Hi All,
I have a big set of queries provided as raw sql like:
"""
SELECT somestuff FROM somewhere
WHERE some_date >= :from_date AND some_date <= :to_date
"""
That's fine, I just blat it at session.execute and provide from_date and
to_date in the params dict.
However, they now wany to supply something like:
"""
SELECT somestuff FROM somewhere
WHERE some_date >= :from_date AND some_date <= :to_date
AND somefield in :values
"""
Now, I have values as a sequence of strings that I need to provide,
but supplying in the params dict_ doesn't work:
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/orm/session.py",
line 753, in execute
clause, params or {})
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/engine/base.py",
line 824, in execute
return Connection.executors[c](self, object, multiparams, params)
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/engine/base.py",
line 874, in _execute_clauseelement
return self.__execute_context(context)
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/engine/base.py",
line 896, in __execute_context
self._cursor_execute(context.cursor, context.statement,
context.parameters[0], context=context)
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/engine/base.py",
line 950, in _cursor_execute
self._handle_dbapi_exception(e, statement, parameters, cursor, context)
File
"/usr/lib/python2.5/site-packages/SQLAlchemy-0.5.8-py2.5.egg/sqlalchemy/engine/base.py",
line 931, in _handle_dbapi_exception
raise exc.DBAPIError.instance(statement, parameters, e,
connection_invalidated=is_disconnect)
sqlalchemy.exc.OperationalError: (OperationalError) near "?": syntax
error u'AND somefield in ?' [('1', '2', '3')]
What should I do?
cheers,
Chris
