delete_records

GPUdb.delete_records( table_name = None, expressions = None, options = {} )

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) or a single record identified by record_id options. Note that the two selection criteria are mutually exclusive. This operation cannot be run on a collection or 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.
