  • Ticket #29377 – Description

    initial v3  
    1 This feature request is to better support  of third-party database backends.
    2 In my case (Firebird SQL) to add a new field on already existing and populated table is not enough set and drop a default value, we need to update the new field with efective default value. It is not possible without commit the schema alteration.
     1A nice option would be to have a hook to run DML statements after all migrations were applied and commited.

     3A uses case  (for example in Firebird SQL) is to add a new field on already existing and populated table. Is not enough set and drop a default value, we need to update the new field with efective default value. It is not possible without commit the schema alteration.
    34An aproach could be to have a kind of hook to run sql statements (DML statement in this case) when the schema  altereation finished (and commited). Of course, must bu runned in another transaction.
