Hi there!!
I have a table say Emp with index as (Empid) which is a autoincreament field.
How do I update names of already existing rows having identified Empid.
Complexity lies with the fact that I cannot use Emp table as Destination table because if i do so then it will insert new rows and empid will change.
Thanks and Regards

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..
I'm having a bit of problem putting together a query that will update records in one table from another table. I've got 2 tables lets call them tblA and tblB.In tblA there is EID(int), QID(int), OID(int) and in tblB OID(int) and QID(int). Also there is an input parameter @EID.What I want to have happen is when someone inputs @EID then tblB gets updated from tblA. To give you a heads up there are no PKs or FKs in either of the tables.If there is an OID in tblA it takes the QID from tblA and places it in tblB where OID from tblA and tblB match.Hopefully this makes sense I thought that I could do something like this:CREATE PROCEDURE test3(@EID int)AS UPDATE tblUsedSET QuestionID = (select QuestionID from tblExamQuestions where ExamID = @EID)WHERE OrderID = (select OrderID from tblExamQuestions where ExamID = @EID)GOBut I get an error that says that there are to many records being returned by the subqueries.

I am trying to update a large table which consists of 45 million records , it is taking more than 2 days to the update , below is my approach
1. The table has only one clustered index and no other indexes on the table.
2. I am updating in batches say 20000 record-wise.
3. Changed the recovery mode to bulk logged and auto-growth size is set to  300MB and there is enough space in my disk for transaction log .
But still the query is running slowly.
Hi,Currently we're a building a metadatadriven datawarehouse in SQLServer 2000. We're investigating the possibility of the updatingtables with enormeous number of updates and insert and the use ofcheckpoints (for simple recovery and Backup Log for full recovery).On several website people speak about full transaction log and thepace of growing can't keep up with the update. Therefore we want tocreate a script which flushes the dirty pages to the disk. It's notquite clear to me how it works. Questions we have is:* How does the process of updating, insert and deleting works with SQLServer 2000 with respect to log cache, log file, buffer cache, commit,checkpoint, etc?What happens when?* As far as i can see now: i'm thinking of creating chunks of data of1000 records with a checkpoint after the Query. SQL server has thedefault of implicit transactions and so it will not need a commit.Something like this?* How do i create chunks of 1000 records automatically withoutcreating a identity field or something. Is there something like SELECTNEXT 1000?Greetz,Hennie

Hello, I am pretty new with SQL Server 2005.
I have installed SQL Server Express Edition. I have migrated a set of tables from Oracl10g (by using Microsoft's Migration Tool Kit).While I am trying the following simple update command, the session hangs and it never finishes !!!!!!!!!!!!
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
select pos_key from pos_station where staff_key = 1105
POS_KEY
=======
NULL
update pos_station set pos_key = 1 where staff_key = 1105
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The table has a few constraints and a couple of indices in place.
Then I create another table (but no contraints or indices), just copy the data from the problematic one and the update WORKS (in msecs) :
update pos_station_new set pos_key = 1 where staff_key = 1105
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Is there any way to tell if the table (any table in SQL Server) is corrupted or not ?
How can I tell if a session is waiting for something and what is that something ?
Thank you very much for your help.

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?
i have a total of 5 records to update. one being a summary row and the other four being 1,2,3,4 record ids. is there any way to update these 4 records w/o using 4 seperate updates???
thanks,

First off, Ive been asking a lot of questions lately and I want to sincerely thank those who have been posting VERY helpful replies. I have learned much in these past few weeks.
That being said I have hopefully one of my last questions before this project is complete.
Im running a DTS that imports data from a flat text file and updates 6 different tables. In one of my tables, "PERSON", I only want the records to be inserted or updated if the FCN field is new, or unique.
Here is my code that updates the table (without regard for uniquneess):
INSERT INTO PERSON (FIRST_NAME, LAST_NAME, MIDDLE_NAME, FCN)
SELECT "FIRST", "LAST", "MIDDLE", FCN
FROM DATAGRAB WHERE RECORD_DATE = convert(varchar(8), getdate()-1, 112)
How can I convert it to only update records with a unique FCN value?
Ive posted on here many times before and got the answers, so hopefully this time will be like the rest...you guys are SO good at SQL.
I have a database that has lots of fields. I use some specialised email marketing software that allows me contact each record. What I have done in the past is export the contacts i wanted to email and then format the columns like this: (all done in excel)
EmailAddress Website Salutation Website1 Website2 Website 3
info@eg.co.uk www.eg.co.uk David eg.co.uk Eg.Co.Uk Eg
test@red.co.uk www.red.co.uk Sue red.co.uk Red.Co.Uk Sue
After each list looks like this, i then import this data into Access and from there our email software pics up the data and emails accordingly.
Now here comes the problem...
We have decided that we now want everything done within our sql database. Which means we want clickthroughs recording and open rates etc all appearing in our database. (we have all this sorted out)
However we dont have Website1, 2 or 3 fields in our database. We know that they need to be included in our db somewhere but with half a million contacts we don't want to do it one by one obviously.
We want a simple where we export all our contacts and then format them so they include website1, 2 and 3. THEN we want to import them, simply updating the contacts with that new data. (Or is there a SQL way of creating temp tables so these fields dont even need to be included in the db?)
I hope i managed to explain myself in way you can all understand.
Thanks

I have a table with 5 columns (col1, col2, col3, col4). I want to do is:
1) To check if any two records are duplicates (if the the values in col1 of record A are identical to Record B, two records are considered as duplicates);

Here's a problem that I can't find anyone else has run into. I'm usingAccess and SQL Server, but the theory would be the same for any db.I have a large number of tables that contain linked records(intersection tables mostly). In the interest of space, I'llillustrate an example:tblStudents (ID, Name)tblTeachers (ID, Name)tblClasses (ID, Name)tblEnroll (StudentID,ClassID,TeacherID)I have about 10 people who each use a separatecopy of this database (in access). I want them (at the end of eachday) to be ableto update all the records that they entered that day into a databasethat I have setup on a server (SQL Server 2005). Both databases havethe exact same structure.Caveat 1: All of the classes, students, and teachers are not the sameon each database, but the server database should contain all of them.Caveat 2: There is no way for the clients to automatically insert intothe server, they are offsite and out of range.Herein lies the problem: when a record is inserted into the server froma client, all of the links are lost since the ID will be different onthe server that it was on the client.I don't think a simple update / insert query will work, and most db'sand languages don't play nice with recordset appends.What are your thoughts??

I have a following problem: I€™m importing records from an Access table into a SQL Server Table. I€™m using lookup to determine if a record already exists in the SQL Server table and in that case I should update the record if it was modified.
I thought of using OLE DB Destination for new records (done, works fine) and OLE DB Command Transformation to update the modified records. It all works but the thing that bothers me is that my table has approx. 40 columns so my OLE DB Command is very long (update table set col1 = ?, col2 = ?, col3 = ? €¦€¦). The other problem is that I€™m always updating all the columns even if only one column was modified.
Is there a better way to update the existing records?
Any help is appreciated.
Thanx
Sara
Dear All,
I want to use SSIS in order to synchronize data. The OLEDB and ADO.NET Destination Adapter just inserts the rows read from the source. Since I have PK Constraint on destination, the tranform fails. How can I ask to update the records in destination DB?

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.
View 4 Replies View RelatedI wrote a sproc which does four things:
1. It looks at an option master to see if the record exists before inserting a new one
2. If the record is not there it inserts the optino record
3. Once the record is inserted I have to run a CASE statement on the record to determine its level
4. Once the level is determined, the record needs to be updated with the correct level.
1-3 work fine (when run without the update command).

Paging is implemented for fast response since the data pool is very large up to 10000000.
The above query works fine in testing. However, in reality, since new records are keep inserting to the tables, I have concern about the accuracy of viewing another page of result.
E.g. Â At 12:00pm, the result of page 1 (5 per page) Â is
R20, R19, R18, R17, R16
After 2 mins, 12:02pm, the user press next page button
Since records R21, R22, R23, R24, R25, R26 are inserted
page 2 result would be R21, R20, R19, R18, R17
So the result is showing many records same as page 1 which has already been seen. Could this situation be improved?
I am seeing a strange behavior in a script component that I can't figure out.
Basically, there is a field in my script that checks to see if a string field is length of 1. If it is, it updates the field with some value. The strange behavior is that it picks up some of the rows but not others.
If Row.FieldValue.Length = 1 Then
Row.FieldValue= "Some Value"
End If
I've tried variations such as:
If left(Row.FieldValue.,1) = "-" Then
Row.FieldValue= "Some Value"

and Table2.Dimension in (Select Dimension from Table1)
In Table1 There might be 10 Groupid records all of which are different.

I currently have a table called stores. I've just added a uniqueidentifier column called store_guid to the stores table. The table currently has about 500 records in it and now i'm trying to set each store_guid = to a newid(). I've tried using UPDATE stores SET store_guid = newid() . however, that doesn't work because i think it's trying to set each record equal to the same guid using that approach. All i need to do is fill in my new column with new guids. any ideas?

This is a general question regarding the use of view and storedprocedures. I'm fairly new to databases and SQL.I've created a SQL database using an Access Data Project ("ADP") andI'm satified with the table structure. I've moved on to building somefront ends for our users.I'm running into situations where I want subreports to be built fromqueries [views or stored procedures-I don't know which to use so I usethe term query] that are dependent on the values in other controls.I've played with stored procedures and I've figured out how to sendcriteria to a stored procedure and then dynamically change the recordsource of a subreport.However, I'm running into cases where I can't add records to theresults of a stored procedure. The table I'm running a stored procedureon has five fields: (1) Primary Key for each record, (2) FundID that'sa primary key in another table, (3) CompanyID that's a primary key inanother table, (4) Attribute 1 of the (Fund/Company) and (5) Attribute2 of the (Fund/Company).The stored procedure filters the set of Fund/Companies based on aFundID from a form. I can update this stored procedure. However, forusers, they would like to see the Fund Name from the table that hasunique FundIDs. As soon as I include that into the stored procedure, Ican no longer add records.My questions are many:1. Is there a primer online that discusses the theory behind myquestion? Recordsets, updatability, working with recordsets in forms?2. What are some best practices for developing subreports, combo boxes,list boxes, etc. where the data is dependent on the values in a control3. I'm struggling with the best ways to grab objects on a form. If I'mon the main form I'm comfortable working with theMe.__object__.__sub-oject routine. However, if I'm in one subform whereI need another subform to change based on the record I'm in, I feelthat my code to get at the subform is very klunky..forms.main form name.sub form name.form.record sourceI don't even know how I figured out the "form" part before recordsource. Again, are there some basic rules or guides about navigatingthrough forms in VBA?4. Should I be developing front ends in some other environment?I know it's a lot, but all the advice from the newsgroups seems topresuppose some knowledge about how ADP, ADO, ODBC..blah blah and Ican't seem to find any documents about ADP and SQL.
