Server-Side Bindings - Data Source Properties

Expressions defined in the data source are evaluated on the server, using the server-side evaluation context that includes the following objects:

  • user : includes all properties of the current user account, as well as properties of the employee record associated with the user.
  • sql : object that can format date, time, and timestamp values according to the current database and/or current date and time
  • parameters : provides access to all input parameters of the workflow rule that evaluates the expression (typically this is a standard workflow rule, but the client-side UI controls can pass arbitrary additional parameters to standard workflow rules).
Examples:

The parsed restriction defined in the data source uses the current date:

<clause name="wr.date_est_complete" op="&lt;=" value="${sql.currentDate}"/>


The SQL query defined in the data source includes the current user employee ID:

<sql>SELECT...FROM...WHERE wr.requestor = ${user.employee.id}</sql>


The SQL query defined in the data source includes the date literal:

<sql>SELECT...FROM...WHERE wr.date_requested = ${sql.date('2007-01-01')}</sql>


The SQL query defined in the data source includes the WFR parameter sent from the client:

<sql>SELECT...FROM...WHERE wr.status IN ${parameters['status_codes']}</sql>


The following data source properties can contain binding expressions:

  • SQL query text
  • SQL restriction text (for restrictions defined in AXVW and restrictions sent from the client);
  • Parsed restriction values (for restrictions defined in AXVW and restrictions sent from the client
  • Default field values.

Binding expressions in data source properties are evaluated when a workflow rule is called (at request time, or when scheduled rule is executed).
