I have two tables which are related. The first table(A) has a sequentially assigned unique key (primary) that has a cluster index built on it. This table has roughly 1,000,000 rows of data and grows daily.
The second table(B) has a sequentially assigned unique key (primary). There is a column in table(B) which contains table(A)'s unique key. For each row in the table(A) there are roughly 30 rows in table(B).
Should I build a clustered index on the table(B) column which contains the key to table(A) or a non-clustered index?
I want to know is a flat file faster than a RDBMS for indexing for example a search engine indexing would a flat file be better in terms of performance, scalability etc than a RDBMS?
I have a CSV File, I am importing this into SQL Server using SSIS package through Flat File source Task.
Few Points about data & its handling 1) inside the Procedure they are dropping the index, then populating the table, then again creating the same index. 2) Data is huge in figure (say, in millions)
My doubt: which is the best way to import the data 1) Just inserting the data without dropping the Index 2) Drop index, populate table, re-create index (the way they do right now)
The other day we tried online re-indexing feature of SQL 2005 and it€™s performing faster than offline re-indexing. Could you please validate if it€™s supposed to do be this way? I always thought offline should be faster than online.
My records like below..I created a clustered index of DATE field .This is the only one index available in the table. The table contains nearly 5,00,000 records.Now after indexing the DB size increased from 14 GB to 26GB.
Recoverymodel OF DB is SIMPLE
Shall I shrink DB for reucing the size?Will it effect indexing????

This probably has been addressed before but I was unable to get the search to work properly on this site. I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example : Row 1 Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Row 2 Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc. Row3 Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc. Row 4 Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
I have data for online catalogue in SQL 7.0. The web grogrammer asked me to add a unique key for reference. I used int datatype with identity seed of 1 and increment of 1. This works fine BUT when I try to import new data I get an error because the csv file has no column and therefore no value for the unique field which will not allow null by definition.
How can I maintain a unique field to act as primary key in my data when I want to add (and delete) data that doesn't have this field.
I tried adding the uniqueidentifier field but this gives error message.
The only work round is to delete the unigue field altogether and then add the new data and afterwards create a new unique field. At 600000 + lines of data, this is time and memory consuming
I am creating a DTS package that is combining several tables, converting one column of data to a new column removing all special characters, then exporting the unique data based on this column and another column, and the max of other duplicates to a new table.
Now that I have the data in this table, I want to import any data that is not in my main table.
This "CLEANED" table does not have a designated "key" column, but the table I want to import the unique items does have an ID column that is also a primary key column.
DTS seems to want me to have a Key column to reference when importing from the CLEANED table to the MAIN table.
How would I go about checking the MAIN table against the CLEANED table, having DTS import only the unique items from the CLEANED table that are not present in the MAIN table based on three columns? The rest of the columns I want to just extract the MAX data from the duplicates.
Now here is the query I use to extract the unique values from the "CLEANING" table to get the data to the "CLEANED" table, but do not know how to use this to import into the MAIN table using something similar.
Code:
select partno2, MAX (partno) as partno, alt, MAX (C_alt) as C_alt, Max (cmpycd) as cmpycd, MAX (type) as type, compFN, MAX (pndesc) as pndesc, MAX (equipment) as equipment
into tbl_CLEANED from tbl_CLEANING group by partno2, alt, compFN ORDER BY partno, compFN
The three main columns I need to check against are: partno2 alt compFN I have named the columns the same in both tables.
partno2 is the column that has been copied from partno with all special characters & spaces removed. This is the main column I am using as a reference for unique values, then if no match, I have it check against the alt column, then the comFN column. If there are no matches in any of these columns, then I want to extract the data to the MAIN table.
How can I compare these tables and import only unique info to the MAIN table?
In addition, how can I also check items that are the same in both tables and update the MAX info for the other columns (not the three I use for reference - these I need to leave alone) and update those if there is more data in the CLEANED table then in the MAIN table?
I am using SQL Server 2005 Express Edition in conjunction with asp.net 2.0
Is there any way to guarantee when INSERTing data, that all values in a given column (which is of a char data type) are unique? Or do I have to do this programatically at the asp layer?

hello, i have two datasets. i want to insert all data from one dataset to other. i am using this:DataSet old = new DataSet(); download dd = new download();old = dd.contactlist("select", "admin", "001"); SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Project1ConnectionString"].ToString()); try {string cmd = "select * from contact"; SqlDataAdapter danew = new SqlDataAdapter(cmd, conn);DataSet dsOld = new DataSet();DataSet dsNew = new DataSet(); dsOld = old.Copy(); danew.Fill(dsNew); DataTable dtOld = dsOld.Tables[0];DataTable dtNew = dsNew.Tables[0];
dtNew.Rows.Add(row); }DataSet nds = dsNew.GetChanges();SqlCommandBuilder bld = new SqlCommandBuilder(danew); danew.Update(nds); } here rec_key is the primary key. this code works fine but it will insert all data from one dataset to other each time i click a button but i wanted that if data with a rec_key already exists will not insert. only unique values of rec_key will be inserted. i am using this code for this:foreach(DataRow rr in dtNew.Rows) { if (rr["rec_key"] == objRow["rec_key"]) { Response.Write("same"); } else { dtNew.Rows.Add(row); } } but this doesn't work. please guide me how can i do this. thanks
Hi - I've got a table in SQL server that has its unique ID field as binary data. I have a gridview displaying data from this table and I have set the datakey of this gridview as that binary data field.I have a 'Select' ciolumn in my gridview that, when selected, will display more details from the selected record. The problem is, how do I pass the selected id back to sql server bearing in mind that it's binary data? Here's what I'm doing at the moment:I have a function in my data accsess class that queries the database:Public Function getDetailsById(ByVal Id As System.Byte) As DataSet Dim con As New SqlConnection(conStr) Dim cmd As New SqlCommand("SELECT * FROM tableName WHERE Id=@Id", con) cmd.Parameters.Add("@Id", SqlDbType.Binary) cmd.Parameters("@Id").Value = Id Dim ds As New DataSet Dim adp As New SqlDataAdapter(cmd) adp.Fill(ds) Return ds End FunctionAnd then I call this function from my page with the gridview using: Dim da As New myDataAccess Dim ds As New DataSet ds = da.getDetailsById(GridView1.SelectedDataKey.Value)But I get the error:Conversion from type 'Byte()' to type 'Byte' is not valid.Any ideas where my data/code is going wrong? I'm not sure how to pass this sort of data around?Thanks
I just converted an old non-relational database into something that MS SQL likes. The old primary keys were broken up into two columns, one being useful. The column I need to use has some rows with the same values in them.
I am looking for some way in a SQL script to look for the duplicate rows and add "_X" to the data where X is a value incremented by 1 for each duplicate row found.
For example, 3 duplicate rows with "5443aa" would return "5443aa", "5443aa_1","5443aa_2".
i am looking for code to show the last entry of a database that has a unique field. for eg.. i have columns AREA, NAME, NUMBER. i need to show the last entry for each unique area. so if there was 5 seperate areas, the table would show the last five entries for each area. anyone help?
I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.
For example, I want to be able to save information like:
1. ITEM SERIAL NO = 12345 BRAND NAME = AA 2. ITEM SERIAL NO = 12345 BRAND NAME = BB.
Perhaps one too many 2000 DTS packages have permanently damaged my ability to think clearly - however, I've find myself very frustrated attempting to create a SSIS Data Flow which replaces a very simple 2000 DTS package.
Take data from table1 in database1, put it in table2 in database2. Table2 in Database2 has an additional column as part of the primary key - so I need to add an arbitrary unique value in each row as it's inserted. Previously, I did this in the transformation script through a variable I incremented.
What's the recommend method to do this now - since row level processing of variables seem to be a no-no?
The tables are populated in the following order: One row for CallDetail, One for Call and one for Request and so on

Man I do come up with strange scenarios, but that is the joy of working in software field right ? ;-) First off, thanks to anyone taking their time to read this, and Ihope this post paints a clearer picture better than my previous posts.
I have an old stored procedure (which I didn't create) that produces a dataset of the following:-
((All names and values had been changed to protect confidentiality))
region agent_type mailpackage1 mailpackage2 mailpackage3 New York Agenttype1 2000 2300 0 New York Agenttype2 0 0 5 New York Agenttype3 150 2 4000 Central Agenttype2 1234 5678 9 Central Agenttype4 435 1 0 MidWest Agenttype1 555 0 0 West Agenttype1 1 45 0 West Agenttype2 0 2 3
A little bit of explanation:- Each region can have any type of agents, specified by the number to distinguish different agent types. these agent types mail specific packages to their customers depending on the situation and what the customers asked for. the numbers in each mail package indicate the total that had been sent out by a particular type of an agent. So in this case we are not dealing wtih how many agents are there, just how many packages had been sent out by a specific type of an agent in a region.
Previously the report was produced like you would see in the above dataset. However the client would want it the other way around. Though I didn't show it here, there are plenty of other packages but I am picking three for clarity sake.
So the "new" Report would have to look something like this.
---------- break Page -------------------- and so on
I had created a table in the RS that looked like the above with expressions written into the each cell that holds a value. The expression is
=IIF(Fields!agent_type = "AgentType1", mailpackage1.Value, Cint(0)) in the first row, first column of the table. =IIF(Fields!agent_type = "AgentType1", mailpackage2.Value, Cint(0)) in the second row, first column of the table. =IIF(Fields!agent_type = "AgentType1", mailpackage3.Value, Cint(0)) in the third row, First column of the table. And so on....... alternating between agent_type and mailpackage for each cell.
Grouping1: Group by Region, insert page after each group.
What happened was the following:- ((I am putting the first region, because it is also happening for the other regions too)
(on a side note, this region didn't print out AgentType4 because there were no data associated with it)
The question is, is there anything else I could have done to prevent this ? as you can see, the data is correct and placed in their right cells but somehow, they won't join together. I got a feelin that it has something to do with the expression that I had put in each cell.
Can someone help or point me in the right direction ? This is really bothering me and I couldn't figure out why it was doing this. Couldnt find any links or maybe i am putting in the wrong keywords in the search. Thanks muchly !
I am trying to achieve the below problem statement, however I am getting stuck at the looping part.
EX: We have three columns
First Name |Â Last Name | Mothers Name
I want to generate the username field using above columns, so lets consider, I have following data
First Name | Last Name | Mothers Name a                   b                 cdef a                   b                 cdfg a                   b                 cdfj
Expected Usernames:
1: a.b 2: a.b.c 3. a.b.cd
Basically, it has to be FirstName.LastName.(incremental letters from MothersName until the name becomes unique)

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?
I have two tables in my database called CartItems and OrderItems. Istore all of a session's shopping cart items in the CartItems tableusing the sessionID as the identifier (called cartID in my DB). Afteran order is placed and is approved, I would like to copy all of theitems in the CartItems table for that given cartID to the OrderItemstable given a new orderID.I will know the cartID and orderID ahead of time and would like tosend them both into a stored procedure and have the transfer takeplace.Example:take this data...CartItems (table)--------------------------------------cartID | itemID | quantity | price--------------------------------------12345 2 1 12.9512345 7 2 17.95and make it this data...OrderItems (table)--------------------------------------orderID | itemID | quantity | price--------------------------------------00001 2 1 12.9500001 7 2 17.95via some stored procedure that I send (@cartID,@orderID)Any help would be greatly appreciated!!
I am sorry if this is the wrong forum for this question but I can not find better fit. I am using Visual Studio 2005 to write an asp.net web site which includes an SQL data base. In the databaseI have a table called 'ACCOUNTS' which has primary key column called 'ID' and a nvarchar column called 'Name'. I want the values in the 'Name' column to be unique in the table so that all accounts have unique names. I don't want to make the 'Name' column the primary key because I want people to be able to change the name of their account after it has been created. It seems to me there must be some way to add such a constraint to the table but I can find none. I have searched the documentation and seen loads of references to unique columns but I can't find any way to set a column to unique thru the IDE (or any other way). Can anyone help me? Thanks in advance for any help.
I am new to MDM profisee tool and currently working for Addres verification project for my organization.I wanted to clear my doubts here about Unique Identifer in Stage table and how it works.. Here what i understand till now:
Step 1) I created an Entity using MDM profisee UIÂ and it generated a stage table in MDS database called stg.Address_leaf Step 2) I have loaded data from external source to MDS stage table using ETLÂ and passed Import type as 2 and Import status id as 0 Step 3) I have run store procudure system generated something stg.udp_Address_leaf to load the model and passed the version name as Version_1, Log flag as '1'Â and Batch tag as 'Address'
Now my below are my questions: 1) What is the field i can use in MDS stage table to populate my unique intifier value coming from source? (lets say Address_Id is my Unique value for all the records coming from source) 2)  Where/how Unique Identifier is useful in this process? Will this be useful in next time load from stage to Model? 3) If i truncate and load my MDS stage table in next run and few earlier records has been updated how it will update those records in Model? will this process (code present in SP) recognize by Unique Identier column present in MDS stage table?
