I am planning to send a prefix before the number and use that prefix in the SQL query to select the CLID. I was thinking in the sqlops to select the CLID and then append the result in the Remote-Party-ID:

modparam("sqlops","sqlcon","cb=>mysql://kamailio:abc@10.10.1.1/testdb")
modparam("sqlops","sqlcon","ca=>dbdriver://username:password@dbhost/dbname")
...

...
sql_query("ca", "select clid from mitable where prefix = $var(prefix)", "ra");
xlog("number of rows in table domain: $dbr(ra=>rows)\n");
sql_result_free("ra");
