In SQL Server I used the following code to drop a table with a constraint:
IF OBJECT_ID('EMPLOYEES') IS NOT NULL
BEGIN
ALTER TABLE EMPLOYEES DROP CONSTRAINT EMP_DEPT_FK
DROP TABLE EMPLOYEES;
END
How can I accomplish the same thing in Mysql?

You can use information_schema
to check if the table exists but in MySQL there is a simpler method:
DROP TABLE IF EXISTS employees ;
