DB/Reporting :: Use SQL Statement To Return Value To Function

May 1, 2012

I have 2 functions that need to work together.1 function is to generate a chart number. The other function is to search via SQL to see if the chart number exists. if the chart number doesn't exist then i need function 2 to return a boolean value so function one can generate a new chart number example code: [code] Now i know that i am probably using the incorrect sql statement, my main issue is that i dont know how return available back to the function.

VS 2008 Return Statement In Function?

Apr 12, 2010

1. I would like to know why a Return statement is needed in the function in the first set of code, but not in the second(even though it still works with the Return statement). The functions are called the same way, so what is the difference?2. Why in the second code, the variable FutureValue is allowed to have the same name as the function? But when, in the first set of code, I try to rename the variable "discountPercent1"(in the function) to the function name "SetDiscountPercent", VB 2008 Epress gives the error message "The name conflicts with an existing symbol with the same name"?

Public Class frmInvoiceTotal
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

Return An (Anonymous Type With A Function) From A Function?

Mar 3, 2011

Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:

[code]...

I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:

copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)

If Statement Doesn't Return

Mar 22, 2012

Am I just being blind or does this If statement genuinely not do what it's meant to.[code]This displays the message box even though textSample is one of the letters. In my eyes that If statement should see that textSample is one of those letters and skip it, whereas if it was Z it would "Not" be equal to any of those and would therefore show the message box.

Can't Return Datatable Within A Try Statement

Mar 18, 2012

I have the following piece of code that I am using to try and rip a csv file and turn it into a datatable. My problem is that the debugger never makes it to the return statement. Everything is appending to the datatable correctly, so I know that part works. Any idea's on what I can do to trouble shoot this further. Also, if you know of a simpler way to turn a import a csv file to a datatable I'd be very interested in learning about it.[code]..

It say that the Object reference is not set to an instance of an object. What's weird though is that it works through the whole data table fine. Could it be that the while loop is not terminating at the end of the file?

DB/Reporting :: Why Cannot Return The Table From Access

Mar 9, 2011

There are two combo boxes taking user's inputs to return a record in an Access Database satisfying the requirements. This procedure is controlled by a button. However, when it reads "da.Fill(dt, "NETP_ParaList")". It reports error saying that "ArgumentException was unhandled; Object is not an ADODB.RecordSet or an ADODB.Record. Parameter name: adodb" I have no idea what this talking about.

DB/Reporting :: SQLite Insert Return Unique ID

Feb 3, 2010

I am using SQLite and what I am doing is passing a simple SQL statement to the database, however I want to also return the Unique ID that the insert statement has been entered to, however I am not sure how to do this within a single SQL statement.

My code is below:
Dim mySQL As String = "INSERT INTO DisplaySetFolderTbl (parentID, folderName) VALUES ('" & selNode.Tag & "','" & Trim(Me.txtName.Text) & "')"
Dim cmd As New SQLiteCommand(mySQL, MISData.Instance.dbDRV)
Try
cmd.ExecuteNonQuery()
Catch
Exit Sub
End Try
MISData.Instance.dbDRV is the connection string

.net - Will Sqldatareader With Using Statement Ever Return An Output Parameter

Aug 21, 2011

Here's a simple code snippet of a larger function as an example.

Using conn as New SqlConnection("conn string")
Using find as new SqlCommand("ExampleProc",conn)
Dim rParam as new SqlParameter("@RESULT",SqlDbType.Int)

[code]....

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.

Return Inside Of Using Statement, Will Dispose Be Called.

Jul 27, 2012

I know that if i have a using block like

using myresource

return 0

end using



myresource will be disposed .

But if my using block is

using myresource

return myresource

end using



Will myresource be disposed?

I am wondering if a similar using block is causing memory lead in the app.

Will Statements Or Expressions Execute After A Return Statement

Jan 29, 2010

I was rooting around in one of our company apps which is done in VB.net. I'm not familiar with VB.net (I do stuff in C#) so I'm asking this question: Does the code after the clean up comment execute? [code]It is my understanding once you say return, you give the calling function control again.

DB/Reporting :: Get Data From Oracle And Sql In One Sql Statement

Nov 6, 2009

I will try and explain my problem as simply as I can

I have an Oracle database (external app) that contains a number of tables that I need to get data from, however I also have an SQL database that contains a number of tables that my app is using.

e.g. Oracle Table name PD_112

Structure:

CODE:

What I want to do is get all the data from the Oracle table to display in a list control however I want the values in the DISP_ID column of the Oracle table to be change to the corrosponding DESC values from the DispTbl e.g. 5 from the Oracle table would display Piping instead of 5.

I know how to do this if both the tables where in one database system e.g. Oracle or SQL, however I am not sure the best why to do this when the tables are in 2 different data sources.

Below is the code for doing this in the same datasource:

Code:

I am using VB.Net 2005, just for info

DB/Reporting :: INSERT INTO Statement Working But Not Saving?

May 19, 2012

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.

vb.net code below

Code:
Try
Dim cmd As New SqlCommand
cmd.Connection = con
