  WHEN SQL profiling I see this code popping up it takes 5-10 seconds to run, but i do not understand what is doing? Why is the the code being excuted through sp_cursorprepexec ?

  When its excuted by it self it takes a few mil seconds. what are all those paramters for? where do they go? Why is sp_cursorprepexec used?

  Many thanks

  declare @P1 int

  set @P1=4211

  declare @P2 int

  set @P2=180151118

  declare @P3 int

  set @P3=1

  declare @P4 int

  set @P4=1

  declare @P5 int

  set @P5=12

  exec sp_cursorprepexec @P1 output, @P2 output, NULL, N'Select r.READCODE, r.APPLIEDFROMDATE, r.RCTEXT, r.FREETXT, r.EPILINEKEY, ci.ENTEREDBY, ci.ACCESSLEVEL from SC_READCODES r left outer join SC_CONFIDENTIAL ci on r.EPILINEKEY = ci.EPILINEKEY where r.PATIENTKEY = ### and r.SIGNIFICANT = 1 and len(isnull(convert(varchar(10), r.APPLIEDTODATE, 103), '''')) = 0 order by r.APPLIEDFROMDATE desc
