[sqlalchemy] Re: metadata reflecting all schemas
not currently ! you'd have to issue the correct SQL for that database. On Nov 30, 2008, at 4:18 AM, [EMAIL PROTECTED] wrote: any sqlalchemy ways of retrieving a list of schemas?

[sqlalchemy] Re: metadata reflecting all schemas
Or maybe this is my problem
/home/jchesney/workspace/sqlalchemy/lib/sqlalchemy/engine/base.py:
1237: SAWarning: Did not recognize type 'name' of column 'USERNAME'
self.dialect.reflecttable(conn, table, include_columns)
/home/jchesney/workspace/sqlalchemy/lib/sqlalchemy/engine/base.py:
1237: SAWarning: Did not recognize type 'name' of column 'SCHEMA_NAME'
self.dialect.reflecttable(conn, table, include_columns)
/home/jchesney/workspace/sqlalchemy/lib/sqlalchemy/engine/base.py:
1237: SAWarning: Did not recognize type 'name' of column 'TABLE_NAME'
self.dialect.reflecttable(conn, table, include_columns)
/home/jchesney/workspace/sqlalchemy/lib/sqlalchemy/engine/base.py:
1237: SAWarning: Did not recognize type 'name' of column 'FIELD_NAME'
self.dialect.reflecttable(conn, table, include_columns)
I use the 'name' column data type for my columns.
Its a postgresql database.
engine = create_engine('postgres://.')
engine
metadata = MetaData()
metadata.reflect(engine,'')
for t in metadata.tables.values():
print t.fullname
for c in t.columns:
print \t + c.name
I get a partial listing which as two different schemas in it. Is the
reflect bombing out when it hits the above errors?
If so, I will need to try and get sqlalchemy to accept this field
type.

[sqlalchemy] Re: metadata reflecting all schemas
the type is not recognized but the reflection operation should
succeed. thats why you're only getting a warning on those.

[sqlalchemy] Re: metadata reflecting all schemas
Thanks Michael
If its just a warning and its supposed to continue past it, Why
doesn't it finish reflecting all the tables in all the schemas instead
of a few tables in two schemas.
I think it retrieved all the tables in the first schema which i
specified and followed the foreign keys to retrieve the metadata for
the second tables.
Any suggestions on how i can reflect a list of schemas or make it
reflect all the schemas? it didn't like '%' as the schema name.
