sql - Generate records on interval of time (Weekly, Monthly, Quarterly, Yearly) -

-

I need to generate a record on the given start date, end-date and time-frequency (weekly, monthly etc.)

  • Expiration date: December 31, 2011

  • February 1 - 28 February (29 leap years)

  • March 1 - 31 March

    . .

    • 4 - December 1 - December 31

      Example - 2

      • Start
      • Expiry date: 31 December 2011
      • Frequency: Weekly

        Reports generated:

          1 - 15 January - 16 January

        • 2 - 17 Jan - 23 January

        • 3 24 January - 30 January

          .

          • 50- 26 December 31 December

            Also in the form of quarterly.

            Any help

            I think. Are you asking how the loop is basically months / weeks / quarters?

            It should be given that you hope you have a good start to point you in the right direction. All you have to do is just copy the SQL date functions such as DATEADD, DATEDIFF & amp; DatePart 

              announcement @startDate DATETIME announcement @EndDate DATETIME announcement @TimePeriod NVARCHAR (50) Announcement @RptDate DATETIME set @startDate = '2011/01/15' Set @EndDate = ' 12/31/2011 'SET @ Time Period =' Monthly 'SET @RptDate = @startDate WHILE @RptDate & lt; @EndDate print @RptDate start --- these dates I think you want to print out if @TimePeriod = 'monthly' set to @RptDate = DATEADD (mm, 1, DATEADD (day, day's (@RptDate) + 1 , @ RptDate)) @TimePeriod = 'Weekly' set @RptDate = DATEADD (ww, 1, DATEADD (day, -DATEPART (working day, @ RptDate) + 1, @ RptDate)) @TimePeriod = 'quarterly 'Set @RptDate = DATEADD (Qq, 1, DATEADD (qq, DATEDIFF (qq, 0, rptdate), -1) + 1) end

    mysql - BLOB/TEXT column 'value' used in key specification without a key length -

    -
    I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...
