I think that IsError() become WasError() at some point in the history Smile

There is whole lot of well-documented error-related methods in SqlSession class:

bool WasError() const;
void SetError(String error, String stmt, int code = 0, const char * scode = NULL, Sql::ERRORCLASS clss = Sql::ERROR_UNSPECIFIED);
String GetLastError() const;
String GetErrorStatement() const;
int GetErrorCode() const;
String GetErrorCodeString() const;
Sql::ERRORCLASS GetErrorClass() const;
void ClearError();
void InstallErrorHandler(bool (*handler)(String error, String stmt, int code, const char *scode, Sql::ERRORCLASS clss));

They should solve any problem you have, at least in theory Wink
