XML Output is Truncated in SQL
I need开发者_StackOverflow中文版 to return my result set in XML and this works fine, but if the number of records are increased, my xml output is truncated
here is my query
select t.id,t.name,t.address from test FOR XML AUTO, ROOT('Response'), ELEMENTS
However I have set some option to increase the output result set like..
Tools --> Options --> Query Results --> SQL Server --> Results to Text --> Maximum
number of characters displayed in each column
Tools --> Options --> Results --> Maximum characters per column
but still I am unable to get my desired result.
please suggest my solution
EDIT: However when I click on the XML, it open in another query window and all xml shown here, but it not return all xml instead of truncated xml.
Thanks....
Try the following:
Declare @xmldata xml
set @xmldata = (select ... From test for xml...)
select @xmldata as returnXml
I've had the same problem with management studio and xml result sets. I've solved this by getting the output programatically with c#, with SqlDataReader.
This worked for me (SSMS 2012): Tools > Options > Query Results > SQL Server > Results to Grid: Maximum Characters Retried: XML data: Unlimited. Then I saved the results of the grid to a file.
I had the same issue. I changes my Query result setting to Unlimited, but it didnt work. There is a work around. Its not very neat, but if you do want to continue to use SQL Server Management studio and get the results. Tweak the query to convert the xml stored using:
convert(xml,'<xml><![CDATA[' + cast(MyColumnWithXml as varchar(max)) + ']]></xml>')
The complete text is returned. Please note you will have to do some formatting at you end
Just thought I'd add a quick addition to the answer above. Changing the settings in SSMS 2017 Tools > Options > Query Results > SQL Server > Results to Grid works. However you must then close SSMS entirely and re-open it for the setting to take effect.
If your XML result set is still being truncated even after changing SSMS Options, use the SQLCMD utility with :XML ON option prior to running your XML statement. Direct your output to a file using the -o switch. SQLCMD is a command line utility that is very simple to use. See http://msdn.microsoft.com/en-us/library/ms162773.aspx.
I know this question was asked like 10 Years ago, but still if someone is looking for a workaround which doesn't require any changes in the DB side and is a bit similar to the Accepted answer but not with SqlDataReader
.
You could make use of a DataTable
and fill it using the SqlDataAdapter
. Where your XML
data will be divided into multiple rows.
For Example
string xmloutput = "";
var cmd = new SqlCommand("<some sql query that returns data in xml format>", con);
var da = new SqlDataAdapter(cmd);
var dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
foreach (DataRow dr in dt.Rows)
{
xmloutput += dr[0].ToString();
}
Note:
- the above code assumes that the only one column is returned from
DB
withXML
data in it.
And later on, make use of the variable xmloutput
.
The XML output you get in Query output window is not really intended for saving valid XML documents. You can get valid XML out of SQL Server when you capture it as a stream using ADO or SQLXML managed classes in .NET
However you can limit the query output sizes by using In SQL Server Management Studio go to Tools >> Options >> Query Results >> SQL Server >> Results to Text >> Maximum number of characters displayed in each column
You can use SQL Management Studio for 2008 against a SQL Server 2005 database engine. If you do that, the defaults should be large enough, but in Tools -> Options -> Query Results -> SQL Server there is a Results to Grid and Results To Text node.
Results to Grid allows you to control the maximum size for XML data explicitly, and the default maximum size is 2MB.
If you don't have a license for SSMS 2008 you should be able to use the express edition for free here.
