ExcelVBA使用InstantClient连接到远程OracleDB

最终编辑/使用了此功能（不使用驱动程序/提供程序：InstantClient，但仍使用文件）：

Function ORAQUERY(strHost As String, strDatabase As String, strSQL As String, strUser As String, strPassword As String)
Dim strConOracle, oConOracle, oRsOracle
Dim StrResult As String
StrResult = ""
strCOnOracle= "Driver={microsoft ODBC for Oracle}; " & _
"COnNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
"(HOST=" & strHost & ")(PORT=1521))" & _
"(CONNECT_DATA=(SERVICE_NAME=" & strDatabase & "))); uid=" & strUser & " ;pwd=" & strPassword & ";"
Set oCOnOracle= CreateObject("ADODB.Connection")
Set oRsOracle = CreateObject("ADODB.Recordset")
oConOracle.Open strConOracle
Set oRsOracle = oConOracle.Execute(strSQL)
MsgBox (oRsOracle.Fields(0).Value)
varResult = oRsOracle.GetRows
Do While Not oRsOracle.EOF
If StrResult <> "" Then
StrResult = StrResult & Chr(10) & oRsOracle.Fields(0).Value
Else
StrResult = oRsOracle.Fields(0).Value
End If
oRsOracle.MoveNext
Loop
oConOracle.Close
Set oRsOracle = Nothing
Set oCOnOracle= Nothing
ORAQUERY = StrResult
End Function


Correct full Connection String:

Driver={microsoft ODBC for Oracle}; COnNECTSTRING=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=strHost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=strDatabase))); uid=strUser; pwd=strPassword;


Provider or Driver:

需要设置PATH环境变量以指向InstantClient。
没有使用任何其他环境变量，例如ORACLE_HOME，
TNS_ADMIN等。
