Detailed Description

template<typename T>
struct gpudb::InsertRecordsRequest< T >

A set of parameters for GPUdb::insertRecords.

Adds multiple records to the specified table. The operation is synchronous, meaning that a response will not be returned until all the records are fully inserted and available. The response payload provides the counts of the number of records actually inserted and/or updated, and can provide the unique identifier of each added record.

The options parameter can be used to customize this function's behavior.

The update_on_existing_pk option specifies the record collision policy for inserting into a table with a primary key, but is ignored if no primary key exists.

The return_record_ids option indicates that the database should return the unique identifiers of inserted records.

Template Parameters

T	The type of object being processed.

Constructor & Destructor Documentation

InsertRecordsRequest() [1/2]

template<typename T >

gpudb::InsertRecordsRequest< T >::InsertRecordsRequest ( )

inline

Constructs an InsertRecordsRequest object with default parameters.

Definition at line 783 of file insert_records.h.

InsertRecordsRequest() [2/2]

template<typename T >

gpudb::InsertRecordsRequest< T >::InsertRecordsRequest ( const std::string &  tableName_, const std::vector< T > &  data_, const std::map< std::string, std::string > &  options_  )

inline

Constructs an InsertRecordsRequest object with the specified parameters.

Parameters

[in]	tableName_	Name of table to which the records are to be added, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
[in]	data_	An array of binary-encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if listEncoding is json.
[in]	options_	Optional parameters. insert_records_update_on_existing_pk: Specifies the record collision policy for inserting into a table with a primary key. If set to true, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be "upserted"). If set to false, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by ignore_existing_pk, allow_partial_batch, & return_individual_errors. If the specified table does not have a primary key, then this option has no effect. Supported values: insert_records_true: Upsert new records when primary keys match existing records insert_records_false: Reject new records when primary keys match existing records The default value is insert_records_false. insert_records_ignore_existing_pk: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when update_on_existing_pk is false). If set to true, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If false, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by allow_partial_batch & return_individual_errors. If the specified table does not have a primary key or if upsert mode is in effect (update_on_existing_pk is true), then this option has no effect. Supported values: insert_records_true: Ignore new records whose primary key values collide with those of existing records insert_records_false: Treat as errors any new records whose primary key values collide with those of existing records The default value is insert_records_false. insert_records_return_record_ids: If true then return the internal record id along for each inserted record. Supported values: insert_records_true insert_records_false The default value is insert_records_false. insert_records_truncate_strings: If set to true, any strings which are too long for their target charN string columns will be truncated to fit. Supported values: insert_records_true insert_records_false The default value is insert_records_false. insert_records_return_individual_errors: If set to true, success will always be returned, and any errors found will be included in the info map. The "bad_record_indices" entry is a comma-separated list of bad records (0-based). And if so, there will also be an "error_N" entry for each record with an error, where N is the index (0-based). Supported values: insert_records_true insert_records_false The default value is insert_records_false. insert_records_allow_partial_batch: If set to true, all correct records will be inserted and incorrect records will be rejected and reported. Otherwise, the entire batch will be rejected if any records are incorrect. Supported values: insert_records_true insert_records_false The default value is insert_records_false. insert_records_dry_run: If set to true, no data will be saved and any errors will be returned. Supported values: insert_records_true insert_records_false The default value is insert_records_false. The default value is an empty map.
