Use Of Query Clause For Nested Tables During Export
Aug 30, 2010
I have a query regarding nested tables while exporting. Are we not allowed to use Query clause during the export of nested table?
I am getting the error:
"EXP-00053: unable to execute QUERY on table NT_LP_COREBAL_MAINT because the table has inner nested tables
Export terminated successfully with warnings."
The exp command we are using is:
exp XXXX/XXXX@XXXX file=test1.dmp log=test1.log tables=nt_lp_corebal_maint query='where domain_id=10110307'.
I'm trying to use SYSTDATE in a WHERE clause of nested SELECTS..I want to select a range of info from two days back from today until today (or time it is being run). But when I run this, it says I have a missing expression...
SELECT XXXX FROM XXXX WHERE DATE BETWEEN TO_DATE(SELECT TO_CHAR(SYSDATE, 'YYYYMMDD') -2) AND TO_DATE(SELECT TO_CHAR(SYSDATE, 'YYYYMMDD HH24:MI:SS'))
Using Connect By on a query which has a nested from clause(The from clause fetches around 100k records) gives incorrect results but if the same nested queries are used to build a table and the Connect By is used on the table then the output is correct.
I put the nested queries in a 'WITH' clause and got the correct output also.
I am not sure how to give the code here as you would need dump to make them work. I am giving the a sample
--Non Working Code
SELECT con_item, prod_item, compsite, bcsite, ibrsite, res FROM (SELECT con_item, prod_item, compsite, bcsite, ibrsite, res FROM (SELECT bd.item AS con_item, bd.fromid AS compsite, bd.toid AS bcsite, bd.toid AS ibrsite,
Tables same column names but diffrenet index structures and traget one to be partitioned hence only want to import the content Each table on source datbaase hascolumn seq number and only want to extract the last few months of data.
TABLES:table1,table2... DUMPFILE=dump_dir CONTENT=data_only QUERY= table1:"WHERE seq_num >100 "want to use expdp but not sure about how to ensure all tables have the WHERE seq_num >100 condition, if leave table1: out and just have QUERY= "WHERE seq_num >100 " will this condition be applied to all tables which is what we want.
I'm assuming also can use impdp CONTENT=data_only?
I have some problem when i try to export data from a table which contains a nested table, using toad.
When toad generate the file, in the column corresponding to the nested table, toad just write a (DATASET) instead of the data contained in the nested table
Here is an example: INSERT INTO SSD_REV_S ( REV_ID, REV_TAB, REV_TS, REV_USER, REV_LOG ) VALUES ( TO_Date( '07/30/2007 12:00:00 AM', 'MM/DD/YYYY HH:MI:SS AM'), (DATASET), TO_TIMESTAMP('4/3/2009 11:20:51.000000 AM','fmMMfm/fmDDfm/YYYY fmHH12fm:MI:SS.FF AM'), 'operator', 'Add EVENT');
REV_TAB is my nested table
way to export data from a table which contain a nested table, as a list of insert statement, so i can move the data to a different database schema? I can also use different client tool.
There's a table T with a nested table within it on the master database. I need to mantain a materialized view of the table T on a remote database.
I get this error: QUOTE ORA-22804: remote operations not permitted on object tables or user-defined type columnsIs there any recommended workaround of this problem? The remote data must have the same structure as the master one.
The data should be refreshed every day, the data changes moderately, there are more or less 500 records.
In the example below I believe I have created a Nested Table of PL/SQL type and have tried various references to get the SET operation to work, line containing MEMBER OF. Taking the example below from the oracle documentation I have two questions.
1) As I understand it I should be able to use SET operations on Nested tables of PL/SQL types, (I am not using the CREATE OR REPLACE DDL statement prior to the DECLARE block.). Is this correct? 2) I am assuming that I have to reference the record, can I reference by its type / row instance or can I only retrieve the record like a Cursor Fetch solution, (which would defeat the purpose.).
SF at oracle.com/technetwork/issue-archive/o53plsql-083350.html states that you can compare two database tables (of the same structure) by defining a nested table type (using %ROWTYPE) and two NT variables of that type, and loading the contents of each table into its respective NT variable, before comparing them using the = operator. Having read the Oracle documentation which states that you can only compare NTs for equality if they don't contain record types, I was surprised to read this, but figured I would try it because I must be misunderstanding SF, but it didn't work.
SCOTT@ORCL> create table empcopy3 as select * from emp;
Table created.
declare type emp_ntt is table of emp%rowtype; emp_nt1 emp_ntt;
[Code]....
But SF goes on to say he timed the execution of his NT equality method, comparing it with a SQL-only equivalent, and so I must be missing something. My understanding is that using %ROWTYPE declares a record type.
How can I search in Nested Tables ex: (pr_travel_date_range,pr_bo_arr) using the SQL below and insert the result into a new Nested Table: ex:g_splited_range_arr.
Here are the DDL and DML SQLs;*Don't worry about the NUMBER( 8 )*
CREATE OR REPLACE TYPE DATE_RANGE IS OBJECT ( start_date NUMBER( 8 ), end_date NUMBER( 8 ) ); CREATE OR REPLACE TYPE DATE_RANGE_ARR IS TABLE OF DATE_RANGE; DECLARE g_splited_range_arr DATE_RANGE_ARR := DATE_RANGE_ARR( );
[code]...
Or can I create a VIEW with parameters of Nested Tables in it so I can simply call
SELECT * BULK COLLECT INTO g_splited_range_arr FROM view_split_date(g_travel_range,g_bo_arr);
CREATE OR REPLACE TYPE CourseList AS TABLE OF VARCHAR2(64); CREATE TABLE department ( courses CourseList) NESTED TABLE courses STORE AS courses_tab; INSERT INTO department (courses)VALUES (CourseList('1','2','3'));
[code]....
The query returns the correct data, CourseList that are not subset of any other CourseList of the table.
I am trying to convert this not exists in a left outer join query to check if the performance is better, but I don't know how to do it.
I was making some variations of this code :
select d1.courses c_1, d2.courses c_2 from department d1,department d2 where d1.courses<>d2.courses(+);
I am using expdp command to export the table by specifying Query parameter. But i am unable to export the table based on the condition.

The data table is shown on the picture.i75.photobucket. com /albums/i297/lovebipbo/SIT103.jpg.. I can learn and do some similar task myself
I need to incorporate a count of the number of units from TableG that have a certain status. I tried the following but when I tried to run it, I get an error saying that it's not a Group By expression -the red part is highlighted in TOAD.
select B.desc "Location", F.desc "Source", A.amt "Amount", sum(G.G_CNT) "No. Units", (select count(*) from TableG G2 where G2.D_ID = D.ID and G2.status = 10 group by G2.D_ID)"Count", c.desc "Status" [code]....
Any thoughts how I can incorporate a query in my select of attributes?how to Group By something.
In the below Table Structure, TB_Vehicles is the Master table and TB_Cars, TB_Bikes, TB_Cars are Satellite tables which hold more info about respective vehicles.
I want users to search using the Name. So, when users enter Name as 'Access', my query should give all information about that vehicle, including that from Satellite Tables (using both TB_Vehicles and TB_Scooters).
SELECT * FROM TB_Vehicles WHERE V_NAME = 'Access';
Similarly, if user enters 'Linea', it should give info from TB_Vehicles and TB_Cars tables.
So, with V_NAME as input, I'll find V_TYPE from TB_Vehicles table, and using that, I need to identify which satellite table, I need to join to retrieve more info.
I have a view that contain multiple tables with ( UNION all ) clause , is there any way that if i query from this view I can explicitly specify the table that i need the data from ?
Let say i have view that contain salaries of 2011
Create view sals_2011 as select * from sals_jan2011 union all sals_feb2011 ..... union all select * from sals_dec2011.
if i issued select * from sals_2011 where emp_id >500 and date < 01-feb-2011 the explain plan show me that full tables and indexes are in processing, while i know that i need only to scan sal_jan2011, and of course it is taking much longer time than selecting from the original table only.
I am trying to create a simple parametised procedure when all I am doing is dynamically inserting data from a set of tables and cols on a where clause.
And for the result set I am also inserting these input variables for future ref.
---------------------------------- CREATE OR REPLACE PROCEDURE DATA_TEST (IN_TABLE_NAME IN VARCHAR2, IN_ATTRIBUTE IN VARCHAR2 ) iS FirstClause VARCHAR2(3000) := 'INSERT INTO ABC ( COL1, COL2, COL3,COL4,COL5, COL6) '; selectClause VARCHAR2(3000) :=
[Code]...
Now, the problem is that the proc is not compiling, because of that escape character.
Is there anything wrong that I am doing or some other settings needs to be done?
I'm joinging two tables event_types and tmp_acc tables.
event_types contains 2 Billion records tmp_acc contains 20,000 records.
Resulting rows are about 300,000 records in event_types table end_t and account_obj_id0 are joined indexed
no indexs in tmp_acc.
When I run below query with nexted loop it takes 6 hrs to complete. But when I run with hash join even after 4 days it was still running. what is wrong with hash join here. Why it takes so long. I'm joining only 20000 rows. So I think there should be a way to get result rows quickly.
show parameters hash_area_size
NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ hash_area_size integer 2097152

The query has a case statement in the where clause so that results can be filtered. If I pass "ut" for sso_id then the query returns 21 rows. If I remove the case statement and hard code "a.sso_id like lower('ut'||'%')" then the query returns 41 rows. The query should be returning 41 rows all the time.
Problem:
When passing "ut" as an SSOID parameter to the Procedure the query returns 21 rows.Taking the query and hard coding "a.sso_id like lower('ut'||'%')" the query returns 41 rows.
Result: query should be returning 41 rows when "ut" is passed an an SSOID parameter.
Returns 21 rows

I have the where cluase as below , I would like to know how does oracle decides which one to execute first,
WHERE S.PERSPECTIVE='S'and s.shipment_gid=sb.shipment_gid AND SB.BILL_GID=CBIL.INVOICE_GIDand inv.invoice_gid=cbil.invoice_gid AND S.SOURCE_LOCATION_GID=LC.LOCATION_GID and l.location_gid=lc.location_gid AND TRUNC(cbil.insert_date)=TRUNC(tc.tesco_cal_date)AND(lc.location_gid='N' OR lc.corporation_gid='TESCO.10719')AND s.source_location_gid=lc.location_gid AND tc.tesco_year='2013' AND tc.tesco_period=6AND tc.tesco_week_number=23
I am trying to export and import tables from oracle...For this i am using imp exp utility...But this is being carried out from cmd prompt...IS there any way by which i can execute these from sql prompt..So that by establishing jdbc connection thgh java code...i cud run the code...
I have a dynamic query which has this clause in it: WHERE [COLUMN NAME] IN (' || theString || ')
My problem is that theString is being passed in through a C# call and the variable is a bunch of strings concatenated together and separated by a comma. Ex: theString = "'val1','val2'"
How many quotes are supposed to go around val1 and val2?
I've tried the following and none work: 'val1','val2' ''val1','val2'' ''val1'',''val2'' '''val1'',''val2''' ''''val1'',''val2''''
When I run the procedure in Oracle it works with '''val1'',''val2'''
I'm using pivot query feature of oracle 11g and came across a strange situation where i need to pass a "select statement" in a "in clause" of pivot query.
I have tried with pivot xml but it not giving desired output in sql*plus session.It is giving unreadable output.
select * from (select uin,testing_id,pfa_result from test1) pivot xml (max(pfa_result) as result for (testing_id) in (select distinct testing_id from test1));
[code]....
Here actually i want to use "select distinct id from test1" instead of "in (11,12,13,14,15)". Because i don't know how many id's will be there and of which values. e.g. 11 or 21 or 25.
send me the command for exporting multiple tables(1000+) in Linux env. 9i db, i know we can do using spool command but dont know exactly how to put it. i know using Datapump but this is 9i.
