How to find common fields between two tables

Hi friends,
Is there any way to find out common fields between tables and linking the tables based on common fields.
Thanks and Regards,
Chitty.

Hi Chitty,
Try using joins it will give the fields which are only common to both the fields.
Here s an example,
SELECT mara~matnr
       marc~werks
INTO   TABLE t_material
FROM   mara AS mara INNER JOIN marc AS marc
ON     maramatnr = marcmatnr
WHERE mara~mtart = p_mtart.

Use User_tab_cols view to extract the result.
Try

Table created.
SQL> create table test4(id number(20),addr varchar2(200));
Table created.Now query user_tab_cols

Transaction to see common data between two tables

Is there any transaction to see common data between two tables with out creating views.
what is the transaction to see the link between two tables
regards
pavan

Hi,
Go to a transparent table for which you want to know the common fields, from there click the button GRAPHICS (shortcut Ctrl + Shift + F11) in the application tool bar. Then you are redirected to a list containing the tables belonging to the same group. There select whatever tables you would like to see and click COPY. A window will pop-up and will show the relationship between the fields of the tables in a flow chart format.
see to this link also.

please help with this.
thanks in advance
raja

Hi Raja,
Do it like this. loop the first table and read the second table.
Use where condition to satisfy the conditions.
Or
In your select query use joins. Like this.
SELECT mara~matnr
       marc~werks
INTO   TABLE t_material
FROM   mara AS mara INNER JOIN marc AS marc
ON     maramatnr = marcmatnr
WHERE mara~mtart = p_mtart.
Instead of MARA and MARC here use your tables.

12 x                         --- DIFFERENT
                       20 x ---- DIFFERENT
Query:
        Select * FROM
             ( (SELECT '1', ID, ID_TXT FROM TEST_1 MINUS SELECT '1', ID, ID_TXT FROM TEST_2)
              UNION
               (SELECT '2', ID, ID_TXT FROM TEST_2 MINUS SELECT '2', ID, ID_TXT FROM TEST_1) )
        Order By ID

How to get the 'link' between two tables

hi pple
i need to find out HOW two tables are related.
sample tables:
SHIPS ( HULL_ID [PK] , VESSEL_NAME, GROSS_TONNAGE )
EQUIPMENT ( E_ID [PK] , HULL_ID [FK frm SHIPS], DESC )
PARTS ( PART_ID [PK] , E_ID [PK, FK frm EQUIPMENT], MANUFACTURER_ID)
--> SHIPS and PARTS are some how related thro' EQUIPMENT.
i need to get this relationship:
Ships --> Equipment (E_ID) --> PARTS
currently, i can get the direct parent and child tables of a given table using:
SELECT lpad ( ' ', 2 * ( LEVEL - 1 ) ) || table_name as Child_Tables
FROM ALL_CONSTRAINTS
START WITH R_CONSTRAINT_NAME in
select constraint_name
from all_constraints
where table_name = '%table_name%'
and constraint_type = 'P'
CONNECT BY PRIOR CONSTRAINT_NAME = R_CONSTRAINT_NAME ;
To get ALL parents:
SELECT lpad ( ' ', 2 * ( LEVEL - 1 ) ) || table_name as Parent_Tables
FROM ALL_CONSTRAINTS
where owner = 'CHARTUSER'
START WITH CONSTRAINT_NAME in
select constraint_name
from all_constraints
where table_name = '%table_name%'
and constraint_type = 'R'
CONNECT BY PRIOR R_CONSTRAINT_NAME = CONSTRAINT_NAME ;
what i need to do is:
1) get children & parents of SHIPS
2) for each element of (1), get children, parents till i get PARTS
3) so, i will get EQUIPMENT and then, PARTS.
this wud be very expensive. my appln is in Java and i will need to call these functions - that makes it more complex. is there any simpler way out?
and my main problem is to find out WHAT attributes line two tables. this wudnt be a big deal if it were just simple parent-child tables. but, how do i find out the attributes that link PARTS and SHIPS table?
any ideas? -please help.
thanks in advance

Dear Srikanth,
This tables can be used once we come to know whether its a customer or vendor line item but in our case we using the GL account as reference have to knock off the entries.How we come to know that aginst the GL whether its a customer or vendor line item.. Then it should route to this table.
Suggest me if any options are there.

Finding unmatched records between two tables

Hi,
Suppose there are two tables - A and B and they have a couple of common key fields. I want to select those records from A which do not have a matching record in B. What will be most efficient way to do that?
Thank you.

Comparing Internal Tables: -
Internal tables can be compared with the operands that are used to compare other data objects. The most important criteria for comparing the internal table are the number of lines they contain. The larger the number of lines, the larger it is for comparisons. If the both the internal tables have same number of lines, then they are compared line by line. The operands used for comparisons are LE, LT, GE, GT, EQ, NE.
Except for EQ, the comparison stops at the first pair of components that identifies the condition false.

How to use common object from two tables with out join.

HI,
I have two tables called A & B In A table i have the following objects
1.weekend
2.S1(measure)
3.S2(measure)
4.S3(measure)
5.S4(measure)
And In B table i have followning columns
1.week end
2.p1(measure)
3.p2(measure)
4.p3(measure)
5.p4(measure)
Now in universe i created all the measure objects i.e.s1,s2,s3,s4,p1,p2,p3,p4 A.weekend,B.weekend.
instead of using week end two times i wnt to use only once because this is common in both table.
if i use join between these tables i am getting values fine
But With out join is there any thing to do in universe level to create common objects to use from both the tables..I tried using aggregate awareness but while reporting it is taking as two SQL.which is not synchronized.
Please help me on this ...

hi,
Although Weekend column is present in both tables, by creating a single Object in Universe, Universe can identify relationship with only table referenced in Object Creation.
So, there will be no identification of relationship with other table measures.
Obviously, you need to create 2 Weekend objects in Universe (in two classes).
Case 1: You need not join these two tables in Universe. When you create 2 Queries in WEBI, automatcially Weekend objects are synchronized (if both are of same datatype)
Case 2: If you join these two tables in Universe, Obviously,
your SQL may contain Weekend from Table1, measures from Table 2
or
your SQL may contain Weekend from Table2, measures from Table 1
Finally, You need to create 2 objects in Universe. But your query may contain a single Object based on Case 2.

So, what is your problem now?
You can join both the tables using a simple query and get the records.
select e1.empname, e2. empname from emp1 e1, emp2 e2 where
e1.empname = e2.empname and e1.empid = e2.empid

How can i merge data between two tables and then insert to another table

Hi ,
Could pls help me,
I have two tables i need to merge this tables for a single column then need to insert the records to a third table
Ex-
Suppose emp, dept two tables , merge this two tables for empid then insert that value to emp_dept table.
I am using oracle 10g.
Thanks

Hi,
too many values comes from the select clause. I stated you have to match the columns from the emp_dept table to the columns in the select. In my example I return all the columns of emp and dept, but I think you have only one empid column, the select for example will give 2, one empid from emp and one empid from dept. So best is to match:
insert into emp_dept
(column1,column2,column3,empid)
select emp.column1, emp.column2, dept.column3, emp.empid
from emp, dept
where emp.empid = dept.empidAbove is an example how you can match, so the number of columns in the insert should match with the number of columns coming from the select.
But better for us to help you is give your definitions of emp, dept and emp_dept.

How to find the difference between two date?

Hi,
I currently writing a date comparision program. Below is the idea analogy,
Currently i need to find how many day differences between 30 July 2003 and 22 June 2004. How can i use java to code it?
Thanks.

there doesn't seem to be a direct way but try this:int daysBetween = 0;
Calendar c = new GregorianCalendar(2004, Calendar.JULY, 30);
Calendar d = new GregorianCalendar(2003, Calendar.JUNE, 22);
while (c.get(Calendar.YEAR) != d.get(Calendar.YEAR)) {
daysBetween += 360;
d.add(Calendar.DAY_OF_YEAR, 360);
daysBetween += c.get(Calendar.DAY_OF_YEAR) - d.get(Calendar.DAY_OF_YEAR);This gives the correct result of 404 (= 8 days from June 22 to June 30 + 366 days between July 1 of 2003 and 2004 + 30 days from July 1 to July 30)

Here I have just returned a dummy value of 1.
create or replace
function testingFunction (<paramters if any>) return number
as
begin
update testTable set (wtime,ltime,etime)=(select extract(hour from (to_date('0930','HH24:MI')-to_date('1200','HH24MI')) day to second),
case when extract(hour from (to_date('0930','HH24:MI')-to_date('1200','HH24MI')) day to second) > 0830
then extract(hour from (to_date('1200','HH24:MI')-to_date('0830','HH24MI')) day to second)
else 0 end,
case when To_number('0900') > to_number('0815') then extract(hour from (to_date('0900','HH24:MI')-to_date('0815','HH24MI')) day to second)
else 0 end from dual);
return 1;
end;
A better option would be to create a stored procedure and call that. Just like the way I have done below
create or replace
procedure testingprocedure (<paramters if any>)
as
begin
update testTable set (wtime,ltime,etime)=(select extract(hour from (to_date('0930','HH24:MI')-to_date('1200','HH24MI')) day to second),
case when extract(hour from (to_date('0930','HH24:MI')-to_date('1200','HH24MI')) day to second) > 0830
then extract(hour from (to_date('1200','HH24:MI')-to_date('0830','HH24MI')) day to second)
else 0 end,
case when To_number('0900') > to_number('0815') then extract(hour from (to_date('0900','HH24:MI')-to_date('0815','HH24MI')) day to second)
else 0 end from dual);
end;
and call the procedure
testingprocedure(<parameters if any>);
