  • RE: Performance and tuning of two queries

    And, if the query uses more than one table, use an alias and prefix all columns with the correct alias name. Remember, we have absolutely no idea what columns...

  • RE: Display only month and year as MM/YYYY

    A CONVERT to format 101 will give us format "mm/dd/yyyy". Then, using STUFF, we can remove the "dd/", leaving you with what you want:

    SELECT STUFF(CONVERT(varchar(10), GETDATE(), 101), 4, 3,...

    A basic maintenance plan is just terrible for large databases, because it rebuilds every table and every index regardless. You just can't waste that much I/O in a critical...

  • RE: Count NULL columns

    Many of us prefer to generate such code from the table itself, something like below. Uncomment the EXEC(@sql) when ready to actually run the code:

  • RE: Need to find returns where a given columns multiple returns do not contain a specific value in a different column of the result set.

    If you want just the company name returned, this should (will?) be more efficient:

    SELECT [Company Name]

    FROM dbo.CompanyInfo --#CompanyInfo

    GROUP BY

    [Company Name]

    HAVING

    MAX(CASE WHEN [Transaction...

    SET NOCOUNT ON

    to the start of the trigger:

    SET NOCOUNT ON
