RecordInsertList Dynamics 365 Finance & Operations

A shortcode example of how to can create records in a table very performant way using RecordInsertList. Who does not know RecordInsertList, can learn more about it here.

static void HowToUseRecordInsertList(Args _args)
{
    DMOPerfTest DMOPerfTest;
    RecordInsertList RecordInsertList;
    Counter c;
    FromTime fromTime = timeNow();
    
    RecordInsertList = new RecordInsertList(tableNum(DMOPerfTest));
    
    for (c=1;c<=10000;c++)
    {
        DMOPerfTest.clear();    
        DMOPerfTest.AccountNum = int2str(c);
        
        if(DMOPerfTest.validateWrite())
        {
            RecordInsertList.add(DMOPerfTest);
        }
    }
    
    RecordInsertList.insertDatabase();
    
    info(strFmt("Total time consumed: %1", timeConsumed(fromTime, timeNow())));

Bulk Database Operations Recordset D365FO/AX 2012

Recordset operations or set based operators

We all noticed that AX 2012 and D365FO get slow from time to time when we performed insertion or update operations on huge numbers of records one by one, and to overcome this issue, Microsoft has a feature to update or insert in bulk in a single statement.

We have 3 types of Bulk Operations

insert_recordset
update_recordset
delete_from

insert_recordset :

insert_recordset copies data from one or more tables directly into one resulting destination table on a single server trip. Using insert_recordset is faster than using an array insert. However, array inserts are more flexible if you want to handle the data before you insert it.

insert_recordset is a record set-based operator, which performs operations on multiple records at a time.

Syntax :

The list of fields in the destination table must match the list of fields in the source tables.
Data is transferred in the order that it appears in the list of fields.
Fields in the destination table that are not present in the list of fields are assigned zero-values as in other areas in X++. System fields, including RecId, are assigned transparently by the kernel in the destination table.

insert_recordset DestinationTable ( ListOfFields )

select ListOfFields1 from SourceTable [ where WhereClause ]

[ join ListOfFields2 from JoinedSourceTable

[ where JoinedWhereClause ]]

Example :

The records, "myNum" and "mySum", are retrieved from the table another table and inserted into the table myTable. The records are grouped according to "myNum", and only the "myNum" records with a value less than or equal to 100 are included in the insertion.

insert_recordset myTable (myNum, mySum)
select myNum, sum(myValue)
from anotherTable
group by myNum
where myNum <= 100;

update_recordset :

The X++ SQL statement update_recordset enables you to update multiple rows in a single trip to the server. This means that certain tasks may have improved performance by using the power of the SQL server.

update_recordset resembles delete_from in X++ and to UPDATE SET in SQL. It works on the database server-side on an SQL-style record set, instead of retrieving each record separately by fetching, changing, and updating.

If the update method is overridden, the implementation falls back to a classic looping construction, updating records one by one just as delete_from does for deletions. This also means that the construction works on temporary tables, and whole-table-cached tables by using the looping construction.

Example :

MyTable tableBuffer;
;
update_recordset tableBuffer
setting field1 = field1 * 1.10;

delete_from :

You can delete multiple records from a database table by using a delete_from statement. This can be more efficient and faster than deleting one record at a time by using the xRecord.delete method in a loop.

If you have overridden the delete method, the system interprets the delete_from statement into code that calls the delete method one time for each row that is deleted.

Example :

static void DeleteMultiRow1aJob(Args _args)
{
MyWidgetTable tabWidget;
;
delete_from tabWidget
where tabWidget .quantity <= 100;

}

But these set-based operations will roll back to row-by-row operation when either of the following condition is true:

it is not an SQL table (Eg. temporary table)
Database log is enabled for the table
Alert is set up for this table
Record level security is enabled for the table
AOSValidation method is overwritten

when using insert_recordset
the .insert() method is overwritten

when using update_recordset
the .update() method is overwritten

when using delete_from
the .delete() method is overwritten
DeleteAction is defined

To prevent it from fallback to row-by-row operation, the following method can be used if:

Delete action is defined, use skipDeleteActions
Database log is setup, use skipDatabaseLog
Alert is setup, use skipEvents
Method is overloaded (.insert(), .update, .delete()), use skipDataMethods

Definition of List, Set, Container, and Map

Difference between List, Set, Container, and Map

Containers:

Containers are dynamic and have no limits. They can contain elements of
almost all data types: boolean, integer, real, date, string, container,
arrays, tables, and extended data types. However, objects may not be stored
in containers.

Containers in AX are used very often. It’s easy to work with them. But…
data in containers are stored sequentially and thus retrieved sequentially.
This means that containers provide slower data access if you are working with
_large numbers_ of records. In case of large numbers of records use temporary
tables.

List:

Lists are structures that may contain any number of elements that are
accessed sequentially. Lists may contain values of any X++ type. All the
values in the list must be of __the same__(this is the main difference
between lists and containers) type, given in the creation of the list. The
implementation of lists is such that the traversal of the list elements is __very
fast.

Take a look for example at the class Dialog addControl() method.
Their controls are stored in ctrls List.

Map:

A map is a data type that associates one (key) value with another value [An
analog – a small table in memory with two fields: Keys, Values]. Both the key
and value values may be of any valid X++ type, including objects. The types
of the key and the value are given in the declaration of the map. The
implementation of maps is such that access to the values is _very fast_.

Don’t confuse map X++ types with Map objects in AOT, which are used for
mapping tables with similar structures of fields
–

Set:

The functionality of Sets is similar to the list. A Set is just an unordered list of items, while a list of items held by a Map
are indexed via a key.
Take look at
\Classes\sysLabel\LabelModuleId().

intermediate language CIL IL D365FO

What is an intermediate language?

Intermediate language (IL) is an object-oriented programming language designed to be used by compilers for the .NET Framework before static or dynamic compilation to machine code. The IL is used by the .NET Framework to generate machine-independent code as the output of the compilation of the source code written in any .NET programming language.

IL is a stack-based assembly language that gets converted to bytecode during the execution of a virtual machine. It is defined by the common language infrastructure (CLI) specification. As IL is used for the automatic generation of compiled code, there is no need to learn its syntax.

This term is also known as Microsoft intermediate language (MSIL) or common intermediate language (CIL).

Interfaces & Abstract Class

Interfaces VS Abstract Class?

The class implementing is the interface that implements all interface methods and there will not be any abstract Class requirement. There are many access modifiers available like abstract, protected, virtual, internal, public, and many more that are useful in the abstract Classes. Abstract classes will be very fast when compared to interfaces.

Abstract class contains both the incomplete or complete methods and the interface is the signature for a particular method. The abstract class is the implemented method but the interface cannot be an implemented method.

The abstract class contains constructors, fields, or destructors for implementing the properties. The interface does not contain constructors, fields, or destructors but they have only the property’s signature with no implementation.
The abstract class does not support multiple inheritances and the interface supports multiple inheritances. The class can also inherit more interfaces but only a single abstract class.

Pass By Reference and Pass By Value

Difference Between Pass By Reference And Pass By Value?

Pass By Reference:

In Pass by reference address of the variable is passed to a function. Whatever changes made to the formal parameter will affect the actual parameters

The same memory location is used for both variables. (Formal and Actual)
It is useful when you are required to return more than 1 value.

Pass By Value:

In this method value of the variable is passed. Changes made to formal will not affect the actual parameters.
Different memory locations will be created for both variables.
Here there will be a temporary variable created in the function stack that does not affect the original variable.

In the case of pass-by value, the change in the sub-function will not cause any change in the main function whereas in pass-by-reference the change in the sub-function will change the value in the main function.

Pass by value sends a COPY of the data stored in the variable you specify, pass by reference sends a direct link to the variable itself. So if you pass a variable by reference and then change the variable inside the block you passed it into, the original variable will be changed. If you simply pass by the value, the original variable will not be able to be changed by the block you passed it into but you will get a copy of whatever it contained at the time of the call.

What are AOS in AX & D365FO

AOS in AX & D365FO

The Microsoft Dynamics AX / D365FO (Finance & Operations) Object Server (AOS) is the second-tier application server in the Microsoft Dynamics AX three-tier architecture.

The AX 2012 3-tier environment is divided as follows:

First Tier – Intelligent Client
Second Tier – AOS
Third Tier – Database Server

In D365FO N-tier environment is divided as follows:

X-Tier – AOS, and Batch servers
X-Tier – Database Server

In an N-tier solution, the database runs on a server as the X tier; the AOS handles the business logic, Batch jobs/ background process in multiple tiers, and handles the user interface and necessary program logic.

Why are that people prefer TempDB over InMemory tables while using them in queries for reports?

Answer: Despite both being temporary type tables.

TempDB

You can use TempDB Table the SSRS report with a large amount of data without losing performance.

TempDB tables can be used in Joins with the other temp table or regular table.

Memory Table

Slow performance with a huge number of records.

couldn't use the inMemory table in the query with a join.

What Is An Index?

A SQL index is used to retrieve data from a database very fast. Indexing a table or view is, without a doubt, one of the best ways to improve the performance of queries and applications.

A SQL index is a quick lookup table for finding records users need to search frequently. An index is small, fast, and optimized for quick lookups. It is very useful for connecting relational tables and searching large tables.

SQL indexes are primarily a performance tool, so they really apply if a database gets large. SQL Server supports several types of indexes but one of the most common types is the clustered index. This type of index is automatically created with a primary key.
