I have a SQL Server view that has three linked tables (one main table and two reference data lookup type tables) and have added "INSTEAD OF UPDATE" / "INSTEAD OF INSERT" triggers to it so that I can add/update the main table through the view.
This works well from T-SQL or through the enterprise manager application, but when I link to the view through Microsoft Access it is read only. Does anyone know how I can convince Microsoft Access that the view is, in fact, editable.

It turns out that you have to write a "Data Definition Query" in access to add a fake unique index on the view and execute this before the view will be considered editable by Access.

hi, can anybody advice me on good exception handling in TSQL? Thanks!
|
|
|
|
|
Which version?
In SQL Server 2005 you can use Try..Catch.. exception handling but in 2000 (or other RDBMS) you need to check the value of @@error after each statement and maybe use a GOTO to jump to an error handler in your proc code?

In sqlserver 2005 u can handle exceptions
using try catch block
but in sqlserver 2000
u have to rollback the transaction if any error occurs
That will be caught by @@error

I want to create a windows application which contains a datagridview control, and a ‘save’ button.
Once the form is loaded a table (Table1) will be populated into the datagridview automatically. Users can modify the data cell contents and then click the save button to update the MS access database file.
I setup the datasource and datamember of the datagridview porperty to be a simple MS Access datatable file db.mdb which only contains a table “Table1” with 2 fields, ‘ID’ (Text) and ‘value’(Number), 2 columns are displayed in the datagridview automatically.
Then I added a button_click event of the save button, and coding as below:
this.testTableTableAdapter.Connection.Open();
this.testTableTableAdapter.Update(this.dataSet.Table1);
this.testTableTableAdapter.Connection.Close();
Once the application is running, the values in Table1 are populated successfully into the datagridview, however after the user modified some of the values in the cells and then click ‘Save’, the MS Access database file is not updated.
I have checked that the dataset is updated as the user modifies the values, so the parameter of the Update method of the data adapter has no problem.
Could anyone give me a help, thanks.

Make sure your DataAdapter logic, including TableMappings, Fill, etc are all within a Try/Catch block, the you can print out the Exception.Message to see what is causing the I/O failure.
Good Luck

Hello,
I am getting DB_E_DATAFIELD_OVERFLOW error while using the Value property of Field object.
Sample Code.
Set rs = cmd.Execute(, , adCmdText)
Set Field = rs.Fields(0)
MsgBox Field.Name
MsgBox Field.Type //Returned Value = 19 i.e Unsigned Long
MsgBox Field.Precision // Returned Value = 10
MsgBox Field.Value // Run-time error DB_E_DATAFIELD_OVERFLOW
Details
1. Using SQL Server Database.
2. Data type of the Column is Numeric. (Length = 9 , Precision = 10)
3. Values those need to be stored in the column are in range (0 - 4294967296).
Important Detail about Provider:
a. Using our own Provider to connect to the database.
b. Provider is using the some APIs, abstracted from us, to fetch the data.
c. Data from those APIs are returned in the form of unsigned long.
d. RecordSet is generated and data is returned to the client.
Please Help
Thanks in Advance...

Just a guess, but don't you need a length of 10 in order to handle an unsigned long?

No, it is not required. It works fine.
At the first place itself data would not get entered if such was a case.

Database Restore Problem on MSDE.
I am using two database servers, SQL Server 2005 and MSDE in my application.
One module of this application provides database backup/restore tool using SQLDMO.dll.
In restore module I am killing currently connected users to that database before starting restore process.
It works fine with SQL Server 2005 but it fails on MSDE and it gives message "only user processes can be killed"
Then I tryied to kill connections using command KILL <spid> on MSDE but still it gives same error message.
Ex. If I am connected to test database using jc as user who has all the server role rights.
After this if I retrieve current spid's then it shows spid=7, user=jc, database=test etc.
When I try to kill this process then it fails on MSDE its giving message "only user processes can be killed"
Can anybody help me on this MSDE issue.
Thanks

This thread should be in the ASP.NET section...
As for your question: could you provide more information. Becouse I really don't see what is the point of doing this...
Q:What does the derived class in C# tell to it's parent?

I have a slight problem and wondering if someone else has encountered this.
Host platform: Windows 2000 Server, SP4
- MySQL Server 5.0.18 was running perfectly.
- Added MSSQL 2000 to 2K Server and now MySQL is getting a signal to exit.
It is desirable to run both on my server, and access either one as needed. I am thinking someone must have ran into this before and know of any compatibility issues.
Thanks for your help!

I am guessing here, but maybe you should check the ports they are using...
Make shure they use different ports...

Yes, check and make sure they are not the same. By default, MySQL is port 3306 and MSSQL 2000 is like 1433 (not 100% on this but close).

Yep, MySQL uses 3306, and MSSQL uses 1433 and 1434 I hear. I'll try reinstalling MySql at the expense of hosing MSSQL, lol Stay tuned.

Hi,
Im a newb to MS SQL so some help would be appreciated. I need to detect duplicated records in a DB by their email. Ive got the following code which works fine for displaying the email adress and the number of occurences -
sSQL = "SELECT *, COUNT(email) AS NumOccurrences FROM Contacts WHERE AccountHolderID = " & makeSQL(session("SAT_USERID")) & "GROUP BY email HAVING ( COUNT(email) > 1 )"
However i need to be able to display data associated with the email such as the username and firstname of each occurrance. So ultimately i need to display all records where the email adress of that record is also present in another record. Then display all the data associated with those records. I also need to group the matching emails together.
Im sure this must be possible, so your help would be rather good!
Thanks!!!!
