There's a few things I wish you hadn't glossed over: Installing MySQL, setting up a server and being able to run it from the command line, ensuring it was compatible with java and the connector and so forth because they gave me a lot of headaches and weren't covered in the video. However, all the content from about 16 minutes up until the end of the video was explained well and helped me a lot with some questions I had about what was going on in the code. My only real question is how can I get the program to open the initial connection to the server? If I don't have it open and running on the command line, the connection gets rejected by jdbc

I suggest you go over the mySQL tutorial in freecodecamp channel before watching this video. I used the database I created while watching that video on this tutorial and it worked well for me :)

[@jason12518]

yeah i have no idea what he did with cmd

Awesome tutorial for explaining the basics of integrating a MySQL locally hosted server into a java application. I do have a note however. You should be a little more specific in configuration of the connection and warn users that the username and password have to exactly match the SQL setup. or like to pause the video and write down their credentials for later use in the app because i could see some people getting lost there. I got mine up and running and was really excited to start adding custom entries on the SQL side just to run the java app and see that they would appear like magic. your breakdown of how each line of code is connected from driver>connection>statement was especially helpful, as was your reiteration that the query will be how you effectly "speak to" your database from the app. seriously thank you.

Great Example thank you.

Thank you for the great explanation. I had a question. If we can simply do the same actions from SQL directly, what is the need of using JDBC?

[@ForcedPositivityMalayalam]

JDBC works as an interface between your Java Application and your SQL Database. Say you wanted to show the table called Students on a Java GUI application, jdbc would be your option.

[@tonyblinks5879]

I was gonna ask this question but I don't know why he hasn't answered yet

[@karanupamanyu3897]

Let’s say Facebook used Java for server logic. You try to fetch some data. That request reaches the server. Now, obviously, there aren’t people reading your queries, looking them up on SQL directly, and sending the results to you. You want your servers to be able to be able to do queries, and combine it with logic to produce presentable outputs. In this case, you can use JDBC. Are you trying to stalk someone on FB? Cool, let’s check if you have the permissions to do so (logic). You do? Okay, here’s the query (SQL Data). Now let’s send the data to you (networking logic). This happens on one server request.

Well explained!

Thank you!

on Mac OSX Workbench comes without MySql server, you got to install it separately.

I am getting this exception java.sql.SQLException: Access denied for user 'port'@'localhost' (using password: YES) Can you tell me what is the issue?

[@nimasafavi8070]

I appreciate your useful video. Where can I find the code?

[@SimplilearnOfficial]

Hello, thanks for viewing our tutorial. You can find your requested dataset in the video description. Hope that helps.

[@toph_beifong]

in the last query when you looked at the min for university rank, why did Kiran show up when Raju had the lowest? Also, you said 96 when it read 98??? I'm so confused now

[@SimplilearnOfficial]

Thank you for bringing this to our attention. We’re sorry you had a bad experience. We will look into the dataset once again.

[@Charles_King1]

Do i need to create a connection every time I use a different method? I am trying to create a method to search the database and another method to update the database and im a little confused.

[@vivianmardikios8577]

please can u tell me .........what is the difference between java file input/output and jdbc?

[@エッ-p8c]

jdbc and file i/o are two different things. Jdbc is the interface between the Database management system (MySQL in this video) and the java application. File i/o is, as the name suggests, the java api used to input data in a file in the form of plain text or bytes.

[@rastaramen1536]

Good tutorial, but I'm wondering why you didn't implement reading the data from the ResultSet using specific data types and an index value instead of a loop? while (rset.next()) { String universityData = ""; int pos = 0; universityData += rset.getInt(++pos) + " "; universityData += rset.getString(++pos) + " "; universityData += rset.getString(++pos) + " "; universityData += rset.getString(++pos) + " "; universityData += rset.getInt(++pos) + " "; universityData += rset.getInt(++pos) + " "; System.out.println(universityData); } Is there a reason he didn't use this method?

[@LEONSKENNEDY91]

because 'universityData' is a string the getString method says: "Retrieves the value of the designated column in the current row of this ResultSet object as a String in the Java programming language." it retrieves the current field in the table *as a String* I believe that we would get a data type mismatch exception if we would use getInt(), because universityData is String and not Integer

[@itrig7679]

A lot of unnecessary animations, just go straight to the point, thank you anyway

Thank you for your review. We’ll strive to do better.
