Do you know How many types of Joins in SQL. In this ppt presentation we are discussion about types of joins in sql server eg: INNER JOIN , SELF JOIN ,OUTER JOIN ,Right outer Join,Left outer Join,Full Outer Join,CROSS JOIN .
PL/SQL is a combination of SQL along with the procedural features of programming languages.
It provides specific syntax for this purpose and supports exactly the same datatypes as SQL.

Notes for C Programming for MCA, BCA, B. Tech CSE, ECE and MSC (CS) 4 of 5 by...ssuserd6b1fd
C programming language notes for beginners and Collage students. Written for beginners. Colored graphics. Function by Function explanation with complete examples. Well commented examples. Illustrations are made available for data dealing at memory level.
In this chapter we will explore strings. We are going to explain how they are implemented in C# and in what way we can process text content. Additionally, we will go through different methods for manipulating a text: we will learn how to compare strings, how to search for substrings, how to extract substrings upon previously settled parameters and last but not least how to split a string by separator chars. We will demonstrate how to correctly build strings with the StringBuilder class. We will provide a short but very useful information for the most commonly used regular expressions. We will discuss some classes for efficient construction of strings. Finally, we will take a look at the methods and classes for achieving more elegant and stricter formatting of the text content.
Developer Experience i TypeScript. Najbardziej ikoniczne duoThe Software House
Wiktor Toporek: TypeScript bez wątpienia jest obecnie pewnym standardem wśród obecnych rozwiązań powstałych w JavaScripcie. Ale czy poza byciem dodatkiem który uzupełnia odrobinę dokumentacje i deklaruje kontrakt jakiego typu parametry przyjmują i zwracają np. funkcje jakiejś biblioteki, można wycisnąć z niego coś więcej? Podczas prezentacji wykorzystamy TypeScript do granic możliwości, używając zaawansowanych technik które sprawiają że interfejs naszego API będzie sam kierował używających go developerów na drogę poprawnego użycia, które jest zgodne z naszymi (twórców) założeniami, poprawiając tym samym ich doświadczenia.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.

3. 1) STRING FUNCTION
SQL | String functions
String function are used to perform an operation on input string and return an output
string.
Following are the string functions defined in SQL:
1)ASCII(): This function is used to find the ASCII value of a character.
Syntax: SELECT ascii('t');
Output: 116
4. 2)CHAR_LENGTH(): This function is used to find the
length of a word.
Syntax: SELECT char_length('Hello!');
Output: 6
3)CHARACTER_LENGTH(): This function is used to
find the length of a line.
Syntax: SELECT CHARACTER_LENGTH('ANKIT
DUBEY');
Output: 11
5. 4)CONCAT(): This function is used to add two words
or strings.
Syntax: SELECT 'Ankit' || ' ' || 'Dubey' FROM dual;
Output: ‘AnkitDubey’
5)LCASE(): This function is used to convert the given
string into lower case.
Syntax: LCASE ("ANKIT DUBEY");
Output: Ankit dubey
6. 6)LEFT(): This function is used to SELECT a
sub string from the left of given size or characters.
Syntax: SELECT LEFT('Ankit S. Dubey', 5);
Output: Ankit
7)LENGTH(): This function is used to find the
length of a word.
Syntax: LENGTH('AnkitDubey');
Output: 10
&many more.............................................
9. 2)AGGREGATE FUNCTION:
Aggregate functions in SQL:
In database management an aggregate function is a function where the
values of multiple rows are grouped together as input on certain criteria
to form a single value of more significant meaning.
Various Aggregate Functions Are:
1) Count()
2) Sum()
3) Avg()
4) Min()
5) Max()
10. • Now let us understand each Aggregate function with a example:
Id Name Salary
-----------------------
1 A 80
2 B 40
3 C 60
4 D 70
5 E 60
6 F Null
1)Count():
Count(*): Returns total number of records. i.e 6.
Count(salary): Return number of Non Null values over the column salary. i.e 5.
Count(Distinct Salary): Return number of distinct Non Null values over the column salary
.i.e 4
11. Sum():
sum(salary): Sum all
Non Null values of
Column salary i.e.,
310
sum(Distinct salary):
Sum of all distinct
Non-Null values i.e.,
250.
Avg():
Avg(salary) =
Sum(salary) /
count(salary) = 310/5
Avg(Distinct salary) =
sum(Distinct salary) /
Count(Distinct Salary)
= 250/4
Min():
Min(salary):
Minimum value in
the salary column
except NULL i.e., 40.
Max(salary):
Maximum value in
the salary i.e., 80.
12. EXAMPLE OF AGGREGATE FUNCTION(INPUT):
USE ankit;
CREATE TABLE employee(id INT, fnam VARCHAR(10),snam VARCHAR(10),address VARCHAR(10),salary INT,age INT);
INSERT INTO employee(id,fnam,snam,address,salary,age
VALUES(1,'ANKIT','DUBEY','NALASOPARA',50000,25);
SELECT *FROM employee;
SELECT SUM(salary)FROM employee;
SELECT COUNT(salary)FROM employee;
SELECT AVG (salary) FROM employee;
SELECT MIN(salary) FROM employee;
SELECT MAX(salary) FROM employee;
14. 3.) "DATE FUNCION"
• It returns the name of the day and month of a
given date expression. This function is used to add a number of days,
months, years to the given date expression.
By the use of Date Function we show the
• the current date.
•Date functions in SQL with examples
•SQL | Date functions
• NOW(): Returns the current date and time. ...
• CURDATE(): Returns the current date. ...
• CURTIME(): Returns the current time. ...
• DATE(): Extracts the date part of a date or date/time expression. ...
• EXTRACT(): Returns a single part of a date/time. ...
• DATE_ADD() : Adds a specified time interval to a date
15. 4) "TIME FUNCTION "
The time() function extracts the time part from
a given time/datetime.
Note: This function returns "00:00:00" if expression is not a
datetime/time, or NULL if expression is NULL.
Syntax:
TIME(expression)
MySQL TIME_FORMAT() Function:
The TIME_FORMAT() function formats a
time by a specified format.
Syntax:
TIME_FORMAT(time, format)
Parameter Description
time Required. The time to be formatted
format Required. The format to use. Can be one or a combination of
the following:
