Similar Table Structure Having Similar Indexes?
Sep 24, 2010
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?

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,
GAR_DW.L_DIA o10475639,
[code]...

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 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

--this for txn details
CREATE TABLE txn_det(
txnid NUMBER PRIMARY KEY,
amount NUMBER,
status varchar2(50),
cust_id NUMBER);
----this for customer details
CREATE TABLE cust_det(
cust_id NUMBER PRIMARY KEY,
cust_name VARCHAR2(50),
cust_acc number(15));
--data to insert for customer table
INSERT INTO cust_det VALUES(101,'Miller','12345');
INSERT INTO cust_det VALUES(201,'Scott','45678');
----data to insert for txn table
INSERT INTO txn_det VALUES('tx0045',123.00,'success',101);
INSERT INTO txn_det VALUES('tx0046',4512.50,'success',101);
insert into txn_det values('tx0049',78.12,'success',101);
INSERT INTO txn_det VALUES('tx0055',123.12,'success',201);
Now THE problem IS cust_det TABLE's cust_id coulmn may contain duplicate.So I thought OF adding THE txn_id COLUMN TO THE cust_det table but I know that encourgaes redundancy.

create table my_rows
(
my_envvarchar2(100),
anumber(2),
bnumber(2)
)
/
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
insert into my_rows values ('A', 10, 20);
[code]....
The first row means that the value 10 represents 40% in the couple (10,20). Meaning if I have 100 rows with the couple (10,20), 40 rows will be marked with the value 10 and 60 will be marked with the value 20. To do this, I used to create a temporary table with the same structure as the my_rows table with a new column "the_value" and I used to update this new column wth a PL/SQL for loop. But I think it is doable in a signle SQL.

I am receiving two large export files from a vendor, so I have no control over the contents. I need to import these into our database. The two export files are very similar, except the one has slightly differenet columns in it. So, export file 1 may have a table:
COLUMN_A
COLUMN_B
COLUMN_C
The second file may have:
COLUMN_A
COLUMN_B
COLUMN_D
At the destination, I have a table that has:
COLUMN_A
COLUMN_B
COLUMN_C
COLUMN_D
Is there a parameter that would let me interchangably import either (or both) files into this destination table? This is my first attempt at data pump - but I know using import this has caused me issues. Not sure if the same limitations exist? Will the missing columns cause it to fail?

I have a requirement to be coded like this:
A function to return pl/sql table(cant use ref cursor) whose columns varies every time it runs i.e,
means
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000))
type pl_tab is table of pl_tab_type
func f return pl_tab
as
...
end;
note : pl_tab_type will vary for each run of function f
i.e.,for example, pl_tab_type can be changed to as follows:
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000),col3 varchar2(1000))

I am working on Pro*C and i have a requirement where i need to select all the rows from a table into a c - structure variable. Since i get to know the no of rows in the table which is getting selected only at run time, i need to create a pointer variable to the structure and i'll allocate the size to it based on the count of rows in the table using malloc or calloc.I tried allocating memory using calloc and it does not show any error. But when i when the exec select statement run it shows an error.
Statements i have used:
struct common *comp;
struct common_ind *comp_i;
comp = (struct common*) calloc(rowcount, sizeof(struct common));
comp_i = (struct common_ind*) calloc(rowcount, sizeof(struct common_ind));
exec sql at db1 select * into :comp indicator :comp_i from tab1;
Error i get :
Stop Error: -2112
Stop Error: -1012
Stop Error: -1012
