If the input view is defined, then the WHERE clause can substitute incoming values for a given expression.

Valid JSON paths that are defined in the WHERE clause for queries or statements are substituted with values from an incoming document. If the document is missing a value to be substituted into the query or statement documents, it is written to the error view.

The executed query result. 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.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab:

• Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.
