To update a MySQL database with a condition, you can use the following SQL syntax:

UPDATE table_name SET column_name = new_value WHERE condition;

In this syntax:

• table_name is the name of the table you want to update.
• column_name is the name of the column you want to update.
• new_value is the new value you want to set for the column.
• condition is the condition that must be met for the update to occur. This can be any valid SQL condition, such as WHERE id = 1 or WHERE name = 'John'.

For example, if you wanted to update the email column in a table called users for all users where id is equal to 1, you would use the following SQL:

UPDATE users SET email = 'newemail@example.com' WHERE id = 1;

This will set the email column to 'newemail@example.com' for all rows where id is equal to 1 in the users table.
