Why is this game of case statements do not parallel execution?
I have the following Subvi:
I had a similar version which had specific cases for specific devices, but I wanted to make it more generic. I tested their work in parallel before the Subvi to GET all THE DATA is re-entrant I wonder if the merge errors feature prevents cases work properly. Maybe having the error returned to the Subvi on the top of the terminal will make a difference? Just try to understand what is happening.

James,
Why the constant true connected to the conditional tunnel?
I was simulating a Subvi, which has a Boolean result. He did not share his code so I don't have the Subvi himself.
I see now why OP does without a loop For, if there are more devices there carrots. The loop For could save code duplication to a minimum the number of cores.

Hello
I'm having a strange problem with a case statement. I'm passing is a Boolean value that is set to false, but the case statement never switches to the loop of "false". I have attached a word doc who did the screen has a step of this unique through being shot. The photo of the top has the case highlighted with the probe #8 beside him indicate 'False. ' In the lower screen shot is the very next step that highlights the outside circle while ' loop', but the case statement is always 'True '. Anyone seen this before?

Hey Mello,
Well, I see what you're saying and you are right, the problem is the case statement works when highlight of execution. But I have a main case statement in the loop that either allows the state machine to execute a loop or hides them and that case is triggered for no steps to true or false. So that was the reason why I sent the first e-mail because I could see this case change, but not the smallest. But if this is the fix well I'll run with it and lets see case statement switch the highlight of the performance.
Thanks again.

CASE STATEMENT DOES NOT HIERARCHY
Hi Experts
I have this case statement:
BOX WHEN ' @{pvCalType} "="Cal1"THEN"Calendar Cal1"". "" Year. "
WHEN ' @{pvCalType} "="Cal2"THEN"Calendar Cal2"". "" Year
ANOTHER NULL
END
All the columns in the YEAR of different sizes have properties of the hierarchy.
When I view my results of this statement, there is no hierarchy.
I want the hierarchy in order to drill down of the YEAR > QUARTER > MONTHS
Help, please.
Hello
do you have other possible values for "pvCalType"?
If not try this formula: "@{pvCalType} schedule". " Year. "
(not sure this is the right syntax, if it does not work after the return of the error and I get the right thing...)

Chanchal wankhade.I think you meant:
CASE
WHEN SUPERIOR (V_TEST) LIKE "% UU" THEN V_TEST: = REPLACE (UPPER (V_TEST), 'UU', 'U');
WHEN SUPERIOR (V_TEST) LIKE '% OO %' THEN V_TEST: = REPLACE (UPPER (V_TEST), 'OO', 'O');
...
'%' is a wildcard character only on the right-hand side of the LIKE operator. '%' has no particular meaning when you use the = operator.
You can also use a CASE expression, rather than a CASE statement to this:
v_test: = UPPER (p_test);
v_test: = BOX
WHEN v_test LIKE "% UU" THEN REPLACE (v_test, 'UU', 'U')
WHEN v_test LIKE "% UU" THEN REPLACE (v_test, 'OO', 'o')
...
END;
Whatever it is, if v_test contains different models (for example "HOOVER VACUUM"), only 1 of them will be changed. Is that what you want?
If this isn't the case, after a few examples of data (CREATE TABLE and INSERT statements) and the results desired from these sample data. Explain how you get these results from these data.

Why this CASE statement would not work?
If I use a CASE in my SELECT statement and met a strange thing and just need help to understand why he did it.
When I type this, it does not work:
CASE TRIM (Column1)
WHEN NULL THEN Column2
WHEN 'foo' THEN Column2
Of ANOTHER Column1
END AS NewColName
I use this query in an Oracle procedure to insert data into another table. The data inserted in the column of NewColName end up being 4 empty spaces, located in Column1. In the logic of this, TRIM must remove all the empty spaces, and he should get mapped to the first statement WHEN, who must insert the value of Column2, but that does not occur. I tried the following versions of the first line as well:
LTRIM (RTRIM (Column1)) CASE
CASE of REPLACE (Column1, ' ', ")
and they all produce the same result. I also tried to change WHEN NULL for WHEN " and it changed nothing. However, when I rewrite the statement in this way it works the way it should:
CASE
WHEN TRIM (Column1) IS NULL, Column2
WHEN TRIM (Column1) = 'foo' THEN Column2
Of ANOTHER Column1
END AS NewColName
In my mind, it seems that these two methods are trying the same thing, why we could work and the other not? Only, it has no sense to me.
Thank youHello
Welcome to the forum.
In your first statement, you have
WHEN NULL THEN.
This is the same as x = NULL.
Nothing is never equal to NULL, if you find yourself in your ELSE clause.

Table: digital_val

query:
Select case when c1 = "san1" then c2,.

I'm more curious why, when you select 2 rows, you expect a result of row?
WITH digital_val
AS (SELECT 1 AS 'Sno', 'San1"C1, c2 FROM DUAL 11)
UNION ALL
2 SELECT AS 'Sno', 'San2"C1, c2 FROM DUAL 22)
SELECT CASE WHEN c1 is "San1" THEN END AS A c2.
CASE WHEN c1 = "San2" THEN END AS B c2
OF digital_val;
With no other input, if you select 2 rows, you get 2 rows. One of the other solutions use a max function, but is this really what you want, does not specify?

I'm editing in the bright room of Adobe and when I change in the develop module, I get the image I want, but when I see in the library module in its final State, it changed and degraded. Why is this happening?
The difference between the raw edition photo and editing a PSD is that the PSD has black points and white pinned to the visible pixel values, the raw photo has still "headroom" with values of pixel darker than black visible and brighter than white, so when you export the raw file , there may be details that have improved (or obscured if it was another type of image) of the perception and mapping of the Compensation of the black spot on the final color profile.
This means not PS is better or LR is lower, it is enough for you to go to a different type of image. If you don't have PS to do final Assembly, you can probably do the same thing by exporting the raw in a 16 bit ProPhotoRGB TIF file, re-import this TIF and then set it LR, possibly using the tone curve to make the pitch black dark areas.

Why is this code not work and it is possible to use a case statement in a Page Apex process
Of course, it is possible to use a CASE statement or expression (it is the latter) in a page APEX process. However, it is not possible to use an invalid syntax while doing so. Part of a clause INSERT INTO can contain only static column names.
In general the SQL expressions (and also the bind variable, another cause frequent errors of syntax) can be used only in
- the projections of the SELECT queries and subqueries
- the right side of the disposals in the SET update clause
- the lists of VALUES of INSERTs
- WHERE clause predicates

It's a good idea, but it can be simplified, eliminating unnecessary subqueries:

Case statement in where clause
Hello
I have to write the following query using the value of the l_var variable in the case statement
How do I get there?
Select col3of the test
where col1 = "A".
and the case
When l_var = "Y' and col2 = 'B '.
When l_var = 'n' and col2 = 'C '.
end;
In your expression
case
When l_var = 'Y' and col2 = 'B '.
When l_var = ' only then col2 <> 'B '.
end;
you try to return a Boolean (True or False) value like 'then' value of the CASE statement.
Values Boolean are not an Oracle SQL data type, you cannot use the true/false result of col2 = 'B' as an expression. This is why it does not work.
It's even more simple as:
Select col3
of the test
where col1 = "A".
and ((l_var = «Y» et col2 = «B») or (l_var = ' no and col2 <> 'B'))
If you really want a CASE statement then:
Select col3
of the test
where col1 = "A".
and the CASE WHEN l_var = 'Y', THEN CASE WHEN col2 = 'B', 1 ELSE 0 END
WHEN l_var = ' no CASE THEN WHEN col2 <> 'B', 1 ELSE 0 END
END = 1

[8i] Case statement generates ORA-00932: inconsistent data types
Note: I work with a 8i database (Yes, he's old enough) and in this case, I have to deal with the types of data (e.g. TANK), I gives me to work with.
I am trying to calculate the amount of time product expected between manufacturing steps. As I found out though, sometimes I get a negative value then subtract the date the previous step ends the date of that ongoing stage begins. Since it is generally impossible to start a later stage before a previous step (imagine trying to screw a cap on a bottle that has no son Cup yet - it just may not happen), what I found is that sometimes two steps are started the same day and finished the same day (although not necessarily the day they started). This situation CAN occur when a person is two steps and connected to two steps at the same time, rather than log on to one, then the other. So what I need to do in these situations, is to replace the negative number by zero (I'll treat the stage as having no time-out).
Some examples of data:
(Note: the data set real is the result of a query and has about 200 K lines and columns more, but this should be representative enough to find a solution that works on my real application.)
Here's the query I use that sometimes returns negative values:CREATE TABLE steps ( item_id CHAR(25) , ord_nbr CHAR(10) , sub_nbr CHAR(3) , step_nbr CHAR(4) , start_date DATE , finish_date DATE ); INSERT INTO steps VALUES ('A','0000000001','001','0010',TO_DATE('01/01/2011','mm/dd/yyyy'),TO_DATE('01/02/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('A','0000000001','001','0020',TO_DATE('01/01/2011','mm/dd/yyyy'),TO_DATE('01/02/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('A','0000000001','001','0030',TO_DATE('01/05/2011','mm/dd/yyyy'),TO_DATE('01/06/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('A','0000000001','002','0010',TO_DATE('01/01/2011','mm/dd/yyyy'),TO_DATE('01/02/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('A','0000000001','002','0020',TO_DATE('01/04/2011','mm/dd/yyyy'),TO_DATE('01/04/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('A','0000000001','002','0030',TO_DATE('01/06/2011','mm/dd/yyyy'),TO_DATE('01/07/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('B','0000000002','001','0005',TO_DATE('01/10/2011','mm/dd/yyyy'),TO_DATE('01/12/2011','mm/dd/yyyy')); INSERT INTO steps VALUES ('B','0000000002','001','0025',TO_DATE('01/10/2011','mm/dd/yyyy'),TO_DATE('01/12/2011','mm/dd/yyyy'));
These are the results I want to see:SELECT item_id , ord_nbr , sub_nbr , step_nbr , start_date - last_step_finished FROM ( SELECT s.* , LAG (s.finish_date) OVER ( PARTITION BY s.item_id , s.ord_nbr , s.sub_nbr ORDER BY s.step_nbr ) AS last_step_finished FROM steps s ); Returns: ITEM_ID ORD_NBR SUB STEP START_DATE-LAST_STEP_FINISHED ------------------------- ---------- --- ---- ----------------------------- A 0000000001 001 0010 A 0000000001 001 0020 -1.000 A 0000000001 001 0030 3.000 A 0000000001 002 0010 A 0000000001 002 0020 2.000 A 0000000001 002 0030 2.000 B 0000000002 001 0005 B 0000000002 001 0025 -2.000
And that's what I tried to do to get these results (comment pointed out which line has generated the error):ITEM_ID ORD_NBR SUB STEP START_DATE-LAST_STEP_FINISHED ------------------------- ---------- --- ---- ----------------------------- A 0000000001 001 0010 A 0000000001 001 0020 0.000 A 0000000001 001 0030 3.000 A 0000000001 002 0010 A 0000000001 002 0020 2.000 A 0000000001 002 0030 2.000 B 0000000002 001 0005 B 0000000002 001 0025 0.000
I know that I had errors in data type incompatible before with case statements in this particular 8i database, but I can't seem to understand why I'm getting one this time. I think it has something to do with the NULL value which may occur for last_step_finished. Also, if I change the case statement to:SELECT item_id , ord_nbr , sub_nbr , step_nbr , CASE WHEN start_dt - last_step_finished < 0 THEN 0 ELSE start_dt - last_step_finished -- THIS LINE GENERATES THE ORA-00932 ERROR END AS days_in_queue FROM ( SELECT s.* , LAG (s.finish_date) OVER ( PARTITION BY s.item_id , s.ord_nbr , s.sub_nbr ORDER BY s.step_nbr ) AS last_step_finished FROM steps s );
the query works fine. But, I'm not NULL, I 0. In the level of this request, I'll take the averages by item_id/step_nbr, and I want that 0 s to be included in the average. (NULL values, as far as I know, would be excluded. AVG(null,_1,_2) = AVG (1,2) = 1.5 NOT AVG (0,1,2) = 1)., CASE WHEN start_dt - last_step_finished < 0 THEN NULL ELSE start_dt - last_step_finished -- THIS LINE GENERATES THE ORA-00932 ERROR END
Thanks in advance!CASE requires that all expressions to be of the same type. Numeric data type code is 2, then that date produced different internal datatype 14:
