Hello. I have a table with 3 columns:
Name Char(50)
Location Char(50)
Image(text)

How can I save an image in a text datatype? how's the conversion will be? Thanks for your help in advance. Using C#, SQL-Server, Windows Form Application

What I have tried:

It's my first time to hear that images can be saved in a text data type so I have no idea what to try yet. Sorry.

I've already seen those links and as I said into my question "How can I can save and retrieve image to SQL server database's text(data type) column." Those links will show you how to save it in an IMAGE FIELD(IMAGE DATATYPE). What I'm having trouble is how can I save an image/picture in a TEXT FIELD(TEXT DATA TYPE IN THE DB). Think there's going to be a conversion of image/pic to text or what...

Don't store images in text columns, you have to convert the image to something like Base64 to avoid problems - and that gets very inefficient as far as space is concerned.
Instead use a VARBINARY column, and insert the bytes from the image directly via a parameterised query.
This shows the code to do it: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^]

Ohhh I see. Thank you very much, but the company asks me to do is save it into a text column just like how they do it in FoxPro... I am a newly hired and database is created by them so I cannot just alter the table's text column and changed it to varbinary xD

If you want it in a text field, you will need to convert it to Base64 or similar, as I said.

But ... it's a piss-poor design decision, particularly if the images get large. It wastes space in the DB, it increases bandwidth usage, it means more processing needed to store and retrieve it, ... generally not a good idea, even if it historically may have been done for good reasons in a very old application.
