Pl/sql block to retrieve information from three tables.

Hi Everyone,
I have three tables. Student table, bookDetails table and bookIssue records table.
This is my question
Write a plsql block that has to display bookid, booktitle, student_name, earliest issue date and recent issue date taking the input of Student id.

Getting information from three tables

I have three tables, FIRST, SECOND and THIRD. There are other columns
than the ones I show here, so the tables are not union compatible
FIRST
(VALUE_TWO , VALUE_ONE)
SECOND
(VALUE_TWO, VALUE_THREE)
THIRD
(VALUE_THREE, VALUE_FOUR)
How can I display: all VALUE_THREE's from THIRD
where VALUE_FOUR = 'x'
as well as
all VALUE_TWO's from SECOND where VALUE_THREE
is equal to the list of VALUE_THREE's I got in the first step
as well as
all VALUE_ONE's from FIRST where VALUE_TWO
is equal to the list of VALUE_TWO's I got in the second step
If I run the following
SELECT VALUE_ONE
FROM FIRST
WHERE VALUE_TWO IN
(SELECT VALUE_TWO
FROM SECOND
WHERE VALUE_THREE IN
(SELECT VALUE_THREE
FROM THIRD
WHERE VALUE_FOUR = 'x'))
This just displays VALUE_ONE.

is this what you are looking for
select value_three
from third
where value_four='X'
union all
select value_two
from second
where value_three in (select value_three from third where value_four='X')
union all
select value_one
from first
where value_two in (select value_two from second where value_three in (select value_three from third where value_four='X'))
if so and you happen to be on 10 g you can do it this way too
SELECT A
FROM (
select value_one A,value_two B from first
union all
select value_two,value_three from second
union all
select value_three,value_four from third)
CONNECT BY PRIOR A=B
START WITH B='X'

Retrieving data from 3 tables

Hi,
I am working on a report where I have to retrieve data from 3 tables(marc,mara,makt).For this I have used 3 select statements for retriving data from 3 tables.There r some fields which r not present in marc table where as present in mara and makt tables.So added thos fields in marc internal table t_marc.I have looped at marc table and used the read statement to read the data from mara table using the key field matnr from both the tables.This read statement is giving the sy-subrc value as 4.Could u pls tell me why this is happening?I am sending my code.
SELECT matnr
       werks
       pstat
       lvorm
FROM marc
INTO TABLE t_marc
PACKAGE SIZE 500
WHERE matnr IN s_matnr
AND   werks IN s_werks.
IF NOT t_marc[] IS INITIAL.
SELECT matnr
        ersda
        laeda
        meins
   FROM mara
   INTO TABLE t_mara
   FOR ALL ENTRIES IN t_marc
   WHERE matnr = t_marc-matnr
   AND   ersda IN s_ersda
   AND   laeda IN s_laeda.
IF NOT t_mara[] IS INITIAL.
     SELECT matnr
            maktx
     FROM makt
     INTO TABLE t_makt
     FOR ALL ENTRIES IN t_mara
     WHERE matnr = t_mara-matnr.
   LOOP AT t_marc INTO wa_marc.
     READ TABLE t_mara INTO wa_mara WITH KEY matnr = t_marc-matnr.
     IF sy-subrc IS INITIAL.
        wa_marc-meins = wa_mara-meins.
        MODIFY t_marc.
        APPEND wa_marc TO t_output.
      ENDIF.
      READ TABLE t_makt INTO wa_makt WITH KEY matnr = t_marc-matnr.
      IF sy-subrc IS INITIAL.
        wa_marc-maktx = wa_makt-maktx.
        MODIFY t_marc.
        APPEND wa_marc TO t_output.
      ENDIF.
    ENDLOOP.

hi hema,
Dont use three select stements for this scenario.
Just use innerjoin and join all the three tables.
Three tables should contain MATNR (material number).
By using that retrieve data from 3 tables by using a single select statement.
Eg:
SELECT DISTINCT a~matnr    "MATERIAL NUMBER
         a~ersda    "CREATED ON
         a~mtart    "MATERIAL TYPE
         a~meins    "BASE UNIT OF MEASURE
         a~bstme    "ORDER UNIT
         b~maktx    "MATERIAL DESCRIPTION
         c~bwkey    "VALUATION AREA
         c~lbkum    "TOTAL VALUED STOCK
         c~salk3    "VALUE OF TOTAL VALUED STOCK
         c~stprs    "STANDARD PRICE
         c~peinh    "PRICE UNIT
         c~bklas    "VALUATION CLASS
         INTO TABLE it_matdetails
         FROM mara AS a INNER JOIN makt AS b ON a~matnr = b~matnr
                        INNER JOIN mbew AS c ON a~matnr = c~matnr
                        INNER JOIN marc AS d ON a~matnr = d~matnr
                        INNER JOIN mard AS e ON a~matnr = e~matnr
         WHERE b~spras = sy-langu AND a~matnr IN matnr AND d~werks IN werks AND e~lgort IN lgort.

Retrieve data from nested tables

Hi All,
I have big trouble to retrieve data from nested tables..
From java code developer are passing struct data type to Oracle procedure.. So equal data type in oracle has been created as created as object
CREATE OR REPLACE TYPE TXNDATA AS OBJECT
TRAN_ID            NUMBER             ,
EVENT_ID                   NUMBER             ,
EVENT_CD                   VARCHAR2(10 BYTE))and create a procedure which has a IN parameter as TXNDATA
now i need to retrieve the column data's through SELECT clause such as
TYPE Proc_txn IS TABLE OF TXNJOURNALDATA;
EVENT_JOURNAL_SEQ Proc_txn;
select * from table(cast(EVENT_JOURNAL_SEQ));but above SQL will give all column data's but i need to retrieve only 2 column values such as
select EVENT_ID , EVENT_CD from table(cast(EVENT_JOURNAL_SEQ))how can i achieve the above result set?
Thanks & Regards
Sami.

use a table alias in your query

How can i get all the records from three tables(not common records)

Hi
I have four base tables at R/3-Side. And i need to extract them from R/3-Side.
And i dont have any standard extractor for these tables .
If i create a 'View' on top of these tables. Then it will give only commom records among the three tables.
But i want all the records from three base tables (not only common).
So how can i get the all records from three tables. please let me know
kumar

You can create separate 3 datasources for three tables and extract data to BW. There you can implement business login to build relation between this data.

Create a procedure which requires displaying information from two tables

What if we want to create a procedure which requires displaying information from two tables. In this situation,
I need to display all the details of an employee from an 'emp' table based on the deptno. and also their salary information which is
stored in "Salgrade" Table. Is the use of "And" the correct way of using it?
Do I need to declare all the attributes before begin or I can just access them directly? Thanks
Create Procedure findDept
( I_deptno IN number
) As
Begin
Select Ename, Job, MGR, Hiredate, Sal, Comm, Dept_no from emp and exp, grade , location from salgrade where dept_no
= I_Deptno;
Exception
When NO_Data_Found then
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
End findDept;

Hi,
Besides Qwerty's remark, you've also got a quoting error:
Change
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
{code}
into
{code}
dbms_output.put_line(' Department not found: '|| i_deptno);
{code}
Which leads to the question:
What do you want to do when a record is found?
Display it?

Hi, experts. I want retrieve data from 8 tables

Hi, experts. I want retrieve data from 8 tables.
On which table i have to write for all entries query.
Thanks in advance.

Hai Reddy,
Actually IF we Use Join's Actually The Performance Will Be Good For 4 tables.
So It Is Better To Create Two Joins With 4 Tables Each.
First Retrive The Data For First View.
Then Use For ALL Entries For First Table And Then Get Data For Second data.
Reward If Found usefull.

you should change to request.getParameter("itemType").
or just System.out.print the itemType to see it got the value.
Hope it helps.

How to retrieve information from iCloud (earlier than the 3 most recent backups) ?

I had to restore my iPod 4th generation to factory settings and I'm trying to get all the information back from iCloud backup. The thing is that I had waited about a week or two(instead of right away) to try to put the information back into the iPod. And when I restored it again(for the second time) it only had the choice of retrieving informaiton from the 3 most recent iCloud backups but those were too recent for the information I wanted to get back. Is there any way, ANY WAY AT ALL that I can get access to earlier iCloud backups? Like maybe all the iCloud backups that have happened so far?
I've done some research and it doesn't say there is a way but there doesn't seem to be a lot of people with this problem. :( Please if you know a way, let me know.

Welcome to the Apple Community.
Unfortunately, you cannot go back further than the three backups that you already have.
