U can do this with simple UDF

Assume a as the current date in format yyyy/dd/mm

public String check_condition(String a,Container container)
{
String b;
if(condition)
 {
     //steps to be performed
 }
else 
{
 b = a.substring(2,4) + "/" + a.substring(8,10);
 return b;
}

}

Hi,

couldn't you return the boolean value of your udf to a standard if-function.

UDF -> if true

then: currentDate

else: currentDate -> Transformation(yyyy/dd/mm, yy/mm)

You can customize the UDF..This UDF i wrote to check a condition....

the code is input value a

for(i=0;i<a.length;i++)

{

if(a.equals("A"))

{

result.addValue("Valid Value");

}

else

{

result.addValue("Not a Valid Value");

}

}

HI

the UDF

java.util.Date d = new java.util.Date();

java.text.SimpleDateFormat f

= new java.text.SimpleDateFormat("yyyy-dd-MM");

return f.format(d) ;

else ......

yy/mm format..
