-------------------------------------
Hi,
your patch does doesn't work properly. When importing the same table with your patch I'm getting following error:
{code}

{code}
which is to be expected as just calling {{SELECT t.* FROM "USER_MG_DEV_HAVLIKJ_A2.MD_BRICKS_TEST3" t WHERE 1=0}} is not valid in Oracle and does not work when executing directly in SQL.
