Greetings.

My problem is to find percent character in some field.
I'm wonder how specify percent character or other wildcard characters
in 'LIKE patterns'?

Many thanks in advance,
Sergey.

You have escape them with the backslash. In order to pass the backslash
to the backend you have to escape the backslash as well:

select * from xxx where yyy like '\\%';

It might be a good idea to point this out in the Postgresql book :-)

With kind regards,

If memory serves: "\%"

That is escape char and percent (in this case backslash).
