I have it here is the structure of the table
"CREATE TABLE"SCOTT" EMP_DET ".
(
ACTIVATE THE 'EMP_ID' NUMBER NOT NULL,
"EMP_NAME' VARCHAR2 (20 BYTE),
NUMBER OF "DEPT_ID",.
"KEY FOREIGN CONSTRAINT"EMP_DET_DEPT_MASTER_FK1"("DEPT_ID") REFERS TO"SCOTT" ENABLE DEPT_MASTER"("DEPT_ID")
)
"CREATE TABLE"SCOTT" DEPT_MASTER ".
(
ACTIVATE THE "DEPT_ID" NUMBER NOT NULL,
"DEPT_NAME" VARCHAR2 (20 BYTE),
'DEPT_MASTER_PK' CONSTRAINT PRIMARY KEY ("DEPT_ID")
)
Dept_master table given below
Dept_ID, Dept_name
1 X
2. IS
but emp_det contains no data.
but I need to see data like this in the emp_det table
Emp_det
Dept_ID emp_id, emp_name
missingdata 1-1
2. 2 missingdata
Concerning
Dale
Not sure this is what you are looking for.
SELECT DEPT_MASTER. DEPT_ID,
NVL (EMP_DET. EMP_ID, -(DEPT_MASTER. DEPT_ID)),
NVL (EMP_DET. EMP_NAME, "missing data"),
OF EMP_DET RIGHT OUTER JOIN DEPT_MASTER
ON EMP_DET. DEPT_ID = DEPT_MASTER. DEPT_ID;

How to load the child table by using a simple slider...?
How can I loa the child table by using a PL/SQL block cursor...
for example, I have a table of the source called method
EmpNo, empname, deptid deptname
and I have 2 tables of taget... EMP and Dept.
EMP
===
EmpNo, empname, deptid
Dept
====
deptID, deptname
Here, I want to load method for emp data and... Dept where dept does not contain data in double...
For now... I used the cursor and in the same cursor, I'm loading data first dept table and then to the emp table.
I use for dept, exceptional setting, which will manage a PK constraint violation error by doing nothing...
in this way, there will be no duplicates... but it is not advisable because I 15,00,000 lines in the method table.
Is there another way to do it?OK, I'd probably go with the method two insert, but as an alternative, here's a way to do it in a single insert:
create table emp_info as select 1 empno, 'a' empname, 101 deptid, 'aaa' deptname from dual union all select 2, 'b' empname, 201 deptid, 'bbb' deptname from dual union all select 3, 'c' empname, 101 deptid, 'aaa' deptname from dual union all select 4, 'd' empname, 101 deptid, 'aaa' deptname from dual union all select 5, 'e' empname, 301 deptid, 'ccc' deptname from dual; create table emp (empno number primary key, empname varchar2(3), deptid number); create table dept (deptid number primary key, deptname varchar2(3)); insert all WHEN rn = 1 THEN into dept (deptid, deptname) values (deptid, deptname) WHEN rn > 0 THEN into emp (empno, empname, deptid) values (empno, empname, deptid) select empno, empname, deptid, deptname, rn from (select empno, empname, deptid, deptname, row_number() over (partition by deptid order by empno) rn from emp_info); 8 rows inserted commit; select * from emp; EMPNO EMP DEPTID ---------- --- ---------- 1 a 101 3 c 101 4 d 101 2 b 201 5 e 301 select * from dept; DEPTID DEP ---------- --- 101 aaa 201 bbb 301 ccc
You must test these two methods to see which is more efficient.

Hello
y at - it (quesry) way to find the list of children tables for a given table.
tried to interview user_constraints and USER_CONS_COLUMNS, but not be able to find a way.
Thank youHello
You can use the query as follows - it will list the children tables and the FK name for table HR.JOBS:
Select
a.Owner, a.table_name, a.constraint_name
sys.all_constraints a.,
(select master, constraint_name from sys.all_constraints where owner = * 'HR' * and table_name = * "JOBS" * and constraint_type in ('P', 'U')) b
where
a.CONSTRAINT_TYPE = 'R' and a.r_constraint_name = b.constraint_name and a.r_owner = b.ownerIf you do not need name FK, then put separate:
Select
a.owner, separate a.table_name
sys.all_constraints a.,
(select master, constraint_name from sys.all_constraints where owner = 'HR' and table_name = 'JOBS' and constraint_type in ('P', 'U')) b
where
a.CONSTRAINT_TYPE = 'R' and a.r_constraint_name = b.constraint_name and a.r_owner = b.ownerPhilippe

How to get the a table check constraint.
I don't see the function to get forced check.
I try the table.getCheckConstraints () function
but I return nothing.Hello
table.getCheckConstraints () will return to check the constraints defined at the Table level in the Data Modeler.
You can also call column.getCheck (). This will return a check constraint defined on a column object in the Data Modeler.

How to get the default path of the data of a table space file
I used below the sql statement to create a table space:
CREATE A TABLESPACE DATAFILE AAA BBB SIZE 10 M AUTOEXTEND OFF...
Notice, I do not give a full path instead of a file name, and then ask questions relevant to tables
get the full path of the data file, assume that it's path below:
d:\oracle\...\BBB
So I don't think that there is a default path that oracle can use it to create the data file. My question
is how to get this default path before creating a table space.
Thank you very much.
Hello
I did similar simulations for you, then it could be seen easily:
SQL > Show parameter db_create_file_dest
VALUE OF TYPE NAME
------------------------------------ ----------- ------------------------------
db_create_file_dest chain
SQL > SELECT NAME, VALUE OF V$ PARAMETER
2 where lower (name) = "db_create_file_dest;
NAME
--------------------------------------------------------------------------------
VALUE
--------------------------------------------------------------------------------
db_create_file_dest
It has the value NULL. Then where my datafile is going?
SQL > create tablespace TEST datafile 'test01.dbf' size 10 M;
Created tablespace.
SQL > select file_name
2 of dba_data_files
3 where nom_tablespace = 'TEST ';
FILE_NAME
--------------------------------------------------------------------------------
/U01/app/Oracle/product/12.1.0/Db_1/DBS/Test01.dbf
When you check the alert logs, it will not show you the location of the data file. It will tell you what exactly you ran.
..
..
Completed: drop tablespace test whose content and data files
create tablespace datafile 'test01.dbf' size 10 M TEST
Completed: create tablespace TEST datafile 'test01.dbf' size 10 M
..
..
You can not SQL user * more? Well, I would say that, when you run the CREATE TABLESPACE command, is where you run the command:
SQL > select file_name
2 of dba_data_files
3 where nom_tablespace = 'TEST ';
FILE_NAME
--------------------------------------------------------------------------------
/U01/app/Oracle/product/12.1.0/Db_1/DBS/Test01.dbf
So, you should get the location of your data file. Alternatively, you can run the query in the parameter $ v so that you know your default data file location.
I hope this helps.
Thank you.
Kind regards

I used the example of library. I added the areas.
Then I tried to create the books.
The document says:
- In the main area (right) of the Data Modeler window, click the logical tab.
- Click the icon of the new entity.
But I don't see the logical TAB on the right side at all.
I see the Start Page. On the far right is the browser window. Basically, I see Messages - Log.
On the left side, I have the browser window.
Can someone tell me please how to get the logical TAB in the main area?
Thanks in advance.

How to get the second Monday of each month in a given date range?
In Oracle forms, how to get the second Monday of each month in a given date range?
I tried below using the query WITH the Clause, but it seems that WITH Clause does not work in Oracle forms. So is there another way to do this in Oracle forms?
WITH month_range AS
(
SELECT TO_DATE ('Dec 2013', 'Mon YYYY') AS first_month
, TO_DATE ('Mar 2014', 'Mon YYYY') AS last_month
OF the double

SELECT NEXT_DAY (6 + ADD_MONTHS (first_month

) AS second_monday
OF month_range
CONNECTION OF LEVEL < = 1 + MONTHS_BETWEEN (last_month, first_month)

Thanks in advance.
Good fishing, when the first day of the month is Thursday... So I changed the query accordingly... Try the below
SELECT CASE WHEN TO_CHAR (ADD_MONTHS (TRUNC(startdate,'MM'),(LEVEL-1)), 'DY') = 'game '.
THEN NEXT_DAY (ADD_MONTHS (TRUNC(startdate,'MM'),(LEVEL-1)), 'THU')
Of OTHER NEXT_DAY (ADD_MONTHS (TRUNC(startdate,'MM'),(LEVEL-1)), 'Game') + 7
END AS second_day
FROM (SELECT SYSDATE startdate,
SYSDATE + 300 enddate
THE DOUBLE)
CONNECT BY LEVEL<=>=>

Published by: 9999999 on 8 March 2013 04:30Use the IW format - it will make independent NLS solution. And all you need is truncated 7th day of each month using IW:
select sysdate current_date, trunc(trunc(sysdate,'mm') + 6,'iw') first_monday_the_month from dual / CURRENT_D FIRST_MON --------- --------- 08-MAR-13 04-MAR-13 SQL>
Here is the list of the first Monday of the month of this year:
with t as( select add_months(date '2013-1-1',level-1) dt from dual connect by level <= 12 ) select dt first_of_the_month, trunc(dt + 6,'iw') first_monday_the_month from t / FIRST_OF_ FIRST_MON --------- --------- 01-JAN-13 07-JAN-13 01-FEB-13 04-FEB-13 01-MAR-13 04-MAR-13 01-APR-13 01-APR-13 01-MAY-13 06-MAY-13 01-JUN-13 03-JUN-13 01-JUL-13 01-JUL-13 01-AUG-13 05-AUG-13 01-SEP-13 02-SEP-13 01-OCT-13 07-OCT-13 01-NOV-13 04-NOV-13 FIRST_OF_ FIRST_MON --------- --------- 01-DEC-13 02-DEC-13 12 rows selected.
