Re: update syntax - Mailing list pgsql-sql

Thanks. The UPDATE works ok now. But using the same logic it doesn’t seem possible to delete rows. Is this also possible?

Subject: [SQL] update syntax

 

Hi,

 

While using Ms SQL server I used to write update statements like this,

 

UPDATE a SET a.col1 = b.col1

FROM table1 a

INNER JOIN table1 b

ON a.col2 = b.col2

WHERE a.col3 = ‘something’

AND b.col3 = ‘somethingelse’

 

But I can’t seem to do this in postgres, it gives me an error saying ‘syntax error at or near “.”’. How can I do something similar to this i.e. join on the same table?

 

Thanks,

/P
