MySql Index and constraints

Question

I need to drop all indexes and constraints and do some processing, after thar I have to apply same indexes and constraints again using MYSql.Please help.

Please suggest if there is some way to store the information/metadata of index created.

Answer 1

Start by disabling all constraints:

 ALTER TABLE my_tbl NOCHECK CONSTRAINT ALL

Primary keys and unique constraints can't be disabled.

Then reenable them again:

 ALTER TABLE my_tbl WITH CHECK CHECK CONSTRAINT ALL
