Trying to use a where clause from a table
hi,
I have a report and I need to use a where clause that is archived in a table, it is a different one depending on the row (colour=blue or number = 88..) I have tryied with ref cursor, dinamis sql, functions, packages and could not get it, any suggestion??
thanks
You may use Lexical Rerefences: "Lexical references are placeholders for text that you embed in a SELECT statement. You can use lexical references to replace the clauses appearing after SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, CONNECT BY, and START WITH....."

How do you use 3 Where Clauses in a query
Hi, i am trying to figure out how to use 3 Where Clauses in a Query where 2 of the Where Clauses uses a Sub query.
Display the OrderID of all orders that where placed after all orders placed by “Bottom-Dollar Markets”.
Order the result by OrderID in ascending order.
First WHERE clause checks for OrderDate and uses a sub query with ALL keyword.
Second WHERE clause use equals and sub query.
Third WHERE clause uses equal and company name.
This is what i have so far but i am pretty confused on how to do this.
My Code for NorthWind:
Select OrderID
From Orders o
Where o.OrderID IN (Select OrderDate From Orders Where Orders.OrderID > ALL
(Select CompanyName From Customers Where CompanyName = 'Bottom-Dollar Markets'));
The book shows how to use the ALL Keyword but not in a Sub query with Multiple Where Clauses.
Select VenderName, InvoiceNumber, InvoiceTotal
FROM Invoices JOIN Vendors ON Invoices.VendorID = Vendors.VendorID
WHERE InvoiceTotal > ALL (Select InvoiceTotal From Invoices Where VendorID = 34)
ORDER BY VendorName;>Where Orders.OrderDate
> ALL (Select
CompanyName
The comparison operator (>) requires compatible data types.
DATETIME is not compatible with VARCHAR string for comparison.
Here is your homework:
SELECT orderid
FROM orders o
WHERE o.orderdate > ALL (SELECT orderdate
FROM orders
WHERE shipvia = (SELECT Max(shipvia)
FROM orders o
INNER JOIN customers c
ON c.customerid =
o.customerid
WHERE
c.companyname = 'Bottom-Dollar Markets'));

Using a WHERE clause in APEX Tree
Hi All -
I have an hierarchical SQL query that I'm displaying as an APEX tree.
My sample app is here:
https://apex.oracle.com/pls/apex/f?p=32581:29
login: guest
pw: app_1000
workspace: leppard
I am trying to add a WHERE clause so that only nodes with the lowest level children are displayed, i.e. something like 'WHERE connect_by_isleaf = 0 OR level = 5'
The tree query with the where clause works fine in the SQL commands window, but when I add the WHERE clause to my apex tree the page no longer displays anything. Is this an issue with APEX or is there some other way to filter my results?
Thanks in advance for any suggestions,
johnConnect by occurs first, the where clause then is applied to those results, effectively cutting away in the hierarchical structure. Since apex has to build a hierarchical structure from the query it relies on the level pseudocolumn, which is butchered by applying the where clause. It's a miracle you aren't even receiving errors because I'd almost expect an incorrect json array to have been built. With no top level to start from and only level 5 or leaf nodes there is no structure to present: both apex can not put out a correct representation and not jstree either. In your query you will see your "root nodes" but it is not representable.
I'm not sure why you want to present this in a tree? Both connect_by_is_leaf and level = 5 will simply give you a list of nodes without any hierarchical structure.
The better thing to do is to use a subquery to first limit your dataset and then use that to base the tree query on, that way you don't break any of those vital columns.
Eg if you only want leaf nodes and their immediate parent you could go for something like this (quick mockup on some testdata):
with dataset as (
select node_id, parent_id
from treedata
where connect_by_isleaf = 0
connect by prior node_id = parent_id
start with parent_id = 0
dataset2 as (
select node_id, parent_id
from dataset
union all
select node_id, null parent_id
from treedata
where node_id in (select parent_id from dataset)
select level, node_id
from dataset2
connect by prior node_id = parent_id
start with parent_id is null -
Dynamic Where clause - from third party system
I have internal table A with fields I am getting from legacy system
field1
field2
field3
field4
fieldn
and i am getting a condition table (Where clause conditions) from a legacy system thru an RFC call.
and in the RFC i need to delete records from internal table A using this where clause
and where clause condition table(is 72 char length single field table) from legacy system looks like the following
( FIELD1 BETWEEN '01' AND '05' ) AND
FIELD1 NE '06'
AND ( FIELD4 EQ 'BU' )
AND ( FIELD5 BETWEEN '001' AND '009' )
How could i delete entries from internal table A using this where clause conditon table mentioned above
a®Hi a®s,
yes, thats what I thought of: Generate subroutine Pool.
I did not elaborate on the fact that dynamic where clauses are allowed only for database selections. That means that FUNCTION 'FREE_SELECTIONS_WHERE_2_RANGE' can't be used either.
But if you generate a subroutine, you can generate TYPE and DATA declarations as well. This gives you the ability to have static where condition for the DELETE itab WHERE statement.
If the type vaies during runtime, the generation may vary too.
I think you are able to do the coding for this.
On the other hand, Thomas' 'slick' proposal using a temporary database table and a subsequent SELECT ... WHERE (<dynamic where clause) may be easier to implement.
BTW: Are ther release notes on ABAP720?

PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables
Dear ALL,
My O/S is Redhatlinux 5.2 and i had Migrated my Oracle databse to 11g2. But after that while i am retrieving records through dblinks from one of my other Oracle 9.2.0.8 databse it's throwing the error : PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables.* This error i am getting in TOAD as well as SQL Developer.
Can anybody tell me how to fix this error ? Because am not able to get the records.
Also am getting another error during retrieving data from some of my tables after migrating i.e the table which having CLOB data type while am accessing to retrieve the records using select query it's throwing the error :
+(The following error has occurred:+
A query with LOB's requires OCI8 mode, but OCI7 mode is used.)
If anyone having any idea kindly share.
Thanks and Regards
BiswaHi,
Ya what u sent that is fine. But already am using one procudure which is accessing LOB data from another databse through DBlink and working fine. But there Both the databse are 9.2.0.8.
But while am executing the same procedure in oracle 11g where the Dblink accessing the data from Oracle 9i , there am getting this error.
Kindly tell if u know any resolution.
Thanks -
hi,
can we use output of a function in where clause directly ?
i.e
select node(condition1) clause from dual;
clause
occupation='SALARY'
then i want to use this output i.e clause string directly in select stmt.
select * from abc_table where clause
more strictly
select * from abc_table where (select node(condition1) clause from dual)
which is interpreted as
select * from abc_table where occupation='SALARY'
Is there any way to use functions in clause area ???
I tried CURSOR but not workd for this
Thanks in advance,
RupI cant really understand your problem
--fn1 is a function

select fn1
from dual;

Tree issue using a where clause
Tree created
select "ID" id,
"PARENT_ID" pid,
"TITLE" name,
"LINK" link,
null a1,
null a2
from apexim.TREE_NAV
I am attempting to alter this tree this way
select "ID" id,
"PARENT_ID" pid,
"TITLE" name,
"LINK" link,
null a1,
null a2
from apexim.TREE_NAV
WHERE INSTR(PAGE_ID_1,:app_page_id) > 0
This returns rows in PL/SQL however does not return tree values to the page.
this throw the error
Warning: Tree root ID "1" not found.
When I change the where clause to:
where 1=1
I get all the enitire tree as i would expect.
We are creating a report delevery application that will allow people to see specific leaves passed on authority level.
The Tree_nav table ha the url for the page to display and has the page_id_1 for the portal that launches specific content page.
So ultimatly I will include the following into the where clause
(and authority_level <= :p100_auth_level)
I have tried several things and am at wits end.rbackmann wrote:
And the page_id_1 is a field in the table (SORRY EXAMPLE BAD NAMING CONVENTIONS) that IS VARCHAR
and houses a comma seperated list of page numbers ie 28,29, 30Okay, I was wrong about the field name :(
Carefully examine the query, expecially the INSTR line. Get the values in both the column and the bind variable and make sure they are what you think they are.
The example on the other post might have failed because you were equality comparing the column value to '28' when it might have been a csv with commas unless you changed it (something worth trying).
On 4th look I may (or may not) have something. PAGE_ID_1 is a VARCHAR2, while the 28 you compared it to was a number. Its a long shot, but maybe SQL is trying to convert the csv field to a number, failing to raise an error message where you can find it, and failing for that reason. Try using '28' on the equality test.

We have tables that are interval range partitioned on a DATE column, with a partition for each day - all very standard and straight out of Oracle doc.
A 3rd party application queries the tables to find number of rows based on date range that is on the column used for the partition key.
This application uses date range specified relative to current date - i.e. for last two days would be "..startdate > SYSDATE -2 " - but partition pruning does not take place and the explain plan shows that every partition is included.
By presenting the query using the date in a variable partition pruning does table place, and query obviously performs much better.
DB is 11.2.0.3 on RHEL6, and default parameters set - i.e. nothing changed that would influence optimizer behavior to something unusual.
I can't work out why this would be so. It very easy to reproduce with simple test case below.
I'd be very interested to hear any thoughts on why it is this way and whether anything can be done to permit the partition pruning to work with a query including SYSDATE as it would be difficult to get the application code changed.
Furthermore to make a case to change the code I would need an explanation of why querying using SYSDATE is not good practice, and I don't know of any such information.
1) Create simple partitioned table
CREATETABLE part_test
(id NUMBER NOT NULL,
starttime DATE NOT NULL,
CONSTRAINT pk_part_test PRIMARY KEY (id))
PARTITION BY RANGE (starttime) INTERVAL (NUMTODSINTERVAL(1,'day')) (PARTITION p0 VALUES LESS THAN (TO_DATE('01-01-2013','DD-MM-YYYY')));
2) Populate table 1million rows spread between 10 partitions
BEGIN
FOR i IN 1..1000000
LOOP
INSERT INTO part_test (id, starttime) VALUES (i, SYSDATE - DBMS_RANDOM.value(low => 1, high => 10));
END LOOP;
END;
EXEC dbms_stats.gather_table_stats('SUPER_CONF','PART_TEST');
3) Query the Table for data from last 2 days using SYSDATE in clause
EXPLAIN PLAN FOR
SELECT count(*)
FROM part_test
WHERE starttime >= SYSDATE - 2;
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
| 0 | SELECT STATEMENT | | 1 | 8 | 7895 (1)| 00:00:01 | | |
| 1 | SORT AGGREGATE | | 1 | 8 | | | | |
| 2 | PARTITION RANGE ITERATOR| | 111K| 867K| 7895 (1)| 00:00:01 | KEY |1048575|
|* 3 | TABLE ACCESS FULL | PART_TEST | 111K| 867K| 7895 (1)| 00:00:01 | KEY |1048575|
Predicate Information (identified by operation id):
3 - filter("STARTTIME">=SYSDATE@!-2)
4) Now do the same query but with SYSDATE - 2 presented as a literal value.
This query returns the same answer but very different cost.
EXPLAIN PLAN FOR
SELECT count(*)
FROM part_test
WHERE starttime >= (to_date('23122013:0950','DDMMYYYY:HH24MI'))-2;
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
| 0 | SELECT STATEMENT | | 1 | 8 | 131 (0)| 00:00:01 | | |
| 1 | SORT AGGREGATE | | 1 | 8 | | | | |
| 2 | PARTITION RANGE ITERATOR| | 111K| 867K| 131 (0)| 00:00:01 | 356 |1048575|
|* 3 | TABLE ACCESS FULL | PART_TEST | 111K| 867K| 131 (0)| 00:00:01 | 356 |1048575|
Predicate Information (identified by operation id):
3 - filter("STARTTIME">=TO_DATE(' 2013-12-21 09:50:00', 'syyyy-mm-dd hh24:mi:ss'))
thanks in anticipation
JimAs Jonathan has already pointed out there are situations where the CBO knows that partition pruning will occur but is unable to identify those partitions at parse time. The CBO will then use a dynamic pruning which means determine the partitions to eliminate dynamically at run time. This is why you see the KEY information instead of a known partition number. This is to occur mainly when you compare a function to your partition key i.e. where partition_key = function. And SYSDATE is a function. For the other bizarre PSTOP number (1048575) see this blog

Hi All,
I am not much aware of View Links.
I am trying to extend a particular Page.
The page has an Hgrid, which looks like (Headers -> under that section data of that header -> under it attributes data of that section)
Header
Section
Attributes
There is a view link between "Headers - Section" & another between "Section - Attributes".
I want to add a filter at the Sections level. So I added a where clause to the sections VO. But the where clause is not taking any affect. So I wanted to know if this is because of the view link.
Please Help !

REP 300 error when using dynamic where clause
Hi,
I am developing a report and I need a dynamic where clause.The code I have written in the where clause is as below
function where_clauseFormula return VARCHAR2 is
begin
if :P_PO_REQD = 'No' then
return ('and pha.segment1 is null');
elsif :P_PO_REQD = 'Yes' then
return('and pha.segment1 between NVL(:p_po_num_from,1) and NVL(:p_po_num_to,99999999999999999)');
else return NULL;
end if;
end;
Now if i directly use either of the conditions in my report query it works fine.But if the parameter is No then the where clause does not work.I have also tried different statements in the if clause of the 'No' part and they work.For example the following code works when :P_PO_REQD is 'No' :
function where_clauseFormula return VARCHAR2 is
begin
if :P_PO_REQD = 'No' then
return ('and pha.segment1 between NVL(:p_po_num_from,1) and NVL(:p_po_num_to,99999999999999999)');
elsif :P_PO_REQD = 'Yes' then
return('and pha.segment1 between NVL(:p_po_num_from,1) and NVL(:p_po_num_to,99999999999999999)');
else return NULL;
end if;
end;
I don't know why this is happening.I really need a solution or a workaround urgently
Thanks
MukundYou may use Lexical Reference for the dynamic where. In After Parameter Form Trigger, code....
if :P_PO_REQD = 'No' then
:P_where := :P_where || 'and pha.segment1 is null';
elsif :P_PO_REQD = 'Yes' then
:P_where := :P_where || 'and pha.segment1 between NVL(:p_po_num_from,1) and NVL(:p_po_num_to,99999999999999999)';

END) --- <= TO_DATE(:P_DATE1,'DD-MON-YY')Hi,
Remember that a CASE expression always evaluates to a single value in one of the SQL datatypes, such as VARCHAR2, NUMBER or DATE. (There is no Boolean datatype in SQL.)
You can't say
WHERE CASE ... END;for the same reason that you can't say
WHERE 'Hello, world!';orWHERE 100;or
WHERE SYSDATE;CASE expressions are really valuable because they allow you do perform IF-THEN-ELSE logic in places where you normally can't, like the SELECT clause.
The WHERE clause is a place where you can perform IF-THEN-ELSE logic anyway, so there's rarely a need for a CASE expression in a WHERE clause. It's just as efficient and just as clear (if not more so) to put all your conditions directly in the WHERE clause, like Max demonstrated.

Asking "How can I use CASE to do this?" Is like asking "How can I use a hammer to tighten a bolt?" Perhaps there is a way, but it's likely to be contrived and ridiculous.
Here's the least ridiculous way I can think of:
