Update from different table

i have a problem.
i have two tables. one with cities and their population numbers
and another with states and their population numbers.
is there a way to update the states population column strait from the numbers of the cities
population and to make sure that if i change the numbers in the cities then the numbers in the states will also change?

try this
>
update (select s.state,s.state_population, c.state,c.city,c.city_population
from cities c, states s where s.state=c.state)
set s.state=c.state , s.state_population=c.city_population

Report using Data from different tables

Hello,
I am trying to convert a Cobol batch program to Oracle 6i tabular report.
The data is fetched from many different tables and there are lots of processing(i.e, based on the value of a column from one table need additional processing from different tables) required to generate the desired columns in the final report.
I would like to know what is the best strategy to follow in Oracle Reports 6i. I heard that CREATE GLOBAL TEMPORARY TABLE is an option. ( or REF CURSOR ?) I do not know much about its usage. Can somebody guide me about this or any other better way to achieve the result.
Thank you in advance
Priya

Hello,
There are many, many options available to you, each of which has advantages and disadvantages. This is why it is difficult to answer "what is best?" without alot more details about your specific circumstances.
In general, you're going to be writing PL/SQL to do any conditional logic that cannot be expressed as pure SQL. It can executed in the database, or it can executed within Reports itself. And most reports developers do some of both.
As a general rule, you want to send only the data you need from the database to the report. This means you want to do as much filtering and aggregating of the data as is readily possible within the database. If this cannot be expressed as plain SQL queries, then you'll want to create a stored procedures to help do this work.
Generally, the PL/SQL you create for executing within the report should be focused on control of the formatting, such as controlling whether a field is visible, or controlling display attributes for conditional formatting.
But these are not hard and fast rules. In some cases, it is difficult to get all the stored procedures you might like installed into the database. Perhaps the dba is reluctant to let you install that many stored procedures. Perhaps there are restrictions when and how often updates can be made to stored procedures in a production database, which makes it difficult to incrementally adjust your reports based on user feedback. Or perhaps there are restrictions for how long queries are allowed to run.
So, Reports offers lots of options and features to let you do data manipulation operations from within the report data model.
In any case, Oracle does offer temporary table capabilities. You can populate a temp table by running stored procedures that do queries, calculations and aggregations. And you can define and initiate a dynamic query statement within the database and pass a handle to this query off to the report to execute (ref cursor).
From the reports side, you can have as many queries as you want in the data model, arranged in any hierarchy via links. You can parameterize and change the queries dynamically using bind variables and lexicals. And you can add calculations, aggregations, and filters.
Again, most people do data manipulation both in the database and in Reports, using the database for what it excels at, and Reports for what it excels at.
Hope this helps.

TEXT ITEM from different table

When a TEXT ITEM from different table exists in the DATA BLOCK,
and when after EXECUTE_QUERY (in trigger POST_QUERY) we issue
the SELECT for filling the TEXT ITEM from different table, how
we can prevent FROM_STATUS and RECORD_STATUS to get the
value "CHANGED" (because othervise COMMIT is updating all the
records which are the result of EXECUTE_QUERY)?

Set the record status back to query in Post Query trigger:
SET_RECORD_PROPERTY(:SYSTEM.TRIGGER_RECORD, 'BLOCK_NAME', STATUS
, QUERY_STATUS);

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

How to display multiple data from different table in one table? please help

Hi
I got sun java studio creator 2(the separate installation not the one in the net beans)....
My question is about displaying data that have been taken from the database.... I know how to display data in a table(just click on the table "bind data" )... but my question is that:
when i want to use a sql statement that taken the data from different table...
how can i display that data in the table(that will be shown in the web) ??? when i click bind data on the table i can only select one table i can't select more than one....
Note:
1) i'm using the rowset for displaying the data in the table, since the sql statement is depending on a condition(i.e. select a from b where c= ? )...
2) i mean by different table is that( i.e. select a from table1,table2 )..
thanks in advance...

I want display the details of emp table.. for that I am using this SQL statement.
select * from emp where mgr=nvl(:mgr,mgr);
when I give the input as 7698 it is displaying the corresponding records... and also when I won't give any input then it is displaying all the records except the mgr with null values.
1)I want to display all the records when I won't give any input including nulls
2)I want to display all the records who's mgr is null
Is there any way to incorporate to include all these in a single query..It's a little unclear what you're asking.
The following query always includes rows where mgr is NULL, and when the bind variable :mgr is NULL, it displays all rows:
SELECT *
FROM     emp
WHERE     LNNVL (mgr != :mgr)
;That is, when :mgr = 7698, it displays 6 rows, and when :mgr is NULL it displays 14 rows (assuming you're using the Oracle-supplied scott.emp table).
The following query includes rows where mgr is NULL only when the bind variable :mgr is NULL, in which case it displays all rows:
SELECT     *
FROM     emp
WHERE     :mgr     = mgr
OR      :mgr      IS NULL
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL it displays 14 rows.
The following query includes rows where mgr is NULL only when the bind variab;e :mgr is NULL, in which case it displays only the rows where mgr is NULL. That is, it treats NULL as a value:
SELECT     *
FROM     emp
WHERE     DECODE ( mgr
            , :mgr, 'OK'
            )     = 'OK'
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL, it displays 1 row.

How to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,
v_dstat LIKE marc-dstat,
END OF str_table,
i_table1 TYPE STANDARD TABLE OF str_table1.
DATA:
BEGIN OF str_table2,
v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.

Retriving of data from different tables

retriving of data from different tables depening of the primary key this key field is there in all tables if it is there in one v table it should continue to other tables otherwise it should get exit from that it should display information message or otherwise success message if it is there in all tables .

Im writing the concept, just check it.
SELECT * from kna1 into lt_kna1.
if sy-subrc eq 0.
selest * from lfa1 into lt_lfa1
for all entries in lt_kna1.
endif.

Retrieving Data from different Tables with same tuple name

Hi,
I am made the following query from different tables. A tuple "name" is appearing in some tables. So when I run the qiery in a Java class, it delivers the same result of c.name, bpl.name and p.name. The result of c.name is correct, but the other 2 names are overwritten. It works perfect in a postgreSql query tool. How can I correct it, plz?
SELECT c.ad_client_id, c.name, o.c_order_id, o.ref_order_id, bp.name, bpl.name, o.dateordered, o.datepromised, od.c_orderline_id,p.m_product_id,p.name, cur.iso_code, od.qtyordered
FROM adempiere.ad_client c, adempiere.c_order o, adempiere.c_orderline od, adempiere.c_bpartner bp, adempiere.m_product p, adempiere.c_bpartner_location bpl, adempiere.c_currency cur
WHERE c.ad_client_id =11 and c.ad_client_id = o.ad_client_id and bp.c_bpartner_id=o.c_bpartner_id and o.c_order_id = od.c_order_id and od.m_product_id = p.m_product_id and o.c_bpartner_location_id =bpl.c_bpartner_location_id and o.c_currency_id=cur.c_currency_id;
Cheers

Hi,
create alias, if u have similar field names as below. Use the alias name (rs.getString("cname") and rs.getString("bpname") and so on ) to retrive data.
SELECT c.ad_client_id, c.name as cname, o.c_order_id, o.ref_order_id, bp.name as bpname, bpl.name as bplname, o.dateordered, o.datepromised, od.c_orderline_id,p.m_product_id,p.name as pname, cur.iso_code, od.qtyordered

Field selection from differant tables

hello all,
         i need to select differant fields from differant tables when i select common fields from both the tables, is it necessary that the common field need to be a primary key in both tables.
thanks in advance
seenu

HI,
    No its not required that the common field be part of the primary key in both tables only thing is you need to prefix the table name if the field names are same. But if you are using a INNER JOIN then there is no need to select both fields since you know the content of both fields will be same if JOIN is ON these fileds as well.

Deploy update from different pc

Hi, if publish an update from different pc of the last publish, all file are deployed.
I've tried to set <MSDeployUseChecksum>true</MSDeployUseChecksum> in
LightSwitchProfile.pubxml, but is ignored.
Any suggestion is apreciated!

I will try to explain better, with last update published with pc in office:
1) If I publish the update from same pc, only new file are published
2) If the update is published from another pc, with same ntp/DC time source, all files are deployed agai
HI,
Web Deploy has two methods of determining which files will be synced when a publish operation is performed.
Use file time stamps
Use the CRC (Cyclic Redundancy Check) checksum
By default Visual Studio uses the time stamps method. Please follow the Lightswitch team blog to publish updates for app offline and usechecksum. see:
Web publishing updates for app offline and usechecksum
If it still has same issue, please don't hesitate to let me know.

Fetch data from different tables print them is assigned places

Hi Friends,
I have designed one SMART-Form (Receipt).
I need to fetch data from different tables and the data must be print in assigned places. Please help me how to achieve this requirement. Thanks for your help.
Best regards,
Manju.
Edited by: Alvaro Tejada Galindo on Feb 12, 2008 10:20 AM

U're right.
When it creates a smartform it needs to decide when the main data have to be extracted:
- or in driver program
- or in smartforms
The difference can be in the performance, because the program can select the data only once, the smartforms needs to extract them everytime it's called.
I prefer to use a complex structure for the smartform interface as so all data I need are in only one structure, the problem is the complex structure is harder to be managed.

How to update multiple columns from different tables using cursor.

Hi,
i have two tables test1 and test2. i want to udpate the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
     LOOP
          FETCH C1 INTO v_mydept1,v_mydept2;
          EXIT WHEN C1%NOTFOUND;
          UPDATE TEST2 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
          UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
     END LOOP;
     COMMIT;
END;
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.
Can anyone help me on this ?

oops my mistake.....typo mistake...it should have been as follows --
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
Now here is the upated PL/SQL code where we are trying to update columns of different tables --
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO v_mydept1,v_mydept2;
EXIT WHEN C1%NOTFOUND;
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
END LOOP;
COMMIT;
END;
Please let us know why it is not updating by using using CURRENT OF

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)
