### Table: Data Overview This table, labeled as "table1," is structured into three columns: `cod1`, `val1`, and `val2`. Below is a detailed transcription of the data entries: | cod1 | val1 | val2 | |------|------|------| | 10 | 10 | 8 | | 12 | 10 | 6 | | 21 | 11 | 15 | | 33 | 10 | 2 | | 41 | 9 | 11 | | 8 | 10 | 6 | | 14 | 9 | 5 | | 11 | 11 | 4 | ### Description - **Columns:** - **cod1**: Represents a series of numerical codes or identifiers. - **val1**: Corresponds to a set of values associated with each `cod1`. - **val2**: Contains another set of values possibly related or compared to `val1`. ### Analysis - The `val1` and `val2` columns present numerical data that could be used for statistical analysis, comparison, or other educational purposes. - The data is laid out to possibly identify trends, relationships, or patterns between the values across different `cod1` entries.

What is the result of the query below? ```sql SELECT * FROM table1 WHERE val1 IN (SELECT val1 FROM table1 WHERE val2 = (SELECT MAX(val2) FROM table1)); ``` ### Explanation: This SQL query retrieves all rows from `table1` where the column `val1` matches the `val1` of rows that have the maximum value of `val2` in the same table. It is a nested query, where: 1. **Inner-most Query**: `(SELECT MAX(val2) FROM table1)` finds the maximum value in the `val2` column. 2. **Middle Query**: `SELECT val1 FROM table1 WHERE val2 = (result of the inner-most query)` retrieves `val1` from rows with the maximum `val2`. 3. **Outer Query**: `SELECT * FROM table1 WHERE val1 IN (result of the middle query)` selects all columns for rows where `val1` matches the result from the middle query.
