|
|
<div><p>You can specify the sort sequence in the iSeries™ Access functions. When performing
|
|
queries on the server databases and SQL tables, you can specify the system-supplied
|
|
or user-supplied sort sequence tables.</p>
|
|
<div class="section" id="rbagspcsc3__Header_411"><a name="rbagspcsc3__Header_411"><!-- --></a><h4 class="sectiontitle">Remote SQL support</h4><p>You can specify
|
|
the way the selected data has to be sorted when performing the query. For
|
|
that purpose, sort fields must be specified in the ORDER BY clause. The following
|
|
clauses also use the specified sort sequence:</p>
|
|
<ul><li>WHERE clause</li>
|
|
<li>GROUP BY clause</li>
|
|
<li>HAVING clause</li>
|
|
<li>JOIN BY clause</li>

<li>RANGE predicate</li>

<li>MAX function</li>
|

<li>MIN function</li>

<p>The actual sort sequence table is retrieved from the job attributes
|

of the user. The SRTSEQ and LANGID parameters can be affected through changing
|
|
the user profile or changing the job attributes.</p>

operations:</p>
