[SR-Users] msilo

[Daniel-Constantin Mierla]

Hello,

you can select all the record in the database for a user with
sql_query() and do a while on $dbr(...) container -- se the example in
the readme of the sqlops module. Also, you must select only the records
for the user that registers at that moment, otherwise you sent the
records for other users -- so you must have some WHERE in the SELECT
statement.

Also, when delivered successfully, you should delete the record from
database -- an event_route can be executed by uac module in such case
and can be used to implement the deletion.

Cheers,
Daniel
