Netbeans/C3/Connecting-to-a-MySQL-Database/English-timed

Time	Narration
00:00	Hello everyone.
00:02	Welcome to the tutorial on 'Connecting to a MySQL Database'.
00:07	In this tutorial, we will look at:
00:09	* Configuring MySQL server properties
00:14	* Starting the MySQL server
00:17	* Creating and connecting to the database
00:20	* Creating database tables, under which we will explore two methods:
00:26	# using the sql editor
00:29	# using the create table dialogue and finally,
00:33	* Running an SQL script.
00:37	For this demonstration, I am using the Linux Operating System Ubuntu v12.04
00:44	and Netbeans IDE v7.1.1.
00:48	You also need the Java Development Kit (JDK) v6
00:54	and MySQL database server.
00:57	To learn this tutorial, basic understanding of database management is necessary.
01:03	To know more, watch PHP and MySQL spoken tutorials on the link shown.
01:10	Other standard programming terminologies have been used in this tutorial.
01:16	This tutorial demonstrates how to setup a connection to a MySQL database from the Netbeans IDE.
01:24	Once connected, we will work with MySQL in the IDE's Database Explorer.
01:31	Let us switch to the IDE now.
01:36	Netbeans IDE comes bundled with support for the MySQL RDBMS.
01:42	Before you access MySQL database server in Netbeans, you must configure the MySQL server properties.
01:51	Right-click the Databases node in the Services window.
01:56	Choose Register MySQL Server to open the MySQL server properties dialogue-box.
02:05	Confirm that the Server Host Name and the Port are correct.
02:10	Notice that the IDE enters localhost as the default server host name.
02:18	3306 is the default server port number.
02:23	Enter the Administrator Username if not displayed.
02:27	On my system, the Administrator Username is root.
02:33	Enter the Administrator password.
02:36	On my system, the password is blank.
02:40	Click the Admin Properties tab at the top of the dialog-box.
02:45	This allows you to enter information for controlling the MySQL server.
02:51	In the Path/URL to admin tool: field,
02:56	type or browse to the location of your MySQL Administration application.
03:02	On my system, the location to the tool is /usr/bin/mysqladmin.
03:12	Type any arguments for the admin tool in the Arguments field.
03:18	This can also be left blank.
03:22	In the Path to start command: field,
03:25	type or browse to the location of the MySQL start command.
03:29	On my system it is: /usr/bin/mysqld_safe.
03:38	Type any arguments for the start command in the Arguments field.
03:42	Here, I will type: -u space root space start.
03:51	In the Path to stop command:,
03:54	type or browse to the location of the MySQL stop command.
03:58	This is usually the path to mysqladmin' in the bin folder of the MySQL installation directory.
04:06	On my system, this is: /usr/bin/mysqladmin.
04:14	If the command is mysqladmin, in the Arguments field, type: -u space root space stop.
04:27	When finished, the Admin Properties tab should resemble what is shown on the screen.
04:33	Click OK.
04:36	First ensure that the MySQL database server is running on your machine.
04:42	The MySQL server node in the Service window indicates whether the MySQL database server is connected.
04:52	After making sure that it is running, right-click the Databases >> MySQL server node and choose Connect.
05:05	When expanded, the MySQL server node displays all the available MySQL databases.
05:13	A common way of interacting with databases is through an SQL Editor.
05:19	Netbeans has a built-in SQL Editor for this purpose.
05:23	You can access this by right-clicking on the connection node.
05:29	Let us now create a new database instance using the SQL Editor.
05:34	In the Services window, right-click the MySQL server node and choose Create Database.
05:44	In the Create Database dialogue, type the name of the new database.
05:50	I will name this mynewdatabase.
05:56	You can also grant full access to a given user.
06:01	By default, only the admin user has the permissions to perform certain commands.
06:08	The drop-down list allows you to assign these permissions to a specified user.
06:13	It is a good practice to grant users most permissions, except to drop tables
06:18	and allow users to modify only those databases that are created by their application.
06:25	But for now, we will leave the check-box unselected.
06:30	Click OK.
06:34	Let us now create tables, populate them with data and modify the data maintained in tables.
06:41	mynewdatabase is currently empty.
06:44	Let us explore the first method to input data in the tables.
06:48	In the Database explorer, expand the mynewdatabase connection node.
06:58	There are three sub folders:
07:00	Tables, Views and Procedures.
07:04	Right-click the Tables folder and choose Execute Command.
07:11	A blank canvas opens in the SQL Editor in the main window.
07:16	Let us type a simple query in this SQL editor.
07:30	I have now typed a simple query in the SQL editor.
07:36	This is a table definition for the Counselor table we are about to create.
07:42	To execute this query, either right-click the Run SQL icon in the task bar at the top
07:51	or right-click within the SQL Editor and choose Run Statement.
08:00	The IDE generates the Counselor table in the database.
08:04	You can see this message in the Output window
08:12	which says that the command was executed successfully.
08:17	To verify these changes, right-click the Tables node in the Database Explorer.
08:25	Choose Refresh.
08:28	This updates the current status of the specified database.
08:32	The new Counselor table now displays under the Tables option.
08:40	If you expand the Table node, you can see the columns that you created.
08:46	Let us now explore the next method to input data in the tables,
08:51	i.e. using the Create Table Dialog.
08:54	In the Database Explorer, right-click the Tables node and choose Create Table.
09:03	The Create Table dialogue opens.
09:06	In the Table name text field, type "Subject".
09:13	Click on Add Column .
09:16	In the Add Column dialogue, type "id" in the Name field.
09:22	Choose SMALLINT for data-type from the Type drop-down menu.
09:30	Select the Primary Key check-box in the Add Column dialog-box.
09:35	This is to specify the primary-key for your table.
09:39	Note that when you select the Key check-box, the Index and Unique check-boxes are automatically selected;
09:49	also the Null check-box is deselected.
09:53	This is because primary-keys are used to identify an unique row in the database.
09:59	Click OK.
10:03	Repeat this procedure to add the remaining columns, as shown on the screen.
10:09	We have now created a table named Subject that will hold data for Name, Description and Counselor ID.
10:20	Click OK.
10:23	By running SQL queries on a database, we can add, modify and delete data maintained in database structures.
10:32	Let us add a new record to the Counselor table.
10:35	Choose Execute Command from the Tables node context menu.
10:43	A new SQL Editor opens in the main window.
10:47	In the SQL Editor, let us type a simple query.
11:00	To execute this query, right-click within the source editor and choose Run Statement.
11:07	Let us now verify if the new record has been added to the table.
11:12	Right-click the Counselor table and choose View Data.
11:18	A new SQL Editor opens in the main window.
11:21	A query to select all data from the table is automatically generated.
11:27	The results of this statement are displayed in a table view below the workspace.
11:41	Note that a new row has been added with the data we just supplied.
11:46	We can also run an external SQL script directly in the IDE.
11:52	I have a SQL query here for demonstrative purposes.
11:59	This script creates two tables similar to the ones we have just created.
12:04	i.e. Counselor and Subject.
12:09	Because the script overwrites these tables,
12:12	we will delete these two tables if they already exist.
12:16	To delete tables, right-click on the Counselor table
12:21	and choose Delete.
12:24	Click Yes in the Confirm Object Deletion dialogue-box.
12:31	Repeat the same for the Subject table.
12:38	Now, open the existing SQL query file from your system.
12:43	From the File menu, choose Open File.
12:48	Browse to the location containing this file.
12:54	The script automatically opens in the SQL editor.
12:59	Make sure the connection to mynewdatabase is selected.
13:03	Check this from the connection drop-down in the toolbar at the top of the editor.
13:13	Click the Run SQL button in the task bar.
13:17	And the script is executed against the selected database.
13:22	Right-click the mynewdatabase connection node and choose Refresh.
13:28	This updates the database component to the current status of the specified database.
13:34	Right-click on any of these tables now and choose View Data.
13:41	And below the workspace, you can see the data contained in the new tables.
13:52	In this tutorial, you learnt to-
13:54	* configure MySQL on your computer
13:57	* set up a connection to the database server from the IDE
14:02	* create, delete, modify data and
14:06	run SQL queries.
14:10	As an assignment,
14:11	create another database instance with tables.
14:15	Populate these tables with necessary data to maintain your personal book library.
14:21	And run these SQL statements to view data.
14:29	I have created a similar database which maintains details of my personal movie library.
14:37	Your assignment should resemble this.
14:44	Watch the video available at the link shown on the screen.
14:48	It summarizes the Spoken Tutorial project.
