Examples
The following example shows how to create several SqlMetaData objects, which describe the column metadata of a record, and creating a SqlDataRecord. The column values of the SqlDataRecord are set and the SqlDataRecord is sent to the calling program by using the SqlContext class.
//using Microsoft.Data.SqlClient.Server;
[Microsoft.Data.SqlClient.Server.SqlProcedure]
public static void CreateNewRecord()
{
// Variables.
SqlDataRecord record;
// Create a new record with the column metadata. The constructor is
// able to accept a variable number of parameters.
record = new SqlDataRecord(new SqlMetaData[] { new SqlMetaData("Column1", SqlDbType.NVarChar, 12),
new SqlMetaData("Column2", SqlDbType.Int),
new SqlMetaData("Column3", SqlDbType.DateTime) });
// Set the record fields.
record.SetString(0, "Hello World!");
record.SetInt32(1, 42);
record.SetDateTime(2, DateTime.Now);
// Send the record to the calling program.
SqlContext.Pipe.Send(record);
}
Remarks
This class is used together with SqlPipe to send result sets to the client from managed code stored-procedures.
When writing common language runtime (CLR) applications, you should re-use existing SqlDataRecord objects instead of creating new ones every time. Creating many new SqlDataRecord objects could severely deplete memory and adversely affect performance.
