Index On Result Of Function
Apr 27, 2007
I have a table with about 28 million records in it. Each row has an ID (PK), logged (datetime), IP varchar(15)
The data grows at about 14 million records per year. I'm going to be running queries on the table that extract the MONTH or YEAR from the logged column. In Foxpro tables I would have created indexes on YEAR(logged) and MONTH(logged) so my queries would run faster. Is this possible/necessary in SQL Server?

Hi all,
I copied the following code from Microsoft SQL Server 2005 Online (September 2007):
UDF_table.sql:
USE AdventureWorks;
GO
IF OBJECT_ID(N'dbo.ufnGetContactInformation', N'TF') IS NOT NULL
DROP FUNCTION dbo.ufnGetContactInformation;
GO
CREATE FUNCTION dbo.ufnGetContactInformation(@ContactID int)

)
AS

I executed it in my SQL Server Management Studio Express and I got: Commands completed successfully. I do not know where the result is and how to get the result viewed. Please help and advise.

I am trying to code a WHERE xxxx IN ('aaa','bbb','ccc') requirement but it the return values for the IN keyword changes according to another column, thus the need for a CASE function.
WHERE GROUP.GROUP_ID = 2 AND DEPT.DEPT_ID = 'D' AND WORK_TYPE_ID IN ( CASE DEPT_ID WHEN 'D' THEN 'A','B','C' <---- ERROR WHEN 'F' THEN 'C','D ELSE 'A','B','C','D' END )
I kept on getting errors, like
Msg 156, Level 15, State 1, Line 44Incorrect syntax near the keyword 'WHERE'.
which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.

shcInLineTableFN.sql:
USE pubs
GO
CREATE FUNCTION dbo.AuthorsForState(@cState char(2))
RETURNS TABLE
AS
RETURN (SELECT * FROM Authors WHERE state = @cState)
GO
And the "dbo.AuthorsForState" is in the Table-valued Functions, Programmabilty, pubs Database.
I tried to get the result out of the "dbo.AuthorsForState" by executing the following sql script:
shcInlineTableFNresult.sql:
USE pubs
GO
SELECT * FROM shcInLineTableFN
GO
I got the following error message:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'shcInLineTableFN'.
Please help and advise me how to fix the syntax
"SELECT * FROM shcInLineTableFN"
and get the right table shown in the output.
Thanks in advance,

Hi,
Can I take the [index] result from a table and store it in a local var?
For example a table
declare @keyWords(
word varchar(40),
wordLen smallint
)
word len
---- ---
test 4
t 1
e 1
declare @index smallInt = 2
SET @keyWord = SELECT TOP @INDEX word FROM @KeyWords
This obviously is not correct for several reasons (TOP returns multiple results, TOP doesn't work with local var etc)

I created a function that will return
from OpenDataSource('.....') tablename
where ... is fully populated.
However, I can't figure out how to use it?
For example
select functiona (parameter) as data_src
this returns the "from" statement above
I then try to run
select * data_src
So how do I reference the contents of data_src in the select?
Thanks for any help

Hi,
I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute.
This is my function:
ALTER FUNCTION [dbo].[ReturnPickItemValue]
(
-- Add the parameters for the function here
@TypeID int,
@CaseID int
)
RETURNS varchar(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @RTN varchar(max)
IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1
BEGIN
SET @RTN = 'SELECT PickItem I +
CASE D.IsStartDateEstimated
WHEN 0 THEN CAST(StartDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar)
END +
CASE D.IsEndDateEstimated
WHEN 0 THEN CAST(EndDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar)
END
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID
LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND P.CaseID = ' + CAST(@CaseID as varchar)
END
ELSE
BEGIN
SET @RTN=
'SELECT I.PickItem
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND CaseID = ' + CAST(@CaseID as varchar)
END
RETURN @RTN
END
Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.
I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.
Anyone with any ideas?

Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem:
i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.
thanks,

Periodically throughout the day a report is manually pulled from a SQL Server database. Is their a way w/o me adding a field to the database to have the result set return the "new" results? For example, lets say this is our DDL
Create Table OneTwoThree
(
id int
,date11 datetime
,firefly varchar(10)
)
Insert Into OneTwoThree Values (1, '08/03/2015 18:43:32.012', 'Hi'), (2, '08/03/2015 18:44:11.011', 'No'),
(3, '08/03/2015 19:36:33.011', 'Second'), (4, '08/03/2015 19:37:33.011', 'Alpha')
Prior I could use this syntax, but that was only with needing to generate 1 result set.
Select id, convert(varchar(10), date11, 101) As [Date], firefly from onetwothree
where CONVERT(varchar(10), date11, 101) < CONVERT(varchar(10), GetDate(), 101)
Looking at my datetime values, let's say the 1st was generated at 18:45, obviously the 1st two records in the table would be returned. And let's say a 2nd time I need to generate I want to exclude the 1st two entries as they have already been verified. How can I do such w/o adding a field to the table?

I'm selecting the last latitude & longitude input from my database to put into the Google maps javascript function.
This is how I retrieve the longitude:
<asp:SqlDataSource ID="lon" runat="server" ConnectionString="<%$ ConnectionStrings:LocateThis %>"
SelectCommand= "SELECT @lon= SELECT [lon] lon FROM [location] WHERE time = (SELECT MAX(time) FROM [location] where year < 2008)">
</asp:SqlDataSource>
I wish to input the latitude & longitude into the JAVASCRIPT function (contained in the HTML head before the ASP) something like this:
var map = new GMap2(document.getElementById("map"));var lat = <%=lat%>;var lon = <%=lon%>;var center = new GLatLng(lat,lon);map.setCenter(center, 13);
However, lat & long do not contain the retrieved result but rather a useless System.something string.
How do I assign the retrieved results to these variables and port them over to Javascript as required?
Many thanks!

I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good).
If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something
that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database.
What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps:
<asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource">
<Columns>
<asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" />
<asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" />
<asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" />
<asp:BoundField DataField="density" HeaderText="density" SortExpression="density" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="lbsgalDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT
a.Formulation,
SUM (a.lbs) AS lbs,
SUM ((a.lbs)/(b.density)) AS gal,
( ( SUM (a.lbs) ) / ( SUM ((a.lbs)/(b.density)) ) ) AS density
FROM Formulations a INNER JOIN Materials b
ON a.Material=b.Material WHERE Formulation=@Formulation GROUP BY Formulation">
<selectparameters>
<asp:controlparameter controlid="DropDownList1" name="Formulation" propertyname="SelectedValue" type="String" />
</selectparameters>

Hi guys n gals !
I am having a few problems manipulating the results of my data reader,To gather the data I need my code is:
// database connection SqlConnection dbcon = new SqlConnection(ConfigurationManager.AppSettings["dbcon"]);
// sql statement to select latest news item and get the posters name SqlCommand rs = new SqlCommand("select * from tblnews as news left join tblmembers as members ON news.news_posted_by = members.member_idno order by news.news_idno desc", dbcon); // open connection dbcon.Open();
// execute SqlDataReader dr = rs.ExecuteReader();
// send the data to the repeater repeater_LatestNews.DataSource = dr; repeater_LatestNews.DataBind();
Then I am using: <%#DataBinder.Eval(Container.DataItem, "news_comments")%> in my repeater.What I need to do is pass the "news_comments" item to a function I created which will then write the result. The code for my function is:
// prevent html public string StripHtml(string data) { // grab the data string theData = data;
// replace < with &alt; theData = Regex.Replace(theData, "<", "<"); // return result return theData; }
But I am having problms in doing this,Can anyone point me in the right direction on what I should be doing ???

Basically I want to download the cv's which i get after making a search in the doc's. I am able to get the filename, Path, Filesize by using Index Server Query.Is it anyway possible to extract all the CV Details data by matching the path.I want the cv details from the SQL Server of all the Related Paths at the same time not one at a time. Is it possible.I tried alot but i'm going nowhere. I'm giving my code below. Can anyone help me please.Thank you very much in Advance
string strCatalog = "TestCatalog", strsearchstrings=""; string strQuery=""; strsearchstrings = txtsearch.Text;

I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures.
Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example:
DataUserID, StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1...
Or using a table-valued function to return a temp table as the result.
I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC.
Tables I have are structured as follows:
SHOWS
showID
showTitle
SHOWACCESS
showID
remoteID
VIDEOS
videoDate
showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle,
(SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID)
FROM shows, showAccess
WHERE shows.showID = showAccess.showID
AND showAccess.remoteID=21
ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate.
Can anyone shed some light on where I am going wrong?

I'm using a subquery to return a delivery charge line as a column in the result set. I want to see this delivery charge only on the first line of the results for each contract. Code and results are below.
declare @start smalldatetime
declare @end smalldatetime
set @start = '2015-03-22 00:00' -- this should be a Sunday
set @end = '2015-03-28 23:59' -- this should be the following Saturday
select di.dticket [Contract], di.ddate [Delivered], di.item [Fleet_No], di.descr [Description], dd.min_chg [Delivery_Chg], dd.last_invc_date [Delivery_Invoiced],
[code]....
In this example, I only want to see the delivery charge of 125.00 for the first line of contract HU004377. For simplicity I have only shown the lines for 1 contract here, but there would normally be many different contracts with varying numbers of lines, and I only want to see the delivery charge once for each contract.

I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.

Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.
