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
It needs this physical (4) too. Else there is no way to store the values of tab_2.col_2. The logical tables are different. If you would like some table to reuse columns of an other table, you should create a view. Niels
or Just
PHYSICAL_TAB_3 OID , COL_3
Thanks Sateesh
