  • Reply To: Comparison of varchar data from two different tables

    It seems like this is a character comparison.  If so, "00:15:18" would not compare correct "0:...", since you have two leading zeros vs one leading zero.  If you're going to...

    Don't change the CASTing for the bits in the WHERE clause, leave as is.  Otherwise I believe SQL will default to a different data type which would force a column...

    Somehow you left out the "SET @MyBit = 0" on one function?

  • Reply To: Create a dynamic script to create view for all tables having MAX columns

    Except stay completely away from INFORMATION_SCHEMA views, which are more overhead anyway.  Use sys.tables, sys.columns, etc., instead.

    And what would you want to name the view?

  • Reply To: Conditionally Selecting Rows within Union

    Sample data and results are almost always clearer than just a textual explanation.  I hope this matches what you need:

    SELECT
    ISNULL(t2.CarColor, t1.CarColor) AS CarColor,
    ...

    IF I understand the q correctly, then:

    SELECT
    ISNULL(t2.CarColor, t1.CarColor) AS CarColor,
    t1.CarName,
    t1.CarStatus
    FROM Db1.CarTbl1 t1

  • Reply To: Replace and like - oh great

    SQL wouldn't necessarily have to scan the entire table, if the relevant columns happened to be in a nonclus index -- not likely here, but theoretically possible.

    (1) Yes, to me, highly impractical.

    (2) No real need to make the db read only:

    (A) take diff backup (if you feel safer that way);

    (B) Switch to SIMPLE recovery;

    (C) Issue a...

  • Reply To: Performance optimization by excluding JOIN with tables only with one record

    Perhaps, but I would really expect SQL to generate effectively the same query plan for either code for something this straight forward.

  • Reply To: Performance optimization by excluding JOIN with tables only with one record

    Your code is not really consistent, but here's my best guess:

    UPDATE pt 
    SET LastModifiedDateTime = @dt
    FROM dbo.PlayersTypes AS pt
    INNER JOIN @TableTypePlayersRestrictions AS prt ON prt.PlayersRestrictionID = pt.PlayersRestrictionID
