◆ compareTables()

TYPO3\CMS\Core\Database\Schema\Comparator::compareTables	(	Table	$oldTable,
		Table	$newTable
	)

Returns the difference between the tables $fromTable and $toTable.

If there are no differences this method returns the boolean false.

◆ doctrineDbalMajorThreeDiffColumn()

string [] TYPO3\CMS\Core\Database\Schema\Comparator::doctrineDbalMajorThreeDiffColumn	(	Column	$column1,
		Column	$column2
	)

Returns the difference between the columns

If there are differences this method returns the changed properties as a string array, otherwise an empty array gets returned.

Deprecated:: ‪Use {

See also: ‪columnsEqual()} instead.

Returns: ‪string[]

Note: cloned from doctrine/dbal 3.7.1

◆ typo3DiffColumn()

TYPO3\CMS\Core\Database\Schema\Comparator::typo3DiffColumn	(	Column	$column1,
		Column	$column2
	)

Returns the difference between the columns $column1 and $column2 by first checking the doctrine diffColumn. Extend the Doctrine method by taking into account MySQL TINY/MEDIUM/LONG type variants.

Todo:: ‪Move the column length override for MariaDB/MySQL to the extended platform classes, when the the workaround here can be removed and `AbstractPlatform::columnsEqual() used. Currently blocked by the used Comparator::doctrineDbalMajorThreeDiffColumn() code which compares differently than the new platform code of doctrine. See the todo regarding the platform options in that method.
