Hello all,<br /><br />I have a custom code written inside postgres in an application we use.<br />The snippet is as
below:<br />Here inner plan is an index scan.<br /><br /> scandesc = ((IndexScanState *)innerPlan)->iss_ScanDesc;
<br/><br /> flag=index_getmulti(scandesc, &tidelm->tid, 1, &ret_tids);<br /><br />Now consider a query
like<br/><br />explain select * from dept,manager where did=id ;<br /> QUERY
PLAN <br
/>---------------------------------------------------------------------------<br/> Nested Loop (cost=0.00..269.09
rows=45width=72)<br /> -> seq scan on manager (cost=0.00..6.50 rows=45 width=36)<br /> -> Index Scan using
id1on dept (cost=0.00..5.82 rows=1 width=36)<br /> Index Cond: ("outer".did = dept.id)<br /><br />Say seq scan
retrievesdid in the order 30,10, 20.. My doubt is in what order <br />will index_getmulti return tids. How does the
scandescwork ? <br /><br />Will it return the tids as firstly macthing inners for dept=30, then dept=10 ?<br /><br
/>Pleasehelp me with this.<br /><br />Thanks and regards,<br />Suresh<br /><br /><br /><br /><br /><br /><br /><br
