Subject RE : Problem with setDistinct()
Date Wed, 02 Mar 2005 13:43:45 GMT




Hi Frederic,

It is not the primary keys of the table, it is all columns of the table
that are compared by a DISTINCT. So if any column is a text, ntext or
image, you have a problem.

Just to make sure it is not a JDBC problem: did you try to execute the SQL
statement in a console ? If yes, did it give the same message ?

To find the reason why no column names appear (which could be the reason
for the problem if the Salarie table does not contain text, ntext or
image), which Torque version are you using ? You could also try to add
select fields "by hand" and see what happens.

          Thomas
