Is is possible to setup the format of a column so that in a select it has a certain format? For example in Oracle I could do something like:
column columnname format a18
column columnname truncated This would format columnname so that it was only 18 characters wide and would trucate any extra characters. Is there anything like this for SQL Server (I'm using MSDE). Thanks.

select cast(test_column as char(15)) from test_table
This will truncate the column to 15 characters if it exceeds it, or pad on the right if the column doesn't
select cast(test_column as char(15)) from test_table
test_column
---------------
1234567890
12345
(2 row(s) affected)
select cast(test_column as char(5)) from test_table
test_column
-----------
12345
12345
(2 row(s) affected)
The test_table had two rows, test_column was "1234567890" on the first row and "12345" on the second.
There is also a convert function you may like to look up which gives finer control of the output format (especially for dates) if you need it.
Does this help?

That helps quite a bit. Thanks very much for the information. The only thing is that with that format you have to do it in every select statement. Is there anyway to make it more global (at least for a session) so that whenever a specific column is involved it gets the format that you give it? If not I can definately use the cast function. Thanks again for the help.

I've written a fairly simple C# application that reads an MSDE database. The project is to distribute this application and database on CD.
The client would install the application and the database would reamain on cd.
My application works fine, the problem is developing a solid set up routine for deploying the application and MSDE.
A toolkit and a dozen articles exist on the MS site but not one executable example.
Does anyone have a small example of a 'setup' application to install an application, MSDE and it's database.
Thank you,

I've tried to install the add-in and get a 'failed to load ... unknown error 80131500.
I uninstalled Studio.NET and tried it again and still got the same error.
What next.

OK, in the 2003 VS.NET...
When did the error message apprear?? During the installation of the plugin??
I had no issues in my case. If you have any installation problems for the plugin, you try to re-install the same after rebooting the PC

I get the error when I start a new 'startup project' and then select the add-in through the add-in manager.
I've reinstalled everything with the same results.

I ran the setup for the toolkit
I put a copy of the dotnetfx.exe in the C:\Program Files\Microsoft\MSDE 2000 Deployment Toolkit\Template\CD directory.
I started a new setup project.
I selected Tools^Add-in Manager then checked the MSDE 2000 Bootstrap Loader Configurator.
That's when I get a dialog that indicates that the add-in failed to load with and unknown error 80131500 and offers to remove the add-in.

I contacted the reference in the documentation and found out that although the dates on the package was the same as the one I downloaded ... One of the .dlls (M2KBSLC.dll)had changed.
I redownloaded the toolkit (for about the 5th time) and did a reinstall.
In the end it worked.
Thanks for your help!

My problem has 2 workflows:
WF1:=>I'm OK<=With an active connection, the user can drag and drop fields in a table and I'm succesfully generate an SQL string.
WF2:=>I'm now in trouble<= I let the user type the SQL string in a richtextbox. And now I must display all the tables, the relation ships, the fields etc... specified in the SQL string typed by the user. Would you please give me some helps? I really need an effective algorithm to parse this SQL string. Thank you in advance

I have written a basic SQL parser before, but it was parsing generated SQL, which was fairly tightly under my control anyway. I would not want to do it for SQL that the user typed! SQL can be very complex, with nested queries and multiple ways of writing the same query. Most typed queries will be simple though, so maybe you can get by with something basic, that works in 90% of cases.
Alternate solution 1: I would leverage what I could from SQL Server. In SQL Query Analyzer, you can look at the query plan for a particular query. This shows some of what you are interested in. Perhaps you could find out how that is done, and use a similar technique.
Alternate solution 2: SQL Enterprise and SQL Query analyzer both have a query designer tool that does something similar to what you want. It may be that there is an underlying API that you could utilize.
Alternate solution 3: Create a temporary view from the SQL, and then use various techniques to analyze that view. sp_depends will tell you the tables, sp_help will tell you the result structure. Not sure how you would tell the relationships though.

Would you please tell me more about the Solution 2? It will be better if I can utilize some API, but which API? Can you show me an example using these API? And would you mind send me your project that you've written? Thank you.

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Please advice. Thanks a bunch.

You can use WITH ( ROWLOCK ) after the table name in the FROM clause. However, you should consider whether you should be holding your transactions open for user interaction. It's usually better to select the results and release the locks, then perform comparisons to determine if the row has changed when the user wants to update. It's up to you what you do if another user has changed a row since this user started editing.
Stability. What an interesting concept. -- Chris Maunder

I would recommend not using locks. What I do is use a time stamp column. During the update stored procedure, I do a check to make sure the date time stamp is equal to the actual value in the table for that record. If the time is the same, I update the column to the current date time prior to the actual update. If not, I raise an error, then requery the table information for the last change user and date time.
Again, I would not recommend do any type of locks.
Just my 2¢,
Michael

This might help someone else out; in any event, I wanted to get this off my chest.
Some s/w I've worked many, many hours on uses the ATL OLEDB classes to communicate with a database, which is specified by a connection string. When we use the SQLOLEDB provider against MSSQLServer, we have no problems (well, not with the database!). However, using OraOLEDB.ORACLE against Oracle 9.2 gives some really bizarre behaviour.
Normally, if you want an updateable rowset, you just specify (DBPROP_IRowsetChange, true) and (DBPROP_UPDATEABILITY, flags).
Open your rowset, call SetData() to update, and all goes well.
However, with Oracle, if your rowset contains blobs (long data), then you also need to specify (DBPROP_IRowsetUpdate,true), which *should* give you a deferred update rowset, meaning that you need to call SetData() and Update() to update the row. Now (a) you don't need to call Update(), just SetData works! and (b) this doesn't work for SQL Server
All in all, a sorry little mess.
Thankfully, it's possible to determine from a CSession object whether we're connecting to an ORACLE database or not, and thanks to the ability produce a template, the rowset property setup and updating of the data can also be hidden from the 'casual developer'. But  isn't OLE DB intended to take care of this crud for us? Come back ODBC, all is forgiven....

Ahhhhhh....Many Oracle problems you still have grasshopper....
Ah well - 30th not long to go....still nothing in pipeline?
