Overview

MySQL for IU Sitehosting uses the MySQL Enterprise Backup features on a nightly schedule. These backups are retained for 14 days for service-wide disaster recovery purposes.

MySQL restoration policy

If you need to back up or restore your data for any purpose (development, transference from production to test, etc.), you should take advantage of the functionality and tools that MySQL Workbench offers (for example, mysqldump or Data Export and Import Wizard).

The Database Administration team will perform MySQL data restoration in extremely limited cases, such as data loss due to SQL injection or unforeseen corruption. Data restoration services are performed on a case-by-case basis and are subject to review and approval by administrators. In all cases, data restoration is limited to the previous night's updates. Binary logs are not active, and it is not possible to provide point-in-time recovery. Data restoration may take up to 48 business hours to process.

To request data restoration, email Tier 2 Support. Include the date and time the incident requiring data recovery occurred and the type of incident that spurred your request. You may be asked to provide information about what steps you have taken to mitigate the need for future data restoration. Staff will forward your request to the Database Administration team, who will contact you with options or further questions they may have.

Departments and owners of sites who require 24x7 data backup and restoration services are encouraged to contact the Database Administration team to discuss options, which may include creating an Enterprise MySQL instance for just that site's content and on-call data recovery services. A fee may be associated with these services.

Manually back up your MySQL for IU Sitehosting schemas

Create a backup using MySQL Workbench

Note:

Store this backup file in a manner consistent with the data classification appropriate to your site's content. Sites which store sensitive internal or critical data must be stored in secure locations.

If you're using versions of Workbench before 6.3.8, including on IUanyWare, you will have an unhandled exception when trying to export on the new system. You will be unable to export until you update Workbench.

1. Connect to your MySQL database.
2. Click on the main tool bar.
3. Select .
4. Select the tables you want to back up.
5. Under , select where you want your dump saved. By default, it will save to your Documents folder in a subfolder titled dumps.
6. Click .

   Note:

   You may get a message about a mismatch between your mysqldump.exe version and the MySQL Server version. You can update your local MySQL version or continue.

7. You now have a backup version of your site. Store this content securely in a manner consistent with your MySQL schema content's data classification.

Load a MySQL dump from MySQL Workbench

To load a MySQL dump file after a database failure or corruption:

1. Connect to your MySQL database.
2. Click on the main tool bar.
3. Select .
4. You should see a link to the default dump folder, typically your Documents folder in a subfolder titled dumps.
5. Click the and navigate to where your MySQL backup file is located, select the backup you want to load, and click .

Often, there is a need to migrate data from MySQL to external sources, which may be to a file (CSV, Excel), another database, a cloud platform, or some other external tool. The movement of data is required when you want to perform analytics on the data (which may not be possible in MySQL itself) or to move the data into a modern ecosystem for better compatibility.

This article will give you a comprehensive guide on MySQL and its key features in brief. You will also explore various methods to export data from MySQL. The primary focus of this article is the Data Export MySQL Workbench feature which will also be discussed in further sections. By the end of this article, you will gain complete knowledge about these methods and their implementation.

What is MySQL?

MySQL is an accessible and popular open-source Relational Database. It is widely used by many small and big industries when there is a need to store structured data and perform quick analytics to understand the behavior of the data.

Key Features of MySQL

Some of the most important key features of MySQL are as follows:

1. Free Source: Free and easy to use.
2. ANSI SQL: MySQL uses the standard form known as ANSI SQL with a universe of Data Analytical functions.
3. Driver availability: With the help of available drivers, it can easily integrate with many programming languages and modern tools.
4. Integration: Easy integration with operating systems.
5. Support huge databases: MySQL provides support for large databases, up to 50 million rows or more in a table. 
6. Memory Usage: The default file size limit for a table is 4GB, but this can be increased to a limit of 8 million terabytes (TB) (provided the operating system supports it).

Why exporting a database is important?

• Back up for catastrophic system failure: Exporting a database creates a backup that you can use to restore your database in case of system failure.
• Data versioning: Specific versions on your database can be saved by exporting the database from MySQL. You can analyze or restore any particular version of the database.

Methods to Export Data from MySQL

There are various ways by which you can export MySQL data, i.e., by using the in-house Data Export MySQL Workbench feature or programmatically (Python, Java, etc.) or by some other ways. Here you will look into the most popular and easy way to export the data from MySQL:

• Method 1: Data Export MySQL Workbench Feature
• Method 2: Using MySQL Commands

Learn the key benefits of automating Data Integration

Before we start discussing different methods to export data, let’s first consider the following points:

1. The schema we have defined is “test”.
2. The table name is “orders”.
3. The orders contain the following attributes:
   1. order_id: Id of the order placed.
   2. order_date: Date of the order placed.
   3. custormer_id: Id of the customer who has placed the order.
   4. order_status: Status of the order (CLOSED, PENDING_PAYMENT, COMPLETE, PROCESSING, PAYMENT_REVIEW, PENDING, ON_HOLD, CANCELED, SUSPECTED_FRAUD).

1. The MySQL Server’s process should have write access to the target folder containing the target CSV file.
2. The target CSV file must not exist.

Method 1: Data Export MySQL Workbench Feature

The Data Export MySQL Workbench feature provides an inbuilt option to export the data into CSV format.

You can download Data Export MySQL Workbench from here. Below is the step-by-step procedure on how you can utilize the Data Export MySQL Workbench feature with ease.

1. First, prepare the query and execute it to get the desired result set.

1. From the result panel, click on the Export option.

1. On the save dialog box, enter the file name, choose CSV as the file format, and click the Save button as shown by the image below.

Method 2: Using MySQL Commands

The simple way to export data from MySQL is to use the inbuilt feature of extracting the data by using the SQL approach. This command exports the data into CSV format with the specified “delimiter” and “escape characters”. 

CSV files are the best when we talk about Data Analytics because of their structured format and ease of integration with the existing available tools.

Step 1: First, we have to prepare the query which contains the desired data to be exported. Here, we are exporting the data where order_status is COMPLETED.

Step 2: Mention the optional parameters like field delimiter, field enclosing option, and execute the query using execute option in the Workbench.

1. Step 3: On successful completion of the query, the CSV will be exported to the mentioned location.

Below are the schematics for the MySQL command :

Below is the command for your reference :

SELECT order_id, order_date, customer_id, order_status
FROM test.orders
WHERE order_status = 'COMPLETE' 
INTO OUTFILE 'c:/Temp/output/Completed/orders.csv' 
FIELDS ENCLOSED BY '' 
TERMINATED BY ',' 
ESCAPED BY '"' 
LINES TERMINATED BY '
';

Conclusion

There are a variety of options in the market to migrate or export data from the MySQL server to the required destination. One of the popular in-house options among them is the Data Export MySQL Workbench feature which has been discussed in this article. Now, you have a comprehensive idea of how you can easily export data using the Data Export MySQL Workbench and SQL commands.
