Question

我正在尝试创建一个SQLite数据库，但它给我一个错误，我将在下面发布代码。

public class DBHandler extends SQLiteOpenHelper {
    private static final int DATABASE_VERSION = 1;
    private static final String DATABASE_NAME = "waiters.db";
    public static final String TABLE_WAITERINFO = "waiterinfo";
    public static final String COLUMN_KEY = "key";
    public static final String COLUMN_NAME = "name";

    public DBHandler(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
        super(context, DATABASE_NAME, factory, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        String query = "CREATE TABLE " + TABLE_WAITERINFO + "(" +
                COLUMN_KEY + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                COLUMN_NAME + " TEXT, " +
                ");";
        db.execSQL(query);
    }

这是给出错误的代码。

这是错误

Answer 1

您的错误相当清楚

Caused by: android.database.sqlite.SQLiteException: near ")": syntax error

要解决此问题，请删除

上的逗号

COLUMN_NAME + " TEXT, "

到此

COLUMN_NAME + " TEXT"

无法创建SQLite数据库
