Consider the following queries:

{code}
create table user (id int primary key, name varchar);
SELECT CASE WHEN id = 2016 THEN SUM(id) END FROM user GROUP BY id;
{code}

Will cause splitter to try executing wrong SQL:

```Caused by: org.h2.jdbc.JdbcSQLException: Столбец "__Z0.ID" не найден
Column "__Z0.ID" not found; SQL statement:
SELECT
CASE  WHEN (__Z0.ID = 2016) THEN SUM(__C0_0) END __C0_0
FROM PUBLIC.__T0 [42122-197]```
