Navicat is also compatible with cloud databases, intuitive, and graphically powerful. Data Grip is another tool, also available for Linux, to create and modify database objects. With Data Grip, you can add, edit, remove, and clone data rows. It was designed to browse and search data easily. Data Grip features a user-friendly interface to add and edit tables, indexes, columns, and more.

It also provides a smart code completion function, code supervision, and on-the-fly error warning with quick fixes capabilities. This is an excellent tool to manage databases, tables, relations, columns, indexes, users, and more. With phpMyAdmin, you can manage multiple servers, create graphics of your database, address complex queries, search globally, and convert data into a different format. Users simply must install it using Snap instead of manually installing the package offered on the MySQL website.

By using Snap, this process is extremely easy, and any Linux level user can achieve it by following a few steps. Keep following Linux Hint for additional Linux tutorials and tips. There are times when you do need to use bigint.

To overcome the overflow problem, signed bigint must be used. Tip 4: For small definition tables, in most cases, unsigned tinyint for primary key column is sufficient. In northwind, table categories is a definition table as it defines what categories the products can be grouped into. CategoryID column in categories table is defined as unsigned tinyint which ranges from 0 to No need to define it as unsigned int 0 to , unsigned mediumint 0 to , or unsigned smallint 0 to because we are certain that we will never have more than categories.

If we only look at CategoryID in categories table itself, it does not seem worthwhile to be bothered. But if we look at products table where CategoryID is used as foreign key column, it does look extremely helpful to use tinyint when taking into account the efficiency of query performence in JOINs between categories and products table as well as data storage efficiencies.

If you are certain that your database is only used to store data in English, you don't need utf8 character set. In terms of data storage, not all utf8 characters use the same number of bytes and can require up to three bytes per character. That means UTF8 reservs more spaces to store data than latin1. Also comparison and sorting for utf8 data use more system resources than other character sets. This is because bit data type can be any number between 1 to Data range for signed tinyint is to The unsigned tinyint range is 0 to The best practice is create an enum data type with two values only - enum 'y','n'.

In our Northwind MySQL database , we defined Discontinued column in products table as enum data type with two values only: y for yes and n for no. The two main string data types are char and varchar. Char data type is a fixed-length string that is always right-padded with spaces to the specified length when stored.

Varchar data type stores variable length of string value. For example, CategoryName is defined as varchar 15 which is variable string of 15 characters. The category name Beverages uses only 9 character space. But if you define the column as char 15 which is fixed length string of 15 characters, the category name Beverages will occupy 15 character space even though it only has 9 characters. There will be 6 right-padded spaces to the end of the name Beverages. Use char data type only if you are centain that the column always stores fixed length of data.

For example, MD5 hashed value is always character long. In this case, it's preferable to define the column as char 32 rather than varchar 32 or some other length. Index created on a char column makes queries slighly more efficient than index created on a varchar columns. More on database indexes later. I use MD5 hashed value for storing passwords in a table.

When verifying the password submitted by a user, the submitted password is MD5 hased and then the hased value is compared with the hased value stored in the table. If they match, the user is a legit user. Tip 8: When creating date and time type of data, store them as integer in your MySQL table rather than date or datetime data type. The advantages are mainly related to coding flexibility, easiness of data comparison, and increased query performance with indexes on integer columns.

Because in PHP we can convert date and time to Unix timestamp value which is a long integer containing the number of seconds between the Unix Epoch January 1 GMT and the time specified, we can store the long integer in our column for date and time related data. When using the column data, we can convert them back to the date and time format for displaying purpose by using the Date and Time Functions in PHP. These integer values are also extremely easy for calculation purpose when we need to add or substract certain time from it.

For example, the date and time has a timestamp value which is the number of seconds since January 1 GMT. To add one day to , we convert one day to seconds 1 x 24 x 60 x 60 and then add seconds to We then convert back to date and time format for displaying - we got Tip When you create a column to store IP addresses, always define it as unsigned interger data type rather than dotted representation of a network address string e. This can grealy imporve query performance when the column is searched WHERE clause , joined to another column, or sorted.

It also makes IP range calculation and comparison much easier. This function converts dotted representation of a network address string such as ' A blob data type can be used to store binary data such as media files photos or other very large non text data in MySQL database. Blob data is large and can increase database size quickly. A way to get around this problem is store the media files in file directory system and only store their filenames in database.

If, for security reasons, you need to protect the BLOB data, it's preferrable to store them in database tables rather than storing in file systems. For example, you create a photo album on a social networking site and share it with friends.

If the photo is stored in a table, before you retrieve it from the table, you can verify if the viewer has the privilege to view it. If the viewer does not have the privilege, you display a message to indicate the photo can't be viewed.

But if the photo is stored on disk, as long as the photo's URL is known, anyone can view it on the Internet.

MySQL Workbench is an open-source, fast, reliable, and highly scalable database management system. It also offers a graphical interface to work with the databases in a structured way. The installation process is similar to other operating systems. Open the MySQL website on a browser. It will ask for permission; when it does, click Yes. The installer will then open. Now, it will ask to choose the setup type. Here, select Custom. Click on the Next button.

Once the product is ready to configure, click on Next. Under Type and Networking, go with the default settings and select Next. The two main string data types are char and varchar. Char data type is a fixed-length string that is always right-padded with spaces to the specified length when stored.

Varchar data type stores variable length of string value. For example, CategoryName is defined as varchar 15 which is variable string of 15 characters.

Yes, there is a gotcha which is related specifically to MySQL. It caught me a couple of times. Let's do an experiment to illustrate how this gotcha can easily occur. First, let's create a table called gotcha in SQLyog. In this table, we created four columns with data type of int, mediumint, smallint, and tinyint. Add integer 5 for all 4 columns. Tip 5: Only use UTF8 character set where you need it. When we insert or update a product, we can simply use the character y or n to get the job done.

Tip 9: When storing current date and time in a table, always store GMT time.
