<h1 class="topictitle1">Use the data of <span class="cmdname">RTVDIRINF</span></h1>
|
|
<div><p>Here are examples that display why the data is important or how
|
|
you can use the data that is produced from each of the three tables.</p>
|
|
<div class="section"> <ul><li>For <a href="rzaaxwwcomm.htm#rzaaxwwcomm__rzaaxstrobj">Table 1</a>, you
|
|
can make queries to create reports or statistics based on any of the fields
|
|
within this table. <span class="cmdname">PRTDIRINF</span> does not include reports based
|
|
on all of the fields. Instead, a subset will be used.</li>
|
|
<li>The data from <a href="rzaaxwwcomm.htm#rzaaxwwcomm__rzaaxstrdir">Table 2</a> contains
|
|
all the directories within the path specified in DIR parameter of the <span class="cmdname">RTVDIRINF</span> command.
|
|
If you want to know specific attributes about the path name, for example the
|
|
CCSID, language ID, or length, then this data would be useful. Also, each
|
|
directory stored in this table has a unique value, or index that identifies
|
|
it. In <a href="rzaaxwwcomm.htm#rzaaxwwcomm__rzaaxstrobj">Table 1</a>, you
|
|
can find the same field, QEZDIRIDX, that will tell you which objects belong
|
|
to which directory. To find which objects belong to which directory, you can
|
|
make a query using joins. For example, the following query statement selects
|
|
the names of all objects existing in directory "/MYDIR": <pre>SELECT QEZOBJNAM FROM library_name/QAEZxxxxO, library_name/QAEZxxxxD WHERE QEZDIRNAM1 = "/MYDIR" AND
|
|
library_name/QAEZxxxxO.QEZDIRIDX=library_name/QAEZxxxxD.QEZDIRIDX</pre>
|
|
</li>
|
|
<li><a href="rzaaxwwcomm.htm#rzaaxwwcomm__rzaaxstrfil">Table 3</a> is mostly
|
|
used by <span class="cmdname">PRTDIRINF</span> command to obtain specific data about <span class="cmdname">RTVDIRINF</span> runs.
|
|
Examples of this are: The names of the tables created, the library where the
|
|
tables reside, and the starting and ending time of processing. You might use
|
|
this table to know when a <span class="cmdname">RTVDIRINF</span> was issued or what
|
|
tables must be searched in order to query them.</li>
