VS 2005 Parameterized Query Update?
May 15, 2009
As you may have seen in my other post, I have to switch over an all text SQL statement based database interaction program to using parameterized queries instead.I remember doing it this way in college but I don't seem to be able to recall one part of it. The program I wrote back then and some code samples here both point to doing the code as I did so far:
m_strSQL = "UPDATE [OWNER DATA] SET [FIRST NAME] = @strFName"
m_strSQL &= ",[LAST NAME] = @strLName"
Dim upCMD As New OleDb.OleDbCommand(m_strSQL, m_Connection)
upCMD.Parameters.Add("@strFName", OleDb.OleDbType.Char, 30, "[First Name]")
[Code]...
it ran the SQL statement and that's that. Can I just do that with a parameterized query too without using the adapter.update()? And for bonus points, why the heck did I use that command in my old college program cuz I sure don't know?

I added a query. FillByDate using Table Adapter which takes a date as input from the code.The query I have set is the following:
SELECT YMD, AIR_TEMP_AVG, AIR_TEMP_MIN, AIR_TEMP_MAX
FROM mytable
WHERE (YMD = :PARAM)

I have created a parameterized query in my tableadapter. Here is the SQL:
SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
why the query works in the Query Builder but not in the code?

statement = "SELECT OrderID, (SELECT VendName FROM Vendors WHERE Vendors.VendorID = Orders.VendorID) " &
",OrderDt, RcvdDt, OrderTotal " &
"FROM Orders " &
"WHERE VendName=? " &
"ORDER BY OrderDt DESC"
Dim cmd As New OleDbCommand(statement, connection)
cmd.Parameters.AddWithValue("VendName", txtVendorFilter.Text)
Dim reader As OleDbDataReader = cmd.ExecuteReader(CommandBehavior.Default)
I was trying to do this before by simply concatenating the textbox value right into the SQL and I was getting a "No values given for required parameters", and read that that I should use parameterized queries instead. So I tried this and it doesn't give me any errors, but the reader never has anything in it. I've never used parameterized queries before, so I'm a bit lost as to why this isn't working. I've changed the above code to account for OLEDB from what I briefly read on how it should work, and it's giving me the "no values given for required parameters" again.

I solved this issue in this thread but there still are issues with special chars. ie 'I thought by doing parameters that it would take care of any special chars for you. Well i am still getting mysql exceptions about syntax. I look at the string it is working with and it has a "'" in it.Why are they not working as I expect them to?

I wrote this little function to allow me to pass an ArrayList of Strings and then based on the table passed to pre-build a SQLCommand like so
INSERT INTO table` (`column`,`column`) VALUES (`value1`,`value2`);
The function for this is here:
Public Function _SQLInsertBuilder(ByVal values As ArrayList, ByVal Table As String) As String
Dim commandString As String
Dim columns As ArrayList = GetTables(Table)
commandString = "INSERT INTO `" & Table & "` ("
For Each column As String In columns
[Code] .....
Now I know that much like mysql_real_escape_string() VB.NET has a Parameter ability to make querys safer. How could I parameterize the values during the build of the string.

[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.

I'm getting the error: The parameterized query(@CustomerID, @ProductCode, @DateOpened) expects the parameter @ProductCode, which was not supplied.For one thing, my INSERT query has five parameters, not just the three listed in the error notice.
Another thing, I supplied @ProductCode in the AddWithValue statement.
Another thing is that I don't get the error when I change:
InsertCommand.Parameters.AddWithValue("@DateOpened", Date.Today.Date)

The Error:
Syntax error (missing operator) in query expression 'DeviceName = 001a'.

I think it might be something with the parameter symbol (?) and the WHERE clause but not sure..

I'm creating a form application using vb. I'm still new to this and I'm teaching myself via the internet so please don't be too mean. I wrote my code using queries that I created in visual studio. I don't quite remember how to create an update query and write the code to update different datagrids. I tried searching the forums, and I can't find anything that fits into the way I wrote my code. I have an update button that I want to use to save all the edited data in the form. Here's my code so far:
Public Class Form1
Private Sub Blsys_systemsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.Validate()

I need to run a query when I add/Change a value in my first column in a datagridview. When I add a value (a identifier from a table) in my first column, then I need the query to retrive the rest of the values in the table recordset. When I try to run a query, all i get is a query that updates my whole datagridview, and not only one row, with this code in the CellValueChanged module of the datagridview:
Me.myTableTableAdapter.FillBymyQuery(Me.myDatabaseDataSet.myTable, CType(DataGridView1.CurrentRow.Cells(0).Value, Integer))
Is there anyone who knows what I have to do, so I can add several rows to my datagridview, and let a query retrive my recordset based on my value in the first datagridview column?

I COMPLETELY understand how redundant this is but I NEED it.Upon users creating a User account which only contains the ID, Username, Password and CustomerID I must also have a record in Customers create itself but null everything and the User.User_Customer_ID must update to the newly created Customer.Customer_ID
I have everything working but this pesky update query. The ONLY thing it needs to do is change User.User_Customer_ID to Customer.Customer_ID I managed to story the User.User_ID in an integer called UserID and Customer.Customer_ID in an integer called CustomerID I have tried a million different ways with no success
