Forms :: Data Block Ignoring Order By Clause?
Mar 6, 2012
I have a real problem with form, specifically one of its data blocks. In the order by property of the block i specify it to sort on a branch in ascending order(i tried descending as well) but for some reason the form ignores that and sorts it on the ROWNUM. I even removed the where clause, the order by clause and changed the query data source type to FROM clause and changed the data source name to pre-query. I then created the query string in the block's pre-query trigger and set query_data_source_name property to that query string and still the data in the block is not being sorted on the branch number but instead on the ROWNUM.

I have two block....both are the control block.. in first block i select the date and in second block the data of that date is populated.but the data is populated using cursor in when-button-pressed trigger of that first block button.in cursor the data is selected and placed in field of detail block using into clause.... each field and one item of detail block is srno which is create in post-query of detail block using :sysyem.trigger_record.
Now i want after populated the detail block the data is sorted desc one of the field of the detail block..Can this possible using set_block_property() of block although the block is control block if yes where i should do this?

I want to use a sequence to populate a field for my insert statement. Should be simple right?
So here is an example
insert into sometable ( seq, else)
select
myseq.nextval
,somethingelse
from sometable@dblink
where somethingelse = 10
now if i remove my sequence call for nextval it correctly uses the where clause but when I use the sequence in the select statement it is ignoring the where clause completely. I've never had this issue before...is this because i'm using a dblink now?
I'm using toad 10 on oracle 11g in multi-schema environment.

I have data block that has hundreds of records. On a screen I display 20 records at a time. On that same screen I have "find badge" function where user types badge/employee id and presses a button to find the record in a data block. I have no problem finding the records in a list and pointing the curser to appropriate record. My question is (which is a user request) if the badge/employee id is found to make that record to be the first record in a list.

I have requirement to create an XML structure through stored procedure. I need to Order some of the columns in ascending order before I format them into the xml structure. I am pretty novice to creating an output into XML format, but attached is the query I came up with (without order by). This works perfect, but now the requirement is to order by - cls_cd, and within cls_cd, again order by - cat_cd. I am not able to do this.

I have a requirement where I need to display a list of employees, performance rating and manager id. I want to display the employees first whose manager is as manager_id as input parameter. So lets say a manager logs in, he should see his reporters first and then the rest. How can I implement this in SQL? I am trying first clause with order by but not sure how to do that here.
procedure
display_list(manager_id in varchar2)
Output is:
emp_id
manager_id
performance_rating

I know that order by clause in normal query is used to order the result set based on the key. significance of order by clause in analytical functions.
with data as
(select empno,
sal,
case
[Code]...
In case of min, max analytical functions order by clause have importance. But how it will work for a COUNT function ?

I have got the following error while executing below Query.
ORA-01791 'Not a SELECTed expression'
select distinct sgbstdn_levl_code
from sgbstdn,spriden
where spriden_pidm = sgbstdn_pidm
and spriden_id = '200076543'
order by sgbstdn_term_code_eff desc;
The above Query is not working with Distinct & Order By clause are present and by joining two tables. I need the distinct values of levels in Descending order of Terms.

When i try to execute a query, which is organised as the below example, it retrieves data..
select * from (
select col1, col2, col3, col4....coln
from TABLE_ONE left outer join TABLE_TWO
-- some conditions and group by clause
order by 1 asc
)
where rownum <=1000;
Again if I use Column alias in the ORDER BY clause col1, the query won't retrieve data.
Also If I use ORDER BY 4 instead of ORDER BY 1, the query wont return data...
select * from (
select col1, col2, col3, col4....coln
from TABLE_ONE left outer join TABLE_TWO
-- some conditions and group by clause
order by 4 asc
)
where rownum <=1000;
The whole issue revolves around the inner ORDER BY Clause and external ROWNUM condition..If I eliminate any of the two, the query works fine...I am not sure if indexes have some role to play in it...

Oracle version : 11.2.0.2 Linux EL6 server
I have a query like below:
select col1, col2, col3, col4
from tab1, tab2, tab3
where conditions
union
[Code]...
Now, the col4 is a date column and I have to order by the entire result sets on it. I know I can do it by (order by col4) or by (order by 4) at the end of the entire query.
But the problem is that, the output is coming in dd-Mon-yyyy (i.e 31-Nov-2012).
I want every output in dd/mm/yyyy format so I need to use to_char function.
But in that case, I cant use the order by clause, because in that case it is getting arranged by character i.e by 1,2,3,4,5 like this.

currently i m going through some dumps for my OCA-11g prep.I came across one sentence :A view cannot have an ORDER BY clause in the SELECT statement.well this statement is false and the explanation given was :
Query operations containing ORDER BY clause are also permitted, so long as the ORDER BY clause appears outside the parentheses.
The following is an example of what I mean: CREATE VIEW my_view AS (SELECT*FROM emp) ORDER BYempno.
but when i tried running the query like this :CREATE VIEW my_view AS SELECT*FROM emp ORDER BYempno ,it worked w/o giving parentheses.

I came across situation where a Nullable column is not using index for 'order by' clause. I added Not Null condition in the 'where' condition but it wasn't useful. I don't wanted to make composite index with not nullable column or with constant or modify column to 'Not Null'
So I carried out test cases and during which I found that in one case the sql statement does 'fast full scan' for data access but does not use index for 'order by' sorting
here are the steps
Initially I kept the column Nullable
SQL> create sequence s5;
Sequence created.
SQL> create table t5 as select s5.nextval id,a.* from dba_objects a where rownum<1001;
Table created.
SQL> set pages 100
SQL> select column_name,nullable from user_tab_columns where table_name='T5';
SQL> create index i5 on t5(id);
Index created.
SQL> exec dbms_stats.gather_table_stats(user,'T5',cascade=>true);
PL/SQL procedure successfully completed.
exit
SQL> alter session set events '10046 trace name context forever, level 12';
select *
from
t5 where id is not null order by id

Questions are
1) Why adding 'where id is not null wasn't enough for the index to get used in 'order by'?
2) While we got 'fast full scan' why index wasn't used for 'order by' clause?
3) Do we need the indexed column in where clause for being used in 'order by clause' too?
4) Do we need 'order by' clause if we are selecting only the indexed column with sequence generated values?

I am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.

i have created on query block , upon pressing the button there is a wehre clause in the block which will filter the records based on all alike items from two tables but my problem is , in one table there is no information of struct and in other there is struct information or data, what i want is even if i pass a parameter in the where clause all the records should be filtered.
CREATE TABLE OT_ACTUAL_ACT (ITEM_CODE VARCHAR2(30),ITEM_NAME VARCHAR2(30),WO VARCHAR2(12),STRUCT VARCHAR2(12))
INSERT INTO OT_ACTUAL_ACT(ITEM_CODE,ITEM_NAME,WO,STRUCT)
VALUES ('1001','HEA100X10','300',null);
[Code]...
I am getting this
ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010
i want all the records
ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010
1003 HEA100 300
1001 HEA100X10 300

I wonder if there is some tiny technique to trace a duplicity on a block label without committing the records ( Maybe on Validate or new record instance)
I have one procedure to check duplicate but what I remember that there is something very smart provided from oracle to do that.

I have data that the user is modifying on the form and a data block that is supposed to reflect those change (summaries) So I created
TYPE VehicleInfo IS RECORD (Vehicle_Desc ctl_fleet_vehicles.Vehicle_Desc%Type,
Miles timecapture.miles%Type,
Hours TimeCapture.Equipment_hours%Type);
TYPE VehicleTab IS TABLE OF VehicleInfo
INDEX BY BINARY_INTEGER;
VehicleObj VehicleTab;
I fill this up with the correct data, but I would like to be able to use this as a table in the data block (called Vehicle_Summary) In the past I have piped tables into data blocks from the server, but I'm unsure how to use a table I created in forms in the Query Data Source Name of the data block.
