Doctrine\DBAL\Platforms\SQLServerPlatform::getAlterColumnCommentSQL PHP Метод

getAlterColumnCommentSQL() защищенный Метод

SQL Server does not support native column comments, therefore the extended properties functionality is used as a workaround to store them. The property name used to store column comments is "MS_Description" which provides compatibility with SQL Server Management Studio, as column comments are stored in the same property there when specifying a column's "Description" attribute.

protected getAlterColumnCommentSQL ( string $tableName, string $columnName, string $comment ) : string
$tableName	string	The quoted table name to which the column belongs.
$columnName	string	The quoted column name to alter the comment for.
$comment	string	The column's comment.
Результат	string
