Can't delete any foreign key on every query to drop foreign key

[haji1222]

mysql> alter table employee_salary drop foreign key empid;
ERROR 1025 (HY000): Error on rename of '.\hjj\employee _salary' to '.\hjj\#sql2-16c-1' (errno: 152)

check if the name of foreign key you mentioned is correct

[PreethiGowri]

use the following query to known the name of the foreign key

SHOW CREATE TABLE table_name

you can also use the constraint name rather than the column name of the foreign key
