Description The Oracle LENGTH function is used to return the length of a given string. If the string has data type CHAR, then the length includes all trailing blanks. If a string is null, then this function returns null. LENGTHB uses bytes instead of characters.
Description Length returns the length of the string or array S, which is limited to 255 for shortstrings.If the string S is empty, 0 is returned. Note: The length of the string S is stored in S for shortstrings only. The Length function should always be used on ansistrings and widestrings.
