I have 3 tables as below. I am looking to get data from these 3 table at a time using a pl/sql block but unable to do. Is there any way that I can get the data in a single query.
PS:All the columns are same in all the 3 tables
table1_COLLECTIONS_a
table1_COLLECTIONS_b
table1_COLLECTIONS_c
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;
it's possible to retrieve the names of tables that contain similar information in an oracle database.
View 7 Replies View RelatedI 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?

View 2 Replies View RelatedI have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?

- 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) )

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

I have two databases.
one is "ora" it is a 8i version
2nd is "orcl" it is a 11g version
"Oracle" is the my local database. i wrote following program for comparing the row by row data in both the tables.
Q)Is it BEST practice? If not let me know the best practice to compare data in tables?
Q) If am not using the order by clause its giving me wrong output even though both the data tables has same data. WHY?
DECLARE

v_emptest2 EMP_TEST1@ora%ROWTYPE;
v_suc_flg NUMBER := 0;
v_cnt1 NUMBER:=0;

What are some performance issues you might run into when having to query 3 or 4 tables at a time.
View 1 Replies View RelatedI have a requirement to get the data in "SQL" directly and should not use plsql/ can't redirect the output to a .sql file. I have a master table Main_tab which does have all "child table" names.
I want to build a query such that it will give all the data from child tables.
create table main_tab ( tab_name varchar(10));
insert into main_tab values ('one');
insert into main_tab values ('two');
insert into main_tab values ('three');
create table one ( a char);
insert into one values ('a')
create table two ( b char);
insert into two values ('b')
create table three ( c char);
insert into three values ('c');
Now I have got the query to combine all the table data using
select decode (rownum,1,'','union all ') || 'select * from ' || tab_name example from main_tab
but I am expecting the output to get as
a
b
c
which is the data from tables one,two and three respectively.
I don't want to save the above select data in to .sql and then execute it , instead I want to run it on "fly" in SQL itself. Is there such a possibility to do so?

I have to move data from old tables into new tables. I use a sqlplus script and execute multiple 'insert from select'. I thought the SQL statements are executed in sequence, one after the other. I run into this problem: Let's take this script for an example
insert into A (a,b,c,....
select a,b,c......
from X;
insert into B (a,b,....
select a,b,....
from A joined with Y;
commit;
After executing the script in our development DB
select count (*) from A
returns 200
When the script is executed in production, A table record count is 5
select count (*) from A joined with Y; (used in the second insert)
returns 200.
It seems that the two statements are executed at the same time and table A is not fully populated when the select in statement two is executed.I suspect this is due to parallel execution in production.
Will executing
ALTER SESSION DISABLE PARALLEL DML;
ALTER SESSION DISABLE PARALLEL QUERY ;

I'm having trouble to get the weekend records from 2 tables. table 1 has a start date and an End Date. Table 2 has END_INTV_TIME ( HOUR FORMAT AS 0100-1am,0200-2am.......1300-1pm,1400-2pm.....2400).
create table t (traffic_sample_id number,
site-id_nbr varchar2(12),
start_date varchar2(6),
end_date varchar2(6)

My requirement is to get the weekend days and i tried using the function
( TO_DATE (start_date,
'mmddrr'
)
+ TRUNC (rn / 24),
'Day'
)

But the problem is its going just after the table1 START_DATE and getting me the weekend day based on start date, but when i join the tables the problem is with the END_INTV_TIME, the recods start at 1000 (10am) (bin_data_id =1037804) so according to my logic the weekend records will be 48 records from the first record, but i want to take into consideration the END_INTV_TIME as well when its (0100 1am) then my weekend starts ie(1037843 bin_data_id) instead my weekend record is coming from 1037852 (1000 10am) ,
