Can jdbc be written once but run everywhere?

Question

hi everybody,
i am using jdbc. Since for different databases, their sql statements are not exactly the same. So my jdbc program which is written for an Oracle database cannot run for a MySQL database. For example, in Oracle, i created a silly table like this:
CREATE TABLE hello (
id integer,
primary key (id) );
but in MySQL, in order to create the same table, i have to modify my sql statement like this:
CREATE TABLE hello (
id integer primary key );
So , if i create such a table in my jdbc program, i have to modify my codes so as to migrate my jdbc program from Oracle to MySQL. For a java programmer who wants his programs to be written once but run everywhere, this is not a beautiful thing.
I dont know if SUN has provided some technologies to avoid this dependence. Perhaps SUN has defined a unified sql for java(jsql?) and make the translation from jsql into special sql of different databases a task of jdbc drivers?

Hi,
This is a simple one compared to the lazy way that MS decided to implement Access database and the sql code. The wildacard * does not work from java programs where you have to use the %.
Fortunately, maybe, standards are improving, but be aware that you may have to know silly discrepancies until there is proper standardisation.
This includes the different spellings between English and American too.
