  • RE: CTE Syntax

    Koen Verbeeck (3/30/2015)


    Such a bad habit to start a CTE with

    ;WITH

    I hate it :-D/quote]

    I totally agree! This leads to sloppy code development and debugging nightmares. Besides, it's ANSI standard...

  • RE: First Episodes

    Gary Varga (3/23/2015)


    He had extremely fond memories of it and felt that watching the series again, but a quarter of a century on and though adult eyes this time, would...

  • RE: Limitations of MongoDb

    David.Poole (3/10/2015)


    Years ago I raised the point that NOSQL actually meant NO-RDBMS and got shot down in flames. With the adoption of CQL, N1QL, AQL and lots of things...

    I currently support Mongo, SQL Server, MySQL, and increasingly PostGres, which offers an interesting hybrid document db datastore on top of a relational db.

    Great, so...

  • RE: Limitations of MongoDb

    It all comes down to this: use the right tool for the right job. NoSQL databases have their uses and function well in that space just as RDBMS databases...

  • RE: SOME rows

    Brian Hibbert (1/30/2015)


    SOME and ANY are operators rather than standalone functions even though they look like functions.

    I believe that this is consistent in style with operators such as IN.

  • RE: SOME rows

    Good introduction Steve! I've never used the SOME function before.

    I think it's also pertinent to point out that the reason all 8 rows returned was because of the use...

  • RE: Getting IT Out of the Data Center

    I have to agree that in most business organizations, the IT department is treated pretty much the same as the maintenance department. It's always seen as a cost center,...

  • RE: Restricted LEFT JOIN

    Yet, not surprising when you consider that the parent table has 1.85M rows, the child table has 7.5M rows, and the validation table has 54K. The indexes were optimized...

  • RE: Restricted LEFT JOIN

    Chris' solution works well in environments with low to medium data volume, but in the very high data volume environment I have it's too slow. I'm considering other alternatives.

  • RE: Restricted LEFT JOIN

    Serg,

    You are correct that it essentially transforms the INNER JOIN into a sub-query.

    SELECT A.Item, B.Descr, C.Color

    FROM (SELECT 1 as Item UNION ALL SELECT 2 as Item UNION ALL SELECT 3...

    serg-52 (1/13/2015)


    OK, may be just filter them in WHERE ?

    Unfortunately, that would filter out rows, not columns.

  • RE: Restricted LEFT JOIN

    ChrisM@Work (1/13/2015)


    There are two issues here which might be causing some confusion.

    Firstly, the FROM list of your query, which looks like

    SELECT ...

    FROM parent

    LEFT JOIN child to parent

    INNER JOIN grandchild...

  • RE: Error messages

    Ed Wagner (1/12/2015)


    They must want someone who knows things by the book instead of someone someone who knows the technology by using it. :sick:

    That's why I have a huge...

  • RE: Error messages

    It is indeed a good question. However, I think the requirement of a primary key was a bit misleading as it can also occur when the field is simply...
