// Although SQL standard mandates right padding CHAR(N) values to their length
|
|
// with spaces, some backends don't confirm to it:
|
|
//
|
|
// - Firebird does pad the string but to the byte-size (not character size) of
|
|
// the column (i.e. CHAR(10) NONE is padded to 10 bytes but CHAR(10) UTF8 --
|
|
// to 40).
|
|
// - For MySql PAD_CHAR_TO_FULL_LENGTH option must be set, otherwise the value
|
|
// is trimmed.
|
|
// - SQLite never behaves correctly at all.
|
|
//
|
|
// This method will check result string from column defined as fixed char It
|
|
// will check only bytes up to the original string size. If padded string is
|
|
// bigger than expected string then all remaining chars must be spaces so if
|
|
// any non-space character is found it will fail.
