Oracle: INSTR (str, pattern, [starting position, [nth occurrence]])Find the starting location of the nth occurrence of pattern beginning in the starting position-th position in string str. ExamplesWe use the following table for our examples. ...
LOCATE (which, as you can see, reverses the order of the first two arguments, like this: substring,string) will take a starting position argument, although not an instance argument. You could, however, use LOCATE to find all instances of a substring by using a loop that successively sets ...
