'123-987-123' it is not fixed some times it may be '1233-9873-123-098'
as you said it's fixed,
changes the values in middle of the -
sometimes times i need 1233 and 098 or 9873,first position i'll find direct for second variable we don't know where it's end with -
i.e ,
i need to find second postition of the variable between the '-'
While I and others are likely inclined to provide you a working solution to do so you need to state your data and requirement more clearly. Given the apparent language dynamic I'd suggest supplying 5-10 example data values along with their expected result.
Otherwise, regular expressions almost certainly will let you solve your problem (though, like Joe Conway indicated, split_part may be possible) once you learn how to construct them. regexp_matches(...) is the access point to using them.
