I need to store a query as a stored procedure in SQL Server.
I need also to pass parameters which define tablenames and column names.
This is the query I owuld like to have, I tried to store it in a string and then EXECUTE it but without success, ho can I solve this?
CREATE PROCEDURE sp_selectAllParents #id int, #tableid varchar(30), #tablename varchar(30)
AS BEGIN
SET NOCOUNT ON;
WITH ct AS (
SELECT * FROM #tablename t WHERE #tableid = #id
UNION ALL
SELECT t.* FROM #tablename t JOIN ct ON t.parentId = ct.#tableid
)
SELECT * FROM #tablename t WHERE #tableid NOT IN (SELECT #tableid FROM ct)
END
EDIT:
my attempt was:
DECLARE #sql varchar(255)
SET #sql = 'WITH ct AS (SELECT * FROM #tablename t WHERE #tableid = #id UNION ALL SELECT t.* FROM #tablename t JOIN ct ON t.parentId = ct.#tableid) SELECT * FROM #tablename t WHERE #tableid NOT IN (SELECT #tableid FROM ct)'
EXEC(#sql)
As I already in the comment section, it is a bad idea to do this. You should really rethink your solution.
The Stored Procedure would have to look like this:
CREATE PROCEDURE selectAllParents #id int, #tableid sysname, #tablename sysname
AS
BEGIN
SET NOCOUNT ON;
-- Guards against SQL Injection attacks (replace ' with '')
SET #tableid=REPLACE(#tableid,'''','''''');
SET #tablename=REPLACE(#tablename,'''','''''');
DECLARE #stmt NVARCHAR(4000);
SET #stmt=
';WITH ct AS ('+
'SELECT * FROM ' + QUOTENAME(#tablename) + ' t WHERE ' + QUOTENAME(#tableid) + '= #id ' +
'UNION ALL ' +
'SELECT t.* FROM ' + QUOTENAME(#tablename) + ' t JOIN ct ON t.parentId = ct.' + QUOTENAME(#tableid) +
')'+
'SELECT * FROM ' + QUOTENAME(#tablename) +' t WHERE ' + QUOTENAME(#tableid) + ' NOT IN (SELECT ' + QUOTENAME(#tableid) +' FROM ct);';
EXEC sp_executesql
#stmt,
N'#id int',
#id;
END
GO
if your are sending Table name as parameter in that case you need to create dynamic query string. may help below script
CREATE PROCEDURE sp_selectAllParents #id int, #tableid varchar(30), #tablename varchar(30)
AS BEGIN
SET NOCOUNT ON;
SET #query=N'WITH ct AS (
SELECT * FROM #tablename t WHERE #tableid = #id
UNION ALL
SELECT t.* FROM #tablename t JOIN ct ON t.parentId = ct.#tableid
)
SELECT * FROM #tablename t WHERE #tableid NOT IN (SELECT #tableid FROM ct)'
EXECUTE sp_executesql #query, #id,#tablename,#tableid
END

I have a dynamic query that pulls from a list of tables with the names of those stored in another table but I would like to be able to use the resulting set in another query.
declare #t table( tablename varchar(50))
declare #sql varchar(max)
set #sql = ''
insert into #t
SELECT t.svc_table AS table_name FROM svc_defs AS t
SELECT #sql = #sql + 'Select convert(varchar(5),svc_defs.svc_id) as svcid, data_id, crid, d_custid, d_active From ' + tablename +
' inner join svc_defs on svc_defs.svc_table = ' + '''' + tablename + '''' + ' union ' from #t
--remove the trailing 'union'
Select #sql = substring(#sql, 1, len(#sql) - 6)
exec (#sql)
You can create scalar user defined function, which returns the sql statement.
CREATE FUNCTION dbo.udf_GenerateSelectQuery()
Returns nvarchar(max)
AS
BEGIN
declare #t table( tablename SYSNAME)
declare #sql Nvarchar(max)
set #sql = ''
insert into #t
SELECT t.TABLE_NAME AS table_name FROM INFORMATION_SCHEMA.TABLES AS t
SELECT #sql = #sql + 'Select convert(varchar(5),svc_defs.svc_id) as svcid, data_id, crid, d_custid, d_active From ' + tablename +
' inner join svc_defs on svc_defs.svc_table = ' + '''' + tablename + '''' + ' union ' from #t
--remove the trailing 'union'
Select #sql = substring(#sql, 1, len(#sql) - 6)
RETURN #sql
END
you can call it as
declare #sqlstmt NVARCHAR(max) = dbo.udf_GenerateSelectQuery()
SELECT #sqlstmt
or as
declare #sqlstmt NVARCHAR(max)
SET #sqlstmt = (SELECT dbo.udf_GenerateSelectQuery())
SELECT #sqlstmt
I want to write a function that counts non null and non empty entries of a field. My problem is that the query does not run since the #tableName variable is not recognized in the select statement and I do not know why
create function dbo.getCount(#cod int, #columnName as varchar(20), #tableName as varchar(20))
Returns int as
Begin
--Count all filled entries
Return (select COUNT(*) from #tableName
where #columnName <> '' and #columnName is not null)
End;
go
As mentioned in the comments, but to reiterate, as I'll delete them after this answer:
You can't do this with a function, for multiple reasons. SELECT
COUNT(*) FROM #TableName means count the number of rows in the
table variable #TableName not the table who's name is the value of #TableName. WHERE #ColumnName <> '' would mean where the value of the scalar variable doesn't have the value '',
not where the column (in the aforementioned table) with the name of value of #ColumnName doesn't have the value ''.
And you can't do this in a function as to do this type of thing, you
need dynamic SQL; and you can't use dynamic SQL in a function (as you
can't use the EXEC command).
You can, however, do this with a Stored Procedure:
CREATE PROC dbo.GetCount #SchemaName sysname = N'dbo', #TableName sysname, #ColumnName sysname, #Count int OUTPUT AS
BEGIN
DECLARE #SQL nvarchar(MAX),
#CRLF nchar(2) = NCHAR(13) + NCHAR(10);
SELECT #SQL = N'SELECT #Count = COUNT(NULLIF(' + QUOTENAME(c.[name]) + N',''''))' + #CRLF +
N'FROM ' + QUOTENAME(s.name) + N'.' + QUOTENAME(t.[name]) + N';'
FROM sys.schemas s
JOIN sys.tables t ON s.schema_id = t.schema_id
JOIN sys.columns c ON t.object_id = c.object_id
WHERE s.[name] = #SchemaName
AND t.[name] = #TableName
AND c.[name] = #ColumnName;
--PRINT #SQL; --Your debugging friend
EXEC sp_executesql #SQL, N'#Count int OUTPUT', #Count OUTPUT;
END
GO
And you run the SP like below (with sample table):
CREATE TABLE dbo.TestTable (SomeColumn varchar(10));
INSERT INTO dbo.TestTable (SomeColumn)
VALUES(''),('abc'),(NULL);
GO
DECLARE #Count int;
EXEC dbo.GetCount #TableName = N'TestTable', #ColumnName = N'SomeColumn', #Count = #Count OUTPUT;
SELECT #Count; --Returns 1
GO

i am using sql server 2008 r2, I have created a dynamic stored procedure because this is my requirement to implement to filteration of data based on certain conditions. I am not able to get value into #RecordCount
ALTER PROCEDURE [dbo].[sp_getAssetListAudit]
#type nvarchar(20),
#typeid nvarchar(5),
#clientId nvarchar(5),
#PageIndex nvarchar(5),
#PageSize nvarchar(5),
#RecordCount nvarchar(5) output
AS
BEGIN
SET NOCOUNT ON;
DECLARE #SQL nvarchar(max)
SET #SQL ='
select ROW_NUMBER() OVER ( ORDER BY ad.arid ASC )
AS rownum, ad.arid,ad.ast_code,ad.ast_descp,isnull(cat.name,'''') ''cat'',ISNULL(loc.name,'''') ''loc'',isnull(gp.name,'''') ''grp'',
isnull(cc.name,'''') ''cc'' ,
ad.ast_qty ''qty'' into #Results
from tbl_AssetDetails ad
left join tbl_Category cat on ad.ast_cat = cat.catid
left join tbl_Subcategory scat on ad.ast_subcat = scat.subcatid
left join tbl_Location loc on loc.lid = ad.ast_loc
left join tbl_Group gp on gp.gid = ad.ast_grp
left join tbl_CostCenter cc on cc.ccid = ad.ast_costcen
where ad.ast_status not in (3,-1) AND ad.clientId = '+#clientId+' AND '
IF(#type='cat')
SET #SQL = #SQL +' ad.ast_cat='+#typeid+' AND '
IF(#type='subcat')
SET #SQL = #SQL +' ad.ast_subcat='+#typeid+' AND '
IF(#type='loc')
SET #SQL = #SQL +' ad.ast_loc='+#typeid+' AND '
IF(#type='grp')
SET #SQL = #SQL +' ad.ast_grp='+#typeid+' AND '
IF(#type='cc')
SET #SQL = #SQL +' ad.ast_costcen='+#typeid+' AND '
IF(#type='ast')
SET #SQL = #SQL +' ad.arid='+#typeid+' AND '
SET #SQL = #SQL +' 1=1 '
SET #SQL =#SQL + ' SELECT '+#RecordCount+' = count(*) FROM #Results '
SET #SQL = #SQL +' SELECT * FROM #Results WHERE rownum
BETWEEN('+#PageIndex+' -1) * '+#PageSize+' + 1 AND((('+#PageIndex+' -1) * '+#PageSize+'+ 1) + '+#PageSize+') - 1 '
SET #SQL = #SQL + ' drop table #Results '
EXEC sp_executesql #SQL, #RecordCount OUTPUT
END
I am not able to get value into #RecordCount and subsequently no result set.
You need to assign the value to the OUTPUT parameter:
SET #SQL =#SQL + ' SELECT #RecordCount = count(*) FROM #Results; '
You also need to pass the parameter definitions to sp_executesql as in #wannuanguo's answer. You should use also use parameters for #typeid, #pageindex, etc. too instead of literals in the query.
Add the second parameter for sp_executesql:
EXEC sp_executesql #SQL, N'#RecordCount nvarchar(5) output',#RecordCount OUTPUT
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
I am trying to print a selected value, is this possible?
Example:
PRINT
SELECT SUM(Amount) FROM Expense
You know, there might be an easier way but the first thing that pops to mind is:
Declare #SumVal int;
Select #SumVal=Sum(Amount) From Expense;
Print #SumVal;
You can, of course, print any number of fields from the table in this way. Of course, if you want to print all of the results from a query that returns multiple rows, you'd just direct your output appropriately (e.g. to Text).
If you're OK with viewing it as XML:
DECLARE #xmltmp xml = (SELECT * FROM table FOR XML AUTO)
PRINT CONVERT(NVARCHAR(MAX), #xmltmp)
While the OP's question as asked doesn't necessarily require this, it's useful if you got here looking to print multiple rows/columns (within reason).
If you want to print multiple rows, you can iterate through the result by using a cursor.
e.g. print all names from sys.database_principals
DECLARE #name nvarchar(128)
DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals
OPEN cur
FETCH NEXT FROM cur INTO #name;
WHILE ##FETCH_STATUS = 0
BEGIN
PRINT #name
FETCH NEXT FROM cur INTO #name;
END
CLOSE cur;
DEALLOCATE cur;
set #n = (select sum(Amount) from Expense)
print 'n=' + #n
I wrote this SP to do just what you want, however, you need to use dynamic sql.

If you want to print more than a single result, just select rows into a temporary table, then select from that temp table into a buffer, then print the buffer:
drop table if exists #temp
-- we just want to see our rows, not how many were inserted
set nocount on
select * into #temp from MyTable
-- note: SSMS will only show 8000 chars
declare #buffer varchar(MAX) = ''
select #buffer = #buffer + Col1 + ' ' + Col2 + CHAR(10) from #temp
print #buffer
Add
PRINT 'Hardcoded table name -' + CAST(##RowCount as varchar(10))
immediately after the query.
You can also use the undocumented sp_MSforeachtable stored procedure as such if you are looking to do this for every table:
sp_MSforeachtable #command1 ="PRINT 'TABLE NAME: ' + '?' DECLARE #RowCount INT SET #RowCount = (SELECT COUNT(*) FROM ?) PRINT #RowCount"
If you wish (like me) to have results containing mulitple rows of various SELECT queries "labelled" and can't manage this within the constraints of the PRINT statement in concert with the Messages tab you could turn it around and simply add messages to the Results tab per the below:
SELECT 'Results from scenario 1'
SELECT
*
FROM tblSample
Try this:
DECLARE #select as nvarchar(max) = ''
SELECT #select = #select + somefield + char(13) FROM sometable
PRINT #select
