I Have to write a procedure which takes XML data and inserts into some tables.
If the XML format is fixed then i can use extract function for parsing and can insert into the tables.
But the problem is there is not fixed format for the xml.
Are there any built in packages which takes the xml data for parsing..
We have been recommended to store data in CLOD data type.
Sample data: 1:2:2000000:20000:4455:000099:444:099999:....etc it will grow to a large number.
We want to create a Unique index, for functional reason. Is it advised to create a unique index on a CLOB datatype?
My requirement is to get primary key column name and there values of a table and store in a stage table
create table easy(id integer, event_rowid integer,txn_rowid integer,txn_name varchar2(200));
begin
for i in 1..5 loop
insert into easy values(i,'777'||i,i||89,'Ris'||i||i);
[code]...
I was able to fetch primary keys and there values for a table and store them in stage table but only 1 record , I am stuck when there are more than 1 record Here is what i tried
SQL> SET serveroutput ON
SQL> DECLARE
2 V_prim_key VARCHAR2(2000);
3 l_tab DBMS_UTILITY.uncl_array;
[code]...
If you look at the above code in the execute immediate where condition i have used id=1, which is 1 records only but if i change id <3 then there will be 2 records and i will get below error ORA-01422: exact fetch returns more than requested number of rows
Other problem if there are 3 primary keys as in above case i am fetching there values 1 by 1 , is there any way if i can fetch those values once in for all data to be stored in stage table in below format
TAB_NAME V_PEIM_KEY V_PRIM_DATA DT
------- --------- ------- ------
EASY TXN_NAME,EVENT_ROWID,ID Ris11,7771,1 10-Feb-13

I have a PL/SQL procedure which gathers data from multiple places as well as calculates some data. I want to store all this in a materialized view.
So, I created an object type (I've shortened the definitions):
CREATE OR REPLACE TYPE mf_record_type AS OBJECT
(identifier VARCHAR2(6),
name VARCHAR2(100));
Then created the table type of the object:
CREATE OR REPLACE TYPE mf_table_type IS TABLE OF mf_record_type;
Then in the stored procedure defined a variable of the table type:
v_mf_record mf_table_type := mf_table_type();
Then I loop and populate the record type:
v_mf_record.EXTEND(1);
v_mf_record(x) := mf_record_type(v_rec.identifier, v_mf_detail.name);
When all that is done I try and create the materialized view:
EXECUTE IMMEDIATE ('CREATE MATERIALIZED VIEW mf_snapshot_mv AS
SELECT * FROM TABLE (CAST (v_mf_record AS mf_table_type))');
ORA-00904: "V_MF_RECORD": invalid identifier
Am I doing something wrong here? Can't I create the materialized view based on something other than a physical table?
Since XML-files only contain character data, we could/should store it in a CLOB, rather than a BLOB.
But, One of my friend having a table where a column is defined as bloband came to know that XML data are being stored. I searched for some article with keyword 'How to insert large XML data in BLOB' But did not work.How to store the large xml content in a Blob and How to extract it?
I have string like 'PRASAD,ALLEN,STEWART,SMITH'.

how to tune qurey for coulumn wise data saved.because we have to join same table n number of times.for reference go through the following scnarios.
Suppose one table T1 is there and it has two column KEY and VALUE.if we are writing qurey for retriving desire result in row manner we have to join samae table no of times.
KEY Value
agreesWith true
id 1

bestOverallUnknownComments data is ok
Qurey:
select * from (
select t.agreesWith from t1 t
)a
[Code]...
In this manner we can join upto bestOverallUnknownComments .so which method we follow to reduce the execution time and performance should be good.

I'm using few cursors to update my data and store it back to the same table. But for some reason the cursor seems to be picking obsolete data.
cursor c1
is
select distinct roles
from table1
where flag = '1';
cursor c2
is
select distinct roles
from table1
where flag = '1';
begin
for i in c1
loop
here im updating the roles im picking to to a suffix and role.
update table1
set role = suffix_role
where 'some condition';
end loop;
commit; -- committing so changes are visible for my next cursor.
for j in c2
loop
here im deleting all the roles that are not part of my comparing table.
delete from table1
where role = 'something';
But in my debugging table i see that its deleting roles present as input for first cursor, whereas it should actually pick data with suffix_roles.
I have a Data entry form which is a multirecord block;
Question: for example that form has 10 to 25 fields or columns more than that all the data has been entered, but before committing or saving that form i need to cross check the the data with a select query, whether the data entered is correct or not but before committing, that data it should be posted into that table if i find that one data is entered wrongly then i will modify that and again cross check and save the transaction permanently into the database table?
I 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?

I have two tables
table1
col1.....................................col2
primary key................ foreign key refer to col2 in tab2
table2
col1 ........................................... col2
foreign key refer to col1 in tab1 ............ primary key
now my question is how to insert data in to the two tables
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_emptest1 EMP_TEST1%ROWTYPE;
v_emptest2 EMP_TEST1@ora%ROWTYPE;
v_suc_flg NUMBER := 0;
v_cnt1 NUMBER:=0;
[code].......
Is there any way i can select * from all the tables owned by particular schema at once.

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 have source table having 1000 records, i want insert first 100 rows in table1,second 200 rows in table2 and remaining row in table3.

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