Question
I'm trying to retrieve a BLOB field from Oracle and show it in a crystal report. While viewing the report, I've that error:
Failed to open a rowset.
Details: ADO Error Code: 0x
Source: Microsoft OLE DB Provider for oracle
Description: Unspecified error
I use a View as report datasource, its script
SELECT COMPANY_ID, COMPANY_LOGO FROM ID_COMPANY_SETUP;
I'm using CrystalReport embedded with VS.NET 2005.
Any suggestions?
Solution
I got where was the problem. It was "Connection Type".
I were using OLE DB(ADO) for connection to database, while I changed it to Oracle Server connection, blob field retrieved properly.
