Top 5 programming language to learn in 2018

Hello everyone and welcome to my blog.where we are going to have the technical talks are going to talk about a lot of stuff and of course I would expect you to post some questions so that I can answer to this question going to be answering a very important question what are the top 5 programming language on which I should be focusing now these top 5 programming language of course I'm going to change over the year of time i'm talking in 2018 so this is going to be different scenario and if
you ask me this in later in the day 2020 going to be different and it was really different in 2010 so let's talk about the present scenario so what are the top five programming language that you should be focusing right now.

Top 5 programming language to learn in 2018
1.JavaScript :so it is very simple nowadays you should definitely be getting started but the
JavaScript now this was not something that you might have seen as a coming because JavaScript was not at all considered the good programming language to start up out there but nowadays it's really really important that you get started with the javascript and the reason they're pretty simple that you can merge upon variety of new technologies like node.js react.js and a tons of things are out there so you should definitely be getting started with JavaScript ok that's done with the number 1.

2.python what should be the 2nd language that you should opt, now I would say being a big fan of python I would say that you can choose python up to you you might want to choose the Titans are the Ruby but I would say just off one of them can serve you as pretty good so I would say that go for the python and you can develop some webapps or maybe some desktop application or pretty much anything in the python so that is definitely going to be the number 2 language in my list

3.Java and Swift:what comes up next is going to be really little bit tricky now I would say between the two language the java or the swift now if you are really enthusiastic about iPhone app MacBook application or Mac application or something like that then you should definitely be opting out in the swift language otherwise you can choose with java as well if you're pretty much interested in Android application or desktop application just follow the videos or maybe for the mac as well but then definitely java  should be the way to go up with that but I would say again choose between the swift and java decide your pattern right now that where you want end up you want to end up with the Mac
application developer or android application the Android application definitely it's not at all a good idea to just jump on and learned that side by side first master one of them and then you can move ahead now that comes up as a number three what should be on the number of 4.

4.Php: is pretty good it should be the PHP Now some of you might say when we have node.js or something like that why should we focus on the PHP now I would say the world is the internet what is actually quite large on a large scale are large proportion is being by the WordPress and WordPress runs entirely on the PHP and if you want to be into the development of maybe one to be some other technologies like WordPress or something PHP is a must go language.

5.SQL:so these are all about what about the number five number five Go with the SQL, snow some of you might say, this is not even a programming language yes I may agree with that but that's a different story and talk for another day right now I would say that go for the SQL it's really powerful its simple it gives you a great idea about handing the database  definitely you will be handling the database weather going with node.js or maybe mongo db   or maybe other kinds of data base but handling the databases is really important that you want to have so definitely let's just quickly
summarize what we gone in this movie

the top 5 by programming language that you should be focusing the first one I would say that always go with the JavaScript in the present scenario it can lead you with a variety of ways node js flux js and a lot of things like that number two is going to be the python the number three is going to be a smart choice by you between the swift and the java number 4 is going to be the PHP and number five is going to be that SQL now definitely I would say that add up base on the basis of what do you like
to do or did you want to go some people would say I don't need to learn Java or any of those I would be moving on to that jQuery or maybe I on the ionic frameworks or something like that like phonegaps and all of that but that's up to totally you know this was my point of view I would definitely like to know what's your point of view on this blog ok so with this now ends up
again I would say that follow like comment below down the videos please don't forget to follow blog.
was your questions below so that I can know that what video I want to make next or what we do you want me to make or on such questions your questions really make this a really really enthusiastic
blog and quite fun as well ok see you out there in the next blog.

Hack Ludo King Game Play 2018

Ludo King™ is board game played between friends, family & kids. Recall your childhood!

Ludo King is a cross platform game that supports Desktop, Android and iOS platform at same time in online multiplayer mode.

*NEW Snakes and Ladders game added.

Hack Ludo King Game Play 2018

Ludo game traces its lineage back to 6th century India. Ludo is derived from the game Pachisi. Ludo is also very similar to Spanish board game Parchís.

Ludo game has stayed popular throughout the ages, varying only a little in its game structure. This persevering game is now available for you to play in an all new modernized format, i.e. as a video game application.

The game is played between 2 to 6 players and you have the option of playing the game against the computer, against your friends, or even against people from around the world. The objective of the game is pretty straightforward; each player gets 4 tokens, these tokens must make a full turn of the board and then make it to the finish line.

Whoever gets all four tokens to the end first is the winner. However, each move can only be made based on the number decided by casting a six-sided die, and each token can only move out of their home by casting a six. Additionally, the competition factor of the games is upped by the fact that while moving if another player’s token lands on the same square as your token, then your token will automatically be sent back home and you’ll need to roll a six again.

Ludo King is a game that was once played by kings and now it can be enjoyed by you and your family and friends. While the gameplay might seem simple at first, the game is immensely enjoyable and challenging. You’ll be playing this one for hours and its fun for the whole family. Try to beat your opponents and compete for the highest scores on the leaderboards.

Another game similar in structure is Snakes and Ladders. Like Ludo, you may have played this board game when you were young. Ludo King now incorporates this classic game as a whole new level. The objective of the game is simple: you start on 1 and you have to be the first one to make it to 100. However, you can only move the same number of tiles as the number you roll on a die. The board is also littered with snakes and ladders. If you land on the same tile as the beginning of a ladder, then you can take the ladder as a shortcut and move on up. But, if you land on the mouth of a snake, then down you go to its tail. A game of ups and down, Snakes and Ladders has been a favorite for generations; and now you can play it too, with Ludo King.

Rollback/ Savepoint
All these statements fall in the category of Transaction Control Statements.
Rollback:
This is used for undoing the work done in the current transaction. This command also releases the locks if any hold by the current transaction. The command used in SQL for this is simply:
ROLLBACK;
Savepoint:
This is used for identifying a point in the transaction to which a programmer can later roll back. That is it is possible for the programmer to divide a big transaction into subsections each having a savepoint defined in it. The command used in SQL for this is simply:
SAVEPOINT savepointname;
For example:
UPDATE…..  
DELETE….  
SAVEPOINT e1;  
INSERT….  
UPDATE….  
SAVEPOINT e2;  
…… It is also possible to define savepoint and rollback together so that programmer can achieve rollback of part o a transaction. Say for instance in the above
ROLLBACK TO SAVEPOINT e2;
This results in the rollback of all statements after savepoint e2
Commit
This is used to end the transaction and make the changes permanent. When commit is performed all save points are erased and transaction locks are released. In other words commit ends a transaction and marks the beginning of a new transaction. The command used in SQL for this is simply:
COMMIT;
Experiment 10

PL/SQL
PL/SQL stands for Procedural Language/SQL.PL/SQL extends SQL by adding constructs found in procedural languages, resulting in a structural language that is more powerful than SQL. The basic unit in PL/SQL is a block, All PL/SQL programs are made up of blocks, which can be nested within each other. Typically, each block performs a logical action in the program.
Block has the following structure:
DECLARE
/* Declarative section: variables, types, and local subprograms.
*/
BEGIN
/* Executable section: procedural and SQL statements go
here. */
/* This is the only section of the block that is required. */
EXCEPTION
/* Exception handling section: error handling statements go
here. */
END;
Let us see an example of the above
DECLARE
TEMP_COST NUMBER(10, 2);
BEGIN
SELECT COST FROM JD11.BOOK INTO TEMP_COST
WHERE ISBN = 21;
IF TEMP_COST > 0 THEN
UPDATE JD11.BOOK SET COST =
(TEMP_COST*1.175) WHERE ISBN = 21;
ELSE
UPDATE JD11.BOOK SET COST = 21.32 WHERE
ISBN = 21;
END IF;
COMMIT;
EXCEPTION
WHEN NO_DATA_FOUND THEN
INSERT INTO JD11.ERRORS (CODE, MESSAGE)
VALUES(99, ‘ISBN 21 NOT FOUND’);
END;
Only the executable section is required. The other sections are optional. The only SQL statements allowed in a PL/SQL program are SELECT, INSERT, UPDATE, DELETE and several other data manipulation statements plus some transaction control. Data definition statements like CREATE, DROP, or ALTER are not allowed.The executable section also contains constructs such as assignments, branches, loops, procedure calls, and triggers, which are all described below (except triggers). PL/SQL is not case sensitive. C style comments (/* ... */) may be used.To execute a PL/SQL program, we must follow the program
text itself by· A line with a single dot (“.”), and then · A line with run;As with Oracle SQL programs, we can invoke a PL/SQL program either by typing it in sqlplus or by putting the code in a file and invoking the file in the various ways we learned in.
Getting Started With Oracle.
What are the Variables?
Information is transmitted between a PL/SQL program and the database through variables. Every variable has a specific type associated with it. That type can be · One of the types used by SQL for database columns
· A generic type used in PL/SQL such as NUMBER
· Declared to be the same as the type of some database Column
The most commonly used generic type is NUMBER. Variables of type NUMBER can hold either an integer or a real number. The most commonly used character string type is VARCHAR(n), where n is the maximum length of the string in bytes. This length is required, and there is no default. For example, we might declare:
DECLARE
price NUMBER;
myBeer VARCHAR(20);
You know that PL/SQL allows BOOLEAN variables, even
though Oracle does not support BOOLEAN as a type for
database columns.
Types in PL/SQL
Types in PL/SQL can be tricky. In many cases, a PL/SQL variable will be used to manipulate data stored in a existing relation. In this case, it is essential that the variable have the same type as the relation column. If there is any type mismatch, variable assignments and comparisons may not work the way you expect. To be safe, instead of hard coding the type of a variable, you should use the %TYPE operator. For example:
DECLARE gives PL/SQL variable myBeer whatever type was declared for the name column in relation Beers.
Experiment 11
Program 11:
Write a pl/sql for select, insert, update and delete statements.
CREATE TABLE TEMP
( ENAME VARCHAR2(10),
DESIG VARCHAR2(10),

DESIG VARCHAR2(10);
SALARY NUMBER(7,2);
ENO NUMBER(4):=&EMPNO;
BEGIN
SELECT ENAME,JOB,SAL INTO NAME,DESIG,SALARY FROM EMP WHERE EMPNO=ENO;
DBMS_OUTPUT.PUT_LINE(ENO||' '||NAME||' '||SALARY||' '||DESIG);
IF DESIG='CLERK' THEN
DELETE FROM EMP WHERE EMPNO=ENO;
INSERT INTO TEMP VALUES(NAME,DESIG,SALARY);
DBMS_OUTPUT.PUT_LINE('DELETED FROM EMP AND INSERTED TO TEMP');
COMMIT;
ELSIF DESIG='MANAGER' THEN
UPDATE EMP SET SAL=SALARY+200 WHERE EMPNO=ENO;
DBMS_OUTPUT.PUT_LINE('INCREMENTED SALARY IS '||TO_CHAR(SALARY+200));

Cursors
What are Cursors?
A cursor is a variable that runs through the tuples of some relation. This relation can be a stored table, or it can be the answer to some query. By fetching into the cursor each tuple of the relation, we can write a program to read and process the value of each such tuple. If the relation is stored, we can also update or delete the tuple at the current cursor position. The example below illustrates a cursor loop. It uses our example relation T1(e,f) whose  tuples are pairs of integers. The program will delete every tuple whose first component is less than the second, and insert the reverse tuple into T1.
DECLARE
/* Output variables to hold the result of the query: */
a T1.e%TYPE;
b T1.f%TYPE;
/* Cursor declaration: */
CURSOR T1Cursor IS
SELECT e, f
FROM T1
WHERE e < f
FOR UPDATE;
BEGIN
OPEN T1Cursor;
LOOP
/* Retrieve each row of the result of the above query
into PL/SQL variables: */
FETCH T1Cursor INTO a, b;
/* If there are no more rows to fetch, exit the loop: */
EXIT WHEN T1Cursor%NOTFOUND;
/* Delete the current tuple: */
DELETE FROM T1 WHERE CURRENT OF T1Cursor;
/* Insert the reverse tuple: */
INSERT INTO T1 VALUES(b, a);
END LOOP;
/* Free cursor used by the query. */
CLOSE T1Cursor;
END;
Experiment 13

open c1;       
loop      
fetch c1 into name,hdate;      
exit when c1%NOTFOUND;      
dbms_output.put_line(name||' '||hdate);      
end loop;      
close c1;
end;

Ques2:-Write a query to show dept where no sales representative works using cursor?
Triggers
A trigger (essentially, a stored SQL statement associated with a table) is a database object that defines events that happen when some other event, called a triggering event, occurs. Create a trigger by using the CREATE TRIGGER statement. Triggers execute when an INSERT, UPDATE, or DELETE modifies a specified column or columns in the subject table. Typically, the stored SQL statements perform an UPDATE, INSERT, or DELETE on a table different from the subject table. Sometimes a statement fires a trigger, which in turn, fires another trigger. Thus the outcome of one triggering event can itself become another trigger. The Teradata RDBMS processes and optimizes the triggered and triggering statements in parallel to maximize system performance.
Trigger Functions
Use triggers to perform various functions:
• Define a trigger on the parent table to ensure that UPDATEs and DELETEs performed to the parent table are propagated to the child table.
• Use triggers for auditing. For example, you can define a trigger which causes INSERTs in a log record when an employee receives a raise higher than 10%.
• Use a trigger to disallow massive UPDATEs, INSERTs, or DELETEs during
business hours. For example, you can use triggers to set thresholds for inventory of each item by store, to create a purchase order when the inventory drops below a threshold, or to change a price if the daily volume does not meet expectations.
Restrictions on Using Triggers
Teradata triggers do not support FastLoad and MultiLoad utilities and, and
you must disable triggers before you run load utilities. In addition, a positioned
(updatable cursor) UPDATE or DELETE is not allowed to fire a trigger and
generates an error.
Note: You cannot define a join index on a table with a trigger.
CREATE TRIGGER <triggername> AFTER UPDATE/INSERT/DELETE  OF   <COLUMN NAME> ON <TABLENAME> FOR EACH ROW           
BEGIN             
-----            
-----            
executable statements;            
-----
