/delete/records

URL: https://<aws.fqdn>/<aws.cluster.name>/gpudb-0/delete/records

Deletes record(s) matching the provided criteria from the given table. The record selection criteria can either be one or more input parameter expressions (matching multiple records), a single record identified by record_id options, or all records when using delete_all_records. Note that the three selection criteria are mutually exclusive. This operation cannot be run on a view. The operation is synchronous meaning that a response will not be available until the request is completely processed and all the matching records are deleted.

Input Parameter Description
