I wanna create a simple db but i got syntax error can anyone help me to fix this.Here is my db helper:

private static final int DATABASE_VERSION=1;
private static final String DATABASE_NAME="userDatabase";
private static final String TABLE_NAME="person";
private static final String USER_NAME="user";

public MyDatabaseHelper(Context context) {
    // TODO Auto-generated constructor stub
     super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase arg0) {
    // TODO Auto-generated method stub

    String CREATE_USER_TABLE="create table"+TABLE_NAME+"("
            +USER_NAME+"text primary key);";
    arg0.execSQL(CREATE_USER_TABLE);
