i designed a report in crystal reports for visual studio 2008 with Oracle 11g Database. In my stored procedure i have 2 columns of BLOB Data type (for logo) and i connected it using Microsoft OLE DB Provider for Oracle.
when i removed the BLOB columns, then the stored procedure gets added to the report.
when i not removed the BLOB columns, then exception occurs at the time of passing the values to the input parameter of the report.
