Select multiple blobs in one coloum one record

Good evening,
Ive been dealing with blobs over the past few days, and experienced several issues with my application dealing with them. I have solved it by splitting a blob file up over multiple records, so instead of having one massive blob in a record, I now have a table:-

CREATE TABLE `fileBlob` (
`fileID` BIGINT NOT NULL ,
`part` INT NOT NULL ,
`blob` TINYBLOB NOT NULL 
)

Select allOpen in new window

Which works great for uploading files into the table, but messy when downloading. Currently I call the statment and work through each row appending the blob output:-

SELECT * 
FROM `fileBlob` 
WHERE `fileID` =27
ORDER BY `part` ASC 

Select allOpen in new window

Is it possible to group all the blob data together ordered by `part` from a `fileID`, so something like:-

SELECT GROUP_CONCAT(`blob`) as blobData 
FROM fileblob
WHERE `fileID` =27

Select allOpen in new window

However the GROUP_CONCAT would obviously have to be ordered, and I dont know how to tell it to only dislay the blob data.

Any help would be appriciated.

Thank you
