List pgsql-sql
Please post your complete CREATE FUNCTION statement. Error code 42601 refers to some syntax error which probably occurs just before you start looping. To find it I need to see more code.
Please don't mail me directly. Only mail to pgsql-sql@postgresql.org

They are not working well.

Allways the same error.

(if while)
ERROR: syntax error at or near "WHILE"
SQL state: 42601
Character: 1

(if for)

ERROR: syntax error at or near "FOR"
SQL state: 42601
Character: 1

(if loop)
ERROR: syntax error at or near "LOOP"
SQL state: 42601
Character: 1
I installed the pgsql but I don't think it is a problem of language.
What could be wrong ? I am not using functions too. I am using the SQL
tool of PgAdmin III.

Any help would be glad.
