Query with DECODE function

My table has columns A,B & C with data as below
A B C
X 1 1
1 X 1
1 1 X
Result should be all ‘Z’ inserted right to ‘X’ & must look like as below
A B C
X Z Z
1 X Z
1 1 X
Please check the below query & help me to modify the query as the result for column b is not correct.
select a,decode(b,'1','Z','X') b,decode(c,'1','Z','X') c
from test;

try
With Data As
Select 'X' A,'1' B, '1' C From Dual Union All
Select '1','X','1' From Dual Union All
Select '1','1','X' From Dual
Select A, (Case When A ='X' And B='1' Then 'Z' Else B End) B,

Error while replacing IF statements with DECODE function in procedure

Hi All,
I have created a procedure which has nested IF statements. Now I want to replace the IF statements with DECODE functions to improve performance.
Procedure:
IF (var_int_sev = '0')
THEN
var_sev := '2';
ELSE
SELECT sev
INTO var_int_sev
FROM errorconfig
WHERE errorcode = var_errorcode;
var_sev := var_int_sev;
END IF;
I converted the above IF statement into DECODE function as mentioned below:
var_Sev := DECODE(var_int_sev,0,2,SELECT severity FROM errorconfig WHERE errorcode=var_ErrorCode)
But it throws below error at the select statement used inside DECODE.
Error(58,51): PLS-00103: Encountered the symbol "SELECT" when expecting one of the following: ( - + case mod new not null others <an identifier> <a double-quoted delimited-identifier> <a bind variable> avg count current exists max min prior sql stddev sum variance execute forall merge time timestamp interval date <a string literal with character set specification> <a number> <a single-quoted SQL string> pipe <an alternatively-quoted string literal with character set specification> <an alternativ
Can someone help me in converting the IF to DECODE in the above case. Also how can we use a select statement inside decode.

instead of trying to rewrite all your code and hoping that the performance will be better, it's a better option to investigate and find out which part of your application is slow

OWB3i - Validate with DECODE function

Hi,
in OWB 3i when I validate an expression defined inside an expression operator with DECODE() function (which is not include in default transformation) come this error:
Line 1, Col 1:
PLS-00204: function or pseudo-column 'DECODE' may be used inside a SQL statement only
but it seems only a warning because when i generate the scripts and run no other error happen and all works fine.

Hi,
Welcome to the forum!
When you use a default value, the last argument to DECODE is the actual value you want as a default.
For example:
SELECT       ename
,       deptno
,       DECODE ( deptno
             , 30     , 'Sales'
                  , 'All others'     -- Default value
              )                 AS dname
FROM      scott.emp
ORDER BY ename
;Output:
ENAME          DEPTNO DNAME
ADAMS              20 All others
ALLEN              30 Sales
BLAKE              30 Sales

SMITH              20 All others
TURNER             30 Sales
WARD               30 Sales
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
If you can show the problem using commonly available tables (such as those in the scott schema) then you don't need to post any sample data; just the results and the explanation.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Problem in Query with JOIN Function in OCRD CRD1 OCPR tables

Hello Dear Forum Users,
I want to make a query which shows me per business partner from OCRD - Addres; CRD1 - Delivery Address and from OCPR - Contactperson information
Is it possible to show it in one row per Business Partner. Now I get (the classic problem) of several rows and a duplication of the contact persons per (delivery) address.
My query is:
SELECT T0.[CardCode], T0.[CardName], T1.[Address], T1.[Street], T1.[ZipCode], T1.[City], T1.[Country], T1.[U_TelNr], T1.[U_MobNr], T1.[U_OpenTijd], T1.[U_LosIns_1], T1.[U_LosIns_2],T2.[Title], T2.[Name] as 'Voornaam', T2.[Address] as 'Achternaam', T2.[Position] as 'Functie', T2.[Tel1], T2.[Cellolar], T2.[E_MailL], T2.[BirthDate] FROM OCRD T0 LEFT OUTER JOIN CRD1 T1 ON T0.CardCode = T1.CardCode LEFT OUTER JOIN OCPR T2 ON T0.CardCode = T2.CardCode
Can you help me ?

Changed the query with Left Outer Join

I have found the solution myself:
By using the Union All function I could combine two queries. Here is the result:
SELECT
T0.[CardCode], T0.[CardName], T1.[Address] , T1.[Street], T1.[ZipCode], T1.[City], T1.[Country], T1.[U_TelNr], T1.[U_OpenTijd] , T1.[U_LosIns_1] , T1.[U_LosIns_2]'
FROM OCRD T0 LEFT OUTER JOIN CRD1 T1 ON T0.CardCode = T1.CardCode
WHERE T0.[CardCode] >= 'D00000'
Union all
SELECT
T0.[CardCode], T0.[CardName], T2.[Position], T2.[Tel1], T2.[Title], T2.[Name], T2.[Address], T2.[Position], T2.[Tel1], T2.[Cellolar], T2.[E_MailL]
FROM OCRD T0 LEFT OUTER JOIN OCPR T2 ON T0.CardCode = T2.CardCode
WHERE T0.[CardCode] >= 'D00000'
Order by 1
Now i got the result I was looking for.

Between clause with DECODE function.

Hi All,
I have one table which has object, date and quantity columns, Now based on date range I can find out the objects and quantity but the question is: I want a query which returns all the objects and should show quantity 0(zero or null) for those objects which don't falls under that date range. So I thought to use a decode function but it only uses the relational operation, I thought something like this but it's wrong,
select object,decode(created_date,BETWEEN '01/01/2008' TO '08/01/2008',quantity,0) from table;
Does anyone have any idea how can I make this work in single sql statement?
Thanks for your help.

Is that important column order in a query with row_number function

Hi folks,
I am using Oracle 11g R2 on HP-UX machine.
I have 2 types of query with row_number and I think they are same but output of each of them are different. I changed only column order in query2.
Query 1 :
(SELECT
"LOOKUP_INPUT_SUBQUERY"."CONTRACT_SK" "CONTRACT_SK",
"LOOKUP_INPUT_SUBQUERY"."SIMCARD_SK" "SIMCARD_SK"
FROM (
SELECT row_number ()
OVER (
PARTITION BY "R_CON_SUBS_SIMCARD_LK".
"CONTRACT_SK"
ORDER BY
"R_CON_SUBS_SIMCARD_LK"."START_DATE" DESC,
"R_CON_SUBS_SIMCARD_LK"."SEQ_NUM" DESC NULLS LAST) /* EXPRESSION_3.OUTGRP1.SIRA */
"SIRA",
"R_CON_SUBS_SIMCARD_LK"."CONTRACT_SK" "CONTRACT_SK",
"R_CON_SUBS_SIMCARD_LK"."SIMCARD_SK" "SIMCARD_SK"
FROM "SRC_OZRDS"."R_CON_SUBS_SIMCARD_LK" "R_CON_SUBS_SIMCARD_LK")
"LOOKUP_INPUT_SUBQUERY"
WHERE ("LOOKUP_INPUT_SUBQUERY"."SIRA" = 1))
Output of this like that :
CONTRACT_SK SIMCARD_SK
1     1
1     3
1     4
1     5
1     6
1     11
1     12

1     15
1     16
Query 2 :
(SELECT
"LOOKUP_INPUT_SUBQUERY"."CONTRACT_SK" "CONTRACT_SK",
"LOOKUP_INPUT_SUBQUERY"."SIMCARD_SK" "SIMCARD_SK"
FROM (
SELECT
"R_CON_SUBS_SIMCARD_LK"."CONTRACT_SK" "CONTRACT_SK",
"R_CON_SUBS_SIMCARD_LK"."SIMCARD_SK" "SIMCARD_SK",
row_number ()
OVER (
PARTITION BY "R_CON_SUBS_SIMCARD_LK".
"CONTRACT_SK"
ORDER BY
"R_CON_SUBS_SIMCARD_LK"."START_DATE" DESC,
"R_CON_SUBS_SIMCARD_LK"."SEQ_NUM" DESC NULLS LAST) /* EXPRESSION_3.OUTGRP1.SIRA */
"SIRA"
FROM "SRC_OZRDS"."R_CON_SUBS_SIMCARD_LK" "R_CON_SUBS_SIMCARD_LK")
"LOOKUP_INPUT_SUBQUERY"
WHERE ("LOOKUP_INPUT_SUBQUERY"."SIRA" = 1))
Output of this like that:
2     874812
7     70097256
8     18734091
9     158024

22     5829949
23     35348926
25     3865978
I expected the second output, because there are lots of contract sk but there is one contract_sk in first query result. i did not get the point. What is the problem ?

I changed only column order in query2.So what else do you expect? If you order, for example, by last name, fist name don't you think rows will be returned in a different order (and therefore same row will have different row number) than ordering by first name, last name?

Try formatting your columns
col type for a4
col frequence for a4
col amount for a4
although from looking at you query, I don't understand the
output you pasted. YOu have 3 decode statments based on the
same fields?

Problem with decode function.

Hi,
Can anyone of you help me out in solving this?
It is like i wish to give different select statements according to the value of a parameter entered by user USING DECODE FUNCTION.The select statement contains some other select statements inside it.So when i execute it,it is giving error like 'ORA-00913-too many values(even when i enclose select statements within brackets).

ORA-00913 too many values
Cause: The SQL statement requires two sets of values equal in number. This error occurs when the second set contains more items than the first set. For example, the subquery in a WHERE or HAVING clause may return too many columns, or a VALUES or SELECT clause may return more columns than are listed in the INSERT.
Action: Check the number of items in each set and change the SQL statement to make them equal.
the above is from oracle documentation. the brackets is not the problem, u must be using multiple items in the integrated decode queries. If the problem still exists post ur DML for further analysis.

Odd Error with decode function in Order By Clause

I am trying to compile a procedure and can't get around an error with a dynamic order by that doesn't make much sense to me. I can repoduce the error with a plain select statment in sql plus so I can rule out a declaration error. Here is an example with 2 numeric columns and a date column.
select task_id, display_date, remark_id from task_list
where task_id > 1000
order by decode('Task_ID', 'Task_ID',Task_ID, 'Display_Date', Display_Date, 'Remark_ID',Remark_ID)
returns the error:
select task_id, display_date, remark_id from task_list
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected NUMBER got DATE
I'm not sure why this error is occuring, because it doesn't even hit the Display_Date field in the Decode statment. If I take the Display_date out of the statement, it runs properly. If I change Display_Date to To_Char(Display_Date) it also runs fine, but the sorting is incorrect. Also I'm running 9.2, and do not want to use dynamic sql to build my query. Any Ideas out there as to the cause of this error?

I did find a workaround to this issue by breaking the decode statment into three separate statement, but I still think that the way it is written above should work, and may be a bug, or an error that I don't understand fully.
The Order by was rewritten like this:
order by decode(pSort, 'Task_ID',Task_ID), decode(pSort, 'Display_Date', Display_Date),
decode(pSort, 'Remark_ID',Remark_ID);
Thanks
