Detailed Description

A set of input parameters for const.

Deletes record(s) matching the provided criteria from the given table. The record selection criteria can either be one or more 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.

gpudb::DeleteRecordsRequest::DeleteRecordsRequest ( const std::string &  tableName_, const std::vector< std::string > &  expressions_, const std::map< std::string, std::string > &  options_  )

inline

Constructs a DeleteRecordsRequest object with the specified parameters.

Parameters

[in]	tableName_	Name of the table from which to delete records, in [schema_name.]table_name format, using standard name resolution rules. Must contain the name of an existing table; not applicable to views.
[in]	expressions_	A list of the actual predicates, one for each select; format should follow the guidelines provided here. Specifying one or more expressions is mutually exclusive to specifying record_id in the options.
[in]	options_	Optional parameters. gpudb::delete_records_global_expression: An optional global expression to reduce the search space of the expressions. The default value is ''. gpudb::delete_records_record_id: A record ID identifying a single record, obtained at the time of /insert/records or by calling /get/records/fromcollection with the return_record_ids option. This option cannot be used to delete records from replicated tables. gpudb::delete_records_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. gpudb::delete_records_true gpudb::delete_records_false The default value is gpudb::delete_records_false.
