Azure SQL Database
Azure SQL Managed Instance
Azure Synapse Analytics
Analytics Platform System (PDW)
Important
The SQL Server Native Client (often abbreviated SNAC) has been removed from SQL Server 2022 (16.x) and SQL Server Management Studio 19 (SSMS). Both the SQL Server Native Client OLE DB provider (SQLNCLI or SQLNCLI11) and the legacy Microsoft OLE DB Provider for SQL Server (SQLOLEDB) are not recommended for new development. Switch to the new Microsoft OLE DB Driver (MSOLEDBSQL) for SQL Server going forward.
The IRowsetFastLoad interface exposes support for SQL Server memory-based bulk-copy operations. SQL Server Native Client OLE DB provider consumers use the interface to rapidly add data to an existing SQL Server table.
If you set SSPROP_ENABLEFASTLOAD to VARIANT_TRUE for a session, you cannot read data from rowsets subsequently returned from that session. When SSPROP_ENABLEFASTLOAD is set to VARIANT_TRUE, all rowsets created on the session will be of type IRowsetFastLoad. IRowsetFastLoad rowsets do not support rowset fetch functionality; therefore, data from these rowsets cannot be read.
