Foreign Key Would Be Populated On Each Record / Other Would Be Null
Mar 22, 2013I have a central entity Address. I have other entities that could have many addresses (Organization, Person for eg). The relation between Organization and Address is one to many and the relation between Person and Address is also one to many.When I modelled it, I ended up having two foreign keys in Address (Organization ID and Person ID).The question that is being raised by the client is "As only one of the foreign key would be populated on each record, the other would be null". The client is not comfortable having nullable foreign keys as they won't be able to maintain integrity. One of the requirement is that No orphan records in Address. By modeling the way above, there are chances for having some orphanned records. I tried to explain that this would be controlled by the program to ensure that no orphan records would be there but their question is that what if someone goes directly and enters a record in Address table without any foreign key value (I dont know who would have an insert/update access on the tables other than the dba's).
I am trying to get some pros and cons on using the nullable foreign keys.

SQL & PL/SQL :: How To Check Record Exists Validation
Jan 18, 20111. Below TXN_LOG table Expected to have 0.5 to 1 million records & TXN_LOG_HIST table will have max 3 million records.
2. On daily basis system will move records from TXN_LOG to TXN_LOG_HIST.
3. The below mentioned check will be performed for each transaction, With out this check currently my process is doing 10tps. (transaction per second).
CREATE TABLE TXN_LOG

LOCATION VARCHAR2(3),
AC_NO VARCHAR2(20),
TXN_INIT_DATE DATE,
AMOUNT NUMBER(22,3),

The below validation we are currently using which is overhead for our transactions processing. Also the below mentioned check will be performed for each transaction, With out this check currently my process is doing 10tps. (transaction per second).
BEGIN

FROMTXN_LOG
WHERE AC_NO = p_acho

Is there any fastest method to check above record exists validation from the both the table?
SQL & PL/SQL :: How To Check Record Exist In Table
Feb 13, 2013Usually we check 1 row of data in table and compare if they exist, i want to compare different set of row all together to comapre and take the decisions
eg.
emp table_source
d_key emp_no invol
1 103499 1
1 99262 2
2 103499 1
3 103499 1
3 99262 2
target table
emp_no invol
103499 1
99262 2
103499 1
in the above example i have to check for d_key for set of row exist in target or not, so by above example d_key 1 and 3 has save value in 2 different rows so i want to check if the combination of rows
103499 1
99262 2
as a set appear in source then do nothing else insert so first time d_key 1 both records will insert but for d_key has same set in 2 rows will not be inseted. the number of row can be more than 2 also . so for the given key if we have 3 rows in source then i have to compare all the 3 same set of row in target exist of . in the target i don't have any extra column.

Server Utilities :: Field / Record Terminator - Trailing Null Col
Oct 7, 2010I need to load a file with fields separated by '|^|' and at end of each record has '||*||'.
So in my ctl file what do i mention ? fields terminated by '|^|' ? for the record termination wat should I say?
Should I still mention 'trailing null col' in my ctl file...?
Sample data file:
Name|^|Age|^|city||*||
john|^|33|^|||*||
james|^||^|nyc||*||
ken|^|44|^|
washington||*||
the fields are properly terminated with |^| and the records are terminated with ||*||. Is it true that a file with |^| as field terminator cannot be loaded with sqlldr?
SQL & PL/SQL :: Out Ref Cursor Based On Record Set

SQL & PL/SQL :: Using A Cursor Record In REGEXP_INSTR
Oct 18, 2012I've got a task to star out account numbers in a free text field. The account numbers can be in a few different formats and there are a number of tables. The formats could increase or change as could the tables. For that purpose I want to use a couple of tables; one to store the formats and one to store the tablenames. The tablenames work fine, but I'm having problem with the formats.
The table definition for the formats is:-
CREATE TABLE account_format (acc_id number(2),acc_format VARCHAR2 (200), acc_replace VARCHAR2 (200),acc_process varchar2(1))
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
and one insert would be
INSERT INTO account_format
VALUES (1,
'''[0-9]{5}[A-Z]{1}-[0-9]{5}''',
'''[0-9]{5}[A-Z]{1}-[0-9]{5}'',''****-****-****-****''',
'Y');
The idea is to bring back the format and use it in REGEXP_INSTR (or a similar REGEXP) to ascertain if the field contains the account number. The code I have been using looks a bit like this:-
CURSOR m_format_cur IS
SELECT acc.acc_format
FROM account_format acc;
m_format_rec m_format_cur%ROWTYPE;
IF REGEXP_INSTR (m_narrative, m_format_rec.acc_format) > 0 THEN
....
END IF;
I have tried several different ways to get this to work e.g. hardcoding the format and declaring a variable with the format, which both work. Whenever I try to use the value retrieved from the database field it never works. Why should a variable from a cursor not work?
PL/SQL :: Way To Make A Cursor Of Record ID
Nov 15, 2012I need to run a query that runs a stored procedure. The stored procedure takes a cursor of record ids as a parameter. I've been making the cursor like this, if there was a smarter way. I can't change the stored procedure, so this is the only thing I have control over.
CURSOR id_cur
IS
SELECT id
FROM table t
WHERE
t.id IN (
id1,
id2,
...
id500
);It just seems kind of strange to select only ids from records when the list of ids is given.
Forms :: How To Check For Unique Value In Text Item In Multi-record Block
Mar 13, 2013I have a multi-record block with several text items.

If it has already been entered then i want to display a message and null out the field.
I have tried using app_record.for_All_records from a when-validat-item trigger but this does not work as you get a 'FRM-40737 Illegal restricted procedure go_block in when-validate-item trigger ' error

SQL & PL/SQL :: Cursor For Loop Updates Only One Record?
Feb 17, 2012I have a table of 3 columns:
SQL> show user
USER is "ANDREY"
SQL>
SQL>
SQL>
SQL> --create the table:
[code]...
I insert rows into it:
SQL> --fill it with data:
SQL>
SQL> insert into a(key1 , key2) values (1 , 1);
1 row created.
SQL> insert into a(key1 , key2) values (1 , 5);
[code]...
i want to perform a logic by which:for every distinct value of key1 - values of key2 will be checked in all records holding that particular key1 value, and update the key3 field to 'inactive' where the key2 value for that particular key1 is the highest in number.
i've found out that i could do it by an SQL statement:
update a
set key3 = 'inactive'
where key2 = (
select max(key2)
from a a2 where a2.key1=a.key1
);
however I wanted to use the cursor to "load" the max key2 values FOR EACH distinct key1 value exists in the table,and do the same thing as the update statement above WITH A CURSOR,So tried and wrote the following:
SQL> create or replace procedure proc1
2 IS
3
4
5 var1 a.key1%type;
[code]...
unfortunately, it works only for one row, and i don't understand what's wrong, I executed, and checked what has changed:
SQL> exec proc1;
PL/SQL procedure successfully completed.
SQL> select * from a;
KEY1 KEY2 KEY3
---------- ---------- ----------
1 1 active
1 5 incative

PL/SQL :: Create Record Variable That Refers Dynamic Query Assigned To Ref Cursor?
Nov 11, 2012Just explaining what I am trying to achieve:
1) i have a hr.departments table that was loaded in hr schema on 1st oct 2012 with 4 columns(department_id, department_name, manager_id, location_id)
2) now I have a new schema by my name 'rahul' and I have loaded departments table but now an additional column has come into picture,ie created_date, this table got loaded on 1st-Nov-2012
3) Now going forward my columns could be dropped from the departments table (it can be a case), for example might be my departments table in my schema 'rahul' one day could comprise of only 3 columns(department_id,department_name,manager_id)
4) Now in the next step, I have managed to extract common column names(in a single line where columns are delimited using a comma) from both the tables(hr.departments and rahul.departments) which are (department_id, department_name, manager_id, location_id) using all_tab_cols table and I have written a function for it which i will be pasting below.
5) now going forward, using the above column names line with column names delimited using comma, I have used a ref cursor and assigned a query to it using the line of columns that I have extracted from the above point
6) Now I want to create a record variable which refers to my ref cursor, something like we do when we create a record variable by reffering to an explicit cursor defination that we give in the declaration block.
PS:
1) I have been out of touch with plsql for a long time so I have lost a lot of mmeory regarding plsql.
2) basically I need to compare data in hr.departments table with rahul.departments table for only columns that are common to both the tables, rest new or discarded columns information will go in one of the log tables that I have created(this is done already)
