PL/SQL Loop Types - Variables Incrementing Together
Nov 8, 2012
set server output on;
DECLARE
num number(1) :=1;
num2 number(1) := 1;
BEGIN
WHILE num < 5 LOOP
[code]...........
the output for this loop is:
1+1=2
2+2=4
3+3=6
4+4=8
this is what I wanted. Both variables are incrementing together. However, when I try to use a FOR loop to do the same thing:
set serveroutput on;
DECLARE
num number(1) :=1;
num2 number(1) := 1;
BEGIN
FOR i in 1..4 LOOP
[code].......
I get the result:
1+1=2
1+2=3
1+3=4
1+4=5
2+5=7
2+6=8
2+7=9
2+8=10
3+9=12
DECLARE
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 8
I understand the output means the inner loop is running its course before the outer loop is started and then continuing on to exceed its limit, but I don't understand why this is or how to make it so I get the same results as the WHILE loops.
PROCEDURE CALCULATE_CASH_REBAL( P_Account_id IN VARCHAR2, P_Txn_Ccy IN VARCHAR2, P_Allocation IN VARCHAR2, l_lty_id IN VARCHAR2 ) IS l_balance_fmt NUMBER := 0; BEGIN [code]....
it should be updating l_balance_fmt field for all the records in the loop. my question is when it loops to the next cash txn record, will it take the previous value of l_balance_fmt ? it should start again and take 0 as the balance_fmt and add to that..
The idea of the program below is to create a sql "module" (just a .sql file) that will loop and ask for a user id until the user enters the correct one. Here is the code I have thusfar:
set serveroutput on; accept username prompt 'Enter user name here: '; accept password prompt 'Enter password here: ';
declare usernameCONFIRM VARCHAR(30); passwordCONFIRM VARCHAR(30); begin select USERID into usernameCONFIRM from GAMEUSER where USERID = '&username';
[code]...
The main problem I'm seeing is that the two variables I ask for (username and password) aren't clearing out.
My problem, I have the query which works correctly. However as you can see there is always a sequence number in the end of variables and I am not sure the total number of cases, so I have to create a loop for the same query.
I am doing the same things on BREINV1 BREINV2 BREINV3 BREINV4... AND BRENUMINV1 BRENUMINV2... so the sequence should add a number in the end of variables...
Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=p1; END; ------------ Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS v1 varchar2(100):=p1; BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=v1; END;
CREATE OR REPLACE PROCEDURE IND_MONITOR(P_tab VARCHAR2) is type ind_table is table of varchar2(20); p_ind ind_table; v_sql varchar2(2000); begin select index_name bulk collect into P_Ind from user_indexes where table_name=upper(P_tab); for i in 1..p_ind.count loop v_sql :='alter index '||p_ind(i)|| ' monitoring usage' execute immediate v_sql using p_ind(i); end loop; end;
I have two Oracle instances, both are 10.2.0.3..Executing the following results in two different results:
select N'Test" "result" from dual;
On one the output is: resu ---- Test
and on the other the output is
result ---------------- Test
This seems to suggest that one is returning "Test" as a char(16) and the other as a varchar2 or nvarchar2. In both cases, NLS_CHARACTERSET is WE8ISO8859P1 and NLS_NCHAR_CHARACTERSET is AL16UTF16.
Not being an Oracle DBA, I am not sure where to look.
I read about many indexes as B tree index, function based index,Bitmap Index etc.how many types of Index are there in Oracle and what are they? wat are the categories and sub category? when to use what?
Types of oracle index in detail. consider this situation, if a select query without any where clause takes much time to get data,then we will create index for that table.
Now again run the same select query. this time, whether the query takes much time again or will it work fast? whether the index is used for a select query execution or not?
How we can confirm that whether the oracle using the index normally?
I have four employee types such as 'C' for consultants, 'S' for staffs, 'W' for workers ,, ('E','S','W') for all types of employees. i have write four queries for showing four types of employees. can it is possible in a single query.
I have written this in oracle forms . I have taken a list item for workers i have taken 'W' , for staffs i have taken 'S' , for consultants i have taken 'C' and for all i have taken 'A'. my column name is emp_type in( :block.list_item ) but it is not taking the value from the list item when the value is emp_type in('C') etc etc..
like this for workers ,staffs . when it is 'A' it will take emp_type in ('E','S','W')

SQL> with t 2 as 3 ( 4 select 1 id, 12 compid, 1 rel_type, null enddt from dual union all 5 select 1, 13, 1, to_date('31.12.1993','dd.mm.yyyy') from dual union all 6 select 1, 14, 1, to_date('12.06.1996','dd.mm.yyyy') from dual union all 7 select 1, 15, 1, to_date('23.04.2003','dd.mm.yyyy') from dual union all [code].......
I want to find the the latest compid for individual types 1 and 2 only within a list of ids. Latest compid is defined as the compid associated with the latest end date (null is treated as the latest end date).
So in the above example for rel_type = 1, compid : 12 is latest, for rel_type : 2, compid : 6 is latest.
Datatype for the tables are :
Id : Number compid : Number Rel_Type : Number enddt : Date
how to display REFS from within a REF. I've not used my exact code here as its quite a big file so i've made a similar scenario to get me point across. Here is the code first:
1 CREATE OR REPLACE TYPE object1 AS OBJECT ( 2 object_id NUMBER(5), 3 object_name varchar2(10), 4 object_added DATE); 5 / 6 CREATE TABLE object1_tab OF object1 (object_id PRIMARY KEY); 7 / 8 INSERT INTO object1_tab 9 VALUES (1,'Daniel',sysdate); 10 / 11 show errors; 12 / 13 CREATE OR REPLACE TYPE object2 AS OBJECT ( 14 object_id NUMBER(5), 15 object_job varchar2(10), 16 object1_ref REF object1 ); 17 / 18 CREATE TABLE object2_tab OF object2(object_id PRIMARY KEY); 19 / 20 INSERT INTO object2_tab 21 VALUES (1,'Developer',(SELECT REF(p) FROM object1_tab P 22 WHERE VALUE(p).object_id = &object_id)); 23 / 24 select DEREF(object1_ref) 25 FROM object2_tab; 26 / 27 CREATE OR REPLACE TYPE object3 AS OBJECT ( 28 object_id NUMBER(5), 29 object_location VARCHAR2(20), 30 object2_ref REF object2); 31 / 32 CREATE TABLE object3_tab OF object3 (object_id PRIMARY KEY); 33 / 34 INSERT INTO object3_tab 35 VALUES (1,'New York',(SELECT REF(p) FROM object2_tab P 36 WHERE VALUE(p).object_id = &object_id)); 37 / 38 show errors; 39 / 40 select object_id,object_location,DEREF(object2_ref) 41 FROM object3_tab; 42 /
As yot can see in the code each object refernces from the previous. When I view the DEREF in the third table (object3_tab) i get the following output:
OBJECT_ID OBJECT_LOCATION DEREF(OBJECT2_REF) --------- -------------------- ---------------------------------- 1 New York [SANTA.OBJECT2]
need to use Extend() in nested tables in Oracle? What could be the problem if I do not use this method in my code?
I have a nested collection type (TABLE OF VARCHAR2(32)) declared in my package. My stored procedure takes the TABLE type as input and inserts that data into a database table. I see that my code works fine without using EXTEND method.
I'm trying to determine why subtype creation is not working in 11G R2 XE, while it works in 11G R2 EE.
Environment is XE 11.2.0.2 on Windows 7 X64 (yes, not supported but I don't have anywhere else to try this).
Here is a test case, using the SYSTEM account as that is what the developers use (yes, terrible practice) :
--type -- this works, creates the type CREATE OR REPLACE TYPE [schema].prod_type AS OBJECT ( pid INT, pprice NUMBER, MEMBER PROCEDURE display(pid IN NUMBER)) NOT INSTANTIABLE NOT FINAL;
[code]....
I've tried adding the schema name after UNDER, e.g. UNDER [schema].prod_type with the same result.
How to eliminate duplicates from record types?Below code errors out with "Wrong number of arguments in call to MULTISET...."
error. DeclareTYPE ln_x_tab IS RECORD(x1 number ,x2 VARCHAR2(4000) ,x3 VARCHAR2(4000) ,x4 VARCHAR2(4000) ,x5 VARCHAR2(4000)); TYPE ln_x_type IS TABLE OF ln_x_tab INDEX BY BINARY_INTEGER; ln_x1 ln_x_type; ln_dist_x1 ln_x_type; gc_stmt varchar2(4000); Begin gc_stmt := ' SELECT x1, x2, x3, x4, x5 FROM table WHERE dynamic_conditions; EXECUTE IMMEDIATE gc_stmt BULK COLLECT INTO ln_x1; ln_dist_x1:= ln_x1 MULTISET UNION DISTINCT ln_x1; End;
I need ln_dist_x1 to have distinct records from table.
I'm trying to call a custom made PL/SQL function in a SQL query. I want to supply the values of the parameters during the query. I can call the function if I "hard code" the parameter values, but when I try to supply them I get the ORA-06553 error.
This call works:
select pkg_tm_import_util.wb_screen_hr_refresh_func('','','','','','','','','','','','') from dual
However, this does not, but should be the same as the call that works:

I am migrating sybase to oracle database. A Java developer needs money datatypes.I said to them, please change the cast(<value> as number(19,4) in java code side. but they are not accepted because money data type is used most of the places.
select cast(0 as money) from bank_trans; this sql statements present in java code. I need to create user defined type is equivalent to money datatype.
My steps
I have create user defined data types
create or replace type money as object(money as numbeer(19,4)
select cast(0 as money) from dual;
it shows inconsistent datatypes error.
create or replace type money is table of numbeer(19,4);

My questions are:
1. I have created an object table person_obj of parent type. I have not created object tables of salesperson_typ and customer_typ and want to store data related to both in person_obj. What is the difference between storing data in an object table of parent type and object table of subtypes? In which case should I consider storing data of all subtypes in an object table of parent type instead of object tables of individual subtypes?
2. Second question is regarding validating the column values before the creation of object instance. Suppose before creating an instance of salesperson_typ, I want to check if salary is NOT NULL and greater than 0. I guess constructor is the only option to achieve this but how full-proof it is if constructors are used for this purpose? Is there any other alternate way?
Question 1: What is the no of column limits in a single table? Is it same for all type of tables. Question 2: How to estimate the size for a table in advance with "undo generation amount, index size, redo log size"? Question 3: What is the real time scenario for creating a table on another schema? Question 4:I read the below line in a document, but I'm not able to understand it
"we can't move types and extent tables to a different schema when the original data still exists in the database"?
