I have created a stored procedure that returns the id of last inserted row of a table based on one condition.
Condition is such that if the row being inserted already exists then it takes identity column of the row otherwise it inserts a new row into the table.
To do this, I have written the following code in a stored procedure
ALTER PROCEDURE [dbo].[Test_Procedure]
@description nvarchar(max)
AS
BEGIN
DECLARE @tempId int;
SELECT CommentId
INTO tempId
FROM TestTable
WHERE description = @description;
IF @tempId IS NULL
BEGIN
INSERT INTO TestTable
VALUES (@description);
SELECT scope_identity();
END
ELSE
BEGIN
SELECT @tempId FROM dual;
END
DROP TABLE tempId;
END
When I run the above stored procedure, first time it ran successfully and then on wards it started throwing the following error message
Msg 2714, Level 16, State 6, Procedure Test_Procedure, Line 15
There is already an object named 'tempId' in the database.
The bit I'm not understanding is tempId
is used as a variable not as a table. I have seen people with the similar problem but in their case they used temporary tables
I really appreciate your help in resolving the above issue.
Try this syntax for setting your variable.
SELECT @tempId = CommentId from TestTable where description = @description;
Currently your 'select into' is creating a table 'tempId' on the database.
