Hi All, If i create two logical tables which has the same column then when MonetDB actually creates the Physical Tables does it create two tables for this Column.. For Ex: I created these two Tables at the Logical Level.. TAB_1 col_1 varchar(100), col_2 int TAB_2 col_3 varchar(256), col_2 int Now I home MonetDB will create these physical tables.. For TAB_1 PHYSICAL_TAB_1 PHYSICAL_TAB_2 OID , COL_1 OID , COL_2 How abt for TAB_2 Does it create PHYSICAL_TAB_3 PHYSICAL_TAB_4 OID , COL_3 OID , COL_2 or Just PHYSICAL_TAB_3 OID , COL_3 Thanks Sateesh -- View this message in context: http://www.nabble.com/Info-reg-the-Physical-Tables..-tp14692698p14692698.htm...
