Why I love working on AskTom

Today a question came in, and Swapnasis provided a nice simple test case, which makes my job so much easier.  Here’s a snippet from it


SQL> create table TTT(
  2    testid integer not null,
  3    value integer not null,
  4    time timestamp not null,
  5    unique(testid, time)
  6  );

Table created.

See line 5 ?

I’ve been working with Oracle for (well…I’d rather not say Smile) but lets just says “a number of years” dating back to version 6 of the database.  But in all of that time, I never knew that you could just write “unique”.  I have always done “constraint MY_CONSTRAINT unique (col1, col2)”.

Its probably also the reason I dont mind doing a few AskTom’s like today, ie, on a Saturday morning over breakfast coffee. Its free education Smile
