SYMPTOMS
You use the Count attribute in the FetchXml schema to create a query against
the Microsoft Dynamics CRM database. Then, you set the Count attribute to
20,000. In this scenario, the number of search results that is returned is
5,000. Additionally, the SELECT statement in the SQL language is always SELECT
TOP 5001 regardless of what is set for the Count attribute and for the Paging
attribute.
CAUSE
This issue occurs when you use the FetchXml schema to retrieve a resulting
search set and when the moreRecords attribute is set to 1. The value of 1
indicates that more than 5,000 records are available. In Microsoft Dynamics
CRM, the Paging attribute has a page limit of 5,000.
RESOLUTION
Microsoft provides programming examples for illustration only, without warranty
either expressed or implied. This includes, but is not limited to, the implied
warranties of merchantability or fitness for a particular purpose. This article
assumes that you are familiar with the programming language that is being
demonstrated and with the tools that are used to create and to debug
procedures. Microsoft support engineers can help explain the functionality of a
particular procedure. However, they will not modify these examples to provide
added functionality or construct
procedures to meet your specific requirements.
To resolve this issue, use the Paging attribute to retrieve records. Then, use
the moreRecords attribute in the resulting search set to determine whether the
next page should be returned.
For example, the following code demonstrates how to resolve this issue.
moreRecords = true;
i = 0;
while(moreRecords)
{
get page i
if(result has more records)
i++
else
moreRecords = false
}
MORE INFORMATIONc Warning Serious problems might occur if you modify the
registry incorrectly by using Registry Editor or by using another method. These
problems might require that you reinstall the operating system. Microsoft
cannot guarantee that these problems can be solved. Modify the registry at your
own risk. To adjust the page limit to a value that is less than 5,000, add
the MaxRowsPerPage DWORD Value to the registry. To do this, follow these steps:
1. Click Start, click Run, type regedit in the Open box, and
then click OK.
2. Locate and then select the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\MSCRM
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type MaxRowsPerPage, and then press ENTER.
5. Right-click MaxRowsPerPage, and then click Modify.
6. Type a number that is less than or equal to 5,000 in the
Value data box, and then click OK.
7. On the File menu, click Exit.
To turn off the paging feature and then ignore the MaxRowsPerPage parameter of
5,000, add the TurnOffFetchThrottling DWORD Value to the registry. To do this,
follow these steps.
Note Performing these steps may cause performance issues on your computer.
1. Click Start, click Run, type regedit in the Open box, and
then click OK.
2. Locate and then select the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\MSCRM
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type TurnOffFetchThrottling, and then press ENTER.
5. Right-click TurnOffFetchThrottling, and then click Modify.
6. Type a number other than 0 in the Value data box, and then
click OK.
Note Step 6 lets you retrieve the number of records specified in the Count
attribute of your fetch statement.
7. On the File menu, click Exit.
