Hi Team,

 

I am trying to handle null values using Tmap but getting records whose values are not null.

i have used if else condition but not getting proper output.

For Eg Input data

emp.dat

id|Name|sal

1|AA|100

2|BB|200

3|CC|

OUTPUT

id|Name|sal

1|AA|100

2|BB|200

 

but i need the whole records in parquet format

id|Name|sal

1|AA|100

2|BB|200

3|CC|empty string

 

in tmap i have used for that column if else but null records not coming.

i have attached the file.

@satpaul , you need to use the below way for an empty string. have you used in tmap enable filter in the output section?

possible share you job design.

 

row1.RISK_PCT==null ? "":row1.RISK_PCT
