  Apologies if this has been asked before, but I need help with multiple left outer joins as below :

  I want to do a left outer join between table A and Table B (No problem).

  I also want to do a Left outer join between table A and Table C in the same query. Can't get the syntax to work on this one.

  I've tried variations on the syntax below, all of which incur syntax errors :

  Select <col list> from

  tablea left outer join tableb left outer join tablec on

  (<Table a - table b join condition>),

  (<Table a - table c join condition>)

  Any ideas ?

  Regards

  Try:-

  select

  <col list>

  from

  a

  left outer join b on a.? = b.?

  left outer join c on a.? = c.?

  Or as you had started

  Select <col list> from

  tablea left outer join tableb left outer join tablec

  on

  (<Table a - table b join condition>)

  on

  (<Table a - table c join condition>)

  will work as well you just have to create a seperate on for each join and the conditional cols of the join.
