Question

我试图通过hibernate在grails中实现映射，以获得一个在columne名称中有特殊字符的表。即“ - ”

域类中的映射

//properties
    Boolean  h00_02

//mapping
    static mapping = {
     h00_02 column : 'h00-02'
     }

异常堆栈跟踪：

查询：您有什么想法，我该如何解决上述问题。我试图逃避它，但它也没有工作。我必须使用上面提到的列名，因为我试图在现有数据库上开发UI。

提前致谢！

Answer 1

这有用吗？

static mapping = {
  h00_02 column : '`h00-02`'
}

（或者，当你说“我试图逃避它”时，你的意思是什么？）

Hibernate Mapping在别名为“h002-01”的列的Grails中生成错误
