If the columns in your database have been randomly indexed, you can update them using SQL queries or using a database management tool like phpMyAdmin.
To update a single column, you can use the following SQL query:
UPDATE tablename SET columnname = 'newvalue' WHERE id = 123;
In this example, tablename is the name of the table, columnname is the name of the column you want to update, newvalue is the new value you want to set for that column, and id is the unique identifier of the row you want to update.
If you want to update multiple columns, you can use a similar query with multiple column names and values:
UPDATE tablename SET column1 = 'newvalue1', column2 = 'newvalue2' WHERE id = 123;
If you prefer to use a database management tool, you can log in to phpMyAdmin and navigate to the table and column you want to update. Then, click on the "Edit" button next to the row you want to update and make your changes in the form. Finally, click on the "Save" button to update the row.
