the database name in the front of the procedure like I was doing here: ALTER procedure ['+#dbname+'].[dbo].[spSelectSomething]. But I haven't been able to figure out a way around the issue. Thanks for your help.
You need to nest dynamic SQL for this task because a proc CREATE or ALTER must be the first statement in the batch:
SET #sql= N'EXEC(N''USE ' + QUOTENAME(#dbname) + N';EXEC(N''''CREATE PROC...;'''')'')';
I need to TRIM databases as per requirement. So, I'm using below script and giving database names manually. All I need is to automate the script to get database names automatically. Can anyone please suggest how to get the database name automatically.
Use [Sales_backup_2015_05_31_230001_7137975]
Exec [spMaint_TrimTestDB] 1
Go
for Eg:
instead of giving manually Sales_backup_2015_05_31_230001_7137975 I need to get db name automatically
Thanks.
There is a function DB_NAME() that would return the name of the current database if no parameters are passed. Check this.
I guess dynamic SQL might help you to run SP in different databases:
DECLARE #sql nvarchar(max)
SELECT #sql = (
SELECT N'Use '+QUOTENAME([name]) +' Exec [spMaint_TrimTestDB] 1;'
FROM sys.databases
WHERE database_id >= 5 AND [name] like 'Sales_backup%'
FOR XML PATH('')
)
EXEC sp_executesql #sql
This script will create and execute dynamic statement like:
Use [sales_backup_2015] Exec [spMaint_TrimTestDB] 1;
Use [sales_backup_2016] Exec [spMaint_TrimTestDB] 1;
etc...
I have db A and db B. At the beginning of a stored procedure I want to back up all rows from B.mytable to B.mytablebackup. The rest of the stored procedure runs against tables on db A (which gathers data and writes it to B.mytable).
So I check to see if B.mytablebackup exists
IF EXISTS(SELECT 1 FROM B.dbo.mytablebackup)
and if it does, the stored procedure does an
INSERT INTO B..mytablebackup SELECT * FROM B..mytable
If it doesn't exist it does a
SELECT * INTO B..mytablebackup from B..mytable
But when I execute the stored procedure I get the error
There is already an object named 'mytablebackup' in the database
I added a Print statement and execution is taking the "does not exist" branch of the IF.
What am I doing wrong?
For SQL Server, you should use system view sys.tables to check if table exists.
IF EXISTS(SELECT 1 FROM B.sys.tables WHERE name = 'mytablebackup')
OBJECT_ID can be used too:
IF OBJECT_ID('B.dbo.mytablebackup') IS NOT NULL
You can directly check from the given DB,SCHEMA and TABLE parameters (For dynamic database, schema and table use)
DECLARE #targetdatabase NVARCHAR(MAX),
#SchemaName NVARCHAR(MAX),
#TableName NVARCHAR(MAX)
DECLARE #TempTableName NVARCHAR(MAX) = QUOTENAME(#targetdatabase) + '.' +
QUOTENAME(#SchemaName) + '.' + QUOTENAME(#TableName)
IF OBJECT_ID(#TempTableName) IS NULL
BEGIN
PRINT #TempTableName
END
I would like to print out database users of an actual database in a SP procedure (see the code of sp_PrintUsers below), however, for some reason it print out database users of master. It seems that it is a general behavior of SP procedure for all database-level views despite the fact that any database-level SQL statement is executed in the actual database. If we print out the DB_NAME that it is clearly not master, so what is wrong?
Is there any workaround?
use [master]
go
create procedure sp_PrintUsers
as
begin
SELECT DB_NAME() AS DataBaseName
select name from sys.database_principals;
end
go
use [actual_database]
go
exec sp_PrintUsers
Try executing the select dynamically as in:
EXEC('select name from sys.database_principals;');
If that does not help build the query to reference the catalog view with a three part name.
Try this :
use [master]
go
create procedure sp_PrintUsers
as
begin
declare #dbname varchar(30) = DB_NAME()
EXEC ('select name from ' + #dbname + '.sys.database_principals');
end
go
use [actual_database]
go
exec sp_PrintUsers
