Automatically generates single-table commands used to reconcile changes made to a
System.Data.DataSet with the SQL Server.
The following example uses
SqlCommand, along with
SqlDataAdapter and
SqlConnection, to select rows from SQL Server. The example is passed an initialized
System.Data.DataSet, a connection string, a query string that is SQL SELECT statement, and a string that is the name of the SQL Server table. The example then creates a
SqlCommandBuilder.
public DataSet SelectSqlSrvRows(DataSet myDataSet,string myConnection,string mySelectQuery,string myTableName)
{
SqlConnection myConn = new SqlConnection(myConnection);
SqlDataAdapter myDataAdapter = new SqlDataAdapter();
myDataAdapter.SelectCommand = new SqlCommand(mySelectQuery, myConn);
SqlCommandBuilder myCommandBuilder = new SqlCommandBuilder(myDataAdapter);
myConn.Open();
DataSet myDataSet = new DataSet();
myDataAdapter.Fill(myDataSet, "Departments");
//code to modify data in dataset here
//Without the SqlCommandBuilder this line would fail
myDataAdapter.Update(myDataSet, "Departments");
myConn.Close();
return myDataSet;
}
Public Function SelectSqlSrvRows(myDataSet As DataSet, myConnection As String, mySelectQuery As String, myTableName As String) As DataSet
Dim myConn As New SqlConnection(myConnection)
Dim myDataAdapter As New SqlDataAdapter()
myDataAdapter.SelectCommand = New SqlCommand(mySelectQuery, myConn)
Dim myCommandBuilder As SqlCommandBuilder = New SqlCommandBuilder(myDataAdapter)
myConn.Open()
Dim myDataSet As DataSet = New DataSet
myDataAdapter.Fill(myDataSet, "Departments")
' Code to modify data in DataSet here
' Without the SqlCommandBuilder this line would fail.
myDataAdapter.Update(myDataSet, "Departments")
myConn.Close()
SelectSqlSrvRows = myDataSet
End Function
