Code Optimzation in AX 2012



1. Smart Joins : 
                  Try to Use Joins instead of nested while loop wherever possible.


2. Select Statement : 

                      Mention the field names in the select statement instead of fetching entire row, this will reduce data amount to transfer from database.
                                 e.g " Select Itemid from inventTable "

3. Display Methods : 

                              Make sure that generic display methods should be moved at table leveland cached by using"Formdatasource.cacheAddmethod". 

4. Local caching :

                     Use Variables for storing the constantly used calculated values in loop , by doing so you can reduce the calls to the database and different layers.

5. Monitor the Database Calls : 

                                     For bulk records updation,deletion,insertion use RecordSet Based operator like update_recordset , delete_from and insert_recordset.

6. Aggregate Function: 

                              Use sum, avg, minof, maxof and count where applicable. Because this can utilize the database’s built-in function instead of calculating and analyse data in Axapta.

Form Auto refresh in D365 fo

Here I will explain one of the requirements I came across to refresh from automatically without User interaction.  Note: Make sure we do have all the handlers to stop UIrefreshing after certain hours of execution, else it causes the system to slow down after a certain time of continuous usage of this UI in the below example to overcome this case we use to check session login time and stopping form to refresh after certain hours of execution. Recommended to use this on pages that hold less data or smaller data sets. - NoofSeconds .value() is an integer control on UI that allows the user to choose a value.( best to fix a value like 5 seconds or a Minimum value to avoid unnecessary executions) Create a new form method and create as of below. void refreshFormWithTimeout (AsyncTaskResult _result)     {         System.Exception ex;         try         {              if(!element.closed...

SQL script to Fetching Tables list holding more data

  There may be times when we need to restore a database from a non-production or production environment for troubleshooting purposes, and we may encounter a DB size issue or need to know a list of tables with large amounts of data in order to enable purging them. This query returns a list of tables that contain large amounts of data in sequential order.  Query to Execute in SQL SELECT s.Name AS SchemaName             ,t.Name AS TableName             ,p.rows AS RowCounts             ,CAST(ROUND((SUM(a.used_pages) / 128.00), 2) AS NUMERIC(36, 2)) AS Used_MB             ,CAST(ROUND((SUM(a.total_pages) - SUM(a.used_pages)) / 128.00, 2) AS NUMERIC(36, 2)) AS Unused_MB             ,CAST(ROUND((SUM(a.total_pages) ...
