Question

我在java中有一个mysql查询，如

public static BusObjectIterator<con.PROJECT_EMP> GetEmpObjectsforOrgandMultipleCategory(String ORG, String CATEGORY)
    {
String query=select * from PROJECT_EMP where org = :ORG and category=:CATEGORY;
.....
return ...
}

这里param ORG将具有单个值，如xyz和CATEGORY String可能有多个值，如Cat1，Cat2等..，所以我想动态地使用REGEX来构建查询，以替换逗号分隔的字符串值，如

select * from PROJECT_EMP where org = 'xyz' and category in ('Cat1','Cat2');

感谢。

您可以使用FIND_IN_SET()功能代替RegEx

试试这个：

SELECT * FROM PROJECT_EMP WHERE org = :ORG AND FIND_IN_SET(category,:CATEGORY);

REGEX mysql用于逗号分隔值
