Question

我在以下查询中收到运行时错误消息3071，指出查询过于复杂。我在过去创建了一些看起来比这个更复杂的查询。我想了解产生此消息的原因：

Answer 1

Possible typo:

...
INNER JOIN tblValueChain02 ON tblValueChain03.IDMacroProcess = tblValueChain02.IDMicroProcesso02)`
...

...perhaps should be IDMacroProcesso (missing "o" at the end of this field)?

Is [tblDependencies01].[ID] a number field? If so, then in your WHERE clause you've used single quotes denoting you're expecting to match a string; so this:

WHERE [tblDependencies01].[ID]= '" & ID & "'"

...should be written like this, if ID is a number:

WHERE [tblDependencies01].[ID]=" & ID

You've referred to most fields in your SELECT clause using the tableName.fieldName convention except for PotSolution (this may not be an issue, but it's good to be consistent!)

Some more things to try if the above doesn't work: http://allenbrowne.com/subquery-02.html#QueryTooComplex
