Recommended Posts

Hi

 

I have installed on my computer php myadmin which came with the wampserver i downloaded

 

I have a table called Form and within that table i have the record called EmployeeID which is a foreign key from the employee table.

 

This has been set to Index for some reason, i now to delete this record (or drop it )but i get this error -

 

SQL query:

 

ALTER TABLE `form` DROP INDEX `employeeID`

 

MySQL said: 

 

#1025 - Error on rename of '.\helpdesk\#sql-90c_91' to '.\helpdesk\form' (errno: 150)

 

 

Can anyone shed some light on this

 

Thanks
