   • What do you think is the best way to keep a partitioning table unique?

     Top Answer

     Answered Nov 06, 2022 · 0 votes

     We must see the queries to answer this kind of question.

     If you don't have a million rows, don't bother with PARTITIONing.

     Only BY RANGE provides any performance, and only in certain situations. See Partition

     Too many ranges or too few ranges will hurt performance. (I like 10 to 50, but that is not hard and fast.)

     AUTO_INCREMENT requires only that it be the first column in some index. As long as you don't deliberately try to set such a column, it won't matter that it is not declared unique.

     What Uniqueness constraints do you really need?

     You may have a "natural" PK, thereby avoiding AUTO_INCREMENT.

     Be aware that you should re-think all indexes when switching to/from Partitioning. A simple, but partial, rule is that the "partition key" should be last, not first, in any indexes.

     The cost of testing for Uniqueness is probably much worse than not having Partitioning. It is likely to require an extra SELECT, and that may have to hit every partition.

     A partitioned table is essentially a bunch of tables, plus "pruning" to pick which one (or several) tables to look in.

   • What do you think of multiline lambdas in VB 10

     Top Answer

     Answered Oct 30, 2008 · 14 votes

     Personally, I think that VB's syntax for delegates and lambdas is completely bogus. I mean, come on, AddressOf! This was fine in VB6. It is definitely not fine in a language such as VB.NET where functions should be treated as first-class citizens (although they really aren't, of course) and where conversion from method groups to delegates is more or less transparent.

     Now the introduction of inline functions is horribly verbose. I actually believe that the C# approach – x => f(x) would fare very well in VB because it shows exactly what it does. At the current state, I prefer C# for any functional programming work, which is a pity because I generally favour VB.

     Now, I really rejoice that VB finally gets multiline lambdas and statement lambdas because they're still useful sometimes (take the case of Parallel.For). But the syntax is messed up. The same goes for iterators, by the way (if they should make it into VB10).

     By preference I'm a C# developer, but have been using VB 9 almost exclusively for about a year now. The #1 thing about VB 9 that breaks my heart is the limited lambdas. Lambdas in VB 9 are limited in the following ways:

     • Only one statement.
     • They must return a value.

     So the ForEach method on collections will not work with lambdas, and only the very simplest of operations will work. So most of the time you have to move your logic to some other method and use AddressOf. Many times this cleaves the readability of the code in a dramatic and heartbreaking way.

     It's something that I feel many would not pick up on unless they've used anonymous methods fluently in another language that fully supports them (C#, JavaScript, etc.), rather than the crippled support they have in VB 9.

     I'm extremely relieved that they're fixing lambdas in VB 10.

     I can think of two reasons off the top of my head why I love it! Been waiting too long for this.

     First:

     Private Sub SomeMethod() Dim SomeVariable as String = "Some text."- AddHandler SomeButton.Click, Sub() SomeVariable += " Some more text" MessageBox.Show(SomeVariable) End Sub-

     Second:

     Private Sub SomeMethodRunningInAnotherThread() Me.Dispatcher.Invoke(Normal, Sub() 'Do some other stuff ' SomeTextBox.Text = "Test" End Sub) End Sub-

   • What do you think that the error_reporting(1); instruction makes?

     Top Answer

     Answered Sep 26, 2010 · 2 votes

     E_ERROR

     is defined as 1

     , so it's the same as

     error_reporting(E_ERROR);-

     So basically it tells PHP only to report fatal errors.

     As Skilldrick says, you should use named constants, as their defined values can and will change through newer versions of PHP. One well-known such example is E_ALL, which had the following values (from the same PHP manual table):

     • 30719 in PHP 5.3.x (currently)
     • 6143 in PHP 5.2.x
     • 2047 previously
