The C++ programming language has a history going back to 1979, when Bjarne Stroustrup was doing work for his Ph.D. thesis. He began work on "C with Classes", which as the name implies was meant to be a superset of the C language. His goal was to add object-oriented programming into the C language, which was and still is a language well-respected for its portability without sacrificing speed or low-level functionality.His language included classes, basic inheritance, inlining, default function arguments, and strong type checking in addition to all the features of the C language. The first C with Classes compiler ... Read More

What will happen if the MySQL AUTO_INCREMENT column reaches the upper limit of the data type?

When the AUTO_INCREMENT column reaches the upper limit of data type then the subsequent effort to generate the sequence number fails. That is why it is advised to use a large enough integer data type for the AUTO_INCREMENT column to hold the maximum sequence value required by us. For example, if we will use TINYINT then AUTO_INCREMENT would be able to generate only 127 sequence numbers and in case of UNSIGNED TINYINT, this value can be extended up to 255.

Actually, MySQL has different comparison rules for quoted values such as strings and unquoted values such as numbers. On mixing the quoted and unquoted values in IN() function list may lead to the inconsistent result set. For example, we must not write the query with IN() function like below − Select Salary from employee where ID IN(1,’a’,2,3,’c’) Instead of this the better way to write the above query is as follows − Select Salary from employee where ID IN(‘1’,’a’,’2’,’3’,’c’)

An abstract cannot be instantiated. Therefore to use an abstract class you need to create another class and extend the abstract class and use it. If a class is final you can’t extend it further. So, you cannot declare a class both final and abstract. Example Still if you try to do so you will get a compile time error saying “illegal combination of modifiers:” final abstract class Demo{ public final void display(){ System.out.println("Hello welcome to tutorialspoint"); } } Output C:\Sample>javac Demo.java Demo.java:1: error: illegal ...

As per my knowledge, SAP doesn’t offer any development library for NCo to deal with Idocs. .Net connector is primary used for development of RFC clients.One of a common method to submit idocs to the SAP system using NCo is by using function module “IDOC_INBOUND_ASYNCHRONOUS”. This function module includes multiple table parameters containing idoc data.Function Module: IDOC_INBOUND_ASYNCHRONOUS (IDoc inbound processing via tRFC)Function Group: EDINProgram Name: SAPLEDINFollowing are the parameters:Table IDOC_CONTROL_REC_40 contains the control record, IDOC_DATA_REC_40 contains the idoc data segments.IDOC_DATA_REC_40 contains a field called SDATA.
