“使用VBA将数据从Excel导出到SQL Server时，将数据类型varchar转换为数字时出错”

Question

我在Excel中创建了一个宏来从SQL Server导入和导出数据。 但是，当我尝试导出数据时，它会抛出错误

[Microsoft] [ODBC SQL Server驱动程序] [SQL Server]
将数据类型varchar转换为数字时出错

我导出整数时代码工作正常。 当我尝试导出实数时出现错误。

Dim gil, gibnr, gul, fil, fibnr, ful, qil, qibnr, qul, xil, xibnr, xul, oil, oibnr, oul, cil, cibnr, cul, nil, nibnr, nul, bul, hul, lul, indul As Long


conn.Execute "insert into dbo.Intl_LL (UWU,OBU,Profile_ID, Insured_name,   Claim_number,Claim_desc,  Event_Name,   UY, AY, AQ, Date_of_loss,   Region, CCY,    Policy_number,  Branch, LE, MPL,Claim_alert_email,     Comments,   [Large Profile Flag], [Earmark Flag],   [Tracked for Qtrly dev],  [Gross Incurred], [Gross IBNR], [Gross Ultimate], [FAC Incurred],   [FAC IBNR],   [FAC Ultimate],   [QS Incurred],[QS IBNR],[QS Ultimate],[XOL Incurred],[XOL IBNR],[XOL Ultimate],[Ceded OTH Incurred],[Ceded OTH IBNR],[Ceded OTH Ultimate],[Ceded Total Incurred],[Ceded Total IBNR],[Ceded Total Ultimate],[Net Incurred],[Net IBNR],[Net Ultimate],[Booked Ultimate],version)" & _
     "values ('" & sUWU & "', '" & sOBU & "','" & sProfile & "', '" & sInsured & "','" & sClaim & "','" & sClmdesc & "','" & sEvent & "','" & sUY & "','" & sAY & "','" & sAQ & "','" & sDOL & "','" & sRegion & "','" & sCCY & "','" & sPolnum & "','" & sBranch & "','" & sLE & "','" & sMPL & "','" & sClaimalert & "','" & sComm & "','" & sLargeF & "','" & sEarF & "','" & sTrackF & "','" & gil & "', '" & gibnr & "','" & gul & "','" & fil & "','" & fibnr & "','" & ful & "','" & qil & "','" & qibnr & "','" & qul & "','" & xil & "','" & xibnr & "','" & xul & "','" & oil & "','" & oibnr & "','" & oul & "','" & cil & "','" & cibnr & "','" & cul & "','" & nil & "','" & nibnr & "','" & nul & "','" & bul & "', '" & ver & "')"

我确保在VBA中具有Long数据类型的变量在SQL Server中是numeric(7, 11)类型。

请随时询问有关该问题的更多信息。 谢谢。

Answer 1

MySQL必须假设这些值应该与“mycol”列的类型相同，并以静默方式转换它们。 - 当您尝试将INT与字符串进行比较时，它也会这样做。

但是，您应该尽量不引用应该是数字的值。 即使MySQL确实自动转换其中的一些，它也会花费几个周期，并且行为可能不一致。

底线：始终不加引号，只引用字符串和日期。
