OQL查询中的REGEX

时间:2015-07-23 11:12:46

标签: regex oql

我想在查询OQL对象时使用regexp,所以我的select语句将是:

SELECT o  FROM testObject o WHERE ((o.name REGEXP '^d') )

但在这里我得到了像

这样的异常

有没有办法在OQL对象上使用正则表达式?

1 个答案:

答案 0 :(得分:1)

根据Java Tools Tutorials - Herong's Tutorial Notes

  

OQL基于JavaScript表达式语言。

正则表达式检查可以在WHERE子句中执行,如下所示:

SELECT o  FROM testObject o WHERE "/^d/(o.name.toString())"

OQL正则表达式语法似乎是very poor。因此,并非所有正则表达式都适用于此。
