Here, you can find information regarding all the traffic your server has Received and Sent while the MySQL server been running. It also shows the maximum concurrent connections, and Failed attempts.

It is the database which stores all the information of all other databases like name of databaseS, name of tables, column data type, access privileges and so on. It is a built-in database created with the purpose of giving information about the whole database system. In information_schema tables are automatically populated by the MySQL DB server.

Give a relevant name for the database in the entry box and click the Create button. The phpMyAdmin will create tables which will be added under the newly created database.

You can add as many numbers of tables as required in one particular selected database by using the section Create table and then the select number of columns needed for any table.

The phpMyAdmin will give an option to upload an SQL file to your server. Click on the Import tab of the top screen and it will allow you to choose a file from any location. This helps in creating database or tables as written in the imported file.

Another way to run a SQL query in the database is by using Query tab. Using this you can give many search conditions, query more than one table and also sort the results. You can even easily pick all the columns needed for MySQL query by using Column drop down menus and Show checkbox.

For sorting the result set in a query in an ascending or descending order, you can use the Sort dropdown. You can also enter the criteria for the search query.
