I need some help working with an OleDbCommand Statement existing statement
OleDb.OleDbCommand("Select *, (([AddressDisplay])&', '&([City])) AS Address
The City is stored in database with the city name and an additional abbreviation added. I need to get rid of the abbreviation, if possible.I DONT control the database its from a 3rd party.
Example: Houston[HST] I need to remove the [HST]
Can this be done? Either in the command statement of perhaps in the displaymember of the combobox that reads the database?
I am getting a syntax error missing operator, I have tried this so many times by eyes are crossed can someone spot my mistake?

I am getting an error: OleDbCommand.Prepare method requires all parameters to have an explicitly set type.
on the last line of the code below.I have seen things saying you have to set the datatype of each parameter but how can i do that when it being generated by the command builder?
MVC3 VB.NET application. I have the below section of code in a function. This code is supposed to only fire if the handout1 is not nothing. But for some reason it is going into the then block when the handout1 is nothing in the database... I have tried a hundred different ways of checking but it is still trying to run that line of code even when there is nothing to assign to it....
I am creating a feature in my application that will allow a logged in user to add additional users to be logged in. The usernames and passwords are kept in a single database created in Access 2007. The table has 3 columns: ID, UserName, and Password. I am trying to insert user-inputted data through a TableAdapter function in a DataSet. It has worked once but for some reason it stopped working, and I can't figure out why.
Calling the TableAdapter function... Me.UsersTableAdapter1.AddUser(Me.txtID.Text, Me.txtUsername.Text, Me.txtPassword.Text)
[Code].....
Visual Studio isn't throwing any errors my way or anything so I am not sure what's going on here. The fact that the code worked once but isn't working now is also confusing, and I don't recall making any changes related to this feature since it worked that one time.
Conversion failed when converting the varchar value '17, 18' to data type int. Which is the same error message I get when I run my application. So I guess somewhere along the line, when passing those values in the parameterized query, they are being passed as string literals with quotes around them, instead of integer values separated by commas. How do I add the string that I obtain as the argument for this subprocedure into my sql query's parameter such that they do not get passed as string literals with quotation marks around them?
I have form1 and form2. On form 2 i have 2 combo boxes where the user is asked to make selections. once back on form1 i try to use those selections as part of an if statement but although i should be triggring them it does not. I cannot figure this out. I have set up test variables and msgboxes along the way to test this.
The code excecutes. I have double checked the variables on form 2. They just do not trigger a response that will enter the if statements even though it looks like they should. I have double checked that test1 and test 2 are grabbing the variables from form 2
test1 is "Male" test2 is "10 - 19"
When the code excecutes i never get to the msgbox("Age") line of code. I have also tried taking the spaces out of the strings with no luck as well.
I made a smallprogramm. Each Q is at the top of the Form.vb right under the Public Class.Each A is declared in the Private Sub where the given A is matched with the stored Q. Each A looks like this: DIM Answer1 As String = "Answer" and so on. I would like to use just one DIM statement for all the answers.
I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.

I am converting old VB6 code to VB.NET with ADO.NET (OleDB). This is my query that will create a blank table when ran in VB.NET, but then works when ran directly in Access. This code presumably also works in VB6, as I am using the same SQL:
SELECT qryAsOf.name, qryAsOf.type, 0 as opt, 0 as swap INTO qryCon FROM qryAsOf LEFT JOIN qryLinked on qryAsOf.c = qryLinked.lc
I feel like this has something to do with the left join and select into being together, but like I said it is only VB that has an issue with it, Access handles it perfectly.Without the INTO line, this query returns all 600+ rows.
This DOES NOT WORK:
cm.CommandText = "CREATE TABLE qryCon (etc...)" cm.ExecuteNonQuery() cm.CommandText = "INSERT INTO qryCon SELECT ..." '(rest of query above without INTO line) cm.ExecuteNonQuery
This DOES WORK:
cm.CommandText = "CREATE PROC qryCon AS SELECT ..." '(same select as above without INTO, again) cm.ExecuteNonQuery
The CREATE PROC that does work is fine, except I need to insert data into it later, so I get errors about how I need an updatable table. I really want the end qryCon to be a table, but I can't seem to get that to work :(
*However, when I do something like this (using the stored proc (renamed) above which, if viewed in Access, is full of data)
cm.CommandText = "SELECT * FROM storedProc" dr = cm.ExecuteReader
[code]....
This DOES NOT WORK! By the way, I removed the concatenation in the query for readability. It is correct in the actual project.
Im working on an access database, and I want to know how can I fix the code below so that I could display the correct information to the user. The problem is, I want to display an error message if the oledbcommand did not succeed.
created a database and I am able to read from the database into VB and also able to create a new set of feilds. I do needte a set of records, can't seem to find the right code.The access database has 4 columns one of which is a unique code (column name is 'code') that relates to each different item so I would have the user put in the code to the textbox and then the programme will delete the set of records corresponding to that code
Having trouble importing a value from a .csv file to a .csv file. This this done because data needs to be massaged and the data file renamed. This is a user interface. Do not want to have the user touch the .csv in any way except upload to the application so the applicaiton can do manipulation. Either way here is the issue.
There is a column in the original .csv file that contains a zip code. The first row of the .csv has a value of 17003 in the zip code column. In the second row of the .csv the zip code column has a value of 11746-9984. The value in the zip code column from the second row always comes back as a Null value. My guess is that the OleDbDataAdapter is defining some kind of Schema. Again, the first row containing the zip code column probably insists the value must be numeric. When the data table field is established it probably gets defined as numeric. If that is true and the second row of the .csv zip code column is not numeric that must cause the zip code value to be Null.[code]...
I'm using the following code to work out the next unique Order Number in an access database. ServerDB is a "System.Data.OleDb.OleDbConnection"
Dim command As New OleDb.OleDbCommand("", serverDB) command.CommandText = "SELECT max (ORDERNO) FROM WORKORDR" iOrder = command.ExecuteScalar() NewOrderNo = (iOrder + 1)
If I subsequently create a WORKORDR (using a different DB connection), the code will not pick up the new "next order number."e.g.
will return the same value to both iFoo and iFoo2. If I Close and then reopen serverDB, as part of the "NewOrderNo" function, then it works. iFoo and iFoo2 will be correct. Is there any way to force a "System.Data.OleDb.OleDbConnection" to refresh the database in this situation without closing and reopening the connection. e.g. Is there anything equivalent to serverdb.refresh or serverdb.FlushCache
How I create the order.I wondered if this could be caused by not updating my transactions after creating the order. I'm using an XSD for the order creation, and the code I use to create the record is ...
Sub CreateNewWorkOrderWithNumber(ByVal iNewOrder As Integer) Dim OrderDS As New CNC Dim OrderAdapter As New CNCTableAdapters.WORKORDRTableAdapter
I have an ACE OleDb connection to an accdb file that�s working well but I�m mystified by something I recently discovered when using named parameters. Order of adding of parameters overrides the parameter names. I see in the MSDN that is states when in "Text" mode named parameters is not supported. My testing has proven this to be the case. The example below puts "Value 2 in Field1 and "Value 1" in Field2. In fact I could change @value2 to @blahblah and it works.
Dim command As New OleDb.OleDbCommand("INSERT INTO Results(Field1,Field2) Values(@value1,@value2)", con) command.Parameters.AddWithValue("@value2, "Value 2") command.Parameters.AddWithValue("@value1", "Value 1")
what is text mode and how do I change it and what other types are there? According to John McIlhinney�s earlier explanation things like date variables are added in a binary fashion including support for DBNull. So this is not "Text" so how am I sending binary data to a Db in Text mode? I�m just not getting why it supports names when it ignores them. Is it simply the case that there is no way to add parameters out of order in my case?If adding out of order is impossible should my command use some other syntax? I see other syntax that just uses question marks in the command dim for the Values section. EG "Values(?,?)".
Is there a way of adding parameters without names?In general I�d love to hear someone to explain this so I can understand the inner workings here a little better and have a little more confidence in what I�m doing here. I can fix my code to work but I feel like an idiot using parameter names that are ignored. I just know I�m doing something wrong even if it works.
I'm trying to add a new table to a database connected via MS Jet driver. When I run the following Code, the error I get is:
