SQL & PL/SQL :: What Does DECODE Do
Sep 7, 2011
Just working with Unix for the first time and trying to understand this decode statement?
cursor l_cursor is select decode(type||'-'||to_char(line,'fm99999'),
'PACKAGE BODY-1','/'||chr(10), null) ||
decode(line,1,'create or replace ', '') ||
decode(type||'-'||to_char(line,'fm99999'),
'JAVA SOURCE-1','and compile ' || type || ' named "' ||
name || '"' || chr(10) || 'AS' || chr(10), '') ||
text text
from user_source
where upper(name) = upper(p_name)
order by type, line;

Which warehouses have pending orders for products, which are not in stock at the warehouse at the moment? Provide warehouse number, id of the product that is not in stock, number of orders issued for this product and total quantity ordered.
The tables I am using are
Warehouses:
Name Type
----------------------------------------
W_ID NUMBER(38)
CITY VARCHAR2(20)
W_SIZE NUMBER(38)
Inventories:
Name Type
-----------------------------------------
P_ID NUMBER(38)
W_ID NUMBER(38)
QUANTITY NUMBER(38)
Orders:
Name Type
-----------------------------------------
ORD_ID NUMBER(38)
SUPPLIER_ID NUMBER(38)
ISSUING_EMP_ID NUMBER(38)
ORDER_DATE DATE
ORDER_STATUS CHAR(1)
This is my code so far:
select w.w_id, i.p_id,
sum(decode(o.ord_id, ' ', i.p_id, 0)) Orders_issued,
select sum(i.quantity)
from
inventories i
orders o,
[code]...
but I get this error:
select sum(i.quantity)

I have a scenario where in report table I need to get
IF FLAG='Y' AND LOC=118443 THEN STATE='FIN'
IF FLAG='Y' AND LOC!=118443 THEN STATE SHOULD BE ('COMP','PART')
IF FLAG='N' IT SHOULD INCLUDE ALL STATES.
I tried using decode in WHERE CLAUSE , but not successful.
Create Table Report(Id Number,Loc Number,Flag Varchar2(3),State Varchar2(20));

Insert Into Report Values(1,1,'Y','COMP');
1 rows inserted.
Insert Into Report Values(2,118443,'Y','FIN');

I 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,
Decode(sgk_item_master_launch_v.sgk_model_item, 20,
sgk_item_master_launch_v.sgk_model_number) brand_1,
Decode (sgk_item_master_launch_v.sgk_model_item, 30,

I have a small doubt...Without any creation of tables as I feel it's not needed...(let me know if u need them) Error says "Missing Keyword"
select distinct record_number
from meta m, procedu b, control v, fact f, calendar dc, person p
where f.key = m.key and f.group_key = b.group_key
and b.proc_key = v.proc_key
and f.calendar_key = dc.calendar_key
and f.person_key = p.person_key
and VALUE BETWEEN DECODE((Select distinct operator_type
[code]....
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"

What 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.

Is 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"

I 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)

I have used a decode statement in my query instead of using select * from <table_name> where value in <>
Instead I have used decode(value,<value1>, <value2>)
Which would be a better performance code?

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).

Here is one an example with CASE WHEN statement.
SELECT empno,ename,sal,
CASE
WHEN sal BETWEEN 800 AND 1200
THEN 'Lowest Pay'

even DECODE can be a replacement for this scenario, but it cannot have as flexibility as CASE can have.
Now, I want Equivalent code for DECODE..

I'm having some trouble writing this query using a decode statement within a join. First, lets say I have two tables. Table A has the fields 'Baseline', 'NAD', 'Null', and 'Harn'. Table B has the fields 'Null', 'NAD', and 'Harn'. I want to join these tables together by these fields to return their ID's. Because table B doesn't have 'Baseline' to even have a match between the two tables, in Table A, we want to treat 'Baseline' as 'Harn', hence a decode statement. My query is below
Select
...
...
...
From
...
inner join oracle_srid_xref B on A.horizontal_datum = B.horizontal_datum and
decode(A.horizontal_epoch, 'BASELINE', 'HARN', loc.horizontal_epoch ) = B.horizontal_epoch
I'm not getting the ID's where the horizontal_epoch was initially 'Baseline'
