View 6 RepliesThe SQL string won't return data from Access. I've tested this exact SQL String in Access and it works fine.First of all, Am I getting a SQL query from Access in the proper manner?Second... should I be using a stored procedure for this? Or is making a query from tables like this a good practice? Third, if I'm doing it right, why won't Access query return and fill my dataset?These are the results I'm getting.
Connection State = 1
Tables in Dataset = 0
Where am I going wrong?

View 3 RepliesThis is not a homework of mine and i had never tried ms access database with vb so i just gave it a shot. so this is my first time and i am just trying not asking anyone to complete my homework. I have been searching for this a lot on internet but couldn't find a solution to this so i decided to ask this question here.
i have this sql code. what i want to do is that create a basic login form where users puts it's username in the UsernameTextbox and Password in the PasswordTextbox. If the the information match then a message box appears saying that the user is valid and if the information does not exist, a mesage box appears saying the users is not valid. now everytime i execute(run) the code, i come up with this error: Syntax error (missing operator) in query expression ''UserName' = 'Admin' 'PassWord' = 'testing123''.
The field names(UserName, PassWord) are also correct they are same as in the database. the information put in the username and password textbox are correct and they match the information on the database. But i dont know why this error comes up.
My code module is the following:
Imports System.Data.OleDb
Public Class LoginForm1
' Cancel button
Private Sub Cancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel.Click

edit: i'm using VS 2010 I want to perform an SQL query based on certain criteria using the following string:
SQL = "Select * from tblTransactions " & _
" WHERE holding_PM_code='" & cbPMCode.Text & "'" & _
" AND transaction_status='Active'" & _
[Code]...
Should I pass a parameter in the query or shouldn't this suffice? edit2: i've checked the SQL and it does show the correct date format to search for (ie, dd/MM/yyyy)... but when I hover the mouse cursor over over 'dtiAsAtDate.Value' it comes up as '#mm/dd/yyyy#'.
I am trying to call a SELECT query (with parameters) in Access from VB.Net 2008. I am able to call queries without parameters using the code below. The problems are (1) how to apply the parameters to procName and (2) how to get a dataset returned. I have looked around the net for hours and have found some examples. However, they are all for ms access action (update, delete, etc) queries using ExecuteNonQuery which does not return a dataset.

Using VB2010, I am trying to insert a row into an Access 2010 database. The database has several tables, but right now, I'm just trying to insert a row into a standalone table in the database.
View 5 RepliesI have a program (below) which runs an SQL query on an Access database to bring back records based on the date a user selects. This issue seems to be that US date formats are the only date formats that SQL queries accept. I may be wrong, but this is my understanding. All my dates in the database are in EU date format (dd/mm/yyyy). What happens when i run my code is that I can not access a record with the date of 08/05/2010 unless the input date is 05/08/2010.

i have to update the values in my database some of them are integer, some string and some date (as you can infer from the formatting)
i am using the following query:

but its not working... i think there's a problem in formatting the date type variables

View 3 RepliesI have a select statement which was returning the required values but when I changed the OS date from English(US) to English(UK), it now returns null. I believe the problem is concerned with date since in the query am selecting values where the date from the database is the same as the date in a combobox but I don't know what else I can do. It almost looks like the dates in the combox and in the database are not the same and yet the date in the combobox is actually retrieved from the database and has been returning values fine until I changed the system date format.Here's my select command:
cmd4.CommandText = _
"SELECT sum(brought_qtty), recieved_qtty from brought_coffee, centre_weigh where brought_date=#" & _

I want a query for stockcalculation to show data as under:

how I can get the above information through a query on the above two tables to be displayed in a Listview.

I have a dataset with a table. The table has three columns.The first column is a combo box with 6 company names loaded in it. The second column will allow my user to enter monetary values which are spending from whatever company was selected in the first column.The third column will calculate a percentage.After putting the table on my form, I would like to go through the table as the user enter the values and add the monetary values of the second column if they belong to the same company.Meaning that for example every time company A is detected in the combo box, its spendings will be added and displayed in a textbox in a different form.Every time company B is selected in the combo box, its its spendings will also be added and displayed in a textbox in a different form.and so on, and so on for all 6 companies.

I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
I build xml in memory from the file, separate that into nodes for binding to different grids, works fine except the dataset is missing two tables and I can't find out why, the code below uses a stream but I've tried a ton of stuff by now, and, just using ds.ReadXml(path) doesn't work to get the proper nodes and drops all but the first major node: vs2008/vb.net project.
I believe what's going on is that the nodes have attributes ... none of the nodes that do come through have them, the "author" and "entrydate" nodes are being dropped from the string:
If (My.Computer.FileSystem.FileExists(pPath)) Then
xmlDom.xmlArchMaster(pPath, xml)
_default.ActiveSiteID = xmlDom.siteheaderNode.Attributes("id").Value
