SQL & PL/SQL :: Decode Functionality With Null
Jun 29, 2010Explain 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'
SQL & PL/SQL :: Using NULL And DECODE In Dynamic Query
Sep 2, 2011small 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.
SQL & PL/SQL :: Hierarchical Query - Connect NON-NULL Rows To Preceding NULL Row
Aug 29, 2012I 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.
SQL & PL/SQL :: Counting NULL Vs NON-NULL In A GROUP BY Clause
Jun 21, 2010I 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
SQL & PL/SQL :: Date Field - Not Null Column To NULL
Mar 16, 2011I 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)
SQL & PL/SQL :: Unique Null And Multiple Non-null
Oct 24, 2013create 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.

SQL & PL/SQL :: Decode On One Line
Jul 28, 2010I tried writing a decode statement but it doesn't work as expected. The data I'm working has 4 different brand names with an associated code. I tried using decode to get the 4 brands to be on one line like this: Description, Inventory_Item, Product_Line, Product_Type, Brand_1, Brand_2, Brand_3, Brand_4..I still get 4 lines with the Brands displayed like a stair steps.
What do I have to do to get the data on one line? My code is as follows:
SELECT sgk_invfg_organization_items.description,
sgk_invfg_organization_items.inventory_item,
sgk_invfg_organization_items.product_line,
sgk_invfg_organization_items.product_type,

But this gives an error...If the decode gives a "single"...the statement is working fine...but If the decode gives a "range"...the above statement gives an error saying "missing keyword"..Does the above code when mapped to "Range"...is it not producing "and" like " value between 100 and 1000"

Using 2 Tables With Decode Function
Nov 8, 2009What I have to do is this:
List supplier�s name, id, number of pending orders, number of completed orders and number of all orders from this supplier. (my query doesn't include the last part yet).
My tables are as follows:
Suppliers:
S_ID
NAME
ADDRESS
PROVINCE
PHONE_NUMBER
Orders:
ORD_ID
SUPPLIER_ID
ISSUING_EMP_ID
ORDER_DATE
ORDER_STATUS
and this is what I have so far:
select name, s_id
sum(decode(order_status, 'P',1,0)) pending,
sum(decode(order_status, 'C',1,0)) completed
from suppliers
where s_id in
(select supplier_id from orders);
but I still get an error that says "sum(decode(order_status, 'P',1,0)) pending,
*
ERROR at line 2:
ORA-00923: FROM keyword not found where expected"
I assume this is because I'm not properly referencing the orders table.
Decode Based On Different Column
Jul 24, 2007Is it possible to decode based off a different column? I have a status column that i want to change the value of with a decode, but only if my date column has been populated.
So if status has a value of "New" and my date column is null, then i want it to stay new. If it is populated, i want my status to change to "released"
SQL & PL/SQL :: DECODE And CASE In WHERE Clause
May 7, 2010I am facing a problem while retrieving data from table using DECODE/CASE.
Table: PARAM_MSTR
MIN_VALMAX_VALPARAM_CODE DESCRIPTION DATATYPE
AB1000 HARD PARAMETERTEXT
CN1000 SOFT PARAMETERTEXT
0501001 CRYSTAL PARAMETERNUMBER
512001001 STONE PARAMETERNUMBER
Now I want to get the parameter description based upon the PARAM_CODE and a value passed which should be in range of MIN_VAL and MAX_VAL. Means when I pass PARAM_CODE=1000 and :parameter=A, then it should check the DATATYPE of the PARAM_CODE, in our case it is 'TEXT' so it should check the passed value between MIN_VAL and MAX_VAL like
:parameter BETWEEN MIN_VAL AND MAX_VAL and should return 'HARD PARAMETER'.
If I pass PARAM_CODE=1001, then the DATA_TYPE is 'NUMBER', so it will check the :parameter value as Number.
Like :parameter BETWEEN to_number(MIN_VAL) AND to_number(MAX_VAL)
For example:
PARAM_CODE :parametr Result
1000 A HARD PARAMETER
1000 C SOFT PARAMETER
1000 P NULL
1001 25 CRYSTAL PARAMETER
1001 99 STONE PARAMETER
1001 201 NULL
I have written a query using DECODE and CASE statement but it is not working properly.
SELECT * FROM param_mstr WHERE PARAM_CODE=1000 AND :parameter BETWEEN DECODE(DATATYPE,'NUMBER',CAST(MIN_VAL as NUMBER),MIN_VAL)AND DECODE(DATATYPE,'NUMBER',CAST(MAX_VAL as NUMBER),MAX_VAL)
