Re: Flat File unload/export/copy

Regina,
I wasn't aware that you could!
I just tried and that syntax gave me an error:
rel_reinsure=# copy (select * from client where name like '%BERT%') to
'/tmp/stevet.clients';
ERROR: syntax error at or near "(" at character 6
LINE 1: copy (select * from client where name like '%BERT%') to '/tm...

- I can do though:
rel_reinsure=# copy client (recno,code,name) to '/tmp/stevet.clients';

... or select all columns, but that is 'too global' and I just want
'WHERE name LIKE '%BERT%' type syntax.
