i want to update the values based on with clause so i used like above.but it is time consuming so i planned to use cursor . is it effective or any other methods avail for the above. How to write cursor and use for the above ?
set serveroutput on
declare
type curs_type is ref cursor;
rec employees%ROWTYPE;
curs curs_type;
[code]...
It gives the error "identifier in CURRENT OF clause is not a cursor name" even though the identifier "curs" is a cursor name
I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.
Is it possible to:
-define a cursor with bind variables
-get a cursor record from these cursor
-and pass the bind variable in the OPEN clause
Did'nt succeed as shown in the example.
SET SERVEROUTPUT ON SIZE 900000;
DECLARE
--works fine
CURSOR c1 IS SELECT * FROM USER_TABLES WHERE rownum<3;
--doesn't work
--CURSOR c1 IS SELECT * FROM USER_TABLES WHERE rownum<:1;
crec c1%rowtype;
BEGIN
--works fine
OPEN c1;
--isn't possible ?
--OPEN c1 USING 3;

can we use something like this
"select ... order by emp from emp"
what is to be done? so that this qurey runs. no co-related subquery to be used.
just looking around to use the new feature available in oracle 11g to convert the dbms_sql numeric cursor to reference cursor, how to do it?
parse and execute the sql string first with dbms_sql and then convert it to ref cursor?
I want to return ref cursor based on explicit cursors

Note:- I got only this that this query is alternative of self join and it is giving manager name along with mgr id for each employee but when it gives output i couldn't able to understand how to identify who is manager of whom. Tell and explain with clause in oracle , i only know it is alternative of inline view but i want to know how does it work and how to use 'WITH' in oracle query if possible.
I have a scenario where in report table I need to get
IF FLAG='Y' AND LOC=118443 THEN STATE='FIN'
IF FLAG='Y' AND LOC!=118443 THEN STATE SHOULD BE ('COMP','PART')
IF FLAG='N' IT SHOULD INCLUDE ALL STATES.
I tried using decode in WHERE CLAUSE , but not successful.
Create Table Report(Id Number,Loc Number,Flag Varchar2(3),State Varchar2(20));
table REPORT created.
Insert Into Report Values(1,1,'Y','COMP');
1 rows inserted.
Insert Into Report Values(2,118443,'Y','FIN');

But this gives an error...If the decode gives a "single"...the statement is working fine...but If the decode gives a "range"...the above statement gives an error saying "missing keyword"..Does the above code when mapped to "Range"...is it not producing "and" like " value between 100 and 1000"
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.
View 2 Replies View RelatedYou think i can do a from clause with conditions ??
The reason is that i need to retrieve fields from different schemas depending on a column in a common table
let s say the column CRITERIA_COL is in table Common
If COMMON.CRITERIA_COL has value 1 then the select query should fetch results from the schema : SCHEMA1.MY_TABLE
If COMMON.CRITERIA_COL has value 2 then the select query should fetch results from the schema : SCHEMA2.MY_TABLE
If COMMON.CRITERIA_COL has value 3 then the select query should fetch results from the schema : SCHEMA3.MY_TABLE
Something like this:
Select my_Col1, my_Col2 from
(case COMMON.CRITERIA
when '1' then SCHEMA1.MY_TABLE
when '2' then SCHEMA2.MY_TABLE
when '3' then SCHEMA3.MY_TABLE
)
but that is not working .By the way my query is not just that, it s a more complicated query, that s just the portion I am having trouble with .
I am not strong in SQL but can write easy SQL for data extraction but seem to not understand how to correctly use sysdate in a where clause.
Case: I have to create an alert that will email my IT dept once a person is terminated in Oracle HR. The alert will only run once a day with all terminations specified in the alert. Setting up the alert is not the issue, but rather the SQL code I want to use.
The alert will run everyday at CoB 17:30. Now, in my query, how do i specify that the results should be only for the current day? The problem however, is that I also retrieve Person Type which should show as Ex-Employee, but this is only shown the day after the actual termination has been done, because the employee is still active on the date of termination.
Is there a way to have a variable in the FROM clause or another way to have the table name as a variable? I'm trying to not repeat the same query three times with only the table name being different.

I mean see two different outputs.first output records twice displayed ... Yes i agree that is Inner join.second output records not displayed twice... common records only displayed once ,in x and y.
I think should n't use a table name or alias when referencing columns used in a USING clause... am i right ????
I want to know both are inner joins .how Oracle is determined both outputs ?
SELECT sno,mid,mname
FROM manage_date
WHERE mname IN

IF I use this query directly in DB it's working fine. But when this query is calling in .net using parameter as below it's not giving any records for more than one value. IN (:p_mname)
If I pass one name 'KIRAN-KUMAR' from .net It's working.
If I pass multiple names from .net query not returning any records.
I have to create a WHERE clause like :
SELECT * FROM wc_claims WHERE part_nbr in l_part_nbr ;
I have three tables:
table A has - user_id, supplier
table B has - supplier, part_nbr
table C , wc_claims, has part_nbr and 78 other columns.
what i need to do is when user logs in with his user_id, he should see only that info from table C, corresponding to his supplier, and the part_nbr.
SELECT supplier from table_A WHERE user_id = 'abc' ;
supp_abc
SELECT distinct part_nbr from table_B WHERE supplier = 'supp_abc' ;
partA, partB, partC,........partZZ
SELECT * FROM wc_claims WHERE part_nbr in (partA, partB, partC,........partZZ );
I have created a function :
create or replace Function wcl_partnbr ( p_supp IN varchar2 )
RETURN CLOB
IS
[Code].....
so that I can use that in the WHERE clause, because one supplier can have thousands of parts...so it works fine, if there are 200 part numbers for one supplier, but above that.. it doesnt.
I having below table :

If user has given value for cnm column then ref cursor should be :

But then i need to insert 100000 rows more using the stored procedure and without removing the 400000 rows stored before. I think i need to use the commit clause, but i dont know where.
