Server Utilities :: How To Get Parent Table Column Reference
Sep 24, 2013
I have csv file which having parent and child related data.i need to load parent data in to parent table and get parent reference id and store in child table with child data. i am not able to find how to get parenet refernce id using control file. In my csv file i have 2 parent name rows. I need to create one A record in parent table and get that parent primary(P_ID) for 'A' record and put into child table for c_name test1 and test2 records.
My controll file
-------------------
LOAD DATA
INFILE 'mydata.data'
APPEND
INTO TABLE parent
when (1:1) = 'p'
fields terminated by ',' optionally enclosed by '"' trailing nullcols
[code].....
able to load parent data and generate P_ID, but i am not able to get P_ID for child records.
I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.
I need to copy one table which is having NCLOB column into our new DB(11g) from old DB (10g). As this table having huge records (1 crore) it is difficult to use direct insert statement (INSERT INTO ... SELECT * FROM @remotedb). I don't have DBA privilege to use loader.
I have written the code for sql loader, I have given termination of file is | , i have given five columns name in sequence...My Requirement is that i want to mapped 100th column from Csv file after 5th column how to do it.

We 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.
My requirement is to load the data from feed file into two tables based on the value of a column in feed file.
say column in feed file is "Activity_Value" . If the Activity_value is 10, the data from feed file should be loaded into Table A and If the Activity Value is 20 the data from feed file should be loaded into Table B.

The value 603 should have loaded into TRAN_TYPE field or column, instead it loaded into the next field or column LINE_COMP.
I want to insert calculated data while loading the data from sql loader.
eg let say column INTERNAL_TRANSACTION_ID,WAIT_TIME,MESSAGE_GUID,TRS_SIZE,RETURN_MESSAGE_GUID are null in input file then i want to populate column DEV_FLAG as 'U' ELSE 'D'
My control file looks like below but doesn't have DEV_FLAG.

I have the following table intra_trades with t_id as the primary key. There is a trigger on that table that gets the next sequence and inserts it into the t_id column for every insert. I need to load data into that table using SqlLoader as chunks of 3000 rows and return the t_id back the script that Sqlload the data so that it can use that t_id's for the next process in the script.
The problem is that the only unique key on that table is the t_id which has a sequence on it and it is the pk. There can be duplicate rows in that table to meet the business needs for the company. So it is hard to associate the rest of the data in a row with t_id. The only thing I can think of is return the t_ids in the order it inserted so if the script keeps the order of rows in the memory it can associate the tid with the rest of the intra_trades info.How can I make the sqlloader return an array of t_ids that inserted? I need to return the t_ids's in the order it inserted so that the script can associate the t_id with the rest of the rest of the data in a row.
Sl#Emp_noNameAddress 00101Tom1/B-XYZ street 00202Jon1/C-XYZ Street
Employee Datafile 001, 01, Tom, 1/B-XYZ street 002,02,Jon, 1/C-XYZ Street
Above is a sample data file. Now I would like to import the data into an Oracle table called employee using Oracle 9i SQL Loader utility. But the table has only 3 fields (Emp_no,Name & Address), so I would like to skip Sl# while loading data. I do not want to manually modify data file. How should I write .ctl file.
Sample .ctl file.
load data INFILE 'dataEmployee' BADFILE 'Employee.bad' DISCARDFILE 'Employee.dis' into table Employee fields terminated by ',' TRAILING NULLCOLS (Emp_no NULLIF Emp_no = BLANKS, Name NULLIF Name = BLANKS, Address NULLIF Address = BLANKS )
Table1:event_channel Table2:event_inst I have to update event_channel one column with 4 record(channel_type_id,values 1,2,3,4) with respect to one record of event_inst table column(event_instance_id). event_inst table column(event_instance_id) has respective 4 records in event_channel
I have two tables A and B. In table A there is a field which contains a string of 20 characters; this essentially holds 5 codes of 4 characters each.
Table B is a reference table. It holds the 4 character code and the description.
I am trying to run a select query to bring back the description of the code for the first 2 codes in table A but i am not sure how to bring back the descriptions! The below is what i am trying to achieve.
I have a table DW_ORDER_CHANNEL and I need to know what are the other objects accessing this table. As i need to alter this table so the dependent objects get invalid. how to get the dependent object on this table?
There are 2 tables : Table A and Table B.Table B has foreign key reference to Table A.There are 2 forms in the application based on table A (form 1) and table B (form 2).
Now when we open form 2, the functionality is such that it acquires a lock on table B for the selected record during the search criteria. Lock is acquired by using "select 1 from table_B where column = :column for update no wait".So when the form 2 is opened by any other user/session and same record is tried to be selected, then an exception is raised to the user that the current record is being edited by some other user and does not allow him to edit that record.
Now imagine if User has opened screen 2 (One record in Table B has been locked). With this lock existing, we open form 1, and click a button which performs a COMMIT_FORM. At this point the form hangs. On checking the locked objects, there is a lock on both table A and table B. When the Form 2 is closed, then the Form 1 which was hanging a while ago starts responding.
When the foreign key relationship is dropped and the above scenario is tried, there is no issue encountered. Form 1 works fine even if form 2 is open.We are not supposed to drop the Foreign key relationship as well.
I have a standard schema named ABC and 600 more schema's over there in my database.They all has same table name and column name as on standard schema. But in some tables number of columns varying. So I need to compare all schemas with my standard schemas column name. I create below script but it is generating output in infinite loop.
SET SERVEROUTPUT ON DECLARE V_COLS VARCHAR2(20);

I have one issue while loading the value through sql*loader the last column data is SG1 and when its loaded , it is length of this columns is showing 4 char. Unable to understand, how to find this extra space. Though used TRIM but does not work.
I successfully loaded a record into table with BFILE data type. However I don't understand how to verify if I did this correctly. I am also suspicious of the value FSSLPB//I. FSSLPB is the directory object name. When I delete the record from the table the BFILE column value defaults to (null) so it seems the table is initialized for accepting bfiles.
I am trying to:
1. Load an external LOB into a staging table using SQLLDR, then 2. Using PL/SQL insert the ext LOB into a BLOB column from the staging table to an end user table (or application table).
I am overwhelmed with reading docs and not getting the complete picture for different approaches to loading into Oracle.
I was cloning a schema user1 as user2 in the same database.
user1 had quota on 2 tablespaces user1_data and user1_index.
I created user with name as user2.
I created tablespace user2_data only and granted user2 unlimited quota on that tablespace only (did not grant him 'resource' role or unlimited tablespace privilege) Now exported user1 schema as follows
during import i encountered following errors for so many constraints
"ALTER TABLE "table2" ADD CONSTRAINT "constraint_name1" FOREIGN KEY ("CTR_ID") REFERENCES "table1" ("CTR_ID") ENABLE NOVALIDATE" IMP-00003: ORACLE error 2270 encountered ORA-02270: no matching unique or primary key for this column-list IMP-00017: following statement failed with ORACLE error 2270:
I found that the it happened as the primary key of table1 was not created for which error was logged in the log file
. . importing table "table1" 19441 rows imported IMP-00015: following statement failed because the object already exists: "ALTER TABLE "table1" ADD CONSTRAINT "T1_PK79" PRIMARY KEY ("CTR_" "ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 65536 F" "REELISTS 1 FREELIST GROUPS 1) TABLESPACE "USER1_INDEX" LOGGING ENABLE " . . importing table "table5" 0 rows imported
However, I checked that the T1_PK79 does not exist in the user2 schema though it exists in user1 schema Neither the index for priamry key (T1_PK79) existed in user2 schema not the table <table1> existed before this import Then what could be the reason that I am getting an error "IMP-00015: following statement failed because the object already exists"?
I assume tablespace for index would not be an issue here as other indexes got created properly in user2_index tablespace during this import.
I tried this twice, once with user2 schema and then with user3 schema as well (with different tablespace), but result is the same.
There were no users connected to the database during export and no background jobs were modiying any data in schema user1 while export.
CREATE TABLE test_A(member_id NUMBER(2) PRIMARY KEY, MEMBER_name VARCHAR2(20), MEMBER_parent NUMBER(2) DEFAULT NULL); INSERT ALL INTO test_A VALUES (1, 'mem1', NULL) INTO test_A VALUES (2, 'mem2', NULL) INTO test_A VALUES (3, 'mem3', NULL) INTO test_A VALUES (4, 'mem4', 1) INTO test_A VALUES (5, 'mem5', 1)

As the actual data is huge, I need to know the best (least expensive) way to select each parent and then all its direct child ordered by member_id the output should look like:
i need to find the parent and child from the table in this case the parent is Classics & Poetry and child is Literature & Anthologies..the way of getting only the parent and child record from this table.
I have a parent table and child table. I want a row to be deleted from the parent table which is referenced by a child row. Is there a way to achieve this. I dont have permission to re create the table or alter the table using delete cascade option. Is there a way to do it in sql.
