TigGetDBProperty is a function, not a procedure in MySQL database so we have to use select to call it:
select TigGetDBProperty('password-encoding');
Most likely output is this:
+---------------------------------------+ | TigGetDBProperty('password-encoding') | +---------------------------------------+ | NULL | +---------------------------------------+ 1 row in set, 1 warning (0.00 sec)
Which means a default password encoding is used, in plain-text and thus no encoding. And we can actually check this in the database directly:
select uid, user_id, user_pw from tig_users where user_id = 'test@example.com';
And expected result with plain-text password format would be:
+-----+--------------------+---------+ | uid | user_id | user_pw | +-----+--------------------+---------+ | 41 | 'test@example.com' | test77 | +-----+--------------------+---------+ 1 row in set (0.00 sec)
