Disqualification - CASE or DECODE statement writing

Test

Edited by: user4362313 may 3, 2013 05:00

Hi Bala,

If I interpreted the statement correctly, then you are wanting fill the digits left of the decimal point to four characters, so 12.345 becomes 0012.345.

The best way to achieve this is by using a processor of Expression (see the online help for details of full syntax). Assuming that the input attribute is called 'col1' then the following expression should lead to the desired result:

substr ('000' | col1, indexof (col1, ".") - 1).

Kind regards
Nick

Need help in writing the SQL CASE or DECODE statement
Hi experts,

I need to write a SQL select order_num, cntry_cde, prod_id and Qty by joining order_num on PROD_ORDER and PROD_ORDER_TXT.

Here is my sample data

PROD ORDER_
order_num Prod_id Qty cntry_cde
100 US A1 5
101 US 10 A2
102 IN A3 4
103 TO THE A4 9
104. IN A5 3

PROD ORDER_TXT_
cntry_cde Prod_id order_num
100 US A1
101 US A2
102 NZ A3
103 TO THE A4
A5 104

Here's the requirement,

(1) if the cntry_cde in PROD_ORDER is the same as cntry_cde in PROD_ORDER_TXT then select PROD_ORDER.cntry_cde (orders 100, 101, 103)
(2) if they are different, choose PROD_ORDER_TXT (order 102, to THE NZ <>) country code
(3) if they are different and PROD_ORDER_TXT.cntry_cde is null, I can't use it like cntry_cde in my report (order 104). It happenend just because of bad data to the source.
I can't avoid it. Then just use the cntry_cde of PROD_ORDER

Expected results
100 US A1 5
101 US 10 A2
102 NZ A3 4 - changed in NZ
103 TO THE A4 9
104. IN A5 3 - IN retained as PROD_ORDER_TXT.cntry_cde is null

instructions for creation and insertion of sample table are lower than

create the table prod_order
(number of order_num,
cntry_cde CHAR (2),
prod_id VARCHAR2 (6).
number of quantity)

create the table prod_order_txt
(number of order_num,
cntry_cde CHAR (2),
prod_id VARCHAR2 (6))

insert into prod_order values (100, 'WE', 'A1', 5);
insert into prod_order values (101, 'WE', 'A2', 1);
insert into prod_order values (102, ' to THE ', 'A3', 4);
insert into prod_order values (103, ' to THE ', 'A4', 9);
insert into prod_order values (104, 'IN', 'A5', 3);

insert into prod_order_txt values (100, 'WE', 'A1');
insert into prod_order_txt values (101, 'WE', 'A2');
insert into prod_order_txt values (102, 'NZ', 'A3');
insert into prod_order_txt values (103, ' to THE ', 'A4');
insert into prod_order_txt values (104, 'A5', NULL);

Problem with Decode statement
Hello

I try to do the following in my report:

If an employee is a family name. (dot) or a name of. (dot), the report does not display a point. An employee name consists of the family name, first name and middle name, which should all be concatenated sets. An attempt to achieve this goal, I have the following statement in my report:

Decode (e.Surname, '.', (LTRIM (RTRIM ((INITCAP (e.FIRST_NAME))) |))) » '|| INITCAP (e.MIDDLE_NAME))),
e.FIRST_NAME, '.', (LTRIM (RTRIM ((INITCAP (e.Surname))) |)) » '|| INITCAP (e.MIDDLE_NAME))),
(LTRIM (RTRIM ((INITCAP (e.SURNAME))) | ',' |)) INITCAP (e.first_name) | » '|| INITCAP (e.MIDDLE_NAME))) as emp_name

E employee

Problem: The above statement only works for employees with the name of. (dot). It doesn't for the first names of dot. How to use the decode statement OR is there another way to do it without using the CASE statement?

It seems my decode statement does not work with 2 different fields (name, first name) tested within the decode statement. Thank you.
LTRIM and RTRIM the comma too:
```
select rtrim(ltrim(rtrim(ltrim(', Somename ,',','),','))) Name
from dual;

NAME
--------
Somename
```

No CASE or DECODE
I have a table with say a column called 'COLOUR' with 500 different values - lets say 3 values are red white and blue. There are 497 other

I want to insert table with the column of color in another table called 'OTHER '.
But whenever I hit a blue, I want to insert red instead. All other values remain the same as they are.
I tried CASE and DECODE, but it leaves me with NULL values for others 497 values. Is there a way to do saying only when I hit the blue, I want it to be red, without hard-code all other values? For example:
Insert into ANOTHER table
Select
COLUMN1,
COLUMN2,
COLUMN3,
COLOR (if color is blue, red insert - then let all the other colors to be what they are)
COLUMN 5
It would be useful to show the CASE statement that failed. But I think that you would
```
INSERT INTO destinationTable( list_of_columns )
  SELECT list_of_columns,
         (CASE WHEN color = 'BLUE' THEN 'RED' ELSE color END) color
     FROM sourceTable
```

DECODE statement and the argument limits
No one knows the number of arguments that the DECODE statement allows you to enter. I currently have 863 and it gives me an error message when I try to run the query.

Database - ORA-00939 error: too many arguments for the function.

Thank you
Chris
Hello

You still have too many parameters your decodes, the limit is 250 so you can enter only 124 values and decoded. I would like to nest decodes by doing:

DECODE (point, "c1", "v1", "c2", "v2", "c3", "v3",..., DECODE (point, 'c4', 'v4', 'c5', 'v5', 'c6', 'v6',..., DECODE (...)))

Alternatively, you can for example use case

WHEN BOX point IN ( END)

Calculation grouping using decode statement?
I have 4 sales reps who are numbered 9801, 9802, 9803 VRP, 9804.

I have 3 support staff that support accounts by virtue of these representatives of REPS 1, 2, 3

Support rep 1 will support the commercial attaché 9801 & 9802
Support rep 2 will support the commercial attaché 9802 and 9803
Support rep 3 will support the commercial attaché 9803 & 9804.

Initially, I had a report which gave the results for all listed sales reps. The representatives of support and then imported it into excel and delete the records of the sales reps that they do not need.

I want to create a page filter that will support rep select its name in a drop-down which shows only sales reps they support. So support rep 1 can select their name from the drop down and the report would only show information for the commercial attaché 9801 & 9802.

I tried to do this with a calculation using the decode statement, but it does not work. It seems only to associate support rep to each sales representative. Is there a way to accomplish the grouping I want?

DECODE (put into commercial service Rep.Sales,
9801,'REP ' 1,.
9802,'REP ' 1,.
9802, ' REP 2',
9803, ' REP 2',
9803, ' REP 3',
9803, ' REP 4'.
9804, ' REP 4'.
"ERROR")
Hello

I don't think you can do it easily if you want to use a filter on the page. This is because if a row is returned by the database that has a sales of 9802, then, the line must be on 2 pages.

You can create a parameter to select the support rep and use this setting to select the records. Therefore, if the parameter is p_support_rep then you have a condition like:

(: p_support_rep = 'REP1' AND sales_rep IN (9801, 9802)) OR
(: p_support_rep = "REP2' AND sales_rep IN (9802, 9803)) OR
(: p_support_rep = "REP2' AND sales_rep IN (9803, 9804))

If you really need to use a filter on the page, then you will need to use a generator of line to create a line for each support rep and to join your generator line report by using a report similar to the one above. You can search for "Generator line" of this forum, or check out the learndiscoverer blog (http://learndiscoverer.blogspot.com/2008/10/row-generators.html) for more details.

Help in to convert CASE to DECODE in 11g sql

11 GR 2, Windows.

Can someone help me rewrite under sql CASE statement to DECODE?

SELECT INVOICE_ID,sum(TOTAL_EXCL_VAT),LEVEL2 as descr,
sum(case when instr(LEVEL2,'Internet')>0 then SUM_QUANTITY else 0 end) as KB  --- >> Here
from rator_cdr.INVOICE_DETAIL_LINE

group by LEVEL2,INVOICE_ID;

Thank you

Why would you want to replace the much more expressive syntax of CASES with a DECODING?

If you are really determined

DECODE( instr( level2, 'Internet' ), 0, 0, sum_quantity )

I would strongly prefer the option CASE, however.

How to use the case and decode to extract data

Hello gurus of PL/SQL,.

I use Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64-bit Production version

How to use CASE or DECODE into that?
Hi, I have a query like this
```
AND ...smthng
AND --smtg
AND age BETWEEN ....
```
For the last clause AND the age column, I have the values passed param in the AOC as strings
0 '-30', 31-60, 61-90, and ' 91 +'. The setting IN of course is VARCHAR2.

What I want to do in this clause AND
for example, for age will '' 0-30, the clause AND should be

AND BETWEEN age (if this interval is 0 '-30' then) AND 30 0 (if it falls between 31-60'), then BETWEEN 31 AND 60... and so on...
However this BETWEEN will work up to 61-90 of range but for 91 +, there is no upper limit so it should be
AND age > 91

Now, I don't know how to achieve both BETWEEN and ' > ' clauses in the same statement AND.

DECODE will not work and do not know how to use the CASE in this situation that even this cannot solve this problem.

Don't want to do the last clause AND Dynamics

Please suggest me how to do this.

Thank you
Aashish

A third possibility would be to choose a sufficiently high value as a high-end for the Group 91 + and use something like:
```
age between to_number(CASE WHEN instr(:param, '+') = 0
                              THEN substr(:param, 1, instr(:param, '-') -1)
                              ELSE substr(:param, 1, instr(:param, '+') -1) end) and
            to_number(CASE WHEN instr(:param, '+') = 0
                           THEN substr(:param, instr(:param, '-') +1)
                           ELSE '9999' END)
```

Here's the script:

WITH got_delimited_list AS
(
SELECT address_line1 || ' +' ||
address_line2 || ' +' ||
address_line3 || ' +' ||

This is equivalent to

SELECT  (address_line1 || ' ')    || '+' ||

     (address_line3 || ' ')    || '+' || ...

You are guaranteeing to all areas will result in a space, and therefore may not be NULL.
Lose the spaces before the signs +:

Hello

You can still use DECODE instead (and you can always use CASES instead of DECODE and should almost always).

I agree with Someoneelse and Alex: this is an example of a situation in this CASE is better than DECODE.
```
DECODE ( a.os_rec_status
       , 'PC'           , a.os_rec_ref
                        , DECODE ( INSTR ( ',IT,GA,CL,AR,'

                             )
                      , 0       , NULL

                             SELECT  pcy_ref
                             FROM    con_cla_sub_apr_view
                             WHERE   CLA_REF     = A.OS_REC_REF
                             AND         byr_ref     = a.code
                             AND         cla_sub      = (
                                                  SELECT  MAX (CLA_SUB)
                                          FROM       con_cla_sub_apr_view
                                          WHERE       CLA_REF     = A.OS_REC_REF
                                          )
                             )
                      )
     )
```
This assumes that os_rec_status never contains commas.

I can't imagine a situation in which DECODE would be significantly faster this CASE.
I imagine many situations in which the CASE is significantly faster than DECODE.
I expect, in this case, THAT CASE is only slightly faster than DECODE.

I have a table called t_criteria of columns 'criterion_1', 'criterion_2' and criterion_3' with line for each column being either 'Yes', 'No' or 'not known '. (See the DOF below)

What I want is a statement that will give the number of criteria which have been fulfilled (i.e. the line 'Yes') in a list separated by commas in a column called 'criteria_met '.
I know how to do this in excel but do not know how I would go about it in oracle?
It is a way to do this in excel:
"= SUBSTITUTE (TRIM (IF(B2="Yes",1,)" ") &" "& IF(C2="Yes",2,)" "") &"" & IF(D2="yes",3,) "" ")),""," ")"
When column B is criterion_1, column C is criterion_2 and column D is criterion_3.
I use the database 11g r2

create the table t_criteria
(the number (2) of site_id not null,)
criterion_1 varchar2 (25).
criterion_2 varchar2 (25).
criterion_3 varchar2 (25).
key primary constraint site_id_pk (site_id)

Case logic OF statement?
The problem:

In our society, there are several physical tables of the same type of information and data. Instead of storing everything in a single table, they differentiated by the company.

If the commands that may exist in sales_130 for the United States, but sales_244 to the Germany. Structure wise, they are the same. I have the cursor that identifies the data I need to acquire, and which company resides. So I go by the logistics company to get the data in the correct tables. Unfortunately, I need to join many tables and there are between 50 and 100 fields on that I need to update/delete/insert. Having to build all the SQL for each case when its only the tables that change becomes very tedious and difficult to manage.

Is there a way I can put a case or something like that in the part OF the clause so I did not do the following:
```
IF LOGISTIC_COMPANY = 130 THEN

INSERT INTO TEMP_ABCDEF
 (LOG_COMP, A,B,C,D,E,F)
 SELECT
   244, X.A, X.B, X.C, Y.D, Y.E, Y.F

To something like:
```
 INSERT INTO TEMP_ABCDEF
 SELECT
   130,
   X.A,
   X.B,
   X.C,
   Y.D,
   Y.E,
   Y.F
 FROM
 (  
 IF LOGISTIC_COMP = 130 THEN
   ABC130 X,
   DEF130 Y
 ELSIF LOGISTIC_COMP = 244 THEN
   ABC244 X,
   DEF244 Y
 ELSIF LOGISTIC_COMP = 387 THEN
   ABC387 X,
   DEF387 Y  
 ELSEIF ......

 )
WHERE 
   X.A = Y.D(+);
```
I tried different vain things.

In the light of the foregoing, I will for concept, not the correct syntax to explain because I have no idea how to put into words. There must be a way to simplify the SQL code so that I don't manage the business logic - as in the paintings and without having to rewrite while the IF-THEN-ELSE statements.
That's what it would look like, assuming that the only thing that changes is that the logistic_company still appears at the end tables:
```
  EXECUTE IMMEDIATE 'INSERT INTO TEMP_ABCDEF (LOG_COMP, A,B,C,D,E,F) ' ||
                    'SELECT ' || LOGISTIC_COMPANY  || ', X.A, X.B, X.C, Y.D, Y.E, Y.F'
                    'FROM   ABC' || LOGISTIC_COMPANY || ' X, DEF' || LOGISTIC_COMPANY || ' Y ' ||
                    'WHERE  X.A = Y.D(+)';
  COMMIT;
```

BOX WHEN in DECODE statement

SELECT v_startdate, v_enddate,
(CASE WHEN SYSDATE BETWEEN v_startdate AND v_enddate THEN
'active '.
ON THE OTHER
'inactive '.
Status of END)
OF correction_tab;

Could you kindly guide as to how to use DECODE and get the desired result.

Thank you
Rami Reddy.

You can, like this.
However, the CASE seems much clearer for me so why bother with a DECODING?

sql> with correction_tab as
  2    ( select trunc(sysdate)-1 as v_startdate, trunc(sysdate)   as v_enddate from dual
  3    union all
  4      select trunc(sysdate)   as v_startdate, trunc(sysdate)+1 as v_enddate from dual
  5    union all
  6      select trunc(sysdate)+1 as v_startdate, trunc(sysdate)+2 as v_enddate from dual
  7    )
  8  SELECT v_startdate
  9  ,      v_enddate
 10  ,      CASE
 11           WHEN SYSDATE BETWEEN v_startdate AND v_enddate
 12             THEN 'active'
 13           ELSE 'inactive'
 14         END status
 15  ,      decode ( sign(sysdate-v_startdate), 1, decode(sign(v_enddate-sysdate), 1, 'active', 'inactive'), 'inactive')
 as status2
 16  FROM correction_tab
 17  /

V_STARTDA V_ENDDATE STATUS   STATUS2
--------- --------- -------- --------
12-DEC-12 13-DEC-12 inactive inactive
13-DEC-12 14-DEC-12 active   active
14-DEC-12 15-DEC-12 inactive inactive

CASE with MIN statement?

I am trying to write a case statement that says what STAT is select E MIN (TERM)
If there are several TERMS that are both low just choose No. Want a line by ID.
Is this possible using case?

Thank you.

CREATE TABLE DAN_GR2
(ID    VARCHAR2(12),
TERM    VARCHAR2(12),
STAT VARCHAR2(12)) 

INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('1','5','E')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('1','2','D')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('1','9','E')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('1','5','E')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('2','1','E')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('2','10','E')
INSERT INTO DAN_GR2 (ID, TERM,STAT) VALUES ('3,'10','D')

ID      TERM     STAT
1     5     E
1     2     D
1     9     E
1     5     E
2     1     E
2     10     E
3       10      D

Here you are

ID   MIN_TERM   
1     5     
2     1
3     NULL

Hello

So, you don't want to ignore the whole when line stat! = 'E' (that ignores the single row with id = "3"). Put the condition ' stat = 'E' in the sill of the WHERE clause ignores line, so this isn't what you want.
You want to just ignore the expression column. Put the same condition in a CASE expression that contols only this column.

Here's one way:

SELECT       id
,       MIN ( CASE
                 WHEN  stat = 'E'
              THEN     term
             END
           )          AS min_e_term
FROM      dan_gr2
GROUP BY  id
ORDER BY  id
;
