[Former Member]

Hi guys,

I have no idea on JAVA, can you please give me one UDF sample for my requirement.

there is one field is getting value on source side A or B or C.

If field value is A - then output value AAAAA

if field value is B - then output vlaue BBBBB

if field value is C - then output value CCCCC

can i write UDF like

String mergeONE(String var1, String var2, String var3, Container container)

{

if (var1 != null)

return var1;

else

if (var2 != null)

return var2;

else

return var3;

}

your input is really great !!

Many thanks

Hi San,

You can achieve this functionality using standard if else functions. You dont need a udf for this.

Hai if you want concatenate value 4 times using UDF

then

String mergeONE(String var1, String var2, String var3, Container container)

{

if (var1 != null)

return var1var1var1var1var1+var1;

else

if (var2 != null)

return var2var2var2var2var2+var2;

else

return var3var3var3var3var3+var3;

}

we can do this using using graphical mapping it self.

Hi San,

Use Fixed Value Mapping from standard functions itself
