Hi,
I am new to postgresql and to this moment I am using oracle.
I use posgresql 7.1.2
I try to create very simple ( from doc. examples ) trigger:
CREATE FUNCTION add_one (integer) RETURNS INTEGER AS '
BEGIN
RETURN $1 + 1;
END;
' LANGUAGE 'pgsql';
But the system report:
ERROR: Unrecognized language specified in a CREATE FUNCTION: 'pgsql'.
Recognized languages are sql, C, internal, and created procedural
languages.
I readet in documentation that pgsql is good solution for SP.
Where is the problem?
Many thanks in advance.
