Explain me the following behavior of DECODE?
SQL> select decode(null,null,'Matched','Not Matched') from dual;
DECODE(
-------
Matched
As expected, output should be 'Not Matched' instead of 'Matched'
I would like to use the below decode in DBMS_OUTPUT in place of cur_rec.data_type. Could I know how can I achieve this.
The DBMS_OUTPUT is inside a loop and output is shown below as an example.
NOT NULL -- EMP_ID NUMBER
,NOT NULL -- EMP_NAME NUMBER
,NOT NULL -- HIRE_DT DATE
,NOT NULL -- SALARY NUMBER
DBMS_OUTPUT STMT:
Dbms_Output.Put_Line(nullable ||CHR(9)||CHR(9)||' -- ' ||upper(cur_rec.column_name)||CHR(9)||CHR(9)||cur_rec.data_type);
STMT to use in place of cur_rec.data_type:
substr(decode( data_type, 'NUMBER', decode( data_precision, NULL, NULL,'('||data_precision||','||data_scale||')' ),data_length),1,11)
Also I am not able to align the output using CHR(9).
DECODE(FIELD_1,NOT NULL,'working',NULL)
Is it possible to do such? else how to proceed so?
small piece of PL SQL code. how to make this query.Requirement is that a concurrent program is run with parameters and one of them i_num_org_id is non mandatory so it can come as NULL...Now in an existing code which i have to change, it uses a query as
SELECT xyz
FROM abc_table
WHERE <various conditions>
AND DECODE(i_num_org_id,NULL,1,table.organization_id) = NVL(i_num_org_id,1);
Now with the above way, if the program is run with some value for i_num_org_id or run as normal query (with NULL as the value) inside a PLSQL procedure/package then it runs fine.This query if you run in Toad etc then too it will work fine but if it is made a dynamic SQL and then used as either EXECUTE IMMEDIATE or opened as a cursor then we get a "Missing expression". I created this small anonymous block to test this and this will go into missing expression error
declare
l_num_org_id NUMBER := NULL;
l_temp VARCHAR2(100);
l_sql varchar2(1000);
begin
l_sql := 'SELECT '||''''||'abcd'||''''||'
[code].....
how i can reformat this query so that even if NULL value comes for i_num_org_id then it is handled.I am aware about CASE but that cannot be used in WHERE clause i guess.
I have the following query:
select col_1,col_9 from
book_temp b
where b.col_1 is not null
order by to_number(b.col_16)
;
What I want to add is the following:
COL_9
=====
NULL
A
B
NULL
C
D
E
F
NULL
G
I need to connect the NON-NULL rows to the preceding NULL row.
I thought that you are not supposed to be able to assign the value of an out parameter to a variable (Feuerstein, 5th ed) and yet I was just
able to do this without any compilation error messages. Is Feuerstein wrong or am I missing something? Has the functionality changed?

I am running a GROUP BY query on a few columns of enumerated data like:
select count(*), Condition, Size
group by Condition, Size;
COUNT(*) CONDITION SIZE
-------- ---------- --------
3 MINT L
2 FAIR L
4 FAIR M
1 MINT S
Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.
For example:
COUNT(*) CONDITION SIZE SOLDDATE
-------- ---------- -------- ----------
3 MINT L ISNULL
2 FAIR L NOTNULL
2 FAIR M NOTNULL
2 FAIR M ISNULL
1 MINT S ISNULL

create table test
(
id int ,
dat date
)

I want to implement a business rule such as we have for each id at most 1 dat null. So, I've created this unique index on test.
create unique index x_only_one_dat_cess_null on test(id, case when dat_cess is null then 'NULL' else to_char(dat_cess, 'dd/mm/yyyy') end);
insert into test values (1, sysdate);
insert into test values (1, sysdate - 1);
insert into test values (1, null);
insert into test values (1, null);
-- -----
insert into test values (2, sysdate);
insert into test values (2, sysdate - 1);
insert into test values (2, null);
The 4th insert will cause an error and this is what I wanted to implement. OK. Now the problem is that for non-null values of dat, we can't have data like this
iddat
------------
124/10/2013
123/10/2013
123/10/2013
1
because of the unique index (the 2nd and the 3rd row are equal). So just for learning purposes, how could we allow at most one null value of dat and allow duplicates for non-null values of dat.

to modify column from null to not null i got this error and on this website its show successful
my steps are
first i create a table
SQL> create table Stu_Table(Stu_Id varchar(2), Stu_Name varchar(10),
2 Stu_Class varchar(10));
Table created.
Then insert some rows into Stu_Table
SQL> insert into Stu_Table (Stu_Id, Stu_Name) values(1,'Komal');
1 row created.
SQL> insert into Stu_Table (Stu_Id, Stu_Name) values(2,'Ajay');
1 row created.
SQL> insert into Stu_Table (Stu_Id, Stu_Name) values(3,'Rakesh');
1 row created.
SQL> insert into Stu_Table (Stu_Id, Stu_Name) values(4,'Bhanu');
1 row created.
SQL> insert into Stu_Table (Stu_Id, Stu_Name) values(5,'Santosh');
1 row created.
SQL> select * from Stu_Table;
ST STU_NAME STU_CLASS
-- ---------- ----------
1 Komal
2 Ajay
3 Rakesh

STU_ID VARCHAR2(2)
STU_NAME VARCHAR2(10)
STU_CLASS VARCHAR2(10)
now when i try to modify this Stu_id column to not null its give me error.

I want to install SQL Developer on a server but don't want the user to be able to store passwords by checking the "Save Password" box.
View 14 Replies View RelatedI'm trying to create a functionality on my application that lets the user change their password whenever they want or when the password gets expired.
But to do that, first I need a Branch to the page "Password Change" whenever the login procedure returns "Password Expire", but when the user has an expired password he can't access none of the pages of the application.
My other problem is:
Even if I can get the user to be redirect to the "Password Change" page, I would need a function that validate his current expired password, because in order to alter his own, he would need to inform his current password and the new one he desires. If I was using Apex Authentication that would be very easy I think, but I'm obligate to use Database Account Authentication.

I have 8 columns. Some of them might be null.I want to display all 8 columns in my result. Not null columns will be first and null at the end.Here is a sample data :

1 aaa ddd d1 100 6 180

Date xxx yyyy
1/1/12 1 1
2/1/12 null null
3/1/12 null null
4/1/12 1 1
5/1/12 1 1
