Dumping Relevant Data From Columns Of Different Tables - Report / Join
Nov 18, 2008As the title of this topic illustrates, i'm having trouble dumping relevant data from columns of different tables. I am using isql*plus. I have three tables appropriatly related. A 'course' table, 'student' and 'next_of_kin' tables. I have many students enrolled on various courses but only a hanfull of courses offer the module option 'Database Systems'. I have no 'module' table but i know the three course names which provide the module option. I intend on producing a report hich lists all students enrolled on the courses which provid the module option 'Database Systems'.
I have attempted the report but i keep getting a 'cartesian product' displaying all next_of_kin names instead of the appropriate. Also i am struggling to come up with the right WHERE statement to depict only the three courses which provide the module option 'Database Systems' as defined by 'courseNo' in both 'course' and 'student' tables.
Here is the most recent attempt:
--set echo off
--set pagesize 24
--set feedback off
--set linesize 78
col A format 99999999 heading 'Student No'

SQL & PL/SQL :: Compare 2 Tables Based On 2 Columns
Oct 19, 2010My tables looks like this:
Desc Table A (account)
Account1_id
Account2_id
name,
empid
Table B (Bill )
BillNo
Advertiserid
agencyid
total vvalue
I need to pick up total value from table B where the unique combination of advertiser-Agency id is the same as the given account1_id -Account2_id combination in table A for each employee id.
In other words my output should be like
Empid | Account_id (should be same as advertiserid)| Account2_id (same as agencyid) | sum(total_value) for this adv-agency combination.....
objective: Get the total value from table B for each unique account1-account2 combination (advertiser-agency in other words) .
I am not sure if I should use a correlated subquery or how to handle the situation....Right now I am just checking the two columns separately like this:
select.......from a,b
where b.advertiser_id = a.account1_id and b.agencyid = b.account2id
Is it correct to do so? I have a feeling that I am missing something if I join them separately like this.
PL/SQL :: How To Retrieve Information About Columns Of Tables
Nov 16, 2012I am trying to get information about the columns of tables in Oracle databases. In MySQL, show columns provides good deal of information.But in Oracle, we do not have such equivalent call."describe" shows only the primary key.
But it does not show whether any column has unique constraint or an index.
I created a column in a table with unique constraint (but not a primary key), but it was not listed with CONSTRAINT_TYPE = 'U' in dba_constraints view, but was listed with CONSTRAINT_TYPE = 'C' - Check constraint.

View 2 Replies View RelatedPL/SQL :: Merge / Update With Multiple Tables And Columns
Sep 6, 2013I am trying to update multiple columns from one table based on the results of another table So I have 3 tables as follows
HISTORYSUMM_SNAPADM_CHOICE
My SQL code is loosely SELECT SUM(H.HIS1),
SS.SNAP1,
AC.ADM1FROMHISTORY H,
SUMM_SNAP SS,ADM_CHOICE ACWHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2GROUP BY SS.SNAP1,
AC.ADM1
This works, and I am able to SUM the column as I need with the right numbers. I altered the SUMM_SNAP table and now I want this summarized column to be in the table I tried using UPDATE, but there is no FROM clause to let me do the table join/group by
UPDATE SUMM_SNAPSET SUMM_SNAP.SNAP3=SUM(H.HIS1)FROMHISTORY H,
SUMM_SNAP SS,ADM_CHOICE AC
WHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2
GROUP BY SS.SNAP1, AC.ADM1
The above is obviously wrong - but just trying to show whatI was thinking What would be the best method to get the numbers from the SUM into a table?

I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
[code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.
