Details |
The SELECT statement selects the database items in the access descriptor to be included in the view descriptor.
The SELECT statement can take one or more of the following arguments:
ALL | includes in the view descriptor all of the items defined in the access descriptor that were not dropped. |
variable-identifier | can be the current SAS name, the
positional equivalent (which is the number that represents the item as given
by the LIST statement), or the SYSTEM 2000 component number of the database
item.
For example, if you want to select the first three items, issue the following statement: select 1 2 3; You can select as many items as you want using one SELECT statement. |
SELECT statements are cumulative within the same view creation. That is, if you submit the following two SELECT statements, items 1, 5, and 6 are selected (not just items 5 and 6):
select 1; select 5 6;
To clear all of your current selections when creating
a view descriptor, you can use the
RESET ALL
statement; you
can then use another SELECT statement to select new items.
Selecting a record selects all items within the record.
