Problem Of Duplicate Records With A Simple Insert Statement !
I am using a simple stored proc shown below which inserts a record and updates the same record field
called SortID with the Primary Key Column data of the same record.
Everything was working fine until few days back. The site has been deployed 2 years back and was LIVE ever since.
We have got thousands of records in this Credits table. The table field called SortID is used
for moving the credits up and down.
My problem is now after 2 years of deploying the table has got duplicate records, suprisingly a same credit is appearing
under different MemberID and with the same SortID.
How are these duplicate records inserted with a simple insert statement & update ??
Is this a Locking problem or Transaction problem I have no idea.
Any ideas will be of great help
Thanks in Advance

Mark Duplicate Records In A Select Statement ?
I have a requirement to mark duplicate records when I pull them from the database. However, I only want to mark the 2nd, 3rd, 4th etc record - not the first one. The code I have below creates a column called Dupes but marks all the duplicates - including the first one. Is there a way to only mark the 2nd, 3rd, 4th etc record ? SELECT *, cs.CallStatusDescription as CSRStatusDesc, cs2.CallStatusDescription as CustomerStatusDesc, (Select MAX(CallAttemptNumber)From CallResults cr Where cl.Id = cr.CallLogId) as CallAttemptNumber, Dupes = (select count(id) from CallLogswhere (CustomerHomePhone != '' AND cl.CustomerHomePhone = CustomerHomePhone)OR (CustomerBusinessPhone != '' AND cl.CustomerBusinessPhone = CustomerBusinessPhone)AND DealerId= 'hdsh' AND CSRStatus IS NULLand datediff(d, logdate, getdate()) <= 21), FROM CallLogs cl left Join CallStatus cs on cs.Id = cl.CSRstatusleft Join CallStatus cs2 on cs2.Id = cl.Customerstatus Where SaleStage IN ('1', '2', '3', '4', '5', '6') And (LogProcessFlag = 1 Or LogProcessFlag = 0)And DealerId='hdsh'And Logdate Between '08/01/2007' And '08/31/2007'

Insert That Drops Duplicate Records
I ought to know how to do this, but it escapes me at the moment. I need to write an insert statement for a table that will be based on a complex select query. The select query may return rows that are already in the target table. In that case, I don't want duplicates created, but I don't want the query to error, either. I can't remember how to set that up.

Duplicate Records Are Being Inserted With One Insert Command.
This is like the bug from hell. It is kind of hard to explain, soplease bear with me.Background Info: SQL Server 7.0, on an NT box, Active Server pageswith Javascript, using ADO objects.I'm inserting simple records into a table. But one insert command isplacing 2 or 3 records into the table. The 'extra' records, have thesame data as the previous insert incident, (except for the timestamp).Here is an example. Follow the values of the 'Search String' field:I inserted one record at a time, in the following order (And only oneinsert per item):airplanejetdogcatmousetigerAfter this, I should have had 6 records in the table. But, I endedup with 11!Here is what was recorded in the database:Vid DateTime Type ProductName SearchString NumResultscgcgGeorgeWeb3 Fri Sep 26 09:48:26 PDT 2003 i null airplane 112cgcgGeorgeWeb3 Fri Sep 26 09:49:37 PDT 2003 i null jet 52cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null dog 49cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null jet 52cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null jet 52cgcgGeorgeWeb3 Fri Sep 26 09:50:22 PDT 2003 i null dog 49cgcgGeorgeWeb3 Fri Sep 26 09:50:22 PDT 2003 i null cat 75cgcgGeorgeWeb3 Fri Sep 26 09:52:53 PDT 2003 i null mouse 64cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null tiger 14cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null mouse 64cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null mouse 64Look at the timestamps, and notice which ones are the same.I did one insert for 'dog' , but notice how 2 'jet' records wereinsertedat the same time. Then, when I inserted the 'cat' record, another'dog' record was inserted. I waited awhile, and inserted mouse, andonly the mouse was inserted. But soon after, I inserted 'tiger', and 2more mouse records were inserted.If I wait awhile between inserts, then no extra records are inserted.( Notice 'airplane', and the first 'mouse' entries. ) But if I insertrecords right after one another, then the second record insertion alsoinserts a record with data from the 1st insertion.Here is the complete function, in Javascript (The main code ofinterestmay start at the Query = "INSERT ... statement):----------------------------------------------------------------------//Write SearchTrack Record ------------------------------------Search.prototype.writeSearchTrackRec = function(){Response.Write ("<br>Calling function writeSearchTrack "); // fordebugvar Query;var vid;var type = "i"; // Type is imagevar Q = "', '";var datetime = "GETDATE()";//Get the Vid// First - try to get from the outVid var of Cookieinctry{vid = outVid;}catch(e){vid = Request.Cookies("CGIVid"); // Gets cookie id valuevid = ""+vid;if (vid == 'undefined' || vid == ""){vid = "ImageSearchNoVid";}}try{Query = "INSERT SearchTrack (Vid, Type, SearchString, DateTime,NumResults) ";Query += "VALUES ('"+vid+Q+type+Q+this.searchString+"',"+datetime+","+this.numResults+ ")";this.cmd.CommandText = Query;this.cmd.Execute();}catch(e){writeGenericErrLog("Insert SearchTrack failed", "Vid: "+vid+"- SearchString:: "+this.searchString+" - NumResults: "+this.numResults, e.description);}}//end-----------------------------------------------------------------I also wrote a non-object oriented function, and created the commandobject inside the function. But I had the same results.I know that the function is not getting called multiple timesbecause I print out a message each time it is called.This really stumps me. I'll really appreciate any help you canoffer.Thanks,George

Cannot Insert Duplicate Key Row In Object 'dbo.blabla..' With Unique Index 'Idx_blablabl'. The Statement Has Been Terminated. At
We are developing a project that is expected to hold TB of data and the back end used is SQL Server 2005. I have the following problem I have applied Nonclustered index over a column on a table. Designed a SP for insertion which caters for updation incase the criteria based on the input is met. The logic goes like this Incase there exists a row containing the value of the column that is indexed for uniqueness, there should be updation. If not there should be a new row created. However often there is an error message that is placed above. This happens only on some of the SPs and only on rare occasions. Can any body tell me if there is any problem with the SQL Server 2005 Thanks in advance R Suresh, SQLDBA

Insert / Update In Master Table And Also Save A History Of Changed Records : Using Data Flow/simple Sql Queries
Hi, My scenario: I have a master securities table which has 7 fields. As a part of the daily process I am uploading flat files into database tables. The flat files contains the master(static) security data as well as the analytics(transaction) data. I need to 1) separate the master (static) data from the flat files, 2) check whether that data is present in the master table, if not then insert that data into the master table 3) If data present then move that existing record to an history table and then update the main master table. All the 7 fields need to be checked to uniquely identify a single record in the master table. How can this be done? Whether we can us a combination of data flow items or write a sql procedure to do all this. Thanks in advance for your help. Regards, $wapnil

1 Log File Can Contain More Records After Performing Backup Database Statement, 2 Why Can't Insert Data When Is Log Is Not Full
question 1: i found that database log file can contain more records after performing backup database statement. for example: i create a database and limit the log file to 2mb. then i create a table and insert data. If i backup the database before i insert data , the database file can contain 192 records unitl the log file is full. If i don't perform the 'backup database' statement. The 'dbcc sqlperf(logspace)' indicate the utilization ratio is less than 40% after inserting 192 records why? I list my code: Code Snippet create database db_test on primary ( name=db_test, filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf' ) log on ( name=db_test_log, filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf', maxsize=2mb ) go backup database db_test to disk='db_test.bak' --- if i don't execute this line, log file can contain a lot of record go create table db_test..table1(col char(8000)) --insert data to fill up the database log declare @n int set @n=0 while @n<192 begin insert into db_test..table1 values(replicate('a',8000)) set @n=@n+1 end question 2: i create a database and limit the log file to 2mb. Then i create a table and insert data in an endless loop. After the inserting operation executing for a while, the 9002 error occurs, indicate the log file for the database is full. But the 'dbcc sqlperf(logspace)' command indicate the unilization ratio is low, and log_reuse_wait_desc in sys.database is 'CHECKPOINT' And I can insert data , and i'm sure the state of log_use_wait_desc is 'CHECKPOINT'. As i known, the checkpoint can't truncate log under full recovery model. Only the back log operation can truncate the transaction log. So log is not full, why 9002 error is encounterd. and why the log_reuse_wait_desc return 'CHECKPOINT'? I list my code: Code Snippet create database db_test on primary ( name=db_test, filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf' ) log on ( name=db_test_log, filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf', maxsize=2mb ) go create table db_test..table1(col char(8000)) --insert data to fill up the database log declare @n int set @n=0 while @n<>-1 begin insert into db_test..table1 values(replicate('a',8000)) end any suggestions? thanks in advance.

Duplicate Records
Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago. Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work. The problem: Number Fname Lname Age ID 123 John Franklin 43 1 123 Jane Franklin 40 2 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 29 6 126 Fred Johnson 39 7 127 Gene Simmons 47 8 The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included. If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field. Number Fname Lname Age ID 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 39 7 127 Gene Simmons 47 8 If anyone remembers this discussion, mainly the date, I would really appreciate it.

I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link).

Duplicate Records
Hi, Not so sure how simple this question is but here is what happened. I installed SQL Server 2005 on a new Win Server 2003. I exported the tables and their data from the old machine to the newly established database on the new machine. It looks like all my records were duplicated. When I try to delete one of the duplicates it won't work because both rows are effected. I can't set my primary key now and if I try to create a new database with the primary key already set than the import fails. Any one run into this before or know what's going on? Any help ASAP would really be appreciated. Thanks, Alice

Records Duplicate When Edited...?
Hi,I have written a web application using dreamweaver MX, asp.net, and MSsql server 2005.The problem I am having occurs when I attempt to edit a record. I have setup a datagrid with freeform fields so that the user can click on edit, make the required changes within the data grid then click update. The data is then saved to the database. All this was created using dreameaver and most of the code was automatically generated for me.The problem is that, not everytime, but sometimes when I go to edit a record once I hit the update button to save the changes the record is duplicated 1 or more times. This doesnt happen everytime but when it does it duplicates the record between 1 and about 5 times. I have double checked everything but cannot find anything obvious that may be causing this issue. Does anyone have any suggestions as to what I should look for? Is this a coding error or something wrong with MSsql? Any ideas?Thanks in advance-Mitch

Page 2 - Duplicate Records
okay, great, this is something to work on let's start with the subquery called "d" this subquery appears to have lost its UNION, but that's okay, you can add that back in later the part that didn't work right is that you must reference the columns of "d" by their correct names, and these names are those that you assigned in the subquery so it should look like this: Code: SELECT [WO Id] , MAX([Want Date]) AS max_Want_Date , SUM([End Qty]) AS Sum_End_Qty , ... FROM ( SELECT WORK_ORDER.DESIRED_WANT_DATE AS 'Want Date' , WORK_ORDER.BASE_ID AS 'WO Id' , WORK_ORDER.DESIRED_QTY AS 'End Qty' , WORK_ORDER.PART_ID AS 'Part ID' , NULL , OPERATION.RESOURCE_ID AS Resource , PART.DESCRIPTION AS Description , NULL FROM PART INNER JOIN ( WORK_ORDER INNER JOIN OPERATION ON ... ) as d GROUP BY [WO Id] does this make sense?

I have a table that holds the following 1 7530568 87143 OESCHD 1/5/2006 6:31:58 AM 1 7530568 87143 OESCHD 1/5/2006 7:02:36 AM for each 7530568 ordernumber there should only be one OESCHD status. This is the query I'm using to insert the data sent to me. INSERT INTO ORDER_EVENTS SELECT d.division as division, dt.orderNum as orderNum, dt.poNum as poNum, dt.statusCode as statusCode, dt.statusChangeDate as statusChangeDate FROM dt_Order_Events dt INNER JOIN division d ON dt.division = d.divisionShort INNER JOIN status s ON s.division = d.division AND s.statCode = dt.statusCode WHERE directive <> 'C' AND dt.orderNum IN (SELECT orderNum FROM ORDER_HEADER) This works fine when used with in the hourly transactional update. But When I ran it for the Bulk UpDate (so we'd have historical data) it allowed orders to have statuses to many times. I am not a SQL guru, I have no idea how to write a sql statement or stored proc that will remove the duplicate records. or how to change what I have to prevent further ones. Any help would be apreciated.
