Re: unable to call a function

something gone wrong the same...

REATE OR REPLACE FUNCTION check_if_if_exist(id integer, table_name
character, table_column character)
RETURNS boolean AS
$BODY$

DECLARE res BOOLEAN;

BEGIN
EXECUTE 'SELECT EXISTS(SELECT * FROM'||table_name||
'WHERE'||table_column||'='||$1||')' INTO res USING id;
RETURN res;
END;

select check_if_exist(10, 'prova', 'identificatore');

RROR: function check_if_exist(integer, unknown, unknown) does not exist
LINE 1: select check_if_exist(10, 'prova', 'identificatore');
^
HINT: No function matches the given name and argument types. You might need
to add explicit type casts.
