Using the conditional to determine the Select statement

I don't know if anyone knows if I can do that, but I try to use a factor based on a value on what query to run...

Something like:

DECODE('INBOUND', 
     'INBOUND', SELECT 'I' FROM DUAL, 
     'OUTBOUND', SELECT 'O' FROM DUAL, 
     'BOTH', SELECT 'B' FROM DUAL);

SELECT * 
      FROM 
      ( 
           CASE 
                WHEN '<~S~>' = 'INBOUND' THEN SELECT 'INBOUND' FROM DUAL 
                WHEN '<~S~>' = 'OUTBOUND' THEN SELECT 'OUTBOUND' FROM DUAL 
                ELSE SELECT 'BOTH' FROM DUAL 
           END 
       ) AllValues

Is it still possible?

Thank you
Andy

Scalar subqueries should appear in square brackets, for example

select case dummy
          when 'X' then (select 'First example' from dual)
          when 'Y' then (select 'Second example' from dual)
       end as demo
from dual;

or if you prefer the old syntax DECODE,

select decode(dummy,
              'X', (select 'First example' from dual),
              'Y', (select 'Second example' from dual)
       ) as demo
from dual;

How to pass parameter in the function using the select statement?
Hello

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

Try like this
```
select * from table(select splitfunction(lot_no) from tracer_search_schedule where job_id='36')
```
Just make sure that your subquery returns only 1 row.

How to display the data type long using the select statement
Hai All

I have to select the text of a view. But the text is declared as long and I need to see full view

When I use this

Select the text in all_views where view_name = "DAILY_ATTEND_VIEW";

I have got only half of a select statement

Concerning

Srikkanth.M
Hello
```
SQL> SET LONG 100000
SQL> select text from user_views
  2   where view_name='MVIEW';

TEXT
------------------------------------------
select e.empno,e.deptno,d.dname
from emp@sdblink e,dept@sdblink d
where e.deptno=d.deptno
```
But it is limited to sql alone. If you use the double click TOAD on the text column in the grid will show you the entire SQL views.
Unfortunately, there is limitation to consider,
The largest value that you return from the function would be 32 k (RETURN VARCHAR2), both.

Update using the Select statement
I have a requirement of the main table was updated. Here is an example
Example (a) works in PL SQL but does not work in Forms6i.
Example (b) works in PLSQL so in Forms 6i.

I need work example (a) in forms 6i. What is the solution

one)
UPDATE fman_validation_master SET TOT_HRS = TOT_HRS +.

Hello

According to Oracle 8.1, you can say:
```
UPDATE  table_x
SET     column_a = exp;
```
where exp is any expression, or
```
UPDATE  table_x
SET     column_a = (ssq);
```
where ssq is now called a scalar subquery. Oracle 8.1 sometimes allowed scalar subqueries in places where the documentation did not say that they were allowed. The first statement is an example, when you use
```
tot_hrs + (ssq)
```
as an expression. It works in SQL * Plus and also in PL/SQL, but (apparently) not in the forms.

Re-write your UPDATE statement so that the scalar subquery appears in itself to the right of the sign =, like this:
```
UPDATE     fman_validation_master
SET     tot_hrs =
     (
     SELECT     fman_validation_master.tot_hrs + SUM (fav.tot_hrs)
     FROM     fman_actqty_validation     fav
     WHERE     fman_validation_master.project          = fav.project
       AND     fman_validation_master.activity_code     = fav.activity_code
     )
WHERE     project = :control.project;
```
In other words, just move the original fman_validation_master.tot_hrs (to which you add the SUM) of the main request in the subquery.

Insert a variable + string using the select statement with cfquery

I'm doing an insertion by a select statement where the insert for one of the fields should be a combination of a vaule comes from the selection and concatenated with a string of text. Is this possible and if what the correct syntax so? Here is an example of what I'm trying, but does not.
< name cfquery = "createnote" datasource = "#application.datasource #" >
INSERT INTO gtbl_notes (notedate, strCustomerID, notetype, note, notecreatedby)
SELECT "#currentdate #", strCustomerID, "miscellaneous", "#gtbl_people.email # DELETED because of HARD BOUNCE ', 'Bounce Routine.
OF gtbl_people, gtbl_bounces
WHERE gtbl_bounces.email = gtbl_people.email AND gtbl_bounces.subscriber = 1 AND gtbl_bounces.status = 2
< / cfquery >
Any input would be greatly appreciated.

Concatonation is possible with most, if not all of the databases. The syntax is a specific software and you do not your specify.

Need help with the use of GROUP BY in a select statement UNION

I am writing a query that allows to combine a legacy system that interfaces it is trial balance in the Oracle of R12 GL. It was only meant to continue for a month or two, but it is likely to continue for 6 months. Please Auditors Auditors, to provide proof that the system is in balance with Oracle GL. By my verification requirements, I need to make a full reconciliation from the month of conversion (life in the amount of date), then PTD for each month.

The legacy account is placed in attribute1 on the lines of the journals. Uses of the old system balancing segments that are also used on the platform in Oracle for this division, i.e., Procure-to-Pay has been cut over Oracle, but not everything yet. So, I can't count on the GL_BALANCES table for the info, I get from the JE_LINES.

My problem is not the only request for the month. But when I try to combine the queries with a Union, to aggregation of each measurement period in its own column, the group is necessary after each selected instruction rather than allowing me to put at the end of the UNION. (When I put the group by at the end of the UNION, I have the 'not one group' function)

So I get duplicate for each month of discrete measure accounts. When I duplicate in my Oracle database accounts, I can't count on the VLOOKUP function in excel to exactly match an account of inheritance. I know there are more sophisticated ways to provide this output, but I'm hoping to get this info in a simple query.

Thank you in advance for any advice you can provide

Example of data output (the goal for me is to get the two rows to appear as one based on common points on the LEGACY_ACCOUNT and the ORACLE ACCOUNT

The LEGACY ACCOUNT	ORACLE ACCOUNT	JUN_15	JUL_15	AUG_15	SEP_15	OCT_15	NOV_15	DEC_15

Here is a simplified version of my code that returns both records. In my research, I had found a number of conversations where it has been shown that the group could be put at the end of the select statement. However, when I remove the group from the first select statement I get SQL error: ORA-00937: not a function of simple-group

How to use the Type of Oracle Table values in the Select statement.
Hello

I get the initial set of values in the Table of Type Records of the Oracle and want to use the list of values in the Select statement.

For example, try something like the following:

TYPE t_record () IS RENDERING
ID TABLEA.ID%type,
NO TABLEA.NO%type

);
v_record t_record;
T_table TYPE IS the v_record TABLE % TYPE;
v_table t_table;

-Code to fill the values of v_table here.

SELECT ID, NO, COLLECT in BULK IN < some other table variabes here > FROM TABLEA
WHERE ID IN (i) v_table USER.USER;

I want to know how to use the Type of Oracle Table values in the Select statement.
Something like this:
```
create or replace type t_record as  object (
id number,
no number
)
/

CREATE or replace type t_table AS TABLE OF t_record;
/

set serveroutput on
declare

  v_table t_table := t_table();
  v_t1 t_table := t_table();

begin

  v_table.extend(1);
  v_table(1).ID := 1;
  v_table(1).No := 10;

  v_table.extend(1);
  v_table(2).ID := 2;
  v_table(2).ID := 20;

  SELEC t_record (ID,NO) BULK COLLECT INTO v_t1
  from TableA
  FROM TABLEA
  WHERE ID IN (select t.ID from table(v_Table) t);

  for i in 1..v_t1.count loop
    dbms_output.put_line(v_t1(i).ID);
    dbms_output.put_line(v_t1(i).No);
  end loop;
end;

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

uniol all in the select statement

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
My use case is
IN the column State
If column01 > 0 to condtion 't'
IF column02 > 0 that the condition of 'Y '.
Condition IF COLUMN03 > 0 THAN 'w '.
If COLUMN04 > 0 that the condition of "Z".
Select 't'
TableName
where column01 > 0
Union of all the
Select "y".
TableName
where column02 > 0
Union of all the
Select 'W '.
TABLENAME
WHERE COLUMN03 > 0
I have what it takes to show value as it
EmpName, condition, empno
Jerry, T, 0158754585
TOM, Y, 0054789568
Am in oracle database 11 g 2

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

Of

(

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

Union of all the

Select empname, empno, condition of 'Z', 4 myorder FROM tablename WHERE COLUMN04 > 0

) a

) where rn = 1

function() nested in the select statement

Oracle 11g. Try to nest a function within the select statement. Goal: get the average customer rating for each of the qualified user.
Select user_name, f_get_avg_cust_rating() "Notation.
of u, OTHER_TABLES o TAB_USER
where u.id = o.id and another condition matched;
How Oracle would deal with the sql. Is it
(1) first of all display records based on the where clause, then call the f_get_avg_cust_rating() for each of the selected records OR
(2) for the analysis in tables, the f_get_avg_cust_rating() will be called for each record met?
