If using Access 97-format, use Jet 3.51. Access 2000 and later use Jet 4.0.

Then this must be an access 2000 database. However it may be, the code works in an NT workstation. However in my windows 2000 box, it doesn't seem to work.
I keep getting:
The page cannot be displayed
There is a problem with the page you are trying to reach and it cannot be displayed.
Are there any special dll's that must be registered in order for ADO to properly work?
Anybody who's had any experience with getting ado recordsets to open against a conection with a state of 1 which indicates open. Please help.
Thanks.

Hey guys, first post ever.
I have a module which is event driven which is an adapter to a biometrics device. Essentially it only reads the database, never writes.
Because of this, when I have to enroll a new ID, I must check first that the ID has not previously been used. So basically the class holds a datatable of all users and their biometric key.
My GUI which utilises this component requests the class perform an enrollment, and then returns the biometric information plus any anciliaries to a business logic class and updates the database. Now the quirk is this.
SQL update command to enter the biometric data is run.
Then, the biometric class performs a "fill" from the tableadapter AFTER the data is updated.
This "fill" does NOT contain the biometric data sent in the update that was run previously.
Does this sound like a bug? The biometric class, and the business logic in the GUI share nothing more than the parameters for the SQLConnection, nothing else. If I close the GUI and then reinitialise the biometric class, it then recieves the updated biometric information.
SQL Server 2005 c#. I know the next question is to see code, but I'm afraid that is something I'm not able to do. Perhaps it will make it clear that if the user attempts an identification check and fails, this triggers the biometric class to run a "fill" on the data.
Thanks in advance guys, honestly any bone you can throw me will be worth it if it helps.

Weird!! thats really weird!
SInce you can't show the code, its really difficult to say anything for sure. but may be there is some problem with ur code when it refreshes the data in whatever control your using to display the data. Perhaps try emptying the datatable and then filling it again after an update opration and see what it does

Hi
I have to upload PDF files in database. I am uploading PDFs as stream and inserting into a column of varbinary(max) type. A column also to store file type.
So my database Table looks like
docs(PDFStream,filetype).
Here "PDFStream" is varbinary(max)
"filetype" is varchar(10)
I have the Full Text Index created on the table "docs".
my problem is when I execute the following
SELECT PDFStream
FROM Docs
WHERE FREETEXT (PDFStream, 'EQUIPMENT')
Does not fetch any result. But I have uploaded the PDF file with a line '........EQUIPMENT SALE AGREEMENT ......' ( dots here are just indicates other texts )
Any idea where I am going wrong ???
Any help will be appreciated.
Thanks,
Arindam D Tewary

I would guess that WHERE FREETEXT (PDFStream, 'EQUIPMENT') does not work because of the encoding maybe. Does WHERE FREETEXT (CAST(PDFStream as nvarchar(max)), 'EQUIPMENT') work.
//I have never used varbinary and freetext so this advice comes with no warranty.

Hi,
I am updating (not inserting) certain Excel sheet data to my SQL Server database. So I have Excel as source file & SQLServer 2000 as my destiination.
In the Transformation tab of "Transform Data Task" properties window I have written my customised logic to update excel sheet data to a particular table.
When I test my logic (by clicking the Test button of ActiveXScript window of "Transform Data Task"), the data gets updated without any error. But when I try executing this package, it gives me following error : "Cannot insert NULL value in column 'TestID', table 'TestTable'; column doesnot allow NULLS. Insert fails".
I really cant get hold of this weird DTS error as I am just updating a particular column of a particular table.
Additional Information:
1) 'TestID' column's Identity property has been set to No
2) There is no trigger written for that particular table
Kindly let me wat might be the reason behind this problem

Hi,
Further to my issue I found out that if I update 100 records from excel sheet to SQL DB table (by writing customise logic in ActiveXScript), after updating the proper fields it then inserts that 100 records in to that table.
Why does that try to insert again all the 100 records of my excel sheet to the SQL table?

SELECT * FROM <TABLENAME> WHERE USER = 'JOHN' AND PASS = 'MYPASS'

I cant see what the problem is, because after the select statement you will have all data specific to that user, so redirecting the user to the correct page should be a breeze. Just pass the information of the user to the next page. Unless I'm totlally mis-understanding you.

HE DID!!
He gave you this:
SELECT * FROM <TABLENAME> WHERE USER = 'JOHN' AND PASS = 'MYPASS'
But since you've told us nothing about your database structure it may not be correct.
If you want more help you'll have to help us understand your problem. Repeating the same statements over and over again do not help. You need to give us more information.

What other answer could you expect from that?!

You mentioned nothing about login pages or redirecting users. How were we supposed to know, especially since you posted this in the "SQL" forum?
If you've got the data and youre question is about ASP.NET post in the appropriate forum.

SELECT * FROM <tablename> WHERE USER = 'JOHN' AND PASS = 'MYPASS'
this is the write query...
now if u r using c# or vb.net
get result of this query in datareader and dataadaptor..
if any row returns that means username and password is correct... then redirect to the other page..

They Already gave u the right Query..if u're try to implement that query in your
apps just change the where value, ex :
<br />
Select * From [my_table] WHERE username = '" +UserText.Text+ "' AND password = '" +PasswdText.Text+ "'<br />
wat else do u need they gave u the right query u need

Hi all,
I would like to know whether one uses the to_date function in a update statement aswell, as one would in a insert statement (when making use of a Oracle Database).
Many Thanks

I make use of the 'to_date' function everywhere. Whether it's a 'select', 'insert', 'update' or even a 'delete' statement, you can use a function call just about anywhere.
Do you have a specific instance that is giving you an error or problem?

Hello guys..
Looks like I just need a litle help on my SQL syntax in C#.NET
I have a field in my database which is DateTime type. Looks like I can't get the syntax right for comparing the value from the textBox with the field in database.
Now what I have looks like:
<br />
DateTime ShDate = DateTime.Parse(txtDate.Text);<br />
cmd1.CommandText = "SELECT ShipedDate FROM Details WHERE Details.ShipedDate = #ShDate#";<br />
When I fill dataset with the adapter which has this SelectCommand it will report error in date in the syntax expresion. Now the variable ShDate has a DateTime type in C# and it stores a date from the textbox with a help of conversion and it is in a correct format(I cheked while debuging).
I think the problem is somewhere here = #ShDate#. I bet I am missing some quotation marks ("") or single quote('').
So does any one have a clue?
Thanks..

Hi,
I think you are just now migrating from MS-Acccess.
When comparing date in SQL Server no need of "#".
Just simply " = ShDate " is enough.

Can you try this out...
DateTime ShDate = DateTime.Parse(txtDate.Text);
cmd1.CommandText = 'SELECT ShipedDate FROM Details WHERE Details.ShipedDate =%' + ShDate + '%';
See if it helps.
Thanks!

Apologies, ignore my previous post..
Try this
DateTime ShDate = DateTime.Parse(txtDate.Text);
cmd1.CommandText = 'SELECT ShipedDate FROM Details WHERE Details.ShipedDate like' + '''' + '%' + ShDate + '%' + '''';
I tried it on my sql box and it worked.
Hope this helps
Thanks!

I'm looking to develop an application that will require a small database table structure (not more then 4-5 tables). I wanted to make the database internal to the application so that there wouldn't have to be a link out to a web server/SQL server anywhere, but with just receiving a new datafile to replace the old one, it would be able to pick it up. Is there any code/project type in Visual Studio that would allow me to create such a database that could be deployed with the application and be able to be queried with a SQL/Oracle type interface/query? I am open to writing the application in either Visual Basic or Visual C++.
