Sql - Failing To Read Data From An Excel Sheet With Where Clause In Select Statement?
May 4, 2012
I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?
I have an excel sheet that contains 25000 phone numbers listed in one cell with no sorting order. I want to create a small windows application that can read the sheet and return the total number of the phone numbers and how many duplicate numbers as well as the number of times of repetitions. How I can resolve this issue? What is the best way to approach it? I'm using VS 2008 and VB.Net.
I'm using a select statement to select data from an Access DB but I'm using. I can select the data perfectly but when I use the Where clause it doesn't select any data and the data I'm looking is in the DB.

I have a month and a year dropdownlist which give me the following string 01/2012 The date format in my db is "2012-01-01 00:00:00" but when I select an individual date and put it in a message box it converts to "01/01/2012"
I've altered my select statement below to reflect the converted date. However Im still not given the correct details. Any ideas? Is there a particular format that I need to use when dealing with a timestamp field? Can I even use the "Right" function in a select statement?
Dim newRecordDate As String = val1 & "/" & ComboBox2.SelectedValue Dim sql2 As String = "Select CatA, CatB, CatC, Cost, Currency, MarketingCode, Comment, RecordDate from vw_tblP_Usage_Details where puid = '" & puid & "' right(RecordDate, 7) = '" & newRecordDate & "'"
Dim executeB As Boolean Select Case myVariable Case "a" 'some code Case "b" 'some code Case Else End Select
If myVariable is "a", control will go into the first case statement. Now let's say if myVariable = "a", but inside a's case block, I find that executeB is true, is it then possible to jump to the second case?
I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.
I post a question similar to this a few days ago, but nobody answer. Now I modify my request a little bit, I want to read an excel file using VB.NET program. I know the logic below can do this. The logic is shown below.
But I have a question. This logic needs the worksheet name, but usually my application doesn't have this information, the worksheet name cannot be hardcoding. I have 2 request:Can I always upload the first sheet from the selected excel file. (ACCESS can do this without knowing the worksheet name).
I am importing an excel sheet into my sql database. Everything works fine, but I would like to read the column header in as static value. Not sure how to do this. Here is the code I am using to read the sheet in:

I have managed to read a sheet from a excel workbook and pop it into a datatable.
Public Function GetSheet(ByVal SheetName As String) As DataTable Try MyDataTable.Clear()
[Code]....
My understanding is that if I make changes in the datagridview it is reflected in the datatable.
So now I want to write the updated datatable back to the appropriate worksheet.
I have read about "insert into" or "update" etc but it is very specific columns and rows.
One other thing, when I set the datagridview datasource as the datatable I get about 9 other columns such as TABLE_SCHEMA TABLE_TYPE etc. Any pointers wher thay are coming from and maybe how to get rid ofthem?

to setup daily import of data from excel file into SQL database - preferrably through Visual Studio project (Visual Basic 2008). The problem is that I wouldn't know the name of the excel sheet. The excel file is created daily from different software and depending on amount of data on certain day - could have the sheet named as "Rows 1 to 5000" or "Rows 1 to 15582" and so on - therefore can't use 'Sheet1'.
