what is more efficient, opening the database once in the beginning of the page then closing it at the end of the page, or opening the db connection each time you need it.
for example:
i have a page that executes 50 queries. is it better to open the db, execute the queries, then close it, or to open and close the db 50 times?
Which of the following would be the most preferred connection string method? What is the difference?
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("/marketing/ics.mdb")
strConn = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("/marketing/ics.mdb")
I 've coded an asp webpage where a user could toggle a boolean value through a checkbox.
When the checkbox was pressed, the page posted the toggle action to itself, a
connection.execute "UPDATE tableName SET fieldName=(Not fieldname) WHERE field_id=1
query was performed and the checkbox, after I had retrieved its new value through a recordset, changed its appearence(state). At first I used an MS Access DB and it worked fine.
After I had switched the hole application to work with MS-SQL, although I changed the above query to Code:
Wondered if anyone could help me out with some simple connection string problems I'm having.
Ive got this on the page so far and it works:
----------------------------------------------
Dim strConnString
set strConnString = server.createobject("adodb.connection")
strConnString.ConnectionString="DRIVER={Microsoft Access Driver (*.mdb)};" & "DBQ=c:Inetpubwwwrootdlnforumforumadminwwforum.mdb"
strConnString.open
-----------------------------------------------
But I want to change it to a Server.MapPath method, so I tried the following:
------------------------------------------------
Dim strConnString
set strConnString = server.createobject("adodb.connection")
strConnString.ConnectionString="DRIVER={Microsoft Access Driver (*.mdb)};" & Server.MapPath("forum/admin/wwforum.mdb")
strConnString.open
---------------------------------------------------
But now I get the following error:
-------------------------------------------
Error Type:

Operation was canceled.
Can anyone help me out?
[This question is directed at Bob Barrows, but perhaps someone else knows an
answer. In any case it is good information for the group.]
I really like Bob's "stored procedure as method of Connection Object"
technique. It is convenient, compact, and concise, and simplifies protection
from SQL injection.
HOWEVER, I cannot figure out a way to pass a null value to an INT parameter
when I use this. Null string parameters are fine. The error reads:
Microsoft OLE DB Provider for SQL Server error '80040e07'
Operand type clash: text is incompatible with int
As you can imagine, "text is incompatible with int" gets my attention. I am
explicitly passing a null (not the string "null"). I am using JScript on the
web server and connecting to SQL Server 2000. An example: Code:
I work with ASP for several weeks now and i really like it! But until now i have just used it in connection with my localhost. I made connections to a SQL Database and to an ACESS Database with using the ODBC Tool from WIndows!!
Now i want to publish my website but i don't know how to handle the connection string kind of thing. My MySQL-Database is on a different server than the website and i need a connection string where i can type in the server, a password and a username and it should then connect.
I am familiar with connecting asp pages to sql server when both servers are
on a LAN.
Can anyone advise on how to connect when the servers are remote from each
other?
I was wondering if i can create an if/else statement that checks if my connection string that opens a database ie:
cnnDB.Open Application.Contents.Item("CONNECTION_STRING" )
(the actuall connection string is in my global.asa file incase u were wondering) ...or if the database can't be found or opened, will run some other code... like a message?
hope u get what i mean.
this is just incase a user has the DB opened, or is in the process of overiting the DB or something, the page would not display that Microsoft JET Database Engineerror but display a message i set up in the if/else statement.

View Replies View RelatedI have been trying to get an intranet search page to work that looks at an Access database. The database is called database.mdb, and lives in the root of the site, as does the .asp (security is not a problem at the moment). The code was taken from an asp website.

I manage my department information through an Access relational database and an http network model database. Naturally enough I want to combine them.
We have an old NT driven LAN with pc's running Win 9x or XP pro. The file server is nearly up to capacity on storage and bandwidth, the new XP machines have plenty. The network is backed up daily. If possible I want to use the XP m/c as a web server.
I want to use IIS and ASP from an XP m/c to read and write to databases on the file server but can't seem to get the connection string right, I have tried many, with and without DSN's. Having checked up on IIS (installed on XP pro) I suspect that it can only connect locally. Certainly everything runs on a test setup in C:/inetpub/wwwroot which can be accessed across the LAN and ASP runs fine.
i want to open a connection for password protected database but i don't want to write password in code as it can be seen by my host provider and misused is there any way I can read database password without writing it in my code.

cN.Open "DRIVER={Microsoft Access Driver (*.mdb)}; password=joy; DBQ=" & Server.MapPath("db1.mdb")
above example works fine but i dont want to write password in my code is there any way i can do it.

I have one database, but nine web sites all linking to this database for client input.hen I use the domain web site that the database is atored under, the ASP page updates the database as required. I have been using the following connection:

Now I have saved this ASP page under one of my other domain names and have tried using an ODBC connection as follows:
"DSN=ODBC Connection;Driver={Microsoft Access Driver (*.mdb)};Dbq=my web site database domaindbmy database.mdb;Uid=Admin;Pwd=;"
Unfortunately when I complete the ASP page on this web site, and submit, the database is not being updated with the records.
