In Oracle/PLSQL, the instr function returns the location of a sub-string in a string.

If the sub-string is not found, then instr will return 0.

I want to search multiple sub-strings in a string and return the first non-zero value. This can be achieved using regexp_instr, but I'd like a non-regexp_ solution.


regexp_instr('500 Oracle Parkway, Redwood Shores, CA','(Apple|Park|Shores)')

should return 12 (the location of 'Park').
