MySQL "Update command and delete command" | My SQL Tutorial in Malayalam

The UPDATE statement is used to modify the existing records in a table.

MySQL Update Command Syntax
UPDATE `table_name` is the command that tells MySQL to update the data in a table . SET `column_name` = `new_value' are the names and values of the fields to be affected by the update query. Note, when setting the update values, strings data types must be in single quotes.

To delete rows in a MySQL table, use the DELETE FROM statement: DELETE FROM products WHERE product_id=1; The WHERE clause is optional, but you'll usually want it, unless you really want to delete every row from the table.

MySQL DELETE Statement
DELETE FROM table_name WHERE condition;
Example. DELETE FROM Customers WHERE CustomerName='Alfreds Futterkiste';
DELETE FROM table_name;
Example. DELETE FROM Customers;
