I want to retrieve query from MS.Access database criteria is between some date range,but I get the following error when execute my reader:Syntax error in date in query expression 'D_ate BETWEEN # @DateFrom # AND # @DateTo #'.
Dim StrSQL As String StrSQL = "Select * from Pla_Comp Where D_ate BETWEEN # @DateFrom # AND # @DateTo #" myCommand = New OleDbCommand(strSQL, conn)
I've been running into some errors with converting strings to dates in the following code. I have recently added the intcall.Value = DateTime.Parse(txtIntCallDate.Text) function which had gotten rid of the error message, however the records are not being updated, any of them on the form. Prior to this the strings were being updated just fine. As long as there is a date entered on the form there is no error, if it's left blank i get the "Problem converting string to datetime"
So basically, I'm getting date information from the user and trying to convert it into a date format, and show it to the user in a text box which is obviously named "DisplayArrDate", and "DispArrDate" is a date variable and "MonthArr" & "DayArr" & "YearArr" are strings which are always numbers because they are selected from a drop down combo box.
Now, the code works perfectly on my computer and some others, but for some unknown reason, on some computers, even if they have the same local date settings, it gives me the error: "Conversion from string "4/13/2009" to type 'Date' is not valid.", that's just one example, where "13" is obviously the day. I use the month/day/year format because, in the toturial I'm reading, it tells me, that no matter my local date settings, when using VB 2008, the month/day/year format should always be used and it will display a date in the local format automatically. It seems that on some computers, this isn't the case, and the month/day format is creating errors.
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#'.
For some reason every time I execute the code, it gives me the error "No value given for one or more required parameters" and it points to the ExecuteNonQuery. Below is the relevant code I have.
Public Function sqlUpdate(ByVal varBalance As Double, ByVal varWithdrawlAmount As Double) As Double Dim dbCon As New OleDb.OleDbConnection dbCon.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = dbATM.mdb" Dim query As String Dim cmdUpdate As New OleDb.OleDbCommand dbCon.Open() varBalance = varBalance -
I 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.
Dim con As New OleDb.OleDbConnection Dim com2 As New OleDbCommand Dim constring As String = ConfigurationManager.ConnectionStrings("esourcecon").ConnectionString con = New OleDbConnection(constring) com2 = New OleDbCommand("UPDATE Customer SET CName = @CName, CAdd= @CAdd, CTel= @CTel, Cmob= @CMob WHERE CName='" & C1.Text & "' ", con)

I have an issue with calculating a total from my dataset. For some reason the number of plates produced on the StartDate is not being added to the TotalPlates in my program.Here is my query and calculation of total plates produced:
Dim Plates_Query As String = _ "SELECT *" & _ "FROM [PlateHistory_Query] WHERE (PlateDate) BETWEEN #Start# AND #End#"
I 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=#" & _ dtComb.Text.Trim & "#" & _[code].......
I am trying to bind an Access database to a MSChart control in VB Net 2008. I have a test database populated with four fields SAMPLE-DateTime, Values-Number, MAX-Number and MIN-Number. I'd like to only display the rows that fall within a specific date range but I'm running into a problem when i try to execute the following command:
I am just creating an update programme that will update another one of my programmes. I have one folder that has got different layers of sub folders and files at each different level. I have got the following code to do this:
cmdUpdate.Enabled = False cmdSkipUpdate.Enabled = False Dim strServer As String
Im trying to learn as I go and reached a sticking point that I'm having a problem finding a direct answer to on the web I want to refine a query and update a record (or records if possable) Notes are in the following code
If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.
Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?
In the TableAdapter configuration wizard I am using this query:
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent FROM Attendance WHERE (DateOfClass BETWEEN #5/1/2010# AND #5/30/2010#)
Can tell me the correct syntax to change the #5/1/2010# AND #5/30/2010# so the WHERE clause uses dteStartDate AND dteStartDate which are date variables ?
I tried this but it tells me I need to use the to_date function. dteStartDate is already a date variable so I know my syntax is wrong.
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent FROM Attendance WHERE (DateOfClass BETWEEN #" & dteStartDate & "# AND #" & dteEndDate & "#)
I am trying to update a SQL Server database Date field.When the user enters the date they enter 02 Oct 2010.When I pick up the DateTimePicker.Value it is 10/02/2010 00:00:00. I need to get the value to read 02/10/2010 00:00:00 How do I get the value to be in this format?
I want to update a date field in my table when a record is updated to reflect when the last update was made. I have this for the parameter: objEXTCommand.Parameters.AddWithValue("@entryDate", Now.Date)
However, this inserts the Date and a time of "12:00:00". I want the date and current system time. I've gone about several ways, but none seem to work. I try this: [Code]
