In the spark, we can't compare decimal with boolean, but can compare decimal
with Null.
```
spark-sql> DESC T1;
c1 decimal(10,3)
spark-sql> select * from t1 where c1 in(NULL);
Time taken: 0.082 seconds
```
```
spark-sql> select * from t1 where c1 in(CAST(NULL AS BOOLEAN));
Error in query: cannot resolve '(spark_catalog.default.t1.c1 IN (CAST(NULL
AS BOOLEAN)))' due to data type mismatch: Arguments must be same type but were:
decimal(10,3) != boolean; line 1 pos 27;
