If you want to issue a CREATE, DROP or ALTER command in SQL, which function should you call on your Statement: executeQuery(), executeUpdate(), or execute()?

executeUpdate, as you are doing SQL DDL statements. You should get zero rows returned in the update count.

If you want to execute a DDL statement from java, it is enough to run a stored procedure.. In the stored procedure use execute_immediate (for 8i and above) for executing the DDL statements.
If your oracle version 8 and use
DBMS_SQL.PARSE,DBMS_SQL.DEFINE_COLUMN,
DBMS_SQL.EXECUTE, for executing DDL statements
