「PHP應用程序/控制檯學說：架構：更新--force」給出了一個語法錯誤

Question

，當我在一個symfony項目運行php app/console doctrine:schema:update --force我有一個錯誤，我得到以下錯誤：

[Doctrine\DBAL\DBALException]                                     
An exception occurred while executing 'DROP INDEX idx-id ON extra':                        

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-id ON extra' at line 1 

[Doctrine\DBAL\Driver\Mysqli\MysqliException]                                 
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-id ON extra' at line 1 

這是生成的SQL給出了錯誤：

DROP INDEX idx-id ON extra 

錯誤是索引名不包裹「`」， 我怎麼能得到它，因此指數名稱始終包裹着「`」？

Answer 1

這是一個design decision：

For compatibility reasons between all the supported vendors and edge case problems Doctrine 2 does NOT do automatic identifier quoting. This can lead to problems when trying to get legacy-databases to work with Doctrine 2.

假設你現在讓學說名稱索引時，我的建議是手動重命名（或下降）的指數，然後運行架構更新。
