ForEachEnumeratorHostClass.Validate 方法

此 API 支持 SQL Server 2012 基础结构，但不能通过代码直接使用。

Allows the host to determine if there are invalid settings that will prevent the ForEachItemEnumeratorClass from executing successfully.

参数

• pConnections
  类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSConnections100
  A collection of connections used by the ForEachItemEnumeratorClass.

• pVariableDispenser
  类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariableDispenser100
  A IDTSVariableDispenser100 object for locking variables.

• pEvents
  类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSInfoEvents100
  An object that implements the IDTSInfoEvents100 interface.

• pLog
  类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSLogging100
  An object that implements the IDTSLogging100 interface.

返回值

类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.DTSExecResult
A DTSExecResult enumeration that indicates the outcome of the validation.

实现

IDTSForEachEnumerator100.Validate(IDTSConnections100, IDTSVariableDispenser100, IDTSInfoEvents100, IDTSLogging100)
