Create Trigger does not replicate in mysql

Question

We created a trigger in the master database but the trigger does not show up in the slave database.

Here is an example of the create trigger:

CREATE TRIGGER filter_pos_transaction_delivery_combo_details BEFORE INSERT ON `pos-transaction_delivery_combo_details`
for each row
begin
    DECLARE msg VARCHAR(200);
    SET @store_code = (SELECT value FROM `admin-settings` WHERE attribute = 'local_store_code' LIMIT 1);

    if STRCMP(new.store_code,@store_code) != 0 then
        if STRCMP( @store_code,'MAINDB') != 0 then
            set msg = "SKIPPING INSERTION: THIS DATA IS NOT FOR THIS LOCAL DB - pos-transaction_delivery_combo_details ";
            SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = msg;
        end if;
    end if;
end;

Here is the cnf configuration:

[mysqld]
user                        = mysql
port                        = 3306
datadir                     = /data/mysql/
pid-file                    = /data/mysql/fusion-maindb.pid
socket                      = /data/mysql/fusion-maindb.sock
log_error                   = /datalog/mysql_error_log/mysql_error.log

Check your binlog format:

When using statement-based replication, triggers on the slave are executed by statements that are executed on the master (and replicated to the slave).

When using row-based replication, triggers are not executed on the slave due to statements that were run on the master and then replicated to the slave. Instead, when using row-based replication, the changes caused by executing the trigger on the master are applied on the slave.
