how to update table in sqflite with flutter

Question

when I try to update a table with id nothing won't happen. I got no error and I have no idea why this happens. at first, I try to get all data from fields, and then if all fields have value then make the User object and pass into the method for the update table. I got id from the previous screen and other data from fields. as I check I have all data inside the validate method in CompleteUserInformationScreen and I think error occur somewhere when I try to call update method with sqflite.

this is my method for the update table:

 Future<User> update(User user) async {
    var dbClient = await db;
    // return await dbClient.update(USER_TABLE, user.toMap(),
    //     where: '$NATIONAL_ID = ?', whereArgs: [user.nationalId]);
    var res = await dbClient.rawQuery(
        'UPDATE Customer SET $NAME = ${user.name}, $FAMILY = ${user.family}, $BIRTHDAY = ${user.birthday}, $MOBILE = ${user.mobile}, $NATIONAL_ID = ${user.nationalId} WHERE id = ${user.id}');

    if (res.length > 0) {
      return new User.fromMap(res.first);
    }
    return null;
  }

and this is my screen:

      ),
    );
  }
}

Edit:

after did some change in code I got this error:

Error Code: 1 (SQLITE_ERROR) E/flutter (18587): Caused By: SQL(query) error or missing database. E/flutter (18587): (near "00": syntax error (code 1): , while compiling: UPDATE User SET name = mehrdad, family = dolat, birthday = 1450-12-31 00:00:00.000, mobile = 0936, nationalId = 001 WHERE id = {id: 1}) E/flutter (18587): #################################################################) sql 'UPDATE User SET name = mehrdad, family = dolat, birthday = 1450-12-31 00:00:00.000, mobile = 0936, nationalId = 001 WHERE id = {id: 1}' args []}

updated code:

  Future<User> update(String id, String name, String family, String birthday,
      String mobile, String nationalId) async {
    var dbClient = await db;
    var res = await dbClient.rawQuery(
        'UPDATE $USER_TABLE SET $NAME = $name, $FAMILY = $family, $BIRTHDAY = $birthday, $MOBILE = $mobile, $NATIONAL_ID = $nationalId WHERE id = $id');

    if (res.length > 0) {
      return new User.fromMap(res.first);
    }
    return null;
  }

and in my screen:

  dbHelper.update(
          id.toString(),
          nameController.text,
          familyController.text,
          birthday.toString(),
          mobileController.text,
          nationalIdController.text);

      navigateToUsersList(ctx);

Edit Number 2:

I think we need just one more step to do this:

I do a new change on update method in database helper:

   Future<int> update(String id, String name, String family, String birthday,
      String mobile, String nationalId) async {
    var dbClient = await db;
    return await dbClient.rawUpdate(
        'UPDATE $USER_TABLE SET $NAME = \'$name\', $FAMILY = \'$family\' ,$BIRTHDAY = \'$birthday\', $MOBILE = \'$mobile\' , $NATIONAL_ID = \'$nationalId\' WHERE $ID = ${int.parse(id)}');
  }

and when I try to add an Id for where section I got this error:

[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: FormatException: Invalid radix-10 number (at character 1) E/flutter (21459): {id: 2}

but if I hardcoded id for example where $ID = 2 everything works fine. how I can fix this issue? why {} add beside id? and how I must remove it

Answer 1

I used this article to implement my Database. There you can find all things you need to interact with your database.

this will work for you, you just need to implement the "toMap" Method in the User class:

Future<void> update(User user) async {
    final dbClient = await database;
    var res = await db.update("Customer", user.toMap(),
        where: "id = ?", whereArgs: [user.id]);
    return res;
  }

Answer 2

after some search and trying I found the solution:

update method in db_helper:

  Future<int> update(String id, String name, String family, String birthday,
      String mobile, String nationalId) async {
    var dbClient = await db;
    return await dbClient.rawUpdate(
        'UPDATE $USER_TABLE SET $NAME = \'$name\', $FAMILY = \'$family\' ,$BIRTHDAY = \'$birthday\', $MOBILE = \'$mobile\' , $NATIONAL_ID = \'$nationalId\' WHERE $ID = ${int.parse(id)}');
  }

and validate method in Screen:

 validate(BuildContext ctx) async {
    if (nameController.text != "" &&
        familyController.text != "" &&
        nationalIdController.text != "" &&
        mobileController.text != "") {
      final dbHelper = DBHelper();

      dbHelper.update(
          id.toString(),
          nameController.text,
          familyController.text,
          birthday.toString(),
          mobileController.text,
          nationalIdController.text);

      navigateToUsersList(ctx);
    } else {
      showFlushBar(ctx, "error", "Please fill all fields");
    }
  }

A simple way to update the table in SQLite DB.

• Here is my table

id	URL

• SwiperList is my table name

• Id is primary key with auto incrementation property

• URL is simple text value

   Future<int> update(String id, String url) async { final db = await database; return await db.rawUpdate( 'UPDATE SwiperList SET url = $url WHERE id = ${int.parse(id)}');

  }

You can implement it according to your requirement.
