Problem Inserting Large Amounts Of Text
Aug 12, 2005
I am running into a problem inserting large amounts of text into my table. Everything works well when I test with a few simple words but when I try to do a test with larger amounts of text (ie 35,000 characters) the appropriate field is left blank. The Insert still performs (all the other fields recieve their data, but the "Description" field is blank. I have tried this with both "text" and "ntext" datatypes. I am using a stored procedure with input parameters. As I mentioned, the query goes off flawlessly with small amounts of data (eg "Hi there!") but not with the larger amount.I check and the ntext field claims to be able to accept 1073741823 bytes of data. Is there some other thing I should consider with large amounts of text?

Does anyone have ideas on the best way to move large amounts of databetween tables? I am doing several simple insert/select statementsfrom a staging table to several holding tables, but because of thevolume it is taking an extraordinary amount of time. I consideredusing cursors but have read that may not be the best thing for thissituation.

this may seem like a simple question, but I have a report/lease agreement I need to put together and wanted to know the simpliest way to add large amounts of text. Basically its all the legal stuff most leases include in the amount of some 14 pages.
Should this be just one long string-- or does ssrs have another way to format this
thanks as always

I have a large text colum I am trying to insert into a DB
This colum is about 800 chars longs
I have set the colum type in the table to text
I have set the table option for text in row to on
I have set the table option for text in row to 1000
But it is still chopping the text at the 256 char mark on insert.
Anyone have any ideas ?? This is SQL 2000.

Hi,
I was wondering if any one could help me, I need to store large amounts of data in my database, at present I have it set to nvchar (8000), I've looked around and noticed you can use text which stores up to 2 million, but is slow in displaying the information.
Any ideas or points in the right directions would be great.
Thanks

We are looking to store a large amount of user data that will bechanged and accessed daily by a large number of people. We expectaround 6-8 million subscribers to our service with each record beingapproximately 2000-2500 bytes. The system needs to be running 24/7and therefore cannot be shut down. What is the best way to implementthis? We were thinking of setting up a cluster of servers to hold theinformation and another cluster to backup the information. Is thispractical?Also, what software is available out there that can distribute querycalls across different servers and to manage large amounts of queryrequests?Thank you in advance.Ben

Greetings
I need to be able to graph roughly about 150 employees/ supervisor and their monthly cell phone usage in minutes. I understand that I will need to group this on say one graph for every ten employees so it doesn't look messy and cluttered. I have read some threads here but they dont seem to work for me.
So again each supervisor has 100+ subordinates and I need to graph theie phone usage by month
thoughts???

I was wondering what is the fastest way to UPDATE lots of recods. I heard the fastest way to perform lots of inserts in to use SqlCeResultSet. Would this also be the fastest way to update already existing records? If so, is this the fastest way to do that:
1. Create a SqlCeCommand object.
2. Set the CommandText to select the datat I want to update
3. Call the command object's ExecuteResultSet method to create a SqlCeResultSet object
4. Call the result set object's Read method to advance to the next record
5. Use the result set object to update the values using the SqlCeResultSet.SetValue method and the Update method.
6. repeat steps 4 and 5
Also I was wondering do call the SqlCeResultSet.Update method once per row, or just once? Also would it be possible and faster to wrap all that in a transaction?
Would parameterized updates be faster?
Any help will be appreciated.

I have been looking into mirroring a large amount of small databases approx 150 databases.
As I understand this won't be feasible because of the way mirroring threading works, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=441900&SiteID=1
As I understand it for every database being mirrored sql will ping the mirror second, causing a network bottleneck?.
Also that the amount of threads generated for each mirrored database will cause also cause a bottleneck?
At the moment our database servers are under very little pressure and as an estimate use about 10% of the resources allocated to them such as CPU utilization, memory, disk IO and network. Our server hardware is Dual Quad core Xeons with 4 - 8 gig of memory and variety of 10k SCSCI raid configurations from raid 5 or 1,0 and sql 2005 32bit.
Ive done some calculations on the log file generation rate compared to network bandwidth there is more than enough network bandwidth.
Has anybody had any luck in mirroring many small databases?
My concerns is how much traffic is caused by the pinging of the mirror for each database?,
How many threads will the mirroring cause and what is the max amount of threads sql can handle?
How much memory will be consumed by each one of these mirroring threads?

p.s. my email was incorrect in the last mail.
Hi all,
is there a sql 2k thread. Am interseted in finding out what the largest database size of a sqlserver database people have worked with.
We have a 1.2 Terabyte db with about 150-200 million new rows being processed everyday. Would like to share some thoughts on this with other people who are working with this much data and what they are doing with it.

I'm in the process of migrating a lot of data (millions of rows, 4GB+of data) from an older SQL Server 7.0 database to a new SQL Server2000 machine.Time is not of the essence; my main concern during the migration isthat when I copy in the new data, the new database isn't paralyzed bythe amount of bulk copying being one. For this reason, I'm splittingthe data into one-month chunks (the data's all timestamped and goesback about 3 years), exporting as CSV, compressing the files, and thenimporting them on the target server. The reason I'm using CSV isbecause we may want to also copy this data to other non-SQL Serversystems later, and CSV is pretty universal. I'm also copying in thisformat because the target server is remotely hosted and is notaccessible by any method except FTP and Remote Desktop -- nodatabase-to-database copying allowed for security reasons.My questions:1) Given all of this, what would be the least intrusive way to copyover all this data? The target server has to remain running and berelatively uninterrupted. One of the issues that goes hand-in-handwith this is indexes: should I copy over all the data first and thencreate indexes, or allow SQL Server to rebuild indexes as I go?2) Another option is to make a SQL Server backup of the database fromthe old server, upload it, mount it, and then copy over the data. I'mworried that this would slow operations down to a crawl, though, whichis why I'm taking the piecemeal approach.Comments, suggestions, raw fish?

I know the standard Microsoft recommendation is to make the pagefile at least 1.5 to 3 times larger then the amount of physical memory. However, if you're talking about a server with lots of memory such as 16GB or 32GB, would following this rule be unnecessary. With SQL 2000 running on Windows 2000 Server or Windows Server 2003 I typically see pagefile usage no more then 12% for a 2GB pagefile. Anything over 15% means I need to look at other indicators to see if a memory bottleneck has developed. If I have 32GB of physical memory and make the pagefile only 1.5 x 32GB I have a 48GB pagefile. 10% of this is 4.8GB, which I would hope I never see consumed.
Any thoughts?
Thanks, Dave

HiI have a VB.net web page which generates a datatable of values (3 columns and on average about 1000-3000 rows).What is the best way to get this data table into an SQL Server? I can create a table on SQL Server no problem but I've found simply looping through the datatable and doing 1000-3000 insert statements is slow (a few seconds). I'd like to make this as streamlined as possible so was wondering is there is a native way to insert all records in a batch via ADO.net or something.Any ideas?ThanksEd

Hello,Currently we have a database, and it is our desire for it to be ableto store millions of records. The data in the table can be divided upby client, and it stores nothing but about 7 integers.| table || id | clientId | int1 | int2 | int 3 | ... |Right now, our benchmarks indicate a drastic increase in performanceif we divide the data into different tables. For example,table_clientA, table_clientB, table_clientC, despite the fact thetables contain the exact same columns. This however does not seem veryclean or elegant to me, and rather illogical since a database existsas a single file on the harddrive.| table_clientA || id | clientId | int1 | int2 | int 3 | ...| table_clientB || id | clientId | int1 | int2 | int 3 | ...| table_clientC || id | clientId | int1 | int2 | int 3 | ...Is there anyway to duplicate this increase in database performancegained by splitting the table, perhaps by using a certain type ofindex?Thanks,Jeff BrubakerSoftware Developer

I'm trying to move my current use of an sql 2000 db to sql 2005.
I need to update a table definition (to change a field to an Identity)
I'm getting a dialog box (in SQL server management studio) on save saying :
'xxxx' table
- Saving Definition Changes to tables with large amounts of data could
take a considerable amount of time. While changes are being
saved, table data will not be accessible.
I press 'Yes' to the dialog box.
After 35 seconds, I get another dialog box saying:
'xxxx' table
- Unable to modify table.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Well, the server is responding and I can query that talbe and other, I
can add/delete rows to other columns. I can modify other
(smaller) tables.
Any ideas where I can change this timeout?

Hi!
The DB I am working with has about 10 tables and some of the tables have 200,000 to 500,000 records. All tables have a clustered index on the primary key.
I performance during INSERT could be better I think - I add thousands of records at a time from many connections.
Is there a way to defer the update of indicies? So that, I can update the tables and then let the indicies regenerate ?
thanks,
Jas.

Is 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,
but for example after insertion of 1000 records) ?
I heard it should be possible with „bulk insert“ or with
transactions. Is it right ? I need do this with MS SQL Server 2005 (Workgroup
edition).
Thank you for your ideas!

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.

I'm trying to store a binary data file in my database. I've tried data types image, varchar(max) and text. I don't get error message on loading the data but as soon as the text file exceeds 32,000 bits a query returns an empty data set.
Is this a SSMS display problem and the data is really there? Or is this another one of Microsoft's memory bugs?

Hi!I want to store some really big text in my database (for my articles). The approximate size will be from 500 to 40000 characters. I was thinking of using the database 'text' datatype.I have heard that reading these text fields is slower and decreases the performance. Moreover is it advisable to index this for searching purposes?

Hi All,
How do I input a large text page (notepad) into a SQL column. Or assign a pointer to the data. I've tried to use BOL (writetext) and to no avail, I guess I'm missing something. I'm just using EM and Query analyzer. I thought this should be easy. Image data should work the same way.
TIA,
Dave
