Insert Command - Record Is Not Added Without Any Type Of Error
Jun 22, 2010
I am a beginning programmer and am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]
I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens.

The application contains a GridView which displays the records of a user table from my created datable. The database is an Sql server database.
The code below inserts data into one table and through the built in function @@Identity to insert the most recently added record id (tt_id) from the trainingTbl table and inserting that record id into the userAssessmentTbl. Adding the identity to the second userAssessmentTbl table works fine.
[code...]
The issue I'm having seems to be centered on how I insert a uniqueidenifier from a GridView into a userAssessmentTbl database!
And how, I guess using a loop I can insert the UserId records from that Gridview (GridView1) into the userAssessmentTbl table along with the looped id from the @@Identity.
This part of the insert parameter seems to be incorrect:
[code...]
And the error I'm met with is: 'Conversion failed when converting from a character string to uniqueidentifier.'
I've also tried it like this:
[code...]
And im met with the error: 'Operand type clash: int is incompatible with uniqueidentifier'
The qusetion has slightly changed to how do I Insert a String into SQL DB Where DataType Is Uniqueidentifier?
I'm running VB 2008 express, I'm connected to a MS access 2007 database. I get the following error
Syntax error in INSERT INTO statement.My code is as follows
Imports System.Data Imports System.Data.OleDb Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I'm using a form to throw info straight into a database. i know it isn't the best way but i'm new and all other implementations have confused me (i've been reading and watching tutorials for 2 weeks) but anyway i'm going to take the info straight from the form.
mports System Imports System.Data Imports System.Data.SqlClient
I'm only working with VB.NET since 2 months now and I have a run time error (invalid syntax around '0') which I cannot fix (so it seems).
If the button NCOSubmit (see below) is clicked I want to send all data to the SQL database through the sqlText string. Currently I put a break point under the code presented below, so the error cannot come from there.
Private Sub NCOSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NCOSubmit.Click Dim sqlText As String = ""
I am trying to export my datagridview rows to an access database:
Dim objConnection As OleDbConnection Dim objCmd As OleDbCommand Dim strConnection As String Dim strSQL As String strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
I have an Access DB that lists customer details in a datagrid and in textboxes, when I use the edit button I can edit in the textboxes and when I click save the record is saved and shows in the datagrid. But when I exit the program I get "Syntax error in update command" Im not sure why because there are no errors in the error pane at the bottom
This is the code for save button Private Sub btnSave_Click(ByVal sender As Object, ByVal [Code] .....
I am trying to save data to my table but i am getting a error message.Here is the code. It tells me a parameter is missing. The amount of fields in the table is the same as the fields i am inserting into.
''''''''''''''''''''''''''''''' '' Now the ingredient table ''''''''''''''''''''''''''''''''''''''''' Try
My system still show the "record has been added" and save/insert the data even if i chose the "no" button. I think I miss something on our codes. Should I add something?
Here's the scenario: If "Yes" (button) will be clicked, it'll save the data and clear the fields. If "no" (button), it'll clear the fields and shouldn't save anything.
Here are the codes:
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click If newname.Text = "" Or newaddress.Text = "" Then MsgBox("Please fill-up all the requirements.", vbExclamation, "*** System") Else
I seem to be having a problem when attempting to insert a new record into my database through vb.net. From what I can gather, there seems to be an error in the code that the command builder (cBuilder) is creating for me. [code]...
For the life of me I cannot find the solution to this error. All field lengths match the length of the SQL Server data field. Here is the insert code I am using... the same to the code that is used elsewhere in the program.SQL Server Express 2008 R2 and VB 2010 SP1.
Dim blnInputError As Boolean = False Dim blnPrimaryKeyError As Boolean = False Dim blnIsError As Boolean = False[code].........
I have a access database with these columns. USER_ID,COUNT,TIMES
Let say the current record is this: USER_ID,COUNT,TIMES STEVE20,24,1.5
Now I want to updated the current count record and times, but before updating I want the old record to be added to the new record. What should be my query?
When ever I try to update a record from data grid using a dataAdapter record it always showing ' update requires a valid insert command when passed data row collection with new rows' From specific sql server Table only. Resulting me holding up a project.
Dim edit1 As OleDbCommand = New OleDbCommand("select * from [exporter] where exp_id='" & t1.Text & "'", con1)
now:-
t1 is a textbox
and in my table exp_id is "Number" now when i run this i get an error at the time executing reader (Data type mismatch in criteria expression.) but when i change exp_id properties to "Text" it run's properly
I have looked at this for hours and can't seem to figure out what is causing the datatype mismatch. I am trying to insert from asp.net to a access database
insert statement:(ignore the poor practice with the concat parameters)
Dim BSSQL As String = "insert into bodyshop (startdate, enddate, frontbump, rearbump, touchup, other, vehicleid)" & _ "values('" & StartDateBodyShopTXT.Text & "','" & FinishDateBodyShopTXT.Text & "','" &
[code]....
here is a snapshot of the table:the format of the yes/no fields is "true/false"
User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
could someone tell me what i am doing wrong in this codeProtected Sub insert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Insert.Click
I'm using the following code to add a new record to a table in the database. However, the DataGridviewthat's binded to the DataTable, isn't getting refreshed /updated.[code]...
I wana know how can i use a value from a sql table that i added from another form?It basically supposed to validate that whatever was the last recorded added in the other form(eg formA) , i must then use those same values from the sql , into another form(eg formB).If i type a value in the textbox( in formB), it basically must validate that, the value i typed in, is not the record that was enterd in the other form(formA) (the last record added in that form)
Here is my coding that i did: Dim conmid As New SqlClient.SqlConnection("Data Source=CHETS-TOSHIBASQLEXPRESS;Initial Catalog=PlanetDiscLibrary;Integrated Security=True")
on form1 , i have a combobox and a label. on form 2 , i have a checkbox , a textbox , and a label . in the textbox i input the name to be added to form 1 by combobox checked, and the label has a folder directory.
i can add the new item to the combobox on form 1, from the checked box on form 2. what i can't seem to figure out, is how to get the form1.combobox newly added item to show the folder directory label from form 2 on the form1's directory label when i click on the combobox item..
I have written a code which adds some information to a database. No problem with that since the records get inside the database. My problem is that the record I added always shows up on my Search. I tried changing the variables so that none will have the same names between the two forms but it still shows.Example:
1. I added a record of a book which has an id of 1, name of Cisco, and total of 50. I added it thru the debug function.
2. I added a record of a book which has an id of 2, name of Link, and total of 30. This time, I added it directly on the database file itself.
2. I created a search button which will show records depending on the input of the user.If I type "1" for the ID, the first record will appear on the datagrid. If I type "2" for the ID, both records will appear. If I type "3" which I doesn't have any record with, the FIRST record will still appear. To summarize it, the record that I added through the program itself will always show up on the query results, no matter what I type into.
Dim command As New OleDb.OleDbCommand Dim adapter2 As New OleDb.OleDbDataAdapter Dim bkId, bkTtl As Integer
my form isn't showing my newly added records in the database but when i close it and then open again it will show. I want to know how to add refresh button and it will automatically refresh itself..
When new record is added, I want the vb to look at the last record in the database, look at its id, add 1 to it (+1) and generate a new number and display it in the IDTextBox.
I have a Combo box that list invoice numbers. When a user creates a new invoice I would like the Combo box to display that number and not the first number as it currently does
I don't even know where to start with adding a command to a newly added item in the context menu. So much work to do and so many choices to choose from...
I'm trying to add a new record to my database but i keep getting the message - "conversion from type DBnull to type string is not valid". I think its something to do with the Employee ID when VB attempts to save it to the database my code is below
Imports System.Data.OleDb Public Class Add Private Sub DisplayRow()
