<p>An <span class="italic">alias</span> is an alternate name for a table or view.
|
||
|
|
You can use an alias to reference a table or view in those cases where an
|
||
|
|
existing table or view can be referenced.<sup class="fn"><a id="wq11" name="wq11" href="rbafzmstali.htm#wq12">3</a></sup> However,
|
||
|
|
the option of referencing a table or view by an alias is not explicitly shown
|
||
|
|
in the syntax diagrams or mentioned in the description of SQL statements.
|
||
|
|
Like tables and views, an alias may be created, dropped, and have a comment
|
||
|
|
or label associated with it. No authority is necessary to use an alias. Access
|
||
|
|
to the tables and views that are referred to by the alias, however, still
|
||
|
|
require the appropriate authorization for the current statement.</p>
|
||
|
|
<p>An alias has a name and may have a different system name. The system name
|
||
|
|
is the name used by i5/OS. Either name is acceptable wherever an <span class="italic">alias-name</span> is specified in SQL statements.</p>
|
||
|
|
<p>An <span class="italic">alias</span> is created with the CREATE ALIAS statement.
|
||
|
|
For more information about creating aliases, see <a href="rbafzmsthcalias.htm#hcalias">CREATE ALIAS</a>.</p>

<div class="fntext">You cannot use an alias in all

contexts. For example, an alias that refers to an individual member of a database
|
||
|
|
file cannot be used in data definition language (DDL) statements.</div>
