In this case the idea is to have lots of identical tables. But they would contain different data. The name of the table would be for instance TAB_2018_06_27, TAB_2018_06_28 so I could use date expression to get a proper table. But I have no idea how to specify that I need all logins from TAB_2018_06_27 not from any other tables which contains same column named 'login'.
