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);

6-🚩
myCars.ForEach(p => Console.WriteLine(“{0} {1:C}”, p.VIN, p.StickerPrice));

7-🚩
Console.WriteLine(myCars.Exists(p => p.Model == “745li”));

8-🚩
Console.WriteLine(myCars.Sum(p => p.StickerPrice));


9-🚩
foreach (var car in orderedCars)
{
Console.WriteLine(“{0} {1}”, car.Year, car.Model, car.VIN);
}

sharing some Interview questions #sql #advance

1. What are Window Functions?
-> A Window Function performs a calculation across a set of table rows that are somehow related to the current row. Window functions are initiated by the OVER() clause. Another important clause is PARTITION BY, which defines data partitions within a window frame. When this clause is omitted, the partition is the entire result table. Another important clause is ORDER BY. It sorts data within the window.

2. What Window Functions do you know?
-> SQL window functions can be generally divided into four categories:
a. Ranking Functions
b. Distribution Functions
c. Analytic Functions
d. Aggregate Functions

a. The Ranking functions are:
1. ROW_NUMBER() – Returns a unique number for each row within a partition; tied values have different row numbers.
2. RANK() – Ranks data within a partition; tied values have the same rank, and there’s a gap following ties (e.g. 1, 2, 3, 3, 5).
3. DENSE_RANK() – Ranks data within a partition; tied values have the same rank and there’s no ranking gap (e.g. 1, 2, 3, 3, 4).

b. The Distribution functions are:
1. PERCENT_RANK() – Returns the relative rank within a partition.
2. CUME_DIST() – Returns the cumulative distribution within a partition.

c. The Analytic functions are:
1. LEAD() – Allows accessing values from a subsequent row in relation to the current row.
2. LAG() – Allows accessing values from a previous row in relation to the current row.
3. NTILE() – Divides rows within a partition into approximately equal groups.
4. FIRST_VALUE() – Allows accessing values from the first row within a partition.
5. LAST_VALUE() – Allows accessing values from the last row within a partition.
6. NTH_VALUE() – Allows accessing the nth row within a partition.

d. The Aggregate functions are:
1. AVG() – Returns an average value for the rows in a partition.
2. COUNT() – Returns the number of values in the rows in a partition.
3. MAX() – Returns the maximum value for the rows in a partition.
4. MIN() – Returns the minimum value for the rows in a partition.
5. SUM() – Returns the sum value of the rows in a partition.
