Post your question to a community of 470,614 developers. It's quick & easy.

Urgent: Input of values (that is, dynamic queries)

How can I execute a query which prompt the user for input?
Something like
SELECT [target list]
FROM Table
WHERE Name=[value input from user]

In Oracle PL/SQL, you use & before variable names to have the SQL*Plus
ask for input.
In Postgres PLpg/SQL, I read that the EXECUTE statement should let you
do something like this, but I tried
EXECUTE 'SELECT * FROM Employeers WHERE id=' || quote_literal(emp_id);
and the psql client tells me
ERROR: syntax error at or near "'SELECT * FROM Employeers WHERE id='"
at character 9
Could you help me, please?
