SqlMetaData Class

Specifies and retrieves metadata information from parameters and columns of SqlDataRecord objects. This class cannot be inherited.

Namespace:  Microsoft.SqlServer.Server
Assembly:  System.Data (in System.Data.dll)
public sealed class SqlMetaData

The following example shows the creation of several SqlMetaData objects, which describe the column metadata of a record, and the creation of a SqlDataRecord. The column values of the SqlDataRecord are set and the SqlDataRecord is sent to the calling program using the SqlContext class.

[Microsoft.SqlServer.Server.SqlProcedure]
public static void CreateNewRecord()
{
   // Variables.
   SqlMetaData column1Info;
   SqlMetaData column2Info;
   SqlMetaData column3Info;
   SqlDataRecord record;

   // Create the column metadata.
   column1Info = new SqlMetaData("Column1", SqlDbType.NVarChar, 12);
   column2Info = new SqlMetaData("Column2", SqlDbType.Int);
   column3Info = new SqlMetaData("Column3", SqlDbType.DateTime);

   // Create a new record with the column metadata.      
   record = new SqlDataRecord(new SqlMetaData[] { column1Info, 
                                                  column2Info, 
                                                  column3Info });

   // 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);
}
