SQL & PL/SQL :: Cursor With Bind Variable And Cursor Record
Feb 25, 2011
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;
Is it possible to bind collection while opening a ref cursor. Find below the code that I am trying. My goal is to open cursor once using collection variable. Can it be done using DBMS_SQL ?
DECLARE TYPE typ_emp_rec_in IS RECORD ( deptno NUMBER, sal NUMBER [code]......
1) i have a hr.departments table that was loaded in hr schema on 1st oct 2012 with 4 columns(department_id, department_name, manager_id, location_id)
2) now I have a new schema by my name 'rahul' and I have loaded departments table but now an additional column has come into picture,ie created_date, this table got loaded on 1st-Nov-2012
3) Now going forward my columns could be dropped from the departments table (it can be a case), for example might be my departments table in my schema 'rahul' one day could comprise of only 3 columns(department_id,department_name,manager_id)
4) Now in the next step, I have managed to extract common column names(in a single line where columns are delimited using a comma) from both the tables(hr.departments and rahul.departments) which are (department_id, department_name, manager_id, location_id) using all_tab_cols table and I have written a function for it which i will be pasting below.
5) now going forward, using the above column names line with column names delimited using comma, I have used a ref cursor and assigned a query to it using the line of columns that I have extracted from the above point
6) Now I want to create a record variable which refers to my ref cursor, something like we do when we create a record variable by reffering to an explicit cursor defination that we give in the declaration block.
PS:
1) I have been out of touch with plsql for a long time so I have lost a lot of mmeory regarding plsql.
2) basically I need to compare data in hr.departments table with rahul.departments table for only columns that are common to both the tables, rest new or discarded columns information will go in one of the log tables that I have created(this is done already)
Code : =================================================================================================== create or replace procedure p_compare_data(fp_old_table_name in varchar2, fp_new_table_name in varchar2) is
i trying to pass the char varible to the cursor but it is not taking ,,, if i hardcode the values to the cursor it is taking
here is the detailed program ... why this is not taking and tell me how to pass the values through it..
declare v_name char(6) ; cursor c1(c_name char) is select name, parent,child,status from relation start with name='%' connect by prior parent=child union
i am creating an apex page where i have 2 regions. From the Top region stores all fields entered into the bottom region Text fields like first name and last name and address fields are in region 2(bottom).After region 2, i have a add person button.
Once i click add person, that person will get into top i.e region 1.
Now, Region 1 got person1 first name ,last name person2, first name,last name etc..
I am not able to display like p1_first_name,p1_laast_name as the list is not stable..it is growing and not showing the person who already got saved..I can retrieve them from DB using a cursor..But from cursor vairable how to get into page vairable..
While reading data from collection variable using ref cursor . I am getting the below two errors.
PLS-00382:Expression is of wrong type ORA-22905 Cannot access rows from a non-nested table item.
CREATE OR REPLACE PACKAGE APPS_GLOBAL.GIIOMEGAORDERLIST AS TYPE BU_LIST_TYPE IS TABLE OF VARCHAR(50); TYPE OFFER_DETAIL IS RECORD ( GII_BU VARCHAR(50), GII_OFFER NUMBER, [code]........
I've got a task to star out account numbers in a free text field. The account numbers can be in a few different formats and there are a number of tables. The formats could increase or change as could the tables. For that purpose I want to use a couple of tables; one to store the formats and one to store the tablenames. The tablenames work fine, but I'm having problem with the formats.
INSERT INTO account_format VALUES (1, '''[0-9]{5}[A-Z]{1}-[0-9]{5}''', '''[0-9]{5}[A-Z]{1}-[0-9]{5}'',''****-****-****-****''', 'Y');
The idea is to bring back the format and use it in REGEXP_INSTR (or a similar REGEXP) to ascertain if the field contains the account number. The code I have been using looks a bit like this:-
CURSOR m_format_cur IS SELECT acc.acc_format FROM account_format acc; m_format_rec m_format_cur%ROWTYPE; IF REGEXP_INSTR (m_narrative, m_format_rec.acc_format) > 0 THEN .... END IF;
I have tried several different ways to get this to work e.g. hardcoding the format and declaring a variable with the format, which both work. Whenever I try to use the value retrieved from the database field it never works. Why should a variable from a cursor not work?
I need to run a query that runs a stored procedure. The stored procedure takes a cursor of record ids as a parameter. I've been making the cursor like this, if there was a smarter way. I can't change the stored procedure, so this is the only thing I have control over.
CURSOR id_cur IS SELECT id FROM table t WHERE t.id IN ( id1, id2, ... id500
);It just seems kind of strange to select only ids from records when the list of ids is given.
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.
when I updated a record in my form check my screenshot: and clicked save button the result was:
as you can see in the message at the bottom, it has 18 records. And since my original data(subjects) are just 9. And also the grades that I input didn't display all.
This is my code in when-new-block-instance trigger: DECLARE CURSOR studgrade_cur IS SELECT e.student_id, s.subject_code --, g.grade
SQL> show user USER is "ANDREY" SQL> SQL> SQL> SQL> --create the table:
[code]...
I insert rows into it:
SQL> --fill it with data: SQL> SQL> insert into a(key1 , key2) values (1 , 1); 1 row created. SQL> insert into a(key1 , key2) values (1 , 5);
[code]...
i want to perform a logic by which:for every distinct value of key1 - values of key2 will be checked in all records holding that particular key1 value, and update the key3 field to 'inactive' where the key2 value for that particular key1 is the highest in number.
i've found out that i could do it by an SQL statement:
update a set key3 = 'inactive' where key2 = ( select max(key2) from a a2 where a2.key1=a.key1 );
however I wanted to use the cursor to "load" the max key2 values FOR EACH distinct key1 value exists in the table,and do the same thing as the update statement above WITH A CURSOR,So tried and wrote the following:
SQL> create or replace procedure proc1 2 IS 3 4 5 var1 a.key1%type;
[code]...
unfortunately, it works only for one row, and i don't understand what's wrong, I executed, and checked what has changed:
SQL> exec proc1; PL/SQL procedure successfully completed. SQL> select * from a; KEY1 KEY2 KEY3 ---------- ---------- ---------- 1 1 active 1 5 incative 2 24 active 2 21 active
In my form line level block contains 100 records.i will check the check box for line number 96 and 97. Then i will press save(I have written some logic here) button it will generate one number for selected check boxes. After generating this number cursor(control) should be on same line number 96 or 97.
I have Two cursor record block..which is attached in form..
My TASK IS
In my first Block, When DBCR Column = 'D' Then in backend this column value should be save as a '1' WHEN DBCR Column = 'C' Then Then in backend this column value should be save as a '2'
My Both Field is on Data Block...
In Property palette of this field can we write any decode condition..so it reflects directly on database.
i m using oracle 10g 10.2.0.2 version.i create a form and using check box on this form.when i click this check box then loop is using behind it.and current cursor is going to last record
i want if i click 4 record then cursor is still showing on 4 record mean i click which record after using loopmy current cursor is showing on that particular record
how to write below query in pl/sql cursor. The help table has two associated tables, help_txt and help_id, which will have strings of data concatenated into one sales contact record. There are multiple lines of text per comment and multiple lines of resolution text at 40 characters per line. The key to the help_text table (id, date,seqno) is the main key to the help_txt table and help_id t table with a sequence added to each table
The formatted string will contain some text and variables with the comment lines (1-10 or more) concatenated first, followed by the resolution lines (1-10 or more). There will be multiple comment and multiple resolution lines. The Cust_Cmnt_Txt lines and the Resolved_Desc lines should be concatenated and formatted in the following string (% marks the variable string) :
'help taken ' %help.Taken_Dte 'received from the following source: ' %help.id. 'Remark Text: ' %help_text (where help_txt_Seq = 1) %help_text (where help_text_seq = 2-10 or more) 'Resolution: ' %help_id_Res_Txt.Resolved_Desc (where help_ID_Txt_Seq = 1) %help_ID_Res_Txt.Resolved_Desc (where help_id_Txt_Seq = 2-10 or more)
I have the below cursor 1 which is working already.For my requirement i want to use bind variable like second cursor.But its telling Bind Variable "p_col_list" is NOT DECLARED.
How to use bind variable Here.
Cursor1: DECLARE emp_cv sys_refcursor; iid NUMBER := 1; i_sql varchar2(100); p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd'; BEGIN i_sql := 'select '''||REPLACE(p_col_list, ',', ''',''')||''' from dual '||CHR(10) ; dbms_output.put_line(i_sql); OPEN emp_cv FOR i_sql ; END;
Cursor2: DECLARE emp_cv sys_refcursor; iid NUMBER := 1; i_sql varchar2(100); p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd'; BEGIN i_sql := 'select '''||REPLACE(:p_col_list, ',', ''',''')||''' from dual '||CHR(10) ; dbms_output.put_line(i_sql); OPEN emp_cv FOR i_sql using p_col_list; END;
I am facing the same problem: SP2-0552: Bind variable "OLD" not declared. When my script create_trigger.sql is executed,there is no error but when i execute it inside a pl/sql block it get above error...In the trigger we are using if conditions
if(:new.sumthing=1)and (:old.sumthing=0)the do this..
Identical statements from this link : Parsing in Oracle — DatabaseJournal.com d. The bind variable types of the new statement should be of same type as the identified matching statement. i am getting confuse here .. when parsing occurs some links saying about bind variable.but official document never said about bind variables.
PLS-00049 BAD BIND VAIRABLE 'OLD.REMARKS' When i create or replace the following trigger
CREATE OR REPLACE TRIGGER T_TASKHISTORY AFTER UPDATE ON S_TASK FOR EACH ROW DECLARE BEGIN INSERT INTO S_TASKHIS (HIS_DATE,SUBJECT,DESP, SCHEDULED_DATE, SCHE_TIME ,USER_MOB_NO
