Wondering about best practices as regarding database connections and usage (MS SQL). Was building a class to contain all of the methods and suddenly wondered if this was the best way? Using a sledgehammer to crack a walnut etc.... Code:
View RepliesI'm about to start building a website which has a MS SQL back-end database. The host annoyingly won't allow me to connect to the database through Enterprise Manager, so he's advised that the database be created entirely though scripts.
I'm not particuarly good with T-SQL, so is there a tool I can use to generate the scripts from a database I have built? Can Enterprise Manager output the source code to build a database once it has been built? Could I set up and test the database on a different MS SQL server, then export the entire script and contents into a SQL query which could then be run through an ASP script to build the same database on a different server?
I have a database class that I've been starting to use with my ASP apps and I was wondering about having too many database connections on one page. I'm beginning to write other classes that use the database class to reach into a table and pull data out.
Say for instance I have these classes:
Database
Users
News
Reviews
All of these classes have a method like getUserByID() or getNewsByID() but they are all using a private database object from the Database class.
Are they all using the same connection behind the scenes (underneath ASP) or are they all actually using separate connections? And if in fact they are using different connections then is there a common design patterns that alleviates the pressure by passing around the same DB object?
It makes me a bit uncomfortable to know that every class is creating a new Database object and a new connection on top of that; however, if you were pulling data from a MS SQL database for the users and an Access (ugh) database for the Reviews this would be necessary.
On everyone of my pages I have an a include page at the top and at the bottom of the page
one is the database connection and one is for the database disconnection.
is there anyway I can automaticly connected to the database using a string without adding it to every page ?
I checked in IIS and I can add a footer but not a header, or anyway using global.asa file
Is there a function or a script that I can use to monitor the connections to my SQL database. I want to see if any of my connection objects aren't closed (I have many ASP files and it's easy to forget to code something like this: PHP Code:
MyConn.Close
set MyConn = nothing
What happens if a connection wasn't closed?
I am currently developing a coursework for uni that involves inserting some values into a Access database. I know how to do this, however I am trying to use different insert statements to insert data into different tables, however all the input field are on the same page. Code:
View Replies View RelatedI have a question on DB Connection. My ASP requires me to create 2 DB connections to 2 different database.
2004.mdb & Information.mdb. In this 2004.mdb, I have 12 tables(tbl1,tbl2...tbl12).
And in Information.mdb, I have a table called t_information. This table houses all the names of tables from 2004.mdb.
In my ASP page, there is a drop down list. As you can guess, this drop down list retrieves the values from table t_information that resides in Information.mdb.
When I select the table that I want to display & click the submit button, I will have to create connection to this 2004.mdb that has all the tables(tbl1..tbl12) and display the selected table. Am I right? So, to achieve the displaying of the selected data, I have to create connection to both 2004.mdb & Information.mdb right? Is that possible? I mean, can I really create/establish these 2 database connections on the same ASP page?
I really need advices on this people. Do hope to see replies here. And I understand that we can TableDef in Access? Can anyone explain to me what does TableDef do? And how to go about creating it?
already created a Database Util class using ASP Classic that they would be willing to share which prevents things such as:
-Replaces single tick with double tick so the SQL string is not compromised
-Prevents SQL injection
-Any other SQL prevention code that I am missing here
I have searched and found bits and pieces but I wanted to add this post to also find out what other items I should be concerned about with SQL that I do not have listed.

I have a situation where I have to update a single table with information from a bunch of fields. So I can explain better this is a sample table with some data... Code:
I am having trouble with structuring my query for searching using "LIKE". I
return no records with my current SQL statement.
Here is the string I am sending through ASP using VBScript as my language.
Other piece:

"SELECT * FROM LDSWSNames WHERE WSName LIKE '" & strClass & "' "
Output string from ASP:
SELECT * FROM LDSWSNames WHERE WSName LIKE 'KYLEXAD01'

I'm facing a crazy problem:

response.write spc

will not work, spc is empty.When I replace <abcd with ab<cd, then spc contains only ab.
Where do I make the mistake ?

View Replies View RelatedI am creating a search page and need help writing the code to build the sql
string.
I have 3 fields on the main page which a user can choose to enter search
terms in any of the 3 fields. My question is how do I write the logic so it
only includes the fields in the search criteria where the user has entered
anything.
Fields are
Production No
Production Title
Synopsis
The user may enter any, all or some of the search teams in the fields.
On the search page I am using lots of if conditions to build my sql string
like
strSQL = "Select * from Productions where "
now after where there are lots of permutations and combination like
production no could be empty or it could be filled in and the other fields
might be empty or filled in as well.
Does someone has a simple logic to build the correct sql String?

View Replies View RelatedI'm interested in building a graphical timeline for a series of tasks that are stored in a SQL Server 2000 database. The tasks reside within a table. We also have a table to track the history and date of status changes. Some of the status flags are as follows:
1 - In Progress.
2 - Awaiting Info.
3 - On review server.
For each task, using ASP or ASP.Net, I would like to be able to display a graphical timeline for each task, with the status changes denoted for a given date range.
Does anyone have any ideas on the best approach for this task?
I need to build an UPDATE statement that copies the values of roughly 40 fields from a table that stores standard or default values into a table of specific contracts. There are 8 or so fields in the source table that are not in the destination table. The remaining field names are identical in both tables.
How do I create a recordset of the field names I am interested in so that I can loop through it to build my UPDATE statement?

I am currently putting together an eCommerce site. I have almost everything
in place, but I am not happy with the category system for our products.
There are around 2500 products in a SQL Sever db, each assigned 1 of 300 odd
categories. Currently, I have statically built the category tree but wish to
automate this task as it is becoming increasingly difficult to manage.
I have googled plenty of info, specifically for ADO data shaping. Is this
the right route to take, especially considering each branch of the category
tree may differ in depth of categories? How exactly do other eCommerce sites
automate this task?
I would also want to be able to copy the category system that provides links
to previously selected categories i.e.
Category 1 > Sub Category 2 > Sub Category 3 > etc etc
Is this possible with the SHAPE command? Are there other methods of

I am particularly concerned about the database taking a major performance

performance? Considering I will be hosting on a shared server, I want to
make this as efficient as possible.
