SQL & PL/SQL :: Display Tens Of Millions Of Data In Oracle 11g
Mar 12, 2013
i have a problem to view tens of millions of data in oracle 11g i have table Book_Issue that have tens of millions of data but when i execute query to see all the data select * from Book_Issue
it only view 5.000 data
what query should i execute to view million data in oracle 11g
I am trying to delete the one month data from the table , which contains the end customer sales data.The total data count in the table is 30 crores. And the data of one month is nearly 10 Crores.I am using oracle 10g , The date field to be used in the condition of delete is indexed.
I have a table which has plenty of rows. In production, I would estimate it to be from 30 millions to 300 millions. I need to update on column (flag) in all the rows (created before certain date).Now saying just:
UPDATE MyTable SET flag = 3 WHERE created < to_date('2010-10-08 23:59:59', 'YY-MM-DD HH24:MI:SS'); COMMIT;
Does not seem like a good idea - the commit-buffer would become too big.I will write a PL/SQL script for this. The question is, whether I should:
a) Update each row separately, and commit after every 10000 rows. ( WHERE RowId = [rowId] ) b) Update 10000 rows with set of dates ( WHERE rowId > [some_row_id] AND RowId < [some_row_id_2]
In the latter example the some_row_ids would naturally be fetched. The rowIds come from sequence. So which one would be more effective?I am not too familiar with PL/SQL or Oracle for that matter.
There is a table in Database with millions of records and a query --- Select rowid, ANI, DNIS, message from tbl_sms_talkies where rownum<=:"SYS_B_0" ---- using the high CPU and also this query having high number of executions.
which is the fast way of inserting 60 millions of records from a view to a table.
method 1:
create table t_temp_table as select * from v_dump_data;
method 2:
through bulk collect
---Bulk_Collect With FORALL---------- DECLARE TYPE srvc_tab IS TABLE OF t_temp_table%ROWTYPE; l_srvc_tab srvc_tab := srvc_tab(); l_start_time NUMBER; l_end_time NUMBER; l_error_count NUMBER;
Consider EMPLOYEES table and If an employee 'A' joined in Jan month then he should come under JAN, if employee B and C joined in MARCH month than both has to come under MAR and so on..
OUTPUT: JAN FEB MAR APR MAY JUNE JULY AUG SEP OCT NOV DEC A B D E C

Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.

I am stuck somewhere in my project, situation is that we are trying to display data gathered from 3 different tables, we used cursors for this, here is the cursor declaration.
DECLARE procedure DocInfoCur(myWhere IN varchar2) IS
init_dept_id number; init_dept_name varchar2(40);
rcvg_dept_id number; rcvg_dept_name varchar2(40);
CURSORCUR_DOCINFO IS SELECT DISTINCT I.CTN, I.DIARYNUMBER, I.INITIATINGDATE, T.TYPENAME, I.INITIATINGDEPT, I.DOCUMENTSUBJECT, I.DESTINATIONDEPT FROM DOCUMENTINFO I, DOCUMENTTYPE T, DEPARTMENT D
[code]...
This displays all the records out there.
Now, I have a search form where I need to filter the same data with different parameters, I have compiled the entered data in one string, now i need to join that string at the end of where clause of my cursor, how can I do that, i have tried concatenating both but received compile error, is there a way out in the current scenario???
