Unhandled Exception

One of our developers gets this error when caching a DB with SQLPrompt on a box on which they have restricted access.

Interestingly if the cache db entry is deleted first the error is handled better and returned in a SQL Prompt error box, but the gist is still the same.

This is the error: 
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
 
For example:
 
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
 
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Using SQL Profiler I think this is the statement, and it ties in with the error message 
SELECT so.name AS TableName,
sys.schemas.name AS TableOwner, 
cc.name AS ConstraintName,
cc.object_id AS Constraint_id,
cc.is_not_for_replication AS NotForReplication,
cc.is_not_trusted AS WithNoCheck,
cc.is_disabled AS Disabled,
sc.name AS ColumnName,
cc.parent_column_id AS colid, 
cc.definition AS Text
FROM sys.check_constraints cc WITH (NOLOCK) 
INNER JOIN sys.objects so WITH (NOLOCK) ON so.object_id=cc.parent_object_id 
LEFT JOIN sys.schemas WITH (NOLOCK) ON sys.schemas.schema_id=so.schema_id
LEFT JOIN sys.columns sc ON sc.column_id=cc.parent_column_id AND sc.object_id=cc.parent_object_id 
ORDER BY so.name, cc.name

when I run it, it pulls back all the data. When the developer runs it the Text column is NULLs.

I'm guessing this is to do with permissions, since I know SQL 2005 locks down a lot more of the view privileges.
The developer is in the db_datareader role.

I'm not sure how SQL Prompt should handle this, since a user not having access to some of the system data is valid, but certainly barfing isn't the best :)

Versions:
- Microsoft SQL Server Management Studio 9.00.3042.00
- SQL Prompt 3.5.0.333

Cheers, Robin.

    Hi Robin,


    Thanks for reporting this. It's been filed as a bug and fixed this morning. It'll be available in the 3.6 final release, which we're now thinking will be out early-mid next week. We've made a couple of other fixes as well so we need some additional test time.


    Cheers,
    Bart
