  • RE: Varchar or Char?

    david.howell (10/16/2009)


    nVarchar can actually use more than 2 bytes for some characters e.g. chinese characters that use 3 bytes.

    Do you have a source for that? Both Books Online and every...

  • RE: Varchar or Char?

    This was a great question. Well done, John! I hope you have more of these in store for us.

    Firstly, we assume that the average is the result of an...

    A very unusual pattern, as LIKE is intended to be used with wildcard characters, but syntactically valid.

    We use it widely, where searches which can be either on...

    That standard dictates that when strings of unequal length are compared, the shorter string is first padded with spaces until it matches the length of the...

    john.arnott (10/1/2009)


    But I would like to to know where MS documents the way two strings are compared as equal even when their length differs (due to the defined length or...

  • RE: T-SQL 2008

    Mighty (10/1/2009)


    I'm of the opinion that the answer(s) are incorrect.

    CUBE and ROLLUP where already available in SQL Server 2005, so they were not introduced with SQL Server 2008.

    SQL Server 2005...

  • RE: The "Numbers" or "Tally" Table: What it is and how it replaces a loop.

    DavidL (9/25/2009)


    And no - there is no reason to use ORDER BY every time you use the tally table. There is reason to use ORDER BY every time you expect...

  • RE: The "Numbers" or "Tally" Table: What it is and how it replaces a loop.

    DavidL (9/25/2009)


    In principle, there is no reason for large tally tables to work. If you change your query as I suggested, SQL Server can weed out the high numbers before...

    DavidL (9/25/2009)


    Hi guys: Thanks for hanging in there through all my bumbling. I'm not a sql server pro, and as a result find myself in over my head...

  • RE: The "Numbers" or "Tally" Table: What it is and how it replaces a loop.

    Hi David,

    Based on visual inspection of your code, I fail to see any way that this code could cause "gaps" in the tally table. I think what you saw was...

  • RE: The "Numbers" or "Tally" Table: What it is and how it replaces a loop.

    DavidL (9/24/2009)


    It looks to me that the tally table isn't storing the values I inserted in ascending order (or at least it is not returning them in that order).

    No surprise...

    Additionally, cutting and pasting your last example into my ssms and running it as is

    --===== Presets

    DECLARE @DateStart DATETIME

    DECLARE @DateEnd DATETIME

    SELECT @DateStart = '2008-01-01 06:00',

  • RE: auto creation of statistics

    Bummer, missed a point because I overthought the question, figuring something so simple had to be a trick question.

    I know of the AUTO_CREATE_STATISTICS settings. But this setting only affects creation...

  • RE: Fixed to varying length

    elbedata (9/4/2009)


    You mean, when changing the datatype from fixed length to varying length?

    I'd hesitate to describe an unasked for removal of trailing spaces "smart". There are builtin functions to remove...
