Re: [sqlalchemy] Syntax error from sqlalchemy generated sql to sybase ase
That makes sense, and as much as I would volunteer to try to maintain the dialect, I can't see justify using work resources (where I have access to Sybase) to maintain an open source component for a DB we are working to migrate away from. Since the metadata is collecting ok, minus some type catches I have to do to write to other DB's, I can maybe just write raw SQL through sql alchemy or worst case through pyodbc to deal with collecting the records. Thank you for the help.

Re: [sqlalchemy] Syntax error from sqlalchemy generated sql to sybase ase
Hi there -
Unfortuantely, the Sybase dialect is unmaintained and will likely be
removed from a future SQLAlchemy release.For this database to be
usable, a dedicated maintainer would need to volunteer and we can set
them up with a new sybase ASE dialect available as a third party
download. The demand for this database is extremely low, the Python
drivers are poorly maintained and the database itself is extremely
difficult to run for testing purposes.

metadata works fine, writing to target db structure from meta works fine,
but selecting the records leads to that.

This fails on both linux (using FreeTDS version set to 5) and windows
(using the dsn name for the actual ASE driver setup in my odbc)
I am confused what is going on here that causes sybase to see this as a
syntax error.

Re: [sqlalchemy] JSON Support for mssql 2016
OK, take a look at that SQLite commit, where someone else added the exact same thing for SQLite: https://github.com/sqlalchemy/sqlalchemy/commit/62d59088dfe86d7ecabd85ad626ee108b668acc5 the feature for SQL server would look similar, although I've taken a look at https://docs.microsoft.com/en-us/sql/relational-databases/json/json-data-sql-server?view=sql-server-2017 and it looks like they don't have a JSON datatype explicitly, just JSON functions. we can still work with that but it might be a little different. if you can run tests and stuff, that would be even better, see https://github.com/sqlalchemy/sqlalchemy/blob/master/README.unittests.rst for the basic idea of that. I've created an issue to track the effort at https://github.com/sqlalchemy/sqlalchemy/issues/4384 On Wed, Nov 28, 2018 at 1:18 PM sanjeev kumar wrote: > > I was looking for sql expression support but i didn’t find anything,so random > thought came why can’t contribute to. > So if u give me any idea, to start things it will be very great > > -- > SQLAlchemy - > The Python SQL Toolkit and Object Relational Mapper > > http://www.sqlalchemy.org/ > > To post example code, please provide an MCVE: Minimal, Complete, and > Verifiable Example.

I was looking for sql expression support but i didn’t find anything,so random thought came why can’t contribute to.

Re: [sqlalchemy] JSON Support for mssql 2016
this can be contributed. the basic idea can be emulated from the SQLite version of the type, given in this change: https://github.com/sqlalchemy/sqlalchemy/commit/62d59088dfe86d7ecabd85ad626ee108b668acc5 note the main reason you'd want to make a JSON type is because you need the SQL expression support, like table.c.mycolumn['foo'] == 'bar'. if you just need to persist and load JSON, a simple UserDefinedType https://docs.sqlalchemy.org/en/latest/core/custom_types.html?highlight=userdefinedtype#creating-new-types can get you that.the main thing to determine is if the driver you're using, eg. pyodbc or pymssql, supports JSON natively, or if you need to be doing the loads() / dumps() explicitly. To sum up, two questions: 1. do you need SQL expression support (or are you just looking to contribute to SQLAlchemy in any case, in case, great!), or do you just need to store and retrieve JSON objects right now. 2. do pyodbc/pymssql support JSON or do we have to send/receive strings that we convert ourselves. from those questions we can figure out the best strategy.
