◆ fullSizes

std::vector<int64_t> gpudb::ShowTableResponse::fullSizes

If get_sizes is true, an array containing the number of records of each corresponding table in tableNames (same values as sizes).

Otherwise, an empty array.

Definition at line 683 of file show_table.h.

◆ info

std::map<std::string, std::string> gpudb::ShowTableResponse::info

Additional information.

Definition at line 715 of file show_table.h.

◆ joinSizes

std::vector<double> gpudb::ShowTableResponse::joinSizes

If get_sizes is true, an array containing the number of unfiltered records in the cross product of the sub-tables of each corresponding join-table in tableNames.

For simple tables, this number will be the same as sizes. For join-tables, this value gives the number of joined-table rows that must be processed by any aggregate functions operating on the table. Otherwise, (if get_sizes is false), an empty array.

Definition at line 696 of file show_table.h.

◆ properties

std::vector<std::map<std::string, std::vector<std::string> > > gpudb::ShowTableResponse::properties

Property maps of the respective tables in tableNames.

Definition at line 444 of file show_table.h.

◆ sizes

std::vector<int64_t> gpudb::ShowTableResponse::sizes

If get_sizes is true, an array containing the number of records of each corresponding table in tableNames.

Otherwise, an empty array.

Definition at line 675 of file show_table.h.

◆ tableDescriptions

std::vector<std::vector<std::string> > gpudb::ShowTableResponse::tableDescriptions

List of descriptions for the respective tables in tableNames.

Supported values:

Definition at line 424 of file show_table.h.

◆ tableName

std::string gpudb::ShowTableResponse::tableName

Value of tableName.

Definition at line 381 of file show_table.h.

◆ tableNames

std::vector<std::string> gpudb::ShowTableResponse::tableNames

If tableName is a table or view, then the single element of the array is tableName.

If tableName is a schema and show_children is set to true, then this array is populated with the names of all tables and views in the given schema; if show_children is false, then this array will only include the schema name itself. If tableName is an empty string, then the array contains the names of all tables in the user's default schema.

Definition at line 397 of file show_table.h.

◆ totalFullSize

int64_t gpudb::ShowTableResponse::totalFullSize

If get_sizes is true, the sum of the elements of fullSizes (same value as totalSize).

Otherwise, -1.

Definition at line 710 of file show_table.h.

◆ totalSize

int64_t gpudb::ShowTableResponse::totalSize

If get_sizes is true, the sum of the elements of sizes.

Otherwise, -1.

Definition at line 703 of file show_table.h.

◆ typeIds

std::vector<std::string> gpudb::ShowTableResponse::typeIds

Type ids of the respective tables in tableNames.

Definition at line 429 of file show_table.h.

◆ typeLabels

std::vector<std::string> gpudb::ShowTableResponse::typeLabels

Type labels of the respective tables in tableNames.

Definition at line 439 of file show_table.h.

◆ typeSchemas

std::vector<std::string> gpudb::ShowTableResponse::typeSchemas

Type schemas of the respective tables in tableNames.
