"Missing columns in relationship" when creating table

I have tried to create three tables(CUSTOMERS, VEHICLES and RENTALS), the third table (RENTALS) has foreign keys referring to the two primary keys of the first two tables (CUSTOMERS and RENTALS). When creating this third table I get an error Missing columns in relationship(Rel=CUSTOMERS[[]] -> RENTALS[[]])
Here's my codes
private void createTables() throws SQLException {
Statement statement = conn.createStatement();
statement.executeUpdate("CREATE TABLE CUSTOMERS(custNumber AUTOINCREMENT PRIMARY KEY, " +
"firstName VARCHAR(155) NOT NULL, surname VARCHAR(155) NOT NULL, idNum INTEGER NOT NULL, phoneNum INTEGER NOT NULL, canRent BIT NOT NULL)");
statement.executeUpdate("CREATE TABLE VEHICLES(vehNumber AUTOINCREMENT PRIMARY KEY, make VARCHAR(155) NOT NULL, " +
"category VARCHAR(155) NOT NULL, rentalPrice FLOAT NOT NULL, availableForRent BIT NOT NULL)");
statement.executeUpdate("CREATE TABLE RENTALS(rentalNumber AUTOINCREMENT PRIMARY KEY, dateRental VARCHAR(155) NOT NULL, dateReturned VARCHAR(155) NOT NULL, " +
"pricePerDay FLOAT NOT NULL, totalRental FLOAT NOT NULL, custNumber INTEGER FOREIGN KEY REFERENCES CUSTOMERS(custNumber), " +
"vehNumber INTEGER FOREIGN KEY REFERENCES VEHICLES(vehNumber))");
System.out.println("Database populated");
}
and here's the error
Your help will be very much appreciated, I have looked around but found nothing that helps.

In Access, an AutoNumber field (DDL: AUTOINCREMENT or COUNTER) is a "Long Integer".
In UCanAccess DDL, INTEGER creates an "Integer" (16-bit) field and LONG creates a "Long Integer" (32-bit) field.
You need to declare your foreign key columns as LONG, not INTEGER.

Problem with create temporary table mysql in java program

I'm new on java programming.
I've a problem with creation a temporary table in Java..
Database db = new Database();
String query="create temporary table sconti (codcon int(11) not null, " +
" sigcos char(4) not null, codgru char(4) not null, codsgr char(4) not null, " +
" desgru char(100) not null, dessgr char(100) not null, sconto1 double(16,4) not null, " +
" sconto2 double(16,4) not null,sconto3 double(16,4) not null,primary key(codcon,sigcos,codgru,codsgr));";
db.executequery(query);
With first instruction I connect to the database then do the query with executequery
the debug error is:
Field 'codgru' doesn't have a default value

If you set a column as not null, you have to set a Default value. This is missing for some columns in query.
So remove not null or add a default value.

Why is sqlite auto_increment not incrementing?

I've got a database set up to store notes. I want to auto increment the first column. I've tried this, but when I read from the database every result in that column is 'null'.This is the code for creating the DB.
private static final String NOTES_TABLE_CREATE =
"CREATE TABLE " + NOTES_TABLE_NAME + " (" +
COLUMN_NAMES[0] + " INTEGER AUTO_INCREMENT, " +
COLUMN_NAMES[1] + " TEXT, " +
COLUMN_NAMES[2] + " TEXT, " +
COLUMN_NAMES[3] + " TEXT, " +
COLUMN_NAMES[4] + " TEXT, " +
COLUMN_NAMES[5] + " TEXT, " +
COLUMN_NAMES[6] + " TEXT);";
This is the code for getting the DB result.
SQLiteDatabase db = this.getReadableDatabase();
Cursor result = db.query(NOTES_TABLE_NAME, COLUMN_NAMES, null, null, null, null, null, null);
result.moveToFirst();
result.moveToNext();
System.out.println(result.getInt(0));
System.out.println(result.getString(1));
This is the output from logcat
04-09 17:56:17.981 22147-22147/com.example.a8460p.locationotes I/System.out: 0

AUTO_INCREMENT (as opposed to INTEGER PRIMARY KEY AUTOINCREMENT) is not supported in sqlite.
This is a little non-obvious, because sqlite silently ignores column constraints it does not recognize:
sqlite> CREATE TABLE test (
a INTEGER FABBELBABBEL NOT NULL
);
sqlite> .schema test
CREATE TABLE test (a INTEGER FABBELBABBEL NOT NULL);
sqlite> INSERT INTO test (a) VALUES (1);
sqlite> INSERT INTO test (a) VALUES (NULL);
Error: NOT NULL constraint failed: test.a
AUTOINCREMENT on the other hand, is supported for integer primary keys and only there, so the obvious workaround attempt is not supported, either:
sqlite> CREATE TABLE test (a INTEGER AUTOINCREMENT NOT NULL, b INTEGER);
Error: near "AUTOINCREMENT": syntax error
In short: Auto increment is only available for integer primary keys.

Syntax error creating a foreign key

I am trying to create the following tables design but I am getting this error below how can I set the foreign key for the stops table in the arrivaltimes table?
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FOREIGN KEY REFERENCES stops(stop_id) )' at line 4
stt.execute("CREATE TABLE IF NOT EXISTS stops"
+ "(stop_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, "
+ " name varchar(30) NOT NULL, " + " route INT(11) NOT NULL, "
+ " lat double(10,6) NOT NULL, "
+ " longi double(10,6)NOT NULL) ");
stt.execute("CREATE TABLE IF NOT EXISTS arrivaltimes(id INT(11) NOT NULL PRIMARY KEY,"
+ " weekday VARCHAR(20) NOT NULL,"
+ "arrivaltime time NOT NULL,"
+ " stop_id INT FOREIGN KEY REFERENCES stops(stop_id) )" );

Change
stop_id INT FOREIGN KEY REFERENCES stops(stop_id)
to
stop_id INT, FOREIGN KEY fk_stop_id(stop_id) REFERENCES stops(stop_id)

I have updated the query, please take note of the syntax of the FOREIGN KEY, where you had an error. Cheers!
stt.execute("CREATE TABLE IF NOT EXISTS stops"
+ "(stop_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, "
+ " name varchar(30) NOT NULL, " + " route INT(11) NOT NULL, "
+ " lat double(10,6) NOT NULL, "
+ " longi double(10,6)NOT NULL) ");
stt.execute("CREATE TABLE IF NOT EXISTS arrivaltimes(id INT(11) NOT NULL PRIMARY KEY,"
+ " weekday VARCHAR(20) NOT NULL,"
+ "arrivaltime time NOT NULL,"
+ " FOREIGN KEY (stop_id) REFERENCES stops(stop_id) )" );

If you look at the MySQL CREATE TABLE syntax, then you have the choice between:
An inline definition (note the absence of FOREIGN KEY)
stop_id INT REFERENCES stops(stop_id)
and an explicit definition:
stop_id INT,
FOREIGN KEY (stop_id) REFERENCES stops(stop_id)
or better (with named constraint):
stop_id INT,
CONSTRAINT fk_arrivaltimes_stops FOREIGN KEY (stop_id) REFERENCES stops(stop_id)

MySQLSyntaxErrorException when creating table

I am fairly new to MySQL with Java, but I have executed a few successful INSERT queries however cannot seem to get the CREATE TABLE query to execute without getting the MySQLSyntaxErrorException exception. My code is as follows:
Statement stmt;
String url = "jdbc:mysql://localhost:3306/mysql";
Connection con = DriverManager.getConnection(url, "root", "password");
stmt = con.createStatement();
String tblSQL = "CREATE TABLE IF NOT EXISTS \'dev\'.\'testTable\' (\n"
+ " \'id\' int(11) NOT NULL AUTO_INCREMENT,\n"
+ " \'date\' smallint(6) NOT NULL\n"
+ ") ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;";
stmt.executeUpdate(tblSQL);
stmt.close();
con.close();
And the error is as follows:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near ''dev'.'testTable' (
'id' int(11) NOT NULL AUTO_INCREMENT,
'date' smallint(6) N' at line 1
I would appreciate it if anyone could spot the mistake in this query, as I've tried executing this within phpMyAdmin and it works as it should.

\n will make press enter effect :) make it like
String tblSQL = "CREATE TABLE IF NOT EXISTS `dev`.`testTable`"
+ "("
+ "id INTEGER(11) NOT NULL AUTO_INCREMENT primary key,"
+ "date smallint(6) NOT NULL"
+ ")"
+ "ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;";
