You can use C# as a macro language in Excel?

Perhaps the Sync Framework[^]? I'm not sure on the performance though.

Could someone pont me in the right direction here cos I am pulling my hair out and I have little to start with lol
I am working with 3 tables
User Table:
Auto_ID
User_Name
Profile Table:
Auto_ID
User_ID (This is taken from the Auto_ID in the User Table e.g. 20)
Prof_Img
Comments Table:
Auto_ID
Message_To (This is taken from the Auto_ID in the User Table e.g. 41)
Message_From (This is taken from the Auto_ID in the User Table e.g. 20)
Message
I need to be able to display the Prof_Img for who the message was _to and _from I just can't figure how to get the individual picture references from the same table in the same query. I can get one of the pictures but not both, am probably not thinking about it correctly, well obviously I am or it would work lol
Oh and I need the User_Name to go with each relevant picture
If someone could give me a little guidance please it would save my hair line lol
Many thanks in advance
Regards
Ray

OK, you need two joins to the same tables (once for from, once for to; and both once for name, once for image); this will only work when you use aliases to discriminate the identical tables.
This will not be correct, but indicates the technique; try something like this:
SELECT FU.Name, TU.Name FROM Comments
JOIN User as FU ON Comments.Message_From=FU.Auto_ID
JOIN User as TU ON Comments.Message_To=TU.Auto_ID
WHERE Comments.Auto_ID=MessageID
which, once correct, you can extend to also handle the images.

Hi All,
I have a table with 50000000+ rows in SQL Server 2008 R2 Express. I am querying this database table from a .NET application. Unfortunately this table is not having any PK and probably its now possible to implement one.
When I fire my query it doesn't works due to Timeout. I get error:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I am reading this with execute dataset method to fill my Datagridview.
Please suggest me approach I should take to make this work.
thanks

Increase CommandTimeout period to avoid this error

However I would suggest whenever you are pooling such a huge data in one dataset, if possible, try to fetch data in small chunks.

millions of rows in a DataGridView? I pity the users then.
This forum holds some 50,000 messages, yet you see only a few (say 25) of them at once.

Sounds to me like you are trying to fetch way too many rows in one shot. You should re-think your logic and select only the rows you really need in your applicaiton.
If you really need to accessing millions of rows, then maybe you should be using a datareader and not try to fill a dataset.
Why don't you post a brief summary of what you are trying to do any the folks here will give you all kinds of ideas on how to attack the problem.
Good luck.

you're talking to the wrong person here.

Yep.
I replied to the wrong thread. My previous comment should have been applied to the original author, "logicon".
Sorry Luc.

Hi David,
You are correct, I should use datareader.
The requirement is to provide a tool which brings rows in Excel from SQL Server so that end user can play with it using pivot and other excel stuff. What I initially planned was to write Excel Add-in. Unfortunately due to version issue (I had Excel 2007 and end user is having Excel 2010) I decided to write Windows Form Application which will have a DataGridView and "Export To Excel" button.
Internally, SqlDataAdapter 's Fill is used here in my current code.
I will try the DataReader and share the result with all you
Thanks Everyone.

Use a DataReader to write a CSV file -- the user can then open the CSV in Excel. Slick as snot.
|
|
|
|
|
Use SQL server to output the resultset to a CSV file on a shared folder - slicker than snot!
Never underestimate the power of human stupidity

It's horrible to load at a time, use paging technique in query. An example SQL Server 2005 Paging Results[^]

You need to change your requirements.
And what is the growth rate of this table? What happens when it is 10 times bigger than it is now?
