Subject [jira] Commented: (GERONIMO-1206) SQLSecurityRealm doesn't work with PostgreSQL

Vamsavardhana Reddy commented on GERONIMO-1206:
-----------------------------------------------

What happens when an SQL like the following is used? 

(SELECT user, password FROM users WHERE username=?) UNION (SELECT usrnam, pwd FROM moreusers
WHERE usrnam=?)

> The SQLSecurity realm tries to be clever and dynamically discover the number of prepared
statement parameters (?'s) in the queries.  PostgreSQL doesn't support the getParameterMetaData
call this relies upon.  Since this was just a convenience anyway, I'm going to remove the
dynamicness and require that the user and group SQL statements have exactly 1 ? which stands
for the username.  As in:
> SELECT user, password FROM users WHERE username=?
> SELECT user, role FROM user_roles WHERE username=?
