I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons...

• When is `x IS NOT NULL` not the same as `NOT(x IS NULL)`

  - by Mark Hurd

  For what x is The expression x IS NOT NULL is not equal to NOT(x IS NULL), as is the case in 2VL (quote from this answer, which is quoting Fabian Pascal Practical Issues in Database Management - A Reference for the Thinking Practitioner -- near the end of that answer) My guess is when x IS NULL is NULL, but I cannot guess when that would be (i.e. I haven't checked the SQL standard).

• How can I change column length using HQL query?

  - by gmugmu

  I tried session.createSQLQuery("ALTER TABLE People MODIFY address VARCHAR(1000);").executeUpdate(); but this throws org.hibernate.exception.SQLGrammarException: could not execute native bulk manipulation query After a lot of googling, the recommendation is to use HQL instead of SQL query to do bulk updates. Not sure how to use HQL to accomplish this. There seems to be no decent HQL documentation for updating column length in a table. Thanks so much for the help.
