Hey everybody,
can anyone provide an approach to extract the nth appearance of a
search string within a string!?
e.g: instr('test H2 database test', 'e', 1, 2) would return 16; the
second occurrence of 'e'
H2: INSTR(string, searchString, [, startInt])
possible parameter: [, nth_appearance] of searchString
see also occurance:
