我创建了一个 ODBC 连接来直接从 Excel 文件查询 MySQL 数据库。这是一个相当复杂的查询，大约有 60 条选择语句，在原始 MySQL 数据库和从 Microsoft Query 连接时都能完美运行。但是，当我在 Excel 工作表上发布结果时，它会显示除两列之外的所有列（都有 ## <-- THIS!!! 注释）

为了简化起见，这些是故障陈述

我不知道他们为什么失败。我已经在同一个查询中有更长的语句，并且函数 concat() 也已经工作了。我假设具有超过 3 个缩进函数的语句存在问题，但我不确定。
如果你们中有人知道为什么会失败，那将对我有很大帮助
Microsoft Query 中的正确结果
Excel 工作表中的描述列消失了
