[TRAFODION-2375]ODBC:SQLGetDiagRec return wrong msg length when data
truncate
Acoording to ODBC reference, in function SQLGetDiagRec, param
_TextLengthPtr_ should point to a buffer in which to return the total number
of characters, but it returns number of truncated characters when param
_BufferLength_ is smaller than character number of error message text.
Thus, modifications are made relating to win/unix odbc driver code as
following:
Unix ODBC: if truncation occurs, return SQL_SUCCESS_WITH_INFO, and set
variable strLen as total number of error message text whenever data is
truncated.
Windows ODBC: set variable strLen as total number of error message text
whenever data is truncated.
