老师，打开项目提示“加载数据表｜123失败”，详细错误信息：
System.data.OleDb.OleDbException:无法完成延迟准备。
无法预定义语句。
列名‘zw’不明确。
在
。。。。
在
。。。。。


很多信息。
在上一次打开项目是没有这个信息的。
输出全部代码查找，没有涉及“123”的代码，在表列表里也没有找到表“|123".前两次打开项目倒是看到过123的表，但今天打开找不到，请问是怎么回事呢，怎么解决？？

下面代码中没有以”True“为列名的，但在重置列时提示运行错误。上一次打开都没有这么多错语，怎么今天打开就这么多错误呢？请老师帮忙，谢谢(老师，下面代码不提示错误了，但不提示错误，也不计算数据。。。。)

应该是某个查询表加载有问题，查询表引用的表可能改列名了，列名‘zw’不存在

提示什么错误？如果没有错误肯定就是没有符合条件的数据，或者数据没有保存。

Compute都改为sqlCompute
