Just take the code that I posted, substitute the table name, and run it in a query window in Management Studio. It will create a stored procedure, which you then can call using for example:<br />
<br />
GetLastDays 12<br />
<br />
or<br />
<br />
GetLastDays @cnt = 12<br />

<div class="content wysiwyg-content">
Hello all! <br />
I need to make a function that gets the past 12 records of the last day avaiable of each month from a date. <br />
I need to sum them then divide it for 12 to get the avarage of the period.<br />
<br />
I have a table with 3 colums (dt_date, vl_value, id_prod) which records a day by day historical (except weekends and holidays), so the last day of a month is not necessarily the last day (eg: Last day for May/2009 was not 31 but 29)<br />
<br />
Example: Today is 7/14/2009. The values I need to get are:<br />
(vl_value in 6/30/2009 + vl_value in 5/29/2009 + vl_value in 4/30/2009 + vl_value in 3/31/2009 + vl_value in 2/27/2009 + vl_value in 1/30/2009 + vl_value in 12/31/2008 + vl_value in 11/28/2008 + vl_value in 10/30/2008 + vl_value in 9/30/2009 + vl_value in 8/29/2009)/12<br />
<br />
I may have that function for 12, 6 and 24 periods...<br />
<br />
Please help!!!<br />
Thanks in advance!<br />

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server

Active Server Pages (ASP) is Microsoft’s first server-side engine for dynamic web pages. ASP’s support of the Component Object Model (COM) enables it to access and use compiled libraries such as DLLs. It has been superseded by ASP.NET, but will be supported by Internet Information Services (IIS) through at least 2022.

Microsoft SQL Server 2005 is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning. It includes support for managing XML data and allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests.

Microsoft SQL Server 2005

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
