Interesting question Steve. I had no idea about this, except the connection of VARBINARY and FILESTREAM. Luckily was able to guess the correct answer 🙂

I don't have idea about filestream but i'm sure other than IDENTITY property no other attributes will be copied to new table. So i guessed it should be varchar(max) but it was wrong , could have gone through the BOL before answering.

I am not surprised that SELECT ... INTO loses the FILESTREAM attribute. However, I was surprised to find that varchar(max) with FILESTREAM would be converted to varbinary(max).

So then I did a bit more research, and found that FILESTREAM is not even permitted with varchar(max) - so not really a surprise that all FILESTREAM columns get converted to varbinary(max), since that already was their data type! :hehe:

But why did you think the source type was varchar(max) filestream? varchar(max) isn't a BLOB type any more that text was it's LOB but not BLOB, so varchar(max) filestream doesn't exist.

Very Interesting, Steve. Thank you for posting.

I have read about filestream but never tried it practically. For testing this code, which came with good amount of learning and couple of hours of BOL exploring , finally I was able to create the tables with the FILESTREAM attribute which only can be achieved by script creation and not using with GUI for table design. Also I didn't know this needs a default filestream filegroup and then one file with the filestream type needs to be created before creating any columns with the filestream attribute. 🙂
