String to BigDecimal conversion issue

Tasfiahm — Wed, 01 Aug 2018 18:47:42 GMT

I am having a common and simple issue with String to BigDecimal conversion.

Input: string

Output: BigDecimal

column name: Id

Inside t-map I am putting the below code in One2One mapping.

(Id.isEmpty() || Id.equals("")) ? null : new BigDecimal(Id)

I don't see any error in Code view but after running I am seeing the error. I have also tried

(Id.isEmpty() || Id.equals("")) ? null : java.math.BigDecimal(Id)

Execution Error

May be you are getting non numeric values in ID from source like space or alpha numeric.

@Tasfiahm,can you try to run with Debug mode and see the data,which is failing in tMap?

use the below expression should work as default if there is no data issue

Id== null || "".equals(Id)?null : new BigDecimal(Id)

You are exactly right. As the data was coming as a string, it was also coming with space, so I have to trim the row before applying the BigInt conversation.
