Partitionning: support for Truncate Table WHERE

<div dir="ltr" id="divtagdefaultwrapper"
style="font-size:12pt;color:#000000;font-family:Calibri,Arial,Helvetica,sans-serif;"><p>Hello,<p><br/><p>Working in a
DSSenvironment, we often need to truncate table partitions regarding a WHERE condition and have to:<p>- query the
dictionnaryto identify thoses partitions,<p>- build SQL statements,<p><span>- truncate all partitions covered by the
WHEREcondition <br /></span><p><span>- eventually delete the rest ...</span><p>- perform additionnal maintenance
tasks<br/><p><br /><p>Wouldn't it be possible to make it possible directly in SQL as a TRUNCATE TABLE WHERE syntax ?<br
/><p>Ihave done something similar using a procedure in Oracle:<p>- identifying partitions using oracle rowids by a
SELECT usingthe same WHERE conditions<p>- for each partition check if data NOT in WHERE condition<p>- then DELETE WHERE
orTRUNCATE PARTITION depending of data distribution. <br /><p><br /><p><br /><p>Maybe there are some other constrainst
likelocking, FK disabling/enabling, indexes rebuild ...<p><br /><p>Would be pleased to ear your feedback regarding
this.<p><br/><p>Regards<p>PAscal<br /></div>
