sql - 查询SQL数据库时出现EOF和BOF错误

Question

我正在尝试从 vbs 查询 SQL 数据库，但是当没有找到记录时，我收到一个错误

ADODB.Field : Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

我想我需要使用 IF NOT 语句来捕获是否找不到记录，但我无法弄清楚它需要去哪里。

Do Until objFile.AtEndofStream
    strAppName = objFile.ReadLine

    ConnString="DRIVER={SQL Server};SERVER=aardvark002;UID=***;PWD=***;DATABASE=DEW_Users"
    SQL = "USE Win7AppData SELECT " & Chr(34) & strCountry & Chr(34) & " FROM AppsByCountry WHERE Application = '" & strAppName & "'"

    Set Connection = CreateObject("ADODB.Connection")
    Set Recordset = CreateObject("ADODB.Recordset")
    Connection.Open ConnString
    Recordset.Open SQL,Connection
    strApproval = Recordset(strCountry)
    If StrApproval = "YES" Then
        strApproval = "Approved"
    Else
        strApproval = "Denied"
    End If
    objExcel.Cells(intRow, 1).Value = strAppname 
    objExcel.Cells(intRow, 2).Value = strCountry
    objExcel.Cells(intRow, 3).Value = strApproval
    intRow = intRow + 1
Loop

我的 VBScript 有点生疏，但你应该能够在 Recordset 上使用 .EOF 来检查它是否在最后:

Recordset.Open SQL,Connection
If Recordset.EOF = false Then
    ' have some rows, do what you want with them
End If
