Thank you very much for the second part. Most of the videos on joins doesn't include the second portion of this video where you utilize the "where" clause. Earned yourself a subscriber.
That last bit of the video was helpful to really understand the Joins since I use the 'less preferred one but more commonly used' lol didnt event realize it
I am having trouble finding help on how to do Insert Into Select w/ join feature . I have data in table 1, which describes a motorsports racing session. I have table 2 which has information about each of the riders including their bike number, team , manufacturer, name, etc. - both tables have a column Rider ID, where the Riders table (table 2) has Rider ID as the primary key, and on the Table 1 , Rider ID is the foreign key. I want to write a insert into select join statement that merges in the individual rider data such as bike number, team, manufacturer , and name - into Table 1 . Can you help me please?
Suppose you are given a relation grade points(grade, points), which provides a conversion from letter grades in the takes relation to numeric scores; for example, an “A” grade could be specified to correspond to 4 points, an “A−” to 3.7 points, a “B+” to 3.3 points, a “B” to 3 points, and so on. The grade points earned by a student for a course offering (section) is defined as the number of credits for the course multiplied by the numeric points for the grade that the student received. Given the above relation, and our university schema, write each of the following queries in SQL. You can assume for simplicity that no takes tuple has the null value for grade. a. Find the total grade-points earned by the student with ID 12345, across all courses taken by the student. b. Find the grade-point average (GPA) for the above student, that is, the total gradepoints divided by the total credits for the associated courses. c. Find the ID and the grade-point average of every student. LODI PA TUTORIAL NGA NITO PARA MAY GUIDE ME SA SUNOD NA ACTIVITY SALAMAT
You can actually notice that the amount of results when using an Inner Join is 12, and then after you removed it to use WHERE, it is 13. I was wondering what are you missing out on?
Nice Tutorial, especially when I watch it in 1.5X speed. Also, This JON example you did, is it an INNER JOIN or OUTTER JOIN? How do you distinguish these two JOINs in code?
Hey Madhur, i see that we got 12 results when we used the Join query, but we got 13 results when we used Where clause, can you explain this briefly ? is it not recommended to use where clause for this kind of queries ?
what would the query be if I wanted ALL the columns from both the tables? Do I still have to type out each column? Is there a shorter way? like Select * from both tables and join them somehow?
Hi Madhur, I am trying to create a table in sql workbench where i want create a column where i want to insert ip address but not sure which data type should i select, so could you help me with the correct data type for ip address.
If anyone here can help I tried following exact the same steps to execute the join command but it didn't work ? Is that because he populated the id column in the tutorial_info table from the old tutorial or what ?? and if we have to fetch the id column from the old tutorial, what is the syntax for inserting the remaining values (views, likes, dislikes, shares) without writing the id value ? how can we skip that?
What kind of sql is this? I'm using oracle and it's giving me error "from tutorials as t" (@6:06) where t is underlined in red, saying SQL command not properly ended. What gives?
(table).(column) = SELECT users.username, users.profiledescription,stats.postcount FROM users,stats; With Insert you do the same. INSERT INTO users,stats (users.username,users.profiledescription,stats.postcount) VALUES ('$username','$description','postcount'); You could also do: INSERT INTO users,stats (username,profiledescription,postcount) VALUES ('$username','$description','postcount'); You need to keep in mind that you can not have 2 same colum names in two tables, if you have 2 same column names you need to specify the table. 'table.username' or 'stats.username'. If you have only a "profiledescription" column inside the "users" table but NOT inside "stats" you do NOT need to type 'users.profiledescription'. @Edit, before people start crying and leaving shit comments on me, i know that Sai's comment is 1year+ old, this video is from 2014 and i still came hear and learned something. When someone watches this tutorial... he might also ask about the "Insert query"... so here is the answer (above).
I am using Oracle DB and while aliasing a table name i am unable to use AS. I had to use table alias like this " tutorial t". Is this because of Oracle dialect?
Alright, for those poor bastards out there trying to learning Kusto Query Language where tutorials do not exist, the translation would be: | join OTHER_TABLE on $right._COLUMN_NAME == $left._COLUMN_NAME This will merge the two tables where the column name is matches.

+Sonia Chavez Thanks for watching!
i don't understand why people don't like the video after watching it?
Thank you
your videoz r vryy helpful!!!
So helpful, thank you!
Great stuff!
Thank a lot 👍👍
Thanks for watching!
can you please provide the insert queries for your table.
(table).(column) = SELECT users.username, users.profiledescription,stats.postcount FROM users,stats;
With Insert you do the same.
INSERT INTO users,stats (users.username,users.profiledescription,stats.postcount) VALUES ('$username','$description','postcount');
You could also do:
INSERT INTO users,stats (username,profiledescription,postcount) VALUES ('$username','$description','postcount');
You need to keep in mind that you can not have 2 same colum names in two tables, if you have 2 same column names you need to specify the table. 'table.username' or 'stats.username'. If you have only a "profiledescription" column inside the "users" table but NOT inside "stats" you do NOT need to type 'users.profiledescription'.
