This is a general question on the best way to import a large amount of data
to a MS-SQL DB.
I can have the data in just about any format I need to, I just don't know
how to import the data. I some experience with SQL but not much.
There is about 1500 to 2000 lines of data. I am looking for the best way to
get this amount of data in on a monthly basis.
Any help is greatly thanked!!

I need to delete data from a particular table which has more than half a million records. The data needs to be deleted is more than 200,000 records from the table. What is the best way to delete the data from the table other than importing into a temporary table and performing the same operation?
Let me know if the strategy to be followed is okay.
1. Drop all the triggers
2. Drop all the indexes
3. Write a procedure with a loop setting ROWCOUNT to 1000 and delete the records. ( since if I try to delete all the rows it will give timeout error )
The above procedure will delete 1000 records for each batch inside the loop till it wipes out all the data for the specified condition.
4. Recreate Indexes and Triggers.
Please let me know if there are any other optimal solution.
Thanx,

Hi,I am using SQL 2000 and has a table that contains more than 2 millionrows of data (and growing). Right now, I have encountered 2 problems:1) Sometimes, when I try to query against this table, I would get sqlcommand time out. Hence, I did more testing with Query Analyser and tofind out that the same queries would not always take about the sametime to be executed. Could anyone please tell me what would affect thespeed of the query and what is the most important thing among all thefactors? (I could think of the opened connections, server'sCPU/Memory...)2) I am not sure if 2 million rows is considered a lot or not, however,it start to take 5~10 seconds for me to finish some simple queries. Iam wondering what is the best practices to handle this amount of datawhile having a decent performance?Thank you,Charlie Chang[Charlies224@hotmail.com]

My application needs to retrieve data from a table which has more than 15 lakh records. The records keep increasing in thousands every 15 days.
Is there anyway i can reduce the time to retrieve? basically i have a select statement with a few conditions and a clause for the id's of these records.
Hi Experts:
We have several database linked via merge replications. Due to business requirements, we need to delete 5M rows in one table, we did it on one subscriber. However, the publisher kept uploading the deletion operations from the subscriber and blocked any downloading operation from publisher to subscriber. How can we acceralte the replications now as this has already operated in 2 days, and will continue 1-2 days? Is it possible to set the publisher take the downloading before uploading? How to speed up large amount data deletion operations in replication environment?
Thanks in advance!

I have an interesting challenge. we are not allowed to allow users direct access to data in our SQL Server. Audit requires us to take the data out of our production server and pass it to the user. my situation is i have a table in SQl with over 100,000 records and growing. i want to pass that to an access data base. i am utilizing DTS and a data transform.
i s there a better way? the package is running slow and even appears to freeze. i see this amount of data as growing as well.

Recently we added a new table into our SQL2000 database specifically to store scanned in images of documents. This new table contains a PK field, a couple of datetime fields, a couple of char(1) fields and one 'image' field.
Before adding this table, the database size was approx 6GB. Six months after adding this new table, the database has grown to 18GB - 11GB of this is due to the scanned in images.
Would this new table affect the SQL performance with regards to accessing other data in the database that has nothing related to the new table?
If so, would moving this new table into it's own database be recommended?
Thanks

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)
View 2 Replies View Relatedguys,I have a project need to move more than 100,000 records from onedatabase table to another database table every week. Currently, usersinput date range from web UI, my store procedure will take those dateranges to INSERT records to a table in another database, then deletethe records, but it will take really long time to finish this action(up to 1 or 2 hours).My question is if there is some other way I should do to speed up theaction, I am thinking about use bcp to copy those records to datafileand then use bcp to insert it into SQL Server table. Is this the rightway to do it or should I consider other solution (then, what is thesolution.)Thanks a lot!
View 8 Replies View RelatedI was wondering if anyone can help me.
I am trying to import data into SQL Server 7. The table will be 700-800 columns, and the data will be about 150,000 records at a time.
The data source is flat file.
First I create the table using a database schema, and secondly I would like to populate the table.
The problem is that most of the data is numeric, and to be used for statistical analysis.
So far I have tried Bulk Insert, bcp, and dts.
DTS is the only method that has worked in any way, shape or form, but that requires importing each column as a Varchar. Importing to my pre-created table doesn't work, because it is interpreting some of the source columns as character data and refusing to insert them into an int field.
Bulk Insert and bcp both give error messages, and I am wondering if that is because of the size of the insert statement that is required to handle so many fields.
For the moment I am just trying to import the data in any way, but eventually, it will have to be run as an automated process, with the table structure probably needing to be altered as well.
Any help/suggestions would be very greatfully received.
We have created a databse in SQL Server 7 for support issues.
We are having trouble with only one aspect of the databse and that is the body of the supported problem.
The databse is basically a Question/Answer Support database whch house Frequently Asked Questions.
When the user does a search on a specific problem they have a list of matching questions shows on the screen (links).
When the question is clicked on it shows the Questions with the Answer of possible fixes.
Our problem lies in the fact that SQL server is truncating the Answer portion. I have tried different Data Types with maximum lengths with no success it keeps truncating it.
Right now I am on Data Type nvarchar with a length of 4000.
If anyone has any pointers on how to solve this problem all input is appreciated. You can post here to the forum or e-mail me directly at jason@flnet.com
Thank You.

Hello,I have experienced that some of my tables occupies an extremely large amountof pages but with few rows. An example is a table with 37 rows over 22000pages !. The columns are simple integer and char. I fixed the problem byintroducing a clustered index. Now it only uses 1 page. But can anyoneexplain this behaviour in SQLServer 2000 ?regards Jakob Mathiasen
View 4 Replies View RelatedIs there any way how to create indexies after insertion of any
number of records (I dont want to create index after insertion of every record,

I heard it should be possible with „bulk insert“ or with

View 3 Replies View RelatedHello all - I currently have a project that has a gridview on the front end. The user can select multiple items from this grid, hit a button and all of the selected records should be updated in the process. However, this resultset can have a large amount of data coming back, and I'm stumped on how to pass all of the ID's to the sp. I'd rather not call the SP for each record selected, as there could be 1,000 items selected, and well, I'd rather not call the SP 1000 times :p. I thought of generating a comma delimited list as I'm looping through the grid and using dynamic sql, but the IDs are about 6-7 numbers long, and including comma, would take up almost all of the max space in a varchar.
Are there any good solutions to this problem? Passing the items as an array? Generating a data table in .NET and passing that?
Any help would be appreciated.

How can I make a recursive algorithm in TSQL without using a large amount of resources?
New hires are put on a 6 month probation period, Their probation ends at the 6 month mark + sick time isnull(floor(sick_hours/8),0) they accrued during that 6 months. Their accrued sick days are added to the 6 month probation period to establish a new probation end date.
I then have to do the following loop:
1)Determine if any of the days between the original probation end date and the new probation end date have any weekend days or holidays for a particular employee.
2)If it does, I add those days to the new probation end date to create a newer probation end date.
a.I then go back up to step 1).
3)If it does not, I jump out of loop and look at the next employee on probation.
Note: I already have coding for determining number of sick days accumulated during an employee’s probation period. Recursive CTE? Recursive function? Other?
A friend reminded me of a problem we tried to solve a few years ago and were unsuccessful. Below is a copy of the email he sent me. We would very much appreciate any ideas from the community. Thanks!Lets start with a simple schema where you have 4
tables:
I am having a small problem.
When I generate a report with a large amount of text data (Paragraphs) the report will not split the text between two pages.
It will move the entire text box to the next page leaving a large amount of space on the previous page.
I tried every control on the page to render this. I tried textboxes, tables, lists, rectangles, subreports, etc..
The data is stored in a SQL table using a text data type (there can be a large amount of data entered into these database.
Any help on this would be great. I like reporting services, but there are just a few bugs.
I am using Reporting Services 2000 with Service Pack 2 and Hotfix

In the full recovery model, if i run a transaction that inserts 10MB of data into a table, then 10 MB of data is moved in the data file. Does this mean then that the log file will grow by exactly 10MB as well?
I understand that all transactions are logged to the log file to enable rollback and point in time recovery, but what is actually physically stored in the log file for this transactions record? Is it the text of the command from the transaction or the actual physical data from that transaction?
I ask because say if I have two drives, one with 5MB/s write speed for the log file and one with 10MB/s write speed for the data file, if I start trying to insert 10 MB of data per second into the table, am I going to be limited to 5MB/s by the log file drive, or is SQL server not going to try and log all 10 MB each second to the log file?
Importing data from an Access database, I cannot overcome the limit of 1,000 records.
In DTS, I "copy one or more tables", select tables, run, and cannot see my 1,052 entries.
Where can I set a max size of ~1,500 in my sql target base?
Hello, All:
I have many, many Access databases that are roughly 1.5GB-3GBs each and they have millions of records. Each MS Access Database file corresponds to one Database in SQL server. I'm trying to simply transform the data as it is in Access to MS SQL 2005.
I'm using the 64 bit version of Windows Server 2003 and the 64 bit version of SQL 2005. The server is running four dual core AMD Operton processors and has 8GB of RAM with a 1TB RAID 5 configuration. I think the hardware should be sufficient but the SQL Server Import and Export Wizard can't seem to handle the large number of tables/records. If I do one table at a time, it works well; however, it produces the following error message whenever I try to import the entire database:
Pre-execute (Error)

Hi,
I am making a SSIS package that imports data from a application using a custom ODBC driver. The field in the application is set to be a "longvarchar" type field and can be from 2 characters to 2MB of data.
I've created a ODBC data connection in the SSIS package and use a "DataReader Source" to read the data I need. The sql statement is very simple
Select log from tablename
When I try to run the SSIS package with that statement it just goes to yellow on the DataReader Source and stops. It stays like that until I stop it. If I select other fields except for that field it works fine. Also I've been able to get it to succeed getting the log field if I select a log record that's not too big. The largest one I've been able to get is 800 characters, but I got one with 2500 characters that just stops on yellow.
In the Progress log the last line says:
[DTS.Pipeline] Information: Execute phase is beginning.
Does anyone have any ideas on how to resolve this?
Hi,
I am currently importing (and exporting) binary flat files to and from Db fields using the TEXTPTR and UPDATETEXT (or READTEXT for export) functions. This allows me to fetch/send the data in manageable packet sizes without the need to load complete files into RAM first.
Given that some files can be up to 1Gb in size I am keen to find out a new way of doing this since the announcement that TEXTPTR, READTEXT and UPDATETEXT are going to be removed from T-SQL.
I had a quick foray into SSIS but couldn't find anything suitable which brings me back to T-SQL. If anyone knows a nice elegant way of doing this and is prepared to share, that would be grand.
Thanks for your time,
Paul
I need to create script that will import large XML files (500 - 7GB) on a daily basis and store the data in a relational db structure.
What is the best and fastest way of importing such files. I have played around with smaller files and found the following.
1. SSIS XML Data Source: It doesn't seem to like the complex elements types and throws out the file.
2. Using Bulk File Import, sorting the file in XML variable and using XQuery to parse the file: This works but it can't take a file more than 2GB in size, so I can't use this method.
3. C# + XML Serialization: This also works, but seems to be terribly slow. I open the DB connection once, so it doesn't open and close for each db call, but still seems like it takes a long time.
how to import large XML quickly in a relational table structure?

I'm creating a temporary table in a Sql 2005 stored procedure that contains the transaction amount entered in a period <= the period the user enters.
I can return that amount in my result set. But I also need to separate out by account the amounts just in the period = the period the user enters. There can be many entries or no entries in any period. I populate the temporary table this way:
SELECT
t.gl7accountsid,
a.accountnumber,
a.description,
a.category,
t.POSTDATE,
t.poststatus,
t.TRANSACTIONTYPE,
t.AMOUNT,
case
when t.transactiontype=2 then amount * (-1)
else amount
end as transamount,
t.ENCUMBRANCESTATUS,
t.gl7fiscalperiodsid
FROM
UrsinusCollege.dbo.gl7accounts a
join
ursinuscollege.dbo.gl7transactions t on
a.gl7accountsid=t.gl7accountsid
where
(t.gl7fiscalperiodsid >= 97
And
t.gl7fiscalperiodsid<=@FiscalPeriod_identifier)
And poststatus in (2,3)
and left(a.accountnumber,5) between '2-110' and '2-999'
And right(a.accountnumber,4) > 7149
And not(right(a.accountnumber,4)) in ('7171','7897')
order by a.accountnumber
Later I create a temporary table that contains budget information. I join these 2 temporary tables to produce my result set. But I don't know how to get the information for just one period. For example, if the user enters 99 as the FiscalPeriod_identifier, I need a separate field that contains only those amounts(if any) that were entered for each account in Period 99.
Can anyone help? It may be that I am not seeing the forest for the trees, but I can't figure it out.
Thanks very much.
Sue
