How do you specify multiple DBs in VB's Data-control-SQL(Recordsource property)?
Im using vb5.0

(I need to match entries from 2 different .mdb files using a sql statement in the data-control.)

From table1's database, use this query.

select table1.*, table2.*
  from table1 inner join table2 in "c:\path\to\other\mdb.mdb"
    on table1.column1 = table2.column1

This might work in some cases anthony, but the only column in table 1 corresponding to a column in table 2, in my case, does not always have matching entries. This is the whole problem. I want to find out (with SQL) wich entries does have matching entries and wich not.

sorry, but the answer is not that simple...

yes, the answer >IS< that simple.  Please try something before you bash it.

select table1.*, table2.*
  from table1 left join table2 in "c:\path\to\other\mdb.mdb"
    on table1.column1 = table2.column1
 where isnull(table2.column1)

will return all records that are in table1 and NOT in table 2.
