Query

The Query activity retrieves the entries that match the filter string or criteria specified in the datagrid table. Before using the Query activity, you must supply a filter string as an argument. This filter specifies the content of the query, that is, criteria for selecting a subset of rows from the table.

General

In the General tab, you can specify the activity name and a table connection.

The following table describes the fields in the General tab of the Query activity:

Field Module Property? Description
Name No Specifies the name to be displayed as the label for the activity in the process.
Table Connection Yes Click to select a table connection.

If the datagrid for the required table connection is not found, in the Select FireflyResource Resource Template dialog box that opens, click Create Shared Resource to create a datagrid connection first. See Creating a DataGrid and Adding a Table for details.
