I have an Microsoft SQL Server IS job that has been running in production for several years. It pulls data
from a PostgreSQL 8.4.2 database on Linux into an SQL Server 2005 installation on Windows Server 2003 (all 32-bit). I am re-writing this in a test environment that consists of the same PostgreSQL database and an SQL Server 2008R2 installation on Windows
Server 2008R2 (all 64-bit). On the Windows Server 2008R2 machine, I installed 64 bit Postgres ODBC drivers and found that I could not see
them when creating an ADO.net connection manager in BIDS. A bit of googling later, I removed the 64 bit drivers and installed 32-bit Postgres ODBC drivers and set up DSNs usning windows\SysWOW64\odbcad32.exe. When setting up the DSNs, clicking the test button
returned 'Connection successful'. Back to BIDS, create a new ADO.net connection manager, ODBC Data Provider, select the DSN name in 'Use user
or system data source name', hit the test connection button. It returns 'Test connection succeeded'. Create a data flow task, edit, add an ADO.NET source, edit, select the new connection manager, Data access mode is set to 'Table or view', click the drop
down for 'Name of the table or view:', it says loading and will sit there like that forever. If I click it again, it returns the following error message: 'Could not retrieve the table information for the connection manager 'PostgreSQL30'. Object reference not set
to an instance of an object. (Microsoft.DataWarehouse)' If I select 'SQL Command' as the Data Access mode, and enter any SQL Command (eg select * from PostgresTable)
and hit the Preview button, the expected data is returned. My question is why can it not return the list of tables, but it can return data. Any help would be appreciated. Rick Bailey Database Specialist Materials Research Institute 123 Land & Water Building University Park, PA 16802 814-863-1294 |
