- charlen, dbmaxlen, numofchar, strlen
These built-in length functions have an unnamed character-like argument.
... func( arg ) ...
Effect
The following table shows the length functions with an unnamed argument. The arguments arg of all length functions except dbmaxlen are character-like expression positions. The argument of dbmaxlen is a character-like functional operand position. The return value has the type i for all length functions.
| Function func | Return Value |
| charlen | Length of the first character of arg in the code page used: 1 for a single Unicode character; 2 for surrogate pairs. |
| dbmaxlen | Maximum length of a string defined in the ABAP Dictionary (RAWSTRING, SSTRING, STRING, or GEOM_EWKB). If the string is unrestricted, the constant abap_max_db_string_ln or abap_max_db_rawstring_ln from the type pool ABAP is returned. The latter is also returned for the built-in ABAP types string and xstring. |
| numofchar | Number of characters in arg, where trailing blanks are neither counted in data objects with fixed lengths nor in data objects with the type string. |
| strlen | Number of characters in arg, where trailing blanks in data objects with fixed lengths are not counted, whereas in data objects with the type string they are. |
Note
The functions listed here are some of the functions that can also be used in the obsolete extended functional operand positions if their argument is a single data object.
Example
The results of the following length determinations are 10 and 5.
Example
The result of function strlen is 2 because ABAP handles the surrogate pair in the character string as two UCS-2 characters. When counting with a regular expression in PCRE syntax that is introduced with (*UTF), the result is 1, because the surrogate pair is interpreted as one UTF-16 character.
