Is there a way to replace a field with another if the particular value returned is null?
View 11 Replies View RelatedI am looking to replace the vowels in a string, and get rid of the empty spaces afterwards.
Our Lab Book suggested that we use the REPLACE function, but I have only been able to get it to work using the TRANSLATE function.
Also, I can`t figure out how to get the empty spaces out of the string when output, I tried to use the TRIM command unsuccessfully.
1) Is it possible to use REPLACE instead of TRANSLATE to replace the vowels?
2) How would i get rid of the empty spaces when the vowels have been replaced?

I have a scenario where I have to get all the available dates of a resource. I am using the below query to get it.
Select Avail_Date AS MONTH
, Resource_Id
FROM res_tsk
, (SELECT Rownum - 1 + TRUNC (sysdate) avail_date
FROM Dual
[code].......
The result of this is:
Month Dates Resource_ID
12/3/10 0:00 NULL
12/4/10 0:00 NULL
12/5/10 0:00 NULL
12/6/10 0:00 100033868
As I am doing a outer join, if the resource is not available on a particular day the resource_id is coming as NULL as it is not available. Is there any way to populate this NULL resource_id with the original resource_id as the resource_id is same for all the result set.
I need the output to be
Month Dates Resource_ID
12/3/10 0:00 100033868
12/4/10 0:00 100033868
12/5/10 0:00 100033868

I have a table with no primary key constraints with some roles containing null value/duplicates. I then decided to alter the table to add composite primary key constraints on four columns (a, b, c, and d). I did this by using the same script that was used to create the original table but this time adding the not null constraints.
I then took and export of the original table. I now want to import the data to the newly created table but I am now getting the error: ORA-01400: cannot insert NULL into (string).
I will like to perform the import without NULL. Is there a parameter in impdp that I can use? I tried DATA_OPTIONS=SKIP_CONSTRAINT_ERRORS but it didn't work.
Beside options using impdp is there a way to do an insert statement like this insert into table a (select * from table) excluding NULL;?
Basically, I need to load the data into the newly created table without NULL.
My DB version is 10.1.0.5.0
I want extract the values from the string using below query but i am unable to bring the correct result.
WITH t AS ( select '123,1,3,22' col FROM DUAL
UNION ALL
SELECT '123,,2,1' FROM DUAL
UNION ALL
SELECT '5,1,2,,' FROM DUAL
)

My required result like below.
123 1 3 22
123 2 1
5 1 2
get required result using regular expressions.
I have an already populated table that refers to a wrong foreign key in another table. I have table abc that has the column fk_id. this column currently refers to column x_id1 in the table abc while it should refer to column x_id2 in xyz. I am trying to replace the data but I guess I miss something in the logic or the right way of doing it:
following is my trial:
create table abc
(
pk_id number(4) primary key,
abc_name varchar2(10),
fk_id number(4)
);
create table xyz
(
x_id1 number(4),
x_id2 number(4),
x_name varchar2(10)
);
commit;
insert all
into abc values (10,'ab1',1)
into abc values (11,'ab2',2)
into abc values (12,'ab3',5)
into abc values (13,'ab4',7)
into abc values (14,'ab5',9)
into xyz values (1,1,'d1')
into xyz values (2,2,'d2')
into xyz values (5,3,'d3')
into xyz values (7,4,'d4')
into xyz values (9,5,'d5')
select * from dual;
commit;
--this following select returns 5 rows
select * from abc, xyz where abc.fk_id = xyz.x_id1;
-- the following update only updates 3 rows and sets the other 2
-- to null!
update abc set fk_id = (select x_id2 from xyz where xyz.x_id1 = abc.fk_id);
commit;
select * from abc;
In forms 11 g, whenever, We did any menu change, and deploy in server, same changes are not reflecting in clients machine immediatly. I even stop forms services and restart.After some time... generally after 1 day, it reflect the new changes.In forms 10G, I never face this issue. As soon as i close the old menu and re-open, new changes reflect.
View 2 Replies View RelatedI am doing some ETL that I need to run "faster". The function in which I am interested removes low ascii code characters from a string. Please see the timing below and the definitions of the of the functions below those. I am selecting just the first 100K rows for testing and timing purposes only. In production, we are doing millions of records several times a day, thus the desire for "faster". Selecting with no functions is very fast, 0.2 seconds. We would really really want to convert at least 100K rows per second.
The best I can do is get it down to around five seconds using clear_nonlegal. That is, ironically, the one that I thought would be the slowest. It's making thirty-one calls to REPLACE. I would have guessed that the other two would be much faster. I am guessing that REPLACE is just much better optimized than TRANSLATE and, of course, my homegrown PL/SQL, which isn't optimized at all.
So, my question is thisif there is a way I can optimize my custom function, or maybe know of a better already optimized standard SQL and/or Oracle function that would do the job? I am thinking about trying to use a Java stored procedure, but I have never done that before, I am not currently set up for it, if it would be any faster anyway. Is Java faster with string manipulation the PL/SQL? I am thinking it would be really fast to call a C method,

I did an expdp on the prod DB and have been doing a straight impdp as a test, just to have data to work with, but it spews 214 errors. Mostly these:
ORA-31684 lots
ORA-39083 some
ORA-39151 lots
ORA-39082 lots
ORA-39111 lots
ORA-39112 lots
I can see that I can use REUSE_DATAFILES & TABLE_EXISTS_ACTION to overwrite tables by default, but is there a recognised way of replacing the entire DB with the impdp? Do I just create the instance, (with the init file) and not build/init the tables, or what? I'll experiment, but I'm just interested if there is a DBA best practice for this sort of thing.
why the REPLACE function is not replacing. I assume it has something to do with the ASCII value being zero.

How can I replace the function call by the join in the main query?
Getting starting with diving deeper into APEX and reading the developers guide all 800 pages of it! Thing is I'd like to get started with some of the more interesting stuff.
I have created a form page based on the "Form on a Table with Report". The report part looks fine. What I'd like to do now is use an API I've built to change how the insert and update works. So when the submit button is pressed it rather performs an API call to the procedure/function.
1. Should the API be a function or procedure. In my playing around I saw that a procedure might work better or easier to implement
2. How would I go about creating a call for the button to use instead of the current processes?

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

I have a table which has a not null column. the column is date field. I am trying to change it to Null. But it is giving a error.
I am using below query.
ALTER TABLE T_test
modify (paid_to_date null)
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

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.
when i follow this steps mention on this website

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
4 Bhanu
5 Santosh
Table Structure is like this
SQL> Describe Stu_Table
Name Null? Type
----------------------------------------- -------- ----------------------------
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.
SQL>ALTER TABLE Stu_Table MODIFY Stu_Id int(3)not null;
ALTER TABLE Stu_Table MODIFY Stu_Id int(3)not null
*
ERROR at line 1:
ORA-01735: invalid ALTER TABLE option
and when i try to add new column with not null its also gives me error
SQL> ALTER TABLE Stu_Table add C1_TEMP integer NOT NULL;

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 :
Employee table :
Employee_id Emp_fname emp_lname emp_mname dept salary emp_height emp_weight
1 aaa ddd d1 100 6 180
2 bbb ccc 120 169
3 dfe d2 5.9 223
The expected result is :
result1 result2 result3 result4 result5 result6 result7 result8
1 aaa ddd d1 100 6 180
2 bbb ccc 120 169
3 dfe d2 5.9 223
I have this error (and solution):
ORA-02085: database link string connects to string
Cause: a database link connected to a database with a different name. The connection is rejected.
Action: create a database link with the same name as the database it connects to, or set global_names=false.
Where should I set global_names=false ?
I'm facing some problem even after using INSTR function in Oracle.The problem is I have written the logic in the PL/SQL block which appends all the values fetched in a loop on the basis of whether the string is present or not.
For ex:
The first value fetched from the select query first is ABCDEFG which gets appended to a variable
The next value fetched is AB even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The next value fetched is BCDEF even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The third Value fetched is ABCDEFG this will not get appended presently according to the logic which is correct.
writing that piece of code to append the value fetched which doesn't exactly match with the existing string
Initially i have inserted the data into table like
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
6/1/12 null null
in above example data is null for some date here my requirement is how can i copy before not null data(1/1/12) to *2/1/12, 3/1/12* .

emp records the empid, emp_name, deptid
dept records the deptid, dept_name

I have the following problem.
I have a trigger "before update" that change some values, including a timestamp column. My sql code does an update using the "returning clause" to get the values changed by the trigger. The problem is:
When I do an "update [...] returning timestamp_field", this timestamp_field has the old value equals to null (in the trigger). And, this field in the table is not null. This problem not occurs with the others fields of type number, varchar... only with the timestamp field.
Here are the code to simulate this problem:
--Table
create table TB_TEST
(
ID NUMBER(10) not null,
FLAG NUMBER(10) not null,
TAG VARCHAR2(16) not null,
TS_ATU_DTR TIMESTAMP(9) not null
);

exec test1;
select * from textolog order by data, texto;

"old.TS_ATU_DTR=, " Isn't it right?????
Why the other fields aren't null?
I need the "old.TS_ATU_DTR" to use in my other trigger to compare timestamps, how can I get it?
Or, is there a patch for this problem?
MY requirment is: I want the first three nullable attributes. For Eg: If I have 60 columns in table, I need to fetch the first three null data in a row.
