OPENROWSET (DMX)

Replaces the source data query with a query to an external provider. The INSERT, SELECT FROM PREDICTION JOIN, and SELECT FROM NATURAL PREDICTION JOIN statements support OPENROWSET.

Syntax

OPENROWSET(provider_name,provider_string,query_syntax)

Arguments

  • provider_name
    An OLE DB provider name.

  • provider_string
    The OLE DB connection string for the specified provider.

  • query_syntax
    A query syntax that returns a rowset.

Remarks

The data mining provider will establish a connection to the data source object by using provider_name and provider_string, and will execute the query specified in query_syntax to retrieve the rowset from the source data.

Examples

The following example can be used within a PREDICTION JOIN statement to retrieve data from the AdventureWorks2008R2 database by using a Transact-SQL SELECT statement.
