As I tend to forget the syntax of Oracle SQL commands, I will write them down here, every time I have to look them up. Beginning now: Turn off variable replacement in SQL+ set define off; Add Column alter table <tablename> add column <column_name> <column_datatype> <column_constraint> Example: alter table test_table [...]

Recently I digged a little in the mechanism of our ID generation. One of our IDs was annotated like this: @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = “myIdGen”) @SequenceGenerator(name = “myIdGen”, sequenceName = “MY_SEQUENCE”) protected Long id; But seemingly the underlying (Oracle-)sequence remained untouched.
