有个VB问题，请高人指点。

 

下面这个题运行的时候为什么会提示少了IF？

 

Public Function ExecuteSQL(ByVal SQL As String, MsgString As String) As ADODB.Recordset
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim sTokens() As String
On Error GoTo ExecuteSQL_Error
sTokens = Split(SQL)
Set cnn = New ADODB.Connection
cnn.Open ConnectString
If InStr("INSERT,DELETE,UPDATE,EXECUTE", UCase$(sTokens(0))) Then cnn.Execute (SQL)
MsgString = sTokens(0) & "query successful"
Else
Set rst = New ADODB.Recordset
rst.Open Trim$(SQL), cnn.adOpenKeyset, adLockOptimistic
Set ExecuteSQL = rst
MsgString = "查询到" & rst.RecordCount & "条记录"
End If
ExecuteSQL_Exit:
Set rst = Nothing
Set cnn = Nothing
Exit Function
ExecuteSQL_Error:
MsgString = "查询错误:" & Err.Description
Resume ExecuteSQL_Exit
End Function
