Need Help Constructing A View!
Apr 4, 2006
Not sure where to post this question so if you can answer this or have a better forum suggestion, please advise:
I have two tables.
Table USACITY has 100 cities with Latitude and Longitude data (Fields=CITY,CITYLAT,CITYLONG). T
Table USAFAC has 12000 facilities with Latitude and Longitude data (Fields=FAC,FACLAT,FACLONG).
I have an expression that I can use to calculate the distance between any city and facility. The resulting field in the view will be DISTANCE.
Resulting view will include CITY, CITYLAT, CITYLONG, FAC, FACLAT, FACLONG, DISTANCE.
The total possible combinations are 1,200,000 however, the dataset that I am interested in will only include city-facility combinations within 150 miles of each other.
I have built 12 databases in Access that I am now in the process of converting to SQL so I am on a rapid learning curve. Any solutions should include code and instructions on creating the view.
Thanks in advance for any help!

Hi,
I am experimenting to make a datatable in C# code in a page. This table should be a disconected table with Only valid for the present session.
I try the following code:
public partial class Default2 : System.Web.UI.Page
{
DataTable DT = new DataTable("TEST");
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataColumn Col1 = new DataColumn("Col1");
Col1.DataType = typeof(Int32);
Col1.AllowDBNull = false;
DT.Columns.Add(Col1);
DataColumn Col2 = new DataColumn("Col2");
Col2.DataType = typeof(string);
Col2.AllowDBNull = true;
DT.Columns.Add(Col2);
DataColumn Col3 = new DataColumn("Col3");
Col3.DataType = typeof(DateTime);
Col3.AllowDBNull = true;
DT.Columns.Add(Col3);
GridView1.DataSource = DT;
}
}
protected void Button1_Click(object sender, EventArgs e)
{
for (int i = 1; i < 20; i++)
{
DataRow MyRow = DT.NewRow();
MyRow["Col1"] = i;
DT.Rows.Add(MyRow);
}
}
}
For one reason or the other. if I click the button I get the message that Col1 dus not make part of the table TEST. It turns out that there are no columns added to the table. altroug the code in the page load part has been run. I suppose I have to do something with the session state to make my DataTable persistent, but I have no idea what. Can somebody help me out?
Thanks!

Hi,
I need to construct a stored procedure that will accept a set of comma seperated numbers. What I would like to do is something like this
create procedure shopping_cart(@contents as varchar) as
select dvd_title
from movie_dvd
where dvd_detail_id in (@contents)
dvd_detail_id is defined as int in the table.
The problem is if I declare @contents as varchar, the procedure only recognizes the first number and ignores the others. Does anyone know how to get around this?
Thanks
Dan

I have two tables, both with phone numbers and call times.
one is for incoming calls, one for outgoing calls.
I need to find all phone numbers from the incoming calls table where the number of calls exceeds 100 within the last 30 days, where the last call was within the last 15 mins, and where the number does Not exist in the outgoing call table within the last 30 days.
so far I have this...
(call record is the incoming, callout is the outgoin)
I believe this is giving me all records in the call record table that are within the last month, and not in the outgoing call table OR have not ben called within the last month..
SELECT cr.cli,min(cr.starttime)as "first call",max(cr.starttime)as "last call",count(cr.cli) as "number of calls"
FROM callrecord cr
LEFT JOIN callout co
ON cr.cli = co.cli
where (co.cli is null or datediff(dy,co.calltime,getdate())>30 )
and datediff(dy,cr.starttime,getdate())>30
group by cr.cli
order by cr.cli
i need to add in the 15 minute call check, and also only return those with a count of > 100
can anyone assist? i'm getting a headache :D

Hi i have a page in which stock can be allocated, there are two boxes which have a product serial number start range and a product serial number end range, when these boxes are filled the "allocate" button is then clicked and the product will then be allocated the serial numbers.
What i want to happen is that when the start and end ranges have been entered into the text boxes it will fail if any number within the range has already been allocated previously. E.g
Start Range
End Range
So lets say in the start range text box 15 is entered and in the end range 25 is entered, however 18 has already been allocated previously, this will then bring up a message saying please select another range;
I have done the following so far;private void ValidateRange()
{
//String strSql;SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["strConnectionString"]);
String strSql = "SELECT SqlCommand dbCommand4 = new SqlCommand(strSql, conn);
dbCommand4.Parameters.Add("@Start_RangeID", txt_Start_Range.Text);dbCommand4.Parameters.Add("@End_RangeID", txt_End_Range.Text);
dbCommand4.Connection = conn;
conn.Open();SqlDataReader myDataReader = dbCommand4.ExecuteReader();
myDataReader.Read();if (txt_Start_Range.Text == Convert.ToString(myDataReader["Serial_No"]))
{lblRange.Text = "Please enter a different range a portion of the selected values have already been allocated";
//Response.Redirect("Selectedfilm.aspx");
}
else
{Allocate(true);
}
conn.Close();
}
My problem is constructing the select statement, thanks.

Hi! I'm trying to put together some reports for an attorney's office. I'm having trouble constructing this query. What I'm doing is querying for defendants who do not have a particular charge against them.
Here are my tables:
DCase
-------------------------------
VBKey CaseNumber
1 33365
2 66585
etc..
DCharge
-------------------------------
VBKey ChargeNum
1 27
2 19
3 20
3 21
etc..
Since both tables are linked via VBKey, I joined them together and this is where I got stuck.
I tried using HAVING ChargeNum<>21 but it would still return a result b/c VBkey=3 has two charges against him. So, when do my queries, I'm still getting individuals who have multiple charges. I tried doing this with SELECT DISTINCT but it would still give me results from people with 3 or more charges. I'm lost at how to complete this query. Any help will be greatly appreciated! Thank you!

I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?

Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS
SELECT VendorName, InvoiceNumber, InvoiceTotal
From Vendors JOIN Invoices
ON Vendors.VendorID = Invoices.VendorID

Hi guys 'n gals,
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I tried:
CREATE VIEW [qryMyView]
AS
EXEC pr_MyProc
and unfortunately, it does not let this run.
Anybody able to help me out please?
Cheers!

I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.
I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.
If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.

I have this view in SQL server:
CREATE VIEW dbo.vwFeat
AS
SELECT dbo.Lk_Feat.Descr, dbo.Lk_Feat.Price, dbo.Lk_Feat.Code, dbo.SubFeat.SubNmbr
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:
SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application.
Thanks for help

I was looking through our vendors views, searching for something Ineeded for our Datawarehouse and I came across something I do notunderstand: I found a view that lists data when I use it in t-sql,however when I try to use the statement when I modified the view (viaMS SQL Server Management Studio) I can not execute the statement.

A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.
Can anyone explain why?
Thanks

How do I set up a sql statement to use as a view?
I want to use two tables but they are both from different databases.
From the Offices database I want to use a table called Office Code and only the Name column
The other database is called Library and I want to use a table called Requestors and join it to others.
I've set the stored procedure up that I want to use to get most of the data besides the data in the offices database.
Create view GetDataview
select requestors.officeCode, requestors.Fname + ' ' + requestors.Lname as [Name], Titles.title as Title from requestors
join libraryrequest on libraryrequest.requestorid = requestors.requestoridjoin Titles on Titles.Titleid = libraryrequest.Titleidwhere officecode <> 0order by OfficecodeGO How do I add the database offices, table officecodes to this view to use the Name column?
I hope this makes sense

I have a database with a view to another table in another database which I created a form out of. I was wondering when if this rule applies
"Data Entry" property of the form is set to True. The default value for this property is "False" which means that Access opens the form and shows the existing records. However, if set to True, the Data Entry property of the form specifies that the form will only show a blank record.
The reason I am asking is because you cant see the records after you close the form and reopen it again.
