Is there any substitute for ifnull()


I have a query for mysql where ifnull() is used.i want to convert it into ejb-ql. Problem here is that i dont find any substitute equivalent to ifnull() in ejb.

For eg:

ifnull(columnname,' ') as newcoulmn

Solution

  • You may try

      coalesce(columnname, ' ') as newcolumn
    

    since coalesce is widely supported function when ifnull is MySql specific one
