Hi,

I get on OutOfMemoryException while trying to migrate data from postgres to SqlServer 2008 with a big table (+8millions of rows):
The error message is :
- Pre-execute (Error)

I've found a similar post in the forum in 2007 but the problem seems to come again :

I'm using dcpostgresql65pro

Thanks

Thank you for your report. We will investigate the issue and notify you about the result as soon as possible.

The Default FetchAll connection string parameter for defining default value of the FetchAll property of PgSqlCommand objects created on the connection is implemented. We will post here when the corresponding build of dotConnect for PostgreSQL is available for download.

The "Default FetchAll=false;" connection string setting with the upcoming build should fix the System.OutOfMemoryException problem.

Thanks,

Is there a workaround to specify the FetchAll setting in the the DTS ?

We are going to release the new public build of dotConnect for PostgreSQL with the Default FetchAll connection string parameter this week. We will post here when it is available for download.

New build of dotConnect for PostgreSQL 6.7.301 is available for download now!
It can be downloaded from http://www.devart.com/dotconnect/postgr ... nload.html (trial version) or from Registered Users' Area (for users with active subscription only).
