How to write a query that can find me all item_number start with a certain value ?
For instance there are item_numbers like these :
123_abc
123_xyz
ierireire
321_add
999_pop
My current query looks like this :
"select from "+PayPal_Message.class.getName()+" where item_number == '"+Item_Number+"' order by item_number desc"
What's a query look like that can return all item_numbers start with "123_" ?
