LIKE differs from the regular comparison operator ('=') in the following:
|

- LIKE never ignores trailing spaces (even for PAD SPACE collations)
|
||||
Propagation of equal fields with a PAD SPACE collation into LIKE
|
||||
is not safe.
|
||||
Example:
|
||||
WHERE a='a ' AND a LIKE 'a' - returns true for 'a'
|
||||
cannot be rewritten to:
|
||||
WHERE a='a ' AND 'a ' LIKE 'a' - returns false for 'a'
|
||||
Note, binary collations in MySQL/MariaDB, e.g. latin1_bin,
|
||||
still have the PAD SPACE attribute and ignore trailing spaces!
|
||||
- LIKE does not take into account contractions, expansions,
|
||||
and ignorable characters.
|
||||
Propagation of equal fields with contractions/expansions/ignorables
|
||||
is also not safe.
|
||||
|
||||
It's safe to propagate my_charset_bin (BINARY/VARBINARY/BLOB) values,
|
||||
because they do not ignore trailing spaces and have one-to-one mapping
|
||||
between a string and its weights.
