How do I write the query?

Question

Display the records between two range I know the nvl function only allows the same data type(ie. number or char or date Nvl(comm, 0)), if commission is null then the text “Not Applicable” want to display, instead of blank space. How do I write the query?

You can use the decode function for the above requirement. Please find the query as below:

 Ex: select ename,DECODE(NVL(comm,0),0,'Not Applicable',comm) from scott.emp;
