Using “Cache” in ASP.Net

22 de Outubro de 2013 – 18:08
 Data can be stored on the client – using the view state of the page, or on the server in a variable session state or application, or using the server cache.
ASP.NET implements System.Web.Caching.Cache class to store objects that require a large amount of server resources to be created, so that they do not have to be recreated each time it is needed.
You can access via code information about a class instance cache through the property cache, the object of the HttpContext or Page object.
Expiration policy for items in cache:
  • Specific time:  absolute expiration
  • May also expire if not accessed for a period of time:  sliding expiration

MySql Group_Concat

21 de Outubro de 2013 – 9:28

The result of GROUP_CONCAT is truncated to the maximum length that is given by the group_concat_max_len system variable, which has a default value of 1024.

This will cause  data-destroying bugs in production. For this reason you should probably not use GROUP_CONCAT . At least you must set the value of group_concat_max_len to an insanely high value on every database server your application runs on.

Like MAX or COUNT, GROUP_CONCAT is a MySQL aggregation function you can use whenever your query contains a GROUP BY. You can use it to retrieve a comma-separated list of all values in a given column within each group.

select  client
,Month
,year
,Sum(Amount) as Amount_Total
,GROUP_CONCAT(Amount) as Amount_Detail
,GROUP_CONCAT(InvoiceNum) as Invoices
from mytable
 group by Client
