How to store the images in db2 as BLOB ?????

Hi,

May I know how to store and retrieve the images in the database as BLOB data type unless using extender?
Can we store like that unless using extender?



Thanks,

Hi guyprzytula,

I have been read the article BLOB for Java.But what I would like to know is that whether we can insert and select the BLOB data types or not and if can,how to do that?
I am not using Java or Unix.
I am working on the window environment.


Thanks,

blob

as indicated before, the only way without a program is using import and keeping the blobs in a file
with import replace the column contents with the location/name of the blob file
do import with : modified by lobsinfile
retrieve is not possible : blob is not displayable
select with extenders or application
see develop.works for some articles on how to handle blob data from within an appl

Dear guyprzytula,

If I store like c:\data\picture1.jpg,how the database store(as path or as image? I mean the database will store the path as "c:\data\picture1.jpg" or will store the actual image?
After I store the image as "c:\data\picture1.jpg",can I delete the physical picture(picture1.jpg)? I mean ,if there is no such path(c:\data\picture1.jpg) in the PC,can I retrieve the image?

Thanks in advance,

yes the entire file will be stored. If needed, the physical file can be removed.

Thank you so much,guyprzytula.
Btw,if I store the image in the database,the database size would be about 2 times bigger than before.Am I right?

May I know what is the advantages and disadvatages of storing the CLOB,BLOB data in the database?

Thank in advance,
