Yeah..maybe a little m ore clarification would have helped...but certainly to not use it all would be a tad harsh ;-)
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 20 July 2005 16:23 To: CF-Talk Subject: RE: CFQuery and SQLBase - alternative to using asterisk I think the point is that if you do not need ALL fields of a table, then you should specify the fields you DO need instead of using the all generic *. Say you have a table with several text, blob or other big fields, but you only need to check 3 fields in a query...using * uses alot of server overhead when unnecessary. It is generally considered 'sloppy' programming, and does have an impact on applications depending on the # of fields and field types in their databases. To say it should never be used should be replaced with "it should never be used unless you are retrieving all fields from a table" and even then, specifying the field names will be more helpful to anyone else who may come back to your code after 2 years (including yourself!) and is trying to figuer out what fields the query is pulling. Generally speaking, it is best practice to designate your fields in the SELECT statement for ease of code reading and maximum efficiency. *Whew* Dave -----Original Message----- From: Robertson-Ravo, Neil (RX) [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 20, 2005 11:04 AM To: CF-Talk Subject: RE: CFQuery and SQLBase - alternative to using asterisk That is a fairly loose statement... "your shouldn't ever...." what if there is a need? There is not founding in you stating you shouldn't ever use it. -----Original Message----- From: Al Everett [mailto:[EMAIL PROTECTED] Sent: 20 July 2005 15:50 To: CF-Talk Subject: Re: CFQuery and SQLBase - alternative to using asterisk You shouldn't ever use SELECT *. Name the columns you want. For the other, try PHONE##.
