To retrieve both read and unread rows in MySQL, you can add a field in the table to keep track of the read status of a row. For example, you can add a column named "read_status" and set its default value to 0 for unread rows and 1 for read rows.
To retrieve unread rows, you can use a SELECT statement with a WHERE clause to filter rows where "read_status" equals 0:
SELECT * FROM your_table WHERE read_status = 0;
To retrieve read rows, you can use a similar SELECT statement with a WHERE clause to filter rows where "read_status" equals 1:
SELECT * FROM your_table WHERE read_status = 1;
You can also combine both queries to retrieve all rows:
SELECT * FROM your_table;
This will return all rows, including those that are read and unread.
