Обсуждение: Invalid Blob length
I am using a BDE connection from a windows app I'm building to connect to Postgres 7.3.2 running on Redhat on a linux box.
When I attempt to Post the dataset which I have loaded with a very large 'text' string, I get the following error: Invalid Blob length.
The field on the table is a type 'text'. The string that I am loading to the database is about 4,000 ascii characters long. (not really that large).
Any ideas as to why I am getting this error? Is there a setting I need to change on the database?
Thanks for your help,
Derrick
I think I've heard of this before... I don't know what BDE is, but I heard about a problem with ODBC and blobs over 500 bytes long. It came down to the ODBC driver of course. That was a year ago, I don't know if it ever got fixed.
I hope that helps.

I don't know about BDE but the ODBC driver for postgres limits large text to about 500 characters by default. That can be changed via the properties in the ODBC connection settings. Maybe BDE does something similiar. You might try searching the pgsql-odbc mailing list.
