Hi all,
I got this query, I'm having indexes for PropertyId and Dates columns across all the tables, but still it takes ages to get me the result. What indexes would be proposed on this, or I'm helpless?
FROM STG_Property a
FULL OUTER JOIN
STG_PropConfirmedLogs b
ON (a.PropertyId = b.PropertyId AND a.p_LastModified = b.p_Modified_Date)
FULL OUTER JOIN
STG_PropConnectionFeesLogs c
ON ((a.PropertyId = c.PropertyId AND a.p_LastModified = c.p_ChangedOn)
OR (b.PropertyId = c.PropertyId AND b.p_Modified_Date = c.p_ChangedOn))
FULL OUTER JOIN
STG_PropDeletedLogs d
ON ((a.PropertyId = d.PropertyId AND a.p_LastModified = d.p_DeletedOn)
OR (b.PropertyId = d.PropertyId AND b.p_Modified_Date = d.p_DeletedOn)
OR ( c.PropertyId = d.PropertyId AND c.p_ChangedOn = d.p_DeletedOn))
FULL OUTER JOIN
STG_PropFEWALogs e
ON ((a.PropertyId = e.PropertyId AND a.p_LastModified = e.p_Modified_Date)
OR (b.PropertyId = e.PropertyId AND b.p_Modified_Date = e.p_Modified_Date) OR (c.PropertyId = e.PropertyId AND c.p_ChangedOn = e.p_Modified_Date)
OR (d.PropertyId = e.PropertyId AND d.p_DeletedOn = e.p_Modified_Date))
FULL OUTER JOIN
STG_PropInSewerNetworkLogs f
ON ((a.PropertyId = f.PropertyId AND a.p_LastModified = f.p_Modified_Date)
OR (b.PropertyId = f.PropertyId AND b.p_Modified_Date = f.p_Modified_Date)
OR (c.PropertyId = f.PropertyId AND c.p_ChangedOn = f.p_Modified_Date)
OR (d.PropertyId = f.PropertyId AND d.p_DeletedOn = f.p_Modified_Date)
OR (e.PropertyId = f.PropertyId AND e.p_Modified_Date = f.p_Modified_Date)) FULL OUTER JOIN
STG_PropTypeLogs g
ON ((a.PropertyId = g .PropertyId AND a.p_LastModified = g.p_LastModified)
OR (b.PropertyId = g.PropertyId AND b.p_Modified_Date = g.p_LastModified)
OR (c.PropertyId = g.PropertyId AND c.p_ChangedOn = g.p_LastModified)
OR (d.PropertyId = g.PropertyId AND d.p_DeletedOn = g.p_LastModified)
OR (e.PropertyId = g.PropertyId AND e.p_Modified_Date = g.p_LastModified)
OR (f.PropertyId = g.PropertyId AND f.p_Modified_Date = g.p_LastModified))
