mysql 关键字 desc_MySQL的desc关键字作为了字段名称查询问题

时间：2023-07-18 22:49:41

引言：今天在开发的时候，由于业务需求，所有要在产品表的数据库中多查询一个字段(产品描述信息)，字段名称是desc.

原本数据库查询语句如下：

" select id, name, price, martPrice, picturePath, firstImgUrl, smallImgUrl, stock, productNo, rootOrgId from EntProduct where id = ?"

新增字段后修改为如下：

" select id, name, price, martPrice, picturePath, firstImgUrl, smallImgUrl, stock, productNo, rootOrgId, desc from EntProduct where id = ?"可能很多人觉得这个语句没有问题，但是在执行查询的时候出现下面的异常信息：

java.lang.RuntimeException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: desc near line 1, column 94 [select id,name,price,martPrice,picturePath,firstImgUrl,smallImgUrl,stock,productNo,rootOrgId,desc from com.product.vo.EntProduct where id=?]

org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: desc near line 1, column 94 [select id,name,price,martPrice,picturePath,firstImgUrl,smallImgUrl,stock,productNo,rootOrgId,desc from com.product.vo.EntProduct where id=?]
