How to create an entry with MySQL?
If you really, really want to create an entry from within the database (you must have a VERY good reason to do so), then you should create a row in:


entries
elements
elements_sites
content


If you'd like the easier path, use Content migrations. Create a migration, and then add something like:

// Create the entry
$myNewEntry = new craft\elements\Entry();
$myNewEntry-&gt;setFieldValues([
    'title' =&gt; 'My new entry',
    'myCustomFieldHandle' =&gt; 'Look, I can even set a custom field!',
    'myCustomCategoryFieldHandle' =&gt; [$categoryILookedUp-&gt;id],
]);

// Save the entry. Everything else will be handled for you by Craft's API.
Craft::$app-&gt;getElements()-&gt;saveElement($myNewEntry);
