Question

I have a db in sql 2008 with 40 tables:

On each table there is a DateTime column ranging from

2010-01-01 09:00:00.000 up to 2012-01-23 22:00:00.000

I need a query to delete data for all tables only in time range from 17:31:00.000 up to 22:00:00.000

Result would be in having same days as of now but with time range from 09:00:00.000 to 17:30:00.000

Help me regarding this.

Thank you very much

Answer 1

DELETE FROM YourTable
WHERE CAST(DateTimeColumn AS TIME) BETWEEN '17:31' AND '21:59'

For all the tables use this:

EXEC sp_msforeachtable N'DELETE FROM ? WHERE CAST(DateTimeColumn AS TIME) BETWEEN ''17:31'' AND ''21:59'''

But I have a doubt about that ALL your tables have the same column 😎

If you want to check what errors appeared during run, try this:

EXEC sp_msforeachtable N'PRINT ''?''; BEGIN TRY DELETE FROM ? WHERE CAST(DateTimeColumn AS TIME) BETWEEN ''17:31'' AND ''21:59''; END TRY BEGIN CATCH PRINT ERROR_MESSAGE() END CATCH'
