sharing some Interview questions #sql #intermediate

1. How to select random rows from a table?
-> Using the RAND() function in combination with ORDER BY and LIMIT. In Mysql we use RAND() which returns random records from table.
SELECT * FROM table_name
ORDER BY RAND()
LIMIT 5;

2. How to find the last id in a table?
-> By using MAX(), We use following syntax
SELECT id
FROM table_name
ORDER BY id DESC
LIMIT 1;

3. How to find the values in a text column of a table that start with a certain letter?
-> Using the LIKE operator in combination with the % and _ wildcards. For example, we need to find all surnames in a table that start with "A". The query is:
SELECT * FROM table_name
WHERE surname LIKE 'A_';

⛳️LINQ in ASP .NET (short Note by Coderbaba)⛳️

⚡️LINQ: Language Integrated Query


👉🏻-it is a Query Language that is pronounced as "link" is designed and introduced by Microsoft for .NET technology that addds data querying capabilities to .NET Languages .
👉🏻-LINQ introduced in .NET 3.5 (Visual Studio 2008) using LINQ we can write Queries on Array, Collections, XML Source and Relational Databases.

👉🏻-LINQ is as same as SQL but sql can be used only on relational database but linq can be used on a wide variety of data sources like Array,Collections, XML source and Relational databases.

👉🏻-Query expressions are written in a declarative query syntax.By using query syntax, you can perform filtering , ordering , and grouping operations on data sources with a minimum of code.

👉🏻-LINQ query expressions, are similar to

⛳️LINQ is divided into 3 parts, those are:⛳️

1-LINQ to Objects : => Array and Collection
2-LINQ to XML (XLINQ): => XML Source
3-LINQ to Database: Relational Database (SQL Server)

Note:
----------------------
🚀linq to obj:
this type of programming called imperative programming.

🚀linq to database:
it is called as declarative programming.
-------------------

All LINQ query operations consist of three distinct actions:
1-Obtain the data source
2-Create the query
3-Execute the query

😎LINQ Query Expressions:
LINQ query expressions are witten in a declarative SQL like syntax.

Example:
get those student name from array which has more than 3 characters:

------------
string studentName={"Raj","Mohan","John","Sima","Tanu"};

IEnumerable<string> subset=
from n in studentName where
n.Length>3 orderby n select n;

foreach (string s in subset)
Console.WriteLine("Name:{0}",s);

-----------------------------

👉🏻-The standard query operators provide query capabilities including
*Filtering-where
*Project-select,selectMany
*Aggregation-Sum,Max,Count,Average
*Sorting-orderby
*Grouping-groupby
*...and many more



-----------------
🌎Query Expression Trees:
A query expression trees is an efficient data structure representing a LINQ expression
- type of abstract syntax tree used for storing parsed expresssions from the source code.

-Lambda expressions often translate into query expression trees.

IQueryable<T> is interface implemented by query providers (e.g. LINQ to SQL, LINQ to XML, LINQ to Obj)

IQueryable<T> objects use expression trees

--------------------------------------------

⛳️LINQ to SQL:⛳️
-----------------

Select Statement

SQL: Select * from Customer where City="India"

LINQ:
var q =from c in Customer where c.City=="India" select c;

⛳️Why LINQ Beats SQL:⛳️
-------------------
-SQL is a very old langauage invented in 1974.
since then it is been extended endlessly, but never redesigned and this has made the language messy.

-LINQ is the language with syntax of C# and Visual Basic
simpler,tidier and higher level

Ex:

SQL: select UPPER(Name) from Customer where Name LIKE'A%' Order by Name

LINQ:
var qr=from c in Customer where c.Name.StartsWith("A")
orderby c.Name select c.Name.ToUpper();

------------------

Simpler how?

ex:

💻SQL query:

select top 10 Upper(c1.Name) from Customer c1
where c1.Name LIKE 'A%' AND c1.ID NOT IN
(
select Top 20 c2.ID from Customer c2 where c2.Name LIKE 'A%' Order by c2.Name
)Order by c1.Name


💻LINQ:

var qr=from c in Customer where c.Name.StartsWith("A")
orderby c.Name
select c.Name.ToUpper();
var result=query.Skip(20).Take(10);

-------------------------------------

🏆Example code :
🧜‍♂️LINQ Query:-

1-👉🏻
var bmws = from car in myCars
where car.Make == “BMW”
&& car.Year == 2010
select car;

2-👉🏻
var orderedCars = from car in myCars
orderby car.Year descending
select car;


// LINQ method:

1-🚩
var bmws = myCars.Where(p => p.Make == “BMW” && p.Year == 2010);

2-🚩
var orderedCars = myCars.OrderByDescending(p => p.Year);

3-🚩
var firstBMW = myCars.OrderByDescending(p => p.Year).First(p => p.Make == “BMW”);
Console.WriteLine(firstBMW.VIN);

4-🚩
Console.WriteLine(myCars.TrueForAll(p => p.Year > 2007));

5-🚩
myCars.ForEach(p => p.StickerPrice -= 3000);
