Executing dynamic SQL as follows in Stored Procedure:
DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
SET @city = 'London'
SET @sqlCommand = 'SELECT COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75)', @city = @city
How do I use the count(*) column value as return value in the SP?
DECLARE @sqlCommand NVARCHAR(1000)
DECLARE @count INT
DECLARE @city VARCHAR(75)
SET @city = 'New York'
SET @sqlCommand = 'SELECT @cnt=COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75), @cnt int OUTPUT', @city = @city, @cnt = @count OUTPUT
SELECT @count

ALTER PROCEDURE [dbo].[ReseedTableIdentityCol](@p_table varchar(max))-- RETURNS int
AS
BEGIN
-- Declare the return variable here
DECLARE @sqlCommand nvarchar(1000)
DECLARE @maxVal INT
set @sqlCommand = 'SELECT @maxVal = ISNULL(max(ID),0)+1 from '+@p_table
EXECUTE sp_executesql @sqlCommand, N'@maxVal int OUTPUT',@maxVal=@maxVal OUTPUT
DBCC CHECKIDENT(@p_table, RESEED, @maxVal)
END
exec dbo.ReseedTableIdentityCol @p_table='Junk'
You've probably tried this, but are your specifications such that you can do this?
DECLARE @city varchar(75)
DECLARE @count INT
SET @city = 'London'
SELECT @count = COUNT(*) FROM customers WHERE City = @city
DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
DECLARE @cnt int
SET @city = 'London'
SET @sqlCommand = 'SELECT @cnt=COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75)', @city = @city
RETURN @cnt
this could be a solution?
declare @step2cmd nvarchar(200)
DECLARE @rcount NUMERIC(18,0)
set @step2cmd = 'select count(*) from uat.ap.ztscm_protocollo' --+ @nometab
EXECUTE @rcount=sp_executesql @step2cmd
select @rcount
vMYQUERY := 'SELECT COUNT(*) FROM ALL_OBJECTS WHERE OWNER = UPPER(''MFI_IDBI2LIVE'') AND OBJECT_TYPE = ''TABLE''
AND OBJECT_NAME =''' || vTBL_CLIENT_MASTER || '''';
PRINT_STRING(VMYQUERY);
EXECUTE IMMEDIATE vMYQUERY INTO VCOUNTTEMP ;
