Connection Property (DbDataTable)
Gets or sets the
System.Data.IDbConnection used to connect to the data source.
Property Value
An
System.Data.IDbConnection object which provides a connection to the data source.
This sample shows how to use
DbDataTable. The routine accepts DbTable-compatible object, IDbCommand implementor object, and IDbConnection implementor object as parameters. After SQL query text has been set the data is retrieved from the table.
public void UseDataTable(DbDataTable myDataTable, DbCommand myCommand, DbConnection myConnection)
{
myDataTable.Connection = myConnection;
myCommand.CommandText = "SELECT * FROM Test.Dept";
myDataTable.SelectCommand = myCommand;
try
{
myDataTable.Active = true;
foreach(DataRow myRow in myDataTable.Rows)
{
foreach(DataColumn myCol in myDataTable.Columns)
{
Console.Write(myRow[myCol]+"\t");
}
Console.WriteLine();
}
}
finally
{
myDataTable.Active = false;
}
}
Public Sub UseDataTable(ByVal myDataTable As DbDataTable, ByVal myCommand As DbCommand, ByVal myConnection As DbConnection)
myDataTable.Connection = myConnection
myCommand.CommandText = "SELECT * FROM Test.Dept"
myDataTable.SelectCommand = myCommand
Try
myDataTable.Active = True
Dim myRow As DataRow
Dim myCol As DataColumn
For Each myRow In myDataTable.Rows
For Each myCol In myDataTable.Columns
Console.Write(myRow(myCol) & Chr(9))
Next myCol
Console.WriteLine()
Next myRow
Finally
myDataTable.Active = False
End Try
End Sub
