Database Operations

Database Operations allow you to connect to databases and execute queries against them. These operations can be used for applying transformations after a job run, creating a logging system, and much more.

The example below uses the dbNonQuery operation in the Post Job Event to insert a new row that logs the Job results:

<api:info title="After Run" desc="This event is fired after running a job.">
  <input name="JobName"         required="true" desc="The name of the job being executed." />
  <input name="Source"          required="true" desc="The name of source connection." />
  <input name="Destination"     required="true" desc="The name of destination connection." />
  <input name="JobStatus"       required="true" desc="The status of the completed run."/>
  <input name="Query#"          required="true" desc="An array containing each query that was executed." />
  <input name="QueryStatus#"    required="true" desc="An array containing the status of each query that was executed." />
</api:info>

<api:set attr="db.driver"  value="System.Data.SqlClient"/> 
<api:set attr="db.conn"   value="Data Source=sqlserver;Initial Catalog=Test;User ID=user;Password=pass;"/> 
<api:set attr="db.query">
INSERT INTO MyLog (JobName, RunDate, Results) VALUES ('[_input.JobName]', '[null | now()]', '[_input.JobStatus]')
<api:set/>
<api:call op="dbNonQuery" in="db"/>
