dm_fts_parser inside try-catch block

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :Sql Server

Hi, I'm working on a project and have a code similar to the code posted below and I would like to understand why the CATCH block is never executed. If the try catch is removed the dm_fts_parser will send an error complaining search string syntax, however inside a try-catch block the code will silently return an empty recordset, no error is triggered and catch block is never executed.


USE master

      @StopWordListID int 
      , @SearchString varchar(1000) 
      , @WordBreakerLcid int 
      , @AccentSensitivity bit

      @SearchString = '"Introduction" OR "Repair and Service'
      , @WordBreakerLcid = 1033 -- English word breaker 
      , @AccentSensitivity = 0 -- Default is not accent sensitive

      @StopWordListID = ft.stoplist_id 
FROM    AdventureWorks2008.sys.tables t 
      INNER JOIN AdventureWorks2008.sys.fulltext_indexes ft ON ( t.object_id = ft.object_id ) 
WHERE   ( t.name = 'Document' )

        , LEFT ( dfp.special_term , 200 ) 
    FROM  AdventureWorks2008.sys.dm_fts_parser ( @SearchString , @WordBreakerLcid , @StopWordListID , @AccentSensitivity ) dfp
    PRINT 'Ok'
    PRINT 'Error'

Catch Block question

What are the scenarios in which a t-sql catch block will not be called?   I have a SP which does partition management, sometimes i see that partitions have not been properly created... but still the catch block was never called. This is getting very hard to debug.   Can it be that in some timeout scenarios the catch block is not called?

How to Add a Send Activity in a Workflow Service try/catch catch block?


For a Workflow Service that has ReceiveRequest/SendResponse Activities, you can right click on the ReceiveRequest Activity a do a Create SendReply to add multiple SendResponse Activities. 

The problem is that I want to have a Try/Catch block in the Workflow Service.  This way when a fault occurs, I want to log the exception in my database and then use a Send or a SendResponse Activity to send the fault information back to the caller of the workflow service.

Bottom line is that VS2010 does not allow me to add an additional SendReply Activity inside the catch block.

Do you know how to do this?

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.
