Sorry I got carried away in my former response.
When I tried this,
ALTER IGNORE TABLE tbl_name DROP INDEX seems to fail if the index does not
exist.
The DROP INDEX statement is part of a larger script, what I want is for the script to conue to
execute if this index does not exist.
e.g.
ALTER IGNORE TABLE table_name DROP INDEX index_name;
ALTER IGNORE TABLE table_name ADD INDEX UNIQUE index_name(column_1,column_2);
Thanks - Ada

Folks
How can one conditionally drop an index in MySQL?
Googling shows that the "drop index" does not support an "if exists" qualifier
- apparently a bug
has been raised but as far as I know its not fixed yet.
Does anyone know of a work-around?
TIA - Adam
Sent my first response late at night and not the community... And the
response also sucked.
DROP INDEX is mapped to ALTER TABLE tbl_name
DROP INDEX.
ALTER IGNORE TABLE tbl_name
DROP INDEX ought to be functionally equivalent to IF EXISTS. What is your goal?
