Undocumented SQL Server-style
SMALLDATETIME,DATETIME, andDATETIME2data types are restricted to Legacy and MSSQLServer compatibility mode. If some application misuses them in other compatibility modes,Mode.datetimeTypescan be set totrueas a workaround. Their fractional seconds precision is also corrected to be more compatible with the real SQL Server.DATETIMEOFFSETdata type can now be used in MSSQLServer compatibility mode. As usual, it is mapped to standard data type in the parser. Closes #4179.
