This all started when one of the 16 byte binary primary keys kicked out
a duplicate key error. It seems mysql does not store the last byte of
the binary value if it is a space. That is, ascii 32 or hex 20.
How do I force it to store the space? Thanks!
create table testtable ( id binary(16) NOT NULL PRIMARY KEY ) ENGINE=MyISAM;
There is no native mysql BINARY type; it's mapped to CHAR(n) BINARY.
CHARS and VARCHARS trim trailing blanks (A known issue, but low
priority I think). Try using a TINYBLOB column type instead.
I agree about using the TINYBLOB to avoid trailing space truncation, but
BINARY and VARBINARY are MySQL data types now.
