second call for a better name
Hello everyone,
any idea for a better name than DataMode for our new enum anyone?
The requirements are:
- The enum contains the items ReadOnly, Nullable (or Optional), NotNull (or Required), AutoGenerated
- The name should be short (<=8) to keep data definitions small
- It should be understandable.
How about:
- Mode
- Modifier
- Mod (short for Modifier)
- (just) M
- Def
- Xtra
- X
- Claim (would semantically be right but sounds odd, doesn't it?)
Here is an example of where it is used (see DataMode...):
DEPARTMENT_ID = addColumn("DEPARTMENT_ID", DataType.AUTOINC, 0, DataMode.AutoGenerated, "DEP_ID_SEQUENCE");
NAME = addColumn("NAME", DataType.TEXT, 80, DataMode.NotNull);
HEAD = addColumn("HEAD", DataType.TEXT, 80, DataMode.Nullable);
BUSINESS_UNIT = addColumn("BUSINESS_UNIT", DataType.TEXT, 4, DataMode.NotNull, "ITTK");
UPDATE_TIMESTAMP= addColumn("UPDATE_TIMESTAMP", DataType.DATETIME, 0, DataMode.AutoGenerated);
Looking forward for your responses.
Regards
Rainer

They are not really different things but correlated. Nullable and NotNull are only valid for updateable fields. ReadOnly and AutoGenerated columns are not updateable (this question here is whether we really need both of them).
ReadOnly may not be used for Tables (only for views and beans).

This somehow sounds as putting different things into one enum... Is
this also one property in most databases?

Can't think of anything better...
