mysql 5.6 alter table drop列（如果存在）

Question

i'm asking this question after googling with no luck. it has been asked before on SOF but that's long ago MySQL Alter syntax to drop a column if it exists . Hope things have changed since.

Is there a straight forward way to drop a column in table if it exists.

I'm using MySql 5.6, i would like to wrap this alter statement around an if to avoid any issue if the script runs twice:

ALTER TABLE xyz DROP COLUMN abc, ADD COLUMN ghi DATE NOT NULL AFTER column4;

Thanks

You may check if column exists and after perform the other operations.
