Compare two rows in the same table
Hi allI need to compare two rows in the same table, I don't know hoe to do it in pl/sql. Please help me on this.
example:
price of ro TR
xya0001 AMA.7 12
xya0003 ama6 14
xya0004 AMA.7 16
in table b is a unique value for each line, I need to compare the price column and see if the first value is less than or greater than the following value and, if there is more to put the corresponding value of br to a variable, and if it is less, put the corresponding value of the br to another variable. I don't know a method to do this, as I'm new to pl/sql. Please help me in this
for data in(select tr,br,price, lag(price) over ( order by tr) newcol
from yourtable)
loop
if nvl(data.newcol,0) > data.price then
variable1:=data.br;
else
varable2:=data.br;
end if;
end loop;

Mr President.
My worm jdev is 12.2.1
How to enter two rows at the same time with different default values that only the first line to use see?
Suppose I have a table with four fields as below
"DEBIT" VARCHAR2(7) , "DRNAME" VARCHAR2(50), "CREDIT" VARCHAR2(7) , "CRNAME" VARCHAR2(50),
Now I want that when I click on a button (create an insert) to create the first line with the default values below
So if I click on the button and then validate the second row with different values is also inserted on commit.
The value of the second row are like the picture below
But the second row should be invisible. It could be achieved by adding vc in the vo.
The difficult part in my question is therefore, to add the second row with the new default values.
Because I already added default values in the first row.
Now how to add second time default values.

My code to get my goal is
First line of code is

If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?
My two fields are FLOW AND DR_NAME
FLOW = ACCT_ID
DR_NAME = ACCT_NAME
I created with success of LOV for these fields.
First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.
How can I report these lov, it's that when I change my acct_id then acct_name also change
I have these two tables

comparing string values in the same table
I have a table with ID (14 digit string values) starting with "A". Ex: A21849B1020792. There may be a different ID with the same substring 'B1020792' in the same table, example: A12349B1020792. If this happens, the ID of the last creation date of must be returned in the result. In other words, comparison is done on the same table. "In the example provided, say A12349B1020792 has the date of 1 January 2015 'and A21849B1020792 has date February 1, 2015", since A21849B1020792 has the most recent date, the result must contain only A21849B1020792.

A12345B1234567 01/03/2015
A43567B1234567 01/04/2015
Here's the query I used:substr (a.id, 7) select sc, max (a.create_date) cd1
of table a, table b
where a.id! = b.id
and substr (a.id, 7) = substr (b.id, 7)

There is one thing that I'm not able to do with my request, that is, be able to get real IDs list and not list of substrings. If I added a.id column in the select clause and the group by clause, the query includes both by substr (a.id, 7) and a.id and as a result, the query returns four lines as below:
substr (a.id, 7) select sc, max (a.create_date) cd1, a.id ID
of table a, table b
where a.id! = b.id

If it makes sense to treat the first 6 characters of the ID separately from the rest of the id in this problem, maybe it makes sense to store those two parts of the id in two different columns. Relational databases work best when each column of each row contains 1 single piece of data (at most). It is so fundamental to the design of table that he called the first normal form.
Given that the two parts are stored in column 1, so you can something like this Request Top - N:
WITH got_r_num AS
(
SELECT r.id
r.create_date AS cd1
, RANK () OVER (PARTITION OF SUBSTR (r.id, 7))
ORDER BY r.create_date DESC
) AS r_num
FROM table_x g - g for data values
JOIN table_x r - r for related values
ON SUBSTR (r.id, 7) = SUBSTR (g.id, 7)
WHERE g.id IN ('A12349B1020792'
, "A21849B1020792".
, "A12345B1234567".
, "A43567B1234567".
)
- AND g.id LIKE 'A %' - if necessary. The above condition ensures already g.id start with "A".
AND r.id LIKE 'a % '.
)
SELECT id, create_date
OF got_r_num
WHERE r_num = 1
;
If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test this.

Update of several rows of the same table using trigger
Hello
I have the following table
---------------------------------------------------------------------------------------------------------
CREATE TABLE ATT_PERMISSIONS ( DATE OF PRMONTHYR, EMPID NUMBER (10) DEFAULT VALUE 0 , FROMDATETIME DATE , TODMTFDATETIME DATE , NUMBER OF PERMMINS (3), SSLINASTRETCH NUMBER (3).
PERMATTINELIGIBLE NUMBER (1) DEFAULT VALUE 0 ); ------------------------------------------------------------------------------------------------------
I want to update the column PERMATTINELIGIBLE in the same table when each line is inserted.
I created following trigger for that
CREATE OR REPLACE TRIGGER SSL_AFTER_UPDATE AFTER UPDATE ON ATT_PERMISSIONS
FOR EACH LINE
BEGIN
Update ATT_PERMISSIONS set PERMATTINELIGIBLE =
(
SELECT THE CHECK BOX
WHEN PERMMINS < = 60
or
(
PERMMINS < = SSLINASTRETCH
AND
COUNT (CASE WHEN PERMMINS = 0 THEN NULL OTHERWISE 1 END)
COURSES (PARTITION BY empid, prmonthyr) < = 1
)
THEN 1
0 OTHERWISE
END
FROM ATT_PERMISSIONS where prmonthyr =:new.prmonthyr, empid =:new.empid
) where prmonthyr =:new.prmonthyr, empid =:new.empid;
END;
---------------------------------------------------------------------------------------------------
That is to say.
When a row is inserted the PERMATTINELIGIBLE of all records for this employee for the month is recalculated.
There would be only two or three records for an employee for a month.
PERMMINS is the number of minutes to use as short leave.
If it is less than 60 is eligible for the bonus to attendance for this employee.
If this isn't normally the date is not eligible for the attendance for this employee premium.
but an exception is that if a short leaves of DISP employee allowed a month (IE. ( SSLINASTRETCH ) in a straight line, IE. one day, that day is eligible for the bonus of presence.
That is to say. Why the number of short leaves in a month is taken. If it's one and done minutes use is lower to SSLINASTRETCH, then the day is eligible for the attendance bonus.
But when I try to create the trigger I get error, PL/SQL: ORA-00907: missing a right parenthesis.
Help, please

No - you do NOT want to do in a trigger.
You cannot query the same table that the trigger is activated on. -C' is a MUTANT and you will get an exception.
When a row is inserted is recalculated to the PERMATTINELIGIBLE of all the records for that employee for that month.

You can not do in a trigger. Even if correct you this error of syntax, you will get the exception that I mentioned above.
Oracle is a multi-user system. Other users can modify the same table that you use.
So even if you could try to interview "all the records for this employee" some of them may be locked if other users access them. Also, an insert statement could try to insert two rows for an employee and the trigger could not have seen the other lines still.
If you want to work with data SETS (all records for an employee), you must write the PL/SQL code that LOCKS all lines updated to prevent others to interfere.
Then you make your operations but NOT in a trigger. Perform inserts and then use an UPDATE query to set this value.
Then VALIDATE to unlock the lines.

Update lines with the info from the other rows in the same Table.
I'm trying to update the lines with the information of the same table. The table is loaded with information from a report that runs and there must be a new entry every month, but I would like to bring some of the info from the last month. This statement below works but updates all rows in the new load table and in my test case, I only did a few game only like 5 files need to get updates. It is an example of what I'm trying to do. If I add this (C2. COL_INVC_ID = C1. COL_INVC_ID) until the last "* where *" statement get an invalid identifier for 'C2 '. COL_INVC_ID ". So what I'm doing wrong here? How can I update only the lines where also in recent months run?

When I ask of blockA and it worked, then I go to blockB and modify data, and save, there is no problem. But when I do not run the query of blockA or if the query did not return any results, I go to blockB and change some data then save, I got this error. The cursor then go to first blockA point. So now, I have to delete this empty line before the Save.
Any suggestion?you set a few initial values programmatically for a block?
in this case, the status changes to INSERT and you will get this message.
You can check the staus with GET_RECORD_PROPERTY (1, "A BLOCK", STATUS), e.g. with the trigger KEY-COMMIT. -

MERGE INTO table_x dst USING ( SELECT keyid , effectivedate , LEAD (effectivedate) OVER ( PARTITION BY keyid ORDER BY activedate ) AS inactivedate ) src WHEN MATCHED THEN UPDATE ON ( src.id = dst.id AND src.effectivedate = dst.effectivedate ) SET dst.inactivedate = src.inactivedate ;I want to have a select script which shows KeyID EffectiveDate InactiveDate New_InactiveDate 1 01/01/2013 01/02/2013 1 01/02/2013 01/03/2013 1 01/03/2013 2 12/31/2012 01/02/2013 2 01/02/2013 01/03/2013 2 01/03/2013Once that you have done the above MERGER, it is simply:
SELECT * FROM table_x ORDER BY keyid , effectivedate ;If you do not have sthe FUSION, then see the query in the USING clause of the MERGER.
I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and the results you want from this data.
In the case of a DML (UPDATE), for example, the sample data should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

Compare several records in the same table
Hello, I m writing a bat file so I can export information that I question.
I have an automatic integration which checks from time to time if there is no new client´s and generates a trigger.
If an error levonorgestrol I the process is repeated until the client is located in the database.
I can't create tables or change the structure.
My problem is that I need to compare the record more updated with the CLIENT_ID field
Let me give you an example:
Table A
ERROR_MESSAGE CREATEDUSERID CLIENT_ID
0 success 01/01/2009
1 error 01/01/2009
2 success 01/01/2009
1 success 01/02/2009
3 success 01/02/2009
4 error 01/02/2009
I need to compare "1" client created on 01/01/2009 this error gived with new records to see if there's success and my
query should only return the client_ID '4' and export with sqlplus
Could you please help me?Hello
It works very well with my data.
What data do you use? After a few lines of sample data (CREATE TABLE AS executable... or INSERT... statements are best) that give you wrong results.Make sure that everything is spelled correctly.
For example, roughly halfway through the query, you sayand io.status = 'Erro'and at the end you say
having max(decode(io.status, 'Error', 1, 2)) ...That is the same ("Error" or "Error") in both places?

end loop;
commit;
end;
I got totally confused and do not know what to do next
Any help and the best guide is appreciatedAnalytics can also be used (assuming that you store dates as dates, ORDER BY working properly)
create table t(org varchar2(10),mon date, cont number); insert into t(org,mon,cont) values ('Kano',to_date('201101','YYYYMM'),200000); insert into t(org,mon,cont) values ('KADUNA',to_date('201101','YYYYMM'),300000); insert into t(org,mon,cont) values ('Kano',to_date('201102','YYYYMM'),300000); insert into t(org,mon,cont) values ('KADUNA',to_date('201102','YYYYMM'),200000); commit; select * from t; ORG MON CONT ---------- ---------------------- ---- Kano 01-JAN-2011 00:00:00 200000 KADUNA 01-JAN-2011 00:00:00 300000 Kano 01-FEB-2011 00:00:00 300000 KADUNA 01-FEB-2011 00:00:00 200000 select org,cont1 start_month,cont2 end_month,cont1-cont2 difference from ( select org,mon,cont cont1, lead(cont) over (partition by org order by mon) as cont2 from t where mon in (to_date('201101','YYYYMM'),to_date('201102','YYYYMM')) ) where cont2 is not null; ORG START_MONTH END_MONTH DIFFERENCE ---------- ----------- --------- ---------- KADUNA 300000 200000 100000 Kano 200000 300000 -100000 -
ViewCriteria comparing two columns of the table to create
Anyone know how I can create a ViewCriteria where clause that compares the two columns of the same table?
For example if I had two columns of integers (MINSAL and MAXSAL) and wanted to see if they are equal. Normally, I would do the following SQL below.
SELECT * EMPL
WHERE MINSAL = MAXSALTry to link any of them to an expression of groovy.

How to update columns with the value of other lines in the same table
Hello
I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
create table TB_test (number 4 myId, crtTs date, date of MDPU);
insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
After you run the SQL code, I would like to have the following result:
1, 20110101, 20110201
1, 20110201, 20110301
1, 20110301, null
2, 20110901, 20110902
2, 20110902, null
Thanks for your suggestion.I guess you need this, otherwise please explain logic correctly:
SQL> merge into tb_test t 2 using ( 3 select rowid as rid 4 , lead(crtts) over(partition by myid order by crtts) as updts 5 from tb_test 6 ) v 7 on (t.rowid = v.rid) 8 when matched then update 9 set t.updts = v.updts 10 ; 5 rows merged. SQL> select * from tb_test order by 1,2; MYID CRTTS UPDTS ---------- --------- --------- 1 01-JAN-11 01-FEB-11 1 01-FEB-11 01-MAR-11 1 01-MAR-11 2 01-SEP-11 02-SEP-11 2 02-SEP-11 -
Comparing the same tables of two schemas
I had already posted a similair on this thread. So, I thought I would start a new thread on this to avoid confusion
I want to generate a report that shows the difference in the data type of the columns in the same table in two different patterns.
The query using LESS shows the difference below.
But, since it is a report, I want to see the form of results the two schemas that has column of different data types with the same names of tablecreate table SCOTT.mytab1 (empid number); create table HR.mytab1 (empid varchar2(34)); SELECT table_name, column_name, OWNER schema, data_type FROM dba_tab_cols where owner = 'SCOTT' AND TABLE_NAME = 'MYTAB1' MINUS SELECT table_name, column_name, OWNER schema, data_type FROM dba_tab_cols where owner = 'HR' AND TABLE_NAME = 'MYTAB1' Result: TABLE_NAME COLUMN_NAME SCHEMA DATA_TYPE --------------- --------------- ---------- ------------ MYTAB1 EMPID SCOTT NUMBER
Expected results:
Anyway I could do this?TABLE_NAME COLUMN_NAME SCHEMA DATA_TYPE --------------- --------------- ---------- ------------ MYTAB1 EMPID SCOTT NUMBER MYTAB1 EMPID HR VARCHAR2Why not get a single line with two types of data:
select a.table_name, a.column_name, a.data_type schema1_type, b.data_type schema2_type from all_tab_columns a, all_tab_columns b where a.owner = 'SCOTT' and b.owner = 'HR' and a.table_name=b.table_name and a.column_name=b.column_name and a.data_type!=b.data_type;This extracted single query columns present on the two schemas but with different data types. These columns only on one of the two schemas are not extracted.
