/**
@class select_unit_ext
The class used when processing rows produced by operands of query expressions
containing INTERSECT ALL and/or EXCEPT all operations. One or two extra fields
of the temporary to store the rows of the partial and final result can be employed.
Both of them contain counters. The second additional field is used only when
the processed query expression contains INTERSECT ALL.
Consider how these extra fields are used.
Let
table t1 (f char(8))
table t2 (f char(8))
table t3 (f char(8))
contain the following sets:
("b"),("a"),("d"),("c"),("b"),("a"),("c"),("a")
("c"),("b"),("c"),("c"),("a"),("b"),("g")
("c"),("a"),("b"),("d"),("b"),("e")
- Let's demonstrate how the the set operation INTERSECT ALL is proceesed
for the query
SELECT f FROM t1 INTERSECT ALL SELECT f FROM t2
When send_data() is called for the rows of the first operand we put
the processed record into the temporary table if there was no such record
setting dup_cnt field to 1 and add_cnt field to 0 and increment the
counter in the dup_cnt field by one otherwise. We get
|add_cnt|dup_cnt| f |
|0 |2 |b |
|0 |3 |a |
|0 |1 |d |
|0 |2 |c |
The call of send_eof() for the first operand swaps the values stored in
dup_cnt and add_cnt. After this, we'll see the following rows in the
temporary table
|add_cnt|dup_cnt| f |
|2 |0 |b |
|3 |0 |a |
|1 |0 |d |
|2 |0 |c |
When send_data() is called for the rows of the second operand we increment
the counter in dup_cnt if the processed row is found in the table and do
nothing otherwise. As a result we get
|add_cnt|dup_cnt| f |
|2 |2 |b |
|3 |1 |a |
|1 |0 |d |
|2 |3 |c |
At the call of send_eof() for the second operand first we disable index.
Then for each record, the minimum of counters from dup_cnt and add_cnt m is
taken. If m == 0 then the record is deleted. Otherwise record is replaced
with m copies of it. Yet the counter in this copies are set to 1 for
dup_cnt and to 0 for add_cnt
|add_cnt|dup_cnt| f |
|0 |1 |b |
|0 |1 |b |
|0 |1 |a |
|0 |1 |c |
|0 |1 |c |
- Let's demonstrate how the the set operation EXCEPT ALL is proceesed
for the query
SELECT f FROM t1 EXCEPT ALL SELECT f FROM t3
Only one additional counter field dup_cnt is used for EXCEPT ALL.
After the first operand has been processed we have in the temporary table
|dup_cnt| f |
|2 |b |
|3 |a |
|1 |d |
|2 |c |
When send_data() is called for the rows of the second operand we decrement
the counter in dup_cnt if the processed row is found in the table and do
nothing otherwise. If the counter becomes 0 we delete the record
|dup_cnt| f |
|2 |a |
|1 |c |
Finally at the call of send_eof() for the second operand we disable index
unfold rows adding duplicates
|dup_cnt| f |
|1 |a |
|1 |a |
|1 |c |
