Table structure from database.

Hi,

Is it possible to retrieve in C# the table structure (primary key, type of data, ...) ?

Thanks a lot.

Sébfrom what database?
from sql server 2000 for example ...
From sql server sir :)
I am not sure that my suggests will solve your problems,
I think that you should write a Sql statement as follow:

ALTER DATABASE database
{ ADD FILE < filespec > [ ,...n ] [ TO FILEGROUP filegroup_name ]
| ADD LOG FILE < filespec > [ ,...n ]
| REMOVE FILE logical_file_name
| ADD FILEGROUP filegroup_name
| REMOVE FILEGROUP filegroup_name
| MODIFY FILE < filespec >
| MODIFY NAME = new_dbname
| MODIFY FILEGROUP filegroup_name {filegroup_property | NAME = new_filegroup_name }
| SET < optionspec > [ ,...n ] [ WITH < termination > ]
| COLLATE < collation_name >
}

SqlClient.ExcuteNonQuery(......);
SQL server 2000 why ?

Thanks

I'm interested in the structure of Access and SQL databases

TableAdapter Insert (Primary Key)

Hi

I have just started to learn ASP.Net. However I have some experience with ASP.

Anyway I have created a asp-form which should create a new entry in the database after you have clicked the submit button.

I created a tableadapter and following simple code:
tbUsersTableAdapter topAdapter=new tbUsersTableAdapter();
topAdapter.InsertUser(DateTime.Now, DateTime.Now, DateTime.Now,true,false, txtNickname.Text, 2, txtEMail.Text, txtPassword.Text,"");

Here is the SQl Command without the primary key:
INSERTINTO[tbUsers] ([CDate], [MDate], [ADate], [Active], [Activated],[Nickname], [Role],, [Password],[IP])VALUES (@dotnet.itags.org.CDate, @dotnet.itags.org.MDate, @dotnet.itags.org.ADate, @dotnet.itags.org.Active, @dotnet.itags.org.Activated, @dotnet.itags.org.Nickname, @dotnet.itags.org.Role, @dotnet.itags.org.eMail, @dotnet.itags.org.Password, @dotnet.itags.org.IP)

This works fine as long as I put the ID (Primary Key) into the Insert command. But I don't know how I can find out the next avaiable primary key. I have thought it would be automatically incremented. Anyway I went to the properties of the tableadapter and there was a property which I switched on for my primary key field "AutoIncrement". However it still doesn't work.
Before I used to work with MS Access and OleDB Connection. There I just skipped the Primary Key Value and it has been created automatically. Here I get an error message that the primary key can't be null.

I hope somebody could help me with that or has an idea what I'm doing wrong.

thx

Hi

I searched and tried out a lot of things. Finally I found the problem today. I had to open the table with the Server Explorer. Actually I set my ID field to Primary Key but I forgot to set the Identity Column. After I set the Identity Column to my ID field it worked... great;-)))) Now I can just add a new record with skipping the Primary Key and it will be generated automatically.

thx all
