RETURN TO THE UPDATE QUERY CLAUSE

I have a request written in Postgres. This will pick up the records in the table job_information with the State, as provided by the application (ex: "READY_TO_RUN") and with limit of records like the one provided by the application (ex: 100), then updates the job_information with app get (ex: "ACHIEVEMENTS") and returns that defined (means, returns the data table job_information total for these got put to date with the given State) records for the use of the application.

Can someone give me advice on the translation in Oracle? Thank you!!

Query in Postgres

UPDATE job_information AS J1
SET status=?
FROM
  (SELECT job_name,
    job_group,
    created_date
  FROM job_information
  WHERE status           =?
  AND CURRENT_TIMESTAMP >= scheduled_execution_time
  ORDER BY scheduled_execution_time limit ?
  ) AS J2
WHERE J1.job_name   = J2.job_name
AND J1.job_group    = J2.job_group
AND J1.created_date = J2.created_date RETURNING *;

Example of a query (in postgres):

UPDATE job_information AS J1
SET status= 'ACQUIRED'
FROM
  (SELECT job_name,
    job_group,
    created_date
  FROM job_information
  WHERE status           = 'READY_TO_RUN'
  AND CURRENT_TIMESTAMP >= scheduled_execution_time
  ORDER BY scheduled_execution_time limit 100
  ) AS J2
WHERE J1.job_name   = J2.job_name
AND J1.job_group    = J2.job_group
AND J1.created_date = J2.created_date RETURNING *;

Oracle SQL - query, I wrote it is not working

UPDATE JOB_INFORMATION SET STATUS=
(
WITH J2 as (
                        select job_name, job_group, created_date from (SELECT job_name, job_group, created_date FROM job_information WHERE status= :b and current_timestamp >= scheduled_execution_time order by scheduled_execution_time ) where rownum<= :c
            )
SELECT distinct :a FROM JOB_INFORMATION J1, J2 WHERE J1.job_name = J2.job_name AND J1.job_group = J2.job_group AND J1.created_date = J2.created_date
)
RETURNING * FROM JOB_INFORMATION BULK COLLECT INTO SOMETHING ;

create or replace package test_pack

as

type r_tab is (record

type t_tab is table of the r_tab;

function test_func (v_status_o VARCHAR, v_status_i VARCHAR) - USE VARCHAR2

T_tab RETURN PIPELINED;

end;

create or replace the BODY of PACKAGE as test_pack

function test_func (v_status_o VARCHAR2, v_status_i VARCHAR2) return t_tab pipelined as

because me in 1... loop v_tab. Count

pipe row (v_tab (i));

end loop;

Return in the MERGE statement clause

Hello

I use Oracle 10 g Version

I tried the code using UPDATE with return Clause & MERGER with return below Clause.

I have not found ANY error while working with the UPDATE statement. Here is the code with the UPDATE statement

DECLARE
   TYPE empno_list IS TABLE OF emp.empno%TYPE;
   vempno_list   empno_list;
BEGIN
      UPDATE emp
         SET comm = 11
       WHERE deptno IN (SELECT deptno FROM dept)
   RETURNING empno
        BULK COLLECT INTO vempno_list;
   FOR i IN vempno_list.FIRST .. vempno_list.LAST
   LOOP
      DBMS_OUTPUT.put_line ('Values of EMP ' || vempno_list (i));
   END LOOP;
END;

But PL/SQL error: ORA-00933: SQL not correctly completed command when you work with the MERGE statement

declare 
 type empno_list  is  table of emp.empno%type;
 vempno_list empno_list;
begin                
   merge into emp tgt 
      using dept src
        on (src.deptno =tgt.deptno)
        when matched then 
         update set tgt.comm=12
       returning tgt.empno bulk collect into vempno_list ;
       
        for i in vempno_list.first .. vempno_list.last loop
                dbms_output.put_line('Values of EMP '||vempno_list(i) ) ;
        end loop;
end;

Please suggest me

Probably because BACK IN clause does not belong to the MERGE statement. It is available only for INSERT, UPDATE, and DELETE. Here's the quote from Oracle Documentation:

The static method RETURNING INTO article belongs to a DELETE , INSERT , or UPDATE statement. The dynamic RETURNING INTO article belongs to a EXECUTE IMMEDIATE statement.

And here is the link.

Back IN the Clause

It will be useful.

return the empty record only when no results not returned by the main query
It is a question of SQL (not PL/SQL)...

Let's say I have the following text:

Full_name SELECT NULL, NULL, NULL last_update_date address
OF the double
UNION ALL
SELECT full_name, address, last_update_date
Employees
WHEN TRUNC (sysdate) = TRUNC (last_update_date)

If the second part of the query retrieves no rows, it works beautifully and I get a blank line; However, if the second part of the query returns records, I get a blank line over my dataset I want.

How can I create a SQL statement that executes only the first query (before the union all) when no result is returned from the second. Also, I don't want to exceute the query twice only if I can get a count of the records because my actual query is much more complex than the example I've provided here.

Thanks in advance!
Emily
Hello

You can try to use a subquery factoring (WITH clause)
The query is executed only once, the query results are cached in memory or in a temporary table.
and you can view these results several times in the main query:
```
WITH second_query AS (
  -- your second query here
  SELECT full_name, address, last_update_date
  FROM employees
  WHERE TRUNC(sysdate)=TRUNC(last_update_date)
)
SELECT full_name, address, last_update_date
FROM second_query
UNION ALL
SELECT NULL full_name, NULL address, NULL last_update_date
FROM dual
WHERE NOT EXISTS ( SELECT 1 FROM second_query)
```

Not the rows returned by the spatial query wrapped in SELECT * FROM...

Hello

When you run a query with SDO_EQUAL sub, I get a very strange behavior. The SDO_EQUAL query on its own works very well, but if I wrap in SELECT * from there, I get no results. If I wrap SDO_ANYINTERACT in SELECT * from there, I get the expected result.

It seems like the spatial index is used during the execution of the ordinary, but not when SDO_EQUAL request wrapped in SELECT * FROM. Weird. The spatial index is also not used when SDO_ANYINTERACT is wrapped in SELECT * FROM... so I don't know why that returns the correct answer.

I get this problem on 11.2.0.2 on Red Hat Linux 64-bit and 11.2.0.1 on Windows XP 32-bit (i.e., all versions of 11g I've tried). The query works as expected on 10.2.0.5 on Windows Server 2003 64-bit.

Any ideas?

The UPDATE query help
I'm on 10G.

Something is weird. Each customer_id to table X is from the subquery. Basically by train to fill the column of SUSPICION in X to a value of H when there are name/store is from the subquery using the customer_id.

When I run just the subquery returns 287 matches (and all these 287 X is), but when I try to UPDATE X only update the 260 H lines, but should 287? 27 never update, why? The customer_id are distinct or not NULL values.

What I am doing wrong?

Like I said I have selected everything from (subquery), I pasted in Excel. I chose all the customer_ids of X and when I do a VLOOKUP, everything matches, but the query updates only 260 and 287 not? :- )

UPDATE PROSPECTS_FEB_TEST X
SET X.HINT = 'H' WHERE X.customer_id IN

(SELECT a.customer_id
PROSPECTS OF A, B CONNECTED
WHERE B.LAST_NAME = A.NAME_LAST
AND B.FIRST_NAME = A.NAME_FIRST
AND B.STORE = A.STORE);
What you get from this?
```
SELECT COUNT(DISTINCT a.customer_id)
FROM prospects a, connected b
WHERE b.last_name = a.name_last and
      b.first_name = a.name_first and
      b.store = a.store
```
Is customer_id a numeric field or a varchar2? If it's a varchar2, could their space having in one of the other tables?

Question about the rollback segment when you perform the update

Undo segment is to keep data ACI (not D). I read that it taken from the book of certification, when the update is running, all the other session will be redirected to cancel the segment to get the original version of the data. Is the rollback segment just a copy of the original version of the data? Or it's the query to return data to the original version?
For example, the original data are:
ID name address
1 Kevin Toronto
Then I run the update query:
update user name = 'Tom' where id = 1;
What is in the segment of cancellation then?
There ' 1, Kevin, Toronto'.
or
"update users set name = 'Kevin' where id = 1"?
Thank you
Kevin

This is another UPDATE statement that will set back to the original value NAME; which can be used to RESTORE the DML.

Dynamic display of columns in the pivot query
I have a table called STUDENT_SCORE. I need to display the avarage score/month for 2 years and the monthly score until today "month.

Then assume that it is April 2009. The report will look like

Hello

The script below produces what you want (as far as I can tell, without your desired results).

Student_score_smry subquery Gets the year and monthly averages of student_score.
It is completely static: it always produces 11 monthly columns (from January to November) and the names of columns hardcoded (m01 through m11).
For dynamic column names you need, I used SQL * COLUMN more orders.
To get the variable number of monthly columns you need, SELECT from the main query clause uses a script under (dynamic_month.sql) to only show the correct number (which can be 0).

The student_score_wk_smry of subquery retrieves the weekly averages of the student_score_wk.
He, too, is completely static: it always produces 6 weekly columns with names hardcoded (w1 through w6).

There are four preliminary motions, that write two scripts under:
Prelimiary C1, C2 and C3 queries write orders of COLUMN for annual, monthly and weekly columns in dynamic_columns.sql
Preliminary motion M written between 0 and 11 items in SELECT-clause in sub-script dynamic_month.sql

The main script is:

Export as .xls. Classic report type: SQL (body of function from PL/SQL returning the SQL) query

Hey guys,.
I'm using version 4.2.6 apex. The theme is 26.
IM also using Listener Oracle APEX.
I can print my classic report in PDF or CSV format.
But I need to export it as a .xls extension.
Report type: SQL (body of function from PL/SQL returning the SQL) query
I need is like this cause my 'where' clause type is dynamic.

Look at using this method: Tom's Blog: a non-standard export excel 2010 (.xlsx)

I do something similar for downloads to excel in my projects...

Thank you

Subselect query returns "invalid identifier", but the nested query return lines

I don't think it's a general SQL question.
Select * from persons where person_id in)
Select person_id with people whose name = 'Obama' - subquery
) and age > 18;
When I run the subquery, I get:
ORA-00904: "PERSON_ID": invalid identifier
00904, 00000 - '% s: invalid identifier '.
* Cause:
* Action:
Error on line: column 5: 8
This is because the table people do not have the person_id field.
But when I run the nested together query it returns all the lines in people with the AGE greater than 18.
How is he succeeds when the subquery is obviously wrong?

Yes - this is a general SQL question and ask often enough.

Correlated subqueries depend on the inner query, be able to see and access to the columns of the outer query. Normally see you referenced in the WHERE clause of the subquery and not in the SELECT clause, but the reference is valid in both places. This works because the columns of the tables in the main query are accessible in the subquery. "Person_id" is probably a column in the table 'people '.

Which can be a cause of problems 'odd' when the column (in your case "person_id") is more of a table.

Use an alias in the subquery in the subquery and you will find that it will not succeed.

See these two articles AskTom where he addresses this specific issue

Disable the generation of report when there are no returned by the query
I would like to write a preliminary report trigger that disables reports generation when my main query in my data model will return no data. If possible, I would like to reuse the same query in the data model from the writing of a motion to double again.

Thank you all
Create a view for the main request. In this case, you just have to do it in the front trigger of the report:
```
select count(*)
into my_var
from my_view
where ...;

if my_var =  0 then
   return false;
else
   return true;
end if;
```
In where clause you can use the same settings as in your main report query.

ID	name	address
1	Kevin	Toronto

ID	name	address
1	Kevin	Toronto

sql Update query after matching with the string

I am trying to reach the query that updates a table column with the value of the other table, after that he finds an exact match.

So here's the table data and sample to create.

create table code1 
(
    codeid number,
    codedesc varchar2(60)
);

Insert into code1 values ( 1,'R1 CONTRACTS');

Insert into code1 values ( 2,'R2 CONTRACTS');

Insert into code1 values ( 3,'R3 CONTRACTS');

Insert into code1 values ( 4,'R5 CONTRACTS');

Insert into code1 values ( 5,'R9 CONTRACTS');

Insert into code1 values ( 6,'R10 CONTRACTS');

create table table1 
(   
    tablekey number,
    prefix  varchar2(25),
    codedesc    varchar2(60)
);

Insert into table1(tablekey,prefix) values (1,'1001PAC');

Insert into table1(tablekey,prefix) values (2,'1001MXT');

Insert into table1(tablekey,prefix) values (3,'1002PAE');

Insert into table1(tablekey,prefix) values (4,'1003PCS');

Insert into table1(tablekey,prefix) values (5,'1004BDX');

Insert into table1(tablekey,prefix) values (6,'1005PAC');

Insert into table1(tablekey,prefix) values (7,'1006PAC');

Insert into table1(tablekey,prefix) values (8,'1007LDR');

Insert into table1(tablekey,prefix) values (9,'1009LCR');

Insert into table1(tablekey,prefix) values (10,'1010LBR');

Insert into table1(tablekey,prefix) values (11,'ABCDEF');

I'm writing a query that would update the value of column - codedesc (currently Null) of the table1 table: after it is a string of column - table code1 codedesc.

The logic for the match is, - take - 2nd column of table-codedesc code value and get 2 characters. For example, when the string is - R1 CONTRACTS, the string will be 1. (Select substr ("R1 CONTRACTS, 2, 2) of the double). -Output will be 1.

Now,.
Look in table 1 for the 3rd position of the prefix that corresponds to the string returned by the query above. So, if the prefix is '1001PAC', it should look for 2 value of figures from the 3rd position. So, in this case it will be 01. Digitally 01 and 1 are equal, then the match is found for this line in the table1 table, so we will need to update the value of the column codedesc with the "contracts of R1.

Appreciate your help.

Hello

You want to avoid TO_NUMBER, given that will cause an error if even a line has a number no (except space) in the wrong place.
Use RTRIM to remove extra spaces at the end of the match_key and LPAD to add '0', if necessary, at the beginning:

MERGE INTO     table1          dst
USING   (
          SELECT  LPAD ( RTRIM ( SUBSTR ( codedesc
                                 , 2
                               , 2
                               )
                          )
                     , 2
                     , '0'
                     )          AS match_key
          ,     codedesc
          FROM     code1
     )               src
ON     (src.match_key     = SUBSTR ( dst.prefix
                       , 3
                     , 2
                     )
     )
WHEN MATCHED THEN UPDATE
     SET     dst.codedesc     = src.codedesc
;

Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!
