在结果集中使用oracle中的子句 - java

Question

我有一个arraylist。 arraylist包含特定表中的列值。例如，'name'是表格的一列。它具有arraylist中的xxx，yyy，zzz值。我的问题是，如何在arraylist的'in子句'中添加名称。

Arraylist<String> list = new ArrayList<String>();
list.add('xxx');
list.add('yyy');
list.add('zzz');
Select * from table where name in('xxx','yyy','zzz');

I'm not sure if this is possible with the PreparedStatement, but you can use Statement here:

Statement stmt = conn.createStatement(); 
String req = "Select * from table where name in(";
String params = "";
for (int i = 0; i < list.size(); i++) {
        if (!params.isEmpty())
          params += ",";
        params += "'"+list.get(i)+"'";
    }

req += params + ")";
ResultSet rs = stmt.executeQuery(req);
