How to modify data in a table in mysql?

To change data in a MySQL table, you can use the UPDATE statement. Here are some examples:

1. Update a single row of data.
2. Update the table with new values for column 1 and column 2 where the condition is met.
3. Update multiple rows of data.
4. UPDATE table_name SET column_name1=new_value1, column_name2=new_value2 WHERE condition;
5. Update all rows of data.
6. Update the table with new values for columns 1 and 2.

Please replace the “table name” in the example above with the actual name of the table you want to update, replace “column name” with the actual name of the column you want to update, replace “new value” with the actual value you want to update to, and replace “condition” with the actual condition to be met.

Before executing the UPDATE statement, make sure you have sufficient authorization and perform a proper backup before updating the data.
