In one of my , i discuss about a way to handle a null in your application program by using Null indicator. However this post explain one more way to handle a null by using Scalar function. As you know if my column is defined as NULL and i haven't use any null handling technique in my application program then i may get the error SQL code -305. To avoid this we can use null indicator explained in detail. You can get around this situation by using couple of Scalar function too,which can be part of your SQL query. These Scalar function are VALUE and COALESCE. Both of these function can be used to supply a value whenever DB2 returns a NULL. Let's see how exactly these function works. Example: Let's see i want to select salary of an employees from an EMP table where salary is greater than 1000 and also salary column is defined as NULL. Then i can use the Value function as below. You can put any value instead of 0 here and whenever the SALARY for particular employee is NULL it will be replaced by that default value you placed. The DATA Type of default value you are providing must match with the DATA Type of column SALARY in this case. Simply you can read it as , IF SALARY NOT NULL then SALARY else 0. COALESCE function works the same way as VALUE and have the same syntax. That is COALESCE SALARY,0 Anonymous said... Is there a way to look for empty string instead of null? Like functionX '', 'XYZ' whenever it sees an empty value, it should repalce it with 'ABC'. The requirement here is we store empty string if user does not select a value and in return we display a text whenever a column contains empty string. Now when you sort that column on UI side, it displays the replaced text 'XYZ' on top as on the background, it sees it as ''. What i don't realize is actually how you're not actually a lot more smartly-favored than you might be right now. You understand therefore considerably with regards to this topic, produced me personally imagine it from so many numerous angles. Its like women and men are not involved until it is one thing to accomplish with Girl gaga! Your own stuffs nice. All the time take care of it up! Feel free to visit my weblog; Anonymous said...
