drop constraint in innodb

2002-10-09 Thread kayamboo
sql, query


Hi Folks

ALTER TABLE main_db ADD CONSTRAINT FOREIGN KEY( Code, Kana) REFERENCES
Syoyu_db( Code, Kana) ON DELETE CASCADE ;

works fine.

But how to drop the constraint or modify the constraint ?
Simply changing ADD to DROP or MODIFY throws errors


regards

Curretly you can't drop only foreign key constarints. You should
re-create a table.

Re: drop constraint in innodb

HI

  If suppose my table has thousands of records, is it possible to create a
new table without a foreign key constraint, and then copy the existing data
with the foreign key constraint to the new one ?
