SET NOCOUNT ON DECLARE @lcl_name VARCHAR(100) DECLARE cur_name CURSOR FOR SELECT name FROM sysobjects WHERE type = 'U' AND crdate <= DATEADD(m,-1,GETDATE()) AND name LIKE 'b_%' OPEN cur_name FETCH NEXT FROM cur_name INTO @lcl_name WHILE @@Fetch_status = 0 BEGIN SELECT @lcl_name = 'sp_depends' +@lcl_name PRINT @lcl_name -- EXEC (@lcl_name) FETCH NEXT FROM cur_name INTO @lcl_name END CLOSE cur_name DEALLOCATE cur_name SET NOCOUNT OFF
Here are a few of the points one should remember with regards to cursors.
- Cursors are nothing but loops as they use WHILE loops
- Overusing cusrors can negatively impact performance of query as they can use too much of the resources
- It is better to use set theory, operations like SELECT…INSERT or INSERT INTO…SELECT rather than cursor to insert one row at one time.
Please note that this is very old blog post and I used it in my production server at that time and till today I use the same logic in my production server after so many years.

As you said that your querry is usefull for print or reindex,
Can u please tell me Wht is the adavntage and disadvantages of re-indexing and wht is the need to reinedxing. When to reindex your table and WHY???
Except and Intersect is not working in MS-SQL 2005…
May i know the solution or way to using these Operators in SQL Server 2005. If there is any possibility to use or not….
So I noticed that when you used NOCOUNT ON, you also used NOCOUNT OFF at the end of the SQL.
Would this be standard programming practice to pair the ON/OFF? Would you still pair it if the SQL was part of a stored procedure, or just use the NOCOUNT ON and leave out the NOCOUNT OFF?
The same can be done without using a cursor
SELECT ‘sp_depends ‘ +name FROM sysobjects
WHERE type = ‘U’
AND crdate <= DATEADD(m,-1,GETDATE())
AND name LIKE 'b_%'
Could we use INFORMATION_SCHEMA instead of sysobjects for the same?
I don’t know what object of INFORMATION_SCHEMA could be used to check the last modified date of a table. I believe we need to involve DMVs here. If there is a work around, please let me know.
i want to do some operation in database in stored procedure… i have to use array data type…..
so if anyone know this… please tell me…..
Thanks for the method. I done it and succeeded.
madhi you couldn’t execute the procedure by using your statement
Thanks & Regards,
