这是我创建数据库表的代码:
public void onCreate(SQLiteDatabase db) {
Log.i(TAG, "Inizio creazione database MessagesDB");
String CREATE_TABLE = "CREATE TABLE " + TABLE2 + " (" + Key_key + " TEXT PRIMARY KEY, " + Key_ID + " INTEGER NOT NULL, " + Key_author + " TEXT NOT NULL, "
+ Key_date_create + " TEXT NOT NULL, " + Key_sender + " TEXT, "
+ Key_date_sent + " TEXT, " + Key_recipient + " TEXT, "
+ Key_date_received + " TEXT, " + Key_message + " TEXT, "
+ Key_message_path + " TEXT, " + Key_size + " INTEGER" + ");";
try {
db.execSQL(CREATE_TABLE);
Log.i(TAG, "Creazione database MessagesDB avvenuta con successo");
}
catch (Exception e){
Log.e(TAG, "Errore nella create table messages", e);
}
}
但我在logcat中有错误:
:Errore nella create table messages
:android.database.sqlite.SQLiteException: near "create": syntax error: CREATE TABLE messagesDB (_key TEXT PRIMARY KEY, _id INTEGER NOT NULL, author TEXT NOT NULL, date create TEXT NOT NULL, sender TEXT, date_sent TEXT, recipient TEXT, date_received TEXT, message TEXT, message_path TEXT, size INTEGER);
我不明白为什么会出现这个错误。 有人能帮我理解吗? (抱歉我的英语不好)。
答案 0 :(得分:3)
从create
移除date create TEXT NOT NULL
。你似乎错误地添加了它。
看起来Key_date_create
的值为date create
,也许您的意思是date_create
?
