The manual work around on populating child tables for testing purpose are taking long time and its very painful work. So I am trying for a tool that takes parent table name and child table name as input and produce insert statements for child table with foreign keys as output.
View 5 RepliesI have 1M Records coming from an External Data source as a Flat File (using ETL). Now I need only Yesterday's data only to load in my Database Table.
this can be done using Bulk Load and Filter.
write the CODE.
Second Part:-
Hint: if I need to update only those records been updated Say the Address1 field is updated. So this records need to update in my Master Customer Table.
If I have many fields in table and any records that are modified (coming to me from External Datasource as a Flat file) how to identify and update that record in my Master Customer Table?
i have a table with 15 coulums and containing millions of rows which is being updated everyday.Now i have created a similar report table with only the coulums i need to report on from the main table.what plsql script or if there is any better alternative do i need to write to copy the data from the coulums i need from the main table to the new report table. the new report table will be be updated every 01:00am with the data coming from the main table and the update is automated.
View 3 Replies View RelatedWe have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.
I have got two tables emp_dtl and iou_tab. i have already made entries i.e booking no, emp_cd, emp_name etc in emp_dtl snc its my master table. I want to retrieve the booking nos through lov in iou_tab which are generated in emp_dtl and corresponding info of emp_cd and emp_name should come in the respected fields in iou_tab.

View 9 Replies View RelatedI've a table TXN1 transaction and has FKs to 3 different tables Account, customer, country and currency. ALL FKs are indexed (bitmap). I am updating TXN1 of amount column about 10,000 rows. (SID 1) As expected, it has taken lock type 3 SX on TXN1. But it has taken on lock type 4 (share) on Account, customer and country. Committing every 10k rows.
At the same time sid 2 is inserting into another TXN2 table which has FK to the same dimensions account, customer and currency. Only FK on ac_id is bitmap indexed. The inserts have taken SX lock(type 3) on tXN2 table (expected). But it is trying to take SX type 3 lock on account, customer, currency tables. typ3 lock taken on CCY but waiting on CST. But It is blocked by sid 1. It has resulted into Enque-TM contention and resulted into anywhere 60-300 secs wait time..
I understand update/delete in parent table results into locking of SX of child tables and need the FKs to be indexed to avoid etc.
1. Why is SID1 taking shared lock on the parent tables Account,customer,country and currency tables? The update statement is not updating any of those FK columns nor referring them in where clause(if it matters!). Is it to ensure that the parent rows are not deleted?
2. Why is SID2 taking SX lock on the dimension tables? Why is it not taking RS lock type 2 on parent rows? Why is SID1 taking shared lock type 4, but not 2?
I want to delete records from parent table which are less than 2 years. Before deleting records from parent table we have to delete records from child table. How can we delete those records. I don't want to use ON DELETE CASCADE.
MASS_MASTER --parent table.
MASS_CHILD --child table.
The below query is used to delete records from parent table.
DELETE FROM mass_master WHERE last_date<=ADD_MONTHS(sysdate,-24);
The child table MASS_CHILD is not having last_date column. provide me the query to delete same records from child table.

I am using the Oracle 10g and I have question related to "for Update" clause.We have the data warehouse db, so no foreign key constraint between parent and child.We process the data files every hour, the condition is If we find the row in parent table then we go and look into child tables and perform insertion (if no corresponding record is present) or updation (if one corresponding record is present) in the child table.
The problem is If I run the two process simultaneously for the same kind of data, and if no record is present in the child table then it create the duplicate in child table.My question is if I use FOR Update clause while selecting the data in parent table will it lock the child table for any insertion or updation?
Ex- We have employee table for employee 1
In my data files I have the row for employee 1, so when I run the select query on employee table I found 1 row.The I look the child table "Salary" as there is no record for emp_id =1 in this table I insert the record for this
Emp_id Salary
1 500
The problem is if both the process run at same time then I get duplicate rows in child table
Emp_id Salary
1 500
1 500
we do not want the duplicate row insertion. Can I lock the child table during first process run
I found nothing in SQL (all in PL/SQL).I have a table:
create table Parent (pk_id number primary key); --which is filled using sequence seq_Parent.
And I have a child table:
create table Child (rRef number, fk_parent number primary key (rRef, fk_parent);
that I need to insert into Child using seq_parent but I want to insert the same sequence for each group of rRef. I dont know how to do that using SQL not PL/SQL.

I have loaded into an Oracle table defined as XMLTYPE. I'm okay with PL-SQL and stored procedures, where I will ultimately do this processing once I get a handle on XML DB querying from an XMLTYPE table.
Based on reading the oracle documentation about XML DB, and more importantly, reading dozens of posts to this forum,I have been successful in loading the XML files into a SQL XMLTYPE table and doing simple queries against that table to retrieve some of its data so that I can then insert that data into other target oracle relational tables.
how to select parent/child data from XMLTYPE tables. I am able to follow the forum examples and can replicate the methods shown on the many example XML contents shown on this forum, but not against the XML that I have to process. I am wondering if my struggle is caused by my lack of knowledge, or by ill-formed XML content supplied to me by the educational vendor.The XML content has structured the XML content nodes in such a way that I do not seem to be able to apply the parent/child sql methods.I have been able to use for other XML examples I have tested against.
My XML file shown below represents High School Transcript data, for which I need to be able to parse out into my own oracle relational tables for that student, his personal info, and his course info, etc. i.e., for our example, which courses he has taken for which High School grade levels. The vendor-supplied XML seems to put the Courses and the High School grade level in "parallel nodes," instead of parent/child nodes, so I am struggling to be able to use SQL to differentiate which course the student took in NinthGrade versus TenthGrade.
-- WHat I would like to determine from a select statement:
LASTNAME GradeLevel COURSETITLE
=============================
Smith NinthGrade PHYS ED 101
Smith TenthGrade CALCULUS 201
Smith TenthGrade ZOOLOGY 202
(The data has been simpliied and masked, but is true to the content and is queryable).

I'm not sure if this is so much a SQL Loader problem as it is a database understanding problem, but here it is. I am having trouble loading data into a table (using SQL Loader) due to the fact that I am trying to load data row by row, into corresponding columns.
TestFile.csv
testvalue1, 123445
testvalue2, test
testvalue3, 455321
testvalue4, 65742
testvalue5, 5719
So, using the above data, I am trying to load the value for 'testvalue1' into a column defined as 'testvalue1'; the value for 'testvalue2' into a column defined as 'testvalue2' and so on. From my understanding, SQL loader loads by column not by row, so I am not even sure if this is possible.
