How does the choice between DATETIME and timestamp data types impact the readability and updateability of date and time values in a MySQL database?
When choosing between DATETIME and timestamp data types in a MySQL database, it's important to consider how each type impacts the readability and updateability of date and time values. DATETIME allows for a wider range of dates and times to be stored, but it requires more storage space and may need additional formatting for readability. On the other hand, timestamp automatically updates when a row is inserted or updated, making it easier to track changes but limiting the range of dates that can be stored.
// Example of using DATETIME data type
$query = "CREATE TABLE example_table (
id INT AUTO_INCREMENT PRIMARY KEY,
event_name VARCHAR(255),
event_date DATETIME
)";
```
```php
// Example of using timestamp data type
$query = "CREATE TABLE example_table (
id INT AUTO_INCREMENT PRIMARY KEY,
event_name VARCHAR(255),
event_date TIMESTAMP
)";
