BufferColumn 结构
Provides read-only metadata for a PipelineBuffer column.
此 API 不符合 CLS。
命名空间: Microsoft.SqlServer.Dts.Pipeline
程序集: Microsoft.SqlServer.PipelineHost(在 Microsoft.SqlServer.PipelineHost.dll 中)
语法
声明
<CLSCompliantAttribute(False)> _
Public Structure BufferColumn
用法
Dim instance As BufferColumn
[CLSCompliantAttribute(false)]
public struct BufferColumn
[CLSCompliantAttribute(false)]
public value class BufferColumn
[<SealedAttribute>]
[<CLSCompliantAttribute(false)>]
type BufferColumn = struct end
JScript 支持使用结构,但不支持声明新结构。
BufferColumn 类型公开以下成员。
