The syntax for the SQL UPDATE statement is:
UPDATE table SET column = expression WHERE predicates;
UPDATE employees SET name = 'Tommy' WHERE name = 'Dev';This SQL UPDATE statement would update all employee names in the employees table from Dev to Tommy.
Updating multiple columns example:
An SQL UPDATE example where you might want to update more than one column with a single SQL UPDATE statement.
UPDATE employees SET name = 'Tom', city = 'Delhi' WHERE name = 'Jack';When you want to update multiple columns, you can do this by separating the column/value pairs with commas.
This SQL UPDATE statement would update the employee name to "Tom" and city to "Delhi" where the name of the employee is "Jack".
