Hi all,
I was trying to create function in postgres, but it returns error mentioning the language is NOT defined.
The function is as following:
CREATE OR REPLACE FUNCTION test_word_count(TEXT, TEXT) RETURNS INTEGER AS $$
DECLARE
d_word ALIAS FOR $1;
d_phrase ALIAS FOR $2;
BEGIN
IF d_word IS NULL OR d_phrase IS NULL THEN RETURN 0;
RETURN 1;
END;
$$ LANGUAGE plpgsql;
ERROR: language "plpgsql" does not exist
HINT: Use CREATE LANGUAGE to load the language into the database.
I was wonderring why it is not included by default? Or have I missed out something in the configuration!
Also, how to do a better text search? I have come across the bad performance of LIKE statement.
All helps are appreciated.
Thanks.
