I want to insert jpeg file in SQL. How to do this?
You probably want to use the binary, varbinary or varbinary(max) data type.
Of course, you have to convert the (JPEG) image to a byte array first in order to store it in the database. Depending on the programming language of your choice this can be easy or hard.
Not sure if you can read files from a T-SQL command and store/retrieve them from a database. Then again, I don't think you would want such a scenario in real-life.

love the data and how sorted and process, and how can controlled.
I wanna to know if can build own server, and how can upload the data in it.
That depends on the type of data that you want to store.
Assuming you simply want to upload and store files on a server, then you can consider using minio. You can run it locally by following the instructions described here.

Please let me know how to insert images and videos to table using SQLDeveloper.
You don't.
You can insert images or videos into an Oracle Database. You'll need a database, and a table, and at least one column setup to store your media. One way to do this is with Oracle Secure Files and the Binary Large Object Types (BLOB)
Once they're in the table, you can retrieve and update them in the client tools and applications, including SQL Developer.

How do you store big objects using NSUserDefaults efficiently? Any help will be appreciated. Thanks!
I would avoid using NSUserDefaults for anything large that you want to store. You are better off either writing the data to a file or storing it in a db such as core data. Depending on what you are trying to store one of these can make more sense then the other.

You can look at NSKeyedArchiver or NSFileManager plus whatever type of data you are working with for more information about how to write it to a file.

I'm looking to create a program that will sift and sort through tabular data created in excel format. I would like to be able to iterate through several .csv files within a folder, and create dictionaries of information that can be used to generate metrics and reports. I've been developing for a couple of years now, and I've never had to use xcode for anything like this.
I am curious if this is an easy solution to manipulating data or is there a preferred way of dealing with data in this form?
You can use CHCSVParser to read and parse the .csv files.

I know that the best way of accomplishing similar tasks is to save intermediate results into a file and restore the state from that file. But out of curiosity, I just wonder whether there is a way to save a process and retrieve it after a reboot. That's all.
Problem solved. I create a dump file of my process and get the address of my variables. Then I extract all the data I need from the file.
