Question

我有兩個表：

rapprovals_tbl 

rId rAssignment rState rApprover rapprovaldt rType rNotes 
    12345678      
1 12345679 Paid 12345678 31/05/2015 18:23 Flex  
5 12345679 Approved 12345678 14/05/2015 18:23 Normal 
6 12345679 Pending   Normal 

timerecord_tbl 

RowID Assignment1 wMonth StartTime EndTime  
1 12345679 Mar-15 17/03/2015 11:29 18/03/2015 16:12 Flex  
5 12345679 Mar-15 17/03/2015 11:00 17/03/2015 12:00 Normal 
6 12345679 Mar-15 17/03/2015 11:50 18/03/2015 16:11 Normal 

我有形式兩個組合框，這兩篇文章，這源工作; 框1 -

Select [staffid] FROM [control_tbl] WHERE [supervisorid] = '12345678' 

專欄2

SELECT timerecord_tbl.[RowID] 
FROM timerecord_tbl 
INNER JOIN rapprovals_tbl ON timerecord_tbl.RowID = rapprovals_tbl.rId 
WHERE (((timerecord_tbl.[Assignment1])='" & Box 1 & "' 
    AND (rapprovals_tbl.[rState] is null) Or (rapprovals_tbl.[rState] = 'Pending'))); 

我想只有那些以箱1個員工記錄專欄2

我如何去了解這個相關的RowID，目前其列出了所有行ID。

我將不勝感激任何幫助。

Answer 1

試着改變你的SQL的框2，像這樣：

SELECT timerecord_tbl.[RowID] 
FROM timerecord_tbl 
INNER JOIN rapprovals_tbl ON timerecord_tbl.RowID = rapprovals_tbl.rId 
WHERE (timerecord_tbl.[Assignment1]='" & Box 1 & "') 
    AND ((rapprovals_tbl.[rState] is null) Or (rapprovals_tbl.[rState] = 'Pending'))); 

我覺得@MarcB在說同樣的事情。您的「OR」語句被應用於整個WHERE子句，而不僅僅是另一個rState過濾器。更改括號將正確分離並修復它。
