问题 I have stored procedure which executes another stored procedure several times. I need union and return data, which I have after executing second procedure. Can I in some way union data from several cursors into one another cursor? It is possible without temporary tables or table-like datatype? EDIT: Cursor count for union actually is n (where n is 1, 2, 3, etc, detecting by another procedure). For example: CREATE OR REPLACE PROCEDURE proc_data ( data_out OUT SYS_REFCURSOR ) IS BEGIN OPEN data

问题 I am using SQL Developer 3.1.07 on an 11g database When I use listagg to extract multiple values from a field I get a space between each character in the results for the listagg column. The query returns all the values I expect to see, it's just the extra spaces that are driving me nuts. Any thoughts? Here is one query that I have used, but it happens everytime I use listagg in a query: select a.personnum Emp_ID , a.personfullname Name , a.companyhiredtm Hire_Date , a.employmentstatus Status

问题 I've been struggling to solve a few tricky problems in SQL where I need to infer asset utilisation from event intervals, and have just learned about Allen's Interval Algebra, which seems to be the key to solving these problems. The algebra describes 13 kinds of relationships between intervals, and the image below shows the first seven, with the rest being the inverse (i.e. y before x, y meets x, etc) But I'm having trouble finding out how to implement the relevant operations. Given my sample

问题 my table has the following strucuture empno empname loan ref amount 1 abc 123 100 1 abc 456 200. i.e an employee can avail two loans(say car and scooter). The output expected: empno empname loan ref1 amt loanref2 amt 1 abc 120 100 456 200 to avoid duplicate empno repeating. How to go about it in sql??? 回答1: Concerning the previous comments on table design - there is, in fact, a redundancy in the table; you could store the empname in another table, which you would join with your table here to

问题 Oracle 11g. I figured out that if I add NOENTITYESCAPING to the XMLELEMENT function, it nicely turns off entity escaping. However, when I then pass the result to EXTRACT the escaping seems to come back again. select xmlelement(NOENTITYESCAPING e,id,'->') from (select level as id from dual connect by level < 6) XMLELEMENT(NOENTITYESCAPINGE,ID,'->') --------------------------------------- <E>1-></E> <E>2-></E> <E>3-></E> <E>4-></E> <E>5-></E> Now, adding EXTRACT : select xmlelement

问题 I want to create an Oracle DBMS Job that runs every week day (not on weekends) from 09:00 to 20:00 every 10 min. I wonder if I can do that in the FREQ parameter of the job definition or I have to create a New Maintenance Window . It seems that with the solution proposed, the job runs at 9 and 20 only, and after first execution, when I run this query select owner, job_name, next_run_date from dba_scheduler_jobs where JOB_NAME = 'GET_INVOICES_JOB'; I got 09/10/17 20:01:27,000000000 EUROPE

问题 I am attempting to use an Oracle global temporary table without physically creating a table in the database. The following code is not working. Can someone please explain the proper way to use global temporary tables? declare global temporary table my_temp_table(column1 number) on commit preserve rows; begin insert into my_temp_table (column1) values (1); select * from my_temp_table; end; 回答1: Try the below using execute immediate: it uses exception handler to bypass if table already exists;
