AV when querying RAW and CLOB
Posted: Wed 15 Aug 2012 16:21
I think this is related to the problem I posted yesterday, but when I query a RAW and CLOB in the same query, with Unicode enabled, and RawAsString = true, an AV is thrown. No TDataSource or TDBGrid needed.
Error is "Project1.exe raised exception class $C0000005 with message "access violation at ....: read of address ....."
Here is the call stack from Delphi. I would have sent the one from Eurekalog, but it doesn't seem right in this case.
Code: Select all
OraCall.OCIUnicode := true;
OraSession1.Options.UseUnicode := True;
OraSession1.Connected := true;
SmartQuery1.SQL.clear;
SmartQuery1.sql.add('select s.saddr, a.sql_fulltext');
SmartQuery1.sql.add('from v$session s, v$sqlarea a');
SmartQuery1.sql.add('where rownum = 1');
SmartQuery1.Options.RawAsString := true;
SmartQuery1.Active := true;Here is the call stack from Delphi. I would have sent the one from Eurekalog, but it doesn't seem right in this case.
