参数

• connections
  类型：Microsoft.SqlServer.Dts.Runtime.Connections
  A collection of connections used by the task.

• variablesDispenser
  类型：Microsoft.SqlServer.Dts.Runtime.VariableDispenser
  A VariableDispenser object for locking variables.

• events
  类型：Microsoft.SqlServer.Dts.Runtime.IDTSComponentEvents
  An object that implements the IDTSComponentEvents interface.

• log
  类型：Microsoft.SqlServer.Dts.Runtime.IDTSLogging
  An object that implements the IDTSLogging interface.

• txn
  类型：System.Object

返回值

类型：System.Boolean
true indicates that the DMX query task executed successfully; false indicates that the DMX query task execution failed.
