With clause usage in cursor
is it possible to use with clause in cursor declaration.
see the below simple example.
it gives error.
declare
cursor t is
(with hi as
(select * from pepole )
select distinct hi.id from hi where id =55);
begin
null;
end;
Remove the outer set of parenthesis.
declare
cursor t is
with hi as
(select * from emp )
select distinct sal from hi;
begin
null;
end;

With clause within the cursor ???
Hello gurus,
Can we have a with clause within the cursor ???
something like this ..
cursor test_cur is
WITH unpivoted_data AS
SELECT DISTINCT
f.cust_id
f.office_cd
f.type_cd
FROM refoff ro,
cutomer p,
office f
WHERE f.cust_id = p.cust_id
AND f.office_cd = ro.office_cd
AND f.type_cd IN ('ACCT', 'pay')
SELECT cust_id
, MAX (CASE WHEN type_cd = 'ACCT' THEN office_id END) AS acct_office_id
, MAX (CASE WHEN type_cd = 'pay' THEN office_id END) AS pay_office_id
FROM unpivoted_data
GROUP BY cust_id
test_cur_rec test_cur% rowtype;
Begin
for test_cur_rec in test_cur

If you get an error, post the error message.
If you get unexpected results, explain.
Whenever you have a problem, post your full Oracle version number.

Let us discussion "non recursive with clause" usage
I think there are 3 "non recursive with clause" usage.
My question is do you know more "non recursive with clause" usage ?Another option is to use it to materialize remote data on the fly. Especially in combination with the materialize hint.
I think I used this tecnique once, but can't find the proper example anymore. Very simplified it could looked like this:
with fetchData as (Select /*+materialize */ * from myremoteTable@databaselink where status = 'CURRENT')
select *
from fetchdata r
full outer join localData l on r.id = r.id
where l.status = 'CURRENT'
;From 11g onwards: use the with clause to create better column names in larger select from dual combinations.
Not sure with that results in a suitable use case.
So instead of
with orders as
(select 1 id , 173 order#, 'John' customer, 'America' region from dual union all
select 2 id , 170 order#, 'Paul' customer, 'UK' region from dual union all
select 3 id , 240 order#, 'Hans' customer, 'Europe' region from dual union all
select 4 id , 241 order#, 'Francois' customer, 'Europe' region from dual )
select * from orders;you can now write
with
orders (id, order#, customer,region) as
(select 1 , 173 , 'John' , 'America' from dual union all
select 2 , 170 , 'Paul' , 'UK' from dual union all
select 3 , 240 , 'Hans' , 'Europe' from dual union all
select 4 , 241 , 'Francois' , 'Europe' from dual )
select * from orders;THis makes it a little easier to create tase data useing some excel sheet I guess. -
'CONNECT BY PRIOR..START WITH' clause Usage
Hi All,
Could you please let me know the usage of 'connect by prior...start with' clause.
I only know that it helps for hierarchial retrival,but not aware of details.
Can someone provide the use with example for the same.
On searching on the net,I have seen numerous examples but none of them could explain it properly and everywhere the same SCOTT/TIGER schemas EMP and MGR table's example is given which is not enough explanatory.
Thanks in advance...
Aashish S.suppose u need to get all employees in a company in a hirerchical manner
ie presdent then mgrs
then employeess reporting to them
this can be done using connect by prior and start by
select empname from emp
connect by prior empno=mgrno
start with mgrno is null -
I am working with a procedure which is returning a ref-cursor to a Java Call. Inside the procedure I see a statment like
Open t_results for
with rfq_companies AS
select statement1),
rfq_hierarchies AS
select statement2),
rfq_relnhierarchies AS
select statement 3);
Can anybody explain such an usage for opening a ref cursor ('WITH' clause)?. What is the effect of using this and how Java will interpret this?The procedure is still returning a REF CURSOR, regardless of the way the SELECT statements is created. There is no effect as far as Java is concerned.

14 rows selected.As you can see, the subqueries have been moved out of the main query and put into the WITH clause, and then the main query just references those subqueries aliases.
In the above example, there's not much point in doing this, but in more complex queries, you may have a subquery that is used several times, in which case having it in the WITH clause means that that subquery is processed just once and used many times, (you can also look at the MATERIALIZE hint to help improve performance with such subqueries if necessary)
The difficulty with finding this in the documentation is because you will no doubt be trying to search for "WITH", which isn't a very good search term to be using as it's used in the english language too much for an accurate hit... so... when you learn it's called "Subquery Factoring" (because you are factoring out the subqueries from the main query), it then becomes easier to find...

OPEN CURSOR using a WITH clause in the select query
Hi,
I am using Oracle 9i. I have a requirement where I have a REFCURSOR as an OUT parameter for my procedure. I have declared the TYPE and created the procedure.
In the procedure, I am using OPEN <cursor_name> FOR <query>;
Ideally this works in most of the cases that I have tried earlier. However, in the current case I am using a WITH clause in my query to get the results.
I need help in understanding if the above mentioned syntax would not allow me to use the WITH clause in the query.What error do you get , seems to work ok for me on 10g

Hi,
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 .
I am working in a procedure where I want to manipulate the data produced by a WITH AS clause. But it is giving "PL/SQL: ORA-00942: table or view does not exist" error. A small example to illustrate my problem is given below. Here in the example am just trying to get a replaced string by using the out put of a WITH AS clause.
SET SERVEROUTPUT ON;
DECLARE
CNT INTEGER;
LETTER CHAR(1);
REPLACED_STRING VARCHAR2(10);
BEGIN
REPLACED_STRING := 'ABC';
WITH T AS
(SELECT 'ABC' VAL FROM DUAL),
TMP (LEN, SUBVAL) AS
(SELECT LENGTH(VAL) LEN,
SUBSTR(VAL, 1, INSTR(VAL, 'B', 1, 1)) SUBVAL
FROM T
UNION ALL
SELECT LENGTH(VAL)-1 LEN,
SUBSTR(VAL, 2, INSTR(VAL, 'C', 1, 1)) SUBVAL
FROM T
SELECT COUNT(*) INTO CNT FROM TMP,T ;
FOR I IN 1..CNT LOOP
SELECT SUBSTR(SUBVAL,1,1) INTO LETTER FROM TMP,T;
SELECT REPLACE(REPLACED_STRING,LETTER,'X')INTO REPLACED_STRING FROM DUAL;
DBMS_OUTPUT.PUT_LINE(REPLACED_STRING);
END LOOP;
END;
I thought of declaring a cursor which will hold the data produced by WITH clause but it did not work. Can you please let me know what are the possible options to do this.
ThanksI think, I can not use the WITH inside loop as, I want to manipulate on data resulted by WITH reading row by row from it. I have a complex procedure and I wont be able to explain that scenario here and thus i came up with a similar problem through a very simple example. I will try to explain my problem thru my example here.
The WITH in my example give an out put as :
SUBVAL
AB
BC
WITH T AS
(SELECT 'ABC' VAL FROM DUAL),
TMP (LEN, SUBVAL) AS
(SELECT LENGTH(VAL) LEN,
SUBSTR(VAL, 1, INSTR(VAL, 'B', 1, 1)) SUBVAL
FROM T
UNION ALL
SELECT LENGTH(VAL)-1 LEN,
SUBSTR(VAL, 2, INSTR(VAL, 'C', 1, 1)) SUBVAL
FROM T
SELECT subval FROM TMP,T;
and then by using this in the PLSQL block mentioned above
FOR I IN 1..CNT LOOP
SELECT SUBSTR(SUBVAL,1,1) INTO LETTER FROM TMP,T;
SELECT REPLACE(REPLACED_STRING,LETTER,'X')INTO REPLACED_STRING FROM DUAL;
DBMS_OUTPUT.PUT_LINE(REPLACED_STRING);
END LOOP;
I want to have an output like:
XBC
XXC
Please note that nature of my original problem is that I want to manipulate the data given by WITH clause in the same procedure by passing it to other functions/procs to get the desired result. So please advice me following this approach only which would be helpful.

Hi All,
I am new to PL/SQL.
I have a query where I am using WITH clause. And,it is to be used in a cursor.
so my doubt is ,where should I need to place the WITH clause ? In Declare section or BEGIN section.
Please suggest.
We tried both ways but couldn't end up with a solution.I have also searched in the forums.
Can anyone post a sample query.
Thank you.

Santhosh.Hi All,
Thanks for ur reply.
The psuedo code am using is given below.
I am using 2 cursors(CUR1OFF_1,CUR1_1) for 2 WITH clause(TEMP_Q1,TEMP_Q2) respectively.
And 2 more cursors (CUR1OFF,CUR1) for using the above (TEMP_Q1,TEMP_Q2) directly.
Its erroring out.
Can anyone please helpme out on this.

The problem is that I get unexpected ORA-00942 (table or view does not exist) errors when I try to set the SQL Query Statement property of a Query object in Reports Builder to certain SELECT statements that contain a WITH clause (aka subquery factoring clause).
For example, the following SELECT statement executes as expected in SQL*Plus...
SQL> WITH
2 SUB_QUERY AS
3 (
4 SELECT
5 1 AS X
6 FROM
7 DUAL
8 )
9 SELECT
10 INLINE_VIEW.X
11 FROM
12 (
13 SELECT
14 NESTED_INLINE_VIEW.X
15 FROM
16 (
17 SELECT
18 SUB_QUERY.X
19 FROM
20 SUB_QUERY
21 ) NESTED_INLINE_VIEW
22 ) INLINE_VIEW;
X
1...but when I try to use it as the SQL Query Statement for a Query object in Reports Builder, I get the following error:
ORA-00942: table or view does not exist
==>SUB_QUERY
My Reports Builder version is 10.1.2.0.2 version and my database version is 10.2.0.3.0.
The "real" query I have been trying to use is much more complex than this -- this is just the simplest statement I have been able to come up with that causes the problem. In fact, I have some queries that have a similar structure (a WITH clause subquery referenced inside a nested inline view, along with some other things), but strangely do not cause the problem.
I spent some time researching the problem on Google and Metalink but did not come up with any satisfactory answers. The problem sounds similar to bug 3896963, but bug 3896963 involved UNION ALL, and is supposedly fixed in my version(s).
I tried various ways of restructuring my "real" query, but with no success -- it's going to be hard to get rid of the WITH clauses. As a "wild guess", I tried various hints (MATERIALIZE, NO_PUSH_PRED, NO_MERGE), again with no success.
I ended up working around the problem by creating a database package with a function that returns a REF CURSOR based on the query, and then used that in a REF CURSOR query in Reports Builder. It might not be a very elegant workaround, but it works. I just wish I had "given up" and tried it sooner -- I might have saved myself some grief.Well, for what it's worth, I didn't end up using a REF CURSOR query after all because...
If I ran a REP file based on a REF CURSOR query against a different database, or if I ran the REP file after the database package had been dropped and re-created, it failed with the following error:
REP-8: Run time error in the PL/SQL development environment (DE).
PDE-PSD001 Could not resolve reference to <Unknown Program Unit> while loading <Unknown> <Unknown>.
REP-0008: Unexpected memory error while initializing preferences.
It seems that Reports "binds" the REP file to the timestamp of the database package that defines the REF CURSOR type in order to validate the package at run time. If the timestamp is different, running the REP file will fail with this error. This is apparently bug 1275333 and is described in Metalink Note 272936.1.
The bug reference and Metalink Note offerred the following workarounds:
1. Export the database schema that contains the package from one database and import it into the other.
In some versions, import and export preserve the timestamp, so this would avoid the problem. I didn't try this because it would not be a practical workaround in my situation (upgrade vs. new install).
2. Recompile the package and manually set the timestamp using the seemingly undocumented ALTER PACKAGE...COMPILE BODY REUSE SETTINGS TIMESTAMP... syntax.
I didn't try this because I didn't like the idea of having to: a) rely on an undocumented feature, and, b) manually keep track and maintain the timestamps of all the affected packages across several databases (e.g., development, test, and production).
3. Put the package into a Reports library or into the report itself.
This didn't work for me because Reports does not understand WITH clauses in PL/SQL. For example, with the example query in my previous post, I get an error like this:
Error 103 at line {line defining name of factored subquery}, column {first column in line defining name of factored subquery}
Encountered the symbol "SUB_QUERY" when expecting one of the following:
<a SQL statement>
4. Use an RDF file instead of a REP file.
I didn't use this workaround because I wanted to protect the design of the report by using a REP file instead of an RDF file.
So instead, I:
1. Created a database package containing a pipelined function that returned the results of the WITH clause query that Reports did not "understand".
2. Used an SQL query in my report of the form
SELECT * FROM TABLE(MY_PACKAGE.MY_PIPELINED_FUNCTION(arg1, arg2, ...))
I can drop and re-create the package and run the REP file against another database both without leading to the REP-8 error. -
Hi can any say whether we can use with caluse in cursors.
any select query having dynamic views in from clause can be used as with, and can be used in cursor tooo
