使用mssql后端的经典asp应用程序，但其中一个工具（收集并显示相关的客户和部门发票）将其数据存储在一个小型Jet数据库中。
为了将两者合并为一个记录集，我们创建了一个Access数据库shell，并在其中链接了表元素以关联MSSQL和Access元素。在Web服务器（IIS8）上下载并安装了最新的MS Access驱动程序，调整了标头以扩充应用程序脚本标头中新shell数据库的连接字符串。
经典的asp然后构建查询，我们做一个response.write，将生成的sql复制/粘贴到access和test中，效果很好。
回到Web服务器，它会出现“数据类型不匹配错误”。
我打破了两个子查询来测试来自web服务器配置，并且每个查询分别在web服务器上执行。它们一起在IIS上爆炸，但在粘贴到MS Access SQL窗口时运行正常，没有任何变化。
这是构建查询的经典ASP：
strSQL = "" &_
"SELECT AR.Invoice, AR.Amount, AR.PostingDate, AR.Total, AR.Document, AR.SummaryId, AR.Description, AR.JobNumber, " &_
"AR.Reference, AR.JobDescription, AR.InvoiceDate, AR.Contact, Temps.SumOfQuantity, Temps.Customer " &_
"FROM " &_
"(SELECT ARSummary.Invoice, ARDetail.Amount, ARDetail.PostingDate, ARSummary.Total, ARDetail.Document, ARSummary.SummaryId, " &_
"ARDetail.Description, Orders.JobNumber, Orders.Reference, Orders.JobDescription, ARSummary.InvoiceDate, " &_
"ARCustomers.Contact " &_
"FROM (((ARSummary LEFT JOIN ARCustomers ON ARSummary.Customer = ARCustomers.Customer) " &_
"LEFT JOIN ARDetail ON ARSummary.SummaryId = ARDetail.SummaryId) " &_
"LEFT JOIN ArTerms ON ARCustomers.TermsCode = ArTerms.TermsCode) " &_
"RIGHT JOIN Orders ON ARSummary.Reference = Orders.Reference " &_
"WHERE " & strWhereClause & ") " &_
"AS AR LEFT JOIN " &_
"(SELECT DISTINCT(HistoryDetail.Invoice), Orders.JobNumber, HistoryDetail.Reference, HistoryDetail.InvoiceDate, " &_
"Sum(HistoryDetail.Quantity) AS SumOfQuantity, Customers.Customer " &_
"FROM Orders RIGHT JOIN ((HistoryDetail LEFT JOIN Applicants ON HistoryDetail.AppId = Applicants.ApplicantID) " &_
"LEFT JOIN Customers ON HistoryDetail.Customer = Customers.Customer) ON Orders.Reference = HistoryDetail.Reference " &_
"GROUP BY HistoryDetail.Invoice, Orders.JobNumber, HistoryDetail.Reference, HistoryDetail.InvoiceDate, Customers.Customer " &_
"HAVING " & strHavingClause & ") " &_
"AS Temps " &_
"ON AR.Invoice = Temps.Invoice " &_
" ORDER BY AR.JobNumber, AR.JobDescription, AR.InvoiceDate, Temps.Customer, AR.Invoice"
...以及由脚本构建和输出的结果查询：
SELECT AR.Invoice, AR.Amount, AR.PostingDate, AR.Total, AR.Document, AR.SummaryId, AR.Description, AR.JobNumber, AR.Reference, AR.JobDescription, AR.InvoiceDate, AR.Contact, Temps.SumOfQuantity, Temps.Customer
FROM (
SELECT ARSummary.Invoice, ARDetail.Amount, ARDetail.PostingDate, ARSummary.Total, ARDetail.Document, ARSummary.SummaryId, ARDetail.Description, Orders.JobNumber, Orders.Reference, Orders.JobDescription, ARSummary.InvoiceDate, ARCustomers.Contact FROM
(((ARSummary LEFT JOIN ARCustomers ON ARSummary.Customer = ARCustomers.Customer)
LEFT JOIN ARDetail ON ARSummary.SummaryId = ARDetail.SummaryId)
LEFT JOIN ArTerms
ON ARCustomers.TermsCode = ArTerms.TermsCode)
RIGHT JOIN Orders
ON ARSummary.Reference = Orders.Reference
WHERE (ARSummary.InvoiceDate BETWEEN #5/17/2014# AND #8/15/2014#) AND ((ARSummary.Customer='PERSON'))
) AS AR LEFT JOIN
(SELECT DISTINCT(HistoryDetail.Invoice), Orders.JobNumber, HistoryDetail.Reference, HistoryDetail.InvoiceDate, Sum(HistoryDetail.Quantity) AS SumOfQuantity, Customers.Customer
FROM Orders
RIGHT JOIN ((HistoryDetail LEFT JOIN Applicants ON HistoryDetail.AppId = Applicants.ApplicantID)
LEFT JOIN Customers
ON HistoryDetail.Customer = Customers.Customer)
ON Orders.Reference = HistoryDetail.Reference
GROUP BY HistoryDetail.Invoice, Orders.JobNumber, HistoryDetail.Reference, HistoryDetail.InvoiceDate, Customers.Customer HAVING ((Customers.Customer='PERSON'))
) AS Temps
ON AR.Invoice = Temps.Invoice
ORDER BY AR.JobNumber, AR.JobDescription, AR.InvoiceDate, Temps.Customer, AR.Invoice
...我有点茫然，几天来一直在仔细检查日期字段，这似乎是我在研究中发现的最常见的原因，但是交换哈希标签和ansi引号对错误没有影响。
这份报告已经投入生产了大约六年，几个月前我们的软件供应商将他们的软件包更新到MSSQL，并选择将A / R数据分开并放在少数脱节的Access DB中。
作为将所有内容移植到Web（此处：https://www.personnelinc.com/include/system/tools/activity/reports/usage/#）的“管道”的VMS软件在MySQL上本机运行，但没有使用MySQL调用来收集MSSQL / Access数据（它们分开运行MySQL和MSSQL之间没有共享信息。）
@Brad：我实现了更改和建议，并更新了生成的代码/ sql，我仍然得到相同的数据类型不匹配错误，当我将代码直接粘贴到Access时，代码仍然运行（虽然现在快得多）。
