.SQLiteException: near ",": syntax error (code 1): ，编译时：

Question

我错过了什么？带有“，”的东西，但我似乎找错了地方。这是我的代码：

private static final String DATABASE_CREATE =
        "CREATE TABLE if not exists " + SQLITE_TABLE + " (" +
                KEY_ROWID + " integer PRIMARY KEY autoincrement," +
                KEY_CURSUS + "," +
                KEY_ONDERDEEL + "," +
                KEY_GAME + "," +
                KEY_TIJD + "," +
                KEY_WEB + "," +
                KEY_CHECK + "," +
                " UNIQUE (" + KEY_ROWID +"));";

这是我得到的错误：

 Caused by: android.database.sqlite.SQLiteException: near ",": syntax error (code 1): , while compiling: CREATE TABLE if not exists Games_getset (_id integer PRIMARY KEY autoincrement,cursus,onderdeel,game,tijd,web,check, UNIQUE (_id));

Answer 1

自 check is a keyword in SQL 起重命名或引用 check 列。

例如：

private static final String DATABASE_CREATE =
    "CREATE TABLE if not exists " + SQLITE_TABLE + " (" +
            KEY_ROWID + " integer PRIMARY KEY autoincrement," +
            KEY_CURSUS + "," +
            KEY_ONDERDEEL + "," +
            KEY_GAME + "," +
            KEY_TIJD + "," +
            KEY_WEB + "," +
            + "`" + KEY_CHECK + "`," +
            " UNIQUE (" + KEY_ROWID +"));";

Answer 2

您需要为您为表定义的列添加数据类型。您已为 KEY_ROWID 添加了整数数据类型，但忘记为其余部分添加数据类型。

.........KEY_ROWID + " integer PRIMARY KEY autoincrement," +
                KEY_CURSUS + " text," +
                KEY_ONDERDEEL + " text," + ........
and so on...

Answer 3

尝试在创建表命令中删除“IF NOT EXIST”，android 4.0.4 版本的 SQLite 给我这个错误，而不是 4.4.2

运气。
