db2 has one table “table1”:
id int
name char
bike char
If you use Structure Synchronization Tool to update (synchronize) db1 SQLyog 3.71 creates this:
alter table `db1`.`table1`,
drop column `car`,
add column `bike` char(1) NULL after `car`;
If you execute the query:
Error Code : 1054
Unknown column 'car' in 'table1'
You cannot refer to the 'car' field that you've just dropped !!!
