Sql :: There Are Fewer Columns In The INSERT Isn't The Answer?
Jun 30, 2010
I have an application that converts one database to another and one of the functions I use is insert_Note below. This application has multipule threads all inserting diffrent data into the new database. The code below works for a number of inserts ranging between 24 and 120 but then fails with the error:There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.I you look at the code you will see that this cannot be the problem as the code works for some inserts but not all. What else can cause this error in a multithread applicationuld be welcome as I have spent three days on this and got no where!
*Public sub insert_Note
Dim sql As String
Dim cmd As New SqlClient.SqlCommand

I have a table in a data grid the columns are bound to the columns...
SQFT QTY WIDTH LENGTH
i also have added into the datagrid an unbound column called Yeild%.what i'm trying to do is the following formula
SQFT / (QTY * (width * length / 144) and have the result return the answer in the unbound yield column for that row represented as a percentage
So if SQFT = 178 QTY = 2 Width = 144 Length = 102 answer would be 0.87 (rounded)
so this would be 87%

I am trying to insert data into a grid with 3 columns, in VB6 you could select a grid's column number, something like this :
grid1.column=3
grid1.row=2
grid1.text ="hello"
how do you select the column in VB2008 as i can't see any similar command ?

There are plenty of SELECT (...) VALUES (...) statements and Parameters phrases to go with the VALUES. Those appear unhelpful to me as I have no form fields or datagrids and will be working with all the rows in a DataTable in a DataSet. Once started, this application will run to completion, writing as few as 10000 rows or as many as 250000 rows
My Task is to write out the contents of each specified DataColumn in the DataTable, one DataColumn at a time. The insert will also include the key columns and use the datetimestamp of the records as a criterion. Nulls in the specified columns are included.
My source is a DataTable, my target for the Insert is a "tall-skinny" table in an Access database. There is a smaller DataTable that is related to the source DataTable, if I was writing from within the AccDB I would use Joins. I have created a DataRelation, but have no idea how to use it in this context..
I have tried many different SQL statements but they all fail on Select. Here are snippets of the code:
'now, instantiate the specified DataTable from among the DataTables filled above
strDDTableNm = CStr(rsDDTblNms.Fields("Table_Name").Value)
Dim dtSrcTable As DataTable

My goal is to connect to my database either manually or using an sqladapater, and get information from two of my databases on sql server 2005. Then I want to take this information and on run-time begin to add/subtract/divide/multiply certain columns and place the information into other columns. I can do this in queries, however, I want to do it on run-time what is the best way to achieve this.I had some of this working, but I just want to start fresh and see how you would go about doing this.

I am using the following code to alter an table imported from an Excel spreadsheet
Dim SQL As String = "ALTER TABLE receipts ADD payee integer, account integer, category integer, reconciled boolean"
Dim dataread As New OleDb.OleDbCommand()
dataread.Connection = Connection1
[code]....
Both ExecuteNonQuery() actions yields the exception message {"Syntax error in field definition."}The error message does not happen with the first if the boolean column is not there (I tried Tes/No as a definition - but that also failed.The second query to modify the ID column from autonumber to integer I assume fails because it is a Primary KeyHas?

In the user input of a textbox I would like that the user can input a formula to make it easier for him. So instead of inputing 400 I would like the user to have the possibility to input as 8*50. Is there a command for vb2008 to calculate the answer of this formula inputed by a string ?

As this Loops round, the answer for formula will eventually become the same as what was input, X. How can I get the Loop to stop when it has the same answer twice in a row? The counter will count how many times it has had to Loop before finding the repeated answer.

TextBox4.Text = (intVarB * (-1)) + (((intVarB ^ 2 - (4 * (intVarA * intVarC))) ^ 0.5) / (2 * intVarA))
The Variables "IntVarA", IntVarB, and IntVarC are defined as public variables in a code module.

I am writing a program for FEMAP API interface in VB 2008 Express. Some API commands open user dialog boxes which requires yes or OKcancel inputs. So much for automation "Sendkeys" do not work, because code execution stalls at the line which opens the dialog boxes. I need stg that runs in parallel, watches for these dialog boxes, and sends the right keystroke at the right time.

I have several buttons in my form and they each need to add, subtract, divide and multiply certain values together but I seem to be having problems with this. I didn't expect anything to go wrong and its probably a rookie mistake, but take my first calculation for example; a user must enter a value in a textbox (txtDays) and and also when one of my various radio buttons are pressed a value shows in a label (lblDailyHireCharge). I now need a way of multiplying these values to give me my answer shown in a label. I have done this by adding a button when which pressed multiplies the txtDays value with the lblDailyHireCharge and then shows it in the label, however it keeps on showing "0" when i click it.
Below is my code, I am basically saying that the value of both of those figures is intDuration and that lblDuration is where I want it to go when the button is clicked.
Private Sub btnDuration_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDuration.Click
Dim intdays As Integer
Dim intDailyHireCharge As Integer
Dim intDuration As Integer
[Code] .....
