We get a procedure list with the help of DMV like " Sys.objects & sys.parameters"

USE [SqlBank]

SELECT s.NAME StoreProcedure, p.NAME Parameter FROM SYS.PARAMETERS p
JOIN SYS.OBJECTS s on p.object_id=s.object_id
WHERE TYPE='P'
ORDER BY p.NAME

From the above query, we get Procedure name with parameters

To compare SQL DB objects we use Dynamic views Like  "SYS.SYSOBJECTS, "SYS.SYSCOMMENTS", "INFORMATION_SCHEMA.COLUMNS"

STEP 1
Declare local varible
DECLARE @SourceDbName SYSNAME = 'SqlBank'; -- Source Database Name
DECLARE @TargetDbName SYSNAME = 'SqlBankCore';-- Target Databse Name

DECLARE @TargetSYSCommentExecute NVARCHAR(4000);

DECLARE @InformationCommonQuery NVARCHAR(4000);
DECLARE @ExecuteSourceInformationColumn NVARCHAR(4000);

STEP 2
Declare Variable table for Objects xtypes
DECLARE @Tbl_Xtypes TABLE(xtype CHAR(2),xtypeDefination VARCHAR(1000))

INSERT INTO @Tbl_Xtypes Values

When SELECTing information from the table(s), we mostly ask for grouped data. Grouping allows us to retrieve statistical data by some columns. Grouping is very important, but sometimes it is not just enough to “generate” final information.

Sometimes we need to rotate one of the columns to be as a row without changing the result of grouped data. Long story short, transforming data from a state of rows to a state of columns is called Pivoting.

PS: All examples use Adventurework2019.

Simple example without pivot: (classical grouping)
SELECT
  SalesOrderID
, SpecialOfferID
, SUM(UnitPrice) as TotalSum
  FROM Sales.SalesOrderDetail AS SOD
  GROUP BY SalesOrderID, SpecialOfferID

In the above example, we get data grouped by SalesOrderId and SpecialOfferId. Say your manager asked for the same data but he wants to see SpeciallOfferId in the columns. So from the above example, you will have columns like [1], and [2]. The main focus is SpecialOfferId and we need to somehow rotate the column to be not a column but a row.

T-SQL provides a special table operator to implement it: PIVOT.

Before writing PIVOT, let’s see what you need to know about the internal implementation of PIVOT. You should identify 3 elements:

    What do you want to see on rows?
    What do you want to see on columns?
    What type of information should be rendered in the intersection of these columns and rows ( mostly it is your aggregate column)

Here is the syntax for implementing it,

As we learned from the article, Common Table Expression’s (CTE) use cases wider than Derived Tables and now we will implement PIVOT exactly with CTE.

WITH CTE
AS
(SELECT SOd.SalesOrderID, Sod.SpecialOfferID, UnitPrice
  FROM Sales.SalesOrderDetail AS SOD)
  SELECT SalesOrderId, [1],[2] FROM CTE
  PIVOT(SUm(UnitPrice) FOR SpecialOfferId IN ([1],[2])) AS PVT

As you can see, PIVOT is a special table expression and as a complex combination, it defines the aggregate column for the spread column. Before switching to UNPIVOT, we need to understand some limitations of PIVOT:

    We can use only one aggregate with PIVOT
    The IN clause of the PIVOT operator accepts a static list of spreading values. You need to type them manually without any magic technique.
    No way to use COUNT(*), use classical COUNT(<column name>)

Unpivot is a reverse operation for you PIVOT. If you have any table generated by u PIVOT, you can reverse this table to the “original one” with UNPIVOT.

Let’s use our query with some modifications to create a table that will store all PIVOTted data.
WITH CTE
AS
(SELECT SOd.SalesOrderID, Sod.SpecialOfferID, UnitPrice
  FROM Sales.SalesOrderDetail AS SOD)
  SELECT * INTO MyPivottedTable FROM CTE
  PIVOT(SUm(UnitPrice) FOR SpecialOfferId IN ([1],[2])) AS PVT

The above query will store all information inside new created MyPivottedTable table.

Now it is time for our magic UNPIVOT to ”restore” information to its original.
SELECT SalesOrderID,SpecialOfferID, UnitPrice
 FROM MyPivottedTable
 UNPIVOT(UnitPrice FOR SpecialOfferId IN ([1],[2])) AS UNPVT

Here is the response:

These two operators EXCEPT and INTERSECT have been introduced since SQL Server 2005 and these two returns distinct or unique values by comparing the results of two queries.

Moreover, these operators do have rules for combining result sets just like other operators like UNION and we’ll also discuss it.

That’s why in this article we’ll be showing how we can use these two operators and understand their differences.

What is INTERSECT Operator?
Fundamentally, INTERSECT operator combines two or more queries and returns unique rows or records that are the outcomes of both left and right queries.

Then it removes duplicate records as the final result set.

INTERSECT Syntax
--INTERSECT Syntax
query_expression
INTERSECT
query_expression

It is similar to the UNION operator, that’s why both queries must have the same number and order of columns, and the column data type should be the same.

Furthermore, if these rules aren’t followed an error will occur like failing conversion of data and an equal number of expressions error.

INTERSECT Operator Example
Before we can see examples, let’s try to create a table first with some data in it.
DECLARE @TBLDOGS TABLE (Id int, DogBreed nvarchar(50))
DECLARE @TBLDOG_OWNERS TABLE (Id int, OwnersName nvarchar(50),
DogBreed nvarchar(50))

INSERT INTO @TBLDOGS (Id, DogBreed)
VALUES
(1, 'German Shepherd'),
(2, 'Labrador Retriever'),
(3, 'Golden Retriever'),
(4, 'Poodle'),
(5, 'French Bulldog')

INSERT INTO @TBLDOG_OWNERS (Id, OwnersName, DogBreed)
VALUES
(1, 'Bruce Wayne', 'German Shepherd'),
(2, 'Lex Luthor', 'Golden Retriever'),
(3, 'Vandal Savage', 'Dobermann'),
(4, 'Maxwell Lord', 'Dachshund'),
(5, 'Simon Stagg ', 'Poodle'),
(6, 'Elon Musk', 'German Shepherd')

SELECT * FROM @TBLDOGS
SELECT * FROM @TBLDOG_OWNERS

Output

OK, so everything has been set up. Let’s show how we can use the INTERSECT operator.
SELECT DogBreed FROM @TBLDOGS
INTERSECT
SELECT DogBreed FROM @TBLDOG_OWNERS

Output

As you can see, in our example we have two tables @TBLDOGS and @TBLDOG_OWNERS. Going to the data of the two tables, @TBLDOGS have German Shepherd, Labrador Retriever, Golden Retriever, Poodle, and French Bulldog.

While @TBLDOG_OWNERS have German Shepherd, Golden Retriever, Dobermann, Dachshund, Poddle, and German Shepherd.

The intersection of the two tables resulted in a German Shepherd, Golden Retriever, and Poodle.

What is EXCEPT Operator?
Fundamentally, EXCEPT operator subtracts a query result set from another query result set.

In other words, it returns unique rows or records from the left query that doesn’t appear or are not found on the right query.

EXCEPT Syntax
--EXCEPT Syntax
query_expression
EXCEPT
query_expression

Moreover, both queries must have the same number and order of columns, and the column data type should be the same.

Furthermore, if these rules aren’t followed an error will occur like failing conversion of data and an equal number of expressions error.

EXCEPT Operator Example

Data about dogs from the previous example, we’re still going to use here.

To lessen confusion I’ll be posting again the data sample of dogs.
DECLARE @TBLDOGS TABLE (Id int, DogBreed nvarchar(50))
DECLARE @TBLDOG_OWNERS TABLE (Id int, OwnersName nvarchar(50),
DogBreed nvarchar(50))

INSERT INTO @TBLDOGS (Id, DogBreed)
VALUES
(1, 'German Shepherd'),
(2, 'Labrador Retriever'),
(3, 'Golden Retriever'),
(4, 'Poodle'),
(5, 'French Bulldog')

INSERT INTO @TBLDOG_OWNERS (Id, OwnersName, DogBreed)
VALUES
(1, 'Bruce Wayne', 'German Shepherd'),
(2, 'Lex Luthor', 'Golden Retriever'),
(3, 'Vandal Savage', 'Dobermann'),
(4, 'Maxwell Lord', 'Dachshund'),
(5, 'Simon Stagg ', 'Poodle'),
(6, 'Elon Musk', 'German Shepherd')

SELECT * FROM @TBLDOGS
SELECT * FROM @TBLDOG_OWNERS

Output

OK, so everything has been set up. Let’s show how we can use the EXCEPT operator.

SELECT DogBreed FROM @TBLDOGS
EXCEPT
SELECT DogBreed FROM @TBLDOG_OWNERS

SELECT DogBreed FROM @TBLDOG_OWNERS
EXCEPT
SELECT DogBreed FROM @TBLDOGS

Output

Going to the data of the two tables, the EXCEPT operator resulted differently and it makes a significant difference because of what is on the left table.
Moreover, as we change the left table we have different results.
Moreover, from the example above the first result, the left query is the @TBLDOGS while the right query is the @TBLDOG_OWNERS.
While the second result, the left query is the @TBLDOG_OWNERS while the right query is the @TBLDOGS.
Let’s see the difference between EXCEPT and INTERSECT operators in the next section.

Difference Between INTERSECT and EXCEPT Operators

Remember that the Intersect operator uses an intersection that takes rows from both result sets that are common in both.

While the Except operator takes rows from the left result set but excludes the right result set that isn’t found.

Conclusion
In this article, we have learned how to use the SQL Server’s INTERSECT and EXCEPT operators and have seen some examples to understand these operators.
Moreover, we didn’t forget to show the difference between the two.
I hope you have enjoyed this article, as I enjoyed it while writing.
Till next time, Happy programming! Cheers! And Thank you!

Create Sequence in SQL
CREATE SEQUENCE Seq_AccountNumber As BigInt
Start with 100001
INCREMENT BY 1
MINVALUE 1
MAXVALUE 999999999999999999
CYCLE
CACHE;

Use Sequence in Procedure for generating numbers Like "Sbank_10001".
CREATE Proc Proc_GenerateAccountNumber
as
Declare @BnkName varchar(100)='Sbank_';
Declare @AccountNumber varchar(max);

SELECT @AccountNumber =CONCAT(@BnkName ,
 next value for dbo.Seq_AccountNumber
)
SELECT @AccountNumber as AccountNumber
Return

Now execute procedure "Proc_GenerateAccountNumber" & check output

If you want to restart Sequence Alter Sequence,
alter sequence dbo.Seq_AccountNumber Restart with 10001

Today we will look at a very common debate that occurs while developing a data access layer. This debate is to decide if we want to use stored procedures and keep our logic in the database, or if we want to use an ORM like Entity Framework and keep all logic in our middle tier C# code, using the database only as a data store. I will not be detailing the different types of ORMs and samples on using them as this information is widely available on the web. I will also not detail how to write and use stored procedures, as this information is also widely available for almost all types of databases. I will simply try to explain the pros and cons of using each and which and why I think it is a better solution.

What are Stored Procedures?
Let us begin by identifying what stored procedures are. Stored procedures are commonly used artifacts of relational databases, like SQL Server, Oracle, etc. These can include code to manipulate the data and are efficient in selecting, processing, and sending back data to the front-end application. These are written using SQL language, which is easy to understand and learn. Some of the major advantages of using stored procedures are that these are compiled, optimized, and run by the database engine and so can perform very quickly. For this reason, I have seen some architects strongly push the use of stored procedures.

What is an ORM?
An ORM means object relational mapping. This method allows us to create classes to represent our database tables, and then use a context or communication class to join these classes to our database tables. Then, we can use the full power of the middle-tier programming language, like C#, to write queries to select and update the data in our tables. Of course, an ORM does not end there, and we can also create other artifacts for stored procedures, etc. We can also merge classes from multiple tables and break a single table into multiple classes. However, the main idea is to use the database mainly as a store and keep all processing logic in the middle-tier code.

What to use today? Stored Procedures vs ORM
These days we have a much-advanced landscape for both stored procedures in various databases, and also great ORMs. For example, Entity Framework Core gives us many options and is easy to understand and implement. So, what should we use? The answer is that it depends upon the particular scenario. However, I would prefer to use an ORM, as in this way we can better abstract all business and processing logic into proper classes inside our middle-tier, and use the power of all libraries, NuGet packages, etc. available at this level. This also saves us from being tied to a particular database, and in the future, we can move to another data store quite easily. However, if we need to do some heavy programming at a database level and want to fully utilize the power of the database engine, using stored procedures would be the way to go. However, in this case, we might need to commit to a particular database for a longer period, especially if we are using a SQL dialect for that particular database to write our stored procedures.

Summary
In this article we looked at what to choose to build, our data access or data process layer. The answer depends on the coder's needs, and different people will have different opinions on it. However, from my personal point of view, I prefer to keep all logic in the middle-tier. This way the logic is better abstracted, and we can use the vast number of libraries available to process the data. Also, we can retrieve data in chunks and process it using parallel programming techniques and utilize the extremely powerful hardware we have these days. This also does not tie us to any particular database.
