I'm running DCOracle v1.3.1b with Oracle 8.1.6 (8iR2) on a W2k Server. I created a test table with only a primary key and a blob column. Then I tried to insert some test data into it with the code below: import DCOracle, sys, os, DCOracle.dbi dbc = DCOracle.Connect('user/pwd@dbname') cur = dbc.cursor() fn = open('test_img','rb') data = fn.read() fn.close() param = DCOracle.dbi.dbiRaw(data) cur.execute('insert into image_test (no, img) values(35, :p1)', param) dbc.commit() cur.close() dbc.close() The error occurs whenever 'test_img' is greater than 4000 bytes. Perhaps it has something to do with the Oracle VARCHAR2 size limit. If 'test_img' is larger than 4K, I get the following traceback: <DCOracle.dbi.dbiRaw instance at 887d60> Traceback (innermost last): File "DCOracle_test.py", line 14, in ? cur.execute('insert into image_test (no,img) values(35,:p1)',param) File "E:\site\lib\python\Products\DCOracle\ociCurs.py", line 299, in execute r = self._execute(params__, kw) File "E:\site\lib\python\Products\DCOracle\ociCurs.py", line 260, in _execute if rc!=3129: self._error() File "E:\site\lib\python\Products\DCOracle\ociCurs.py", line 109, in _error raise error, (rc, oci_.OracleErrorMessage(self._c.lda, rc)) oci.error: (3113, 'ORA-03113: end-of-file on communication channel\012') Did anyone have similar problem? Is it true that DCOracle treats all data (including blob) as string? The 4K limit seems to hint that DCOracle tries to insert my 'test_img' as varchar.
