15.1.12 CREATE DATABASE Statement

CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE .

An error occurs if the database exists and you did not specify IF NOT EXISTS .

CREATE DATABASE is not permitted within a session that has an active LOCK TABLES statement.

Each create_option specifies a database characteristic. Database characteristics are stored in the data dictionary.

The CHARACTER SET option specifies the default database character set. The COLLATE option specifies the default database collation. For information about character set and collation names, see Chapter 12, Character Sets, Collations, Unicode .

To see the available character sets and collations, use the the SHOW CHARACTER SET and SHOW COLLATION statements, respectively. See Section 15.7.7.3, “SHOW CHARACTER SET Statement” , and Section 15.7.7.4, “SHOW COLLATION Statement” .

The ENCRYPTION option, introduced in MySQL 8.0.16, defines the default database encryption, which is inherited by tables created in the database. The permitted values are 'Y' (encryption enabled) and 'N' (encryption disabled). If the ENCRYPTION option is not specified, the value of the default_table_encryption system variable defines the default database encryption. If the table_encryption_privilege_check system variable is enabled, the TABLE_ENCRYPTION_ADMIN privilege is required to specify a default encryption setting that differs from the default_table_encryption setting. For more information, see Defining an Encryption Default for Schemas and General Tablespaces .

A database in MySQL is implemented as a directory containing files that correspond to tables in the database. Because there are no tables in a database when it is initially created, the CREATE DATABASE statement creates only a directory under the MySQL data directory. Rules for permissible database names are given in Section 11.2, “Schema Object Names” . If a database name contains special characters, the name for the database directory contains encoded versions of those characters as described in Section 11.2.4, “Mapping of Identifiers to File Names” .

Creating a database directory by manually creating a directory under the data directory (for example, with mkdir ) is unsupported in MySQL 8.0.

When you create a database, let the server manage the directory and the files in it. Manipulating database directories and files directly can cause inconsistencies and unexpected results.

MySQL has no limit on the number of databases. The underlying file system may have a limit on the number of directories.

You can also use the mysqladmin program to create databases. See Section 6.5.2, “mysqladmin — A MySQL Server Administration Program” .

7. Rewrite the last questions using an inner join and alias for table names.

8. List last name, first name, and phone of Students who have purchased a Textbook that was supplied by a bookstore with a name that begins with a given English letter. (Use subquery).

9. Rewrite the previous question using an inner join of the tables and alias for table names.

10. List the total “sum” of textbook prices for each student in descending order by last name and first name, class, textbook description AND total purchases for a given year. Use an inner join for the tables. NOTE: The business rule for the STUDENT_TEXTBOOK table assumes that a student will only purchase one textbook at a time.

Assignment Operator in MySQL

Back to: MySQL Tutorials for Beginners and Professionals

Assignment Operator in MySQL with Examples

In this article, I am going to discuss Assignment Operator in MySQL with Examples. Please read our previous article where we discussed SET Operators (UNION, UNION ALL, INTERSECT, & EXCEPT) in MySQL  with examples.

The Assignment Operator in MySQL is used to assign or compare a value to a column or a field of a table. The equal sign (=) is the assignment operator where the value on the right is assigned to the value on the left. It is also used to establish a relationship between a column heading and the expression that defines the values for the column.

Example to understand Assignment Operator in MySQL

Let us understand the MySQL Assignment Operator with some examples. We are going to use the following Product table to understand the Assignment Operator.

Please execute the below SQL Script to create and populate the Product table with the required sample data.

Example: Update the Price of each product by adding 10

Now we will update the Price column of the Product table by using the equals operator as an assignment. Following is the SQL statement.

UPDATE Product SET Price = Price + 10;

Once you execute the above Update statement, now verify that the Price column value in the Product table is updated as shown in the below image. SELECT * FROM Product; will give you the following result set.

Here, you can observe the Price column has been updated by raising the existing prices by adding 10. Also, we can use the same operator for comparing values. Following is the example:

UPDATE Product SET Price = Price * 1.02 WHERE ProductId = 6;

Let’s see the updated table: SELECT * FROM Product; will give you the following output.

Here we are updating the Price column of the Product table where the ProductId is 6. And you can observe that only the Price with ProductId =6 has been updated.

Assigning Variables using Assignment Operator in MySQL

There are two ways to assign a value:

• By using SET statement: Using SET statement we can either use := or = as an assignment operator.
• By using SELECT statement: Using SELECT statement we must use := as an assignment operator because = operator is used for comparison in MySQL.

SET variableName = expression; where the variable name can be any variable created. SELECT FieldName = expression; where field name can be any given name.

Example: Using SET Statement in MySQL

SET @MyCounter = 1; SELECT @MyCounter;

In this example, first, we have created a variable @MyCounter and then we are using the assignment operator to set @MyCounter to a value returned by an expression.

Example: Using SELECT Statement in MySQL

Let’s get the most expensive item from the Product table and assigns the Price to the variable @ExpensiveItem. Following is the SQL Statement.

SELECT @ExpensiveItem := MAX(Price) FROM Product;

When you execute the above statement, you will get the following output.

In the next article, I am going to discussed Constraints in MySQL with Examples. Here, in this article, I try to explain Assignment Operator in MySQL with Examples. I hope you enjoy this article.

SQL Assignment Help, MySQL Database Homework Help

Every programmer is familiar with MySQL, because it’s the most widely used open-source relational database management system, and the second most used overall. It has a graphical user interface and command-line interface (such as MySQL Workbench), operational on many systems (Windows, Linux, and Mac), and has many features the same as commercial database management platforms such as Microsoft MSSQL and Oracle SQL. You might find yourself lost in all the tables you have to manage in the MySQL database (including stored procedures, triggers, etc.). Luckily we are here to provide students with SQL homework help. We offer a wide range of services and help with SQL:

• Planning and constructing new database (ERD using Microsoft Visio or draw.io)
• Managing database connections (e.g. connection to MS Access)
• Optimizing existing database (especially design!)
• Backup and restore database
• Procedures, Triggers, timers
• Reports, Forms, Queries, VBA...

And help with any other issues you might face… So if you wonder who can "help with my SQL homework" -  WE CAN !

There is a wide range of possibilities for completing SQL assignments while incorporating other programming languages. On the other hand, there are not so many options for saving data: simple text files, XML, or relational databases. The best option is usually MySQL. Every server most commonly uses some SQL variant as their database platform, because most are free and reliable. In case you need help with SQL project setting up ERD – it is one of the database homework help services we provide. We will solve every problem you face in the SQL database at an affordable price.

We also can help you with  Murach’s MySQL course.

SQL Assignments Are Easier with Our Help

Our team consists of experienced programmers, data analytics, information specialists who hold degrees in their fields. If you are in the middle of a difficult SQL database project, specifically stuck with a certain bug, Homework Help Online is happy to share the experience we have gained in many of years. Why would you need to puzzle yourself with such a thing as the database procedures or triggers? There’s a better option – ask the questions and get the answers, or just simply submit your task, fill in the requirements, and wait for your SQL assignment help to proceed. This is why the students like us. In case you don’t have enough time for completing your task (it is a common issue that one gets stuck with a database bug the last night!), a quick tip is the best option.

Typical university SQL assignment (full project) consists of:

• Business needs analysis, based on some partial information provided in the requirements (a.k.a. business rules)
• ERD design and drawing, including primary/foreign keys, relation types, and data types
• Database construction - a script of the correct order of tables CREATE queries and relations assignments
• Filling in the example data (not too much, but enough for the SELECT queries)
• Writing SELECT queries. This might be simple or very challenging, depending on the course you take
• Extra credit: writing triggers and procedures (this part is rare in our experience, however, it is important in the real systems)

Overall, all this struggle most likely leads you onto a great career path. Once mastered, database technology is used not only in websites but also in various ERP (enterprise resource management) projects. You don't deal with it while studying in university, but it might be a nice surprise to understand how the industry really operates. Starting from simple SQL projects and gaining momentum with database assignment help leads to an IT career path you never expected.

Frequently Asked Questions

Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here .

The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):

Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.

We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.

No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.

It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.

No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.

Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.

MySQL Sample Database

We use the classicmodels database as a MySQL sample database to help you work with MySQL quickly and effectively.

The classicmodels database is a retailer of scale models of classic cars. It contains typical business data, including information about customers, products, sales orders, sales order line items, and more.

We’ll use this sample database in our MySQL tutorials to demonstrate a wide range of MySQL features, from simple queries to complex stored procedures .

Download MySQL Sample Database

You can download the sample database from the following link:

The download file is in ZIP format, so you’ll need a zip program to unzip it. You can download a free zip program at www.7-zip.org .

After uncompressing the sampledatabase.zip file, you can load the sample database into the MySQL database server by following the tutorial on how to do so.

MySQL Sample Database Schema

The MySQL sample database schema consists of the following tables:

• customers : stores customer’s data.
• products : stores a list of scale model cars.
• productlines : stores a list of product lines.
• orders : stores sales orders placed by customers.
• orderdetails : stores sales order line items for every sales order.
• payments : stores payments made by customers based on their accounts.
• employees : stores employee information and the organization structure such as who reports to whom.
• offices : stores sales office data.

The following picture illustrates the ER diagram of the sample database:

You can download the MySQL sample database ER diagram in PDF format from the following link:

Download MySQL Sample Database Diagram PDF A4

We recommend printing out the ER diagram and placing it on your desk to help you become familiar with the schema as you learn MySQL.

Database management systems are today's most reliable mean to organize data into collections that can be searched and updated. However, many DBMS systems are available on the market each having their pros and cons in terms of reliability, usability, security, and performance. This paper presents a comparative study on the performance of the top DBMS systems. They are mainly MS SQL Server 2008, Oracle 11g, IBM DB2, MySQL 5.5, and MS Access 2010. The testing is aimed at executing different SQL queries with different level of complexities over the different five DBMSs under test. This would pave the way to build a head-to-head comparative evaluation that shows the average execution time, memory usage, and CPU utilization of each DBMS after completion of the test.

O presente artigo mapeia e analisa as primeiras narrativas sobre o surgimento do novo coronavírus elaboradas pelos usuários brasileiros no Twitter. Para isso, coletamos no Twitter, por meio de big data, as mensagens contendo a palavra coronavírus (visto que esta era o único termo assertivo sobre a Covid-19), entre os dias 30 de dezembro de 2019 a 21 de janeiro de 2020. Por meio de mineração dos dados, identificamos 10.661 postagens em português. Observamos que as narrativas sobre a Covid-19 vão formando uma cronologia, que conceituamos de timeline discursiva de redes de narrativa, em que é possível estudar as mudanças da opinião pública, a partir dos léxicos que entram e saem da arena política das redes sociais. Foi a partir dessa metodologia temporal que concluímos que viver a incerteza, o medo do desconhecido, é a base emocional comum que pauta o comportamento de quem passou a se informar e conversar nas redes sociais sobre as características e os impactos da Covid-19.

MySQL is a popular relational database management system that allows users to create and manage databases. As we know databases are containers for our tables where we store our data creating a database is a crucial task.

In this article, we are going to learn how we can create databases in the MySQL database management system through the command line client tool and the MySQL Workbench application. We will provide a step-by-step tutorial to create databases in both of these applications. So deep dive into this article and master how to create databases in MySQL.

MySQL CREATE DATABASE

Creating a database is one of the most fundamental tasks while working with MYSQL. A database serves as a container for tables, views, procedures, and several other database objects. The CREATE DATABASE statement is used in MYSQL to create a new database that will store all the tables that the user will create to store the data. To create a database the following syntax is followed:

CREATE DATABASE [IF NOT EXISTS] Nameof_database [CHARACTER SET Nameof_charset] [COLLATE Nameof_Collation];

• First, the user will have to specify the name of the database he/she wants to create after the CREATE DATABASE [IF NOT EXISTS] statement. The IF NOT EXISTS statement checks if there is already a database of the same name provided by the user. If there already exists a database of that name then an error message is generated.
• The CHARACTER SET field is an optional value that defines the name of the character set to store every character in the string. Various types of character sets are supported in MySQL however if the user skips to provide this value then the default character set is used by MySQL.
• The COLLATE field is also an optional value that is used to compare the characters in a particular character set.

Methods to Create a Database in MySQL

There are mainly 2 ways through which MYSQL allows the users to create a database, through the MYSQL command line client and MYSQL Workbench Application.

1. Create a Database Using the MySQL Command Line Client

The command line client comes as an default tool when you install MySQL on your system .You can follow this article if you want a step by step guide to install MYSQL on your systems.

The MYSQL command line client is a command line interface that allows the users to directly interact with the MYSQL database server directly through the command. It provides a text based environment to the users for executing the SQL queries directly and allows the users to manage their databases as well. To create a database through the MYSQL command line client follow the below steps:

1. Search for MYSQL Command line Client in start.

2. Open the application and then Enter your password.

3. Run the following command to check the existing databases in the system.

All databases present in the system

4. After that run the following command to create database of your choice.

If you see the following output then you can ensure that your database was successfully created.

5. Again run the SHOW Databases command and you will see your database is created.

6. Run the following command to use the database you have just created.

2. Create Database using the MySQL Workbench Application

You can follow this article if you want to install MYSQL Workbench on your systems.

The MySQL workbench is a visual database design and management tool that provides a user friendly Graphical user interface(GUI) to the users through which they can interact with the MySQL database directly. This application is beneficial for those users who prefers a visual approach for development of databases rather than the command line interfaces. To create a database through MySQL Workbench follow the below steps:

1. Search for MySQL workbench in start.

2. Click on the following icon to create a local instance for your database.

3. Enter Local as your connection name and click on the Test connection button.

4. Enter your Password. The password should be the same which you set during the MYSQL installation.

5. If the connection was successful then you will see the following output.

6. Click on the Local instance you created .

7. Click on this icon to create the database schema.

9. Click on the apply button don’t change any default settings here.

10. Click on the finish button to finish the database craetion.

11. You will be able to see your created database on the left panel of your screen.

12. Right click on the database you created and click on set as Default Schema to use your database. Now your database is ready to use.

In this article we have learned how we can create databases in MYSQL. We have explored 2 methods step by step which allows the users to create databases in MYSQL. The choice of method completely depends on the user, if the users is not comfortable with the command line environment then they can use the second method of MYSQL workbench to create the databases they want. We hope this article has helped you to learn about the CREATE Database statment in MYSQL.
