Today we faced one strange issue Varchar doesnot print the zero front of number
eg
SQL> select agent_code from table_name where AGENT_CODE = 0061;
AGENT_CODE
----------
61
61
where in my database agent_code columns as value 0061 and 061 for both it shows same value.
I see you can build an address object consisting of street name and number, city and so on, and use this in CREATE TABLE, so all tables use the same fields for addresses. And moreover you can add check functions to prevent street numbers to be negative for instance in the constructor. You can even use inheritance. I like that.
However, all teaching on this subject I found on the Internet starts with structs (points consisting of x and y, persons consisting of name and address, etc.). Then they go to inheritance and show how to build an employee who is just a person plus an employee number. They never start with simple types.
What I would like to do would be rather to start with basic types such as number or varchar2 and inherit from them. An EAN is a VARCHAR2 holding only digits where the last digit is a check sum that must be matched. An item number may be a VARCHAR2 matching 'NNN-AAAA'. A simple string may be a VARCHAR2 where no functional characters such as carriage return, etc. occur.
I would then write my create table statement thus:
CREATE TABLE item (itemno T_ITEMNO, ean T_EAN, itemname T_SIMPLESTRING); and inserts like INSERT INTO item values('123--BCD', '1234567890abc', 'toy') would fail with exceptions like 'item numbers must be formatted NNN-AAAA' or '1234567890abc is not a valid EAN'.
However this seems not possible:
create or replace type T_EAN under varchar2
(
constructor function T_EAN(p_string in varchar2) return self as result
);
fails with "PLS-00580: supertype must be an object type".
Rather than creating completely new types, I would start with extending existing types, but this seems not possible. Is that really impossible or am I using the wrong approach?
I have procedure that is used by trigger but I define it as Varchar2 it's result show number.
change my PLSQL to use as varchar,
If trigger fired, the procedure make this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM = 01071234151;
but I want this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM ='01071234151';
because CUST_NUM is VARCHAR2(12)
so it can use index appropriately.
how can I change my PLSQL this sentence,
v_sel_sql1 := 'select CB_SMS_FLAG, CB_SMS_DT from ' || pTBL_NM ||' where CUST_NUM = ' || pCUST_NUM;
Here my code
CREATE OR REPLACE PROCEDURE ORAASFS.P_TM_SFS_CB_SMS_CNT_upd_104(
gKIND VARCHAR2,
pCUST_NUM VARCHAR2,
pSMS_CNT NUMBER,
pSMS_CLC VARCHAR2,
pRD_FLAG VARCHAR2,

Have table with two columns with datatypes as number and varchar and the values in A column like 1,2,3 AND B column values like a,b,c. Now need to display data in a single column as 1,a,2,b,3,c.
View 4 Replies View RelatedI would like to know if using varchar parameter in sql queries with number column can result in performance degrade.
Ex: Procedure testa ( myparam varchar) is
begin
select col1 into var1 from table where colno = myparam;
end;
Here col no is a number column and myparam is varchar. I feel its better to change the parameter to number.
I want to print two record of emp table in same line number in tabular format report.
For example if i have emp table and I want to print empno,ename,sal columm only,In tabular format report, Two record should print per line. so If emp table have 14 record report should be printed on 7 rows.
so the output in print preview should be like this
EMPNO ENAME SAL EMPNO ENAME SAL

I have set up a label which interacts with our LIMS system. I have set up variables on this label which pull in attribute values from the available tokens. When the attribute value is null, the label is automatically inserting 'N/V' onto the label.
I would prefer for the variable to appear as a blank field on the label when the attribute value is null in the LIMS. can't find anything in the user's manual. Perhaps there is some setting where you can define what to display for null values. I can't seem to find any information on this.
I am trying to login through front end application. I am getting the error login failed.
I tried to login from back end using same USERID and password. In the login page it's asking for EDUSERID and password. I tried to connect from backend to the database using same EDUSERID and password and it's working fine. But why from front end application I am unable to login.
I am hoping to test the behavior of a complex web application that is backended by an Oracle 9i database, against an upgrade to 11g database.
The current setup runs basically on 4 Solaris servers, The database, the Oracle Application Server (version 10 something) (2 instances running on the node/server with no OHS), an install of OAS/OHS as a load balancer box, and the non-OHS Apache2 web server front. Apache takes the request from the web and reverse-proxies it to the OHS load balancer, which sends it to one of the two instances on the single application server. This is a java application and uses an Oracle 9i database to feed it.
I have had enough server resources to clone the database, the app server and the web server, and upgrade the database to 11g. I am unable to setup an OHS load balancer box.
So my question is, how do I configure the Apache WS to communicate directly with the OC4J container(s). I can shut down an instance if that simplifies things. Or, if I had to I could look into standing up OHS in the OAS install, as that seems to be where all the info is focused on the technical info sites (Oracle and others), but since these are clones and I think it might be easier to just short circuit around the now missing load balancer box. Many configurations have already been done to be sure the 'clone' identifications are self-referencing, like the hosts file, etc. to point to resources in the Cloned environment.
I am new to oracle 10g. I have a strange problem which i never used to face it while using oracle 8i.
Out of around 120 forms , there is 2 forms in which all the data entry is being done. any changes made to the coding / text in these fmb is not getting effected when i run the form through front end.The front end is developer 2000 .
Where as changes made to the other fmb is working perfectly fine. Is there any deployment issues which needs to be taken care off in oracle 10g.
I am trying to write which will return cursors to front end program.The logic which I got stuck is while exiting the procedure.I am having some cursors in teh procedures which are read by the front end script.I have one condition which when satisfied I have to exit from the procedure.But the constraint I am facing is if I exit at that logic, oracle closes all the cursor and front end script is not able to read teh cursor and hence throws an error.Is there any way to exit the procedure without closing the REF cursors.
View 3 Replies View RelatedI am trying to generate a software that used VB as the front end and Oracle 10G as the back end. I have noticed that the date format is VB is : m/dd/yyyy whereas the date format in oracle is dd-mm-yyyy. Whenever i try to insert a tuple with either of the date formats, the program halts running and after a long time , i get a message saying a deadlock was encountered. I have never had any formal introduction to either of the two tools

Users use front end (called ESS Console) and when they try to open one of those tables they wait very long (really bad performance). Sometimes the GUI even hanging without displaying results.
Does Partitioned Tables feature works for better performance?
I have one command compare varchar type with date type by Pl/SQL.
date_entry gave values:" 2012/01/06 22:28:24",
now i want to convert it to date and compare with sysdate.

how to create sequence to varchar and how see that sequence
View 2 Replies View RelatedI've a large table on which I applying aggregate and group by functions to the the results.
Here are two of the columns in my table:
Name ==== Score
John ==== 200*
Zohaib ==== 299
Ali ==== 0*
John ==== 200
Maria ==== 150*
Ali ==== 0
Maria ==== absent
John ==== absent
Here astrick (*) means with distinction....
The "score" column is a varchar column I want to run a query on this table to show the highest score for each student and the output should be like this:
Name ==== Score
Zohaib ==== 299
John ==== 200*
Maria ==== 150*
Ali ==== 0*
Important note:
1. if there is a tie between two highest scores like for a student, incase of john 200 was made twice, but the score with asterick (*) will be the "maximum" becuase it is with distinction so the output should also show the the highest score with asterick.
2. the output should show the the 2nd column (score) in desc order of highest score by each student...again incase of a tie, the one with astrick will come first in the result..
I know with just mere numbers, that is pretty easy but in this case it is a varchar column and also i need the astrick along with the highest score.
I want the simplest and shortest query if possible to achieve this result
I hope I've been able to clearly explain my requirment. I am using 10G.
What is the exact difference between varchar and varchar2?
As i know only the length is the one difference.Apart from this length,what are all the differences?
I have a varchar field in a table. When I store the following string, some undefined character is storing.
String to be stored: Test String
String actually stored: Test ¿ string
Please note that here '' is not Hyphen. It is a special character that msword has. when you copy this and paste in a word document you find the difference.
I have listed the character set for CHAR and NCHAR from NLS_DATABASE_PARAMETERS
NLS_CHARACTERSET - WE8ISO8859P1
NLS_NCHAR_CHARACTERSET - AL16UTF16
When you create a backup in SQL Server, whether the backup is on disk or on tape, SQL Server writes the letters TAPE to the first four bytes of the backup. Does Oracle write any specify value to the front of every backup, and if so, what are the first four bytes?
View 2 Replies View RelatedThe below table and functions are examples, but issue is like this.
i have one issue while forming below sql , Application will form this query at run time wih required inputs
it is failing because the application will not support the clob datatype.
Table : T_E (similar to EMP table structure)
This table has data similar to emp but bulk data around 10k records.
Query formed
select empno,ename, get_employees(deptno)
from t_e;
This sql query this is failing when function return varchar2 string more than 4000 size.Because in sql query size should not exceed 4000 for varchar2 data type , function return size can be upto 20000
Function which
CREATE OR REPLACE FUNCTION get_employees (p_deptno in emp.deptno%TYPE)
RETURN varchar2
IS
l_text varchar2(32767) := NULL;
BEGIN
FOR cur_rec IN (SELECT ename FROM t_e WHERE deptno = p_deptno) LOOP
l_text := l_text || ',' || cur_rec.ename;
END LOOP;
RETURN LTRIM(l_text, ',');
END;
I can try this with clob but application doesn't support that..so i tried with using clob in above function , after that while returning to application i want to conver the clob to char and return the entire string
select empno,ename, to_char(substring(get_employees(deptno),1,4000)) -- first 4000 characters
, to_char(substring(get_employees(deptno),4000,8000)) -- next 4000 characters
from t_e;
But this is failing how to return the entire string in above sql
How to get max and min value from a varchar2 datatype column?
CREATE TABLE TEST
(
WEIGHT VARCHAR2(20)
);
INSERT INTO TEST VALUES('100');
INSERT INTO TEST VALUES('120');
INSERT INTO TEST VALUES('113');
INSERT INTO TEST VALUES('145');
INSERT INTO TEST VALUES('204');
INSERT INTO TEST VALUES('130');
I've to find the max and min weight from this data.
We have server oracle 11 , running on UNIX . we have table with a lot of columns - varchar2(4000)
My question
when data comes from server to client? what actually comes for column varchar2(4000) ?
for example value of columns 'abc'
does it mean that from server to client will be sent buffer with size 3 char ?
or
it will be sent buffer 4000 characters and one more value shows how big is variable inside buffer ( for this case it will be 3 )
I need to separate 1 field into 2 fields. The source is varchar2 and is like:
[VOUCHER]
CGJ0000617
CG0001442
CGJ0001444
CMOV0000200
CXAR00000001
CXAR00000002
Result should seperate numeric value from characters so that the result would be:
[VOUCHER_char] [VOUCHER_num]
CGJ 0000617
CG 0001442
CGJ 0001444
CMOV 0000200
CXAR 00000001
CXAR 00000002
I need one or two SQL statement.
Why does oracle not allow the following query
select to_clob(1) from dual
union
select wm_concat(sysdate) from dual;
wm_concat returns a clob. To make both queries in the union have the same type columns i convert the column in the first query to a clob but Oracle gives me an [1]: ORA-00932: inconsistent datatypes: expected - got CLOB error even though both are returning a clob value.
Each of the queries work individually and both return a clob value.
i have a table COLOR having alphanumeric fields i.e Color Description & Color Ref. i want to copy the values from Color Description to Color Ref.
