Use this Snap to add the LIMIT clause to the incoming SQL query. The LIMIT clause sets an upper limit on the number of records returned by the SQL query. Additionally, you can also specify an offset value so that the Snap displays the records from the specified offset value up to the number of records based on the specified limit. This Snap also allows you to preview the result of the output query. You can validate the modified query using this preview functionality.
