# FixedString(N)
|
|
|
|
A fixed-length string of N bytes (not characters or code points). N must be a strictly positive natural number.
|
|
When the server reads a string that contains fewer bytes (such as when parsing INSERT data), the string is padded to N bytes by appending null bytes at the right.
|
|
When the server reads a string that contains more bytes, an error message is returned.
|
|
When the server writes a string (such as when outputting the result of a SELECT query), null bytes are not trimmed off of the end of the string, but are output.
|
|
Note that this behavior differs from MySQL behavior for the CHAR type (where strings are padded with spaces, and the spaces are removed for output).
|
|
|
|
Fewer functions can work with the FixedString(N) type than with String, so it is less convenient to use.
