Databases :: Alternative Way Of Writing SQL Statements

Oct 7, 2009

Can anyone come up with any alternative ways of writing the following statements?

SELECT position, AVG(pay)
FROM staff
GROUP BY possition
HAVING count(employeeID)>=2

SELECT name, pay
FROM staff
INNER JOIN division
ON staff.divisionno = division.divisionno
AND location='USA';

SELECT location, SUM(pay+NVL(comm,0)) AS "full"
FROM staff
INNER JOIN division
ON staff.divisionno= division.divisionno
GROUP BY location;

select name, position, pay, divisionname
from staff
inner join staffposition
on pay between losal and hisal
inner join division
on staff.divisionno= division.divisionno
where positiongrade = 32;

create view staff (name, area, zip)
select name, area, sip from stafftab;

Databases :: JOIN Same - Different Table In Different Databases?

Nov 13, 2009

I have a table where two of the columns are named "ItemA" and "ItemB". Both columns consist of numeric itemnumbers such as 1,22,55,195 etc. I often cobine these coumns with some form of JOIN or UNION which I have a feeling is very ineffective from a performance point of view, joining columns from the same table. Anyhow, it makes it hard to work with so I want to take ItemB out of that table.

So, my questions is: Is it better to put ItemB in a different table and do the JOIN/UNION between the tables? Or is it even faster to put ItemA and ItemB in different tables? Both ItemA and ItemB will be quite large.

Databases :: MySQL And Auto Generating Insert,Update - Delete Statements?

May 11, 2010

Before I get too far down the road I just want some advice. I'm building a web app using VWD2008 and MySQL 5. I've got the membership provider stuff working fine and have an odbc connection setup which works "fine". what I've noticed is that when I configure a new sqldatasource (that will be used to provide data to a listview or something) the Advanced -> generate Insert,Update..... option is disabled. I'm assuming its because of the sql syntax difference of the square brackets issue between MS SQL Server and MySQL.

Before I start writing all my own insert and update statements does anyone know if there is a way to get MySQL and VWD to talk the same language, maybe a different connector or something. I'm using mysql-connector-odbc-3.51.15

DataSource Controls :: Join Across Two Databases On (possibly) Different Servers

Feb 12, 2010

I would like to create a gridview where all of the items in one table are listed and a checkbox is checked if that item also shows up in another table. The difficulty comes in the fact that table are not only in different databases, but possibly on different servers.

Is there any way to do this via ASP.NET connection strings, so that it doesn't matter where the databases live? I'd rather use connection strings, because I don't want to hard-code credentials into the queries (OPENROWSET or whatnot).

Prepared Statements With Sql Server 2008?

Mar 8, 2009

I need to do lots of updates/inserts with small data (1k) in one transaction. However I'm thinking that doing 1000 updates is much slower than doing 1 update with 1MB data. The table would have only 2 columns (id, data).

But I don't know how to implement it. Using prepared statements means I would have to do those many small updates and I can't send to sql server an array of data.

Use Databind Records In Inline If Statements?

Now what I want to do is, check a value that I haven't used called "Question_Type" which could be = 1, 2 or 3 depending if it is multiple choice, short answer, etc. I have tried this:

if Eval("Question_type") = 1 then
Response.Write(" <asp:RadioButton runat=""server"">test1</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test2</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test3</asp:RadioButton>")
end if

How To Make If Statements In Databound ListView

Apr 3, 2011

I have a ListView with many advanced controls and html tags. ListView is bound to collection of profiles when first profile in collection is current profile. current profile has few differences from other profiles ie. flash embed, js and some other stuff. I can access inside of my ListView Container.DataIndex property which gives me 0 as first item in index but i'm unable to use inline If statements like so

<% If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>

this is because i must place pound to access databound item but neither this

<%# If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>

How can i make inline If ?

Web Forms :: VB.NET - Import Statements And Base Classes?

Aug 19, 2010

I have a BasePage class that all of my content pages inherit from. In my BasePage, I have many Import Statements. It seems as though they carry over into the derived class as one would expect. However, if you were to try and access code in the client aspx design page, as you would in the code-behind, you run into problems.

For instance, in my BasePage i have a Public Enum named ThemedSites. It's just an enumerator that lists the 5 different themes my site could be skinned as. I, at times, need to do different things in code, and in design, depending on what theme I'm currently in. I have a Public Property named CurrentSite (might have been more appropriate to say CurrentTheme, but that's besides the point). CurrentSite's return type is ThemedSites. So in code, one would say something like:


This works great in any page that inherits the BasePage class. This falters when that very same logic is used in the design page like:


Now, it works if you fully qualify both sides of the condition, but that's not my question. My question is: why isn't the Imported NameSpace in the BasePage recognized in the client-side server tag, as one would think it would be, according to how it IS recognized in the server-side code-behind?

DataSource Controls :: Using Case When In Select Statements Of Sql

Dec 31, 2009

I am filtering the results of a gridview based on selected values from a drop down list. This all works fine except that I'm trying to provide for the case that if no value is selected on the drop down list, the gridview will display all results. So, based on some other posts that I've seen on this forum, I've tried to incorporate a CASE statement in my SelectCommand for the sqldatasource of the gridview.
Here is the code:

<asp:DropDownList ID="ddlBuilding" runat="server" AppendDataBoundItems="True"
AutoPostBack="True" DataSourceID="dsdBuilding" DataTextField="BuildingName"
DataValueField="BuildingName" Height="28px" Width="200px">
<asp:ListItem Selected="True" Value="-1"></asp:ListItem>
<asp:SqlDataSource ID="sdsPO" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT [PONumber], [Employee], [BuildingName], [ClientName], [OrderedBy], [DateOrdered], [VendorName], [DueDate], [DueTime], [DeliverTo], [DeliverToOther], [SpecialInstructions], [Approved] FROM [PO] where [buildingname]
= (CASE WHEN @Building = '-1' THEN [buildingname] ELSE @Building END)">
<asp:controlparameter controlid="ddlBuilding" name="Building" propertyname="SelectedValue" />

This seems like it should work but when I run the website I get the following error when this particular page is loaded:

IErrorInfo.GetDescription failed with E_FAIL(0x80004005).

Can anyone tell me what I'm missing?

If add an item to the enum definition in this case I have to change all the code that uses switches and that kind og enum which, I guess, is a bad approach in terms on maintenance of the application?
