Case statement with several ATHENS
Try to see if the following is possible:
-Case when regexp_like (code1, ' 123') or code1 = "456"
then "Category1".
Where regexp_like (code1, ' 123')
then "Category2".
Another null
end category
Then, of course, that no record being updated with the title of Category2 as criteria code1 already was met.
I am trying to create 2 files for each instance of regexp_like (code1, ' 123'). One record with "Category1" and one with "Category2".
Thank you
I thought that too, but for this:

Case statement with a select & date in
Hello everyone,
This is my first discussion, so please bare with me.
I am trying to write a case statement with a select statement that compares the dates.
When I write an instruction box with a select statement in it compares everything but dates it works fine. Once the date is there, he collapses.
Here is a super simple example of what I'm trying to do, "b.in_serv_dt" is a date
Select unit_no,
case when ((sélectionnez b.in_serv_dt de b unit_dept_comp_main où a.unit_id = b.unit_id et b.in_serv_dt) > = 1 January 2012 "") then "everybody wins."
When ((sélectionnez b.in_serv_dt dans l'unit_dept_comp_main b où a.unit_id = b.unit_id et b.in_serv_dt) < = 1 January 2012 "") then "Nobody wins".
end
of ottawa_unitmain_v one
Any help would be greatly appreciated
Thank you very much
Hello
your statement of formatting:
Select unit_no
case when ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
and b.in_serv_dt
") > = JANUARY 1, 2012"
) and then "everybody wins."
When ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
and b.in_serv_dt
)<=>
) and then "no winner".
end
of ottawa_unitmain_v oneI see "partial conditions": <... and="" b.in_serv_dt="">> that have no meaning.
I guess it's a kind of "typo" and I ignore them.
If the statement is:
Select unit_no
case when ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
") > = JANUARY 1, 2012"
) and then "everybody wins."
When ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
)<=>
) and then "no winner".
end
of ottawa_unitmain_v oneI guess that the "b select" retrieve one line, through the design of database (forced...)
As already written: be careful with data types: avoid "implicit conversions" (when you compare different data types, Oracle has convert the data type of the other side, a side example: "mystring = mynumber" is transformed into 'TO_NUMBER (mystring) = mynumber', or 'mydate = mystring' translates mydate = TO_DATE (mystring,
) ")
Even better: use explicit conversions, use explicit formats when necessary.
Best: use no conversion on columns from the constants, but use the correct data type for the constant.With this in mind:
Select unit_no
case when ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
) > DATE = ' 2012-01-01'
) and then "everybody wins."
When ((select b.in_serv_dt
of unit_dept_comp_main b
where a.unit_id = b.unit_id
)<= date="">
) and then "no winner".
end
of ottawa_unitmain_v one
But note that b.in_serv_dt EQUAL to 1 January 2012 (at 00:00:00) is OK for both WHEN the conditions; then the a "win."Now: the subselect statement is identical in the 2 options of the case... You could work differently: (I add the "ELSE" in case one line as NULL in_serv_dt;) I guess that an INNER JOIN is OK, maybe you need a LEFT OUTER JOIN (if some lines of A have no corresponding row in B)
SELECT a.unit_no
, CASE WHEN b.in_serv_dt > = DATE '' 2012-01-01
THEN "everyone wins"
WHEN b.in_serv_dt< date="">
While "Nobody wins".
ELSE ' who knows... ". »
END who_wins
Of ottawa_unitmain_v one
INNER JOIN unit_dept_comp_main b
ON a.unit_id = b.unit_id

Hi all.
I use a case statement to represent the values for different regions in a command prompt. I'm having some difficulties, with the values in the case statement. Here is an example of a simplified and shortened my code version.
CASE
WHEN 'Region '. "" Region name "="A"THEN"AMERICA ".
WHEN 'Region '. "" Region name "= 'B' THEN 'CHINA '.
WHEN 'Region '. "" Region name "= 'C' THEN 'EUROPE '.
WHEN 'Region '. "' Name of the region ' = 'A' AND 'B' AND 'C' THEN 'GLOBAL '.
END
My error when I use it in my statement. The formula is accepted, however, all the values are displayed in my guest except 'GLOBAL '.
How can I be able to assign a "GLOBAL"value in my guest? ".
Jagadekara I think that you do not get the point. Any given row retrieved from a data source cannot have all three at one point values!
AJ was trying to tell you, is that your CASE logic has no sense at all.

A CASE statement with additional where clause
Hi all
I need assistance in which this obligation clause
Table:-balance_table
Columns:-balance_type, balance_amount, balance_month, budget_name
balance_type column had given 'Real' OR 'Budget '.
Now I am trying to extract data such as: if: entered_month is Mar-2009 then before and including Mar-2009 will show real balance sheet Date and after Mar-2009 will show budget data.
It works fine, I need to add a condition more restrict the budget name, there are several budget_name in the table for balance_type = 'Budget '.
SELECT SUM (balance_amount), balance_type, balance_month
OF balance_table
WHERE balance_type =
(CASE
WHEN balance_month < =: entered_month
THEN 'real '.
ANOTHER 'Budget '.
END
)
AND budget_name = 'BUDGET1.
Balance_type GROUP, balance_month
Stated above is erroneous because ' AND budget_name = ' BUDGET1 "clause restricts the set of data."
Please help in contrcuting where clause 1) to sort the data according to Budget/actual and 2) for specific budgets, so budget_type = Budget
Thank you
BobinThat should do it.
SELECT SUM (balance_amount), balance_type, balance_month FROM balance_table WHERE (balance_type = 'Actual' and balance_month <= :entered_month ) or (balance_type = 'Budget' and balance_month > :entered_month and budget_name = :entered_budget_name ) GROUP BY balance_type, balance_month ORDER BY 2See you soon

Closure of a state machine in queue event with several parallel loops
I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)
I look forward to any comments on my as well code, if someone is willing to offer it.
My program needs:
If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.
Architectural details:
The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.
During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".
In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".
HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.
I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.
I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.
Thank you!
First of all, close the notifier outside loops with your queues. Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

Interrupted SQL statement and start several times with several SQL_EXEC_ID
Hi all
We meet a strange phenomenon, maybe someone can help.
We see that sometimes, when our client runs a single statement, implemented Oracle to process the statement with a special SQL_EXEC_ID, but after a while stops and starts processing the statement along with different SQL_EXEC_ID. Then, after a while, it happens again - stop Oracle processes the statement and start from the beginning with the new SQL_EXEC_ID. This happens again and again until we kill all of the other sessions on the database (then it ends).
What we see exactly: Client executes the statement (sql_id = "2tp7pz6yv87qp"). Monitor us v $ SQL_MONITOR and get this:
SELECT Sql_id, sql_exec_id, to_char (SQL_EXEC_START, "HH24:MI:SS MON-DD-YYYY) SQL_EXEC_START, status OF V$ SQL_MONITOR where sql_id = '2tp7pz6yv87qp' ORDER BY SQL_EXEC_START DESC;
2tp7pz6yv87qp 16777216 28 may 2015 07:19:14 the EXECUTION
After a while check us again and see this:
2tp7pz6yv87qp 16777217 28 may 2015 07:36:17 the EXECUTION
2tp7pz6yv87qp 16777216 28 may 2015 07:19:14 FACT
After a while, we see this:

and so on — will happen again and again until we kill all of the other sessions in the database.
When comparing the follow-up of the different SQL_EXEC_IDs SQL reports, we see that each of them did exactly the same job: used the same execution plan, beginning treatment she even read/wrote the same amount of e/s and each of them stopped at the same point during execution. You can see that for each SQL_EXEC_ID execution 'stops' in the middle and never reach the end of the plan. She always stops in the JOIN by HASH and never continue to the next steps in the implementation plan.
When you look more deeply, we see in V$ ACTIVE_SESSION_HISTORY always last thing that happens for every SQL_EXEC_ID is HASH JOIN RIGHT OUTER (SQL_PLAN_OPERATION = HASH and SQL_PLAN_OPTIONS = RIGHT OUTER JOIN). Then comes the new SQL_EXEC_ID and it starts to do the same thing as the previous SQL_EXEC_ID did when it was launched.
Kill all other sessions, run finally ends. We see that the final (successful) SQL_EXEC_ID work and completes his plan to run to completion.
When executing the same single statement (when it comes to the single session in the database), it ends with a single SQL_EXEC_ID. Its SQL monitoring report looks like the final execution when the phenomenon occurs after killing all other sessions.
-We checked that the customer executing the query only once. AWR also only shows simple execution of the query.
-We have reproduced in many different clients (plus SQL, JDBC thin client OIC and DBMS_SCHEDULER job).
-It has no PARALLEL in the query or table.
-In this case for different statements (different INSERT-SELECT and MERGE instructions).
-Version: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production
Does anyone have an idea?
Finally found the root cause of the problem.
This phenomenon occurs when the cursor of the active query being invalidated. This can occur in several scenarios, in our case, what happens when we work on a single partition (read or write) and perform DDL operations on different partitions of the same or the tables.
Steps to reproduce:
1 launch long command DML that affect the single partition
2. in the course of executing this SQL, do one of the following values in a session different all 1 minute:
2.1 do the indexes to a different partition unusable: ALTER TABLE X EDIT PARTITION Y UNUSABLE LOCAL INDEX
2.2 rebuild the unusable index of different partition: ALTER TABLE X EDIT PARTITION Y REBUILD UNUSABLE LOCAL INDEX
2.3 a partition different truncate
Support of Oracle we were told that this problem is known and there are several requests for bugs and improvements thereon, for example this one:
Bug 12905327 : TRUNCATE to an INVALID PARTITION TABLE UNNECESSARILY IMMEDIATELY all THE SLIDERS
In our case (ETL process), we used to perform all these operations DDL and DML operations long (we work on different partitions in parallel). In order to solve, we have separated these operations to the different phases in our process and don't be DDL and DML operations at the same time more. This solved the problem for us.

Help with making SQL query references to column aliases in the Case statement
I need help with a sql query that I'm trying. I can go about it the wrong way, but I would be grateful if I could get any suggestions on possible solutions. This is my query:
SELECT DISTINCT spriden_pidm, spriden_id id, spriden_last_name | ',' | spriden_first_name name,
CASE
WHEN rcresar_comm_code_01 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_01
WHEN rcresar_comm_code_02 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_02
WHEN rcresar_comm_code_03 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_03
WHEN rcresar_comm_code_04 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_04
WHEN rcresar_comm_code_05 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_05
WHEN rcresar_comm_code_06 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_06
WHEN rcresar_comm_code_07 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_07
WHEN rcresar_comm_code_08 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_08
WHEN rcresar_comm_code_09 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_09
WHEN rcresar_comm_code_10 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_10
END acg_elig_comm_code
CASE
WHEN acg_elig_comm_code = ' 268' THEN 'rigorous HS course. "
WHEN acg_elig_comm_code = '269' THEN ' 2 or several AP or IB"
WHEN acg_elig_comm_code = '270' THEN 'NOC as possible ".
END comm_code_description
OF spriden, rcresar, rcrapp1
WHERE (rcresar_comm_code_01 IN ('268 ', '269', ' 270')
OR rcresar_comm_code_02 ('268 ', '269', ' 270')
OR rcresar_comm_code_03 ('268 ', '269', ' 270')
OR rcresar_comm_code_04 ('268 ', '269', ' 270')
OR rcresar_comm_code_05 ('268 ', '269', ' 270')
OR rcresar_comm_code_06 ('268 ', '269', ' 270')
OR rcresar_comm_code_07 ('268 ', '269', ' 270')
OR rcresar_comm_code_08 ('268 ', '269', ' 270')
OR rcresar_comm_code_09 ('268 ', '269', ' 270')
OR rcresar_comm_code_10 ('268 ', '269', ' 270'))
Rcresar_aidy_code = & aidy_code
AND rcrapp1_aidy_code = rcresar_aidy_code
AND rcrapp1_curr_rec_ind = 'Y '.
AND rcrapp1_seq_no = rcresar_seq_no
AND spriden_pidm = rcresar_pidm
AND rcrapp1_pidm = rcresar_pidm
AND spriden_change_ind IS NULL
ORDER BY name
The second case statement is where I don't know exactly what it takes to get what I want.
Output should be like:
spriden_pidm name ID acg_elig_comm_code comm_code_description
«0000000000', ' 1111111111 ","John Doe","268", «rigorous HS race"»
If I take the second case statement it works great except that I do not have my comm_code description column. My question is how can I use my first statement value box to determine this column? I think that I need a case statement as I have, but I don't know how to reference the value of acg_elig_comm_code. Any help would be greatly appreciated. Thank you.

You cannot use the alias column in the query, even where it is set (except in the ORDER BY clause).
You can set the alias in a subquery and then use it in a great query, like this:WITH sub_q AS ( SELECT DISTINCT spriden_pidm,spriden_id id, spriden_last_name||', '||spriden_first_name name, CASE WHEN rcresar_comm_code_01 IN ('268','269','270') THEN rcresar_comm_code_01 WHEN rcresar_comm_code_02 IN ('268','269','270') THEN rcresar_comm_code_02 WHEN rcresar_comm_code_03 IN ('268','269','270') THEN rcresar_comm_code_03 WHEN rcresar_comm_code_04 IN ('268','269','270') THEN rcresar_comm_code_04 WHEN rcresar_comm_code_05 IN ('268','269','270') THEN rcresar_comm_code_05 WHEN rcresar_comm_code_06 IN ('268','269','270') THEN rcresar_comm_code_06 WHEN rcresar_comm_code_07 IN ('268','269','270') THEN rcresar_comm_code_07 WHEN rcresar_comm_code_08 IN ('268','269','270') THEN rcresar_comm_code_08 WHEN rcresar_comm_code_09 IN ('268','269','270') THEN rcresar_comm_code_09 WHEN rcresar_comm_code_10 IN ('268','269','270') THEN rcresar_comm_code_10 END acg_elig_comm_code -- Originally posted with , here (error) FROM spriden, rcresar, rcrapp1 WHERE (rcresar_comm_code_01 IN ('268','269','270') OR rcresar_comm_code_02 IN ('268','269','270') OR rcresar_comm_code_03 IN ('268','269','270') OR rcresar_comm_code_04 IN ('268','269','270') OR rcresar_comm_code_05 IN ('268','269','270') OR rcresar_comm_code_06 IN ('268','269','270') OR rcresar_comm_code_07 IN ('268','269','270') OR rcresar_comm_code_08 IN ('268','269','270') OR rcresar_comm_code_09 IN ('268','269','270') OR rcresar_comm_code_10 IN ('268','269','270')) AND rcresar_aidy_code = &aidy_code AND rcrapp1_aidy_code = rcresar_aidy_code AND rcrapp1_curr_rec_ind = 'Y' AND rcrapp1_seq_no = rcresar_seq_no AND spriden_pidm = rcresar_pidm AND rcrapp1_pidm = rcresar_pidm AND spriden_change_ind IS NULL ) SELECT sub_q.*, CASE WHEN acg_elig_comm_code = '268' THEN 'Rigorous HS course' WHEN acg_elig_comm_code = '269' THEN '2 or more AP or IB' WHEN acg_elig_comm_code = '270' THEN 'ACG possible' END comm_code_description FROM sub_q ORDER BY nameFurthermore, you might think to rearrange your table, so that you do not have 10 columns (rcresar_comm_code_01, rcresar_comm_code_02,...) that essentially do the same thing. The usual way to handle this kind of one-to-many relationship is to have all rcresar_comm_codes in a separate table, one per line, with a pointer to the table where you have them now.
