Set allow polybase export configuration option

[!INCLUDE sqlserver2016]

The allow polybase export server configuration option allows the export of data out of SQL Server. The functionality of this configuration option is different starting with [!INCLUDEsssql22-md] compared to previous versions:

• Introduced in [!INCLUDEsssql22-md], the CREATE EXTERNAL TABLE AS SELECT (CETAS) statement requires the option allow polybase export to be enabled by using sp_configure. This allows for data to be exported to a CSV or Parquet file. For examples, see Use CREATE EXTERNAL TABLE AS SELECT exporting data as parquet.
• In previous versions of SQL Server, enabling allow polybase export allows HADOOP to export data out of SQL Server to an external table. For more information, see PolyBase connectors and Export data.

The possible values are described in the following table:

Value	Meaning
0	Disabled, the default setting.
1	Enabled

This change takes effect immediately.

Example

The following example enables this setting.

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'allow polybase export', 1;
GO
RECONFIGURE;
GO
