Question

我有一个人类跟着

public class Person{
   String name;
   //----------
}

我想查询名称如“name1”的人名单，名称如“name2”，名称如“name3”.... 所以，我想有这样的功能

public void queryPersonsWhithNameLike(List<String>  names){
   //here is my query
   String queryStr = "select p from Person p where p.name LIKE :names.get(0) AND p.name LIKE :names.get(1) AND p.name LIKE :names.ger(2) AND......";

}

请问如何使用sql和jpql编写此类查询？

Answer 1

public void queryPersonsWhithNameLike（List names）{ 迭代List并构造一个查询：

String queryStr = "select p from Person p";
int count=0;
for(String str:names) {
   if(count==0) queryStr+="WHERE p.name LIKE :name"+count;
   else queryStr+=" AND p.name LIKE :name"+count;
   count++;
}
... Initialize query
for(String str:names) {
... Set all the :name+count as parameters
}

JPQL SQL基于参数列表进行查询
