... {[SUBSTRING] sub_string} | {REGEX regex} ... .
: Definition of a search string for the statements
REPLACE and
REPLACE IN TABLE. The search can either be for a substring
sub_string or a regular expression regex. The
syntax and semantics are the same as in the definition of a search string for the statement FIND.
: A regular expression that is syntactically correct can still be too complex for the execution of the
statement REPLACE, which can lead to a treatable exception
of the class CX_SY_REGEX_TOO_COMPLEX. However, this normally only occurs for generated regular expressions.
