使用Java的PreparedStatement将数组传递给SQL查询

我使用Java的预处理语句将数组传递给SQL查询时遇到了一些麻烦。 我首先尝试了sourceforge驱动程序，但是当我调用setArray方法时，我会得到AbstractMethodError。 不知道我交换到Microsoft sqlserver驱动程序的解决方案，但现在我完全得到一个不同的错误，即“java.sql.SQLFeatureNotSupportedException：不支持此操作”。 尝试了很多东西来尝试解决这个问题，但似乎没有任何工作可行。

我的Java代码看起来类似于我在这里和互联网上看到的例子，如下所示，

PreparedStatement ps = connection.prepareStatement(query); String[] suppliers = {"21","2774","120563","3714","59"}; ps.setArray(1, connection.createArrayOf("text", suppliers)); ResultSet rs = ps.executeQuery(); 

我的SQL查询示例。 真正感兴趣的唯一一条就是前一行，我添加了’？’ 字符，据我所知，它是如何将参数传递给SQL查询。

 productsPrices.query = select contract.supplierid as 'hotelid' \ , round((rate.s1/money.buy)*euro.sell,0) as "single" \ , round((rate.s2/money.buy)*euro.sell,0) as "double" \ ,service.Name as 'roomtype' \ ,stock.alloc - stock.taken as 'stock.available' \ , contract.notes as 'boardType' \ , object.name as 'occupancy' \ ,object.cap as 'capacity' \ ,object.mincap as 'min capacity' \ ,stock.date as 'date' \ from stock stock \ inner join rate rate on stock.rateid = rate.id \ inner join contract contract on rate.contractid = contract.id \ inner join service service on contract.serviceid = service.ID \ inner join object object on service.objectid = object.ID \ inner join band band on contract.termsid = band.ID \ inner join Money money on band.moneyid = money.id \ inner join Money euro on euro.Name = 'Euros' \ where stock.date > getdate() \ and stock.closed = 0 \ and (stock.alloc - stock.taken) > 0 \ and stock.date > getdate() \ and contract.supplierid in (?) \ and contract.Finish > GETDATE()

我通过动态生成具有所需问号数量的字符串来解决同样的问题。 这是一个片段： –

 String param = "("; for(int i=0;i
