Help in query from table

Hi,
I am having a strange issue,
i have a table containing the following amgst others
rec_time sys_date
7:00 04/08/2010
8:00 04/08/2010
9:00 05/08/2010
I need to query this table and return the max(rec_time) for all sys_date = sysdate
its not working if i do the following
select max(rec_time) from table
where sys_date = sysdate;

hello,
this is my table structure for hourly_sales
ID                 NUMBER,
PRODUCT            VARCHAR2(25 BYTE)          NOT NULL,
GAME_ID            NUMBER                     NOT NULL,
SYS_DATE           DATE                       NOT NULL,
CONFIRMED          CHAR(1 BYTE)               DEFAULT 'N',
ACT_AMT            NUMBER                     NOT NULL,
CUMM_AMT           NUMBER                     NOT NULL,
COUNT_SALES        NUMBER                     NOT NULL,
CREATED_BY         VARCHAR2(25 BYTE),
CREATION_DATE      DATE,
LAST_UPDATED_BY    VARCHAR2(25 BYTE),
LAST_UPDATED_DATE DATE,
REC_TIME           VARCHAR2(25 BYTE)          NOT NULL,
ORDER_ID           NUMBERI have created a small application in APEX that has an LOV for rec_time from 7.00 to 22.00. this is just an indication to the times that values are being entered.
Now those geezers were making mistakes and the reason why i wanted my query was to enable them to roll-back on a button click
delete from hourly_sales
where rec_time = max(rec_time)
and trunc(sys_date) = trunc(sysdate);but when i was querying it was not returning any values.

Ad Hoc Query from table PPDIT

Hi,
I'm creating an ad hoc query to retrieve data from table PPDIT by filtering the transaction key. This is to get a list of amounts posted to the technical accounts(Transaction key HRA). However, the query output and the output from table PPDIT through SE16 are different. It seems like the query only picks up transaction key HRF. Anyone with any ideas why?

Hi,
Than you add the additional field from extras option.
click on extras tab.
From there add table add field add structure.
If you want to add a field write the name of the field and continue.
suppose the field is matnr.
Long text = material number
header = material number
and in like reference = mara-matnr.
tablename-field name.
let me know if this helps you.

J2IUN Mismatch with query from table J_1IPART2

Hi experts,
If I run the TCODE J2IUN there is a marked difference for the RG23C register BED, AED, Cess, and HCess values that have been taken from table J_1IPART2 for the same period. What could be the cause for these differences and why did they occur or do I have to take addtional records from another table also. Well I am considering the Opening balances also.
Please can you help me regarding this.
Regards
Yao Chhang

You will have to first trace the difference. In the next step, go through J2IUN in debug mode with Abaper & check from where all the data is being picked. Next check whether all the data pick point are considered in Query.

Need help with query from .csv file

I am trying to import a csv file with only 1 column in it.
The column will only contain a 9 digit ID number. I want to read
the file then use the contents to query a table to get the names
and other information and display it. Here is what I have so far:
<cffile action="read" file="#form.FiletoUpload#"
variable="csvfile">
<cfloop index="index" list="#csvfile#">
<cfquery name="massimport" datasource="data1">
SELECT * FROM IDTable
WHERE CardNumber = ('#csvfile#')
</cfquery>
</cfloop>
<cfoutput>#Name# #ID# #Site#</cfoutput>
I get no errors but I am not getting any results. Just a
blank page. Does anyone know how to query directly from a csv
import? Thanks.

You need to convert your file to a list somehow. Not sure if
this is the most efficient way but, you can use the cfhttp tag to
produce a query. Then your where clause becomes,
where cardnumber in (#quotedvaluelist(query.column)#)
and you won't need a loop.

[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.

I can query the data in screen. I need into insert the data into the emp_temp.
I don't know how to do this . Please help me.
Thanks
Subra

You can create a VO based on EO on emp_temp table.....
And u have attached a Different VO on the page... Right...
Now what u can do is....once u click on apply....
u can set the each attributes of EO based VO explicitly via code, from the values of second VO.... and then commit.....
Perhaps this might help...

This can be rewritten as a single query which is good for a
number of reasons, including we only make one trip to the database
and we do our calculations on the SQL backend, which is faster than
doing them in CFML.
What you're going to want to do is SUM() the total
transaction values by having a column like SUM(Num_Checks_Trans *
Value) AS totalTrans. To get the value for your other column you
can calculate that like Num_Checks_Trans / Weekly_Hours_Recorded. I
didn't see the latter in either of your queries so I'm not sure
where it comes from, but you can definitely use it in your SELECT
clause when calculating.
Since SUM() is an aggregate function, you'll have to use a
GROUP BY clause to make it work. You'll have to GROUP BY each
column in the SELECT statement. If some of the columns have
differing data that you won't want to use in the GROUP, you can
always use a nested subquery as part of your FROM clause and then
join that to the original queries with the totals.
I hope that helps.

Fetch Insert / Update Query From Table Trigger

Hi everyone !,
I have a situation, is there any way where I can get insert/update query by before-insert / after insert trigger when a user inserts/updates any row in the table.
Plz....help me....champs.....
Regards,
Naushad

That was a nice thing but it works only on some oracle 9i with DML statements.
On database versions 9.2.0.1 to 9.2.0.6 ora_sql_text works and returns the calling text for dml triggers, where as starting from 9.2.0.7 the behavior has changed and returns NULL.
Cause
This issue had surfaced from 9.2.0.7.0 patchset. After discussions in Bug 4171597 which was closed as a duplicate of Bug 4230721 it was concluded that it was the expected behavior i.e ORA_SQL_TXT should return null when dml triggers are used.
ORA_SQL_TXT is a "System defined event attribute" and is supposed to work only with "System triggers". This is also what the Documentation says - "Application Developers Guide : Fundamentals(9.2)
Chapter 16 Working with System events".

Query from table a and insert to table b

Hi,
I would like to create an attendance page to record student's attendance on a particular dates.
I have 2 tables - students and attendance tables; in which attendance table will consist of PK from students table and date.
How do I create a form that display all the students record in a page with checkbox and date column; and when user check the boxes and click save; it will insert record into attendance table? Thanks!
Layout similar to the below:
Date: 1/1/2010 (user input)
Name: Attend
student 1 (checkbox)
student 2 (checkbox)
student 3 (checkbox)
student 4 (checkbox)
.....

Hi Aaron,
For this you can do the following
1. Create a Tabular Form on The STUDENT table, i.e. the table you are using as a Fecth only table
2. Make the ApplyMRU and ApplyDRD process conditions Never so they will not be executed
3. Write your own custom process to write the checked rows into Attendence Table.
In the process you will have to refer to the checkbox f+nn+ item using APEX_APPLICATION.G_F+nn+ array and write from similar arrays for the other tabular form items
You will find useful code snippets in the Apex Help , Advanc3ed Tutorials as well as here http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html#MANUAL

Help with query to return results from group within table?

Hi
Im a total noob, so please be gentle....!
I am looking at a table that has a WORD column and a WORD_TYPE_ID column.
Words can have the same type_id.
What I am trying to do is write a query that will return the longest word for each word_type_id.
I have been trying for hours to get this and all I seem to get is either error messages or I return the longest word in the whole WORD column.
The furthest I can get before things break down is.....
select word
from table
where
length(word) =
select
max(length(word))
from table
Any help on this or if I could be pointed in the right direction it would be greatly appreciated.
Thanks

Hi,
Welcome to the forum!
Here's one way:
SELECT    word_type_id
,       MIN (word) KEEP (DENSE_RANK LAST ORDDER BY LENGTH (word))     AS longest_word
FROM       table_x
GROUP BY word_type_id;If there happens to be a tie within some word_type_id (that is, 2 or more words have exactly the same length, which is the longest in that group) the expression above will return the first one, in alphabetic order. (That's what MIN means here.)
Edited by: Frank Kulash on Aug 11, 2009 1:56 PM
You almost had it.
As you noticed, you were getting the longest row in the whole table. That's because your sub-query was looking at the whole table.
If you correlate the sub-query to the row in the main table, as shown below, you can get the longest word in each group:
select word
from     table     m                              -- m for main
where      length (word) = (
                            select max (length(word))
               from     table
               where     word_type_id = m.word_type_id     -- New
               );

Pagination query help needed for large table - force a different index

I'm using a slight modification of the pagination query from over at Ask Tom's: [http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html]
Mine looks like this when fetching the first 100 rows of all members with last name Smith, ordered by join date:
SELECT members.*
FROM members,
    SELECT RID, rownum rnum
    FROM
        SELECT rowid as RID
        FROM members
        WHERE last_name = 'Smith'
        ORDER BY joindate
    WHERE rownum <= 100
WHERE rnum >= 1
         and RID = members.rowidThe difference between this and the one at Ask Tom's is that my innermost query just returns the ROWID. Then in the outermost query we join the ROWIDs returned to the members table, after we have pruned the ROWIDs down to only the chunk of 100 we want. This makes it MUCH faster (verifiably) on our large tables, as it is able to use the index on the innermost query (well... read on).
The problem I have is this:
SELECT rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateThis will use the index for the predicate column (last_name) instead of the unique index I have defined for the joindate column (joindate, sequence). (Verifiable with explain plan). It is much slower this way on a large table. So I can hint it using either of the following methods:
SELECT /*+ index(members, joindate_idx) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
SELECT /*+ first_rows(100) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateEither way, it now uses the index of the ORDER BY column (joindate_idx), so now it is much faster as it does not have to do a sort (remember, VERY large table, millions of records). So that seems good. But now, on my outermost query, I join the rowid with the meaningful columns of data from the members table, as commented below:
SELECT members.*      -- Select all data from members table
FROM members,           -- members table added to FROM clause
    SELECT RID, rownum rnum
    FROM
        SELECT /*+ index(members, joindate_idx) */ rowid as RID   -- Hint is ignored now that I am joining in the outer query
        FROM members
        WHERE last_name = 'Smith'
        ORDER BY joindate
    WHERE rownum <= 100
WHERE rnum >= 1
        and RID = members.rowid           -- Merge the members table on the rowid we pulled from the inner queriesOnce I do this join, it goes back to using the predicate index (last_name) and has to perform the sort once it finds all matching values (which can be a lot in this table, there is high cardinality on some columns).
So my question is, in the full query above, is there any way I can get it to use the ORDER BY column for indexing to prevent it from having to do a sort? The join is what causes it to revert back to using the predicate index, even with hints. Remove the join and just return the ROWIDs for those 100 records and it flies, even on 10 million records.
It'd be great if there was some generic hint that could accomplish this, such that if we change the table/columns/indexes, we don't need to change the hint (the FIRST_ROWS hint is a good example of this, while the INDEX hint is the opposite), but any help would be appreciated. I can provide explain plans for any of the above if needed.
Thanks!

Lakmal (and OP),
Not sure what advantage you are trying to show here. But considering that we are talking about pagination query here and order of records is important, your 2 queries will not always generate output in same order. Here is the test case:

SQL> set autotrace off
SQL> spool offAs you will see, the join query here has to have an ORDER BY clause at the end to ensure that records are correctly sorted. You can not rely on optimizer choosing NESTED LOOP join method and, as above example shows, when optimizer chooses HASH JOIN, oracle is free to return rows in no particular order.
The query that does not involve join always returns rows in the desired order. Adding an ORDER BY does add a step in the plan for the query using join but does not affect the other query.

SAP Query - Additional field that collects information from table RESB

Hello gurus. I have a question.
I want to create a SAP Query that shows me the stock level of a list of materials, and also show me the total quantity of order reservations in an additional field.
I created an InfoSet with table MARD, which is the one that holds the Stock information in a plant. Then I created an additional field which would read information from table RESB, the table that holds order reservations per material.
So I wrote this piece of code:
SELECT * FROM RESB
WHERE MATNR EQ MARD-MATNR and
       WERKS EQ MARD-WERKS.
ENDSELECT.
if ( sy-dbcnt NE '0').
      MOVE RESB-BDMNG to ZQTY.
ELSE.
      MOVE '' to ZQTY.
ENDIF.
This works fine. However, this is currently just catching the first record in table RESB that matches my condition.
What I would like is to collect every instance of RESB-BDMNG and add them to field "ZQTY", have it loop in RESB until it finishes finding every record that match the MATNR and WERKS. With this I could get the total number of order reservations that this material has in that table.
Could someone share some coding that would help me achieve this?

Yes! That did it. That's what I needed to do. Thank you so much.
While I'm at it, let me ask you a related question.
When I execute the query, in the first records of the query where there's no value from RESB to transfer, the value of field ZQTY appears empty. Once it finds the first record in RESB and it populates ZQTY with a value, then the rest of the records with no hit get the proper value of 0.
Do you know why the first records in the query appear empty and not with a 0? Is there anything I should add to the coding to fix this?
