Re: How to handle division by zero error in tmap.

Assuming your expression is .....

row1.col1/row1.col2

...and assuming that if it is divided by 0 you want to return 0 (you can change this to whatever suits you), you can do this....

row1.col1==null || row1.col2==null || row1.col2.equals(0) ? 0 : row1.col1/row1.col2

I am also checking for nulls here, just in case.

Hi @rhall_2_0,

 

I am tried below code,

 

row1.col1==null || row1.col2==null || row1.col2==0 ? 0 : row1.col1/row1.col2

because both are integer column type is integer.

 

It's worked for me.

 

thanks
