如何使用Java或kotlin在resultset内进行查询

前一桌有 尖牙 需求 数量

第二张桌子有 尖牙 需求 项目名称 比率 UPC

你问的有点不清楚。ResultSet已经是某个查询的结果，您可以使用它的数据调用其他查询。你能更具体一点你想要达到的目标吗？嗨，我更新了我的问题。请让我知道这是否有助于我通过添加行[“Items”]=getRequestorItemDetails（wcsExternalCustomerId，rs.getObject（i））来整理它

Trying to use 2 tables. Please help me how to append the second resultset to first one

    fun resultSetToList(rs: ResultSet): List<Map<String, Any>> {
                val md = rs.metaData
                val columns = md.columnCount
                val rows = ArrayList<Map<String, Any>>()
                while (rs.next()) {
                    val row = HashMap<String, Any>(columns)
                    for (i in 1..columns) {
                        row[md.getColumnName(i)] = rs.getObject(i)
//calling sub query
getRequestorItemDetails(wcsExternalCustomerId, rs.getObject(i))
                    }
                    rows.add(row)
                }
                return rows
            }

fun getRequestorItemDetails(wcsExternalCustomerId : String, RequestorId : Any) : Any {

        var listset : Any = ""
        val results = jdbcTemplate.query(
                "SELECT ItemName, Quantity, Rate, UPC FROM table WHERE CustomerId = ? and RequestorId = ? ",
                wcsExternalCustomerId, RequestorId)
        {
            rs: ResultSet, _: Int ->
            listset = resultSetToList(rs)
        }
        return listset
