Hello all,

Here is an SQL Server 2005 table that lists player scores:





Code Snippet

+--------+--------+----------+
| NAME | POINTS | DATE |
+--------+--------+----------+
| Liz | 7 | 01/04/08 |
| Mark | 20 | 15/03/08 |
| John | 9 | 04/01/08 |
| Liz | 25 | 25/12/07 |
| Liz | 11 | 10/04/08 |
| Mark | 11 | 22/03/08 |
| Patty | 20 | 08/04/08 |
+--------+--------+----------+
I'd like to get, for each player, his/her best performance, including the date. Concretely, my SELECT query should return:

How To Get Last Records In Grouped Query.

Jan 23, 2007

Hi,I want to create query where I could group records by quarters, and getthe last record in each group.e.gCreate Table MyTable(Value [float],date[datetime])Insert into MyTable (value, [date]) values (100, '1-1-2000')Insert into MyTable (value, [date]) values (110, '1-2-2000')Insert into MyTable (value, [date]) values (120, '1-3-2000')Insert into MyTable (value, [date]) values (130, '1-4-2000')Insert into MyTable (value, [date]) values (140, '1-5-2000')Insert into MyTable (value, [date]) values (150, '1-6-2000')Insert into MyTable (value, [date]) values (160, '1-7-2000')Now I would like to get this data grouped by quarter, and get the lastvalue from each quarter. So here I would like to get result like this(120, q1 -2000)(150, q2 -2000)(160, q3 -2000)I know how to create aggregate functions but I have problem with gettingthat last record from each group.*** Sent via Developersdex http://www.developersdex.com ***

160012014-09-02 00:00:00.000CHO1-Z-1280480

What I want to do is update the table so that it populates the PERCENTAGE column on an empref/hrscode/date basis based on the sum of the WRK hours per day and empref.

EG for 2014-09-01 for empref 001 the result would be

Code:
0012014-09-01 00:00:00.000BH1-Z-12837.037180
0012014-09-01 00:00:00.000BH1-Z-99961.728300
0012014-09-01 00:00:00.000CHO1-Z-12837.037180
0012014-09-01 00:00:00.000CHO1-Z-99962.963306
0012014-09-01 00:00:00.000OT11-Z-9991.2356
0012014-09-01 00:00:00.000WRK1-Z-12837.037180
0012014-09-01 00:00:00.000WRK1-Z-99962.963306

IE Sum WRK = 486 so 180 is 37.037 percentage. Each HRSCODE hours total should total 100% (37.037 + 61.728)

I can write a query to do this individually but how can I so this as a query for the full table.

Code:
declare @@total as float
set @@total=(select SUM(hours) from tmsuser.tmswrhrs where hrscode='worked' and empref='001' and '2014-09-01 00:00:00.000'=procdate)
update tmsuser.TMSWRHRS set PTAS1=(Str(((hours/@@TOTAL*100)),12,3)) where empref='001' and '2014-09-01 00:00:00.000'=procdate

SQL Server 2008 :: Grouping By Records That Are Already Grouped?

Jul 27, 2015

I have results from a query that have anywhere from 1-4 results. I have a subid of 1-4 which is grouped by a certain criteria. so for example...

id subid text
1 processing A records
2 1000 records processing
3 importing A records
4 1000 records processed
1 processing B records
2 500 records processing
3 importing B records
4 1000 records processed

Here is what my desired output is giving each group of subids 1-4 an id to be grouped together.

id subid text
1 1 processing A records
1 2 1000 records processing
1 3 importing A records
1 4 1000 records processed
2 1 processing B records
2 2 500 records processing
2 3 importing B records
2 4 1000 records processed

Multiple Tables Grouped By Common Field

Here is my situation. I am building a report that has three different tables each with their own dataset. Example: Opportunities, Leads, Activities. All three of these datasets/tables have a common field - SalesID. I would like the report to show the first SalesID, then all Opportunities for that SalesID in the Opportunities table, followed by all Leads for that SalesID in the Leads table, followed by all Activities for that SalesID in the Activities table, and then rollover to the next SalesID and repeat that for all SalesIDs. Any suggestions on how I could achieve this? Thanks in advance for all help!!!

How To Delete Records With A Field Containing NULL

Feb 9, 2008

Hi,
 All records of a table must be deleted if a field (field1) contains NULL or is made empty by a previous update command.
I did this but it only works when the field is made empty, not when it contains NULL:
dim field1 as string = ""...sql = "delete from mytable WHERE (field1=@field1)"        comd = New SqlCommand(sql, oConnection)        comd.Parameters.AddWithValue("@field1", field1)        comd.ExecuteNonQuery() 
How can i do that?
Thanks

Calculating A Field Value Based On Other Records

May 20, 2008

I have two tables and they have a foreign key relationship.  It will be a 1 to Many realationship. 
Table1- the primary key table has the following columns
ContentID - int identity field
DateAdded- datetime
Table2 - The foreign key table, has the following relevant fields
FK - int foreign key
version - int
When an initial record is added there is a record added to each table.  The ContentID in Table1 will match the FK field in Table2.  Then a user will be able to "edit" the record in Table2, but instead of writing over the record that is already there, a new record will be added to Table2.  I would like to calculate the version field where each time a record is added for the particular ContentID/FK it adds 1 to the last version that was added to that particular ContentID/FK. 
 Does that make sense.  I am trying to implement some type of revision tracking for my CMS that I am building and this is the only way I can come up with because my client is worried that somebody will go in and make incorrect changes to their site and  they want to be able to roll it back to a previous version. 
I would appreciate any ideas.
Thanks,
laura

Select Records That Do Not Duplicate On A Certain Field.

Mar 15, 2004

I am looking for some help in pulling certain people out of a table

This is the basic setup of my table


PK ID NAME MEETING
1 11111 Joe CLASS98
2 22222 Jane CLASS98
3 33333 Bob CLASS98
4 11111 Joe CLASS04
5 22222 Jane CLASS04
6 44444 Sally CLASS04

What I am wanting to do is Select only the people who attended CLASS98 but didn't attend CLASS04

I could just remove the CLASS04 people by sorting if I could just return the rows that do not duplicate the ID and meeting is either CLASS04 or CLASS98

Either way would get me to my goal.

Any help is GREATLY appreciated.

Thanks

Concatenating Field For Multiple Records

May 30, 2008

Quick question. What I'm trying to do is concatenate a field for multiple records (hope that is worded in an understandable manner). Here's an example:

ID.....Code
5......33
5......23

ID.....Code...Result
5......33.....33 23
5......23.....33 23

I need the code to get the Result field. I know the code if you were to find the sum, min, max, etc...

(SELECT SUM(CODE)
FROM Table
WHERE ID = Table.ID) AS Result

But I don't know how to write it so it will combine strings.

hello dudes. i've got the following table:


table name: assassins

fields:
assassinid int, identity, primary key
assassinname nvarchar
assassincallsign nvarchar
knifekills int
sniperkills int
stealthkills int
fibergarotekills int


sample data:

2, Chuck Liddell, iceman, 30, 0, 0, 2
3, Timothy Oliphant, FortySeven, 100, 20, 150, 30

supposed i want to retreive only those records whose type of kills is on a given list, how do i do that? the list is actually dynamic since the kill types is actually coming from a checkbox on my page:
[] Knife Kills
[] Sniper Kills
[] Stealth Kills
[] Fibergarrote Kills

supposed i will only check Knife Kills, it will only retreive those records whose knifekills > 0

or if i check Snipers Kills and Stealth Kills, then those records whose sniperkills and stealthkills is > 0.

any of you know how to do that?

I'm very new at this so I hope I explained this right. I'd really appreciate any help I can get.

Select Many Records Into 1 Comma Seperated Field.

Oct 30, 2006

I want to pull out some information for documenting my user accounts.I want to be able to show all of the users and what companies those users have access to.

The table which stores the company information lists it in multiple rows, so there will be many results for each user
user -- companyid
johnd -- 2
johnd -- 5
johnd -- 1

I want to select this into one record so it will show up like this
user -- companies
johnd -- 2,5,1

The only way I know how to do this would be with a sub-query that uses a cursor to loop through & dump it into one string value, and then output the string value to the field. This seems extremely inefficient for such a seemingly simple task.

Can somebody help me out here?
thanks

dbo.Master.TotalAdv is numeric (dollar amount) and in this example the value is $1,850.00

dbo.CorpAdv.pID is an integer and unique ID for each record, later records have higher numbers
dbo.CorpAdv.AcctNum is text field
dbo.CorpAdv.AdvAmt is numeric (dollar amounts)

In A String Field Identify Not Date Records?

Hi All,

I have a table called Table1 with a field called DateString with a nvarchar type. The records are like this;

DateString

9/27/2006
2/22/2008

5/23/2007
2/16/2007
12345678900
11/20/2006

It may not have date records which are just string like in this example is 12345678900. I need a SQL script which can identify those records which are not of date type. Please help.

Multiple Records Tied To Foreign Key Field?

Jun 6, 2008

I'm a total newb to SQL so I apologize if I butcher the description of what I'm looking to do :) Hopefully the example makes more sense. Is it possible for a single record in 1 table to contain relationships to several records in a different table?

What I've got so far is 2 tables - Hardware and Software, with ID Specifying primary keys HardwareID and SoftwareID respectively. the hardware records are for computer details and the software obviously are for programs. What I need to be able to do is pull up a hardware record and be able to see what software is installed on it, and vice versa pull up a software record to see which computers it's installed on. The problem I'm running into is that a computer can have multiple programs installed on it and a program can be installed on multiple computers, so I don't know how to create that relationship to account for that.

What I'd like to see is in the Hardware table a column for SoftwareID that has a foreign key relationship to the SoftwareID field in the Software Table, and vice versa....My question though is is that possible to do and have potentially multiple separate records it links to from that same column field? I might have a computer with say Windows XP Pro, Office 2003 Standard, Adobe Acrobat 8 and a proprietary rate calculator program that i need each to be displayed with their details when I open that computer's record. Or on the software side if I need to see which computers a license is already installed on then I want to make sure I can pull up the full list of computers.

And finally if what I'd like to do isn't possible as I described it...any recommendations for a better way?

Thanks all for the help!

Conditional Return Of A Value From A Set Of Records As A Field Value In A Query

Dec 20, 2007

Hi,

I need to implement some thing like this.

I have a query like

SELECT table1.col1
,€™n/a€™ _response
FROM table1
INNER JOIN table2

This is the query that get the report data for my report. Now I need to replace the second column with an actual response like €˜accepted€™ and €˜rejected€™. And these values should be a result of evaluation of this form

Statusarray[] = ResponseStoredProcedure(table1.col1)

If(Statusarray.count < 1)
Set _response = €˜accepted€™
Else
Get Statusarray[1]
Compare this to Statusarray[0]
Set _response = some result based on comparision.

The _response returned in the query should return the actual response based on this evaluation where ResponseStoredProcedure is sent the current row value for table1.col1.

How can this be done in sql(using SQL Server 2005)

PLZZZ HELP!!!!!!!!!

Selecting Records Where Part-field Is Unique

Aug 10, 2015

I have a very large CSV file containing name-and-address information which I am reading in a Visual Basic project using the Microsoft.JetOLEDB.4.0 provider.

The key field on which the CSV file is to be filtered is the PostCode field.  This is a UK-format PostCode "XXnn Nxx" where "XX" is one or more letters denoting a geographical area within the UK and "nn" is one or more characters (starting with at least one numeric digit) which when combined with the area code denotes a specific district within the geographical area.  My aim is to identify all the unique UK postal districts held within my address CSV file.

Because I do not know how to use SQL to filter on the partial contents of a database field I am presently reduced to extracting unique full PostCodes using "SELECT DISTINCT PostCode,City,County FROM [ADDRESSES.csv]" into a DataTable object, then sequentially reading that DataTable using the operation of a dictionary object to identify unique PostCode areas, to finally construct the DataTable I need.

Is it possible in SQL to select records where the value of a varying number of characters before a space character in a given (PostCode) field is unique?

Resetting The Id (key Field) To 1 When Using DELETE To Clear Records From A Table

Feb 17, 2008

Is there a way that I can reset the key field to 1 when using DELETE to clear a table?
(Note: if there is a separate command that I could use after the DELETE, that is fine too.)
Thank you for your help with this,
-DJ

Splitting One Data Field With Hyphens To Separate Records

Feb 16, 2004

I receive a file that will have hyphens between data items such as
123-aed-edr-45r-ui9
1-ed3-45r-rrr-98u
I need to split the values to load into a table that will hold the 5 separate data itens. The fields will always have the hyphens but could be different lengths. Any idea on a best approach to split this in tsql

Need Help W/ SELECT From One Table, One Field, Multiple Unique Records

Apr 22, 2006

I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:

Anna Smith
John Doe

etc. I did not see IDs listed for any of the names in the table when I looked.

There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.

Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:

strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"

This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.

Is there a way to modify this statement to pull only the records that I want?

Thanks for any help you can give.
