This failed with the message: User query failed: PROCEDURE imap.user_info can't return a result set in the given context
I thought it was possible to avoid that error by implementing the MySQL procedure in a specific way?..
"Statements that return a result set can be used within a stored procedcure but not within a stored function. This prohibition includes SELECT statements that do not have an INTO var_list clause and other statements such as SHOW, EXPLAIN, and CHECK TABLE."
Sounds like if you used SELECT .. INTO and returned those variables, it would work?
I tried that just now, with my patch not implemented and get the error about 'context' above Unfortunately that does not seem to work.
The SQL that I am using is below, if someone can make it work without my patch I would be grateful.
DROP PROCEDURE IF EXISTS user_pass_check_t !!
CREATE PROCEDURE user_pass_check_t(local_part TEXT, in_domain TEXT, test_pass TEXT) NOT DETERMINISTIC -- login state of the user may change COMMENT "Return user information as needed by dovecot" BEGIN DECLARE usr_addr VARCHAR(128); DECLARE usr_pass VARCHAR(64); DECLARE usr_home VARCHAR(256); DECLARE usr_uid INTEGER; DECLARE usr_gid INTEGER;
SELECT CONCAT(userid, '@', domain), CONCAT('{DIGEST-MD5}', password), home, uid, gid \
INTO usr_addr, usr_pass, usr_home, usr_uid, usr_gid
FROM imap.users WHERE userid = local_part AND domain = in_domain;
SELECT usr_addr AS user, usr_pass AS password, usr_home AS userdb_home, usr_uid AS userdb_uid, usr_gid AS userdb_gid;END !!
