I have the following code to select records from an access table based on a date range. The user is required to select a week ending date (Saturday) from a datetimepicker field.The date field in access is formatted as short.The values in the database range from 12/04/2009 to 2/05/2009. When I select datetimepicker as 2/05/2009 (i.e. 2 May 2008), no rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#26/04/2009# AND WeekDate <=#2/05/2009#)
However, if I select datetimepicker as 25/04/2009, the correct numbers of rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#19/04/2009# AND WeekDate <=#25/04/2009#)
Private Sub btnGetTSData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetTSData.Click
Dim dSelect As Date
dSelect = dtWkEnding.Value
Now what I want to do is on a button click, I want to search the database for a date range, lets say September/01/2010 thru September/30/2010. Then I want to pull all of the Pprice values and add them together to come up with an inventory parts cost for the month.
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 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 have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...
I am developing one desktop application using vb.net 2008 and Microsoft SQL Server 2005. fetching the data from database between a given range.
the date field in my table is of type VARCHAR(25) and the date format stored is dd-mm-yyyy. when I using the between clause in the SQL query then it is not giving all the data every time i.e. the date criteria in where clause is not working fine.
while my clients requirement is to keep the date format as dd-mm-yyyy and fetch the data according to the given range.
I search on the forum and found many queries to fetch the data by converting or type casting the date field within sql query but nothing worked.
The table structure that I am using is as follows
USE [Firm_master] GO /****** Object: Table [dbo].[tblTransaction] Script Date: 05/17/2011 21:49:11 ******/
I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ? [code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.
Ok, so I`ve been studying a bit of VB lately.. bought a few books and read lot`s of articles and seen hours of instructional videos, and I slightly start to get the hang of a few things.. :) I`ve recently started a fun little project, but I seem to lack a bit of knowledge to reach my goal. I`ll first try to describe my project:
I'm tring to create chart from Column B (to be X axis), and column D (Y axis).when I set it as range: .range("B":"D") - it'll take also column C.How can I set range for chart to be column B and D only??
I want to take my access database which i used in my project on visual studio2008 backup by selecting the local drive of my computer at the time of backup i choose the drive & there were i taken the backup i restore my database. Is is possible to take backup atomatically when i close my application.
my sql statement is returning null when when I compare date from access database and date entered in textbox in vb. seems to me that the two dates are of different format so null is returned from the select statement but how do I go about this.[code]
I'm looking for a way to use two DateTimePicker controls to select a range of hours and minutes within one day. That is, to basically select a 'starting time' and 'ending time'.
I started with two DateTimePicker controls with the custom format of h:mm tt. I tried adding (on ValueChanged), a check that made the selected 'starting time' will become the 'ending times' minimum and vice versa, the 'ending time' becoming the 'starting times' maximum
However, that approach didn't seem to work -- I was still able to select 11.00 AM on the 'ending time' and 1.00 PM on the 'starting time'. I have a feeling that the current day of the timestamp has something to do with it (e.g. the starting time is of the previous day, and therefore is less).
I thought about changing to a combo box of preset half hour intervals throughout the day; however the minutes need to be more flexible than that...
UPDATE: Dan's comment below answered this problem... This is the code I ended up with for reference; Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.
UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:
Here's my code:
Private Sub CheckForOverlap(myMonth As Messages.MyMonth) Dim am As New MyMonth() Dim amCollection As Messages.MyMonthCollection
I am trying to get a list of dates from a provided StartDate and EndDate in my database, and use these dates to link to dates in a database (to display another variable on the y-axis of the chart) and to populate the x-axis of a chart (with the list of dates). Is it possible to get a list of dates in VB and pass them into a chart this way?
i just want to ask how can i populate a listview n vb.net that has a is limited by a date from and date to.i have a datetimepicker for start date and datetimepicker for end date and i want do list all the entry of my database in listview that is within the range of the start date and end date.
I'm using ASP.NET/VB and I'm trying to insert a date and time into an Access date/time field, but I'm getting an error (Data type mismatch in criteria expression). Here's a simplified version of my code:
Dim myDate As Date = Now() Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (date_submitted) VALUES (?)", myConn) myIns1.Parameters.AddWithValue("@myDate", myDate) myIns1.ExecuteNonQuery()
Not sure why I'm getting the error, and not quite sure if this is even the correct way to approach inserting the current date. From looking at other similar questions it appears there are a few different ways to do this, but my technical knowledge is kind of limited so I'm having a hard time figuring it out (in other words deciphering the answers that use technical terms I know nothing about).
I am attempting to use the DateTimePicker and then add a day to each iteration in a For/Next loop. That seems to work fine and I can verify with msgbox that it is happening. However, I also need to write the date in string format to an Access database using INSERT INTO. However, when the code is ran, I get a "syntax error (missing operator)". Code is below. Can someone help please? I have tried all I know to do.(Please disregard the additional values in INSERT TO, I have verified they are working properly)
I have inherited a database from somebody who has passed away & I have been asked to look after it.The data is in an mde file which i can use vb to display records i need to report on.In the database is a field for dob which is date/time structureThe date in the database is 23/jan/1874If I display Rs("BirthDate").value i get 23/01/74If I say Dim Bdate as date="#" & Rs("BirthDate"),value & "#" & display Bdate, I get the same
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.
Im trying to use DateTimePicker function and save the date to an access database. Everything is working somewhat how I want it to but not 100% yet. Here is my problem. When the program is running if I click on the datetimepicker and select a date and click my save button the date IS saved to my access database as it should.
but if i run the program and don't ever click on the datetimepicker (because it is already on the correct current date) and click my save button the date doesn't get saved to the access database. The closest I have gotten was to enable the ShowCheckBox option, If i run the program this way and select the check box but dont select a date then it will save the date to my db.
But I really need it to be able to save the date to the db without the user ever clicking on the datetimepicker. Is it just a simple line I'm missing? Im pretty new to this but Ill try to explain anything the best I can if you have any further questions for me.
How can I save a date data type from vb.net to access that access have date/time in its data type and how can I retrieve it? I also want to use datediff to auto calculate the age to be shown in a textbox.
I am trying to alter a column in an Access database in VB2008 from date to text format using the SQL string as follows "ALTER TABLE receipts ALTER COLUMN Date CHAR(10)"but whether I Use TEXT, CHAR, VARCHAR or STRING, I get a Syntax Error when I run ExecuteNonQuery.
