How to update and delete data in MySQL
To update data in MySQL, you can use the UPDATE statement. Here is an example of updating data:
UPDATE table_name
SET column1 = value1, column2 = value2
WHERE condition;
table_name is the name of the table to be updated, column1 and column2 are the names of the columns to be updated, value1 and value2 are the values to be updated, and the condition is the criteria for updating the data.
To delete data in MySQL, you can use the DELETE statement. Here is an example of deleting data:
DELETE FROM table_name
WHERE condition;
In this case, table_name is the name of the table to be deleted, and condition is the criteria for deleting data. It is important to note that if there is no condition, all data in the table will be deleted, so the DELETE statement should be used carefully.
