Provider for Oracle, v5.0.22
I.e. if a varchar2 column is set to a max length of 50, a string with a length bigger than 50 will just get silently truncated by EF and inserted "normally".
I have not yet tested behaviours with other datatypes.
EF provider for MSSQL will throw an exception.
This is a critical bug, as an exception is allways expected in these kind of scenarios.
