Update statement with Aggregate function

Hi All,
I would like to update the records with sum of SAL+COMM+DEPTNO into SALCOMDEPT column for each row. Can we use SUM function in Update statement. Please help me out this
See below:
Table
CREATE TABLE EMP
EMPNO NUMBER(4) NOT NULL,
ENAME VARCHAR2(10 CHAR),
JOB VARCHAR2(9 CHAR),
MGR NUMBER(4),
HIREDATE DATE,
SAL NUMBER(7,2),
COMM NUMBER(7,2),
DEPTNO NUMBER(2),
SALCOMDEPT NUMBER
Used update statement :
UPDATE emp e1
SET e1.salcomdept= (select sum(sumsal+comm+deptno) from emp e2 where e2.empno=e1.empno)
WHERE e1.deptno = 10
commit
Thanks,
User

Adding these columns makes no sense, so I'll assume this is just an exercise.
However, storing calculated columns like this is generally not a good idea. If one of the other columns is updated, your calculated column will be out of sync.
One way around this is to create a simple view
SQL> CREATE view EMP_v as
2 select EMPNO
3        ,ENAME
4        ,JOB
5        ,MGR
6        ,HIREDATE
7        ,SAL
8        ,COMM
9        ,DEPTNO
10        ,(nvl(sal,0) + nvl(comm,0) + nvl(deptno,0)) SALCOMDEPT
11 from   emp;
View created.
SQL> select sal, comm, deptno, salcomdept from emp_v;
                 SAL                 COMM               DEPTNO           SALCOMDEPT
                 800                                        20                  820

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

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.

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.

                                 , 'NLS_DATE_LANGUAGE=ENGLISH'
                                 ) IN ('THURSDAY', 'FRIDAY')
                         THEN 32
                         ELSE 30
                              END

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.

Insert statement with loop function

Hello all,
I'm new with the loop function
What need to do is to use a select statement with a condition
This output needs to be inserted in a table
The values of the condition are stored also in a table
It will be something like this:
BEGIN
FOR i IN (select nrs from table1) LOOP
    INSERT INTO table_out_loop
    SELECT * FROM bigtable_vw
    WHERE nr = i
END LOOP ;
END ;
I cant use a direct insert_into function in this case so I need the plsql to 'look' for the values 1 by 1 from the table1
Any help would be appreciated

Can't you just:
    insert into table_out_loop
    select *
    from   bigtable_vw
    where nr in (select nrs from table1);
If not, then post a better example and/or rephrase the question...

Problem with aggregate function

Hello,
the prerequisite is to have a table with the following columns (#id, a_date).
Now the task is to select the maximum date from a range of rows of this table
select max(t.a_date)
from the_table t
where <condition to get only some rows of the_table>
and to get the id of the record which holds the maximum date. That's where the problem is located. It should look like the following code (yes, I know this cannot work because grouping by the id makes the aggregate senseless) just to make clear what I want to do.
select max(t.a_date), t.id
from the_table t
where <condition to get only some rows of the_table>
group by t.id
Does anybody have any idea how to solve the problem?
With regards,

Hi all,
as the condition in the where-clause is very complex, I decided to use the solution with the FIRST function. After googling and reading a bit, I have just two more questions for my deeper understanding:
1) am I right that both snippets below do exactly the same?
SELECT MAX (t.a_date)
, MAX (t.ID)KEEP (DENSE_RANK FIRST ORDER BY t.a_date DESC)
FROM the_table t
WHERE <condition to get only some rows of the_table>
SELECT MAX (t.a_date)
, MAX (t.ID)KEEP (DENSE_RANK LAST ORDER BY t.a_date ASC)
FROM the_table t
WHERE <condition to get only some rows of the_table>2) can I use als the min function for t.ID as there the aggregate function does not have any effect (but is necessary in order to use KEEP and FIRST or KEEP and LAST)?
With regards,

Join tables with aggregate function

Hello
I have 4 views that I need to perform aggregate function, count, on and then join them for query output.
Basically each view has a column with a score and a subcontractor name. One subcontractor may have more than one score in each view.
Here is the sql that I'm working with thus far:
select e.sub_name, (count(e.score) - 1), (count(v.score) - 1), (count(s.score) - 1), (count(u.score) - 1)
from speed.v_ratings_ex e, speed.v_ratings_vg v, speed.v_ratings_sat s, speed.v_ratings_uns u
where v.sub_name = e.sub_name
and s.sub_name = e.sub_name
and u.sub_name = e.sub_name
group by e.sub_name
order by e.sub_name asc;
This results in each column returning the same value b/c the join is performed before the aggregate function.
Can anyone offer some help so that I may get the desired results?

You need to use in-line views to perform the aggregates, then join the in-line views.
Something like:
SELECT e.sub_name, e.score - 1 escore, v.score - 1 vscore,
       s.score - 1 sscore, u.score - 1 uscore
FROM (SELECT sub_name,count(*) score
      FROM v_ratings_ex
      GROUP BY sub_name) e,
     (SELECT sub_name,count(*) score
      FROM v_ratings_vg
      GROUP BY sub_name) v,
     (SELECT sub_name,count(*) score
      FROM v_ratings_sat
      GROUP BY sub_name) s,
     (SELECT sub_name,count(*) score
      FROM v_ratings_uns
      GROUP BY sub_name) u
WHERE v.sub_name = e.sub_name and
      s.sub_name = e.sub_name and
      u.sub_name = e.sub_name
ORDER BY e.sub_name asc;TTFn

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.

Update statement with nested selects and alias usage

Hello, we are trying to build an update statement like this...
update table1 t1
set attr1 = ( select someattr
from (nested select 1) as aux1
(nested select 2 (nested select 2.1 + nested select 2.2)) ) as aux2
where some_join_clauses
where t1.attr2 = 123
and t1.attr3 = 'abc'
Alias t1 shound be known at the level of nested select 1,2 and 2.1, 2.2? We are receiving an error message saying that t1.someattr is an invalid identifier. Can you help? Thanks!

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.

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;

Ask Tom has very good discussion about this, if UPDATE does not work for PK issue, you can use MERGE

Update statement with Case syntax

I want to put case statement in an update statement using Oracle 10g
I'm getting a syntax error on the last line Ora-00933: SQL command not properly ended
Help please
UPDATE EMP a
SET EMP.TYPE = CASE
WHEN 'Y' = 'A' THEN 'DIV'
WHEN 'Y' = '1' THEN 'DEF'
END CASE;

Help please
UPDATE EMP a
SET EMP.TYPE = CASE
WHEN 'Y' = 'A' THEN 'DIV'
WHEN 'Y' = '1' THEN 'DEF'
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).
