simple UDF

[Former Member]

why do following UDF giving error. It is expecting return statement from else part. I donot want else part of If stmt Iam writing.

<i>public String GroupTest(String a,Container container){

if (a.equals("ExportOne")) return "One";

if (a.equals("ExportTwo")) return "Two";

if (a.equals("ExportThree")) return "Three";</i>

What is problem with above UDF?. I want If statements without else part. Can someone please help me.

Im writing this as part of message splits. So please do not suggest to use fixvalues mapping or something else. I am just looking for multiple if statements without else part.

Thanks

Hi Ram,

Any java function should return some value in ur case as all the return statements are with in IF statement so code will not compile.

So put a dummy return statement at the end.

return " ";

Hi Ram,

the method has to return something in every case so here it is claiming a missing

...
else
 return "something";

Why don't you go for something like:

return a.replaceFirst("Export","");

hi,

can you try this:

if (a.equals("ExportOne"))

{

return "One";

}

else if (a.equals("ExportTwo"))

{

return "Two";

}

else

{

return "nothing";

}

Michal,

thanks but I donot want else part. basically I donot like UDF return 'nothing' as in your example. Any other suggestions?. I want multiple if statements without else part. Thx

Ram,

for the signature of the method it is necessary to return something in any case (ExportFour), so the else is necessary.

Otherwise you can go for the solution I proposed.

ur code should look like

public String GroupTest(String a,Container container){

if (a.equals("ExportOne")) return "One";

if (a.equals("ExportTwo")) return "Two";

if (a.equals("ExportThree")) return "Three";

return " ";

}

Ram,

this is very strange req. that you dont want else stmt

but Kavita's sol will do

try:

if (a.equals("ExportOne")) return "One";

if (a.equals("ExportTwo")) return "Two";

if (a.equals("ExportThree")) return "Three";

return " ";

You guys are awesome. Thank you for quick turnaround. Many of you answered perfectly and the explantion of Kavitha ( First in answering chain ) really helps to find the reason behind not having else part. Thanks again.

Hi Ram,

the problem you are facing is may be because

the input to the udf isnt one of the ExportOne,ExportTwo or ExportThree

please make it sure that you are sending them

otherwise it wo'nt ask for 'else'

and see to it that udf must return something.

Hi,

even before testing the function when I do check mapping its giving me error. i'm giving the same value as shwon in the if statement
