◆ casedn

my_charset_conv_case MY_CHARSET_HANDLER::casedn

◆ casedn_str

size_t(* MY_CHARSET_HANDLER::casedn_str) (const CHARSET_INFO *, char *)

◆ caseup

◆ charpos

size_t(* MY_CHARSET_HANDLER::charpos) (const CHARSET_INFO *, const char *b, const char *e, size_t pos)

Return at which byte codepoint number "pos" begins, relative to the start of the string.

If the string is shorter than or is exactly "pos" codepoints long, returns a value equal or greater to (e-b).

◆ lengthsp

size_t(* MY_CHARSET_HANDLER::lengthsp) (const CHARSET_INFO *, const char *ptr, size_t length)

Given a pointer and a length in bytes, returns a new length in bytes where all trailing space characters are stripped.

This holds even for NO PAD collations.

Exception: The "binary" collation, which is used behind-the-scenes to implement the BINARY type (by mapping it to CHAR(n) COLLATE "binary"), returns just the length back with no stripping. It's done that way so that Field_string (implementing CHAR(n)) returns the full padded width on read (as opposed to a normal CHAR, where we usually strip the spaces on read), but it's suboptimal, since lengthsp() is also used in a number of other places, e.g. stripping trailing spaces from enum values given in by the user. If you call this function, be aware of this special exception and consider the implications.
