I have been trying to insert HTML files into BLOB column using JDBC. About 90% of the HTML files are inserted correctly, but it seems to me that rest of the HTML files are not inserted. Those HTML files are not big enough to fail. While others return correct file size with a stored procedure, some return nothing. If BLOB columns are not updated and still have emply_blob(), that stored procedure should return 0 instead. Why those blob columns are not updated correctly? Please somebody help me!
