I once had a DBA tell me the ancient wisdom of the different ways of searching through lists and the performance impact of each type. Does anyone know this secret?
I think the best performance was SELECT * FROM temp WHERE temp.acctid IN (1123,1234,1235)
The worst performance I think would have been correlated subqueries. Then I can't remember where temp tables and embedded queries ranked.
Thanks

View 1 Replies View RelatedHi again, all...here I am again, trying to work on my CloseIndex thang again...Same subject, different tack...
Basically, I have two tables...for the sake of simplicity, let me define them as:
PortfolioIndex
PortfolioID int
CreateDate smalldatetime
CloseIndex float
PortfolioPerformance
PortfolioID int
CreateDate smalldatetime
PrevDate smalldatetime
DailyPerChg float
UPDATE PortfolioIndex
SET CloseIndex = CASE
WHEN PPI.CloseIndex IS NULL THEN 100.00
ELSE (PPI.CloseIndex + (PPI.CloseIndex * PP.DailyPerChg / 100))
END
FROM PortfolioIndex AS P INNER JOIN PortfolioIndex AS PPI on (P.PortfolioID = PPI.PortfolioID), PortfolioPerformance AS PP
WHERE (P.PortfolioID = PP.PortfolioID) AND
((P.CreateDate = PP.CreateDate) AND
(P.CreateDate = @CreateDate) AND
(PPI.CreateDate = PP.PrevDate))
What I am trying to do is...get the previous day's portfolioIndex row's CloseIndex and create a new one for today's row.
As ugly as it is, it works when I execute it in the SQL Query Analyzer, but when I try to create the stored procedure, the syntax check complains that the PortfolioIndex reference at the UPDATE... part is AMBIGUOUS...yet when I define it in the SP as P.PortfolioIndex, it fails at run time saying there is no object named P.PortfolioIndex (well, of course there isn't!).
How can I make this work (and if possible, make it prettier too! *L* ;) )
I'm want to be able to choose(including multiple selections) names from a drop down list that are fetched from the database(from table "Employees") and add them to table "Biotechnology".
Employees(ID,FirstName,LastName)
Biotechnology(ID,EmployeeID)
**assuming that EmployeeID in "Biotechnology" is the ID from "Employees" table
Example: We add Employees.ID(23, 33) to Biotechnology.EmployeeID
would be
Biotechnology:
[ID] [EmployeeID]
01 - 23
02 - 33

I am glad to announce that there is now a version of my article "Arrays andLists in SQL Server" for SQL 2005 available on my web site.THe URL for the article ishttp://www.sommarskog.se/arrays-in-sql-2005.html. If you are curious aboutthe performance numbers they are in an appendix athttp://www.sommarskog.se/arrays-in-sql-perftest.html.The old version of the aritlce remains, as the new article covers SQL 2005only. The old version is now athttp://www.sommarskog.se/arrays-in-sql-2000.html.The old URL, http://www.sommarskog.se/arrays-in-sql.html leads to a pagethat links to both articles.And the reason that there are two articles is simply that SQL 2005 addsso many new features: nvarchar(MAX), the CLR, the xml data type, CTE thatall can be used in the realm of arrays and lists.--Erland Sommarskog, SQL Server MVP, Join Bytes!Books Online for SQL Server 2005 athttp://www.microsoft.com/technet/pr...oads/books.mspxBooks Online for SQL Server 2000 athttp://www.microsoft.com/sql/prodin...ions/books.mspx
View 1 Replies View RelatedIs there a way to use PreparedStatements (or bind variables) with SQLstatements that have a variable number of arguments. For example, Ihave an array of IDs for employees of a certain type and I want tohave a PreparedStatement retrieve all of them in a single SQL call.SELECT FROM employees WHERE employee_type = ? employee_id in(?,?,?,...,?)It seems at least in Java that PreparedStatements can only take afixed number of arguments?PreparedStatement pstmt = con.prepareStatement("SELECT FROMemployees WHERE employee_type = ?

I'm trying to get data from WSS lists by web services. I think there are two ways:
- using SSIS standard components (Web Service Task) and
- creating a custom source adapter.
My problem with the Web Service Task is, that the WSS method GetListItems has some non-standard parameters (see part from wsdl-file below). Thus, after selecting the method in the editor an clicking on "Ok", I get the error message "The selected Web method contains unsupported arguments". I think the problem is the missing type-attribute.
<s:element name="GetListItems">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="listName" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="viewName" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="query">
<s:complexType mixed="true">
<s:sequence>
<s:any />
</s:sequence>
</s:complexType>
</s:element>

My question: Is there a way to extend the Task to handle such parameters?

I would like to display a couple of records horizontally via a table or list, but don't think this is possible. Am I right? The given recordset should only have two records and the formatting would be much better if they were displayed left to right rather than one on top of the other. Is this just not possible with SSRS? Thanks,

Hello,
I`ve created a table in a list that is grouped by years. Result is a Report, that consists of several years (List grouped by years, each containing the table with the data of the year).
Now I want to aggregate some numbers of the table on each page (year) of the list.
The sum()-function - doesn't matter which scpoe I use - always aggregates only the values of the actual list (Year), not considering the years before.
Can anyone help?
Thanks a lot -

I was under the impression that Management Studio wouldn't list any databases that a user doesn't have access to. But if I create a new user and give them db_owner permissions to just one database, if they log into Management Studio, they are able to see all databases listed. They don't have access to do anything further, but they can still see the list which I thought was handled better in 2005.

I want to display a phone directory by department.
I created a list and told it to group on department and then I put a table in the list that had PhoneNo, EmployeeName as the columns.
Now the list works in that it seperates that table out by department (so 5 departments means 5 instances of the table with a text box above the table but inside the list with DepartmentName.Value).
The problem though is that text box only appears once for each table, the first time the table is generated. I can't get the department name to display at the start of each page.
Do I need another sublist or something, how can I get the department name textbox to appear at the start of each page for my list?
So what I have is:
DEPARTMENT NAME: Sales
---(table starts here)
.............5555...Smith
.............lots more names.......
- - - - - - - - - - - - - - - PAGE BREAK - - - - - - - - - -
---(table continues on from last page...)
.............4444...Johnson
.............3246...Benson
---(table ends here)
------------------------------------new iteration of this, so the next department is IT and this all repeats again
What I want to get is:
DEPARTMENT NAME: Sales
---(table starts here)
.............5555...Smith
.............lots more names.......
- - - - - - - - - - - - - - - PAGE BREAK - - - - - - - - - -
DEPARTMENT NAME: Sales (this is repeated as it is the start of a new page, in a perfect world I'd be able to even say "Continued..." after the department name on all pages that were not the first page it appeared)
---(table continues on from last page...)
.............4444...Johnson
.............3246...Benson
---(table ends here)
------------------------------------new iteration of this, so the next department is IT and this all repeats again with department name at the start of each and every page
I have a large report which profiles a customer and produces many pages consisting of sales records, support calls and emails, etc etc.

I'm writing a Data Processing Extension for SSRS 2005 that allows you to use a WSS 3.0 List as a dataset.
This works for one list per dataset. Now I am trying to extend the extension to allow multiple lists in a dataset because I want to join lists on a common field (INNER JOIN). The problem is that I can only return one DataTable to the Report Server with the DataReader. Does anyone know if it is possible to return multiple DataTables (without the join)?
I'm a student, working on this project. I know Visual Basic.net but only started last month with Data.

Hi,
I plan to implement UDT for division methods.
The following fragment TSQL with zero check:
DECLARE @a int, @b int
SELECT
CASE WHEN @b = 0 THEN NULL
ELSE @a / @b
END
Clr UDT may look like this and script will be shorter.
DECLARE @a int, @b int
SELECT @a Type :: divide(@b)
Is that better to use UDT ?
Anyone have try this before?

Hi
Will somebody please explain how to combine asp.net dropdown lists to write
a SQL database select query. I am using VWdeveloper and C Sharp.
For example, say I have 3 dropdownlists on my webpage as below,
List 1, Cities, London, Rome, Barcelona etc
List 2, Restaurants by Type, Italian, chinese, Indian etc
List 3, Number of tables/ seats 10-20, 20- 40, 50 -100
I want someone to be able to search for a restaurant by selecting an item from each dropdownlist
such as, "Barcelona" "Italian" "50-100"
This search query would return all the Italian restaurants in Barcelona with 50-100 tables/seats.
I would also like the select query to work even if one of the dropdownlists items is not selected.
Hope somebody can clear this up?
Also would sql injection attacks be a threat by doing it this way?
Thanks all
I'm new (very new) to asp.net and now at 3am after maybe 12 straight hours of trying to go through examples and understand the syntax, I have a somewhat working program... basically a query parameters screen that upon a click generates a report. The query parameter screen basically is a HTML form with a procedure that puts the field values into session variables. The report uses <asp:sessionparameters> in the sqldatasource to apply aforementioned session variables to filter the SELECT statement's results. They are then displayed using the gridview control. It actually works!
Now I'm trying to figure out: if I need/want my users to be able to enter comma-separated list of values into the HTML form field and somehow get these into the SELECT statement's WHERE clause, is there a way to do this? I'm not very experienced with asp nor sql server and have been struggling with this new challenge. I really could use pointers as to whether there's an easy way to handle this. In other languages in the past I would have had to parse the comma-separated list and use those to construct my SELECT statement programmatically. I get the impression that with all this ASP.NET fanciness, there has to be a better way?
If it matters, I'm using ASP.NET 2.0 with SQL Server 2005 Express and Visual Studio Web 2005 Express.
Thanks in advance for any replies, they would be GREATLY appreciated :)
I have gridview bound with SqlDataSource control. One of the grid columns is a dropdown list which is populated programatically, (the gridview has template column with edittemplate field with dropdown list), dropdown Value contains of course collection of IDs.Please tell me how to declare UpdateCommand which will update the row with the dropdown list. The problem is with parameter regarding the column with dropdown list. When i declare this parameter and bind it to SelectedValue property of the dropdownlist from edittemplate tag - it doesnt work, because datasource control cannot see this dropdown list. So, how am i supposed to declare the ID of the row being updated in <updateParameters>? Thanks in advance!
