SQlite - Android - Foreign key syntax

Question

I've been trying to get foreign keys working within my Android SQLite database. I have tried the following syntax but it gives me a force close:

private static final String TASK_TABLE_CREATE = "create table "
            + TASK_TABLE + " (" + TASK_ID
            + " integer primary key autoincrement, " + TASK_TITLE
            + " text not null, " + TASK_NOTES + " text not null, "
    + TASK_DATE_TIME + " text not null, FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+" ("+CAT_ID+"));";

Any ideas what I might be doing wrong? if you need to see the other table structure then I can, its just a very simple structure for the second with an ID and a name.

Edit:

Here is the error:

03-13 13:42:35.389: ERROR/AndroidRuntime(312): Caused by: android.database.sqlite.SQLiteException: unknown column "taskCat" in foreign key definition: create table reminders (_id integer primary key autoincrement, task_title text not null, notes text not null, reminder_date_time text not null, FOREIGN KEY (taskCat) REFERENCES category (_id));

Answer 1

You have to define your TASK_CAT column first and then set foreign key on it.

private static final String TASK_TABLE_CREATE = "create table "
        + TASK_TABLE + " (" 
        + TASK_ID + " integer primary key autoincrement, " 
        + TASK_TITLE + " text not null, " 
        + TASK_NOTES + " text not null, "
        + TASK_DATE_TIME + " text not null,"
        + TASK_CAT + " integer,"
        + " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+"("+CAT_ID+"));";

More information you can find on sqlite foreign keys doc.
