DB/Reporting :: Insert And Update From A Table In MSAccess
May 29, 2009
I'm trying to insert and update from a table in MSAccess I've declared everything: Connection, DataAdapter and Commands.I didn't use the Command Builder instead I supplied my own Queries.My problem is if I add three rows to my table all the three rows in my database have the same values from the first row. It seems like the parameters are stuck on the values from the first row. [code] I'm using a DataTable with my DataAdapter since I'm dealing with a single table.I'm filling the table with a parametrized query, and updating it with the same dataadapter.I'm adding rows to my datatable and manipulating the table through code. I know that my data is there and every row has it's own values, I can see them when I debug my program.
I'm trying to remember how to insert data in to a table. Here is my code
Code:
I get the error
Quote:
Number of query values and destination fields are not the same.
I also get some error about the Insert INTO part not being right somewhere. Am I doing this how you would do it, or how would you do something like this?
I have an access database with 3 tables, want to collect data from 2 and insert them into a new row in the third (although this seems redundant there are reasons for wanting it that way). I created a form and call the data from the two tables fine, once the form is filled I try to add a new row to the third but it will not add the row even though it is telling me that is has. When I open my access table the record is not there. I am new at this and just can't figure out why it won't work, I have tried several approaches the latest is
Code: Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Activate() Dim IDNUM As String = InputBox("Enter Student ID Number") 'storing the text entered in a string [Code] .....
I followed an example from a VB 2008 Wrox book on creating, binding and updating a data set but I am having a problem. The code is supposed to automatically generate the update/insert/delete statements for me (according to the book) but when I call the update command, the data is not saved.
Here is my code
Code: Imports System.Data Imports System.Data.SqlClient Public Class FrmAddExpenses
[Code]....
After the form is loaded, I change the EntryDate field (which is a DateTimePicker) and close the form which should save the change but it doesn't work.
I am working with SQL Server express 2008 And visual Basic 2008. Here's what I'm trying to do, if it is possible.
I am using an Insert query to create a new record in the table. A sequential ID number is inserted into the database when the query is run in Visual Basic.
I want to capture this ID number in a variable and use it immediately following the execution of the query.
Is this possible or do I have to capture the value in a second query.
I wrote some code to update the count of a field in a table, but it is very slow. So I'm trying to do it in a subquery to speed things up, but I'm not very good with subqueries. I'm getting the error "Subquery returned more than 1 value".
I have looked through the entire internet (well that's what it feels like) to find this out.Tables - Authors and Titles add new title must be linked to an author, so I need to check that the author exists, if so, update the titles table with the user data from the textboxes. If the author does not exist, I need to insert the author first & last name into the author table, then the title info into the title table.this is in VB, using ASP.NET, and my database is a file, I'm not using SQL server, just Visual Studio 2008.
Dim insertParameters As New ListDictionary() insertParameters.Add("ISBN", ISBNTextBox.Text) insertParameters.Add("Title", titleTextBox.Text)
I'm not so good in databases and SQL. At the moment, I have a interface of a simple payroll system as well as a database design. I got 4 tables consist of Employee, Payroll, Deduction and Salary as you can see in the picture link below. Btw, I'm using VB 2008 express edition and mysql 2008.
Interface Design: [URL] Database Design: [URL]
My question: How can I link them properly? did I link them properly? How can I save the data into 3 different table from the interface u can see.

I need to edit and add records to a shared MSAccess .mdb file residing on a server (actually a shared Public folder during development), preferably through an OleDBAdapter or OleDBConnection. I've been able to connect and read data from the database, but receive an "Operation must use an updateable query." error when trying to invoke the OleDBAdapter.Update({datatable}) method. The Update method works fine if I move the database (and connection) to my local C: drive, but fails when moved to the shared folder. Eventually, the shared .mdb file will need to reside on a server after development.
i want to transfer data from datagridview to msaccess table...but there is something wrong in this code.. im not finding a way to do that Try Dim MyConnection As System.Data.OleDb.OleDbConnection Dim q As String Dim cmd As OleDbCommand[code]......
I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I am trying to export the contents of Array to Microsoft Access table. But as of now i could do it via creating a text file in the local HDD. I would like to find a solution bypassing this step.
I want to compress an ms access database using vb.net. If the database is open this fails. How can I close the database, compress it, then reopen the database using vb.net code to accomplish this. I've already successfully written the code for compression, but I can't find anything on closing the database while leaving ms access open.
For speed, I've decided to use temporary tables as the recordsource for a report. The problem occurs when I try and tidy up after the report is closed by trying to drop the temp table. Trying to do this using database.execute "DROP TABLE x" where x is the name of the temp table. Get a Run-time 3211 error that the table still has locks. I figured that any locks generated by the report would be dropped at least by the Deactivate event, but that doesn't seem to be the case. how to use a temp table in the report withot incurring an enduring table lock? The report is the sole user.
I used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)
