sql - 查询太复杂？使用追加查询

Question

我已经使用这个追加查询好几天了，它随机抛出这个异常:

Query is too Complex

查询将从联合查询中检索回的数据插入到不同的表中。

INSERT INTO [CA-SSI Dispatch]
SELECT 
SSIQuery.[Phonenumber] AS Phonenumber, 
SSIQuery.[FormRecordNumber] AS FormRecordNumber, 
SSIQuery.[InspectedBY] AS InspectedBY, 
SSIQuery.[Project] AS Project, 
SSIQuery.[DateTimeInspection] AS DateTimeInspection, 
SSIQuery.[Question] AS Question, 
SSIQuery.[Answer] AS Answer, 
SSIQuery.[Rank] AS Rank, 
SSIQuery.[Comment] AS Comment, 
SSIQuery.[Regulation] AS Regulation
FROM SSIQuery

WHERE NOT EXISTS    
(SELECT *    FROM [CA-SSI Dispatch]    WHERE   SSIQuery.[Phonenumber] = [CA-SSI Dispatch].[Phonenumber]    
AND   SSIQuery.[FormRecordNumber] =[CA-SSI Dispatch].[FormRecordNumber]    
AND   SSIQuery.[Project] = [CA-SSI Dispatch].[Project]   
AND   SSIQuery.[DateTimeInspection] = [CA-SSI Dispatch].[DateTimeInspection] 
AND SSIQuery.[Question] = [CA-SSI Dispatch].[Question] 
AND SSIQuery.[Answer] = [CA-SSI Dispatch].[Answer]
AND SSIQuery.[FormRecordNumber] = [CA-SSI Dispatch].[FormRecordNumber]);

在我向联合查询添加更多字段后，INSERT INTO 停止工作并不断返回该错误。如果有帮助，这是我的联合查询的一部分。这个 UNION QUERY，继续工作。

SELECT
SSIAns.phonenumber AS Phonenumber,
SSIAns.Form_Record_Number As FormRecordNumber,
SSIAns.Inspected_By AS InspectedBY,
SSIAns.Project,
SSIAns.Date_Time_of_Inspection AS DateTimeInspection,
QR.q1 AS Question,
SSIAns.Clean_level_ground AS Answer,
SSIRank.Rank_1 AS Rank,
SSIComment.Comment_1 AS Comment,
QR.r1 AS Regulation

FROM SSIAns, SSIRank,SSIComment, QR

WHERE 
SSIRank.Rank_1 = "2_Address_Within_3_Days" AND 
SSIAns.Form_Record_Number=SSIRank.Form_Record_Number 
AND SSIRank.Form_Record_Number =SSIComment.Form_Record_Number

UNION 
SELECT
SSIAns.phonenumber AS Phonenumber,
SSIAns.Form_Record_Number As FormRecordNumber,
SSIAns.Inspected_By AS InspectedBY,
SSIAns.Project,
SSIAns.Date_Time_of_Inspection AS DateTimeInspection,
QR.q2 AS Question,
SSIAns.Adequate_ramps_barricading AS Answer,
SSIRank.Rank_2 AS Rank,
SSIComment.Comment_2 AS Comment,
QR.r1 AS Regulation

FROM SSIAns, SSIRank,SSIComment, QR

WHERE 
SSIRank.Rank_2 = "2_Address_Within_3_Days" AND 
SSIAns.Form_Record_Number=SSIRank.Form_Record_Number 
AND SSIRank.Form_Record_Number =SSIComment.Form_Record_Number

联合查询对下一个相应的字段进行一遍又一遍。例如:rank_3、rank_4 等

两个查询都运行良好，直到我加起来直到第 50 个

UNION 
SELECT
SSIAns.phonenumber AS Phonenumber,
SSIAns.Form_Record_Number As FormRecordNumber,
SSIAns.Inspected_By AS InspectedBY,
SSIAns.Project,
SSIAns.Date_Time_of_Inspection AS DateTimeInspection,
QR.q2 AS Question,
SSIAns.Adequate_ramps_barricading AS Answer,
SSIRank.Rank_50 AS Rank,
SSIComment.Comment_50 AS Comment,
QR.r1 AS Regulation

FROM SSIAns, SSIRank,SSIComment, QR

WHERE 
SSIRank.Rank_50 = "2_Address_Within_3_Days" AND 
SSIAns.Form_Record_Number=SSIRank.Form_Record_Number 
AND SSIRank.Form_Record_Number =SSIComment.Form_Record_Number

现在，只有联合查询有效，当我尝试运行 INSERT INTO 查询以插入辅助表时，我运行错误“查询太复杂”通过联合查询，我们试图将问题分解为相应的答案、排名和评论，并合并到一条记录中。所以问题 1 & 相应的字段是一条记录。问题 2 & 相应的字段是不同的记录。

Answer 1

看起来您将表 QR 添加到您的查询中，但没有将其加入任何可能导致错误的内容。

在 were 子句中，您需要使 QR 表字段等于另一个表，以便将其连接在一起并拉入查询。

这一切都是次要的，首先也是最重要的是将您的代码标准化为使用连接而不是“FROM table1，table2，table3)”的方法

相反，您想这样做: 从表 1 内部连接表 2 ON table1.column1 = TABLE2.column1

等...

如果您提供完整的模式以及表的外键和主键，我可以给您一个准确的答案。
