Is there a way to convert sqlite to json? All other questions are parsing json and saving to sqlite. I can't seem to find any reference on this, please help me.

I have a sqlite db inside the app and i need it to be converted to json, upgrade db version, parse earlier converted json and add another table. Any suggestions on how should I do this?

Thanks in advance.

private JSONArray getResults()
{

String myPath = DB_PATH + DB_NAME;// Set path to your database 

String myTable = TABLE_NAME;//Set name of your table

//or you can use `context.getDatabasePath("my_db_test.db")`

SQLiteDatabase myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY); 

String searchQuery = "SELECT  * FROM " + myTable;
Cursor cursor = myDataBase.rawQuery(searchQuery, null );

JSONArray resultSet     = new JSONArray(); 

cursor.moveToFirst();
while (cursor.isAfterLast() == false) {

            int totalColumn = cursor.getColumnCount();
            JSONObject rowObject = new JSONObject();

            for( int i=0 ;  i< totalColumn ; i++ )

sqlite, already have json1 extension, you could use:

           //https://www.sqlite.org/json1.html

           //https://gist.github.com/akehrer/481a38477dd0518ec0086ac66e38e0e2
         var _sql = "SELECT json_group_array( json_object('id', id, 'name', name)    ) AS json_result FROM (SELECT * FROM ipfs ORDER BY id); ";

sql.js does not support json1 extension,

my working example convert raw record to json

 function json1_extension(_records){



                                      var _json = [];


                                        var _columns = _records[0].columns
                                        var _values = _records[0].values


                                          for (var i = 0; i < _values.length; i++) {
                                              //console.log(_values[i]);
                                                var _row_json = {};

                                                var _row = _values[i];
                                                for (var k = 0; k < _row.length; k++) {
                                                    _row_json[_columns[k]] = _row[k]


                                                }

                                              //console.log('_row_json...',_row_json);
                                             _json.push(_row_json)   

                                          }

  • you can get an ArrayList from your Db and with a library like Gson or Jackson convert it to JSON.
  • must be a long process. but I don't get what is with the -1.
  • try out the answer i have posted.
  • you cannot eat the banana without pealing off its skin. Similarly, you need to parse one type of data to the other manually.
  • I'm not sure I understand why this is the first time someone has asked this question, because don't you have to do this in order to sync a MySQL database to an Android SQLite database??
  • This is from the article Convert database cursor result to Json Array. It is good to post the reference link when you copy paste.
  • Not to keen on plagiarism myself.
  • Nice one buddy. - just one amend. to get your database path please use=> context.getDatabasePath("my_db_test.db") - do not hardcode as /data/data....
