does delete * from table name work??
Jorge Mederos (2 years ago)
angel aiyappa - no because the delete statement deletes a row of data not a field so it isnt necessary to tell SQL to include all fields by specifying "*"

sorry, this isn't the correct platform for the type of questions you are asking. my recommendation is to submit your generic questions on a SQL forum. there are plenty out there. otherwise, your comments and mine will fill pages on this site.

thanks for your reply .. actually i m not master at SQL .. i have not done anything yet .. . please if possible tell me .. wether i should type ( Date< required date) or (day-100,getdate ..) please sir explain once

you should always try and when you reach out for help, tell others what problem you are having and what you have tried. you will learn the material much better with this approach. DELETE FROM tblName WHERE [datefield] < DATEADD(day, -100, GETDATE())

The favorite statement of black hats.

Are you supplying the correct format for the date? The format should match the field's format. It looks like this is C# code, have you tried to run the query (or in the case a nonQuery) from the DB Management interface, I assume MSSQL here, so MSSQL Management Studio?

May i ask why my query is String sql = "delete from Schedule where sch_date < '17/07/2013'"; and the sch_date in database is date datatype, when i run, it give me the datatype mismatch error

@multimediaarts - Depends, but if you have a unique primary key in this table, just append the where clause, the field name does not equal 1. (If i write the sql statement, youtube prevents me from posting the answer.). If you need help, go to my site, itegared.com, and go to the forum section. I can continue to help you there.
