### 1. Minimal reproduce step (Required)

Hi, the following equivalent queries produce inconsistent results:

```
SELECT (((- ((~ ('a')))))AND(TRUE)); -- 1
SET @a = 'a';
PREPARE prepare_query FROM "SELECT (((- ((~ (?)))))AND(TRUE))"; -- BIGINT value is out of range in '-18446744073709551615'
EXECUTE prepare_query USING @a;
```

These two queries have the same results.

The prepared statement triggered an error.
