How to check if a database connection is open? @GustavoDelfino I'm afraid DatabaseLink is no different from most other database client protocols: an "open" connection does not imply a "usable" connection. The only way to know whether a database connection is still alive (as opposed to merely open) is to attempt to perform an operation on it. The common practice is to attempt a trivial query like SELECT 1 (or SELECT 1 FROM DUAL in Oraclespeak). |

Map-Thread-Through-Apply a list of functions onto a list of (lists of) values @J.M. I think it might be obsolete because it feels somewhat misnamed. A shame, because it is squatting on a decent shorter name for Composition -- a mistake I still make from time to time when writing code. The semantics of Compose are also a bit of a mixed bag: part Lisp funcall and part Composition. The former meaning (#@##2&) is what people are using for this question, and I wouldn't mind seeing another name given to that -- much like Identity is a name for #&. Call perhaps, or the lengthy FunctionCall? |

How to match expressions with a repeating pattern @Mr.Wizard Thanks for the +1. I thought twice about writing this response for those reasons. But I finally decided that //. was a legitimate strategy -- even without all of the elaborations as I suspect that neither extra replacements nor evaluation leakage are likely to cause problems in practice. I suppose it depends whether the requirement arises in library code or in a specific application with inputs of known form. I'd say I'm fond of YAGNI, but I guess this post testifies against me :) |
