i am trying to run the code above but once the date filter ([DocumentDate] = '12/10/2009 00:00:00'") is applied the results count = 0 any idears how to filter an SQL database between 2 dates.
I have a code which can get the MAX value of distinct "SYSID" field. Now, I plan to add a data filtering by time - Start and End time. I have tried but getting all sorts of error and can't get what I'm after for. So the program should do the data filtering (data >=starttime and data <=endtime) first before getting the max value of "SYSID"
Below is my
Private Sub Get_Max()
Dim ci As New CultureInfo(CultureInfo.InvariantCulture.LCID, True)
Dim dtfi As New DateTimeFormatInfo()
dtfi.ShortDatePattern = "MM/dd/yyyy"
dtfi.ShortTimePattern = "hh.mm.ss"

I'm using EPPlus to create Excel reports. Now i'm trying to create a Pivot with a DateTime PageField, so that the user can filter the period he want to see by himself. But although i can filter this for year,month or days in the according data worksheet by default, i don't get it working in the Pivot.
Here is what i have:
Dim wsPivot = excel.Workbook.Worksheets.Add("Pivot")
Dim wsData = excel.Workbook.Worksheets.Add("Data")
Dim source = workSheet.GetDataSource

I'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?
View 4 RepliesI'm trying to filter my access database and when I "search" by name, it works, but when I search by policy number it doesn't seem to work.

im just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.
When I want to insert datetime to database. Sometime is good but sometime is error. This is the code:
datetimesales = format(now,"dd/MM/yyyy hh:mm")
When I insert a datetime into a datetime field in a SQL Database I only get for example 22/04/2012 06:31:33 instead of 22/04/2012 18:31:33 no matter how I format the field either in Vb or on date time on pc I only get am times
MyArray(MyClientHandles(f), 4) = Format(Now, "yyyy-MM-dd HH:mm:ss")
This is my typical code & have tried many formats the string shows as correct when looked at on breakpoint.
I am using a sql server database and i am storing the time value in the datetime variable. I am developing a booking system application in vb.net. When I want to view already made bookings using datagridview and by implementing dataadapter and dataset it shows the time column with system date which was saved with time when the record was inserted. Now I want to view only time in the Time field when extracting the data....What should i do now??
View 3 RepliesI need to have a property that is a nullable date as the datestamp is used for when a process is completed. If there is no date this is a way to determine if the process has occurred. I have created a Nuallable DateTime property (DateTime?) However when I try to assign a value from my database entity (when debugged has a date value) I am not thrown an exception however my property still reads a null value after assignment. How can I get a DateTime? type to accept a DateTime value?
I thought this would do the trick
_object.DateStamp (type = DateTime?) =
_entity.DateStamp (Type = DateTime?, Value = DateTime) o
Or for more understandable syntax
Ctype(object.DateStamp, DateTime?) = Ctype(entity.DateStamp, DateTime?)
Strange thing is I can assign the properties value like this.
Ctype(object.DateStamp, DateTime?) = Now
I am using LinQ Entities.
I have a problem in retrieving dateTime object from the database. I have this :
Return CBO.FillCollection(Of ObjectInfo)(CType(DataProvider.Instance().ExecuteReader("sp_SelectAll"), IDataReader))
Then When I want to display the date from the collection I get from the stored procedure. the date was truncated. It shows only the timein the ObjectInfo..there is a field call _mydate as DateTime.

I am trying to insert Default dateTime into my databse however when I run this code it stores date but stores time as 10:00:00, Is there a way I can store the time without the seconds so it is like 10:00?
I have an application in which I have one textbox (in this one I write a date like 23.07.2010 ) and a combobox in which I insert a time from the list of combobox (like 12:30, 14:45, etc). I want that when I press a button to send this datetime value in a column of an sql database. I want to send something like (in VB.NET)
sql=" INSERT INTO table_name (column1, column2, date_time_column) values ( val1, val2, '23.07.2010 12:30') "
execute(sql)
So, I have problems when I want to send date/time into sql tables because of the different Regional Settings.
I am not sure if this should be in the SQL or vb.net section.But, Basically I have a vb.net application from where I insert a datetime field into the SQL Server Database. Now for some reason the SQL server field(which is datetime) will not display AM/PM, I have referred this link where my code looks like this:
Dim dateToDisplay As DateTime = DateTime.Now dsNewRow.Item("date_created") = dateToDisplay.ToString("MM.dd.yyyy hh:mm:ss tt")
I tried stepping into the code by debugging and it seems to be inserting the PM but is not displayed in the table QuotedateToDisplay#8/12/2011 6:01:06 PM#Date

I am inserting data from vb.net to oracle but I am unable to insert datetime except date into oracle. I want to insert date and also time of entry into database:
cmd.Parameters.Add(":STARTING_DATE", (OleDb.OleDbType.[Date].))
cmd.Parameters(":STARTING_DATE").Value = DateTime.Now()
cmd.Parameters(":STARTING_DATE").Value = txtStartDate.Text
Which method would be fastest / most efficient?
A) Read all data (822 rows) including those I do not need then filter / output those I do
B) 3 Round trips to the db using params filled via the last query to select only the data I need

View 4 RepliesI'm trying to access the SQL DB I have designed within my project in Visual Basic 2010 (.NET code seems to work for me 99% of the time) at runtime so that a user can select a method by which to filter a DataGridView.I have a fantasy football draft application that fills the DGV from a Table Adapter. The database is named NFLPlayerDataBase.mdf, the dataset used to fill the DGV is TabNFLPlayers11BindingSource1, the table adapter is TabNFLPlayers11Table Adapter1. The DGV is dgvDraft. Idk if that helps at all.If the user wants to look at only RBs while making their draft choice, I want them to be able to select RB from a drop-down and have the DGV be filled with the query that selects only RBs from the table. I have the drop-down already set and am able to fill in the DGV when the form initializes. I just can't get it to fill with the query request for a specified position.The table I'm looking to use from the .mdf is tabNFLPlayers11 and the column header that will be searched through the filter is "Position." Options are QB/RB/WR/TE/K/DST and will be selected by the user from a drop-down.I cannot find a way to even open the connection whenever I change the value of the drop-down.

I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción
FROM Categorías
WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..
