How to schedule SMS messages for sending
If you use the SQL-SMS gateway configuration of Ozeki NG SMS Gateway,
you can schedule your SMS message sendings in a very simple way. Scheduling
means that you set a specific date and time for a message to determine when
should it be sent.
Setup scheduled SMS sending (table layout)
To configure this option, first you need to modify your ozekimessageout
table definition to include an extra column for the scheduled delivery
time. You can call this column "scheduledtime". To modify the table
definition issue the following SQL command in an SQL console:
alter table ozekimessageout add column scheduledtime
|
Setup scheduled SMS sending (configure Ozeki NG)
After the table layout has been modified, you need to open the database
user configuration of Ozeki NG. The configuration modification is
simple: you need to modify the SQL query used for selecting messages to
be sent (Figure 1). This can be done by clicking on the "SQL for Sending" tab
of the
SQL user configuration form and changing the "Polling" query to this:
SELECT
id,sender,receiver,msg,msgtype,operator
FROM
ozekimessageout
WHERE
status='send' and scheduledtime<now()
|
Notice the added where condition that will only select messages that
can be sent from the database.

After this is configured, to send a scheduled SMS message all you have
to do is specify the datetime value in the ozekimessagout table.
