Re: DELETE with no WHERE clause

[Dennis Salguero]

I can not confirm this, but it would make sense that this was updated in
4.05. After all, you are only deleting your records, not re-building the
table. The new functionality you describe is also present in SQL Server and
Oracle.

Filter: Mysql , sql , query

Good Luck,

Dennis Salguero
