Generate query from other table

Hello,
I have stored all the column names of table A in table B .
Here is table A columns
ID
NAME
LENGTH
STREET
ZIPCODE
TALUK
DISTRICT
Here is columns of table B
COLUMN_NAME
DISPLAY
DISPLAY_ORDER
Here is data of table B
COLUMN_NAME DISPLAY DISPLAY_ORDER
ID 0 1
NAME 1 2
LENGTH 1 7
STREET 1 3
ZIPCODE 1 6
TALUK 0 4
DISTRICT 0 5
Now I need a query to select the columns of Table A whose DISPLAY equal to 1 in table B. Something like this.
Select (select COLUMN_NAME from B where DISPLAY=1 order by DISPLAY_ORDER) from A
Or
can I generate query like this from table B based on values of display and display_order?
select name, street,zipcode,length from A
Thanks,
Sujnan

From your table structure i can understand you are using TABLE_B as a user template where user tells what are all the column he wants and in which order he wants.
We have some templates like this. What we have done is like this.
1. A back end program will return all the columns (a static set of columns. and columns names represented individually. using * is not a good practice) to the front end application.
2. And the front end will map those columns available in the template to the screen. And there by the user gets to see only the columns that he selected.
If you cant use such a model then only option you will be left with is to build your query dynamically. And Dynamic SQL has its own set of issues.
Thanks,
Karthick.

Insert into one table by query from other table

Dear sir, i have inserted in to Table A as below:

I want to insert the same more value for field ROLE_ID, USER_ID and AUTH_STAT, except BRANCH_CODE must change. Value of field BRANCH_CODE in can query form Table B.
Kindly give me some idea.

Dbms_xmlgen.newcontext query from multiple tables and ||

I have two questions
How do I get a dbms_xmlgen.context to query from multiple tables? I have been able to make it work with using one table only, but not with multiple tables.
And how to get the || (concat) to work within my query for my output to an xml file?
Here is my current query:
create or replace function get_xml return clob is
result clob;
qryctx dbms_xmlgen.ctxHandle;
SELECT DBMS_XMLGEN.getxml('select prefix, suffix, fiscal_yr
FROM rcv.recv_accessions ra
where ra.prefix = 8 and ra.fiscal_yr = 11')xml into result FROM dual;
result := DBMS_XMLGEN.getXML(qryCtx);
This is what I desire:
SELECT DBMS_XMLGEN.getxml('select ra.prefix||'-'|| ra.suffix||'-'|| ra.fiscal_yr accession, ss.date_in, st.test
FROM rcv.recv_accessions ra, ser.sero_samples ss, ser.sero_tests st
where ra.prefix = 8 and ra.fiscal_yr = 11 and ss.raid = ra.id and st.ssid = ss.id')xml into result FROM dual;
On this both the reference to multiple tables and the concat function cause errors.
Thank you

Hi,
for the concat do I use xmlconcat?No, XMLConcat is used to concatenate XMLType fragments.
The || operator will do fine, but you must escape any single quote inside the string :
SELECT DBMS_XMLGEN.getxml(
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id'
INTO result
FROM dual;Or, use the quoting operator to define a custom string delimiter :
SELECT DBMS_XMLGEN.getxml(
q'{SELECT ra.prefix ||'-'|| ra.suffix ||'-'|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id
INTO result
FROM dual;BTW, a good practice would be to use bind variables for the query. DBMS_XMLGEN can handle them nicely :
CREATE OR REPLACE FUNCTION get_xml
RETURN CLOB
IS
qryctx   DBMS_XMLGEN.ctxHandle;
v_out    CLOB;
qrystr   VARCHAR2(4000) :=
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = :b_prefix
AND ra.fiscal_yr = :b_fiscal_yr
AND ss.raid = ra.id
AND st.ssid = ss.id';
BEGIN
qryctx := DBMS_XMLGEN.newContext(qrystr);
DBMS_XMLGEN.setBindValue(qryctx, 'b_prefix', '8');
DBMS_XMLGEN.setBindValue(qryctx, 'b_fiscal_yr', '11');
-- to generate empty elements if necessary :
DBMS_XMLGEN.setNullHandling(qryctx, DBMS_XMLGEN.EMPTY_TAG);
v_out := DBMS_XMLGEN.getXML(qryctx);
DBMS_XMLGEN.closeContext(qryctx);
RETURN v_out;
END;

How to generate report from two tables using DAO design pattern?

Hi,
Iam using struts with DAO pattern for my application. According to DAO design im creating model class for each table in my database with getter,setter methods. i have no problem when im generating report from one table. but if have i have to join two tables whatis the better way for doing that? is it good practise to create a new model contains properties from both the tables?
Please help me
Thanks in Advance
Rajesh

Dear Rajesh,
As per the pattern you are creating equivalent java objects for every database table under consideration in which each db field will become a private attribute and public getter and setter methods.
If you have to display data from one table the above approach is sufficient enough.
But in case your database is normalised ..lets take an example of Bank having Branch and Accounts tables. We dont need to repeat the whole information of the branch for every account in that branch. so we prefer to have a branch id in that table....this approach lot of insertion/deletion/updatation anomlies that may exists with the database...
now lets come back to our topic....we shall create two java objects 1) Branch 2) Account.....
When ever u just need to display simple report u can do it staright forward,,,,,now if u want to display branch information along with the account information....the two objects just created are not sufficient
So i suggest u the following approaches
1) Create an attribute of type Branch in the Accounts Object......
This shall serve the purpose of displaying the Btranch information
2) Create a collection object of type ( Vector or ArrayList) which can have objects of Account in the Branch Object,,,
Now its upto u how shall u fill up the objects with appropriate sql queries.
The method that i mentioned is followed by Oracle Toplink and Hibernate ....which provide Object to relation mapping layers.
Any queries ...revert back to me...

At some point in developing iOS apps you would need to use a Mac to upload the app to the App Store. If you have access to a Mac to do that you could also use the same Mac to download your certificate from the iOS developer portal. That certificate can be added to Keychain Access, where it’s very easy to export a P12 file.
If you’re doing the development for a client, have them download the certificate and export the P12 to send to you.

Hi,
Welcome to the forum!
Like the others, I can't see a business purpose for this trigger. I assume it's just an experiment to learn how triggers work.

Are you saying the trigger doesn't fire? It does fire; it just raises the mutating table error, so you don't see anything.

Output, when trying to UPDATE class:3 = schosen entering check_schosen
MUTATING TABLE
1 row updated.
Obviously, the trigger fired, since you see the message "3 = schosen entering check_schosen"
Obviously, the OPEN statement raised an error, since you don't see the message 'Cursor is open now.'
Obviously, the mutating table error was raised, since you see the message 'MUTATING TABLE'.
So the trigger fired, and went to the EXCEPTION handler almost immediately. The EXCEPTION handler printed a message, as instructed, and the trigger ended. Then the actual UPDATE took place.
I hope this answers your question.
If not, what is your question? It may be very clear to you, but a complete mystery to others. Ask clear questions, such as "Why did ... happen? I thought ... would happen, be ... as the PL/SQL manual says at ...".

One more thing : From performance point of view you have to Replace that loop using FOR ALL ENTRIES . And avoid CORRESPONDING FIELDS. it will be slow.
This is the code.

i need to write a oracle procedure, which when called generates xml doc (building xml from different tables in database.). i got the DTDs . but i still dont understand how can the data be pulled from diff tables and put in the one xml? can anyone give me rough idea.. i know that i have to use xmlquery and xml_save packages... but still not much clear..
i m working on oracle 8i database. any help is appreciated.. thanks.

Any feedback to the above questions would be greatly appreciated!

[Help] Join query from 3 tables

Hi, I'm new to database. I have a question about joining 3 tables, pardon me for my bad english.
My tables look like this
table 1: Person (id,firstname, lastname)
table 2: AssignPersonAddress (id,personid,addressid,type)
table 3: Address (id,telefon, street, etc)
I need AssignPersonAddress table, because in my data structure a person can have more than 1 address and the address type should be saved (for eg: private, work)
I want to make a select query to report all of person with his private telefon and work telefon, like this.
PERSON | PRIVATE | WORK
At the moment my query looks like this
select p.name , a1.tel AS Private, a2.tel AS Work
from person p,
addresse a1 ,
AssignPersonAddress apd1,
AssignPersonAddress apd2,
addresse a2
where p.id = apd1.person (+)
and apd1.adresse = a1.id
and apd1.art = 'Private'
and p.objectid = apd2.person (+)
and apd2.adresse = a2.id
and apd2.art = 'Work'the problem is I only get the person who has private and work address. But what I want is all person no matter if the person has only 1 address or 2 address.
As you can see I put the outer left join at the where condition, but I'm still getting the wrong result.
thx in advance

Hi,
You're essentially doing an inner join, because some of the comparisons are missing the + markerr.
Do this instead:
select p.name , a1.tel AS Private, a2.tel AS Work
from      person                p
,      addresse           a1
,      AssignPersonAddress      apd1
,      AssignPersonAddress      apd2
,      addresse           a2
where      p.id           = apd1.person (+)
and      apd1.adresse      = a1.id (+)
and      apd1.art (+)     = 'Private'
and      p.objectid      = apd2.person (+)
and      apd2.adresse      = a2.id (+)
and      apd2.art (+)     = 'Work'
;What does this mean?
where      p.id           = apd1.person (+)It means "include rows from p even if they don't have any matching rows in apd1". Whenever that happens, all the colummns from apd1 will be NULL.
So far, so good.
Now, what happens if you follow that with
and      apd1.adresse      = a1.id The condition above means "include this row from apd1 only if there is matching row in a1". If apd1 is NULL, this condition will never be TRUE (even if a1.id is NULL).
When you do a cascading outer join like this, all columns in the distal table (the table farther away from the table that must be present) need to be marked with the + sign. That includes conditions involving a constant, like
and      apd1.art (+)     = 'Private' By the way, when posting code or results on this site, always type these 6 characters:
(small letters only, inside curly brackets) to preserve spacing and to keep some strings, such as the outer-join marker, form being interpreted as emoticons.

Update from other table

I want to update one table with values from another table. The code I have written looks like
update reservations r
set start_date = (select start_date from sap_update su where su.reservation_id = r.reservationid),
end_date = (select end_date from sap_update su where su.reservation_id = r.reservationid),
impressions_rsvd = (select impressions_rsvd from sap_update su where su.reservation_id = r.reservationid),
sapid = (select sapid from sap_update su where su.reservation_id = r.reservationid),
state = (select reservation_state from sap_update su where su.reservation_id = r.reservationid);
which results in me being told that start_date cannot be set to null.
the intent is to match up records in the reservations table with those in the SAP_UPDATE table (on the reservationid column) and copy the data in corresponding rows from the sap_update to the reservations table.
In passing, I personally find that the more complex inserts and updates are just as nasty as any select query. But all the books I've come across tend to skip over this aspect rather sharply. Are there any good resources on this? I'm also hampered by having rather more SQL Server experience - which seems to have a different handle on updates.
Thanks for your help in anticipation!
Iain

If your subquery is not returning anyrow (i.e. no matching record in Sap_Update table for the given ReservationID), and you don't want to change existing value then in that case you can change it to:
update reservations r
set start_date = (select nvl(su.start_date, r.start_date) from sap_update su
   where su.reservation_id = r.reservationid),
end_date = (select end_date from sap_update su
   where su.reservation_id = r.reservationid),
impressions_rsvd = (select impressions_rsvd from sap_update su
   where su.reservation_id = r.reservationid),
sapid = (select sapid from sap_update su
   where su.reservation_id = r.reservationid),
state = (select reservation_state from sap_update su
   where su.reservation_id = r.reservationid);In similar fashion you can change your other subqueries too. Another suggestion, you can rewrite your query to:
update reservations r
set (start_date, end_date, impressions_rsvd, sapid, state   ) =
(select nvl(su.start_date, r.start_date), end_date , impressions_rsvd, sapid, state
from sap_update su
   where su.reservation_id = r.reservationid)

Query from source table takes lots of time

I have to load data from an Oracle table which has millions of records. The loading knowledge module I am using is 'lkm sql to oracle'.
I see that the query from the source database takes lot of time and doing a full table scan where as it supposed to be using an index.
I dont have any lkm with 'lkm oracle to oracle'. Some how I need to add a hint to this source query. How I can do this?

This LKM is not indicated to large volume of data, try to use LKM Oracle to Oracle (DBLINK), see ODI KMs documentation for more information.
Related to HINTS you can add this with KM options, see that some Oracle ODI11g new KMs already have some options to do it, so you can put the hint on interface options of KM or define the temp index on the interface

Procedure to insert in table from other table returning multiple records

Hi Everybody,
I am new to oracle. So need your advice guys. I have to insert values to one table from another table. Please let me know , how i can do this.
E.g:
INSERT INTO TABLEA(`Name`,`ID`,`another_field`) VALUES ('Somevalue',(SELECT DISTINCT id FROM TABLEB WHERE tb.cat = '5' AND ID NOT IN (select id from TABLEC)), 'somevalue')
Above thing is not working for me.
I have to insert ID IN TABLE A by getting value from this query:
SELECT DISTINCT id FROM TABLEB WHERE tb.cat = '5' AND ID NOT IN (select id from TABLEC)
This query is returning multiple IDs, so how can i insert all in TABLEA by creating some sp.
Please help me out of this. I will be very thankful to you all guys. I will really appreciate your suggestions and comments.
Regards
Dev

Why cant you just do this,
INSERT INTO TABLEA (NAME, ID, another_field)
   SELECT DISTINCT 'Somevalue',
                   ID,
                   'somevalue'
     FROM TABLEB
    WHERE tb.cat = '5'
      AND ID NOT IN (SELECT ID FROM TABLEC)G.

Generate XML from Oracle Table Data

Hi All,
I am new to this network. I am also new to oracle XML package. I want a help for the below query.
CREATE TABLE EMP(ID NUMBER PRIMARY KEY, NAME VARCHAR2(10), PHONE NUMBER);
INSERT INTO EMP(ID,NAME,PHONE) VALUES (11,'Joy',1234);
INSERT INTO EMP(ID,NAME,PHONE) VALUES (22,'Mike',5678);
INSERT INTO EMP(ID,NAME,PHONE) VALUES (33,'Jason',NULL);
COMMIT;
I want to export the EMP table data in a XML file with the below format.
Required Output:
<?xml version="1.0" encoding="UTF-8"?><STATICDATA><EMP><ID>11</ID><NAME>Joy</NAME></EMP></STATICDATA>
<?xml version="1.0" encoding="UTF-8"?><STATICDATA><EMP><ID>22</ID><NAME>Mike</NAME></EMP></STATICDATA>
<?xml version="1.0" encoding="UTF-8"?><STATICDATA><EMP><ID>33</ID><NAME>Jason</NAME></EMP></STATICDATA>
I have used some XML functions and have written the below query.
select XMLROOT(XMLELEMENT(staticdata,XMLELEMENT(EMP,XMLELEMENT(ID,ID),XMLELEMENT(NAME,NAME))), version '1.0" encoding="UTF-8') xml FROM EMP;
output of my query:
<?xml version="1.0" encoding="UTF-8"?>

<EMP>
<ID>11</ID>
<NAME>Joy</NAME>
</EMP>

</STATICDATA>
<?xml version="1.0" encoding="UTF-8"?>
<STATICDATA>
<EMP>
<ID>33</ID>
<NAME>Jason</NAME>
</EMP>

Some things output XML all as one stream, some things naturally display it structured. It doesn't matter as the XML is still the same because by it's very nature it is a structured data definition. Anything that reads XML will be able to read it whether it's on one line (streamed) or structured.
also can i export all the columns of the table by some thing like select * from the table in XML file ?A couple of ways of exporting XML to a file...
-- DBMS_XSLPROCESSOR.clob2file
-- outputs a clob to a file
DECLARE
 ctx DBMS_XMLGEN.ctxtype;
BEGIN
 ctx := DBMS_XMLGEN.newcontext ('select * from emp');
 DBMS_XSLPROCESSOR.clob2file (DBMS_XMLGEN.getxml (ctx), 'TEMP', 'emp.xml');
 DBMS_XMLGEN.closecontext (ctx);

Replace the data in the table from other table

Iam creating a backup of table Order by this query:
create table orderbckup as select * from order; - this works
For the first time i have to create a orderbckup table but every month i have to replace the data in orderbckup from order table. Is there any way where i can copy the data from order and repalce the data in orderbckp - I cannot use insert as it adds the rows. Or do i need to delete the old table and create it again or can i use update. If so can anyone plz let me know

If I understand you, the problem isn't with adding new rows; the problem is how to remove the old rows.
Or do i need to delete the old table and create it again or can i use update. If so can anyone plz let me knowInstead of dropping the table and re-creating it, you can TRUNCATE the table and then use INSERT:
TRUNCATE TABLE orderbackup;
-- At this point, orderbackup has 0 rows
INSERT INTO orderbackup
SELECT *
FROM orders -- ORDER is a reserved word in Oracle, so it's not a good table name
;TRUNCATE TABLE is faster than DELETing all the rows, because it doesn't save redo information. (That means you can't ROLLBACK a TRUNCATE statement, but you can rollback a DROP TABLE statement, either.)
