Re: Query with Parameters and Wildcards

In the original select you missed a small part. The operation || needs a value
on every side and you missed the value on the left side. You had it as: WHERE
(customerlastname ILIKE || '%') instead of WHERE (customerlastname
ILIKE 'lastname' || '%'). And that is the reason for the error you got.

The function from dayat has a small mistake. It should be:
CREATE OR REPLACE FUNCTION TEST(lastname VARCHAR)
else it will result in an error because of the missing space.
