Hello,
I have a bit of a problem, I have looked on the archives and didn't manage
to see anything.
I am trying to write the below function
mail_db=# CREATE FUNCTION "user_id_funct_p2"(varchar)
mail_db-# RETURNS setof varchar AS '
mail_db'# SELECT "mailbox" FROM "user" WHERE "mailbox" LIKE (\'$1%\') '
mail_db-# LANGUAGE sql ;
CREATE
mail_db=# select user_id_funct_p2('test');
user_id_funct_p2
------------------
(0 rows)
If I do
SELECT "mailbox" FROM "user" WHERE "mailbox" LIKE ('test%') ;
It does returns the following results
mailbox
----------
test0001
test0002
test0003
test0004
test0005
test0006
(6 rows)
If I ammed the function to return $1 it does return as test. When I looked @
the debug output it seemed to be matching $1 rather that the value of $1.
That leads me to believe that my character escape sequence is incorrect. I
have tried every possible combination but I am still not returning valid
results.
Many thanks in advance
Mole
