Thread: Expression matching related question

Hi,

I wish to do a query such as:
SELECT * FROM table WHERE column='something' AND column2='something
else' AND (network='0' OR (left=0 AND network>0));

However, when I execute this in phppgadmin I'm told there is an error
around the = character in left=0. Can't seem to figure the syntax.

Help would be appreciated.

Regards,
Peter Hoskin

I should of mentioned, left is a bigint and network is an integer

If you're using reserved words like table, column, and left as
identifiers then you'll need to double-quote them.  Better yet,
avoid using reserved words as identifiers.

LEFT is a reserved word, isn't it?  If you're going to insist on naming
a column "left", you'll have to double-quote the name every time.
