Update using a function in the select statement

Hello

Is it possible to do the follwing.

I tabele and a custom function, the custome service will update the column (amount) of the table based on the value of going through the function of the select statement.

SELECT id, stock, where an id = get_update (id);

Now

Get_update function will return the same id I'm passing and update the column amount to a value in the
table a.

When I run the satament selection I have the updated data in the column amount in my first executtion, but if execute the same statement, again, I see the changes reflected. is it possible to get data updates to the first performance himself.

the function is of type PRAGMA AUTONOMOUS_TRANSACTION

Concerning

Indeed a strange requirement and probably not the way to go in a production environment. But anyway is a way to achieve your goal

SQL> create table a
as
   select   12 id, 500 amount from dual
   union all
   select   13 id, 600 amount from dual
/
Table created.

SQL> create or replace type a_typ as object (id number, amount number)
/
Type created.

SQL> create or replace function get_id (pid number)
   return a_typ
is
   pragma autonomous_transaction;
   l_a_typ   a_typ := a_typ (null, null);
begin
      update   a
         set   amount = 800
       where   id = pid
   returning   id, amount      into   l_a_typ.id, l_a_typ.amount;

   commit;

   return l_a_typ;
end get_id;
/
Function created.

SQL> select   id, d.a_typ.amount amount
  from   a, (select get_id (13) a_typ from dual) d
 where   id = d.a_typ.id
/
        ID     AMOUNT

You post p_startdate and p_enddate, so I can't test with them.

I had a problem. I can't pass as parameter to the function by using the select statement. But it can pass as a parameter using the "code". How can I solve this problem?

For example,.
Select * from table (SplitFunction ('HS750020, HS750021')) < < < this work.

but

Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) < < < do not work.

Thank you for trying to help him. Thank you.

using variable in the select statement (php)
I have trouble using a variable in a select statement.

The following query to manually (using a static date) works very well:

$query_Recordset1 = "SELECT * from academyClasses WHERE the classDate > ' 2006-06-01' ';"

However, if I use the following:

$dateVar = date('Y-m-d');

@mysql_select_db ($database_mw, $mw);
$query_Recordset1 = "SELECT * from academyClasses WHERE the classDate > $dateVar";

All records are returned, which means that the $dateVar variable is not recognized. I compared the values of $dateVar <? PHP echo $datetime;? > against the real value of my date field <? PHP echo $row_Recordset1 ["classDate"];? > in my results to the table and it seems that the values are indeed accurate regarding a date 2006-06-04 for example.

My date field 'classDate' is of type 'date' in the mysql database. I use Dreamweaver MX 2004 with Mac OSX 10.3.9.

I'm sure it's just a syntax problem, at least, I hope it is.

Any help is greatly appreciated.

It worked:

$query_Recordset1 = "SELECT * from academyClasses WHERE the classDate > = CURRENT_DATE;

Thank you

Return multiple values from a function in a SELECT statement
I hope I've provided enough information here. If not, let me know what I'm missing.

I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).

Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.

For example, right now, I have:

Table 1:
sequence_number NUMBER (10),
name varchar (30),
...

Table2:
Table1_seq NUMBER (10),
action_seq NUMBER (10),
action_date DATE,
action_office VARCHAR (3),
action_value VARCHAR (60),
...

I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.

The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
RP.action_date (sequence_number) action_date,
RP.action_office (sequence_number) action_office,
RP.action_value (sequence_number) action_value
FROM table1

Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?

Any suggestions?

Thank you very much!
Hello

What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:
```
WITH     got_rnum     AS
(
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
)
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;
```
As written, this returns a single line (at most).
I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
In this case, add a PARTITION BY clause to the ROW_NUMBER function.
If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
As I don't have your tables, I'll show you the use of the tables in the scott schema.
This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.
```
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
(
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate
     ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                               ORDER BY          e.hiredate
                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
)
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
;

SELECT     *
FROM     senior_emp
;
```
Output:
```
.    DEPTNO DNAME               EMPNO ENAME      HIREDATE
---------- -------------- ---------- ---------- ---------
        10 ACCOUNTING           7782 CLARK      09-JUN-81

        30 SALES                7499 ALLEN      20-FEB-81
```
Moreover, one of the conditions to the query you posted has been
```
action_office     LIKE 'E'
```
which equals
```
action_office     = 'E'
```
(AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
Did you mean say that or did you mean something like this:
```
action_office     LIKE 'E%'
```
Instead?

# You can call functions, but not procedures.

If the procedure does not change the State of the database (for example, it isn't updated all tables), then you can wrap it in a function, or re - write function.

Here is an example of wrapping.
```
CREATE OR REPLACE FUNCTION fun_x (in_txt IN VARCHAR2)

        proc_y (in_txt);

Hi I have a situation where I have to return the value based on the if statement, is it possible to put union all in the select statement

If column01 > 0 to condtion 't'
IF column02 > 0 that the condition of 'Y '.

If COLUMN04 > 0 that the condition of "Z".

where column02 > 0
Union of all the

Yes you can put all THE UNION here

Select empname, 't' State, empno from tablename where column01 > 0

Union of all the

Select empname, 't' State, empno from tablename where column02 > 0

Union of all the

Select empname, condition of "W", empno FROM tablename WHERE COLUMN03 > 0

Union of all the

Select empname, condition of "Z", empno FROM tablename WHERE COLUMN04 > 0

and if you are looking for how to remove duplicates because your line might have satisfied all the conditions and my happen 4 times in your result set, you just need to give them an order and filter it.

For example, you want this

If column01 > 0 to condtion 't'

ELSE IF column02 > 0 that the condition of 'Y '.

Another condition of THAN > 0 IF COLUMN03 'w '.

otherwise if COLUMN04 > 0 that the condition of "Z".

Select empname, condition, empno, in

Select a.*, row_number() over (partition by empno arrested by myorder) rn

(

Select empname, 't' State, empno, 1 myorder tablename where column01 > 0

Union of all the

Select empname, 't' State, empno, 2 myorder tablename where column02 > 0

Union of all the

Select empname, condition of "W", empno 3 myorder FROM tablename WHERE COLUMN03 > 0

validation for each 1,000 records to be inserted in the select statement
Hi, I have the following INSERTION in the SELECT statement.
The SELECT statement (who joined) data fo about 6 crores. I need to insert this data into another table.

Please suggest me the best way to do it.
I use the INSERT in the SELECT statement, but I want to use the statement commit for each 1,000 records.

How can I do this...
```
insert into emp_dept_master 
 select e.ename ,d.dname ,e.empno ,e.empno ,e.sal 
   from emp e , dept d
  where e.deptno = d.deptno       ------ how to use commit for every 1000 records .
```
Thank you
Method 4 is the best

You could combine method 3 and 1 (without dynamic SQL)

Method 2 is the less optimal solution from the list.

Update using a function in the select statement
