Snap type:

Write


Description:

This Snap executes a SQL UPDATE statement for each batch of input documents. Keys from the document will be used as the columns to update and their values will be the updated value in the column.

Note
Updates will be batched up until the account's batch size property or until the structure of the update statement changes. An UPDATE statement will change if an incoming document contains different keys than a previous document.


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 JDBC Account for information on setting up this type of account.


Views:


InputThis Snap has exactly one document input view.
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 update.
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.
