SCALAR FUNCTION HASH8 MAY RETURN DIFFERENT RESULTS FOR THE SAME INPUT ON POWER(TM) LITTLE ENDIAN SYSTEMS
|
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
Scalar function HASH8 may return different results for the same
input on POWER(TM) little endian systems.
When the input to the HASH8 function is not an integral multiple
of 4 bytes long, repeated invocations of the function for the
same input may produce different output hash values.
This affects Db2 running on POWER(TM) little endian Linux
systems
only.
e.g.
$ db2 "select v,hash8(v) hashvalue from hash8_test"
V HASHVALUE
