FORCE_LEGACY_CARDINALITY_ESTIMATION option causes formatting and in some cases loss of intellisense

arjunkrishna

Hello,
   I recently upgraded from 9.x to 9.4.4.7199 version of sql prompt and I noticed that adding 
 OPTION ( USE HINT ( 'FORCE_LEGACY_CARDINALITY_ESTIMATION' )) causes sql prompt to not format it correctly.

 In some large sql procs, it completely stops giving intellisense and starts adding random text when trying to auto complete etc.

created a sample

ALTER PROCEDURE dbo.testProc

    @endDate DATE = NULL

AS

    BEGIN

        IF OBJECT_ID(N'tempdb..#temp') IS NOT NULL

            DROP TABLE #temp;

        CREATE TABLE #temp ( ReleaseDate DATE NOT NULL );

        INSERT INTO #temp ( ReleaseDate )

                    SELECT t.TradeDate FROM ( VALUES ( '1/1/2019' )) AS t ( TradeDate )

        OPTION ( USE HINT ( 'FORCE_LEGACY_CARDINALITY_ESTIMATION' ));

        --intellisense/autocomplete works here

        --SELECT * FROM #temp AS t;

        UPDATE ite SET ite.ReleaseDate = '1/1/2010' FROM #temp AS ite

        OPTION ( USE HINT ( 'FORCE_LEGACY_CARDINALITY_ESTIMATION' ));

        --intellisense/autocomplete is lost if hint in the update is used. if we comment out the hint, then it starts working here as well.

        --if you take all these statements out of a proc, then intellisense/autocomplete works.

        SELECT * FROM #temp;

    END;

after opening a ticket and no resolution at this time... I would like the formatting module to be open sourced so that if we can fix it, then we can compile that dll and drop it into our local machine to remove such small annoyances.
