I challenge you to find in a single course these 3 very important chapters on SQL Server :

◉ Chapter 1 : Transact SQL for the absolute beginner and also experienced developers (10 hours of class)

• Let's start by installing SQL Server and management studio on your workstation.

• The creation and definition of a database and a table.

• Let's start playing with data with SELECT,UPDATE,INSERT and DELETE

• Discover the column aliases and tackle the specificity and secrets of LIKE and TOP.

• Learn how to remove duplicates with the DISTINCT and discover the Comparison operators = != and Copying a table with the SELECT INTO.

• Let's talk about the IN, NOT IN, IS and IS NOT operators, and Sort your data with ORDER BY.

• Discover aggregate functions with MIN MAX and AVG and the two operators AND,OR.

• Let's discover the specificity of COUNT and SUM and how to SELECT a range of data with the BETWEEN and Group several results with the GROUP BY

• A long chapter of 1h30 minutes on JOINS with INNER JOIN,LEFT/RIGHT JOIN FULL OUTER JOIN and so on..

• Let's discover the specificity of UNION and UNION ALL, and the LEFT and RIGHT function.

• Let's go even further with Transact SQL with the IIF,CASEWHEN,OFFSETFETCHNEXTROWS and CHOOSE.

• Let's look at the conversion functions through CAST and CONVERT, TRY_CAST and TRY_CONVERT.

• Let's approach the DATE type functions with DATEADD,DATEDIFF,GETDATE (), EOMONTH ...

• Let's deepen our knowledge of TSQL even more With IF/ELSE, STRING SPLIT,STUFF,MERGE…

• The creation and definition of a view and Stored Procedure,function, schéma and trigger.

• A very long chapter of 1h30 minutes on RANKING functions such as ROW_NUMBER, OVER and PARTITION BY, ROWS /RANGE UNBOUNDED PRECEDING, FIRST and LAST VALUES, LAG and LEAD,ROW_NUMBER, DENSE _RANK, RANK, NTILE.

• We will discover a one hour course on CTE (common table expression). So powerful and so little known (I still don't understand by the way) and the derived table.

• Do you know the difference between Temporary tables, Variable tables and Global tables?

◉ Chapter 2: The complete administration of a SQL Server (11 hours of class)

• Tackle BACKUP and RESTORE for 3 hours, we will see in detail in this course, how to set up a robust and reliable strategy, to guarantee your data on a production server.

• In another 2 hour course, we will learn how to detect and repair corruption on a database. Did you know that Microsoft logs over 1000 support cases per day regarding corruption! And you, how would you react in case of corruption?

• We will also discuss during 3 hours, the configuration and modification of your database on SQL. Did you know that a bad Autogrow set on your database, can make you lose 60% of your performance?Do you know the TRUSTWORTHY or DB_CHAINING option? Everything is covered in this course, and believe me, you will be surprised at the number of options on a DB that SQL Server offers.

• Administration rhymes with precaution, and therefore of course with security. We will discuss security and privilege management during 2 hours. We will learn how to set up a robust and secure SQL server.

• We will cover a long chapter on the different isolation modes (READ COMMITED, SERIALIZABLE, SNAPSHOT...), we will also see the different types of constraints (PK,FK,CHECK,UNIQUE...), as well as SEQUENCES, and IDENTITY.

• We will also discuss the change data capture (CDC), many new features released on SQL Server 2016 such as Row Level Security, Dynamic Data Masking (DDM), Temporal Data.

  
  

◉ Chapter 3: How to improve performance on your production SQL server (4 hours)

• If we are talking about performance, we will of course be talking about indexes. This is a good thing because it will be covered in this chapter for 4 hours. A good implementation of your indexes can really save your performance on your SQL server. I strongly advise you to look at this chapter, to perhaps avoid going into huge costs of buying servers, which may not be necessary.

• Do you know SARGABLE queries?I let you discover it in this chapter, to rewrite your SQL queries, in a better way, and thus of course, better performance.

  
  

◉ Chapter 4: Come and take a virtual interview through these 40 questions and 40 theoretical answers.

• Start out more confident by tackling all these theoretical questions, so that you can face an interview on SQL.

• You are a Java developer or Python for example, you go to an interview, you don't really know what to review beforehand, this is a summary of the most frequently asked questions.

• For example : What is a primary key ? what is an index? What is the difference between OLAPand OLTP ? Do you know the COALLESCEfunction ?or how do you remove duplicates with your query ?

  
  

  
  

There will be many new sections added in 2021, of course if you have already purchased this course, these new modules will be free for you :

• How to administer your SQL server with powershell? (3 hours of class)

• Improve the performance of stored procedures (2 hours of class)

• Let's go together on SQLAzure ! (3 hours of class)

• Of course there are more than 100 exercises and corrections in this course.

This course will have an estimated duration of between 30 and 40 hours once completed.
