Detailed Description

A set of parameters for GPUdb::getRecordsFromCollection.

Retrieves records from a collection. The operation can optionally return the record IDs which can be used in certain queries such as GPUdb::deleteRecords.

This operation supports paging through the data via the offset and limit parameters.

Note that when using the Java API, it is not possible to retrieve records from join views using this operation. (DEPRECATED)

Constructor & Destructor Documentation

◆ GetRecordsFromCollectionRequest() [1/3]

gpudb::GetRecordsFromCollectionRequest::GetRecordsFromCollectionRequest ( )
inline

Constructs a GetRecordsFromCollectionRequest object with default parameters.

Definition at line 34 of file get_records_from_collection.h.

◆ GetRecordsFromCollectionRequest() [2/3]

gpudb::GetRecordsFromCollectionRequest::GetRecordsFromCollectionRequest ( const std::string &  tableName_,
const int64_t  offset_,
const int64_t  limit_,
const std::map< std::string, std::string > &  options_ 
)
inline

Constructs a GetRecordsFromCollectionRequest object with the specified parameters.

Parameters
[in]tableName_Name of the collection or table from which records are to be retrieved, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing collection or table.
[in]offset_A positive integer indicating the number of initial results to skip (this can be useful for paging through the results). The default value is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT.
[in]limit_A positive integer indicating the maximum number of results to be returned, or END_OF_SET (-9999) to indicate that the maximum number of results allowed by the server should be returned. The number of records returned will never exceed the server's own limit, defined by the max_get_records_size parameter in the server configuration. Use offset_ & limit_ to request subsequent pages of results. The default value is -9999.
[in]options_ The default value is an empty map.
