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

有没有办法在OQL对象上使用正则表达式？
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。
