示例

下面的示例演示如何创建多个SqlMetaData对象,其中介绍了一条记录的列元数据以及创建SqlDataRecordThe following example shows the creation of several SqlMetaData objects, which describe the column metadata of a record, and the creation of a SqlDataRecord. 列的值SqlDataRecord设置和SqlDataRecord发送到调用程序使用SqlContext类。The column values of the SqlDataRecord are set and the SqlDataRecord is sent to the calling program using the SqlContext class.

{
   // Variables.
   SqlMetaData column1Info;
   SqlMetaData column2Info;
   SqlMetaData column3Info;
