can't seem to create new table in sqlite android
i have come into quite a funny hole here. i can't seem to be able to create a 2nd database table to my existing one. i basically want them to be of the same structure and the same of columns, in other words a copy of my existing table. my goal is to copy the values from my first table to the second table. The first table i created works cos i have used it already.
i have tried everything i know, unistalled and reinstalled the app to clear the database, changed the name of the tables, version..etc but i keep getting a "table not found exception". please any ideas what could be causing this and how to go about it?.. thanks
here is the creation for both of them:
/* tables variable*/
public static final String DATABASE_TABLE = "Memo";
public static final String ROUTE = "Route";
public static final String KEY_ID = "_id";
public static final String NAME = "Title";
public static final String DATE = "date";
public static final String TIME = "time";
public static final String VENUE = "venue";
public static final String CATEGORY = "category";
public static final String PRIORITY = "priority";
public static final String NOTES = "notes";
private static final String DATABASE_CREATE = "create table Memo (_id integer primary key autoincrement,"
+ "Title text, date text, time text,"
+ "venue text, category text,"
+ "priority text, notes text);";
private static final String DATABASE_CREATE_ROUTE = "create table Route (_id integer primary key autoincrement,"
+ "Title text, date text, time text,"
+ "venue text, category text,"
+ "priority text, notes text);";
public void onCreate(SQLiteDatabase db) {
db.execSQL(DATABASE_CREATE);
Log.d(TAG, "created Memo table");
db.execSQL(DATABASE_CREATE_ROUTE );
Log.d(TAG, "created Route table");
}
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
Log.w(TAG,"upgrading Database from version"+ oldVersion+ "to"
+newVersion+ "which old data will be lost");
db.execSQL("DROP开发者_JAVA技巧 TABLE IF EXITS Memo");
db.execSQL("DROP TABLE IF EXITS Route");
onCreate(db);
}
}
public void copyData(long rowId){
db.execSQL("insert into ROUTE select * from DATABASE_TABLE WHERE KEY_ID = rowId");
}
Logcat Exception is:
10-22 15:47:17.326: ERROR/Database(807): Failure 1 (no such table: ROUTE) on 0x1d7f20 when preparing 'insert into ROUTE select * from DATABASE_TABLE WHERE KEY_ID = rowId'.

Could it be referring to your DATABASE_TABLE in the insert string? I assume it needs to be "insert into ROUTE select * from " + DATABASE_TABLE + " WHERE KEY_ID = rowId"
EDIT: I think Aaron might correct too/instead.
I think you are missing a paren in your DATABASE_CREATE and DATABASE_CREATE_ROUTE
private static final String DATABASE_CREATE = "create table Memo (_id integer primary key autoincrement,"
+ "Title text, date text, time text,"
+ "venue text, category text,"
+ "priority text, notes text;";
^ (HERE?)
