我有两个名为“ updateList”和“ selectedUpdateList”的列表视图，以及一个“ undangundang.db”数据库。 “ updateList”列表视图包含来自json的数据，并且是多个选择，而“ selectedUpdateList”列表视图包含用户从“ updateList”列表视图中选择的数据。
JSON：
{
idfile: "1139",
judul: "PP No 30 Th 2016 - Pemindahan Ibu Kota Kabupaten Nias Dari Wilayah Kota Gunungsitoli Ke Wilayah Kecamatan Gido Kabupaten Nias Provinsi Sumatera Utara",

我希望用户单击下载按钮，并且如果JSON中的“ judul”包含单词“ 2019”，它将以folder_id = 2将数据插入到“ undangundang.db”，如果包含单词“ 2018”，它将插入folder_id = 3的数据，依此类推，直到包含单词“ 1945”的数据，它将添加folder_id = 76的数据。

folderID++;
string update = @"INSERT INTO undangundang (uu_id, folder_id, identifier, filename, folder_parent_id) SELECT null, " + folderID + ",'" + itemDetail.Judul.Split('-')[0].TrimEnd() + "'," +
"'" + itemDetail.Judul.Replace(" ","_") + ".pdf',2 WHERE not exists (select uu_id and folder_id and identifier and filename and folder_parent_id FROM undangundang where uu_id=null and folder_id=" + folderID +

我有一个问题，如果在“ updateList”列表视图中选择的项目不止一个，那么成功输入数据库的数据只是选择的第一个数据。如何处理？
