Case When in Flink Table API

[Soheil Pourbafrani]

How can I use the correct way of Case When this example:

myTlb.select(

"o_orderdate.substring(0,4) as o_year,

 volume, 

(when(n_name.like('%BRAZIL%'),volume).else(0)) as case_volume"

)

Flink errors on the line 

(when(n_name.like('%BRAZIL%'),volume).else(0)) as case_volume"
