What do you get with the following two type castings:

SELECT coalesce(column_name::integer, 255); ?
SELECT coalesce(column_name, ‘255’::text)::integer; ?

“integer” might actually be “smallint” if you’re only going to 255.

Subject: Pgsql error in coalesce

Hi,
There is table with int4 column. When select query is executed as "select coalesce(column_name, 255), query is failing with below error.
"COALESCE types text and integer cannot be mached".
Any idea?
Thank You!!
