Select dates that match from same table.
I wish to update a selection of records
where the order_date is the same, and the customer_id is the same.
The update simply need to be to change the order date on both to the lowest date of the two(or how ever many there are for that date).
e.g.
Ship_date / Order_date / customer_id
1-02-01 2-01-01 1
1-02-01 12-01-01 1
12-01-01 1-01-01 2
12-01-01 5-01-01 2
## So above the first 2 records would have the order_date set to the lowest date of the two records.
A self join ?
Not really sure about this, Thanks in advance!
You could try this (not tested):
UPDATE yourTable t1
SET t1.Order_Date = (SELECT min(t2.Order_date)
FROM yourTable t2
WHERE t2.ship_date = t1.ship_date
AND t2.customer_id = t1.customer_id)However this also updates columns that already have the minimum value. Maybe you would like to avoid it, then add some where clause to the Update statement.
Changed because order_date and ship_date needed to be switched.

Reorganize function will not allow "select rows that match"
I'm trying to sort data in a sheet the same way excel lets you sort by using "filter"
I'm told that using the Reorganize function will allow me to do this especially if I select the "select rows that match" options.
The only problem is that that options is grayed out and I can't use it.
Anybody else have any suggestions or instructions>?
ThanksMake sure you have selected a table

How to handle data that got from SAP by Webservice?
Hi, Gurus.
I am working on IFbA with ABAP and Adobe LiveCycle Designer.
I've developed a function module in R/3 system and created webservice, connected the WSDL address to the form. The problem is how can i handle data that got from SAP by Webservice?
It's Ok if i bind the dataconnection node to the form element, but how can i handle data without binding to the form element? I mean that how can i use the data retrieved from Webserivce in the Javascript, please give me some sample code or script method.
Thanks.Hi Yang,
If you are using Web Service, then the binding will be done automatically.
It can't grow automatically, what else should i do to achieve this?
1.Select the table(make sure you are not selecting subform) in Hierarchy view
2. Under table select the Row which is having the required fileds for data
3. In the Binding of that row, check the checkbox "Repeat Row for each item data" and under that check the Min Count which will set the default row **** to 1

Combine 2 Queries (from SAME table) into a SINGLE query
I have this two queries (from SAME table), and want to combine into one SINGLE query, how?
How can we use CASE WHEN THEN for such situation?
Query1:
SELECT t_inner.*,
Floor(t_inner.ProductiveTime/ 3600) || 'hr:' || LPAD(Floor(Mod(t_inner.ProductiveTime,3600) / 60),2,0) || 'min:' AS Productive_Time,

How to delete master data of materials from sap tables
how to delete master data of materials from sap tables...its needed now.
i know its not recommended but still we need to do this. give me the best possible approach.
regards,
suneethaHi,
I would suggest you not to write your own code to delete the entries.
BAPI_MATERIAL_DELETE, this would mark all materials selected for deletion. But still the material would exist in SAP.
Another solution: Delete a material manually and in another session execute the transaction SM04. This would display the tables which get locked when you do the operation, Then you can write your own code to delete the material numbers from all the related tables.

Selecting from Multiple Tables but requiring data to match from a 3rd table
Hello Everyone,
I'm having alot of trouble with this select
I have three tables:
prod_poured, conc_test, and cyl_breakTo put together my report, I need to grab this data:
cyl_break.pour_no "Pour Number", cyl_break.cyl_id "Cylinder ID", cyl_break.pour_d "Pour Date", conc_test.mix "Mix #", conc_test.amb_t "Ambient Temperature", conc_test.conc_t "Concrete Temperature", conc_test.air "Air %", cyl_break.break_d "Break Date", cyl_break.age "Age (Days)", cyl_break.spec_str "Specified Strength", cyl_break.str "Specimen Strength"and I need it to grab all data in those two tables when one column in the prod_poured table meets a certain condition
This is what I have so far:
select cyl_break.pour_no "Pour Number", cyl_break.cyl_id "Cylinder ID", cyl_break.pour_d "Pour Date", conc_test.mix "Mix #", conc_test.amb_t "Ambient Temperature", conc_test.conc_t "Concrete Temperature", conc_test.air "Air %", cyl_break.break_d "Break Date", cyl_break.age "Age (Days)", cyl_break.spec_str "Specified Strength", cyl_break.str "Specimen Strength"
from conc_test inner join cyl_break on conc_test.pour_no = cyl_break.pour_no, prod_poured
where conc_test.pour_no = prod_poured.test_id and prod_poured.job_no = '9-12-821';It gives me the right results but wayyy too many of them so obviously I've got something wrong.
the results it gives are this:
Pour Number Cylinder ID Pour Date Mix # Ambient Temperature Concrete Temperature Air % Break Date Age (Days) Specified Strength Specimen Strength

Great!
Don't forget to post the INSERT statements, and the output from that data (if it is different from what you posted in your first message).
Basically I need to pull the data I showed above out of conc_test and cyl_break, but only data that has the proper job_number which is retrieved from the prod_poured table. The prod_poured test_id for everything that has the proper prod_poured job_no So an IN-subquery, like Sudhakar and I suggested, should work.
What was the problem when you tried them? Post the query you ran, even if you just copied and pasted it from this thread: there may have be an editing error.
prod_poured test_id is the same thing as conc_test pour_no and cyl_break pour_noExactly! But that doesn't answer the question: Is that value unique in all the tables? If not, in which tables can it be duplicated? -
Creating View based on Current and previous data from same table
I am trying to create a view based on a table called “my_companies”. The table has following columns: “company_id”, “start_date”, “product_type_code”, “partner_id”
The main purpose of this view is to obtain previous company_id’s associated with a particular “partner_id“and “product_type_code”. So basically, I’m looking to create an extra column, say “prev_company_id” in the view along with all the other columns. The “previous” data can be obtained depending on the “start_date”. I’m not able to write a query successfully to do this.
Can anyone help? Thanks in advance.Hi,
Whenver you have a question, it helps to post:
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables
(3) The results you want from that data
(4) Your best attempt so far
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3). Type before and after the tabular text, to preserve spacing. The sample results should include any special cases that you foresee, such as one company having many previous companies, or vice-versa.
It sounds like might need a +self-join+, where you have two copies of the same table, as if the current companies were in one table and the previous companies were in another, even though they are all actually in the same table. -
Data not updating in Metadata with Select options that come from a view
Hi All,
I have a similar problem.
I have a view called "contractnumberview" created in UCM that gets a "contractnumber" from database table called "Contracts"
The view is used as options list for a metadata called "xContractNumber".
The data is inserted in the "Contracts" table from an ADF Application.
Problem:
After a new contract number is inserted into the Contracts table from the adf application, the new contract number does not show up in the check-in form drop down of the xContractNumber metadata field.
If i open the "contractnumberview" from configuration manager, the new contractnumber is listed there.
Is there anything special required to be done so that the contract number is published in the check-in forms also.
Thanks

Any help will be appreciated
Thanks for everybody.

Storing Data in Context from a table (multiple selection)
Hi,
I have created a node called cauverynode, which contains cauName and cauClient as its attribute. I have bound that node with the table. Now i have to store the selected clients into a context. How can i do that? Please help me out. i am unable to store the clients in a string context. Kindly solve it. Below is the code, which will store the selected item and put into a string variable.
public void supplyCauveryNode(IPrivateSampleComponent.ICauveryNodeNode node, IPrivateSampleComponent.IContextElement parentElement)
//@@begin supplyCauveryNode(IWDNode,IWDNodeElement)
IPublicSampleComponent.ICauveryNodeNode cauNode =
wdContext.nodeCauveryNode();
ArrayList selectedcauClients = new ArrayList(cauNode.size());
for (int i = 0, n = cauNode.size(); i < n; ++i) {
if (cauNode.isMultiSelected(i) || i == cauNode.getLeadSelection())
selectedcauClients.add(cauNode.getElementAt(i));
String strSelcaucli = null;
for (int i = 0, n = selectedcauClients.size(); i < n; i++) {
strSelcaucli = strSelcaucli + selectedcauClients.get(i);
wdContext.currentContextElement().setStrCauveryClient(strSelcaucli);
//@@end
Multiple selected data is been stored in this selectedcauClients arraylist, which is not working. Kindly help me out.
Thanks & Regards,
DhanaWhat is the following code supposed to do?
String strSelcaucli = null;
for (int ix = 0, n = selectedcauClients.size(); ix < n; ix++) {
strSelcaucli = strSelcaucli + selectedcauClients.get(ix);
wdContext.currentContextElement().setStrCauveryClient(strSelcaucli);
I guess you want to create a string containing the names(?) of all selected elements.
Then you should use something like
StringBuffer sb = new StringBuffer();
for (Iterator it = selectedcauClients.iterator(); it.hasNext(); )
ICauveryNodeElement e = (ICauveryNodeElement) it.next();
sb.append(e.getName());
if ( it.hasNext() ) sb.append(",");
String csv = sb.toString();
This gives you a comma-separated list of the names of the selected elements.

How to convert data when transferring from one table to another
I have two tables and these are the structure of the tables
create table E1(
ID NUMBER
,NAME VARCHAR2(30)
, DESIGNATION VARCHAR2(30)
,GENDER VARCHAR2(10));
create table E2(
ID NUMBER
,NAME VARCHAR2(30)
, DESIGNATION VARCHAR2(3)
,GENDER NUMBER); Now I want to transfer records from one table to another using a master tables where data are compared because the datatypes in tables are different
The first one is a gender table to match the gender and convert
create table Gender(
E1 varchar2(10),
E2 number);The second is for the designation
create table Designation(
E1 varchar2(30),
E2 varchar2(3);How to match and convert the data so that it can be transfered.Peeyush wrote:
Can we do it with the help of a cursor.
All SQL executed by the database are parsed as cursors and executed as cursors.
I mean I have to insert data in bulk and I want to use cursor for it.The read and write (select and insert) are done by the SQL engine. The read part reads data and passes it to the write part that inserts the data.
Now why would using PL/SQL and bulk processing make this faster? It will reside in-between the read part and the write part being done by the SQL engine.
So the SQL engine reads the data. This then travels all the way to the PL/SQL engine as a bulk collect. PL./SQL then issues an insert (the write part to be done by the SQL engine). And now this very same data travels all the way from the PL/SQL engine to the SQL engine for insertion.
So just how is this approach, where you add extra travel time to data, faster?
and i want to commit the transaction after every 50 recordsWhy? What makes you think this is better? What makes you think you have a problem with not committing every 50 rows? -
Report with multiple COUNT columns with counts from same table
I am new to discoverer so I am a bit lost.
I am working to create a report to show usage data from the eBusiness Knowledge Base. I have the query written in SQL using subqueries that is in the format:
Solution Number | Soultion Title | Solution Views | Positive Feedback | Negative Feedback
12345 ___________ Title ________ 345 ____________ 98 _______________ 34
The 'Views', 'Positive' and 'Negative' entries are stored in the same table so i am doing a count where setid=setid and usedtype=VS, then counting where usedtype=PF and usedtype=NF
In discoverer I can get the solution number, title and ONE of the totals but I can't seem to figure out how to get a COUNT for three different things from the same table in columns on the same row.
When I go to edit sheet -> select items once I select the COUNT option for the UsedType column in the table CS_KB_SET_USED_HISTS I can't select it again. I also have found now way to add a column based on an entered query.
If anyone could help it would be much appreciated.
Thanks

added ______ to correct spacing.Hi,
You can separate the column by using a case or decode.
for example create 2 calculations:
case
when usedtype='PF'
then <you original column> --- the one contain them both
else 0
end
case
when usedtype='NF'
then <you original column> --- the one contain them both
else 0
end
after that you can create the count aggregation over those.

Parent/child records from same table
I want to create a query that is a union such that the 2nd resultset is based on the 1st resultset. I have a table that has parent/child records in the same table.
Table: EVENTS
EVENT_ID
PARENT_EVENT_ID
CREATED_DATE
(other columns)
if PARENT_EVENT_ID is null then it is a parent record, else it is a child record. I want to select all parent records then union them with all the associated child records...something like this:
select * from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null -- All parents
union
select * from EVENTS where PARENT_EVENT_ID in (select EVENT_ID from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null) -- include any children of parents selected from above
This works but it's kind of ugly, I want to avoid using the sub-select in the 2nd because it is a repeat of the 1st statement, is there a way to alias the first statement and just refer to it in the 2nd query?Hi,

Thanks, one question...
I did a test and it seems the child rows have to also satisfy the parent row's where clause, take this example:
EVENT_ID|PARENT_EVENT_ID|CREATED_DATE
2438 | (null) | April 9 2013
2439 | 2438 | April 11 2013
2440 | 2438 | April 11 2013
select * from EVENTS where CREATED_DATE < sysdate - 9
start with EVENT_ID = 2438
connect by PARENT_EVENT_ID = prior EVENT_IDSo you've changed the condition about only wanting roots and their children, and now you want descendants at all levels.
This pulls in record #2438 (per the sysdate - 9 condition) but 2439 and 2440 are not connected. Is there a way to supress the where clause evaluation for the child records? I just want to pull ALL child records associated with the parent and only want to do the date check on the parent.Since the roots (the only rows you want to exclude) have LEVEL=1, you can get the results you requested like this:
WHERE created_date < SYSDATE - 9
OR LEVEL > 1However, since you're not ruling out the grandchildren and great-grandchildren any more, why wouldn't you just say:
SELECT *
FROM events
WHERE created_date < SYSDATE - 9
OR parent_event_id IS NOT NULL;?
CONNECT BY is slow. Don't use it if you don't need it.
If you x-reference my original query:
select * from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null -- All parents
union
select * from EVENTS where PARENT_EVENT_ID in (select EVENT_ID from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null) -- include any children of parents selected from above
The 2nd select does not apply the created_date < sysdate - 90 on the children but rather pulls in all related children :)Sorry; my mistake. That's what happens when you don't post sample data, and desired results; people can't test their solutions and find mistakes like that. -
Query to select values that match multiple ranges
Hi,
Oracle 10g.
I have a table POINTS(ID INTEGER, CLASS VARCHAR2(15), CUMUL NUMBER(2,1), ...).
In my application (APEX application), I show a list of point classes, order by cumul.
SELECT CLASS FROM POINTS ORDER BY CUMUL;Then user can choose some range of point classes (CUMUL is not shown in the application, it is just for the example) :
CUMUL CLASS
12.2 31458 <-
13.4 5S84 <- range 1
13.6 78PPH <-
15.0 3R594 <-
15.1 ZB452
15.5 54IO
17.6 21GFD
19.2 A54VV <-
19.9 IC112 <- range 2
20.8 158RC9 <-
21.3 G4G5
23.0 V22 <- range 3For each range, I store only first and last classes selected by a user, in a table USER_SELECTION(ID, ID_USER, FROM_CLASS, TO_CLASS), so using the example above it would give :
ID ID_USER FROM_CLASS TO_CLASS
1 12 31458 3R594
2 12 A54VV 158RC9
3 12 V22 V22
... ... ... ...The problem is that in a query, I need to return all points selected by a user, and I really don't know how to achieve that without too much work... :
SELECT *
FROM POINTS
WHERE USER_ID=12
AND CLASS IN ( *???* );
Any help would be much appreciated.
Yann.It's not exactly clear what data is in what tables etc. but perhaps something like this...
select user_selection.id, points.*
from points, user_selection
where user_selection.user_id = 12
and points.cumul between
(select cumul from points where class = user_selection.class1)
and
(select cumul from points where class = user_selection.class2)
order by user_select.id, points.cumul -
How to select all the colomns_names from a table, with their datatypes ..
hi :)
i would like to know, how to select in SQL all the columns names from a table with their datatypes so that i get something like this :
Table 1 : table_name
the column ID has the Datatype NUMBER
the column name has the Datatype Varchar2
Table 2 : table_name
the column check has the Datatype NUMBER
the column air has the Datatype Varchar2
and that has to be for all the tables that i own ! ..
P. S : i m trying to do this with java, so it s would be enough if you just tell me how to select all the tables_names with all their colums_names and with all their datatypes ! ..
thank you :)
i ve heard it can be done with USER_TABLES .. but i have no idea how :( ..
Edited by: user8865125 on 17.05.2011 12:22Hi,
The data dictionary view USER_TAB_COLUMNS has one row for every column in every table in your schema. The columns TABLE_NAME, COLUMN_NAME and DATA_TYPE have all the information you need.
Another data dictionary view, USER_TABLES, may be useful, too. It has one row pre table. -
Select query for fetching from 3 tables.
Can we have a single Select query for fetching same fields (kappl,kschl,vkorg,vtweg,spart,kunwe,datbi,knuma,datab,knumh)
from 3 tables >> KOTE707,KOTE708 and KOTE709 into an internal table for a particular KUNNR?
Regards,
Shashank.Hi,
If you have kunnr field in all the 3 tables then it is possible. use inner join as below
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
fldate TYPE sflight-fldate,
carrname TYPE scarr-carrname,
connid TYPE spfli-connid,
END OF wa.
DATA itab LIKE SORTED TABLE OF wa
WITH UNIQUE KEY fldate carrname connid.
SELECT c~carrname p~connid f~fldate
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( scarr AS c
INNER JOIN spfli AS p ON p~carrid = c~carrid
AND p~cityfrom = p_cityfr
AND p~cityto = p_cityto )
INNER JOIN sflight AS f ON f~carrid = p~carrid
AND f~connid = p~connid ).
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
