Parameters

  • command
    Type: System.String

    Command to execute that is specific to the data source.

  • commandType
    Type: System.Int32

    Type of the indicated command, specifying how to interpret the contents of the command parameter.

  • commandTimeout
    Type: System.Int32

    Length of time, in seconds, to block the client before canceling the schema derivation and returning to the caller. A value of zero indicates infinite timeout; value of -1 indicates a provider default.

Return Value

Type: Microsoft.VisualStudio.Data.DataReader
Returns a DataParameter object, which provides a forward-only, read-only stream from the data source.

Remarks

Due to varying orders in which data and parameter values can be returned by a data source, any out or return value parameters specified in the parameters array of DataParameter objects can be retrieved only after the returned DataReader has been closed.
