Hello.
perror 152
MySQL error code 152: Cannot delete a parent row
Something prevents your query from deleting a parent row. In my opinion,
it could be some lock from another transaction or query.

Hi List ,
what does error no 152 mean , could not find anything useful from the
manual , was trying to drop a foreign key from an innodb table which has
its corresponding P Key in another table.
Table T_Dropdown (Foreign Key ) references Table T_Questionnaire
( T_QID )
> mysql >alter table T_Dr
