• JQuery addclass to another div (but not parent) if no data is found

  - by Danny

  I have this to add a class to the main table that the report is in if there is no data returned. $('#report-area table td:contains("Sorry, your search did not return any data")').parents('#reportArea').addClass('no-report-data') However, I have another div area "#report-footer" but it's not inside #report-area. I'd like to also add the .no-report-data class to "#report-footer" as well but in this case I don't think the .parents selector will work. Is there another selector I can use to do this?

• Hiernate's version values in Grails app

  - by xain

  Hi, looking at a database dump file, and I see many records in various tables with their version number set in values other than 0 (even 94 in one case). I understand it has to do with hibernate locking strategy, but my concern is that today is Sunday, and the site has almost no visitors so is: is this normal ? Or is there a known hibernate bug or even some programming malpractice producing this ? Thanks in advance.

• mySQL: Can I make count() honor limit clause?

  - by Stomped

  I'm trying to get a count of records matching certain criteria within a subset of the total records. I tried (and assumed this would work) SELECT count(*) FROM records WHERE status = 'ADP' LIMIT 0,10 and I assumed this would tell me how many records of status ADP were in that set of 10 records. It doesn't - it returns, in this case 30, which is the total number of ADP records in the table. How do I just count up the records matching my criteria including the limit?

• 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).
