[sqlalchemy] Re: Stored procedures

[Ezio Vernacotola]

with  firebird engine I have to write:         this_sql = myengine.text("select * from my_procedure(:field1, :field2, :field3)",                     bindparams=[                         bindparam('field1', value=100),                         bindparam('field2', value=200),                         bindparam('field3', value=300)]                         ) this don't works:     this_sql = select([func.my_procedure(100, 200, 300)],  engine = myengine) because the generated query lacks the "*" between "select" and "from" There is a way to fix this in firebird.py ? Thanks Ezio Michael Bayer wrote: the "func" keyword is used for stored procedures. in the latest trunk, you can also create table-like elements out of funcs to support multi-column stored procedures, and you can create the SQL corresponding to the patterns you describe. however, these patterns were worked out for Postgres users...MySQL doesnt really support this (i didnt even know it had custom functions at all?). SA is only issuing SQL to the database and cant do anything that you couldnt do at a MySQL command line, for example.

If it makes a difference, I'm specifically interested in MySQL stored procedures. What I want to do is use this result set as part of another query, but MySQL doesn't currently allow treating a stored procedure as a (temporary) table, e.g. the following doesn't work: Select y from (call my_proc(1,2)) where x>3; If I can capture the result set of my_proc with sqlalchemy, I can express the outer query in python and bypass MySQL's lack of syntactic support for this. Otherwise I'll probably rewrite my_proc in sqlalchemy, which may not be that bad after all, but I'd rather avoid this if possible. Thanks, George -- Ing.
