<div><p>For DB2<sup>®</sup> Multisystem,
|
||
|
|
all instances of special registers are resolved on the coordinator node before
|
||
|
|
sending the query to the remote nodes. (A <em>coordinator node</em> is
|
||
|
|
the system on which the query was initiated.) This way, all nodes run the
|
||
|
|
query with consistent special register values.</p>
|
||
|
|
<p>The following rules are about special registers:</p>
|
||
|
|
<ul><li>CURRENT SERVER always returns the relational database name of the coordinator
|
||
|
|
node.</li>
|
||
|
|
<li>The USER special register returns the user profile that is running the
|
||
|
|
job on the coordinator node.</li>
|
||
|
|
<li>CURRENT DATE, CURRENT TIME, and CURRENT TIMESTAMP are from the time-of-day
|
||
|
|
clock at the coordinator node.</li>
|
||
|
|
<li>CURRENT TIMEZONE is the value of the system value QUTCOFFSET at the coordinator
|
||
|
|
node.</li>
|
||
|
