Fetching Data From Table In A Loop From Range Of Row?
Mar 23, 2012
I have dcs_sku table .The record count is 50 thousand in that table.My requirement is to fech every row,create an xml out of it and post the data to some third party.As the count is very huge,I can't select the entire record and do the operation at a time.way which I will run the sql query in a loop,which will fetch 1st from rown 1 to row 1000,next 1001 to 2000,2000 no 'n' row...
I tried the below query:
select * from dcs_sku where rownum between 1 and 200...This gave me the 1st 200 rows and worked fine.
but the moment I changed the query to :
select * from dcs_sku where rownum between 201 and 300:::No result was coming up.
here i have a table called cn_wghmtdt_trn and some table columns are shift_date(date),net_wt(nothing but crushing weight or cane wt),crop_type_code(rotoon or plant),shift_code(its like 1/2/3 but its default 1)
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.
User complaints fetching data from table A is timing-out ( as per application standards). I decided to collect latest statistics(dbms_stats) on index used by query which is running for more than 12 hours.not.It is partition table and got close to 10 millions records.
1) I checked dba_waiters - no rows 2) I checked v$locked_object/v$locks - no rows 3) I'm unable to run explain-plan for any criteria on that table 4) I'm unable to open table data-tab in Toad/ Sql developer. 5) I'm unable to query a single partition; no error but it keeps on running.
i need to do a loop on a table and export the data in Excel format (so i need a procedure to do it).
write a java class that build this Excel.. oracle procedure loop around the data and every step my Java class write on Excel file.
So, for this i should initialize my java class for example
public class ExcelExporter{ private String fileName; public ExcelExporter(String fileName){ this.fileName = fileName; } }
So, for this issuse i should call the ExcelExporter costructor from my PL/SQL so i can create an object of it and next i use this to populate my Excel.
How its possible to create Java object from PLSQL ? I've seen on the net all procedure call only Java static methods...
As per Article mentioned in Oracle Base,I have converted non-partitioned table (1 million data) into range-partition table,but,I don't see performance improvement in explain .
I have two different database servers where I need to migrate table data from one schema to another schema in batch wise for eg say 100 rows. I used BULK COLLECT with LIMIT. But to access BLOB data from table I have facing errors. What could be other approache to do the same.
here pc_work is a table containing BLOB data in sourse schema. I am fetch data from this table to table t1_test_work using dblink but not working
[ declare type array is table of test_work%ROWTYPE; L_DATA array; cursor C is select * from pc_work@prpctrg; begin open C; LOOP
I have a detailed block with a user ID column. The user name is not available in the block. Therefore, I have created a non-database column to retrieve the user name into it.
Here is the code I've used.
PROCEDURE get_details IS
iLoop number := 1;
CURSOR c is
SELECT FULL_NAME FROM GRP_EMPLOYEE WHERE EMPLOYEE_NUMBER = :USER_ID;
This query that I pasted is working correctly.Let's say a case has 4 owners, it finds me the first owner and show me its address.
However, I want to execute this query for all owners so it should jump the previous owner it found. Lets say for that example that the loop ends at 4. How may I fix this problem so that the loop do not return always the first owner but it keeps getting 1,2,3,4...also I should increase the sequence value for each situation
I have a table where multiple combination of records are store and i want to display data in range format as below, there is any way to group data as below.
I have in my database table 2 important date columns: StartDate (Not null) and EndDate(Allowed Null).I want to ensure that all records in the table would always create perfect contiues date ranges with no holes inside.Wor example there may not be records [1-may..1-may, 3-may-...] because there would be a hole [2-may...2-may]. Holes are not allowed.
And overlapping is not allowed, for example [1-may..1-may, 1-may-2may, 3-may-...] is not allowed because overlapping occures on day 1-may. Overlapping and holes are not allowed. But it is allowed that table has no records at all. But all DML manipulations with existing records must ensure that overlapping and holes won't occur.How to write such check? How to ensure that data ranges would stay continous with no holes and no overlaps?
Need to create Sproc(loop) to insert data..We have 2 table:
- BE Table Name Null Type ---------------------- -------- -------------- BID NOT NULL NUMBER(10) BUSINESSENTITYTYPEID NOT NULL NUMBER(10) PARENTID NUMBER(10) VERSION NOT NULL NUMBER(10) FULLNAME VARCHAR2(255) PHONE VARCHAR2(255) FAX VARCHAR2(255) [code]....
Whenever the BE table is read it gives more than 80K records from cust_id=1 and so on and becomes a bit slow ..
Now, when we copy the records from BE to CUSTPAYMETHOD (assume 30k). Next time when we read the table it should show us the customerid from 3001based on New Customer's(user created) Customerid.
CUSTID column is logically linked with BID column (FK not enforced) We don't have to pass parameter as we know the cust_id=1,flag for suspended='Y' and Eff_date between date1 and date2..We have accept from/to Period.Probably a loop to insert...This particular SP will run in all env and the id is going to be different how we are going to handle this...
We want to have a procedure. This is to purge BE table.
1) Insert a new parameter CUST_PMNT_MTHD_RETENTION_PERIOD into system_parameter table(which is only a parameter table) -- this can be done outside of Proc.
2)Create a new Customer(user id) through the Customer application and then find out the custID for the new customer -- this can be done outside of Proc.
SP should be for:
- Store Proc will Update the CustID in the CustPayMethod table to the new customer ID (that was created) when the EFFECTIVESTARTDATE older than CUST_PMNT_MTHD_RETENTION_PERIOD(from system_parameter table) days and suspended=’Y’.
- Copy records with custid=1(anonymous user) and startdata older than retention_period and suspended='Y' to Table CUSTPAYMETHOD
Eventually,delete the record from BE table.BusinessEntity(parent) table is information about customer and customerpaymentmethod(child) table is about payment mode(how payment is made by customer).
Assume If BID=1 then we can find Cust_id=1(which can have many records as the payment mode may change because the customer pay by different mode(credit,debit etc).We have to use loop and commit every 200 or 500 records.
FIrst we have to update the table with new cust_id and then insert...
I want to update column in table 1 based on a substraction of two column, one from the same table and the other from different table. Then update the result of substraction in table 1. Number of rows in two tables are different.
--for r in (( select (table2.y - table1.y as x from table1, table2 where table1.x = c and table2,.x = m)) declare i number := 1; c number ; m number;
a project I'm working on. I normally work in SQL Server, so I'm a little stuck on this one.
I have a temp table (tmp_stack) with four columns:
Floor [varchar] Unit [varchar] Block [number] BlockStart [number] BlockEnd [number]
BlockStart and BlockEnd are currently NULL. What I need to do is loop through the table for each Floor and update BlockStart and BlockEnd for each Unit depending on how many blocks they use and how many have been used by prior units on that floor.
For example:
There are three units on Floor #1: 1A, 1B, and 1C. 1A = 5 blocks 1B = 3 blocks 1C = 2 blocks
For 1A, BlockStart should = 1 and BlockEnd should = 5 For 1B, BlockStart should = 6 and BlockEnd should = 8 For 1C, BlockStart should = 9 and BlockEnd should = 10
And everything should reset back to the beginning on successive floors.
In T-SQL, I would use a cursor, and I assume I need to do the same kind of thing in Oracle, but I can't figure out the syntax.
i create form on which 3 window, 3 Canvas, 3 blocks are there.
1)first block contain 3 items from_date and to_date(nondatabase)and find button
2)second block contains 3 items segment1, quantity and payment_terms
when i enter 2 dates and click on find button 2nd window open. segment1 and quantity between this 2 dates comes from base table like
select segment1,quantity from po_lines_all pll, mtl_system_items mts where pll.ITEM_ID=mts.INVENTORY_ITEM_ID and creation_date between :FROM_DATE and :TO_DATE
and payment_terms should enter manually
3)2nd block contains summary button when i click on it, it save segment1, quantity, payment_terms and open new window which contain segment1 ,qty, payment_terms and when i click on summary button data comes from custom table which group clause means
suppose
item qty terms a 2 2days a 3 2days b 3 3days
then on third form i shows like this a 5 2days b 3 3days
i done all this things but problem is that
suppose once data between 21-aug-2010 and 24-aug-2010 comes on second form , i enter payment_terms and save it. sumaary form also run properly but if another user enter date between 22-aug-2010 and 30-aug-2010 then it will shows data between 21-aug-2010 to 24-aug-2010 from custom table i.e with payment terms as earlier it save and from 25-aug-2010 to 30-aug-2010 it shows data from base table
like
item qty terms date a 2 2days 21aug a 3 2days 22aug b 3 3days 24aug b 4 NULL(ENTER MANUALLY) 26aug c 5 NULL 27aug
formatting the data.I want to group the below table data based on the Grade column for a header_data with start_time and end_time displayed in range. I was trying with group by, partitions etc but no luck. I use version 10gr2.
partition 1 = < 2011 partition2 = <2012 partition 3 = any other value not staisfying partition 1 and partition 2
i would like to know how to create a partition 3 without specifying the range so that the data which are not coming under the range of other partitions (Partition 1 & 2) will automatically goes to this partition 3.
Also in the above case if i insert data of year 2009 then where will it go , to partition 1 (or) 2 since both of them matches the condition (<2011 and <2012) (or) do i need to use between clause while creating partitions?
