SQL 1992, 9.2 GR 3 e)
"""
If the data type of T is variable-length character string and
the length in characters M of V is greater than the maximum
length in characters L of T, then,
Case:
i) If the rightmost M-L characters of V are all <space>s, then the value of T is set to the first L characters of V
and the length in characters of T is set to L.
ii) If one or more of the rightmost M-L characters of V are not <space>s, then an exception condition is raised: data
^^^^^^^^^ exception-string data, right truncation.

Similarly in SQL 1999 and for other data types.
