How to properly name record creation(insertion) datetime field?

If I create a table with datetime default getdate() field that is intended to keep date&time of record insertion, which name is better to use for that field ?

I like to use Created and I've seen people use DateCreated or CreateDate.

Other possible candidates that I can think of are: CreatedDate, CreateTime, TimeCreated, CreateDateTime, DateTimeCreated, RecordCreated, Inserted, InsertedDate, ...

From my point of view anything with Date inside name looks bad because it can be confused with date part in case if I have 2 fields: CreateDate,CreateTime, so I wonder if there are any specific recommendations/standards in that area based on real reasons, not just style, mood or consistency.

Of course, if there are 100 existing tables and this is table 101 then I would use same naming convention as used in those 100 tables for the sake of consistency, but this question is about first table in f开发者_StackOverflowirst database in first server in first application.

Why not just use plain on Created, or CreatedOn. Windows OS uses three date properties for files.

Created:
Modified:
Accessed:

So you could try to keep that sort of convention if you prefer.

I tend to InsertedDateTime and InsertedBy (and Updated%, Affected% for indirect updates perhaps, Deleted% for logical deletes).

OperationDateTime for general auidt table

If I was storing a date only, it would be StartDate. Likewise, time only would be BookedTime

Another rule is to avoid "SQL" terms, so Added/Changed rather then Inserted/Updated. I inherited Inserted/Updated and it's consistent at least

Just be consistent: no mixing Created% with Inserted% with Added%

I always use CreatedDate in these circumstances, and it gives a template for other dates: UpdatedDate, DeletedDate, PurchasedDate and so on.

For the name of the column in the database, I like created_at.

And for the name of the property in the object used in my code, I like createdAt.

Not sure there is any "official" way of naming that kind of field -- but that's the default name of a well-used ORM in PHP, and I've kept that convention even for projects in which I don't use that convention.

I always use these these column names:

CreateDate  --when they did it
CreateID    --who who did it

LastChgDate --when they did it
LastChgID   --who who did it

---

Windows in file properties use

DateCreated
DateModified

so I think its not bad to go with that.
