I am looking for Articles or Examples on implementing a Single Elimination Tournament architecture in SQL Server.
Bracketology, Playoff Bracket, Single Elimination Tournament, whatever you want to call it.
I need the solution to be able to support all sizes of brackets (from 8 - 64 teams and everything in between).
Any "starts in the right direction" would be much appreciated.
Example usage:
To solve Ax=B
|25 5 1| |106.8 |
A = |64 8 1| , B = |177.21|
|144 12 1| |279.21|
exec dbo.gaussianElimination
N'<matrix>
<row values="25,5,1,106.8"/>
<row values="64,8,1,177.21"/>
<row values="144,12,1,279.21"/>
</matrix>', @verbose = 1
Will give this:
inputMatrix
--------------------------------------------------------------------------------
25,5,1,106.8
64,8,1,177.21
144,12,1,279.21
result
--------------------------------------------------------------------------------
x0 = 0.290000
x1 = 19.700000
x2 = 1.050000
testingScenario
--------------------------------------------------------------------------------
set nocount on
declare @x0 float
declare @x1 float
declare @x2 float
set @x0 = 0.290000
set @x1 = 19.700000
set @x2 = 1.050000
select (25 * @x0) + (5 * @x1) + (1 * @x2) --= 106.8
select (64 * @x0) + (8 * @x1) + (1 * @x2) --= 177.21
select (144 * @x0) + (12 * @x1) + (1 * @x2) --= 279.21

We have a procedure that yields a temp table that has duplicate records as follows:
calc_date
minmaxvalue
1/1/2004

1/1/2004

We now want to go thru the resulting table and do the following:
if there is a duplicate date record, delete the duplicate and update the remaining minmaxvalue to be 3
the resulting ds would look like this
calc_date

I have some Partitioned Views and on all queries using a table for the in clause, table elimination isn't happening.
Check Constraint is on the oid column
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( '05231416529481', '06201479586431' )
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE oid IN ( '05231416529481', '06201479586431' ) )
This is checking all tables (headingnames are unique), ive tried this for the last 3 hours on many different tables containing the oid column.
Unless I write the oid as in the above queries it just doesn't work.
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE headingname = 'TestSystem' )

how do i get rid of the brackets without using any function?
i was reading performance tuning. it says its better not to use functions as it slows down the SP.
Hi there,
I am using the following statement but seem to be getting a Syntax Error. I think this is something to do witt the fact that I don't have brackets around the values. However, no matter where I try to put the brackets I seem to get an error!
Any help would be much appreciated!
Thanks,
Jon

I am using Enterprise Manager to create database tables. In the table design view I am trying to create a column called, section. After typing, section, Enterprise Manager automatically puts brackets around the name, ex. [section]. When I view the table by returning all rows the brackets are gone. However, when I go back to desing view the brackets are there. Why is this happening and what affect does it have on my database?
Thanks,

Hi All,I was hoping someone has experienced this before, I'm having troublegoogling this. I'm working with a poorly writtend database that has somefields named as such: MTIC_PROD_VEND[ 1]I do not have the option to rename this field but I do need to retreive datafrom it with SQL. I've tried a suggestion of [MTIC_PROD_VEND[ 1]]] and thatdoesn't seem to work, it may be because the 1 has a space leading it. Doesanyone happen to have any suggestion to try to work around this? Anyassistance would be greatly appreciated. Thanks.Regards,Stephan

I'm trying to run a SELECT statement to get two different values from a field that looks like this:
"Sample text [123], Sample text 2 [345]"
The two values I'm trying to grab has to be after the last comma. So in this case, I need to get
Value 1: 345
Value 2: Sample text 2
Is this possible to do? I can't create functions to accomplish this.
Hi,
I am looking for a function that can remove the brackets and text within them in a given string.
i.e. 'Hello World (text in brackets)' becomes just 'Hello World'
Thanks alot

Any ideas??

I have a problem setting the default value of a column. I am trying to set it to
(CONVERT([float],getdate()+(2),0))
However, SQL Server automatically sets it to
(CONVERT([float],getdate()+(2),(0)))
While it functionally does not change anything, we have a tool which compares the database schema against a pre-existing schema and shows this as an error.I have tried setting the value directly and through scripts but it does not work either way.
Hi,
On x64 versions of Windows server 2003, there is a folder called "Program Files (x86)". The use of parenthesis in this name has caused a few issues so far, particularly with connecting SQL Server 2005 to Oracle using SSIS. After several hours of searching I realized that the parenthesis was causing it, and eventually I found that the best way is to avoid creating such a name while installing the OS itself, by using winnt.sif. This would be better than renaming it and changing registry entries after the installation is done.
I realize this may not be the best question to ask of Microsoft, but why not just call it "Program Filesx86" by default so no special procedure has to be done to get around these issues? The use of parenthesis is likely to cause even more compatibility issues with other software later?
BTW I use Microsoft products regularly and love most of them
I can't understand why I get 2 different results on running with a Bracket I get 'NULL' and without a bracket I get the declared variable value which is 'Noname'
Below is Query 1:
Declare @testvar char(20)
Set @testvar = 'noname'
Select @testvar= pub_name
FROM publishers
WHERE pub_id= '999'
Select @testvar
Out put of this query is 'Noname'
BUT when I type the same query in the following manner I get Null-------Please note that the only difference between this query below is I used brackets and Select in the Select@testvar statement
Declare @testvar char(20)
Set @testvar = 'noname'
Select @testvar=(Select pub_name
FROM publishers
WHERE pub_id= '999')
Select @testvar
I am using a SQL command in ASP.NET to send a query to a an OLAP cube that returns a dynamic set of data that I load into a datatable and then bind to a GridView. I have made my own ITemplate implementaton for displaying and formatting the data, and the following line is causing me problems:
RawValue = DataBinder.Eval(row.DataItem, "[Month].[Month].[MEMBER_CAPTION]")
The error returned is:
Month is neither a DataColumn nor a DataRelation for table
My guess as to what is happening is that it sees the brackets in the field name and stops reading the field name at [Month], when the actual field name is much longer. I know that it knows about the column name because it displays it correctly in the header. Since I am loading this from an OLAP cube the names of my columns vary based on the criteria so I cannot alias the column because I don't know exactly which columns will be displayed. Does anyone know how I might get the DataBinder.Eval function to work with fields that contain square brackets [ and ] ?
If I use the GridView's "auto-generate fields" option it will show the data (and this is the column name) but I lose all control over formatting and the other custom code I'm writing in my ITemplate interface.
Thanks

I did all this in Visual Part without any line of code. But in the code behind , When i select an item from DDL1 i need its ProductName,ProductCost and Also ProductID. It is simple to get first two. But how can i get the ProductID. Is there anyway to get ProductID from SQLDS1.

Hi, is it possible to make an sql query that has an Outer Join but return only one row of results max per id.
For example i have an Articles table, and a PicturesForArticles table.
The Articles table has an id field(aid), a title field(aTitle) and a content field(aContent).
And the PicturesForArticles table has an id field(pid), a PicPath filed and a field linking it to the articles table(aid)
Obviously the PicturesForArticles field stores pictures for the articles, and article can have a multiple number of pictures, or no pictures at all.
So i want to make a query that will return all of the Articles fields and a picture for each article. Even if the article has many pictures i only want to get a single row for each aid(Articles Id), and if there are no pictures for that article the picture fields will be null.
Is there any way to do this, to only return on row of results for each aid?
Thanks
Hi,
I have received a text file in the following format:

Apr2004 Jerry 600 3 1800
--------- Stella 250 2 500
June2005 XXXX 50 5 250
I am exporting this text file in Sql Server database table. After exporting I need to Update the MtnYear field marked as ------- to appropriate year. ie
The MthYear field for Austin, George,Jessy should be updated with Apr2003,
The MthYear field for Stella should be updated with Apr2004
iiily, for other records. Let me inform if this is possible with the help of a single query or any better way of doing it. The records that i need to update is more than 2 lakhs. I am sorry if u feel this questionis not apropriate.
greetings,i was wondering is it better to have multiple small stored procedures or one large store procedure ???? example : 100 parameters that needs to be inserted or delete ..into/from a table.............is it better to break it up into multiple small store proc or have 1 large store proc....thanks...............
View 3 Replies View RelatedI'm doing a BCP of a large table 37 million rows. On a single CPU server, SQL 7, sp 3, with 512 meg of RAM, this job runs in about 3 hours. On a 8 way server with 4 Gig of RAM, SQL 7 Enterprise, this job runs 12 hours and is only a third done. The single CPU machine is running one RAID 5 set while the 8 way server is running 4 RAID 5 sets with the database spread out over two of them.
Is there something obvious that a single CPU box would run this much faster?
I have a query that returns a certain amount of results. How do I select the last row??? I know I can do the top row by doing (top 1). Basically I need the complete opposite. Please help...

thanks in advance
I've managed to BCP in a single table form a backup DAT file into a database, but it took WAY to long (1 hour+ on a meaty server) and I can't understand why.
The table only had a few rows of data and only had a few small dependancy tables.
The table has a primary key, hence an index so the BCP becomes a logged operation but it still should not take this long.
Here is the BCP command line that I ran :-
bcp <dbname>.dbo.<tablename> in <DAT filename> /U sa /P /S <server> /m 1 /n
Could anyone please shed some light on this. Is there anyway of 'fast' bcp'ing this table into the database overwriting the existing one.
Failing that, is there any way of scripting the transfer of a table from one server to another.
Many thanks.

Hello
I have a sql query that shows the top N numbers of records and also wanted to show the total numbers of this records.
Code:
.
.
.
rs_1.Open "SELECT top 5 msg_id, message, topic_id, last_post_by, id, sdate FROM forum_table",conn,1,3
rs_2.Open "SELECT msg_id, message, topic_id, last_post_by, id, sdate FROM forum_table",conn,1,3 “
Top number to show: <%=rs_1.recordcount%>
Total number of records in database: <%=rs_2.recordcount%>
.
.
.
As you can see, it is only on the same database that I am querying. How do I make a single sql query out of this?
i hav a table of the form
table EMP
(
EMPNAME varchar(50)
)
and the data in the table is
record #1 abc
record #2 abc
record #3 abc

record #6 abc
can i use a single query so as to retain a single record in the table and remove the rest ?
How can I do it by using two subqueries the second of them to be aggregate and have two left joins from the first to the second??
e.g. How can I left join these two queries with the joinfield1,joinfield2 fields??

Select field1, field2, joinfield1,joinfield2 FROM Table1 INNER JOIN Table2 ON Table1.field3 = Table2.field4 where field5=Value
2nd query
Select sum(agfield1) As f1, sum(agfield2) As f2, joinfield1,joinfield2 FROM Table3 INNER JOIN Table4 ON Table3.agfield3 = Table2.agfield4
where agfield5=Value
Group By joinfield1,joinfield2
