SQL Server 2008 :: Size Limitation For XML Data Type?
Oct 7, 2015
I've never worked with the XML data type in SQL Server, although I know its been there for a few iterations of SQL SErver. Now I've got a situation in which it might store some configuration data as XML, since that's the way it comes. (We had thought about storing the data in a VARCHAR(MAX) field.)
The first question is does the XML data type have a size limitation? For example do you do something like:
ConfigFile XML(1000) NULL
Or is it just something like this:
ConfigFile XML NULL
The second question is persisting the data to a file. As the name I choose for the variable suggests, we want to save the data from a configuration file into a SQL Server database. How do we go about doing that? We'll be developing a C# application, it will read and write the data both from the SQL table and the user's local HD.
There are some more columns with more 'nvarchar' (max) and other INT data types. Anyway, I know a page is 8K size. How do I find out how much space does A ROW takes with above datatypes? If users add 5000 Rows per day, how do I figure out how much size the table will increase?
HI Everyone, I understand that there is a 4GB size limitation on SQL Server Express edition. right? What I want to know is what if a database file created in SQL Express is hosted with SQL Server 2005 will the file still have the 4 GB size limitations? Thanks
We have installed SQL Server 2008 R2 SP1 instance and it's having Share Point 2010 databases.
We have 2 dedicated drives for Tempdb on SAN with 50 GB space. Both tempdb data & log files are created with default size. I would like to presize them.
What are the best values to start with?
U ->Tempdbdata having tempdb.mdf file V->Tempdblog having templog.ldf file
I'm using the SQL below to work out recruitment figures. The query works well, but I now need to build this query into a DotNet application as a webpage. I therefore need to declare and manipulate the values such as 'Total', 'Jan' to 'Dec' and 'YearRecruited' in order to write these values into my chosen data control. I therefore need to know the datatypes of these calculated values.
Total I think is straightforward as DNAScreeningID is an int datatype. But what about the others?
SELECT YEAR(SamplingDate) AS YearRecruited,
COUNT(CASE WHEN month(SamplingDate) = 1 THEN DNAScreeningID END) AS 'Jan', COUNT(CASE WHEN month(SamplingDate) = 2 THEN DNAScreeningID END) AS 'Feb', COUNT(CASE WHEN month(SamplingDate) = 3 THEN DNAScreeningID END) AS 'Mar', COUNT(CASE WHEN month(SamplingDate) = 4 THEN DNAScreeningID END) AS 'Apr',
Should data type money allow nulls? Are there valid arguments both pro and con?
Yes, there is the age-old question regarding how one might interpret a NULL found in any column - does it mean the amount is not known or that the amount is zero (in the case of a numeric type)? You get the drift...
Other than that, though - are there any practical considerations an old data hound ought to be aware of?
I am having an issue fetching Chinese characters in a XML data type. It return questions mark (?).
Below is the sample script.
DECLARE @XMLVAR XML SET @XMLVAR = '<?xml version="1.0"?> <POLICY_SEARCH xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <NAME>QA*保险1</NAME><NUMBER /></POLICY_SEARCH>'
SELECTI.xmlParam.query('./NAME').value('.','NVARCHAR(25)') NAME ,I.xmlParam.query('./NUMBER').value('.','NVARCHAR(25)') NUMBER FROM@XMLVAR.nodes('POLICY_SEARCH') AS I(xmlParam)
I have problem to execute query with interval date.
If try this query I don't have problem and the output is correct:
SELECT * FROM dotable WHERE dotableDate BETWEEN CONVERT (datetime, '01/01/2015', 121) AND CONVERT (datetime, '09/01/2015', 121);Instead if try this I have error: SELECT * FROM dotable WHERE dotableDate BETWEEN CONVERT (datetime, '25/01/2015', 121) AND CONVERT (datetime, '28/01/2015', 121);
[Err] 22007 - [SQL Server]The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Not seeing the Review Data Type Mapping Screen in SQL Server Import and Export Wizard?
Is there only a certain version where that screen shows up?
I am trying to import data from an MS Access application to SQL Server and all of the connections are good, but some of the data isn't and if I let it migrate using this tool it crashes on the bad data and there is no data that migrates. The Review Data Type Mapping screen will allow me to bypass the records in error and load the rest. however, I can;t do that if I cannot see the screen.
I get the following error : "Msg 8115, Level 16, State 8, Line 1.. Arithmetic overflow error converting nvarchar to data type numeric. The statement has been terminated."
The table is set to nvarchar, and i am just trying to make the prices go up 10%.
I found an article that stated that there was a limit of 1GB of total user databases for SQL on Small Business Server. I could not tell if that was SBS 2003 or an earlier version. Does anyone know if there is any limitation?
I have created a backup device. THe file it wrote (.dat) is 1.2 gig when I tried to run another backup to it it failed (3sec) Is there a size limitation on the Device or .dat file size?
Just testing things out I tried to directly open this file and it gave me a memory problem(Try closing other applications not enough memory to open "filename").

I am using FileSystemTask to copy around 4 gb file(ASCII). Is there any limitation on the file size. SQL Server 2005 SP2, Windows 2003 server. Copying from one Windows 2K server to other Windows 2K server. Thank you,
Im just wondering, does the Execute SQL task have a length limitation of how long the SQL statement can be, I tried to copy and paste a very long SQL statement from my DTS execute job task to a new SSIS execute SQL task and the statement was truncated and I cannot enter anymore text after that
I am running 7.0 standard desktop on Workstation 4.0 and have run into a database size limitation of 10GB. I have all the newest patches and have found no documentation that refers to a 10GB limitation. A September copy of VBA developer says that this edition has a limitation of 4GB while the guides say that the Small Business Server edition would have a 10GB limitation. All other forms of documentation say that there should be the standard mega-terabyte limit. I'm completely confused by this [lack of] documentation. Any help???
I need to store images in MS SQL. I have the upload procedures and stuff but I'm missing the point about the image data type size.
It is supposed to be able to store up to 2Gb!!! but when I declare the data field image I can't specify the max size for the field and by default is 16 !!
16 bytes!! what can I do with that? How can I insert a file?
I'm using ODBC to interface a Microsoft SQL Server 2000. One of theoperations involves placing files within BLOBs. I'm using the imagedata type for this purpose. Most of the time this works okey, but whentrying to add a 21,3 MB file I get an error. The error code is 22001,which means "String right-truncation". But why? Does this mean thatthe field cannot accepts BLOBs with this size?
I've got a few VLDB's that we want to make smaller. Since the tables are running on legacy stuff, all of it's basically made with int's and char's and it's horriably inefficant.
The problem that I came across is when I made a new table with the best data types and copied the data from the old table, the table size was the exact size (excluding the index size). It was estimated that a total of ~20 GB would be saved with this change. As it turned out, 0 bytes of data were saved with the data types chagnes.
Why are the two tables the same, even though one has much more efficant data types?
If you want more information about the table I'm using:
391 columns. 50,147,035 rows. 65,295.625 MB in size.
Out of Memory when working with big XML Files:when validating XSD it process small files but when size close to 1gb it throws .I have 16 xml files out of which 8-10 files size will be around 1gb processing one by one in FOR EACH LOOP container in SSIS[XML Task] Error: An error occurred with the following error message: "Exception of type 'System.OutOfMemoryException' was thrown.".Task XSD Validation failed.
system configuration : processor:Intel(R) Xeon (R) CPU E5-2670 v2 @2.50GhZ 2.50 Hz Installed memory (RAM): 61 GB System type: 64 -Bit operating System Visual studio:2012,32 bit virtual memory : 12499 MB
whether the size of the XML Document a limitation for the validation task ? or any system configuration i need to improve?
I have a sharepoint content database in sql 2008 R2 (WSS_Content) that is at 230Gb size, but has 40% of it is empty space. This is because we have removed a large amount of old content from sharepoint. The log file is fine. I have 60GB left in my drive that host the database files. I would like to shrink the datafile to get disk space back. I found that under the files property, the WSS_Content data file's initial size is 228702 MB (220 Gb or so).
When i try to do a shrink file (data file) from management studio, i see the 60 GB of drive space keep dropping. So i have to kill the process. what i should do to reduce this data file.
why it keep using up all the free space in the drive when i try to shrink the data file?
