Sybase optional output parameter dictionary



What do other database adaptors do about stored procedure return values? The control is returned to the calling routine. Making the transaction-handling statements a part of the client code serves a two-fold purpose; the server code is more portable, and the distributed transactions can be independent of the server code.

Skip Montanaro I've stumbled on a problem with the python-sybase module. Currently, the python-sybase module provides I believe the ability to set output parameters those specified as such in the argument dictionaryand you can iterate over all the result sets the stored procedure produces. Looking at the Python database API PEPI saw no mention of the return status:.

The sequence of parameters must contain one entry for each argument that the procedure expects. The result of the call is returned as modified copy of the input sequence. The procedure may also provide a result set as output. This must then be made available through the standard. I see no mention of how to handle the return value. The "modified copy of the input sequence" is just that. In the case of the paramefer module, any parameter values optipnal the input dictionary of type DataBufType are rewritten with values from the first row of the first result set.

I haven't had a chance to try it out yet. My concern is more that the Python database API doesn't mention stored procedure return values at all. What do other database adaptors do about stored procedure return values? Does PEP need revision? All Groups Python python-list. NUMBER As a general solution, one might wrap a stored procedure that returns a value into a stored procedure that has an output parameter and call it with callproc. Some implementations might include a return value in.

John Gordon That will get the return value into an SQL variable, but the OP wanted to know how to fetch it from python code.

Skip Montanaro Thanks for the responses. We eventually figured out there appears to be a bug in the latest version of the python-sybase module at least in 0. Testing a fix now. Thanks for the responses. Chris Angelico In forex account opening india drought, that should produce a one-row-one-column SELECT result, which can then be retrieved as such. I say "in theory" because not all back-end databases support the "from dual" notation - which, by the way, I find extremely odd; what's 'dual' about it?

Most other servers allow SELECT without FROM.

I don't remember what DB2 has. MySQL I think requires either DUAL or an actual real table. On Zybase, Mar 14, at AM, wrote: DUAL is an Oracle thing.
