Parameters

• command
  Type: System.String

  A command to execute that is specific to a data source.

• commandType
  Type: Microsoft.VisualStudio.Data.Services.SupportEntities.DataCommandType

  A value from the DataCommandType enumeration representing the command type for the indicated command, specifying how to interpret the contents of the command parameter.

• parameters
  Type: array<Microsoft.VisualStudio.Data.Services.SupportEntities.IVsDataParameter[]

  An array of DataParameter objects for the specified command type. While this is an input parameter, the DDEX provider is still able to set properties on individual out and return value parameters.

• commandTimeout
  Type: System.Int32

  The length of time, in seconds, to block the client before canceling the execution and returning to the caller. A value of 0 indicates infinite time-out; a value of -1 indicates a provider default.

Return Value

Type: Microsoft.VisualStudio.Data.Services.SupportEntities.IVsDataReader
An IVsDataReader object, which provides a forward-only, read-only stream from the data source.
