Re[2]: [python-sybase] Problem with calling stored procedures

[Harri P. <har...@tr...>]

I replied to this from home, and the mailing list barked at that, so here
it goes again.  Sorry if you get it twice.  See below for a simple testcase
for the presumed bug.

I finally fished from my disk the old testcase I sent your way last November, 
which still should exhibit the problem:

I wrote:

After some tests, I got a fairly minimal test case that should also fail for
you.  The preceding 'select' somehow throws the 'sp_helpindex' call off
balance.

import Sybase
Sybase._ctx.debug = 1
db = Sybase.connect('SYBASE', 'sa', '', 'pubs2')

def test(table):
    print "Test table:", table
    c = db.cursor()
    c.execute('select * from '+table)
    c.fetchall()
    c.close()
    cmd = "sp_helpindex %s" % table
    print db.execute(cmd)

test('authors')
