Hello,
A table contains image type data. Actually it is text file. I don't know how to convert it to text and display. The image data size is about 20kb. Please advise.

Thanks.
Harry

SELECT CAST(imageColumn as varchar(max)) FROM myTable

You probably can't display all 20K in Management Studio's query results window, but otherwise that will work.

I thought you needed to go through varbinary first... but who knows...

Select cast(cast(imageColumn as varbinary(max)) as varchar(max)) From myTable

Ugh, you're right.

Kids, this is what happens when you don't test your code.

if you wanna convert the image to text file, you have to use a image conveting program, for this, according to my experience, you can search in google or bing and you can get many FREE online image converting solution, this is what im using, hope it can solve your problem.
