You may not see this, but this video has helped me tremendously. Aggregate functions drove me crazy until I watched this video. Now I have a better foundation and feel a lot more confident with this topic now.✊🏽🔥🔥

i don't know if you've answered this in any of your videos but are you actually going to be SELECT * on a massive database? is there a query that can show you how many rows / columns you have so you don't crash your system? or can you do a query that shows column names and how many rows?
@stri062 жыл бұрын
I know this is late but for anyone with the same question IRL you never do that , to find out how many rows are in the table COUNT(*) can be used and if a preview of the data is needed LIMIT can help with that i usually use LIMIT 5 or LIMIT 10 For field / columns DESCRIBE table_name can show the colums and data type

I'm trying to do this problem: Which student from Georgia has the highest GPA? I do SELECT MAX (GPA) From Students WHERE State='GA' and I only get the GPA without names. how can I specify the student Name? please help
@chopramo4 жыл бұрын
SELECT MAX (GPA) , StudentName (Whatever column name identifies with students) From Students WHERE State='GA'
@erickcanals25534 жыл бұрын
I think this would work too: SELECT StudentName, GPA FROM Students WHERE State='GA' ORDER BY GPA DESC LIMIT 1;
