Check if Field Exists (in UDF)?

[Former Member]

Dear All,

Kindly help me with this issue -

In UDF, I want to check whether a field exists or not? I know, this can be done using the standard function EXISTS, but due to some other requirements, I can't use the standard function and need to check the existence functionality within the UDF.

Any help / suggestion will be highly appreciated.

Hi,

you can use this java code,

if("SUPPRESS".equals(ResultList.SUPPRESS)){

result.addValue("1"); //you can put your logic.

}else{

result.addValue("2"); //put your logic here.

}

Thanks,

if (!a.equalsIgnoreCase(ResultList.SUPPRESS)||(!a.equals("")))// if a!=SUPPRESS or a != blank
{
result.addValue(a);// if field exists then this is executed....put ur code here
}

Thanks everyone!!

But I resolved the issue in a different way. I used the EXISTS standard function and played around with the value (true / false) coming out of it, in the UDF.
