Column and Attribute Sequence Order in Oracle Designer
(and using reserved words for attributes)
The display sequence of columns in forms and attributes in entities is
set differently than it is for columns in actual tables.
Here is the property palette of an entity (in the E/R Diagrammer)
The second column is a Sequence sort that affects how the attributes
appear on a diagram and how they will appear in a generated form.
Here, Iíve got the columns sequenced 10-90 in the
order I want them to appear.
I used a bunch of reserved words as attribute
names to show that when they are generated, some get prefixed with the
Here is the property palette of the table definition
in Design Editor (after running the DDT).
The columns displayed are in the sequence order
I set in the Entity definition.
However, when I generate the DDL to create tables,
the column order will be determined by the sequence_in_table property of
This also determines the order they show up in the
relational table definition.
Here is the Design Editor (server model tab).
The left side shows the columns in the relational
The right side shows the property palette for the
TYPE (now named resrc_type) column.
There is a Sequence in table property set to "2".
Now I have reordered the columns with the two IDs
as 1 and 2 and all the rest with the original 10-90 sequencing used in
The columns on the left have been reordered and
the property palette on the right is now for the foreign_key..
Generating the DDL gives me the fields in the order
Here is the table creation script:
