SetArray是最好的解决方案，但它不适用于许多老司机。下面的解决方法可以在java8中使用

String baseQuery ="SELECT my_column FROM my_table where search_column IN (%s)"

String markersString = inputArray.stream().map(e -> "?").collect(joining(","));
String sqlQuery = String.format(baseSQL, markersString);

//Now create Prepared Statement and use loop to Set entries
int index=1;

for (String input : inputArray) {
     preparedStatement.setString(index++, input);
}

这个解决方案比其他难看的while循环解决方案好，其中查询字符串是通过手动迭代构建的

遵循亚当的想法。让你的准备语句select my_column from my_table where search_column in (#) 创建一个字符串x，并根据你的值列表用一些“?，?，?”填充它 然后只需更改查询中的#为您的新字符串x填充

尝试使用instr函数?

select my_column from my_table where  instr(?, ','||search_column||',') > 0

then

ps.setString(1, ",A,B,C,"); 

不可否认，这是一个肮脏的黑客，但它确实减少了sql注入的机会。在甲骨文工作。

你可以使用PreparedStatement的setArray()方法

PreparedStatement statement = connection.prepareStatement("Select * from emp where field in (?)");
statement.setArray(1, Arrays.asList(1,2,3,4,5));
ResultSet rs = statement.executeQuery();

PreparedStatement ps = u.prepareStatements(sqlBefore, values, sqlAfter, connection, "someId");
