Use of UNION in the Select statement

IM using Union of two select queries. This will return 2 rows with the same different sales with sales person. Is it possible to get in one line.

for example: name sales

Person1 100

Person2 50

Person1 50

But I need the output voltage

Sales of name

Person1 150

Person2 50

Is this possible?

Everything is possible in oracle if the requirement is clear

You can do this by using option group.

Select Name, sum (sales) as Sales from 
Group by name;

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

Classification of the UNION by the select statement
I have an SQL statement composed of a bunch of different statements of union and I would that they sort by the first Union first, then the second, then third, etc.

SELECT *.
OF SERVICE_ADDRESS
WHERE SERVICE_ADDR_ST_NUM LIKE ('% A %')
UNION
SELECT *.
OF SERVICE_ADDRESS
WHERE SERVICE_ADDR_ST_NUM LIKE ("%B %')
UNION
SELECT *.
OF SERVICE_ADDRESS
WHERE SERVICE_ADDR_ST_NUM LIKE ('%C %')

I tried a bunch of different ways, but I get an error of invalid expression;

Can someone please show me how to sort this, so that all the results come first, then the B and the C?

I left all my other tests cause well, none of them worked lol. It's just the bare bones starting point
Thanks in advance
Hello

You can do this more effectively and more easily without UNION, like this:
```
SELECT    *
FROM       service_address
WHERE       CASE
          WHEN  street_num  LIKE '%A%  THEN  1
          WHEN  street_num  LIKE '%B%  THEN  2
          WHEN  street_num  LIKE '%C%  THEN  3
       END     > 0
ORDER BY  CASE
          WHEN  street_num  LIKE '%A%  THEN  1
          WHEN  street_num  LIKE '%B%  THEN  2
          WHEN  street_num  LIKE '%C%  THEN  3
       END
;
```
If you do not want to make the same expression BOX twice, then you can do in a subquery, but then you'd have either display the results or list all service_address columns in the SELECT clause.

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 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();

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

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

IF column02 > 0 that the condition of 'Y '.
Condition IF COLUMN03 > 0 THAN 'w '.
If COLUMN04 > 0 that the condition of "Z".

TableName
where column01 > 0
Union of all the
Select "y".
TableName
where column02 > 0
Union of all the
Select 'W '.
TABLENAME

EmpName, condition, empno
Jerry, T, 0158754585
TOM, Y, 0054789568

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

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

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?

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

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.

Abram, American history Michael SOC1000 1 has 2 M 12

Is there a way to make the count gender for each sex, introduce yourself as a column in the SELECT statement so that there is only ONE row returned by course number with as FEMALECOUNT and MALECOUNT column headers?

I tried to use a statement select count nested inside the original SELECT statement but without success.

Jeff
You should be able to use a CASE statement for this in collaboration with the County. COUNTY does not indicate that null instances no I have not specified a part to the CASE ELSE (so the default value is NULL).
```
COUNT(CASE ST.GENDER WHEN 'F' THEN 1 END) as Female_count,
COUNT(CASE ST.GENDER WHEN 'M' THEN 1 END) as Male_count, 
```
Note that you need to remove the Gender of your query column.
