Notes

Datasets

A dataset is a multiple column, multiple row container object. This activity creates and populates a dataset containing a specific set of fields in addition to the standard dataset fields. The table below describes these fields (assuming the name of the created and assigned dataset is theDataset).

Name

Type

Return Value

theDataset.Body

Text

The message body.

theDataset.MD5OfBody

Text

An MD5 digest of the non-URL-encoded message body string (i.e. 1c531e2d189cdcb9ec81ef36f4c22d85). You can use this to verify that SQS received the message correctly.

theDataset.MessageID

Text

An element containing the message ID of the message sent to the queue (i.e. e07cab7e-aa08-469b-aa53-73978906e0bd).

Expressions, Variables and Functions

All text fields allow the use of expressions such as variables, functions or AutoMate extended functions, which can be entered by surrounding the expression in percentage signs (example: %FileDateTime(myVar)% or %myVar%, %Left('Text',2)%). To help construct these expressions, you can open Expression Builder from these fields by clicking the Insert Expression (%) button or by pressing F2.
