So I have some code like this:
DataSet dataSet = new DataSet();
DataTable dataTable1 = new DataTable("Table1");
DataTable dataTable2 = new DataTable("Table2");
DataTable dataTable3 = new DataTable("Table3");
DataTable dataTable4 = new DataTable("Table4");
dataSet.Tables.Add(dataTable1);
dataSet.Tables.Add(dataTable2);
dataSet.Tables.Add(dataTable3);
dataSet.Tables.Add(dataTable4);
SqlDataAdapter dataAdapter1 = new SqlDataAdapter("SELECT * FROM Table1 WHERE ID = 1", sqlConnection);
SqlDataAdapter dataAdapter2 = new SqlDataAdapter("SELECT Column1, Column2, Column3 FROM Table2", sqlConnection);
SqlDataAdapter dataAdapter3 = new SqlDataAdapter("SELECT Column1, Column2, Column3 FROM Table3", sqlConnection);
SqlDataAdapter dataAdapter4 = new SqlDataAdapter("SELECT Column1, Column2, Column3 FROM Table4", sqlConnection);
SqlCommandBuilder commandBuilder1 = new SqlCommandBuilder(dataAdapter1);
SqlCommandBuilder commandBuilder2 = new SqlCommandBuilder(dataAdapter2);
SqlCommandBuilder commandBuilder3 = new SqlCommandBuilder(dataAdapter3);
SqlCommandBuilder commandBuilder4 = new SqlCommandBuilder(dataAdapter4);
dataAdapter1.Fill(dataTable1);
dataAdapter2.FillSchema(dataTable2, SchemaType.Source);
dataAdapter3.FillSchema(dataTable3, SchemaType.Source);
dataAdapter4.FillSchema(dataTable4, SchemaType.Source);
//do a bunch of code that updates the one row from Table1
//and adds lots of new rows to Table2, Table3, Table4
dataAdapter1.Update(dataTable1);
dataAdapter2.Update(dataTable2);
dataAdapter3.Update(dataTable3);
dataAdapter4.Update(dataTable4);
dataSet.AcceptChanges();
Is there anyway to make this a lot simpler? What would happen if the computer crashed on the line after "dataAdapter2.Update(dataTable2);"? I would like to be able to somehow use just one Update call to update everything. Is that possible?
Also, is this even the best way to do this? With "this" being creating a bunch of new rows in multiple tables depending on what is in one specific row in one specific table.
