SADataAdapter: Insert Rows using Update

C# SADataAdapter Insert Example

The example fetches the Departments table into a DataTable using the SelectCommand property and the Fill method of the SADataAdapter. It then adds two new rows to the DataTable and updates the Departments table from the DataTable using the InsertCommand property and the Update method of the SADataAdapter.

SAConnection conn = new SAConnection( "Data Source=Sybase IQ Demo" );
conn.Open();
SACommand deleteCmd = new SACommand(
    "DELETE FROM Departments WHERE DepartmentID >= 600", conn);
deleteCmd.ExecuteNonQuery();

SADataAdapter da = new SADataAdapter();
da.MissingMappingAction = MissingMappingAction.Passthrough;
da.MissingSchemaAction = MissingSchemaAction.Add;
da.SelectCommand = new SACommand(
    "SELECT * FROM Departments", conn );
da.InsertCommand = new SACommand(
    "INSERT INTO Departments( DepartmentID, DepartmentName ) " +
    "VALUES( ?, ? )", conn );
da.InsertCommand.UpdatedRowSource =
    UpdateRowSource.None;

SAParameter parm = new SAParameter();
parm.SADbType = SADbType.Integer;
parm.SourceColumn = "DepartmentID";
parm.SourceVersion = DataRowVersion.Current;
da.InsertCommand.Parameters.Add( parm );

parm = new SAParameter();
parm.SADbType = SADbType.Char;
parm.SourceColumn = "DepartmentName";
parm.SourceVersion = DataRowVersion.Current;
da.InsertCommand.Parameters.Add( parm );

DataTable dataTable = new DataTable( "Departments" );
int rowCount = da.Fill( dataTable );

DataRow row1 = dataTable.NewRow();
row1[0] = 600;
row1[1] = "Eastern Sales";
dataTable.Rows.Add( row1 );

DataRow row2 = dataTable.NewRow();
row2[0] = 700;
row2[1] = "Western Sales";
dataTable.Rows.Add( row2 );

rowCount = da.Update( dataTable );

dataTable.Clear();
rowCount = da.Fill( dataTable );
conn.Close();
dataGridView1.DataSource = dataTable;
