FIND
Other versions: 7.31 | 7.40 | 7.54
Syntax
FIND [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern
IN [section_of] dobj
[IN {CHARACTER|BYTE} MODE]
[find_options].
Extras
1. ... {FIRST OCCURRENCE}|{ALL OCCURRENCES} OF
2. ... [IN {CHARACTER|BYTE} MODE]
Effect
The operand dobj is searched for the character or byte sequence specified by the search string pattern.
The additions FIRST OCCURRENCE and ALL OCCURRENCES
determine whether all occurrences or only the first one is searched. The addition
section_of can be used to restrict the search range. The search is terminated
if the search pattern was found for the first time, or if all search patterns were found in the entire
search area, or if the end of the search area was reached. The search result is communicated by setting
sy-subrc. The addition MODE determines a character
or byte string is processed, and the addition find_options provides additional options for controlling and analyzing the statement.
When a character string is processed, dobj is a
character-like expression
position and for dobj operands of a fixed length, the blank characters are taken into account.
System Fields
| sy-subrc | Meaning |
|---|---|
| 0 | The search pattern was found at least once in the search range. |
| 4 | The search pattern was not found in the search range. |
| 8 | The search string contains an invalid double-byte character in character string processing. |
Notes
-
The statement
FIND IN TABLEis available for searching in internal tables. -
To search in a string in an operand position, you can use search functions. They mask part of the functionality of the
FINDstatement. -
The statement
FINDand the search functions can be quicker than the comparison operatorCSby some magnitude.
Addition 1
... {FIRST OCCURRENCE}|{ALL OCCURRENCES} OF
Effect
The optional addition {FIRST OCCURRENCE}|{ALL OCCURRENCES} OF defines whether
all or only the first occurrence of the search pattern is searched. If the addition FIRST
OCCURRENCE or none of the additions is specified, only the first occurrence is found. Otherwise, all occurrences are found.
If substring is an empty string in the
pattern or is of type c, d, n,
or t and only contains blank characters, when searching for the first occurrence,
the space in front of the first character or byte of the search range is found. If searching for all occurrences, in this case the exception CX_SY_FIND_INFINITE_LOOP is triggered.
If regex contains a regular expression in the
pattern that matches
the empty character string, the search for one occurrence also finds the space before the first character.
When searching for all occurrences, in this case, the search finds the space before the first character, all intermediate spaces that are not within a match, and the space after the last character.
Addition 2
... IN {CHARACTER|BYTE} MODE
Effect
The optional IN {CHARACTER|BYTE} MODE addition determines whether
character string or byte string processing
is carried out. If the addition is not specified, character string processing is carried out. Depending
on the processing type, dobj and substring in pattern must be character-like or byte-like. If
regular expressions are used in pattern, only character string processing is permitted.
Exceptions
Catchable Exceptions
CX_SY_FIND_INFINITE_LOOP
-
Cause: Substring of length 0 generates an endless loop when searching for all occurrences.
Runtime Error:FIND_INFINITE_LOOP
CX_SY_RANGE_OUT_OF_BOUNDS
-
Cause: Illegal offset or length specification in the addition of
SECTION OF.
Runtime Error:REFI_WRONG_SECTION
CX_SY_INVALID_REGEX
-
Cause: Illegal expression after the addition
REGEX.
Runtime Error:INVALID_REGEX
CX_SY_REGEX_TOO_COMPLEX
-
Cause: More information: Exceptions in Regular Expressions.
Runtime Error:REGEX_TOO_COMPLEX
