Update statement with CASE and banding

Hello Folks,
I am stuck and am going nowhere.
I have two tables
MinuteCategory
Minute
MinuteCategory
MinuteLookup
MinuteCategoryId (surrogate key)
MinuteLow
MinuteHigh
MinuteCategory
Sample from Minute Lookup table ..
1 1
15 <15 min
2 16
30 <30 min
3 31
45 <45 min
4 46
60 <60 minutes
5 61
75 <1 hour 15 minutes
I am trying to update the MinuteCategory column in the MinuteCategory table using the MinuteLookup table.
For example if the minute = 33 then the corresponding lookup value would be 3 (from the lookup table), because the
33rd minute falls in between 31 min and 45 min and the corresponding surrogate key is 3
Is this possible with an Update statement in SQL? The only thing i can think of is use case statement as the join key between
the two tables but i don't think it's going to work :(
UPDATE
SET MinuteCategory = ml.MinuteCategoryId
FROM MinuteCategory mc join MinuteLookup ml on mc.Minute =
CASE WHEN mc.Minute between ml.MinuteLow and ml.MinuteHigh THEN ml.MinuteCategoryId ELSE NULL
END
Would appreciate any help.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have two tables <<
Have you read any book on data, so you have some idea what a “<something>_category” means? THINK!! A minute is unit of temporal measurement. By definition, it cannot be a category.
There is no such thing as a “<something>_category_id”; a data element is a “<something>_category” or a “<something>_id”, as per basic data modeling.
Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton.
CREATE TABLE Timeslots
(slot_start_time TIME(1) NOT NULL PRIMARY KEY,
slot_end_time TIME(1) NOT NULL,
CHECK (start_time < end_time));
INSERT INTO Timeslots --15 min intervals
VALUES ('00:00:00.0', '00:14:59.9'),
('00:15:00.0', '00:29:59.9'),
('00:30:00.0', '00:44:59.9'),
('00:45:00.0', '01:00:59.9'),
('23:45:00.0', '23:59:59.9');
Here is the basic query for rounding down to a time slot.
SELECT CAST (@in_timestamp AS DATE), T.start_time
FROM Timeslots AS T
WHERE CAST (@in_timestamp AS TIME)
BETWEEN T.slot_start_time
AND T.slot_end_time;

Update Statement With Decode and Business Dates

Hello everyone,
I need to write a UPDATE statement using business date rule. In general, the due date is 30 days from the checkout date. If the due date falls on a Saturday or Sunday then the loan period is 32 days.
I know that to test for a weekday, I'd need to use the to_char function in Oracle with the format of ‘D’. I did some research and found that to test which weekday November 12, 2007 falls on, I'd need to use the expression to_char(’12-NOV-2007’,’D’). This function returns a number between 1 and 7. 1 represents Sunday, 2 Monday, …,7 Saturday.
What I really would need to do is write one UPDATE statement using an expression with the Decode function and the to_Char function:
UPDATE book_trans SET due_dte = expression
These are the transactions that will need to be updated:
ISBN 0-07-225790-3 checked out on 15-NOV-2007 by employee 101(book_trans_id=1)
ISBN 0-07-225790-3 checked out on 12-NOV-2007 by employee 151(book_trans_id=2)
ISBN 0-201-69471-9 checked out on 14-NOV-2007 by employee 175(book_trans_id=3)
ISBN 0-12-369379-9 checked out on 16-NOV-2007 by employee 201(book_trans_id=4)
I manually calculated the due-dte and wrote update statement for each book_trans_id:
UPDATE book_trans SET due_dte = '17-dec-07' WHERE book_trans_id = 1;
UPDATE book_trans SET due_dte = '12-dec-07' WHERE book_trans_id = 2;
UPDATE book_trans SET due_dte = '14-dec-07' WHERE book_trans_id = 3;
UPDATE book_trans SET due_dte = '18-dec-07' WHERE book_trans_id = 4;
As you can see, it's very cumbersome and I'd just like to know how to incorporate everything in one Update statement:
UPDATE book_trans SET due_dte = expression
so that if due date falls on Saturday or Sunday, the loan period is 32 days; weekday, loan period is 30 days.
Any tips or help will be greatly appreciated. Thanks!

I need to write a UPDATE statement using business date rule. In general, the due date is 30 days from the checkout date. If the due date falls on a Saturday or Sunday then the loan period is 32 days. That's equivalent to saying that the due date is normally 30 days after the checkout date, but if the checkout date falls on a Thursday or Friday, then the due date is 32 days after the checkout date. I used this equivalent in the statement below.
I know that to test for a weekday, I'd need to use the to_char function in Oracle with the format of ‘D’.

This function returns a number between 1 and 7. 1 represents Sunday, 2 Monday, …,7 Saturday.That's just one way to find out the weekday, and it's error-prone because it depends on your NLS_TERRITORY setting. A more reliable way is to use 'DY' or 'DAY' as the 2nd argument to TO_CHAR. That depends on NLS_DATE_LANGUAGE, but you can explicitly set the language in the optional 3rd argument to TO_CHAR, which means your code will work the same no matter what the NLS settings happen to be. It's also easier to debug: you may have to think whether '1' means Sunday or Monday, but it's easy to remember that 'SUN' means Sunday.
What I really would need to do is write one UPDATE statement using an expression with the Decode function and the to_Char function:
UPDATE book_trans SET due_dte = expressionHere's one way:
UPDATE book_trans
SET     due_dte = checkout_dte + CASE
                                  WHEN TO_CHAR ( checkout_dte
                                         , 'fmDAY'
                                 , 'NLS_DATE_LANGUAGE=ENGLISH'
                                 ) IN ('THURSDAY', 'FRIDAY')
                         THEN 32
                         ELSE 30
                              END
WHERE   book_trans_id      IN (1, 2, 3, 4)
;This assumes that checkout date is a column in the same table.

Update statement with Case

Hi,
I need to construct an SQL Update statement that uses a case statement.
I was able to construct one:
UPDATE tableB
SET col1 = CASE WHEN (0, 0) = (SELECT col1, col2
FROM tableA
WHERE <tableA constraints> )
THEN "this value"
ELSE "that value"
END
WHERE <tableB constraints>;
But what I need to do now is to have some comparison inside the CASE WHEN statement, like:
UPDATE tableB
SET col1 = CASE WHEN (SELECT col1 from tableA WHERE <tableA constraints> > 0
AND
SELECT col2 from tableA WHERE <tableA constraints> > 0
THEN "this value"
ELSE "that value"
END
WHERE <tableB constraints>;
Basically, the case would need to pass two (or more) constraints before updating the valuefor tableB.
By the way, I was able to do this with just one constraint inside the case statement, but I need to pass more than one constraint inside the case.
Your inputs would be highly appreciated. Thanks.
Regards,

Update statement with Case syntax

UPDATE EMP a

END CASE;The closing keyword that corresponds to "CASE" is "END", not "END *CASE* ".
The string 'Y' is never equal to 'A', or to '1'.
If you have a column named y in the table, then you might want to say:
UPDATE EMP
SET EMP.TYPE = CASE
                    WHEN Y = 'A' THEN 'DIV'
                    WHEN Y = '1' THEN 'DEF'
              END;I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statemnts to re-create your emp table as it exists before the UPDATE), and the results you want from that data (that is, the contents of the emp table after the UPDATE).

Update Statement(with Case) in PL/SQL Block

Can we use Oracle case syntax (In a Update SQL)in a PL/SQL Block .
UPDATE table_name a
SET a.colum1 =
case when a.col2 IN (SELECT col1
FROM table_name1 b )
then 'Y'
else 'N'
end
It throws me an Error of code PLS-00103(This error message is from the parser. It found a token (language element) that is inappropriate in this context.)
Is there any alternative...
Thanx in Advance
null

Alas, PL/SQL has own SQL parser, and this parser dosn't know about CASE expressions (at least, it's true up to Oracle 8.1.7).
Try to use DECODE instead, something like
UPDATE table_name a
SET a.colum1 =
SELECT decode(count(*),0,'N','Y)
FROM table_name1 b
WHERE b.col1=a.colum1

UPDATE Statement with subquerry and join

I have 2 tables (say, employee and dept). employee.empno and dept.empno.
These tables are not joined.
I want to update the first name (fname) in employee WHERE employee.empno = dept.empno
My query is :
UPDATE emp SET fname='jack' WHERE exists(select * from emp,dept where emp.empno = dept.empno)
But this query updates all the records.... even where there is no corresponding record in dept
For example, emp has empno values of 10,20,30,40 and dept has empno values of 10 and 20 only,
yet all records in emp are updated.
Can someone help me ???
null

That is because an UPDATE statemente without a WHERE clause will update all of the rows.
There are three parts to an UPDATE
UPDATE tablename
SET columnlist
WHERE
The UPDATE clause specifies the table to update.
The SET clause specifies the columns to update and the values to use to update them.
The WHERE clause specified which records in the table to update.
No WHERE clause means update all rows.
The correlated subquery in the SET clause has nothing to do with the WHERE clause that determines which rows get updated. You have to be very careful to also include a WHERE clause (that often duplicates the WHERE clause in the subquery) or you will set columns to NULL that don't get values returned from the subquery.
Alias the emp table being updated and do not include the emp table in the subquery.
Also I suggest you use 'X' (or any constant that is not actually in the table) in the EXISTS test.
UPDATE emp e SET fname='jack' WHERE exists(select 'x' from dept where e.empno = dept.empno)
WHERE exists (select 'x' from dept where e.empno = dept.empno

Hi,
If all the values needed to update a given row of table_x are coming from the same row of table_y (or from the same row of a result set of a query involving any number of tables), then you can do something like this:
UPDATE table_x x
SET     (col1, col2, col3, ...)
=     (
         SELECT NVL (y.col1, x.col1)
         ,         NVL (y.col2, x.col2)
         ,         NVL (y.col3, x.col3)
         FROM    table_y y
         WHERE   x.pkey   = y.expr
         AND         ...
WHERE   ...
;If the WHERE clause depends on the same row of table_y, then it will probably be simpler and more efficient to use MERGE instead of UPDATE.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Update statement with inner join

Hello everyone. I am am trying to do an update statement with an inner join. I have found several examples of SQL statements that work with Sql server and mysql but they don't work in Oracle. Does anyone know the proper way in Oracle 10G? I am trying to update all fields in one table from fields in another table.
for example:
UPDATE table3
SET
TL3.name = TL2.name,
TL3.status = TL2.status,
TL3.date = TL2.date
FROM table3 TL3 JOIN table2 TL2
ON (TL3.unique_id = TL2.unique_id);
any help will be appreciated.

Hi,
You can also use MERGE, like this:
MERGE INTO table3     dst
USING   (
         SELECT unique_id
         ,         name
         ,         status
         ,         dt          -- DATE is not a good column name
         FROM    table2
     )          src
ON     (dst.unique_id     = src.unique_id)
WHEN MATCHED THEN UPDATE
SET     dst.name     = src.name
,     dst.status     = src.status
,     dst.dt          = src.dt
;Unlike UPDATE, this lets you avoid essentially doing the same sub-query twice: once in the SET clause and then again in the WHERE clause.
Like UPDATE, you don't acutally join the table being changed (table3 in this case) to the other table(s); that is, the FROM clause of the suib-query does not include table3.
Riedelme is right; you'll get better response to SQL questions like this in the SQL and PL/SQL forum:

Customer Statement with opening and closing balances

Dear Forum,
The users want to generate the Customer Statement with opening and closing balances like the traditional one. The statement now generated gives the list of all open items as on date, but the users want the statement with opening balances as on the date of the begining of the range specified and the closing balance at the end of the period for which the statement is generated. Is there a way to generate the same from the system.
Thanks for the help.

You can use the program RFKORD10 with correspondance type SAP06 for your company code
This program prints account statements and open items lists for customers and vendors in letter form. For account statements, all postings between two key dates, as well as the opening and closing balance, are listed.

I'd suggest you try with the MERGE statement, or alternatively, post some sample data (insert statements) and table DDL (create statements), with an 'expected output' description and we can try to help you build a suitable statement.

Hello my friends
I have one table "encompasses": continent,country,percentage
now the update should change the continent field, all "Europe" to "Asia" and all "Asia" to "America" and "America" to "Europe" by using case and just one update statement.
I wrote so and i got this error
Error starting at line 2 in command:
UPDATE encompasses
    SET continent=
       CASE WHEN continent='Europe' THEN 'Asia'
       WHEN continent='Asia' THEN 'America'
       WHEN continent='America' THEN 'Europe'
       END

*Cause:
*Action:This seems the column Continent has not null contraint on it, hence when there is a continent other than the three you mentioned above the case statement is evaluating it to null and hence failing e.g. if there is a record with continent = 'Antartica' it will try to update that as null.
so either add this:
WHERE continent in ('Europe' ,'Asia','America')this will update only for this continents and ignore other values.
If you want to update other continents as well then have a else condition in CASE statement to assign defualt value.

Dynamic UPDATE statement with parameters for column names.

Hello,
On this* website I read "The SQL string can contain placeholders for bind arguments, but bind values cannot be used to pass in the names of schema objects (table or column names). You may pass in numeric, date, and string expressions, but not a BOOLEAN or NULL literal value"
On the other hand, in this Re: execute immediate with dynamic column name update and many other
posts people use EXECUTE IMMEDIATE to create a dynamic UPDATE statement.
dynSQL:='UPDATE CO_STAT2 CO SET CO.'||P_ENT_B_G_NAME||' = '||P_ENT_E_G_WE||'
WHERE ST IN
(SELECT ST FROM STG_CO_STAT2_TEST CO WHERE
'||P_ST||' = CO.ST AND
CO.'||P_ENT_E_G_NAME||' > '||P_ENT_E_G_WE||' AND
CO.'||P_ENT_B_G_NAME||' < '||P_ENT_E_G_WE||');';
EXECUTE IMMEDIATE dynSQL ;
Since this statement is part of a Stored Procedure, I wont see the exact error but just get a ORA-06512.
The compiling works fine and I use Oracle 11g.
http://psoug.org/definition/EXECUTE_IMMEDIATE.htm

OK I extracted from all of your posts so far that I have to use "bind-variables with :"
From all the other tuorials and forums posts, I assume using the pipe is correct so I added those as well into the script:
set serveroutput on format wraped;
DECLARE
dynSQL VARCHAR2(5000);
P_ENT_E_G_NAME VARCHAR2 (100) :='test1'; P_ENT_E_G_WE VARCHAR2 (100) :='01.02.2012'; P_ENT_B_G_NAME VARCHAR2 (100) :='01.01.2012';
P_ST                VARCHAR2 (100) :='32132';
BEGIN
dynSQL:= 'UPDATE CO_STAT2 CO SET CO.'||:P_ENT_B_G_NAME||' = '||:P_ENT_E_G_WE||'
              WHERE ST IN (SELECT ST FROM STG_CO_STAT2_TEST CO WHERE
              '||:P_ST||'                           = CO.ST                  AND
              CO.'||:P_ENT_E_G_NAME||'     > '||:P_ENT_E_G_WE||' AND
              CO.'||:P_ENT_B_G_NAME||'
< '||:P_ENT_E_G_WE||')';
--this is somehow missing after the last < '||:P_ENT_E_G_WE||')';
dbms_output.enable;
dbms_output.put(dynSQL);

Update delivery with material and quantity.

hai abap gurus,
      My requirement is to create a sales order and create a delivery with sales order reference.
      I done both.But now i want to update my delivery with material and quantity.
      Is there is any bapi or function module.
      can any one help for my request.
                                                         with regards,

Hi,
You're on good way while using FM SERNR_ADD_TO_LS and SERIAL_LISTE_POST_LS .
In the second function module you don't need to pass anything.
Don't forget to make a commit work to avoid database error during synchronisation.
I had also one case of updating the serial to the document. It was the Sales order. I have worked with the function module SERNR_ADD_TO_AU which is internally using the function module SERNR_ADD_TO_DOCUMENT. The following is the sample code for it:
CALL FUNCTION 'SERNR_ADD_TO_AU'
    EXPORTING
      sernr                 = w_sernr
      profile               = c_zd01
      material              = w_matnr
      quantity              = '1'
      document              = w_vbeln
      item                  = '00010'
      debitor               = fs_header-sap_ship_to
      vbtyp                 = 'C'
      sd_auart              = w_doc_type
      sd_postyp             = w_item_cat
    IMPORTING
      anzsn                 = w_anzsn
      zeilen_id             = w_zeile
      serial_commit         = w_serial_commit
    EXCEPTIONS
      konfigurations_error = 1
      serialnumber_errors   = 2
      serialnumber_warnings = 3
      no_profile_operation = 4
      OTHERS                = 5.
IF sy-subrc eq 0.
    CALL FUNCTION 'SERIAL_LISTE_POST_AU'.
    COMMIT WORK.
ENDIF.
And one more thing, don't forget to have the call to the function module 'SERIAL_LISTE_POST_AU' amd commit work if the return code is 0. This is also mandatory.
regards
Satish
