SqlMetaData Class

Note: This class is new in the .NET Framework version 2.0.

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)

'Declaration
Public NotInheritable Class SqlMetaData
'Usage
Dim instance As SqlMetaData

public final class SqlMetaData
public final 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 Shared Sub CreateNewRecord()

   ' Variables.
   Dim column1Info As SqlMetaData 
   Dim column2Info As SqlMetaData
   Dim column3Info As SqlMetaData
   Dim record As SqlDataRecord

   ' 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)

End Sub
