  • RE: Pascals Triangle, Home Work and Root Cause Analysis

    Good article.

    Of course, the point you omitted is how the actual probability of any given failure alters the calculations.

    With the lottery example, because each of the numbers is (supposedly)...

  • RE: Table variable vs temp table

    The answer is correct but the explanation ("The reason is that the table variable causes a recompilation") is 100% wrong.

    The reason the table variable code is so slow is precisely...

  • RE: Union results

    Tony++ (9/22/2011)


    Lost the point but learned something new.

    I knew that union deduped the sets, but I never thought it through to the logical conclusion that it dedups all rows in...

    How many points do you lose for posting a question with the wrong answer? How about the sum of all the wrong answer.

    Good idea.

    But how many points should...

  • RE: Stairway to SQL Server Indexes: Step 8, Unique Indexes

    pnewhart (6/23/2011)


    Second, how are you demonstrating to allow duplicate NULL values using a filter? Unless some screen prints are missing, I don't see how that's being illustrated. And,...

  • RE: Database Collation

    Sudhir Dwivedi (9/12/2011)


    @richard-2 Warr:

    45% incorrect answers would imply that it wasn't an easy question! Well done to those who knew the correct answer or, like me, guessed there would be...

  • RE: Are remote databases fragmented? Let's Defrag.

    Interesting article. Since you are logging errors, do you have any statistics on how often laptop users disconnect even though they've been sent the e-mail?

    But I'm getting a 2008R2 server this month. 😀

    SQLkiwi (8/4/2011)


    IsNumeric - sigh.

    Thank goodness for the improvements in the next version of SQL Server like TRY_CONVERT.

    TRY_CONVERT - sigh.

    While it's in many ways better than IsNumeric, TRY_CONVERT does have some...

    DBCC INDEXDEFRAG (AdventureWorks_regular,"cdc.ddl_history",ddl_history_clustered_idx)-- a system table in the AdventureWorks_regular DB

    Neither of those are system tables, they are ordinary tables that happen to be used by the...

    In one run against a table with 700M rows, I receive 4513066 rows covering all dates where number = 1. In the other I receive only 13935 records for...

    Precedence has always and will always mater on all versions, flavors, and RDBMS servers that support SQL.

    True, but that's not the cause of the discussion here.
