error retrieving null value from a driverResultSet with getString
-----------------------------------------------------------------
Key: CAROB-47
URL: https://forge.continuent.org/jira/browse/CAROB-47
Project: Carob
Type: Bug
Components: C++ API
Environment: Paldo linux x86
IBM laptop R51 - 512MB memory
Sequoia 2.4 beta - backend mysql 5.0
Reporter: Zsolt Simon
Assigned to: Gilles Rayrat
Priority: Minor
When executing the above specified commands, an exception is thrown:
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct NULL not valid
The code fragment where this happening:
wstring DriverResultSet::getString(int32_t columnIndex) throw (SQLException,
UnexpectedException)
{
checkRowAndColPosAndSetNullFlag(columnIndex);
if (wasNullFlag)
return NULL; <---- exception is thrown here
wstring can't be initialized with NULL.
Needs another logic for this function to signal NULL values.
