Yes, the employee id=1 and it is text. So I agree with you that could be a space problem. How can I resolve that? May
bechange id as integer or real?
Thanks.

Is there an employee with id='1'? What data type is the id column?
If it's a string type (char, varchar, text) then I wonder if the
data has extraneous whitespace. I mentioned this in my original
reply, and I asked you to run a query like the following:
SELECT '<' || id || '>', name FROM employee WHERE id LIKE '%1%';
Please run that query and look closely at whether there are spaces
around the id value. If the query doesn't return what you expect,
then please post the query you ran and show the record you expect
it to match. It might be useful to see that record as the output
of the following command:
pg_dump -t employee -aD | grep 'something'
where 'something' is a pattern that will match the desired record.
