在 Hive 中，if(field1=field2=field3=0,'0','1') 未给出预期结果

Question

In Hive query, in the single IF condition, I provided multiple fields check, but not giving the expected results.

Query:

select ID, field1, field2, field3, 
       if(field1=field2=field3=0,'0','1') as compare_check
from input_table;

input_table

Output results:

Answer 1

Multiple conditions wont work here. Could you please separate all conditions? Also make sure all fields doesn't have any extra space etc. around them.

if(field1=field2 and field1=field3 
and field1=0,'0','1')

There is another way to do it -

If (field1+field2+field3=0,0,1)
