Great explanation, but what about stored procedure using OUT parameter??
Having issue with code in which for some reason. I successfully made 2 stored procedures in a database however the one I did for a parameter that's supposed to be for when finding a particular date within the table when I call the stored procedure it's returns empty set. Yet when I call an asp for all records it'll do so successfully
HI, Tell me what if I want to provide Customerid 1 and 2 at one time means 1,2 then what will be my sp?
Can you please do a video on cursor
Can we use date function as parameter
ill stick with the dollar signs because i think that's cooler. 😂
Can this be used on microsoft sql server?

Procedure is just an action that executes your statements Views are virtual tables (your rensponses), unlike normal tables that hold data and are stored in Databases, views create tables with data filled dynamically on the fly. You use those if you dont really need store specific tables, but said tables can help ya with solving some problem / calculation.

Why varchar is "WarCHAR" and not "WarKar" when character is "Karactor"
those using ssms CALL is EXEC
Don't you have to use a database first?

He did create a database. Otherwise he wouldn't be able to extract data. He did so in previous videos of this series.
Can you please do a course on developing a web application with nodeJS, there isn't any good tutorials on youtube for that and I think you would be great at breaking it down.
