How can the update modify the select query results?

To modify the results of a select query, you need to use an update statement. Here are some common methods:

1. Update the table by joining the query result with another table using the update statement and join clause.

UPDATE table1
JOIN table2 ON table1.id = table2.id
SET table1.column = table2.column
WHERE condition;

1. Utilize an update statement and a subquery, use the subquery within the update statement to retrieve the data that needs to be updated. The following example updates the values of a query result into corresponding rows in another table.

UPDATE table1
SET column = (
    SELECT column
    FROM table2
    WHERE condition
)
WHERE condition;

1. By using the UPDATE statement and a temporary table, insert the query results into the temporary table, and then update the data in the target table using the UPDATE statement.

CREATE TEMPORARY TABLE temp_table
SELECT column
FROM table
WHERE condition;

UPDATE table
SET column = (
    SELECT column
    FROM temp_table
)
WHERE condition;

DROP TEMPORARY TABLE temp_table;

Please choose the appropriate method to modify the select query results based on your specific needs.
