保存数据库错误时的 TYPO3 自定义内容字段

Question

I added some content Fields which looks as it follows;

$temporaryColumnHC = array(
    'my_type' => array(
        'exclude' => 0,
        'label'   => 'My Type',
        'config' => array(
            'type' => 'select',
            'renderType' => 'selectSingle',
            'items' => array(
                array('Bar', 'bar'),
                array('Pie', 'pie'),
                array('Donut', 'donut'),
                array('Line', 'line'),
                array('Bar 2', 'bar2'),
                array('Bar 3', 'bar3'),
                array('Bubble', 'bubble'),
            )
        )
    ),

    'my_suffix' => array(
        'exclude' => 0,
        'label'   => 'My Label Suffix',
        'config' => array(
            'type' => 'input',
            'size' => 10,
            'max' => 20
        )
    ),
    'my_source_url' => array(
        'exclude' => 0,
        'label'   => 'Source URL',
        'config' => array(
            'type' => 'input',
            'renderType' => 'inputLink'
        )
    ),
    'my_source' => array(
        'exclude' => 0,
        'label'   => 'Source Text',
        'config' => array(
            'type' => 'text',
            'cols' => 40,
            'rows' => 15
        )
    ),

);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns(
    'tt_content',
    $temporaryColumnHC
);

but on save I get the following error

error  [1620]: Unknown column 'suffix' in 'field list'

What I have to do that this fields is saved in database

As mentioned already as a comment, TYPO3 complains that the column is missing in the Database. Your extension should provide an ext_tables.sql which extends the Database Schema. See https://docs.typo3.org/m/typo3/reference-coreapi/10.4/en-us/ExtensionArchitecture/FilesAndLocations/Index.html#ext-tables-sql for further information.

The file always contains CREATE TABLE statements, which will be converted by TYPO3 do update the schema. Updating the schema can be done through the install tool of TYPO3, or tools like TYPO3 console via command line.
