I need to update this table in SQL Server with data from its \'parent\' table, see below:
Table: sale
id (int) udid
For SQLite use the RowID property to make the update:
update Table set column = 'NewValue' where RowID = (select t1.RowID from Table t1 join Table2 t2 on t1.JoinField = t2.JoinField where t2.SelectValue = 'FooMyBarPlease');
