访问VBA过滤代码语法错误问题

Question

我有下面的代码（礼貌allenbrowne，他的信息在代码中）。当我使用其中一列（One_or_Two_Pearl）进行筛选时，它给了我一个（查询表达式中的语法错误缺失操作符）。因为一切都很好，我无法追查这个问题。该列被定义为文本类型并包含数据（1，2，NA）。这个问题只发生在这个列上，当我调试黄色标记时表明（Me.Filter = strWhere）部分。 非常感谢您的帮助。

两个你的问题在这里：

strWhere = Left$(strWhere, lngLen) 
'For debugging, remove the leading quote on the next line. Prints to Immediate Window (Ctrl+G). 
'Debug.Print strWhere 

• 取消对Debug.Print网上看到发生了什么：
• 它试图从你的[One_or_Two_Pearl]行删除尾随 “AND” ，但没有。
