Re: [Python-sybase-misc] select into and v.039

[Sébastien S. <sa...@us...>]

Great, now can you try the following code (adding select=False at the 
end of execute):

import apresdb
c2 = apresdb.instance.cursor()
c2.execute("select iv0.ProdId, iv0.Account, iv0.StartPos, iv0.CurrPos, 
sum(iv1.StartPos) 'SumStartPos', sum(iv1.CurrPos) 'SumCurrPos' into 
tempdb..a_sum from  PortfolioInv iv0, PortfolioInv iv1 where iv1.ProdId 
= iv0.ProdId", select=False)


In python-sybase 0.39, the execute will activate the use of sybase 
cursors (ct_cursors) instead of commands when the request starts with 
"select".

This is done because ct_cursor is the only way I know in Sybase to 
overlap requests, for example doing an update while retrieving the 
results of a select.

The test which decide if we use a ct_cursor or not should probably be 
enriched.
