I have a database in which I have to on a daily basis enter the information for that day. I would like to update this on a bi-hourly basis to prevent any possible data loss.
Using INSERT INTO, I create a new table line. Using UPDATE, I get an error on the inital creation of the table line.I am really unsure how to check to see if that line exists or if there is an easier way around this.
How can i check if a vlaue exists ? Sample to get the idea: Code:
set con=server.createobject("adodb.connection")
con.open "Menu1"
sTempquery ="Select * FROM Voorkeur Where gebruikersnaam = '"& Request.Servervariables("LOGON_USER") &"'"
Set autor=Server.CreateObject("adodb.recordset")
autor.Open STempquery, Con
The idea is that if the "LOGON_USER" does not exist in the Dbase he must execute code. How can i do that?
Using ASP with VBScript is there a clever way to easily check if a value exists in an array without looping through it?

View Replies View RelatedWe have two tables EmpProfile and holidaysrequest tables.
EmpProfile has fields
EmpNo
Firstname
Lastname etc
HolidayRequests has fields
EmpNo
FromDate
ToDate
holiday requests table stores the dates employees have booked as holidays.
I want to write a query which will be used by ASP page to display everyone
who have not booked 29th - 31st Dec as days off.
I have built a page that lists all our databases, the
users connected to each database, and what application
they are using. Because these databases are moved, or
removed from time to time I need to check if the database
still exists before trying to query it. Otherwise I get
funny SID errors when it tries to process this command:-
Conn4.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=CD;" & _
"User Id=username;" & _
"Password=password"
Can this be done in ASP or should I be querying the error
collection or something?
I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?
Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn
Dim aSubordinates
If not rs2.EOF then
aSubordinates = rs2.GetRows()
'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing
'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4
there is any way i can check if the database Exists. I mean from the code side. I dont want it to throw me any error thats the reason.

View Replies View RelatedI'm wanting to do a simple controlled voting page. I too our webserver off anonymous and everyone who accesses the website is a domain authenticated user. I've already done some control structure pages based on Request.ServerVariables("AUTH_USER"), which works great. That's also how I would do this page, in my basic thinking.
My idea is to have an access database with two tables. One table will have the vote written to it and the other table will have the AUTH_USER written to it when the employee casts their vote.
I'm wondering how I would do a test against that table to see if their name has already been written to the table. So, if an employee votes already, when they go to vote again, their user logon would be tested against all entries in the table and if it exists, the vote would not be written and they would be redirected to another page that politely tells them they've already voted.
I have a web page that creates dynamical forms, depending of what kind of product it regards. When the user has chosen a product, data is collected from SQL Server and a form is created.
Some forms contains check boxes and some not. My questions is: How can I check if someone has UNCHECKED a check box? Because if that happens, I want to delete that entry from the database.
Since a form just posts the value of a check box if it is checked, this causes a dilemma.
Any ideas, I can't be the first one having this problem?
I've got a form that adds a record to a database. What I want to do is on submit, look at the records in the database to make sure no value in a particular column matches what the individual is trying to submit.
More simply, Form A has a field called "collection" which inserts into the database column named "collection" I want to make sure that the value in the collection field hasn't been used.
What I want to know is how do you check if a record exists in a MSSQL database. When a user visits a page in my ASP app it picks up thier username and uses it later on in the app.
What I want to know is how do I say in asp and sql , do I have a record in my database for user "john smith"? Then I can shoose my next action according to weather or not the user exists. Make sense? Code:

View Replies View RelatedI have a database with two tables:
Table 1: Human
Table 2: Exempt
I have created the following code for creating a record, which works fine. But what I would like to do is to check if I add a record on the "Human" table to verify if the record number already exists on the "Exempt" table. I have already created an error handler for it to check if it exists within the same table which works fine. But I can get to do the rest. I created a separate file where I created two functions, but I don't think I did it right. Code:

View Replies View RelatedCan somebody check the insert statement i have written?Ofcourse it is giving error.But what i am trying to accomplish here is i want the records to be inserted and then after the records are inserted ,i want it to be sorted and then displayed onto the page.i modified my insert statement to accomplish the same ,but i am sure its totally wrong.
After performing insert..i want to display records in a ascending order..how do i do that?
here is my isnert statement: Code:
I'm using a database to store the products in a basket.
It's this scenario:
A visitor already has some products in his basket and wants add some new ones.
Now, first I want to check if the selected products aren't already in the database.
1. if they are -> update the product when the amount number is changed
2. if the product is not in the database then insert it.
I'm stuck at the point that I can't retrieve if the database is updated, so I can either stop the query or insert the new product.
Java has a statement like getUpdateCount(), but ASP/VBSCRIPT??
I want the fastest solution, i dont want to retrieve the data twice and compare them to check if it changed..
I have a server using a webapp built on classic ASP, and I use a library that creates/manipulates a datagrid-style display on the page.
I am displaying a large chart with sufficient data that it will likely be paged, and there are several columns that are toggles (using checkboxes for these, with the entire column having the same checkbox NAME, but different values depending on the record).
I have a piece of script that for loops through the records present on the page (determined by a collection of hidden form values), and then I need to check if the collection formed by a given column contains that value, something like the following (pseudo-code):
I have this page set up at www.kevinhall.org/headcount/headcount.asp
what is the easiest way to check where the user has entered a value
and submit the row to the db. Maybe i'm going about the form wrong.
Each box has its one name but I was hoping i could get around using a
request.form on each one and useing the isEmpty. Its so tedious and
non efficient there has to be an easier way.. Maybe with .net possibly?
Is it possible to, whilst inserting a new record, use a session variable from a previous page for one of the fields?
