Select Fieldname From Tablename Where FieldLink ='1007'?
May 15, 2009
Am a bit confused on a basic select statement.Select Fieldname from Tablename Where FieldLink ='1007'
Nothing special.Now I pass into a sub that populates a combobox for me, but I get an error message - Index was outside the bounds of the array. This happens on the line when trying to add the data to the combobox But, if I change it to
Select * from Tablename where FieldLink = '1007' it will work fine, but returning the wrong field data.
Am I missing something. Procedure below that I using to populate the combobox

I created a new project. I copied files from the original VS 2008 project into the new VS 2010 an used "include" in VS 2010.I get an error saying "Error 108 Maximum number of errors has been exceeded."
It seems that EVERY field in the webformsuser-controlsASCX's has the error message "fieldName' is not a member of".I tried a delete the contents of the ASCX and ASCX.vb for a specific ASCX. Compiled and that page had no errors (although the other pages did). Copied back the contents ASCX and compiled (although the other pages did). That page had no errors. Added back the code-behind in the ASCX.vb and compiled. Same error.'fieldName' is not a member of They fieldName can be anything. Textboxes, hiddens, checkboxes, etc.
what am I doing wrong? I have spent hours on this I am hoping I am just missing something simple.

I am having a problem regarding to Importing file from excel to listview. Actually my problem is that my program will let the user define what database he/she want. I know already how to load on my listview from .txt, access, ms sqlserver, but my problem is the user want to open from excel file. Base from his data, the columns contained Contact, address, age,name and only in sheet1. My problem now is that the user want to call his/her excel act like a database. The tablename will be Sheet1 and if he/she want to display the age and name column he/she can view by calling the its columnname. The columname will act as a fieldname. How can I do this upon loading all of this to listview. I have here an example on how i load data from .txt(csv) format but i need an excel on how to load data coming from excel.[code]...

I am trying to write a query on an .aspx webpage connected to an .aspx.vb file to access some parts information on my mysql server. Everything works fine except for one poorly named file, which keeps breaking the query. The fields name (with the table name in front) is
invf12.PRICEE(1STU_M)
Those brackets seem to be the problem. I have tried putting single quotes around them, as in
invf12.' PRICEE(1STU_M)',
I can't do anything about the fieldname. The query in total looks like this:
Protected Sub LookupPart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LookupPart.Click
Dim strSQL As String = "SELECT invf12.ITEMCODE as Part, invf02.DESCRIPTION as Description, " + _
"SUM(invf12.QUANTITYONHAND - invf12.QUANTITYRESERVED) as Available, invf12.PRICEE(1STU_M) as Price" + vbCrLf + _
"FROM invf12, invf02" + vbCrLf + _

but then what? combobox1.fill ("EmployeesTable") ?

Select Case currentNodeName
Case "string1","string2","string3","stringEtc"
Case Else
[Code]....
The above is a code snippet... of course I've already made my declarations earlier in the code. My issue is I get the error " 'Select Case' must end with a matching 'End Select'." It looks to me like VB is not liking my If statement with the "Next For" in the middle. I'm sure this is a basic syntax issue.

I have been cracking my head for hours on what I thought to be simple SQL SELECT command. I searched every where and read all questions related to mine. I tried an SQL Command Builder, and even read and applied complete series of SQL tutorials and manuals to try to build it from scratch understanding it (which is very important for me, regarding next commands I'll eventually have to build...).
But now I'm just stuck with the results I want, but on separates SELECT commands which I seem to be unable to get together !Here is my case : 3 tables, first linked to the second with a common id, second linked to the third with another common id, but no common id from the first to the third. Let's say :
Table A : id, name
Table B : id, idA, amount
Table C : id, idB, amount
Several names in Table A. Several amounts in Table B. Several amounts in Table C. Result wanted : each A.id and A.name, with the corresponding SUM of B.amount, and with the corresponding SUM of C.amount. Let's say :
A.id
A.name
SUM(B.amount) WHERE B.idA = A.id
SUM(C.amount) WHERE C.idB = B.id for each B which B.idA = A.id
It's okay for "the first three columns", and "the first two columns and the fourth", both with a WHERE clause and/or a LEFT JOIN. But I can't achieve cumulating all fourth columns together without messing everything !One could say "it's easy, just put an idA column in Table C" ! Should be easier, sure. But is it really necessary ? Running VB 2010 and MS SQL Server?
