Comparing Two Ms Access Backend Databases Of A Web Application?
Dec 22, 2010
at our office we take daily backup of ASP.net application ms access backend for the next few days we need to evaluate the changes made to records in the database tables at the end of each day i want to compare 2 access databases first database is the backup of yesterday and second database is the backup of today i thought of the following algorithm, how to proceed to compare the datatables / gridviews
i need to display th rows / cells containing the differences / updates / deleted data
I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.
i am new to asp.net programming i am trying to connect asp.net web application with ms access 2007 database. i have taken with two text boxes and when i enter some data in it and press submit button the data must load in access db i created with same fields.
my code is :
Syntax error in string in query expression what is the correct way of inserting data into access db and what is the Syntax error in string in query expression.
I am trying to make connection to a remote database server and I am getting the following message. I think i have to grant access to the client maching from my database server.. How do i grant access to an ip addess?
ERROR [HY000] [MySQL][ODBC 5.1 Driver]Access denied for user 'thelp'@'220.127.116.11' (using password: YES) ERROR [HY000] [MySQL][ODBC 5.1 Driver]Access denied for user 'thelp'@'18.104.22.168'(using password: YES)
I created a new database with the help of Database Configuration Assistant !I created with the scott account.Now i'm not able to connect to the database with the connect identifier with the scott account.The error i get is.,

I'm learning to use webmatrix via the tutorials on the website. I've had success with all table operations, when only using one table. I'm using the following address to access the site uredi_let_padalce.cshtml?LetId=4 and the is code:
The page works if I write: where LetId=4 instead of @0. But if I leave the variable I get the following error: The column name cannot be resolved to a table. Specify the table to which the column belongs. [ Name of ambiguous column = LetId ] If I specify the table name LetId_PadalecId. LetId=@0, then I get the parameter missing error. How could I tell the server which LetId I want?
We have an ASP.NET 3.5 Web application in which we have faced the below issue:
The application is working fine but suddently at one point application URL prompts for the authentication. When we (the support team) checked the server, we were able to identify that the access was denied for some of the main files (like web.config, default page). When we enabled the access the application started working fine.
Below is our error message. This happens around 5 - 7AM daily, and we are struggling with identifying the root cause. It's hard for me to believe it's code related, but anything's possible. Still, what's odd is the app runs fine for a day then an IIS reset is done and everything is fixed. Is there any way this could be related to code and has anyone dealt with this error before? Could a job or some permission being run behind the scenes be using this same dll and cause it to be overwritten?

I am developing a web application with back end as Oracle. I call the procedures from web application when ever some update, create or delete for the records needs to be performed. How to maintain the connection in these scenarios.
Can I open the connection and maintain it through out the application till user logs out?
I could do backup and restore mysql database at my web application run time with VWD 2008 Express. But I test these with IIS, any web browser's progress bar is not increased. My code is the same with this link - URL] . Here, Some facts that makes it not process - I think
My database admin has no password. At run time with VWD, Command Prompt appears and ask to enter password. With IIS, this not appear.I run VWD as a admin. So is there any security with IIS?Finally, we will use this web application with Remote or Virtual Server. Now we could access this application from Remote Server via any web browser. So I test this backup portion but it not work. Here, I give the file path - D:DB - that is valid in my client or current pc but IOException generate message 'Device is not ready.' Drive D is not in Remote Server. So I change Drive E: that is valid in Remote Server. This time, Run time error appears and Description is "An application error occurs on the server...". I think that any client can save backup file under his current pc.
My Application uses two SQL databses, one for membership/roles (ASPNETDB.MDF) the other for my data. When deploying to a server do I have to use two connection strings, one for each database? I am using the publish to provider wizard with VWD 2008 to replicate the databases on Sqlserver 2008 (Windows server 2008 R2). I have my data connection working fine, I am just trying to get mebership and roles working.
i want to search for data in informix using a like('%Name1%') from my .NET application. The query that i have written is something like this:
select * from tableName where columnName Like CONCAT('%',CONCAT('Name1','%')) ...... this query when run from the front end does not yeild the desired result set ......however when i execute it from the db level i get the correct result .... also an intersting thin that i noted is ...if i do a LIKE('%' || 'Name1' || '%') from the front end i get a syntax error ...however this works just fine when i execute the query from the db...... ive spent over 10 hrs trying to figure this out ......but have not found a solution for it on my own ...... also, the following works perfectly :select * from tableName where columnName LIKE CONCAT('%','Name1') .....from the application... likewise select * from table name where columnName like CONCAT(Name1,'%') works ...........* the vale fields need to be replaced with a '?' in the front end ...informix automatically replaces it when executing the command statement....so the commantext for all informix commands look something like this : select ColumnName from tableName where columnName1 LIKE CONCAT('%',CONCAT(?,'%')) parameter is 'Name1'
