Re: general question about naming conventions
Mark You'll get a lot of differing opinions on this subject... here are my preferences: 1) Name the table, itself, as singular - makes the SQL statements more readable (English-like) Event instead of Events, Category instead of Categories, etc. 3) Make the column names as concise and descriptive as possible ProgramID, Description, LastName, CreditCardNumber 4) Underscores and/or Caps are a personal preference 5) Do *Not* include any repetition of the table name in the column name, except: The Primary Key contains its Table name A Foreign Key Contains its Table name Department DepartmentID Integer Identity Primary Key, Name Phone AnnualBudget Employee EmployeeID Integer Identity Primary Key, DepartmentID References Department Name Phone Salary 6) Do *not* include, in the column name, any reference to the type of field: int, char, text, etc. It is not unusual for field types to be changed over time, for example a varchar field is changed to a text field. Why make the programmer change all his programs, documentation, operating procedures, etc., *just* because the field *type* has changed? 7) When you reference a column, use the table name as a qualifier. This makes a concise, readable query: SELECT Employee.Name, Employee.Phone, Employee.Salary, Department.Name, Department.Phone FROM Employee LEFT OUTER JOIN Department ON Employee.DepartmentID = Department.DepartmentID As opposed to: SELECT Emp_chr_Name, Emp_chr_Phone, Emp_mon_Salary, Dep_chr_Name, Dep_chr_Phone FROM Employee LEFT OUTER JOIN Department ON Emp_fk_DepartmentID = Dep_pk_DepartmentID I use the above conventions and have found them to yield efficient and readable code (and documentation). The readability is especially important for use by lay people when creating Ad Hoc queries/reports or communicating their needs to programmers... the database becomes a major asset of the *entire* enterprise.

RE: general question about naming conventions
We assign every table in all databases a unique 3 character prefix. Then our columns would be prefixed with that. For your example I might assign the prefix evt so the columns become evt_Start, evt_End, evt_Info. This helps in that you can then reference fields and not have to worry about the uniqueness of the name. For example, every table of ours has an identity column. We would call this field evt_id and in another table maybe evd_id. Then I could say: SELECT evt_id, evt_somedata, evd_id, evd_otherdata FROM events LEFT OUTER JOIN eventdetail ON evt_id = evd_evt_id WHERE evt_somefield = 'some data' Hope this helped. __ Bill Grover Supervisor IS DepartmentPhone: 301.424.3300 x396 EU Services, Inc.

RE: general question about naming conventions
This is something that tends to come down to personal preference everytime and is different with dang near every developer. What I like for DBs is the table name, events and then the column name and type them if possible for ease of use. So you could have Table name: Events Columns: events_ID, events_dtStart, events_dtEnd, events_info, event_bOutside Or Columns: eventsID, dtEventStart, dtEventsEnd, eventsInfo, bEventsOutside This can depend on if you want the underscores for readability or not. Without the underscores it tends to be easier to read with the type then in front of the whole field. Just my two cents, t ** Tyler M.

RE: general question about naming conventions
Mark Smeets asked:
When dealing with databases, how do you name your columns?
Personally, I use the following structure, but I don't really have any
rationale for it.
foo_id int
foo_dt datetime
foo_d date
is_foo boolean
foo_tx string (could be char, or varchar, I don't make the
distinction)
foo_desc text/memo
foo_dblfloat/double
db_foo_dt A (datetime) var that is managed by the SQL server
the user never sees (like db_updated_dt)
db_foo_by A userid that is managed by the server. (db_created_by)
Okay, maybe a little rationale:
1. I *hate* Hungarian notation. (If I'm thinking of the right term? The
one where it's like intFoo, boolBar, lpszWTF etc.)
2. I'm a big fan of StudlyCaps for variables in my CF and Perl scripts, but
I don't think that translates well to SQL. Problem being, SQL is
case-insensitive. (Yeah, technically so is CF, but I can dream.) So, while
EVENTID and eventid are readable, they aren't optimal. And I use too
many different SQL utilities, some that uppercase, some that lowercase.
Hence, my usage of long_drawn_out_underscore. Also, I tend to have several
fields in my tables of the same base name but different type. (bar_id for
the UID, bar_tx for the title, bar_desc for the details) I assume it's a
holdover from my OOP days with polymorphism and all that.
Now, having said all that, I'm going to flip it all on its head and tell you
that I don't keep that naming convention in my CF. As I said, I prefer
StudlyCaps for my CF, so I always use the AS keyword to rename my fields in
my SQL queries:
SELECT baz_id AS BazID, baz_tx AS Baz, baz_desc AS Description
FROM baz
WHERE (baz_dt {d '2001-11-12'})
This makes the query variables play nicely with the non-query variables.
(And, as you can see, I uppercase all of my SQL keywords to help distinguish
them from the non-keywords.) There's nothing more visually jarring for me
than seeing something like ThisQuery.some_bar_id in CF code. As you can
see, the translation between field name and variable name isn't exact, but
the rules are pretty simple:
quux_id- QuuxID
quux_dt- QuuxDate
quux_tx- Quux
quux_desc - QuuxDesc (or, if there is just one, Description)
is_quux- IsQuux
quux_dbl - QuuxDbl or QuuxFloat or QuuxCalc or CalcQuux
db_quux_?? - {nothing: these are manipulated within SQL}
I'm really just going for maximum faux/quasi-English readability here. For
some reason, underscore works for me for SQL, but StudlyCaps is more
readable in CF. I dunno why. That, and underscore is okay for things you
only type once or twice in a SQL statement here and there in the code, but
putting all those underscores in variables that you use line after line ...
shudder
And while I've completely gone off on a tangent, I'll just finish out my CF
coding style conventions. Here are my 12 Days of CF Coding Rules (in no
particular order):
1. My first tag in every page, with no exception, is:
CFSETTING ENABLECFOUTPUTONLY=Yes SHOWDEBUGOUTPUT=No
2. All CF tags and keywords (IS, EQ, LT), but not variables, are always
uppercased, as are HTML tags. (I started this long before XHTML lowercased
everything, and I haven't switched yet.) I find it helps me distinguish the
logic from the content. (I never uppercase entire words or phrases in
English. Too many years on IRC.) CF function names are also in StudlyCaps.
3. CGI variables and constants are always all uppercase. (Because CGI
variables are technically constants.)
4. I use This as a prefix for local variables that get overwritten a lot.
ThisID, ThisName, ThisThing.
5. I use My as a prefix for module-level variables. MyAttributeThing.
6. I try to not use single-letter variables (i, j, k) except as throw-away
local loop variables. Everything else is StudlyCaps and descriptive.
7. Avoid Evaluate() at all costs. Structures are bloody furiously useful.
8. The IS comparator is for strings, the EQ comparator is for numbers.
9. Never write in six lines of functions and assignments what you can do in
one:
Avg=ArraySum(ListToArray(ValueList(Employees.Salary)))/Employees.RecordCount
10. When in doubt, add more parenthesis. (Especially in SQL WHERE clauses.)
11. Scalar vars are singular. Array, list, and query variables are plural.
ThisDate, MyDates[i].
12. My last tag in every page is:
CFSETTING ENABLECFOUTPUTONLY=No
So, that's my style. There ya go. HTH.
