Improve handling of LOBs in result view (Oracle) #8
Description
When a query results contains LOBs and the number of results exceeds the visible area (so that the result view has scrollbars) an error is logged on console:
Traceback (most recent call last):
File "/home/andi/devel/runsqlrun/rsr/worksheet/results.py", line 331, in do_get_value
data = str(value)
cx_Oracle.ProgrammingError: LOB variable no longer valid after subsequent fetch
LOBs shouldn't be accessed directly when displayed in result list. Instead a simplified text version should be used.
In addition: resizing a column containing LOBs is verrry slow.
