The database is complicated. Oracle is used for GIS. Usually, SQLite or Access is used for some gadgets, and MYSQL is also used for ASP. NET.

I quickly forgot some of MSSQL, so I decided to review some of them.

It took a few hours to do this, starting from the simplest. I read all sorts of things or concepts and wrote some SQL statements in the examples.

Then I sorted it out a little and made up some very simple components of the current series.

I didn't explain too much about various concepts. I just used SQL to explain how to use these concepts.

SQL is also very simple, not long, easy to understand.

Because I do not have other sample databases (both NorthWind and AdventureWorks are good sample databases ),

In this series, I create tables temporarily, write some data temporarily, and delete the data after use!

So if you are looking at advanced SQL technology, you have come to the wrong place!

Let's take a look at the various concepts!

If you want to understand various concepts through various SQL statements and then want to use them further, congratulations, I think you can come and have a look!

The series is divided into six parts:

MSSQL Literacy Series (1)-CREATE, ALTER, DROP

MSSQL Literacy Series (2)-INSERT, UPDATE, DELETE

MSSQL Literacy Series (3)-SELECT

MSSQL Literacy Series (4)-system functions

MSSQL Literacy Series (5)-constant, variable, operator, process control

MSSQL Literacy Series (6)-exceptions, things, functions, stored procedures
