PL/SQL :: Avoid Record Creation With Similar Names
Oct 17, 2013
am trying to add a validation in Oracle forms using Oracle DB.in a Oracle table consider there is a record named 'Netbook' then if I try to create another record with name 'Netbooks', then a Oracle warning message should be displayed stating similar name 'Netbook' is already available. same way, if NETBOOKS is already available in table and if user try to create another record NETBOOK then same warning message netbooks is already available should be shown.

I do have problem with a table which have same structure of other table with indexes created being the same. Both tables have partions & subpartitions. Let us consider two tables table1 & table2. The problem i face is the index for table1 not being used when its being joined with other respective tables in a query. Whereas for table2 its working perfectly and cost is also less. I have used the explain plan and compared and query timing also takes more time. what might be causing it?

is there any possibility or hint to avoid updating record if columns do not change? For example, I have UPDATE:
UPDATE MY_TABLE SET COLUMN_A = 'ABC' WHERE COLUMN_B = 12
if the value in COLUMN_A is 'ABC' I do not want to do this update. Of course I can add in WHERE 'AND COLUMN_A<>'ABC' but when I am updating a lot of columns it will be annoying

I have a table
TAB1 with data
no name
1 abc
2 abc
3 xyz
4 xyz
5 cvb
now I would like to create a form with name counts as
abc 2
xyz 2
cvb 1
I would like to create a datablock to display all the unique names, not sure where I should be writing the query to display unique names. I would like to create a textitem box to display the counts when the form is compiled, but not sure which trigger to use to write the query.

I have two tables with almost the same columns. Table A has 50 columns, Table B has 51 columns, which are defined exactly the same except one more column as LOAD_TIME.
Is there any easy way for me to move the data from Table A to B? the Extra column LOAD_TIME will be set as current system time. All I want is to avoid list all 50 column names. The following SQL has error ORA-00923 error.
INSERT INTO TB_B
SELECT *, sysdate from TB_A;

I have this sql (generated by discoverer plus), and work fine:
SELECT COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,
GAR_DW.L_DIA o10475639,
[code]...
We need change the table stock_por_sucursal for a view like this, with similar indexes each table
select * from stock_por_sucursal_old
union all
select * from stock_por_sucursal_new
and the result is not good:
SQL Statement from editor:
SELECT COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,
GAR_DW.L_DIA o10475639,
GAR_DW.V_STOCK_POR_SUCURSAL o10475761,
[code]...
finally add a HINT /*+ gather_plan_statistics push_pred(TABLE) */ and the result was not very good in this case, but improved the resolution of the view, the rest got worse
SQL Statement from editor:
SELECT /*+ gather_plan_statistics push_pred(o10475761) */ COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,

I have an question.
- Imagine I have an table with several ZIPCODE.
- Imagine I want to return from that table the existence of several zipcodes I need to get.
- Imagine that I need to return both zipcodes that exists and both zipcodes that not exist.
The solution I've found to do this, was using the Pivot method, like the sample below, if there is another way to return anything like that. Return the zipcodes that exist, and the zipcodes that does not exist also!
Table Creation:
CREATE TABLE "AAA_ADDRESSZIPCODES"
("ZIPCODE" NUMBER,
"NAME" VARCHAR2(50 BYTE),
"COD_PLACE" NUMBER
)
Data:
Insert into GSCIS.AAA_ADDRESSZIPCODES (ZIPCODE,NAME,COD_PLACE) values (1100,'Portugal',2);
Insert into GSCIS.AAA_ADDRESSZIPCODES (ZIPCODE,NAME,COD_PLACE) values (1150,'Portugal',2);
Insert into GSCIS.AAA_ADDRESSZIPCODES (ZIPCODE,NAME,COD_PLACE) values (1000,'Portugal',1);
Insert into GSCIS.AAA_ADDRESSZIPCODES (ZIPCODE,NAME,COD_PLACE) values (1200,'Spain',2);
Select using Pivot:
SELECT *
FROM (SELECT distinct zipcode FROM aaa_addresszipcodes group by zipcode )
PIVOT ( count(zipcode) FOR zipcode IN (1000,1100,1200, 1150, 2000) )

I am using: Oracle SQL Developer (3.0.04) Build MAin-04.34 Oracle Database 11g Enterprise Edition 11.2.0.1.0 - 64bit Production Sample dataTable
with t as (
select to_date('8-18-2013','mm-dd-yyyy') dt, '123_' ticket_origin, '123' ticket_destination,101 startid, 101 origin, 0 destination, 'origin' objecttype, 85 amount, 100 area from dual union all
select to_date('8-18-2013','mm-dd-yyyy'), '123', '123_',101, 0, 103, 'destination', 85, 100 from dual union all
select to_date('8-18-2013','mm-dd-yyyy'), '123', '123_',0, 0, 103, 'destination', 85, 100 from dual union all
select to_date('8-17-2013','mm-dd-yyyy'), '124._', '124.', 105, 105, 0, 'origin', 150, 200 from dual union all
select to_date('8-17-2013','mm-dd-yyyy'), '124._', '124.', 106, 105, 0, 'origin', 150, 200 from dual union all
[code]..........
Is there a way to check in that date grouping for matching ticket_origin and ticket_destination when there may be two or more rows difference between them that does not allow me to use Lead or Lag function. Is it also possible do so without using the amount column? I also would like to identify if they are in the same area when paired (this I believe works after getting table sorted like so below then use lead lag after having the order by done) I am trying to get something like this table with results as
select to_date('8-18-2013','mm-dd-yyyy') dt, '123_' ticket_origin, '123' ticket_destination,101 startid, 101 origin, 0 destination, 'origin' objecttype, 85 amount, 100 area from dual union all
select to_date('8-18-2013','mm-dd-yyyy'), '123', '123_',0, 0, 103, 'destination', 85, 100 from dual union all
select to_date('8-17-2013','mm-dd-yyyy'), '124._', '124.', 105, 105, 0, 'origin', 150, 200 from dual union all
select to_date('8-17-2013','mm-dd-yyyy'), '124.', '124._', 105, 0, 106, 'destination', 150, 300 from dual union all
select to_date('8-17-2013','mm-dd-yyyy'), '127_', '127', 108, 108, 0, 'origin', 50, 600 from dual union all

I have a query that performs the sum of a field and divides by the number of occurrences, got me a problem because if there are no occurrences would cause a divide by zero error in Query.
The solution I found might not have been the best, but at the time was possible.
I put a Case, when the sum of the number of occurrence is zero then return zero, otherwise performs the division of the sum of the values by the number of occurrences.
SELECT CLIENT_ID,
TO_NUMBER(TO_CHAR(DTPROC, ''YYYYMM'')),
DTPROC, EXCHANG_VAL,
[Code]....
Now this query is very slow, because have CASE,SUM and GROUP BY, so I need to optimize it.
do this validation (if the divisor is zero) more performance?

I have created a procedure which sends mail to the users by using the smtp operation. I am collecting the email id of the users and then concatenating the same using the loop.
Everything is working fine, but if some person is coming multiple times in the loop, then his/her name is shown multiple times in the CC/BCC part (Although mail is sent once), it should be restricted to one time.
what i am doing is:
I have declared id_collector and it is concetenating the email as per the condition loop
........ some code here....
id_collector:=id_collector||email_id||';';
end loop;
Now, I want to check before concatenating that email already exists or not.
Example:
suppose value of id_collector= 'abc@gmail.com;pqr@gmail.com;rst@gmail.com;xyz@gmail.com;'
and again if email id comes - 'abc@gmail.com', then it should get rejected.
I think it can be done using reg_exp but I have messed up with that.
