数据库异常错误 SQLLITE 和 FLUTTER

Question

Can I get some help with this please...I am getting error like

1) near "VALUES": syntax error
I/flutter ( 6415): DatabaseException(near "VALUES": syntax error (code 1 SQLITE_ERROR): , while compiling: INSERT INTO words (

here is my dart model code..it says something is wrong here

[Here][1]

Wordtable is my SQLite model where I'm saving the data and Word is my backend model where I'm fetching the data to save into SQLite one

I tried to make it short and precise as possible so please do let me know if any further clarification is needed. Thank you and happy new year

class WordList {
  List<Word>? words;

  WordList({this.words});

  factory WordList.fromJson(List<dynamic> json, String lang) {
    List<Word> words = json.map((i) => Word.fromJson(i, lang)).toList();

    return new WordList(
      words: words,
    );
  }
}

class WordTableList {
  final List<WordTable>? words;

  WordTableList({this.words});

  factory WordTableList.fromJson(List<dynamic> json) {
    List<WordTable> words = json.map((e) => WordTable.fromMap(e)).toList();

    return new WordTableList(
      words: words,
    );
  }
}

Answer 1

The query in plantTableQuery is incomplete:

 INSERT INTO words (... word_main_audio, story_audio, VALUES ( '${words.WORD_ID}', '${words.TINA}', ... ```

SQLite has diagrams on their website that show the syntax of commands. They show you that in a CREATE TABLE query:

• the column-name s should be enclosed in brackets (you don't have a closing bracket ) )
• there are commas between column-name s, but there can't be one before the closing bracket ) .

The CREATE TABLE diagram shows you that the query in variable CREATE_TABLE may not have a comma before the closing bracket ) that encloses the column-def s, either:

 ... word_main_audio TEXT, story_audio TEXT, )

Answer 2

You have a syntax error in your INSERT query near values.

Insert should be in this format

INSERT INTO table (column1,column2 ,..)
VALUES( value1, value2 ,...);

You are missing closing brackets just after column story_audio.

    return ''' INSERT INTO words (
    word_id,

    coke,
    idusidusi,
    ivosavosa,
    itakataka,
    vosa_vakalatina,
    word_main_image,
    word_main_audio,
    story_audio)
