den Fehler bekommen: verursacht durch: android.database.sqlite.SQLiteException: nahe "von" - android, Laufzeitfehler

Ich erhalte diesen Fehler: "Verursacht von: Android.database.sqlite.SQLiteException: nahe "of": Syntaxfehler: CREATE TABLE Liste der Notizen (_idINTEGER PRIMARY KEY AUTOINCREMENT, NotizennameTEXT NOT NULL notes_contentTEXT NOT NULL notes_timeTEXT NOT NULL); "

Ich benutze diesen Code:

 db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
KEY_ROWID + "INTEGER PRIMARY KEY AUTOINCREMENT, " +
KEY_NAME + "TEXT NOT NULL " +
KEY_CONTENT + "TEXT NOT NULL " +
KEY_TIME + "TEXT NOT NULL);"

);

Das ist meine logcat:

Bitte helfen Sie. Danke im Voraus!

Antworten:

Zusätzlich zu den guten Ratschlägen in der anderen Antwort.

CREATE TABLE List of Notes (

Ein Tabellenname muss ein Wort sein. Erwägen ListOfNames, List_of_Names, etc.

Ändern Sie die Tabelle erstellen Abfrage wie folgt:

  String CREATE_DATABASE_TABLE = "CREATE TABLE " + DATABASE_TABLE + "("
+ KEY_ROWID + " INTEGER PRIMARY KEY," +
KEY_NAME  + " TEXT NOT NULL,"
+ KEY_CONTENT + " TEXT NOT NULL,"
+ KEY_TIME + " TEXT NOT NULL"
+ ")";

db.execSQL(CREATE_DATABASE_TABLE);

du setzt nicht "," nach jeder Spalte in der create table-Anweisung

Verwenden Sie die Kommatrennung in Ihrem Code

   db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
KEY_ROWID + "INTEGER PRIMARY KEY AUTOINCREMENT, " +
KEY_NAME + "TEXT NOT NULL, " +
KEY_CONTENT + "TEXT NOT NULL, " +
KEY_TIME + "TEXT NOT NULL);"

);
