尝试在 android studio 中创建 sqlite table 时出现语法错误

Question

我搜索了大约 2 小时（google，youtube 和此处）哪里做错了，但无法理解是什么。我在日志中收到此错误

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.cage.roll.midleprojectfinal/com.cage.roll.midleprojectfinal.MainActivity}: android.database.sqlite.SQLiteException: near ")": syntax error (code 1): , while compiling: CREATE TABLE IF NOT EXISTS tblmovies(movieId INTEGER PRIMARY KEY AUTOINCREMENT,movieName VARCHAR,movieSummery VARCHAR,imageURL VARCHAR,);

Caused by: android.database.sqlite.SQLiteException: near ")": syntax error (code 1): , while compiling: CREATE TABLE IF NOT EXISTS tblmovies(movieId INTEGER PRIMARY KEY AUTOINCREMENT,movieName VARCHAR,movieSummery VARCHAR,imageURL VARCHAR,);

到目前为止我发现我没有使用任何 sqlite 保留字并且创建 table 中的空格没问题....这是我的代码：

public class MoviesOpenHelper extends SQLiteOpenHelper {
SQLiteDatabase database;
//DB properties
public static final String DATABASENAME="movies.db";
public static final String TABLE_MOVIES="tblmovies";
public static final int DATABASEVERSION=1;

//DB members in static mode to gain access to all APP classes
public static final String COLUMN_ID="movieId";
public static final String COLUMN_MOVIENAME="movieName";
public static final String COLUMN_MOVIESUMMERY="movieSummery";
public static final String COLUMN_IMAGEURL="imageURL";

//Creating the DB table
private static final String  CREATE_TABLE_MOVIES =" CREATE TABLE IF NOT EXISTS " + TABLE_MOVIES + " ("
        + COLUMN_ID +  " INTEGER PRIMARY KEY AUTOINCREMENT,"
        + COLUMN_MOVIENAME + " VARCHAR,"
        + COLUMN_MOVIESUMMERY + " VARCHAR,"
        + COLUMN_IMAGEURL + " VARCHAR,"  +   ");";

public MoviesOpenHelper (Context context) {
    super(context, DATABASENAME, null, DATABASEVERSION);

}
//this wiil create the DB in the name "MOVIES"
@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(CREATE_TABLE_MOVIES);
    Log.e("data", "Table movies created");
}

//updates the new DB
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_MOVIES);
    onCreate(db);

}

}

Answer 1

CREATE TABLE IF NOT EXISTS tblmovies(movieId INTEGER PRIMARY KEY AUTOINCREMENT,movieName VARCHAR,movieSummery VARCHAR,imageURL VARCHAR,);

这是因为最后一个 VARCHAR 关键字后的尾随逗号…
