The following SQL is a good example of scalar sub query tuning.
The original query takes few hours to run. Please see the query and the plan below.
SELECT SUM (FEE_PAID), MAX (INVOICE_DATE)
FROM
(SELECT STH.DATE_OF_TRAN AS INVOICE_DATE,STH.PENDING_SEQ_NO AS PENDING_TRAN_NUMBER,
(SELECT FEE_AMT
FROM FEE_TAB FT1
WHERE T_SEQ_NO =
(SELECT MAX (T_SEQ_NO)
FROM FEE_TAB FT2
WHERE P_SEQ_NO = STH.P_SEQ_NO
AND TYPE = 'AC')) AS FEE_PAID
FROM TRAN_TAB STH
)

What is this statement doing?
For each row in TRAN_TAB table, using the P_SEQ_NO, find the latest T_SEQ_NO where TYPE = ‘AC’.
Then for the that T_SEQ_NO, find the FEE_AMT and return it ( T_SEQ_NO is unique)
Finally sum up all FEE_AMTs. Also find the latest INVOICE_DATE.
Why is it taking long?
The query that should ideally take only few seconds is taking few hours.
Parallel query is enabled and both tables are with Parallel Degree 3 Instance 2. Parallel plan generated seems to be not optimal.
It is not clear why execution plan doesn’t start with TRAN_TAB table. It may be a bug or a weakness in the optimizer.
What can be done?
Often, a fast way to fix these kind of issues is to write the SQL in a different way(SQL rewrite.) Here we can think of at least four genuine options.
1. Parallel plans are known to maximize UPU usage. So we could disable parallel with a hint and see if we get a plan that is better.
2. The scalar query has an inner query too. The P_SEQ_NO = STH.P_SEQ_NO filter is only in the inner query. While this is perfectly normal, we could add the P_SEQ_NO = STH.P_SEQ_NO filter to the outer query too. This will not change the result set because T_SEQ_NO selected from the inner query has to have the same P_SEQ_NO. A legitimate rewrite. Please also note that P_SEQ_NO is indexed.
3. We can use analytical function to avoid the inner query. Hopefully that will appear less ‘complicated’ to the optimizer.
4. We can convert the scalar subquery to a join. This is also an easy change here. But for complex statement, this can get a bit difficult.
Basic Analysis
1)TRAN_TAB is a 442595 row, unpartitioned table with Parallel Degree 3 instance 2
Indexes:
TRAN_TAB_IDX1 on (P_SEQ_NO)
TRAN_TAB_IDX2 on (TRAN_SEQ_NO)
TRAN_TAB_IDX3 on (DATE_OF_TRAN)
Number of distinct values of P_SEQ_NO=36580
2)FEE_TAB is a 11,396,005 row, unpartitioned table with Parallel Degree 3 instance 2
Indexes:
FEE_TAB_IDX1 on (DATE_OF_TRAN )
FEE_TAB_IDX2 on (P_SEQ_NO )
FEE_TAB_IDX3 on (FEE_TYPE_PD)
FEE_TAB_IDX4 on (T_SEQ_NO)
Number of distinct values of P_SEQ_NO = 1 082,083
Number of distinct values of FEE_TYPE_PD = 23
Number of distinct values of T_SEQ_NO=11,396,005 (Unique)
Nearly half a million rows in the table and we need to do the look up for all of them. But the interesting thing to note here is that there are only 36580 distinct P_SEQ_NOs

Conclusion
Rewrites using analytical function or adding P_SEQ_NO = STH.P_SEQ_NO to the outer query in the scalar sub query seems to do the trick.
The amount of rewrites in this case is very minimal. All four rewrites give good improvement compared to the original query. But the join approach has significantly less LIO.
I personally think the issue with the original query may be a combination of the following exposing a weakness of the optimizer:
1) parallel, and
2) the fact that the correlation to the scalar sub query is a level deep
Note : 12c seems to have some mechanism to unnest scalar sub queries. But I did not get a chance to explore that yet.

Masteron is a banned substance by WADA and all
other anti-doping authorities worldwide. Just like hair
loss, acne growth on Masteron is individually dependent.
This may be on the again, shoulders, chest, scalp, face, stomach, arms – virtually anyplace in extreme cases.
Cystic zits (pus-filled inflammatory acne) leading to scars isn’t unheard of amongst
Masteron users, who’re predisposed to this type of
response from DHT steroids. A visit to a dermatologist and taking prescription drugs
to regulate zits is something more than a few Masteron users resort to.
HCG could cause unwanted aspect effects like gyno, so it should be taken with an aromatase inhibitor to stop this.
This stack could have zero water retention, and Anavar will increase your fat
loss capabilities.
Due To This Fact, customers should plan their cycle accordingly so as
to maximize their potential outcomes. These utilizing this model of Tren can count on to feel its effects
start inside every week, though full effects will take a period of time to manifest and be correctly loved over a longer period.
As an added bonus, this legal steroid various accommodates no synthetic hormones or poisonous chemicals,
so it’s utterly secure to be used with no danger of great opposed reactions or authorized implications.
It is important for individuals who’re thinking about using Trenbolone to
weigh the potential consequences carefully before deciding to use this steroid.
This puts Trenbolone Acetate in the identical class as Deca Durabolin (Nandrolone Decanoate).
In reality, the Trenbolone hormone itself is solely a modified form of the Nandrolone hormone.
The Trenbolone hormone carries a double bond at carbons 9
and 11, which in flip slows its metabolism, tremendously will increase its binding
affinity to the androgen receptor, and inhibits it from
aromatizing. The ensuing change makes Trenbolone one of the potent
anabolic steroids of all time. Merely by taking a look at its
structural ratings, we can begin to see how powerful
it is.
Non-drug-tested powerlifters will nearly definitely cycle trenbolone
prior to a contest. Getting enough sleep, minimizing
stress, and customarily dwelling a healthy life-style will also
assist a user’s outcomes on trenbolone. Genetics, diet, life-style, exercises, and cycle protocol will all
affect a person’s trenbolone results. Due to the androgenicity of Trenbolone,
some will try 5-alpha reductase inhibitors like Finasteride to realize safety.
Nevertheless, the 5-alpha reductase enzyme does not metabolize the
Trenbolone hormone and related inhibitors may have little or no if any
effect.
Tren is without question one of the versatile anabolic steroids as it can be used for almost any function of performance enhancement.
It’s commonly said that Testosterone is probably
the most versatile anabolic steroid and that’s a tough point to argue against,
but in relation to the numerous efficiency primarily based advantages Tren is undoubtedly
king. Fats loss and gaining of some lean mass shall be ramped up on this cycle with out water retention caused by any of the compounds.
Testosterone can be included to provide a functional degree of the hormone.
Parabolan can be used at up to 300mg weekly, and Winstrol oral at 50mg
day by day most.
However, its potency also comes with significant dangers that must be fastidiously thought of.
For athletes looking for efficiency enhancement, Trenbolone
can provide fast outcomes, but it requires a disciplined approach, together with protected
dosing, post-cycle therapy, and common health monitoring.
One Other widespread steroidal trait held
by Trenbolone Acetate is its capability to inhibit glucocorticoid
hormones.
It is a natural derivative of testosterone and is used as a performance-enhancing drug in bodybuilding, athletics, and different sports activities.
Trenbolone acetate has been used in some of
the most extreme situations possible, together with as a part of
human Biathlon doping scandals. Utilizing Trenbolone can be a safe and

steroid while minimizing the dangers to your well being.
Protein synthesis is how the physique repairs and builds
muscle tissue, whereas nitrogen retention helps to create an anabolic setting
within the muscular tissues. An anabolic state is essential for muscle hypertrophy, which is the rise in muscle size.
By stacking these two compounds, users usually experience important muscle development in a shorter
timeframe than with testosterone alone. Trenbolone Acetate is a synthetic steroid used by bodybuilders and athletes
to increase muscle mass. It is probably one of the hottest anabolic steroids available
on the market, and for good cause. Trenbolone Acetate is a powerful steroid that may allow you to obtain your targets quicker than some other anabolic steroid.
In my experience, proper dosing and administration of Trenbolone Acetate can result in vital gains in muscle mass and energy.
However, it is necessary to all the time seek the guidance of with a healthcare skilled
before starting any steroid cycle and to observe their guidance intently.
For the performance-enhancing athlete you can see there is no anabolic steroid as versatile or as helpful
as trenbolone acetate. This steroid can be used
for any cycle as it could possibly promote mass energy, muscle definition, and hardness and whole body transformation better than any steroid on earth.
In each classes this type of trenbolone has the acetate ester
added to it. Regardless of the aim of use, your genetics or rumors you could have heard,
the unwanted aspect effects of Trenbolone Acetate will all the
time include pure testosterone suppression.
Bodybuilders use it to reduce the number of injections they should have.
Nevertheless, it must be used with warning as
it could possibly trigger some undesirable unwanted facet effects corresponding
to aggression and elevated blood stress. It is important to seek the
advice of your physician earlier than using trenbolone for
slicing functions. Trenbolone Acetate, characterized by its fast-acting nature, has a shorter ester chain (acetate ester) in comparison with Trenbolone Enanthate.
To help you make an informed choice, the next table provides a comparability of Trenbolone dosage options, highlighting the beneficial dosages for varied Trenbolone variants.
Please notice that these dosages are basic guidelines and will differ depending on individual elements.
Seek The Assistance Of with a healthcare skilled or an skilled
fitness skilled to find out the most suitable dosage for your
particular wants. Deca-Durabolin (or Deca) is probably considered one of the most
popular bulking steroids we see people utilizing.
Solely barely extra Anabolic than Testosterone,
we will still see a massive amount of muscle gains when mixed with Testosterone.
The value of the raw powder to manufacture is rather more than that
of testosterone or deca. It’s in all probability the most
well-liked steroid today as a result of it’s really the most bang for your
buck. Parabolan is incessantly stacked with
many alternative steroids, depending on whether you are
bulking or chopping. Some examples embrace Anadrol, Dianabol, Deca-Durabolin, Equipoise, and Winstrol.
Usually called “Tren rage,” it is believed that individuals who
have already got an aggressive nature before
utilizing Tren are more likely to turn out to be worse while on it.
The major cause for so-called Tren-rage is the impact the androgenic compounds have on mind
chemistry, inflicting irritability and a brief fuse in some
guys.

By doing so, they can optimize their body’s fat-burning capabilities while sustaining lean muscle mass.
This method permits the lifter to expertise
the best of each worlds but must be practiced with warning and consideration to acceptable dosing and cycle
lengths to make sure a positive outcome. Winstrol

a preferable selection for newbies.

Again, that is an illegal compound that may have quite a quantity of unwanted side
effects. To scale back the risk of virilization even additional, ladies might opt to
begin taking Anavar at 5mg and enhance their dose progressively.
However, if girls take excessive doses for long periods
of time, virilization unwanted effects with Anavar alone are still
potential. However, Anavar is the exception to this rule, displaying powerful strength-building
attributes; despite not causing significant weight gain. Anavar just isn’t classed as a bulking steroid because of this, as its
muscle-building effects are inferior to different classic bulking steroids.
In terms of strength features, Anavar is considered mild whereas Winstrol is more potent.
When it comes to bodybuilding and athletic performance, anabolic
steroids are often used to enhance bodily efficiency and promote muscle
growth. Two well-liked steroids which may be incessantly
compared and debated amongst athletes and health fanatics are Anavar and
Winstrol.
There is a danger when purchasing any anabolic steroid on the black market; however, it could possibly be argued that Anavar
is especially precarious due to its high market value.
Consequently, a common rip-off we now have seen is for sellers
to dilute or substitute oxandrolone for methandrostenolone (Dianabol), which could be manufactured at
a fraction of the price. In distinction to Anavar, much less analysis has been conducted
on Winstrol with regard to the liver.
Whereas liver toxicity is a significant concern with Winstrol, a fair larger
area of concern can be related to your cardiovascular
well being. Extra particularly, what Winstrol can probably do to your cholesterol levels is not to be ignored.

In general, DHT derivatives are dry strength builders with dependable and
predictable ranges of anabolic exercise. Nitrogen retention was roughly the
same between the entire steroids evaluated within the research above [R].
DHT derivatives are sometimes perceived to be poor decisions for a mass building phase/offseason because they don’t seem to
supply as much hypertrophy because the Testosterone and
19-Nor households. If a steroid did not exhibit a extra
favorable anabolic/androgenic ratio than Testosterone, it would have been abandoned for any
software apart from pure androgen replacement in males (e.g.
Proviron).
These results are typical of Anavar’s results; however, if
customers eat in a calorie surplus, fat loss is prone to be less than these illustrated above.
Thus, food regimen remains an essential factor in figuring out body
composition on Anavar. Deciding between Anavar and Winstrol depends on your

responsibly to remain healthy in the long run. By planning well, sticking to the proper doses, and checking

as lean and shredded as possible. While Clenbuterol suppresses the appetite, Anavar can improve starvation in some customers.

with an Anavar-only cycle at the really helpful 10mg daily dose.
Most cycles will utilize testosterone past the 8-week Anavar
cycle size, extending to 12 weeks with testosterone before beginning
post-cycle remedy. You can count on wonderful results without
water retention with this cycle.
Anavar has a minimal effect on cholesterol levels,
and it may even enhance HDL (good) levels of cholesterol.
Winstrol, on the other hand, can decrease
HDL cholesterol and improve LDL (bad) cholesterol levels.
Winstrol is a slicing steroid that’s used to assist burn fat and
enhance muscle definition and hardness. Winstrol is generally thought of to be more potent than Anavar by way
of its anabolic and androgenic effects. This is as a outcome of
Winstrol is a derivative of dihydrotestosterone (DHT), which is a
more potent androgen than testosterone, the hormone from which Anavar is derived.
We’re speaking about two compounds, designed over half a century ago,
that both – surprise-surprise – have been NOT supposed for bodybuilding.
For instance, I scale back the daily dose by half every two weeks until I’m again right
down to the beginning dosages of 20mg of Anavar and 25mg of Winstrol per day.
This helps my physique readjust and prevents potential
side effects from the abrupt cessation of the steroids.
However, if you’re contemplating using Anavar, you might be questioning if it’ll show up in a blood check.
