Export MySQL Table (only structure) AUTOINCREMENT error

[mmendivilg]

Steps to reproduce

1.Have a MySQL Database with a Table with a int primary key with autoincrement
2.Have Data in your table
3.Select the Database from the left database menu (tree)
4.Click on Export from the top menu.
5.Check "Custom - display all possible options"
6.Uncheck the "data" from the export options (export only structure)

Expected behaviour

ALTER TABLE bank_account_statements
MODIFY id_bank_account_statement int(11) NOT NULL AUTO_INCREMENT;
COMMIT;

Actual behaviour

-- See that AUTO_INCREMENT = 4 should not be there. Since I want to export a table with no data.

ALTER TABLE bank_account_statements
MODIFY id_bank_account_statement int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=4;
COMMIT;

This only affects database-level exports, table-level exports seem to be fine.

Also, both QA_4_7 and master are currently affected.

In table-level exports, when selecting structure only, the AUTO_INCREMENT value will be auto disabled (so does in server-level exports).

In database-level exports, the structure or data options of tables could be diverse, and the single AUTO_INCREMENT value will not work for all the tables for sure (enable by default). That's what causes this bug. I'll try to fix it.
