Returns column filter for the specified event.

命名空间：  Microsoft.SqlServer.Dts.Runtime
程序集：  Microsoft.SqlServer.ManagedDTS（在 Microsoft.SqlServer.ManagedDTS.dll 中）

语法

声明
Public Sub GetColumnFilter ( _
    eventName As String, _
    ByRef columnFilter As DTSEventColumnFilter _
)
用法
Dim instance As LoggingOptions
Dim eventName As String
Dim columnFilter As DTSEventColumnFilter

instance.GetColumnFilter(eventName, columnFilter)

public void GetColumnFilter(
    string eventName,
    ref DTSEventColumnFilter columnFilter
)

public:
void GetColumnFilter(
    String^ eventName, 
    DTSEventColumnFilter% columnFilter
)

member GetColumnFilter : 
        eventName:string * 
        columnFilter:DTSEventColumnFilter byref -> unit 

public function GetColumnFilter(
    eventName : String, 
    columnFilter : DTSEventColumnFilter
)

参数

• eventName
  类型：System. . :: . .String
  The name of the event whose columns you want to control.

• columnFilter
  类型：Microsoft.SqlServer.Dts.Runtime. . :: . .DTSEventColumnFilter%
  A DTSEventColumnFilter with values set to true or false, depending on if the column is included (true) or excluded (false).

示例

The following code example creates a Package and selects a log provider for it. The code example then sets the fields of the DTSEventColumnFilter to true to include that field in the log, or false to exclude the field from the log. The SetColumnFilter then defines that the fields with a value of true are logged when the package incurs an OnError event. A new DTSEventColumnFilter is created, and filled with the values from the existing filter using GetColumnFilter.
