Pomembno

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.

In the provider-specific property set DBPROPSET_SQLSERVERDATASOURCEINFO, the SQL Server Native Client OLE DB provider defines the following data source information properties.

Property ID Description
SSPROP_COLUMNLEVELCOLLATION Type: VT_BOOL

R/W: Read

Default: VARIANT_TRUE

Description: Used to determine if column collation is supported.

VARIANT_TRUE: Column level collation is supported.

VARIANT_FALSE: Column level collation is not supported.
SSPROP_UNICODELCID Type: VT_I4 R/W: Read

Description: Unicode locale ID.

This is the locale used for Unicode data sorting.
SSPROP_UNICODECOMPARISONSTYLE Type: VT_I4 R/W: Read

Description: Unicode comparison style.

The sorting options used for Unicode data sorting.

In the provider-specific property set DBPROPSET_SQLSERVERSTREAM, the SQL Server Native Client OLE DB provider defines the following additional property.

Property ID Description
SSPROP_STREAM_XMLROOT Type: VT_BSTR R/W: Read/Write

Description: The result of a FOR XML query may not be a well-formed document. When this property is specified, the result of a 'select ... for XML' query is wrapped in the root tag provided by this property to return a well formed XML document. If the query is executed in the browser it may cause the browser to display parser errors when loading the result. To avoid the error, SQL ISAPI supports the keyword ROOT. This keyword maps to SSPROP_STREAM_XMLROOT property.
