Hi all,
My application uses 2 different databases.
so rollback condition here very complex.
example.
1. insert into tableA ---DB1 (points db1)
2. insert into tableA ---DB2 (points db2)
if second qury fails i want to rollback with respective databases.
How can i do that?

Are you using .NET? If so you can append a transation object to the command for each database and roll back or commit using them. But I think MS has some sort of DTC which I know nothing about.

Hi @all
I was looking around for a solution but i cant find anyone.
The point is, i want to make a list with the Tables inside of a specified mdb file.
Is there a way to read the table structure of an Access mdb?
Greetings

You could take a look at ADOMD, this is a library that can be used to create new access databases or change the structure of existing access databases.

If you are using .Net, the the GetOledbSchemaTable method of the database connection:
static DataTable GetSchemaTable(string connectionString)
{
using (OleDbConnection connection = new
OleDbConnection(connectionString))
{
connection.Open();
DataTable schemaTable = connection.GetOleDbSchemaTable(
OleDbSchemaGuid.Tables,
new object[] { null, null, null, "TABLE" });
return schemaTable;
}
}
If not, then see the ADOMD documentation, it provides a similar function.

Simple, check the documentation of the .NET framework for more samples

Hi Friends,
While I am trying to connect to the database server I am getting the following error.
ERROR: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I checked my web.config file. I didnt find any errors in this.
Please help me to solve this.
I am using VS 2005 and SQL Server 2000
Thank you

How are you connecting, SQL based Authentication? (I.e. username and password), if so then SQL by default does not have this enabled, you'll need to open up the MMC snap-in for SQL and enable it. If the SQL Admin doesn't know how to do this then... Google

Hi,
I'm trying to change the name of a column in an Access 2000 database (using C#). From my internet research, It looks like there is no sql RENAME for Access. I have come up with the code below, but please let me know if there is better sql code for this.
"ALTER TABLE Products ADD COLUMN NewColumn DECIMAL"
"UPDATE Products SET NewColumn = OldColumn"
thanks,
Ron

hi there i have this pro too.. i have a set of database in access format and i wish to change the name of my columns..how can i do it? do i need to change e codes written in visual studio?

Access SQL does not support renaming a columm with DDL See this for more info.[^]
The steps you mentioned are the only option using sql statements (you might want to add "Alter Table Products DROP COLUMN OldColumn;") after the Update statement.

I'm pretty sure you could do it using ADOX[^]

SQL Server 2005 Express is out now, it's a better choice than MSDE if you can make the choice. It has much better capabilities as well.

Will this be ok with ASP.net 2003? Also, which would be better MSDE or SQL server Management Studio Express since the express has EM?

Should be since it can act as a "standard" SQL Server, however you'll probably only leverage the new features using .NET 2
Skanless wrote: which would be better MSDE or SQL server Management Studio Express
All I know is that I tried installing MSDE once and gave up, installer experience was dreadful, tools were almost non-existant etc etc. SQL Server 2005 & SSME are great tools. They're only missing a few features from the full blown edition, apart from maybe some tools such as in-depth performance analysis and all the "boring" stuff that admins need concern themselves with I think that the only major difference between Express & Non-Express is the database size limitations. Express can only handle up to 3GB (I think).
I've been doing a big project for a local company and I started the database development on my laptop acting as the server since they hadn't received their copy of SQL yet, when it arrived and was installed the admin simply hooked my database files in and all I had to do was change the authentication and server names in my project and it ran happily (we'll that side of it anyway  ).
Basically in the short and long term I would have said SQL2005 is a better bet, much better environment than the one I came across with MSDE (even I could set up the database and permissions etc and I hate and have done very very little "large" database development).
