Change the datatype of the ID field to one that holds values bigger than the one you have now.
|
|
|
|

Already my data type is big int.
My application is going to store voluminous transactions in the database.

Then use GUID in SQL Server. by using the function newid()
If U Get Errors U Will Learn
If U Don't Get Errors U Have Learnt

BigInt and you think you're going to run out of IDs??
You can't possibly tell me that your table is going to hold more than 9,223,372,036,854,775,807 (time 2 for negative numbers) records. I'd like to see the storage drive array that's going to hold this database, not to mention the backup scheme you've got.

Have you figured out why this is happening?

Hi,
In couple of procedures we are passing xml formatted data and inserting into temporary tables using sp_xml_preparedocument. Is there any other approach without using sp_xml_preparedocument procedure we can insert data from xml formatted data. We are looking for better performance. I hope somebody can help on this.
Thanks in advance.
Thanks & Regards,
Kumar

What is wrong with the stored procedure?

Might not be much else you can do. Maybe relook at how the xml data is being stored/fetched.

You need to write some code to take the raw data and convert it into an image format. There are numerous samples around that show how to do this, but without knowing which languages you are familiar with, I can't refine this down for you.

I'm generally familiar with SQL Server 2005 and I know there's an IMAGE data type that I can use to store pictures in the db. Can MySQL do the same? I'll be heading to the book store tomorrow to pick up a book and read up on this, but any experience in this area, particularly including taking pictures that are saved on my local disk and storing them in a web-based MySQL db would be greatly appreciated. I've seen sample apps for SQL Server 2005 that do this, but not MySQL and get the impression it's not nearly as easy, but probably possible.
Thanks!!

Yes. I think it is the blob datatype.

Thanks - I'll go get a book and see if I can find some examples.

I have a sample around here somewheres. I'll try to find it.

Thanks Paul. I also have the ability to use Access, and have samples for storing & retrieving files from that. Any advantage to MySQL, since I don't have MySQL, but do have Access? i.e., it'll cost me some money to use MySQL, where I can use Access for free, and this is a personal web site for storing photo's, etc.

Go ahead and use Access. Shouldn't be any problems. Since you are going to be storing photos, the best approach with a database is to save just the path on the server to the photos rather than putting the photos in the database.

That would certainly make it easier, but won't having a database and an "add picture and keywords" type of functionality make it easier to store, retrieve, and catalog? I have literally thousands and thousands of travel photos from all over the world, and want to be able to give friends and family the ability to search by subject, then return those that match the criteria, which would then show thumbnails, and a click would bring up the full size image....
Thanks for all the help!

You could still just store the path to the pictures even with searching abilities.

The logic and the simplicity of that just dawned on me - I still get "protected" storage from the site, and retain search and keyword capbilities. Plus I don't have the overhead of database load/unload and the associated database size issues.
Thanks Paul - that seems to be the most sensible approach and also easiest.

No problem. Glad it is working out for you

Hi all,
following is my yable schema
Tic_pk | Tic_Denom_No | Tic_start_no | Tic_end_no
--------------------------------------------------
100 | 5 |111112411| 111112510
101 | 5 |111112511 | 111112610
102 | 5 |111112611 | 111112710
all i want that when user selects a Tic_denom, a start num and an end number the middle record should also b considered
eg:
tic_denom_no=5
startno:111112411
end no: 111112710
the middle record should also be returned because the start and end of the middle rec also falls in the range..
pls help
thanks in adv
