Seems that transaction is not enabled on my MySQL DB
When running start transaction -> updates -> rollback in MySQL script having set autocommit = 0 I do not get any errors, but the updates are not rolled back. I gave the MySQL user ALL permissions and still the same. Here are some details about the test I'm running. It uses a simple table, created with: "create table a ( id serial primary key);" Following is the test script: delete from a; set autocommit = 0; start transaction; insert into a(id) values(1); rollback work; select count(*) from a; So the script makes sure the table is empty, Then it starts a transaction, insert a row and rollback the insert. As the "insert" was rolled back, the "select" should indicate that table still contains 0 rows. Running this on PostgreSQL: $ psql < test1 DELETE 0 START TRANSACTION INSERT 0 1 ROLLBACK count 0 This is the expected behavior, 0 rows in the table as the insert was rolled back. Running the same on my MySQL DB: $ mysql -u < test1 count(*) 1 Having 1 row following the rollback indicate that the "insert" was NOT rolled back, just as in non-transaction mode.
