I pass the SQL query from a python server to Oracle with double backslashes:

```
SELECT
   ID
FROM
   Works
WHERE
   NAME IN ('ABC\\ABC', 'sdf\\sdfsdf', 'lkj\\sdfsdf')

```

I got nothing after the query was executed. But when remove one backslash and execute in DBeaver (SQL Tool), result is OK.

`NAME` fields in the table have one backslash and look like this: `ABC\ABC`.
