/delete/records

URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/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 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.

Input Parameter Description

Name Type Description
table_name string Name of the table from which to delete records. The set must be a currently existing table and not a collection or a view.
expressions array of strings A list of the actual predicates, one for each select; format should follow the guidelines provided here. Specifying one or more input parameter expressions is mutually exclusive to specifying record_id in the input parameter options.
options map of string to strings

Optional parameters. The default value is an empty map ( {} ).

Supported Parameters (keys) Parameter Description
global_expression An optional global expression to reduce the search space of the input parameter expressions. The default value is ''.
record_id A record ID identifying a single record, obtained at the time of insertion of the record or by calling /get/records/fromcollection with the return_record_ids option. This option cannot be used to delete records from replicated tables.
delete_all_records

If set to true, all records in the table will be deleted. If set to false, then the option is effectively ignored. The supported values are:

  • true
  • false
