No Unique Key / Avoid Dups
Oct 16, 2007
I have a table that I cannot create a unique key for because there is nothing unique and I can concatenate anything together to create one. I am looking for a way to import the data daily and have it only import what is not already in the table like a unique index would normally do. I don't want a sequencial number because that would do me any good. I need the record only in there once but I want to get all of the records in the new table. I have a date field with this if that at all helps. I am wondering if I could create a couple of feeder table to make this work but i am stuck. Any ideas on what to do? Thanks!!!

Ok, I have a table with about 47000 records in it. I have the following query for that table:Select ReportType =
Case
When ReportType = 1 Then 'Uniquery Report'
When ReportType = 2 Then 'SABRE Report'
When ReportType = 3 Then 'Menu Report'
Else Null
End,
ReportNameTo_,
Frequency.Frequency as Frequency,
ReportDate,
ReportDescription
From Report
Inner Join Frequency on ( Report.ReportFrequency = Frequency.FID )
Where ( Active = 1 )
And ReportDate = ( Select Max ( ReportDate ) From Report Where ( Active = 1 ) )
And ReportID = ( Select Max ( ReportID ) From Report Where ( Active = 1 ) )
The idea is that i need to get only the last report based off of unique reportname. I added a computer column to the table to give me the ReportNameTo_, since my deliminator is the _. Now my issue is that I have 1 records showing (the last record added to the table), which is right for the query that is written, but wrong for what I want. I need to only return the last record for each unique ReportNameTo_. So as an example, my table has the following ID, ReportNameTo_, Date fields the data looks something like this:
1, 123_, 1/1/20082, 123_, 1/1/20083, 124_, 1/1/20084, 124_, 1/1/20085, 125_, 1/1/20086, 125_, 1/1/20087, 126_, 1/1/20088, 126_, 1/1/2008
I only want to return the following:
2, 123_, 1/1/20084, 124_, 1/1/20086, 125_, 1/1/20088, 126_, 1/1/2008
Hope someone out there can let me know how to do this... I am almost there, just not all the way.

I need to delete duplicate records from a SQL table where only the key field is not a duplicate. I'm not having any luck with my script. Does anyone have a scrip that might work? Thanks

Hi all,
I have a table with multiple rows for the same member. For example:
Member1:
Id First_name Last_name
11111 John Joe
11111 John Joe
11111 John Joe
11111 Linda smith
Member2
Id First_name Last_name
22222 Jackie Smith
22222 Jackie Smith
22222 John Smith
22222 Aron Smith
I need to eliminate dups and
my result table should have two rows only:
Id First_name Last_name
11111 John Joe
22222 Jackie Smith
How am I going to do this?? Any ideas...
please.
Thanks,

Hassle free locating / reporting or deletion of duplicate rows in a SQL table based on the uniqueness of a column or columns that the user provides with a few nifty hands off features. Keywords: delete unique column record records
(This code may also be viewed at http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=576&lngWId=5
/*Description: UTILITY - Locate in MASTER
Syntax: EXEC sp_RemoveDups TableName, DupQualifierFieldNameList, DeleteDups, UniqueColName, CreateIdentColIfNeeded, StoredProcedureResult
Only the first two arguments are required
For HELP, enter the stored procedures name without any arguments or see the PRINT statements below
NO DELETION WILL OCCUR by default - only duplicate recordset returned. To delete records, pass in a 0 for the DeleteDups argument.
Example: EXEC sp_RemoveDups 'MyTable','LastName,FirstName,HomePhone'
Purpose: Allow removal of duplicate rows where
1. We define what fields qualify the duplicate
2. We select the unique rowid or it is detected automatically else no action takes place
Method:Delete by RowID all duplicate rows except the highest RowID (in alpha-sort sequence)
of each group of duplicates.

I have asked this question before and got some great answers, I just wanted to ask this again. I can detect dups easily, is there a way to get a total number of all dups so that I can delete a certain number at a time, then check the total again for verification that that specific number of dups are gone? I'm still using 2000. If I delete dups, won't it delete the 1 row I want to keep? And I do have a unique identity column.
thx,
Kat

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

What's the difference in the effect of the followings:
CREATE UNIQUE NONCLUSTERED INDEX
and
ALTER TABLE dbo.titles ADD CONSTRAINT
titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?
Which one do one use ?
thanks

BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?

I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code
Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword
and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
Thank You

insert into Test (code, prime) values ('BUS', cast(1 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('CAR', cast(1 as bit))
insert into Test (code, prime) values ('CAR', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(1 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))
select *
from Test
I need to create a constraint on this table that will not allow me to have two rows that are prime for the same code. So the following insert statement should fail:
-- This should fail
insert into Test (code, prime) values ('RLW', cast(1 as bit))
Thanks for you help!

I found some fragmented data pages in my database tables.
I have found out using DBCC Showcontig commands.
I want to remove data fragmentation.
My tables are replicated. Is it possible to remove fragmentation
without using export and import. Please help me in fixing this problem.
Is there any way to fix replication failure with out recreating it.
My replication has failed saying is timout error.error is could not connect
subscriber. But I can able to ping the subscriber and if I create a new publisher and subscriber it is working fine. But existing one is not working.
What might be the possible reason. We have recreated the replication. We droped the existing one and recreated it. It took around 14 hours to sync.
Is there any way to resync with out recreate publication. We are using transaction replication and merge replication.

Hi All,
Very Ad-hoc requirement I am having.
I've got one table with two columns.
Column Name Data Type
1) Id Integer Identity
2) RemDate DateTime
I've to write one SP/JOB in that there will be an integer input parameter @numofday.
Say value of @numofday is 5 then.... in SP/Job I need to insert 31 - 5 = 26 records to above-mentioned table where date starting from 1st of current month.
This logic can be achieve through looping but if anyone can suggest some better way to achieve this functionality without use of looping.
Thanks in advance,

Happy new year to all! Now a question...
I added a new column to StagePayments table - Activity - which is supposed to end up being the same as the JobActivityID from the JobActivities table. Basically, I need to get JobActivities (JA) info and put it in the StagePayment (SP) column.

I need to get SP to end up looking like this -
Seq Activity ActivityID
1 NULL NULL

I have tried various versions of this...
begin transaction
update StagePayment
set Activity = (Select J.JobActivityID
from JobActivities J (nolock)
inner join StagePayment SP (nolock) on J.JobID = SP.JobID and J.Description = SP.Activity)
where Activity is not NULL
way too basic as I get this error...
Server: Msg 512, Level 16, State 1, Line 2
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
I know somehow I have to get the duplicate Activities in the same sequence as the Descriptions, but that's where I'm stuck?!?
If anyone is able to offer suggestions on how to get this to update correctly, I'd be very happy to hear about it!
Thanks in advance!

Hi,
I need to query a database for a recordset and insert this into another database row-by-row.
For each record I want to provide a time of insert, but for each insert this time has to be incremented by 1, the time format is HH:MM:SS.0000 so for each inserted record the last decimal point would increment by 1.
Can I do this without a cursor ?
Any additional info I will provide gladly.
Thanks!

I am conducting stress testing for my website and keep getting deadlocks with the following message when one process is adding about 100 records per second and another process is trying to access the data:
Transaction (Process ID 499) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
What do I need to do in my stored procedures to avoid this? I only have ONE stored prcoedure that locks a row while incrementing an ID value. I am not doing any other locks, so is this a SQL Server system lock?
Any advise would be much appreciated. Thanks!

Application is a Work Tracking/Timesheet database.The increments of work are stored in the TimesheetItem table. Thiscontains, inter alia, the Work Code, the Start and the Duration thatthe employee spent that day on a particular project.Some employees in the Network Support Department don't complete astandard 7.5 hour day for various reasons, so for every Network Supportperson I need to update these particular days with an amount to bringthe total day's hours to 7.5.This SQL will get me a list of all TimesheetItem records for thepersonnel concerned.SELECTTimesheetItem.TypeID,[Work].WorkCode,TimesheetItem.Start AS Start,SUM(CAST(TimesheetItem.DurationMins AS float) / 60) AS HoursFROMTimesheetItem LEFT OUTER JOIN[Work] ON TimesheetItem.WorkID = [Work].WorkIDWHERE(TimesheetItem.EmployeeID IN(SELECT EmployeeID FROM Employee WHERE DepartmentID = 2))GROUP BYTimesheetItem.TypeID, TimesheetItem.Start, [Work].WorkCodeHAVING(TimesheetItem.Start >= @FromDate) AND (TimesheetItem.Start <= @ToDate)ORDER BYTimesheetItem.StartWhat I need is to group these records by EmployeeID where theaccumulated hours per day are < 7.5, so that I can then insert anincrement to make up the difference.I'm writing this from home and I don't have access to the tables toprovide a script, but there's nothing untoward there.Hope someone can help!ThanksEdward

I have a long sql batch that does this:1. Gets a list of all tables in user database that start with name COREdeclare@tablenamevarchar(30),@commandvarchar(2000),@cntintegerdeclare GetCOREOids cursor forselect sysobjects.namefrom sysobjectswhere ( OBJECTPROPERTY(sysobjects.id,N'IsUserTable')=1 ) and( sysobjects.name like 'CORE%' or sysobjects.name ='CMNSTRStructGeomBasicPort') and( sysobjects.name not like 'CORESpatialIndex%') and (sysobjects.namenot like 'COREDeletedObjects%') and( sysobjects.name not in('CORERelationOrigin','CORERelationDestination') ) and( sysobjects.id in ( select id from syscolumns where name = 'oid') )for read only2. Populates a temporary table with distinct oids from the list.create table [#tSP3DCoreOid] (oid UNIQUEIDENTIFIER)open GetCOREOidsfetch GetCOREOids into @tablenamewhile ( @@fetch_status = 0)beginselect @command = 'insert into [#tSP3DCoreOid] select distinct oid from' + @tablenameexecute(@command)--print @tablename + ' rows: ' + convert(char,@@rowcount)fetch GetCOREOids into @tablenameend /* while */--Clean upclose GetCOREOidsdeallocate GetCOREOids3. Creates a cursor to get "invalid" oids from 2 other tablesdeclare DanglingRelation cursor forselect oid from [dbo].[CORERelationOrigin] RO where not exists( select oid from [#tSP3DCoreOid] where oid = RO.oid )unionselect oid from [dbo].[CORERelationDestination] RD where not exists( select oid from [#tSP3DCoreOid] where oid = RD.oid )4. Loops thru. the cursor examining each oid and then calls aStoredProc to update another tabledeclare @objectOid uniqueidentifierdeclare @tempOid uniqueidentifieropen DanglingRelationfetch DanglingRelation into @ObjectOidwhile ( @@fetch_status = 0)beginset @tempOid='00000000-0000-0000-0000-000000000000'if left(@ObjectOid,8)='00000002'select @tempOid=oid from COREToDoList where Oid=@ObjectOidelse if left(@ObjectOid,8)='00000003'select @tempOid=oid from COREToDoRecord where Oid=@ObjectOidelse if left(@ObjectOid,8)='00000004'elseselect @tempOid=oid from COREBaseClass where Oid=@ObjectOidif @tempOid = '00000000-0000-0000-0000-000000000000'BEGINexec CORESetObjectIntegrity @ObjectOid, 2ENDfetch DanglingRelation into @ObjectOidendclose DanglingRelationdeallocate DanglingRelationdrop table [#tSP3DCoreOid]Now the #tSP3DCoreOid temp table can sometimes get as many as 7.5million rows and this is making the batch fail on SQLServer as it runsout of memory.I think the problem is the cursor here and would like somefeedback/tips on how to best optimise it.thanks a lotSunit

Hi, all!
Having a table with a varchar(10) column, I try to insert a row where the data for that column is more than 10 characters long. No surprise, I get a MSG 8152 error.
What I want is to get the overlong data clipped to the maximum column width, and no error. Is that possible?

Hi everyone,
As first task I've got Data Flow which loads a set of data into a .NET recordset.
After that, inmediately flow execution goes to For..Each Loop. I'd like to avoid go in that direction when Data Flow returns zero rows.
How can I do such thing?
I've tried this on Precedence Constraint Editor but it doesn't work..It doesn't recognize EOF keyword..
@[User::ResulSet] == EOF
Thanks in advance for your input,
Enric

Hi All,
I use a report expression something like this.
= SUM(Fields!MTD_TotNetCOAmt.Value)/SUM(Fields!TotBalance.Value)* 12
When Both fields have 0 vlaues, it gives a error massege. How do I avoid this?
Thanks
