Question

我正在尝试从Json向sqllite TABLE添加一些数据。在我的代码下面，用于从json数据下载数据。并具有一个用于执行我的查询的外部sqllite类。 dbclass是sqllite类的对象，并调用dbclass.setter方法来执行我的查询

     JSONArray item_uom_list = object.getJSONArray("ItemUOM");
                        if (item_uom_list.length() > 0) {
                            dbClass.setterValues("delete from tbl_item_uom");
                            for (int i = 0; i < item_uom_list.length(); i++) {
                                JSONObject item_uom_object = item_uom_list.getJSONObject(i);
                                String a = item_uom_object.getString("Org_Id");
                                String b = item_uom_object.getString("Item_No");
                                String c = item_uom_object.getString("Code");
                                String d = item_uom_object.getString("Barcode");
                                String e = item_uom_object.getString("UOMDescription");
                                String f = item_uom_object.getString("UOMQty");
                                String g = item_uom_object.getString("AutoPrice");

                                /*String sql="insert into tbl_item_uom values('?','?','?','?','?','?','?')";
                                dbClass.setterValues(sql,new String[] {a,b,c,d,e,f,g});*/


                                dbClass.setterValues("insert into tbl_item_uom values('" + a + "','" + b + "','" + c + "','" + d + "','" + e + "','" + f + "','" + g + "')");
                            }
                        }

我有外部sqllite类，我的logcat在

Answer 1

请查看您的日志，第一行告诉您您的问题。当您尝试使用值运行查询时：

repository

您用撇号将字符串断开。在需要的地方使用两个撇号。

..., 'DIAPER-BE SURE-M 5's', ...

不是双（“）撇号，只有两个单打（'）

Answer 2

android.database.sqlite.SQLiteException：“ s”附近：语法错误（代码 1）：

A SQLite exception that indicates there was an error with SQL parsing or execution.

您可以尝试使用ContentValues。

演示

SQLiteDatabase database = this.getWritableDatabase();
for (int i = 0; i < item_uom_list.length(); i++) 
{
    JSONObject item_uom_object = item_uom_list.getJSONObject(i);
    String a = item_uom_object.getString("Org_Id");
    String b = item_uom_object.getString("Item_No");
    String c = item_uom_object.getString("Code");
    String d = item_uom_object.getString("Barcode");
    String e = item_uom_object.getString("UOMDescription");
    String f = item_uom_object.getString("UOMQty");
    String g = item_uom_object.getString("AutoPrice");


        ContentValues values = new ContentValues();
        values.put("Org_Id", a); 
        values.put("Item_No", b); 
        .......................
        ......................
        values.put("AutoPrice", g); 
        database.insert("tbl_item_uom", null, values);
}

database.close();

从json插入数据进行查询时发生sqllite异常？
