SELECT * FROM ___ WHERE C1=:a AND C2=:b AND C3=:c AND C4=:d AND C5=:e;
There is a primary key index on C1, C2, C3.
The explain plan does show an index unique scan using the primary key
index.
The V$SQLAREA stats for this statement are:
EXECUTIONS =
1,471,320
ROWS_PROCESSED = 37,291,384
How is it possible to use a unique index scan and return more than 1
row
per execution? Or is there a problem with the stats?
It is broken in 8.0.5 on down...
