Identify Duplicate Records in Customers Table

Question

Find records that are completely identical across all relevant columns.

Accepted Answer

```sql
SELECT name, email, created_at, COUNT(*)
FROM customers
GROUP BY name, email, created_at
HAVING COUNT(*) > 1;
```

This query identifies duplicate records in the "customers" table by grouping rows based on identical values in the "name", "email", and "created_at" columns and returning those that appear more than once.
