Solution (By Examveda Team)
This question tests your understanding of how to use the WHERE clause in MySQL, specifically when working with numeric data. Let's break down the code and find the error:The Problem
The error lies in the BETWEEN clause for `fed_id`:
```sql AND fed_id BETWEEN 5000-00-000 AND 9999-999-000; ```
MySQL interprets `5000-00-000` and `9999-999-000` as date values because of the hyphens (-) and leading zeros. Since `fed_id` is likely a numeric field (customer ID), this comparison is incorrect.
Solution
To fix the error, we should remove the hyphens and leading zeros from the `BETWEEN` clause:
```sql AND fed_id BETWEEN 5000000 AND 9999999; ```
Explanation
The corrected statement now compares `fed_id` to a numeric range between 5000000 and 9999999.
Answer
The correct answer is Option A: Yes. There is an error in the statement.
