How to achieve this logic?
I have 3 tables with structure as below.
create table T1
(ColA VARCHAR2 (50 CHAR) NOT NULL,)
ColB VARCHAR2 (50 CHAR) NOT NULL,
Teachers VARCHAR2 (50 CHAR) NOT NULL,
date of startdt
float (126) of t1_price 0 not null by default)
create table T2
(ColA VARCHAR2 (50 CHAR) NOT NULL,)
ColB VARCHAR2 (50 CHAR) NOT NULL,
Teachers VARCHAR2 (50 CHAR) NOT NULL,
date of startdt
float (126) of t2_price 0 not null by default)
create table T3
(ColA VARCHAR2 (50 CHAR) NOT NULL,)
ColB VARCHAR2 (50 CHAR) NOT NULL,
Teachers VARCHAR2 (50 CHAR) NOT NULL,
date of startdt
float (126) of t3_price 0 not null by default)
Requirement is to fill the T3_price in the table T3 provided that if there is an entry in T1 for same startdate, T1_price should be used elsewhere last entry of T2 must be used. Some examples of data.
Registrations in Q1
ColA | ColB | Teachers | Startdt | T1_Price |
VAL1 | VAL2 | VAL3 | 14/09/2014 | 100 |
VAL1 | VAL2 | VAL3 | 21/09/2014 |
100
VAL1
VAL2
VAL3
10/12/2014

Registrations in Q2
ColA | ColB | Teachers | Startdt | T2_Price |
VAL1 | VAL2 | VAL3 | 09/07/2014 | 200 |
VAL1 | VAL2 | VAL3 | 10/05/2014 | 300 |
09/07/2014 |
14/09/2014
21/09/2014
28/09/2014
10/05/2014
10/12/14
19/10/14
T1_Price
100
100
200
T2_Price
200
200
300
T3_Price should be
200
100
100
200
300
200
300
Can you get it someone please let me know if the above requirement can be achieved in a single update statement? I tried with the statement below.
UPDATE r T3
SET T3_price =
(NVL)
(SELECT T1_Price
T1 d
WHERE r.colA = d.ColA
AND r.ColB = d.ColB
AND r.ColC = d.ColC
AND r.startdt = d.startdt),
(SELECT T2_Price
B T2
WHERE r.colA = b.ColA
AND r.ColB = b.ColB
AND r.ColC = b.ColC
AND r.startdt > = b.startdt))) < < < < I don't know that I'm missing my logic in that statement.
WHERE THERE ARE
(SELECT T1_Price
T1 d
WHERE r.colA = d.ColA
AND r.ColB = d.ColB
AND r.ColC = d.ColC
AND r.startdt = d.startdt
UNION
SELECT T2_Price
B T2
WHERE r.colA = b.ColA
AND r.ColB = b.ColB
AND r.ColC = b.ColC
AND r.startdt > = b.startdt);
Hello
That's what you asked for:
MERGE INTO dst of t3
WITH THE HELP OF)
SELECT t3.cola, t3.colb, t3.colc, t3.startdt
MAX (t1.t1_price) AS t1_price
MAX (t2.t2_price) DUNGEON (DENSE_RANK LAST ORDER BY t2.startdt)
AS last_t2_price
T3
LEFT OUTER JOIN t1 ON t1.cola = t3.cola
AND t1.colb = t3.colb
AND t1.colc = t3.colc
AND t1.startdt = t3.startdt
LEFT OUTER JOIN t2 ON t2.cola = t3.cola
AND t2.colb = t3.colb
AND t2.colc = t3.colc
AND t2.startdt<=>=>
GROUP OF t3.cola, t3.colb, t3.colc, t3.startdt
) CBC
WE (dst.cola = src.cola
AND dst.colb = src.colb
AND dst.colc = src.colc
AND dst.startdt = src.startdt
)
WHEN MATCHED THEN UPDATE
SET dst.t3_price = NVL (src.t1_price, src.last_t2_price)
;
Here's what Q3 looks after execution of this MERGER:
COLA, COLB TEACHERS STARTDT T3_PRICE

Thank you in advance!
Use a solid layer of the color of your choice then add a mask and change his pen:
The effects coming from the photograph is called vignetting or vignnete
Another way is to add a bright spot and animated, but its more difficult, I hope it works

How to achieve this effect?
I'm looking to recreate the effect as seen in the video below at 01:10.
https://www.YouTube.com/watch?v=kThmu-o_nhI
Any help would be appreciated, especially the part where each individual smile falls differently. Also, when every smile appears, I thought at first it was just a scale in, but looks like it has a different effect to him.
Thank you!
I had manually on this sucker. nothing to it. Take a look:
you create two layers in photoshop or illustrator
import into Ae. make an animation to one of them - the 'different' effect you notice - this is called an overflow-under-overtaking animation and you must use the graph for this editor. First, you set your scale to 0 and after 10 images to 100 like this:
then you go into the graphics editor and on the value graph, you change your curve of this:
to do this:
See that it is a go-around and extensions of waveform more about it here:
http://www.Motionscript.com/articles/bounce-and-overshoot.html
This is my clumsy way to explain how it works
Move keyframes until you get the distribution right and now you've got it
so we got the scale just as it should be! now as for the position - since we know that we want more of them, we should try to work D.R.Y - do not repeat yourself - make us an animation and duplicate instead of deal with alone. We will add location to the mix and we'll take smiley all the way upward and downwards, then some so we have room when we scale it afterwards.
now, we want to change the speed a bit, so we'll go into the graphics editor on the speed graph and adjust it like this:
This is the graph of speed so at the beginning, we want less speed and gradually increase
now, we got a dandy end of an animation
now us precomp this layer and call him smiley-animation and press the button cut so we can now version 13.8 appreciate the beautiful cropped a pre comped layer limits
we drag the anchor in the Middle, so it will be easier to position the layers a scale them subsequently
now reproduce us like crazy by pressing Ctrl + D and drag it into the window of the model with the selection rectangle and what not
and now reduce us some of the layers a little
and offset the layers
now, we've got this amazing thing:
Oops... you have one coming down enough. not to worry - it's all in the same model! We can go inside and drag it down!
What is in laughing face? We work D.R.Y. we are simply duplicate the animation precomp smiley in the project window and name it funny animation
go inside and replace the layer with layer laughing smiley
and now in our main composition we replace some of the smiley with precomps precomps laughing in the project window
now, we are DONE: TAKE a BREAK!
