语法

声明
Function GetDataByRef ( _
    <InAttribute> hRow As Integer, _
    <InAttribute> hCol As Integer _
) As DTP_VARIANT

DTP_VARIANT GetDataByRef (
    [InAttribute] int hRow,
    [InAttribute] int hCol
)

DTP_VARIANT GetDataByRef (
    [InAttribute] int hRow, 
    [InAttribute] int hCol
)

DTP_VARIANT GetDataByRef (
    /** @attribute InAttribute() */ int hRow, 
    /** @attribute InAttribute() */ int hCol
)

function GetDataByRef (
    hRow : int, 
    hCol : int
) : DTP_VARIANT

参数

• hRow
  The handle of the row.

• hCol
  The handle of the column.

返回值

注意：
后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The DTP_VARIANT that contains the data in the column.

备注

This method returns a pointer to the data stored in the column specified by the hCol parameter. This pointer is used to directly modify the data in the column specified by hCol instead of calling the GetData method, modifying the data, and then calling SetData.
