Question : Sybase declare cursor

Wondering whether anyone could help out with a portion of a stored procedure I am having trouble with ?

     This is an example of a stored procedure I am trying to execute (this one works fine no errors:

create proc sp_tst1
as
     DECLARE @var1 char(10)
     DECLARE @message varchar(80)

     DECLARE title_curs cursor for
        SELECT var1 from myTable where key  = 3359
        open title_curs

     fetch title_curs into
          @var1

     if (@@sqlstatus = 2)
     begin
          print "no key found"
          close title_curs
          deallocate cursor title_curs
          return
     end

        while (@@sqlstatus = 0)
     begin
          select @message = ' this is the key ' +@var1
          print @message
          fetch title_curs into
               @var1
     end

     close title_curs
     deallocate cursor title_curs


But I want to make the SELECT statement dynamic say :

create proc sp_tst1
as
     DECLARE @var1 char(10)
     DECLARE @message varchar(80)
     DECLARE @tableName char(30)

     select @tableName = 'secdb..financial'

     EXEC ("DECLARE title_curs cursor for
                  SELECT var1 from " +@tableName+" where key = 3359
                  open title_curs")

     fetch title_curs into
          @var1

     if (@@sqlstatus = 2)
     begin
          print "no key found"
          close title_curs
          deallocate cursor title_curs
          return
     end

        while (@@sqlstatus = 0)
     begin
          select @message = ' this is the key' +@var1
          print @message
          fetch title_curs into
               @var1
     end

     close title_curs
     deallocate cursor title_curs

     

But when I run this I get :


The cursor 'title_curs' can not be used as it could not be found. It is possible that either it was not declared or it is not available in the current context.
(return status = -6)
(1 row affected)


I tried using local and global in front of keyword cursor but I believe that is Microsoft SQL syntax. What would I do for Sybase 11.0

Thanks!

Answer : Sybase declare cursor

this is my solution:

create proc sp_test
as
declare @var1 char(10),
       @message varchar(80),
       @tableName char(30)

  select @tableName = 'mytable'

  declare title_curs cursor for
  select fld1 from ' +@tableName+ 'where fld1 = 3273
  for read only /* this is change... regards */

  open title_curs

  while (1=1)
  begin
        fetch title_curs into @var1

        if @@sqlstatus = 0
        begin
              print 'no more records'
              break
        end

        select @message = 'this is the key ' + @var1
        print @message
  end

close title_curs
return 0
