如何将反逗号存储在csv文件中，然后将该数据复制到Android中的Greendao

Question

我在csv文件中存储了一些数据。当我在绿色道中复制此数据时，带有反逗号符号的数据会给出 SQLite 异常

Caused by: android.database.sqlite.SQLiteException: near "s": syntax error (code 1): , while compiling: INSERT INTO CATEGORIES (_id, SNO, SINDHI, HINDI ,ENGLISH, DRAWABLE, AUDIO, CATEGORY) values(188,9,'सस्','सास','Wife's or Husband's Mother','R.drawable.blank','R.raw.saas','Relatives');

我想要那个符号，所以我不能在文件中进行任何更改。请帮助将该符号存储在绿色道中。这是我的一些代码：

InputStream inputStream = getResources().openRawResource(R.raw.animals);
            InputStreamReader csvStreamReader = new InputStreamReader(inputStream);
            BufferedReader buffer = new BufferedReader(csvStreamReader);
            String tableName = "CATEGORIES";
            String columns = "_id, SNO, SINDHI, HINDI ,ENGLISH, DRAWABLE, AUDIO, CATEGORY";
            String str1 = "INSERT INTO " + tableName + " (" + columns + ") values(";
            String str2 = ");";
            SQLiteDatabase db;
            DaoMaster.DevOpenHelper helper = new DaoMaster.DevOpenHelper(this, "category-db", null);
            db = helper.getWritableDatabase();
            db.beginTransaction();
            String line;
            int count=0;
            try {
                while ((line = buffer.readLine()) != null) {
                    StringBuilder sb = new StringBuilder(str1);
                    String[] str = line.split(",");
                    sb.append(count + ",");
                    sb.append(str[0] + ",");
                    sb.append("'" + str[1] + "',");
                    sb.append("'" + str[2] + "',");
                    sb.append("'" + str[3] + "',");
                    sb.append("'" + str[4] + "',");
                    sb.append("'" + str[5] + "',");
                    sb.append("'" + str[6] + "'");
                    sb.append(str2);
                    db.execSQL(sb.toString());
                    count++;
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            db.setTransactionSuccessful();
            db.endTransaction();

Answer 1

摆脱字符串串联并使用?参数占位符以及传递给execSQL()的参数数组。

或者，使用 insert() 方法。

或者，转义单引号，使用 '' 而不是 ' 。
