Efficiency: Inline TSQL V. Subcalls
Apr 6, 2000
Hello,
I regularly create stored procedures and use them like functions within other stored procedures.
I've never had any difficulty but then I never ran any metrics on it.
Does anyone know if there is an efficiency difference between that approach and just doing an inline query? How much of a difference is it? minimal? impractically large?
For example, if I define an sp like:
create proc isValidUser @userID int , @result int OUTPUT as
if exists(select * from user where userid = @userID)
set @result = 1

I want to select one field from a table,but it should on some conditionswhich refer to 5 table ,such as A.FILED1=B.FIELD1 AND B.FIELD2=C.FIELD3 AND....Should I use case "select sum(a.amount) from a,b,c,... wherea.field1=b.field1 and b.field2=c.field2 and ..." or "select sum(a.amount)from select b.field1 from select c.field2 from...."?And which case is moreefficiency?thanks!我想计算一个表中的某个字段的和，但此记录需在从多个 表中查询此记录是否满足特定的条件。那么我是用select ..from ...where ..and ..and..and ..and ..还是用select ..fromselect ..from select ..from ......？请问是哪一个效率高？谢谢！

Hello,
I would like to know if there is any sort of improvement when using Inline SQL vs Stored Procedures as far as the execution plans are concerned when they are used in SSIS packages. I happened to create a SSIS package which calls Stored Procedures but internally they are using Linked Servers to get the data required. At this point they want to know what will be benefit that can be achieved when Inline SQL is used.
I would appreciate if anybody can give their thoughts or provide some informative articles like pros and cons.
Thanks in advance.

Hello,I am looking at optimizing site searching on a web application. I have two thoughts on the idea:1. create views with fulltext indexes combining records from multiple tables.2. create a table with an xml column and primary index. I understand the xml column type has the overhead of a BLOB under the hood, but that a primary xml index can "shred" the contents and improve parsing. I also read the xml column is actually searched as a tree, providing some variant of log(n) run time. Does anyone know of good literate on this subject, the more big O notation, runtime analysis types of posts the better.Thanks

Hi guys,
Since the project that i'm developing is rapidly increasing, the pages seems to be getting slower everytime you view it. I would like to ask if code below would be efficient enough for several simultaneous request of data or if you have any other suggestions, you are welcome to add:

Hey,I am developing a website which will be used by a large number of people so I am concerned about efficiency.Sorry for the three posts but anyone with any info would be appreciated.The database has the following tables: FACILITY-----MEETING ---- | | USERS---- -------- MEETING_INVITE -------- REMINDER | | ---------CONTACTS-------When the user logs in I use there username to access the rest of the tables. I get all of the users information out of the database in one go and store it in a dataset.So when a user accesses there meetings page, I pass the dataset to that page with a server transfer.Question 1 > Is it more efficient to open the database once and access all the information and pass the information to seperate tables or is it more efficient to access the database on the individual pages and thus not passing of information.---------------------------------------------------------------------------------------------------------------In order to access the information I use 6 Select statements in a rowHere is an example of my select statments: SELECT * FROM USERS WHERE email = textbox_emailSELECT FACILITY.* FROM FACILITY, USERS WHERE FACILITY.email = USERS.email AND USERS.email = textbox_emailBy the time I get to the REMINDER table I am combining all the tables and my query is eight lines long.Question 2 > Is there a way of combining the results of a previous select to access information?---------------------------------------------------------------------------------------------------------------Question 3 > What do you think of my table design? The lines represent one to many relationships. If you can give me any tips on databases please do.Thanks for your time,Padraic

Hello all,I am developing a website which may be used by a large number of people in the future and I am concerned about performance.
Is it better to have one table with 50, 000 rows or 5,000 tables with 10 rows each?
Is there a way to divide a table in two if the table reaches a certain size?
Is there a limit on the size of tables?
Is there a limit on the number of tables?
Is it possible to create tables from vb.net?
Is it possible to program checks into sql server? For example, could I delete data that has passed a certain date or send an automated email when a time is reached?
Thanks for your time,Padraic

Hey people
I'd be really grateful if someone can help me with this. Could someone explain the following:
If the following code is executed, it runs instantly:
declare @SellItemID numeric (8,0)
select @SellItemID = 5296979
SELECT distinct s.sell_itm_id
FROM stor_sell_itm s
WHERE (s.sell_itm_id = @SellItemID )
However, if I use this WHERE clause instead -
WHERE (@SellItemID = 0 OR s.sell_itm_id = @SellItemID)
- it takes 70 micro seconds. When I join a few more tables into the statement, the difference is 4 seconds!
This is an example of a technique I'm using in loads of places - I only want the statement to return all records if the filter is zero, otherwise the matching record only. I think that by using checking the value of the variable in the WHERE clause, a table scan is used instead of an index. This seems nonsensical since the variable is effectively a constant. Wrapping the entire select statement with an IF or CASE works, but when I've got 10 filters I'd have to 100 select statements.
I DON'T GET IT!! There must be a simple answer, HELP!!
Jo
PS this problem seems to occur both in 6.5 and 7.0

Hi All,
I tried my luck in the Access forum and I've search the web and MSDN for an answer with little luck.
Simply, is it better to update a table via an UPDATE query or Recordset manipulation?
I have read that if you were to update 10,000 records an UPDATE query is more efficient (obviously), but does that transend down to say 1 - 10 updates?
i.e. There are six unique updates I want to make to 6 different rows. Should I code the backend VB to execute 6 different queries or seek and update a recordset?
It's a MS Access XP app with ADO 2.8.
My gut feeling on this is that making 6 update queries is more efficient, both with system resources and record-locking issues; I'd just like another opinion on the matter.
I appreciate your help!
Thanks,
Warren

I would like to use MVJ's formula for creating a date table.
I would like to use it with our main ERP database. However, I am reluctant to make changes to it because I fear that at some point when we upgrade that software and it's database that the upgrade program will delete my table.
So, here is my question. Performance wise, does it matter whether I add the date table to our ERP database or if I create another database (on the same server) for the custom date table? Does linking between databases take substantially longer than linking within the same database?

Hi,
okay so I'm refactoring some code at the moment. At the moment, I'm working on a search screen. This search screen lets the user enter a number of criterias, I'm working on drags data from a view and then programmatically filters it according to the search filters.
This is obviously inefficent and non-scalable as the view drags out every entry and returns to the data layer, which then filters it.
I'm wondering what the best way to refactor this? i'm thinking the best way is to tell the db what to filter on, so it'll only drag out the right amount of data.
Therefore, should I keep the view? Is there any way of entering parameters into views or am i going to need to change this into a stored proc?

Greetings all,
I need to determine a hierarchy from a table with EmpID's and SupID's. Basically, the President doesn't have a SupID so it will be null. I need to determine programatically the hierarchy to keep it simple.
I have code that works and I was hoping for advice on optimizing it 'cuz it uses a cursor.
Also, It only deals with less than 300 records.
Code Block
CREATE TABLE Employee(fName varchar(30), EmpID int, SupID int)
INSERT INTO Employee SELECT 'Adam', 1, 4
INSERT INTO Employee SELECT 'Joe', 2, 4
INSERT INTO Employee SELECT 'John', 3, 4
INSERT INTO Employee SELECT 'Frank', 4, 10
INSERT INTO Employee SELECT 'Jane', 5, 10
INSERT INTO Employee SELECT 'Kristy', 6, 10
INSERT INTO Employee SELECT 'Angie', 10, 11
INSERT INTO Employee SELECT 'Ron', 11, NULL
--=====================================================================================
-- CODE
--=====================================================================================
CREATE TABLE #temp(Hierarchy int, myName varchar(30), SupID int, EmpID int)
INSERT INTO #temp SELECT 1, fName, SupID, EmpID FROM Employee WHERE SupID IS NULL
--NULL SupID means that they are at the top most branch
DECLARE @Counter int --Counter is used to increment
SET @Counter = 1
DECLARE MY_CURSOR Cursor
FOR
SELECT SupID, EmpID, fName
FROM Employee
ORDER BY SupID --ORDER BY SupID to bring NULLs to top
Open My_Cursor
DECLARE @EmpID int, @SupID int, @Name varchar(30)
FETCH NEXT FROM MY_Cursor INTO @EmpID, @SupID, @Name
WHILE (@@FETCH_STATUS = 0)
BEGIN
SET @Counter = (SELECT MAX(Hierarchy) FROM #temp) + 1 --Get the highest hierarchy ID and increment by 1
INSERT INTO #temp
SELECT @Counter, fName, SupID, EmpID
FROM Employee
WHERE SupID IN (SELECT EmpID FROM #temp WHERE EmpID = @SupID)
FETCH NEXT FROM MY_CURSOR INTO @EmpID, @SupID, @Name
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR
SELECT * FROM #temp
DROP TABLE #temp
Thanks in advance,
Adam

Howdy folks!
I've got a database that needs to run 24/7. I'm looking into maintanence options and wanted to run the following by y'all:
Ok, I've read the MSDN "Maintaining databases" article and noticed the following statement about autoshrinking: "This technique uses almost no processor time and memory". I also searched these forums and found that many users say autoshrinking heavily lags down sql transfers. So who's right? And if it does lag transfers, by how much?
Another question I have about autoshrink is fragmentation. It would seem to me that over time solely depending on autoshrink would cripple a server in terms of fragmentation; is this the case?
Also, does autoshrink (or manual shrinking or compacting) update the statistics?
Final question!!! I'm programming in native c++, is there a way for me to run commands such as "DBCC SHRINKDATABASE" in native OLE DB code?
Thanks!

Hi, I'm trying to get MSSQL to choose which row to display from a result from a query, but it seems to need an 'IF' or something similar.
My query asks the database to pick out all rows that meet critera X, but sometimes (quite correctly) some of the rows created by query X are duplicates. (A data overlap nothing wrong with the query)
I want to be able to get the query to decide which one of these duplicates to display. There is a unique element.
Example Below
|ID | SYSNAME |DATE |ACTIVE
---------------------------------------------
1 | PC1 | 10/3/7 | 1
2 | PC1 | 10/3/7 | 0
3 | PC2 | 10/3/7 | 1
ID 1 + 2 is the duplicate.
In my example I want to remove ID 1 from the result, I can't use the 'active' column as this will remove ID3 fro the result.
I want the query to recognise the duplicate based on the sysname, then choose to display the result with 0 in it.
Does anyone have a clue what I'm talking about? I'm loosing the plot.

I'm working on a "comments" section for our application suite.
My thoughts are to have 1 Comments table, which is then linked to a comment Log table.
For each section: Item, Group, Section, User, Package (these can all have comments on them) I will link them to the comments in a many to many relationship.
Example:
Comments Table-CommentID-UserID
UserComments-UserID-CommentID
User_Table-UserID....
Would doing that be more efficient than having 1 seperate comments table, and log table for each area I want to have comments?

Hi all.
I am new to reporting services and I am having an efficiency problem when loading my report.
I would like to know how Reporting Services handles its datasets.
1: Lets say I have 3 parameters. All set to retrieve data from the same dataset. Does reporting services execute the Query 3 times to get the results for each parameter ? If so, is there a way around this ? I am having a great performance hit with this if it is the case.
2: I am also having an issue with a data processing extensions, when my multi-valued parameter reads the fields from the dataset.. it inserts duplicates and not distinct values, Do i need to explicitly select distinct values in the data processing extension or should Reporting Services automatically do this ?
Any help is greatly appreciated.
Regards,
Neil

I have to write a query for printing multiple barcodes, depending on the quantity of items that came in the store, based on the order number.
DECLARE @num INT
SELECT BarCodes.BarCode, BarCodes.ArticleID, ArticlesTrafic.DocumentID, ArticlesTrafic.TrafficQuantity
FROM BarCodes INNER JOIN
Articles ON BarCodes.ArticleID = Articles.ArticleID INNER JOIN
getAutoNumberTable(@num) ON @num=ArticlesTrafic.TrafficQuantity
WHERE (ArticlesTrafic.DocumentID = @Param2)
The thing i would like to do, is somehow assign a value to @num and pass it to the getAutoNumberTable stored procedure, which generates a table of consequtive numbers, so that each record is displayed multiple times. Is it even possible to do it without using temp tables and loops?

This feels like a question that has been asked 1000 times...I'm just not having much luck finding an answer.
I want to bold a single word in a Textbox on a RS2005 report. Is there a way to do this? The text is always bold. Like this:

I have a serialized XML that I got from a dataset. In my 'Data Flow Task', I bind the 'XML Source' source to this XML file. Since the XML file is having the schema along with it, I check the 'Use Inline schema' option. However, when I put a dataviewer to see the rows getting sent to the destination, I see that no rows are getting transfered. As you will see from the XML file I am trying to use, I do have one row to transfer.
I tried kepping the schema file and the content file separate and that worked. I am not sure if there are any inherent issues I need to take care of, when using inline schemas to transfer data. I have the SP2 for SQL 2005 installed.
Here is the XML file content:
<?xml version="1.0"?>
<DataSet>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="NewDataSet">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="Table1">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" name="LastName" type="xs:string" />
<xs:element minOccurs="0" name="FirstName" type="xs:string" />
<xs:element minOccurs="0" name="Descr" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
<NewDataSet>
<Table1>
<LastName>Agrawal</LastName>
<FirstName>Sumeet</FirstName>
<Descr>Consultant 1</Descr>
</Table1>
</NewDataSet>
</DataSet>
Thanks,
Sumeet

I have two questions regarding in-line bar charts...
First, I put the text as data labels and check 'Auto' for positioning, most of the time the text is written to the right of the bar (which is what I want). However, there is one case that if the space to the right of the bar is not enough for the text, it starts writting on the bar itself.... is there a way I could set it so that the text only appears when there is enough space to the right, so that text never appears on any bars?
Secondly, is there a way I could put hyperlinks on the text?
Thanks again,
Steven
