Snap type:

Write


Description:

This Snap allows you to execute an SQL delete with the given properties.

If a SELECT query is executed, the query's results are merged into the incoming document and any existing keys will have their values overwritten. On the other hand, the original document is written if there are no results from the query.
 
Expected upstream Snaps:  The dynamic variables used in the execute query can be defined by providing values upstream. The document generator Snaps like JSON Generator can be used upstream. 
Expected downstream Snaps: The Snap will output one document for each execution of Snap with data about number of documents deleted, hence any document processing Snap can be used downstream.


Prerequisites:

[None]


Support and limitations:


Account: 

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See SAP HANA Account for information on setting up this type of account.


Views:


InputThis Snap has exactly one document input view. If the input view is defined, then the where clause can substitute incoming values for a given expression.
OutputThis Snap has at most one document output view. If an output view is available, then the original document that was used to create the statement will be output with the status of the delete executed.
Error

This Snap has at most one document error view and produces zero or more documents in the view.

Note
Database Write Snaps output all records of a batch (as configured in your account settings) to the error view if the write fails during batch processing.
