Tuning the DUAL table

there is an article that some of the regulars here wrote, but I don't remember who did, nor do i have a link.

we have a function that basicly does this: (first name last name to lastname firstname)

SELECT CONCAT(SUBSTR(:b1,0,(INSTR(:b1,',') + 2 )),'.') FROM DUAL and it's 5gets per execution (a couple of million times per day)

can somebody point to the article?

thanks.
