MySQL、内部結合を使用した更新クエリが暗黙的に失敗する

Question

内部結合を使用した同様の選択クエリが完全に機能する間、内部結合を使用したMySQLクエリ更新が動作しません。

ワーキングSELECTクエリ

SELECT fa.tax_rate, efa.entity_id 
FROM water_civicrmv2.civicrm_financial_account as fa 
    INNER JOIN water_civicrmv2.civicrm_entity_financial_account efa ON efa.financial_account_id = fa.id 
    INNER JOIN water_civicrmv2.civicrm_option_value cov ON cov.value = efa.account_relationship 
    INNER JOIN water_civicrmv2.civicrm_option_group cog ON cog.id = cov.option_group_id 
    WHERE efa.entity_table = 'civicrm_financial_type' 
    AND cov.name = 'Sales Tax Account is' 
    AND cog.name = 'account_relationship' 
    AND fa.is_active = 1 

失敗しましたUPDATEクエリ

UPDATE water_civicrmv2.civicrm_financial_account as fa 
    INNER JOIN water_civicrmv2.civicrm_entity_financial_account efa ON efa.financial_account_id = fa.id 
    INNER JOIN water_civicrmv2.civicrm_option_value cov ON cov.value = efa.account_relationship 
    INNER JOIN water_civicrmv2.civicrm_option_group cog ON cog.id = cov.option_group_id 
    SET fa.tax_rate = '123123' 
    WHERE efa.entity_table = 'civicrm_financial_type' 
    AND cov.name = 'Sales Tax Account is' 
    AND cog.name = 'account_relationship' 
    AND fa.is_active = 1 

何の構文エラーがないとして、それは静かに失敗した理由を、私は本当に知らない、ただ何も起こりません。

UPDATEのオブジェクトは、単一のテーブルwater_civicrmv2.civicrm_financial_accountあるように、あなたの更新SQLを変更し

：

UPDATE water_civicrmv2.civicrm_financial_account as fa 
    SET fa.tax_rate = '123123' 
    WHERE fa.id = 
      (SELECT fa.id 
      FROM water_civicrmv2.civicrm_entity_financial_account efa 
      INNER JOIN water_civicrmv2.civicrm_option_value cov ON cov.value = efa.account_relationship 
      INNER JOIN water_civicrmv2.civicrm_option_group cog ON cog.id = cov.option_group_id 
      WHERE efa.financial_account_id = fa.id 
       AND efa.entity_table = 'civicrm_financial_type' 
       AND cov.name = 'Sales Tax Account is' 
       AND cog.name = 'account_relationship' 
       AND fa.is_active = 1)
