Create the view with the CLOB of TABLE data type with the LONG data type

Please need support to create the table view
Source table: (itemid varchar2, longrec)
need to create the table view Source
(itemid varchar2, CLOBrec)

A BUSINESS object must have a storage in the database, so you can't have a CLOB column in a view by pointing to a not lob data column.

create a view with the double data type

I have Windows XP with 10g 10.2.0.1.0

I need to create a view of the double and with the type of data, such as NUMBER (5.2), NUMBER or VARCHAR2 (20).
such as:
create see test (view_test varchar2 (20)) as (select view_test from double)

Help, please. Thanks in advance.

It seems a little strange, but you can do something like this with the CAST function:

SQL> create view dual_view as
  2  select cast(null as number(5,2)) col1
  3        ,cast(null as date)    col2
  4        ,cast(null as varchar2(30)) col3
  5  from   dual;

View created.

SQL> desc dual_view
 Name                                      Null?    Type
 ----------------------------------------- -------- -------------------------
 COL1                                               NUMBER(5,2)
 COL2                                               DATE
 COL3                                               VARCHAR2(30)

I used the NULL values, but you can use the actual values if you wish.

create a view with subquery generating insufficient privileges!
Hello
I want to create a view by a DB user with DBA role, the view is based on a query that extracts data from 2 users, next to the query contains the subquery. When I run the query itself - without clause CREATE VIEW - it works and gets the data, but when I try to create a view based on this request, it generates ORA-01031: insufficient privileges pointing to the subquery.
Any suggestion.

Saad,
Hello

To use the table in a view, privileges must be granted directly to the owner of the view (or public). Privileges granted to a role are not enough to use the table in a view.

How to create a view with columns from multiple lines
I posted this in the SQL/PSL forum, but I hope that experts from the database in this group can give me ideas also, the necessity is also BI reports.

I have a table, for example, project_milestones, that has these columns in order:

PROJ_ID, milestone_name, actual_end_date

with data:
PROJ_ID, milestone_name, actual_end_date
===== ================ ==============
1001, key approval, 2009-10-02
1001, final synopsis, 2009-10-07

Create a PivotTable and put "milestone_name" in the columns, under the labels section.
Put 'actual_end_date' in the section of measures and to change the rule of the aggregation of 'Max '.
The rest of the attributes keep in the lines section.

delete the order and the semicolon (;) of the first select statement. I hope you know that the operator union the same set of columns to be selected.

But try to avoid to create objects on the fly, unless and until it is absolutely necessary and inevitable.

INSERT INTO MY_ITEM_DISPLAY VALUES ('01 ', 10, '001', '003', '004',' 005');
INSERT INTO MY_ITEM_DISPLAY VALUES ('01 ', 20 '007', '013', '004',' 009');
INSERT INTO MY_ITEM_DISPLAY VALUES ('01', 30 ' 001', '004', '009',' 011');
INSERT INTO MY_ITEM_DISPLAY VALUES ('01', 40, '801 ', ' 304 ', 209',' 111');

INSERT INTO MY_ITEM_DISPLAY VALUES ('02', 30 ' 001', '004', '009',' 011');
MY_PAY_ITEMS is a table that stores line of payslip items. It has a total area of 500,000,000 lines.
PEM is the unique id, we have about 200,000 employees (with about 50,000 being active today).
PAY_PRD is a weekly pointer (2010-01, 2010-02, 2010-52), we have the 2004 data and add a new pay period each week. 2010 01 is defined as the first Monday in 2010 for the first Sunday in 2010, etc.
Key1 is an internal key, it follows the chronology in the pay period.
KEY2 is a child of KEY1, there follows the sequence of events in KEY1.
LN_ITEM is the component of actual compensation resulting from the event, on average, a person produces 20 lines per event. Note that in this example, everyone gets the same LN_ITEM values, but in practice it is selected 20 of 300
ITEM_AMT is the net salary per command line.
FILLING is a set of fields that are unrelated to this issue, but act as a brake on the charges of the line.
MY_ITEM_DISPLAY is an array that describes how some screens should display items. The screen itself is a grid of 4 poles, with the content of each cell is defined as a LN_ITEMS search to retrieve the relevant LN_AMT.
We have an application that receives a DISPLAY_CODE and an EMP. It automatically creates an sql statement in the sense of
SELECT * FROM MY_VIEW WHERE DISPLAY_CODE =: 1 AND EMP =: 2
and returns the output to the user.
My challenge is that I need to rewrite MY_VIEW as follows:
(1) (select the relevant lines from MY_ITEM_DISPLAY where DISPLAY_CODE =: 1)
(2) select the relevant all MY_PAY_ITEMS lines that meet the criteria
(a) EMP =: 2
(b) PAY_PRD = (a more recent for EMP and sysdate, so if he got last paid 2010-04, return 2010-04)
(c) KEY1 = (highest key1 in EMP and PAY_PRD)
(d) KEY2 = (highest key2 in KEY1, PAY_PRD and EMP)
(3) I then need to cross reference to create tabular output
(4) Finally, I have to return a 0 line where there is no LN_ITEMs (DISPLAY_CODE 01, 40 sequence contains possible values for this scenario)
The following query is part of it (but not the PAY_PRD, KEY1, KEy2)
Select * from)
SELECT A.DISPLAY_CODE
B.EMP
A.SEQUENCE
, MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM1, B.ITEM_AMT, 0)) 'COL1 '.
, MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM2, B.ITEM_AMT, 0)) 'COL2 '.
, MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM3, B.ITEM_AMT, 0)) 'COL3 '.
, MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM4, B.ITEM_AMT, 0)) 'COL4 '.
OF MY_ITEM_DISPLAY A, MY_PAY_ITEMS B
WHERE B.PAY_PRD = ' 2010-03'
GROUP OF A.DISPLAY_CODE, B.EMP, A.SEQUENCE)
WHERE DISPLAY_CODE = '01'
AND EMP = '0000011'
SEQUENCE ORDER
My questions
(1) how I do PAY_PRD, KEY1, KEY2 forced, can I use a form any of ROW_NUMBER() FUNCTION?
(2) how can I deal with the fact that none of the 4 LN_ITEMS column can exist (see sequence 40, none of these can exist)... Ideally the SQL above should return
01, 0000011, 10, < a digit - > < number > - < a digit - > < some number >
01, 0000011, 20, < a digit - > < number > - < a digit - > < some number >
01, 0000011, 30, < a number--> < number > - < number > - < number > -
01, 0000011, 40, 0, 0, 0, 0
I tried a UNION, but it prevented the view to eliminate most of the MY_PAY_ITEMS lines, because it solves ALL MY_PAY_ITEMS instead of simply retrieve lines for the EMP passed to the view. The same seems to be true for outer joins.

Hi Paula,

It does not handle SEQNUM 40, it's just that your second set of test data did not SEQNUM 40. When I put in the first set of values MY_ITEM_DISPLAY, I get:

DISP EMP SEQUENCE COL1 COL2 COL3 COL4

---- -------- ---------- ---------- ---------- ---------- ----------

01 00000011 10 101.1 103.1 105.1 104.1

01 00000011 20 107.1 113.1 104.1 109,1

01 00000011 30 101.1 104.1 109.1 99.99

01 00000011 40 0 0 0 0

If this isn't the issue, you will need to explain the requirement of "outer join" and what you want more. Apart from his return nothing if there is absolutely no element of remuneration of the employee, this query will always return a line for each line MY_ITEM_DISPLAY for the display_code. If there is absolutely no data, no return line seems reasonable.

Create a view with a column change journal

Hello

I have the following table:

create table test1)

number of site_number

date of change_date,

number of area_ha);

insert into test1 values (1, TO_DATE('1/1/2007','DD/MM/RRRR'), 20);

insert into test1 values (1, TO_DATE('1/1/2008','DD/MM/RRRR'), 30);

insert into test1 values (1, TO_DATE('1/1/2009','DD/MM/RRRR'), 25);

insert into test1 values (2, TO_DATE('1/1/2007','DD/MM/RRRR'), 50);

insert into test1 values (2, TO_DATE('1/1/2008','DD/MM/RRRR'), 60);

insert into test1 values (2, TO_DATE('1/1/2009','DD/MM/RRRR'), 60);

insert into test1 values (3, TO_DATE('1/1/2007','DD/MM/RRRR'), 20);

insert into test1 values (3, TO_DATE('1/1/2008','DD/MM/RRRR'), 25);

insert into test1 values (3, TO_DATE('1/1/2009','DD/MM/RRRR'), 30);

What I want to do is to have a view based on the table above which includes a column of change (change_log below) based on the anterior surface (area_ha) for each specific site_number. For example in the first line site_number 1 has increased the area of 20 hectares on the 01/01/2007 to 30 hectares on the next change_date for this site that 01/01/2008. How this could be done?

SITE_NUMBER	CHANGE_DATE	AREA_HA	CHANGE_LOG
1	01/01/2007	20	NO CHANGE
1	01/01/2008	30	ADDED SPACE
1	01/01/2009	25	DELETED DOMAIN
2	01/01/2007	50	NO CHANGE
2	01/01/2008	60	ADDED SPACE
2	01/01/2009	60	NO CHANGE
3	01/01/2007	20	NO CHANGE
3	01/01/2008	25	ADDED SPACE
3	01/01/2009	30	ADDED SPACE

I am using oracle 11g R2

Select site_number,

change_date,

area_ha,

sign of case (area_ha - lag(area_ha,1,area_ha) over (partition by order of change_date site_number))

When 1 "AREA ADDED.

When-1 then "ZONE DELETED."

Another 'NO CHANGE'

end change_log

of test1

order of site_number,

change_date

SITE_NUMBER CHANGE_DA AREA_HA CHANGE_LOG
----------- --------- ---------- ------------
1 1 JANUARY 07 20 NO CHANGE
1 1 JANUARY 08-30 ADDED SPACE
1 1 JANUARY 09 25 DELETED AREA
2 1 JANUARY 07 50 NO. CHANGE
2 1 JANUARY 08 60 ADDED SECTOR
2 1 JANUARY 09 60 NO. CHANGE
3 1ST JANUARY 07 20 NO. CHANGE

in APEX I am logged in as long as user APEX_USER and the table, I'm trying to access the site with the creation on Table Wizard form belongs to the user. I have granted all privileges on a given user APEX_USER table, the wizard allows me to choose this table in the list, but when I press the next button, I get the following error message:
You do not have access to the schema that you import. Import failed.
Contact your administrator for the application.
Seems to me that something similar had been already discussed here, but still no response.
V4.1 assistants when you use a different schema
Please, what are the rights must have my APEX_USER to be able to create forms tables belonging to someone else?
Thank you very much
Pavel
Edit: I did the same thing on my laptop (APEX 4.2.6.00.03) here and it works as expected. This error I get to work with APEX 4.2.3.00.08 (of course you should not necessarily be the cause, very likely, I don't have all of the necessary privileges) :-).

Hi Mike,.

Thanks again for your response. If the schema was not related to my workspace, I would yet be able to choose the other schema of the selection list.

In fact, there seems to be a bug in the link in my message original (for example it is still not fixed in version 4.2.3), but fortunately I was able to find a workaround - I created a view with the same name and the same structure as the original table, and then I was able to generate the form with the wizard , finally I gave up the display and modification of processes page manually. So the solution is I have to force the DBA APEX upgraded to the current version :-).

Best regards

Creating a view using multiple joins - by reducing the number of output lines

It is difficult to put into words exactly what I want to implement, so I'll just use an example. Let's say I have the following database:

game (id, time, place)

Reader (game_id, name)

Referee (game_id, name)

Foreign keys:
Player (game_id) references game (id)
Referee (game_id) references game (id)

It is a very special match, in which:
A game can have 1 to many players
A game can have from 1 to several arbitrators

I want to create the following view:

Game_overview (Game_id, time, player, referee)

It's easy to create this view with the following output:

Game1, 15:00, player1, Referee1
Game1, 15:00, player1, Referee2
Game1, 15:00, player2, Referee1
Game1, 15:00, player2, Referee2
Game1, 15:00, Joueur3, null
08:00, player1, Referee1, GaMe2
GaMe2, 08:00, player1, Referee2

HOWEVER, I want it to look like this:

Game1, 15:00, player1, Referee1
Game1, 15:00, player2, Referee2
Game1, 15:00, Joueur3, null
08:00, player1, Referee1, GaMe2
GaMe2, 08:00, null, Referee2

I think that this should not be TOO difficult to solve, but I can't really get my head around it.

Welcome to the forum!

Whenever you have a problem, please post CREATE TABLE and INSERT statements for your sample data. Sinve it's your first post, I'll do it for you:

CREATE TABLE     game
(       id          VARCHAR2 (10)     PRIMARY KEY
,     time          VARCHAR2 (10)
--,     location     VARCHAR2 (10)     -- No need to include columns that play no role in this problem
);

INSERT INTO game (id, time) VALUES ('Game 1',  '3PM');
INSERT INTO game (id, time) VALUES ('Game 2',  '8AM');

CREATE TABLE     player
(       game_id          VARCHAR2 (10)
,     name          VARCHAR2 (10)
);

INSERT INTO  player (game_id, name) VALUES ('Game 1',  'Player 1');
INSERT INTO  player (game_id, name) VALUES ('Game 1',  'Player 2');
INSERT INTO  player (game_id, name) VALUES ('Game 1',  'Player 3');
INSERT INTO  player (game_id, name) VALUES ('Game 2',  'Player 1');

CREATE TABLE     referee
(       game_id          VARCHAR2 (10)
,     name          VARCHAR2 (10)
);

INSERT INTO  referee (game_id, name) VALUES ('Game 1',  'Referee 1');
INSERT INTO  referee (game_id, name) VALUES ('Game 1',  'Referee 2');
INSERT INTO  referee (game_id, name) VALUES ('Game 2',  'Referee 1');
INSERT INTO  referee (game_id, name) VALUES ('Game 2',  'Referee 2');

In this way, people who want to help you can recreate the problem and test their ideas.

In addition, to say what version of Oracle you are using. The following query will work in Oracle 9.1 or more.

What you asked is what I call a Query, fixed-price , and this is a way to do it:

WITH     player_plus     AS
(
     SELECT     game_id
     ,     name
     ,     ROW_NUMBER () OVER ( PARTITION BY  game_id
                               ORDER BY          name
                       )         AS r_num
     FROM    player
)
,     referee_plus     AS
(
     SELECT     game_id
     ,     name
     ,     ROW_NUMBER () OVER ( PARTITION BY  game_id
                               ORDER BY          name
                       )         AS r_num
     FROM    referee
)
SELECT       g.id
,       g.time
,       p.name     AS player_name
,       r.name     AS referee_name
FROM             player_plus     p
FULL OUTER JOIN  referee_plus   r  ON   p.game_id     = r.game_id
                                AND     p.r_num          = r.r_num
JOIN           game          g  ON     g.id          = COALESCE (p.game_id, r.game_id)
ORDER BY  g.id
,         COALESCE (p.r_num, r.r_num)
;

Output:

ID         TIME       PLAYER_NAM REFEREE_NA
---------- ---------- ---------- ----------
Game 1     3PM        Player 1   Referee 1
Game 1     3PM        Player 2   Referee 2
Game 1     3PM        Player 3
Game 2     8AM        Player 1   Referee 1
Game 2     8AM                   Referee 2

I see that you have more arbitrators than players in a game. If such was not the case, then you might make it a bit more efficient using a LEFT OUTER JOIN between p and r, rather than a FULL OUTER JOIN, and you can also use only the columns of p where I use COALESCE.

Create view with different schemas
Hello

I would like to create a view using data on different patterns.

For example, user A has a table1 and user B has also a table1.
On the schema user C, I would make a union of two table in the same point of view as:

If user C is running:

Select * from A.table1
Union
Select * from B.table1

It's ok, but when I try:

CREATE or REPLACE view view_table1 AS FORCE
Select * from A.table1
Union
Select * from B.table1

It returns the ERROR at line 0: ORA-01031: insufficient privileges

But the C user has SELECT ANY TABLE, update ANY TABLE, DELETE ANY TABLE,... rights

Someone has an idea?

Thank you!

When you create a view containing the object of different owners, the other owners have to grant "with grant option" to the owner of the view. Thus, the view owner can grant to other users or patterns...

Example: The latter is the owner of a table called mine_a User_b is the owner of a table called yours_b

Let's say user_b want to create a view with a join of mine_a and yours_b

To see it working properly, it must give "grant select on mine_a to user_b with grant option.

Then user_b may grant select on this point of view to everyone.

Using DBMS_DATAPUMP with the LONG data type
I have a procedure below that calls the DBMS_DATAPUMP procedure using a REMOTE_LINK move a schema of one database to another. However, some tables in this schema have columns with the data type of LONG. And when I run it I get an error saying that you cannot move the data with the LONG data type using a REMOTE CONNECTION. So no data in these specific tables gets flying over.

Does anyone else have this problem? If so, do you have a work around? I tried to add a CLOB column in my table and affecting the new CLOB equal THROUGHOUT, but I couldn't get that to not work either... even when I tried to use a TO_LOB. If I could get that pass, then I could just slide ALONG, the schema, and then re-create the LONG column on the opposite side.

Here is my procedure...

DECLARE
/ * IMPORT/EXPORT VARIABLES * /.
v_dp_job_handle NUMBER;          -The handful of job data pump
v_count NUMBER;          -Index of the loop
v_percent_done NUMBER;          -Percentage of job complete
v_job_state VARCHAR2 (30);     -To keep track of job status
v_message KU$ _LOGENTRY;     -For error messages and work in PROGRESS

END IF;

IF v_message IS NOT NULL THEN

While v_count IS NOT NULL
LOOP
DBMS_OUTPUT. Put_line (v_message (v_count). LOGTEXT);

END LOOP;
END IF;
END LOOP;

DBMS_OUTPUT. Put_line ("' job has completed");
DBMS_OUTPUT. Put_line (' State of the Final work = ' | v_job_state);

DBMS_DATAPUMP. Detach (v_dp_job_handle);
END;
TO_LOB can be used to insert, create table in select and update the instructions to convert

So: You simply cannot use it in SELECT..., you can use CREATE TABLE BLAH AS SELECT TO_LOB (LONG_COLUMN) OF DREADED_TABLE_WITH_LONG_COL;

View with a column that is derived from a function
We can create a view with a column being filled using a pl/sql script, which uses 2 other columns on the same line as input?

Example,
Let's say I have a vision with

Reg. Don't | Total | Customer account | Flag of billing. CodeFn
$1234 45 2109 Y < value in this column would be what returns the expected script pl/sql, after using the Reg # (1234) and Total (45) as entries >
$1236 15 2101 Y < input values would be 1236 & 15 >.

Basically, I would like the script to generate a number that is returned in this column rather than do a simple Select stmt to extract columns from other tables/views.

Edit: The point of view does not display right... Here is a picture
view

Thank you!

Of course, you can use a function that you created in the same way that you would use a built-in function:
```
CREATE OR REPLACE VIEW     view_x
AS
SELECT  reg_no
,     total
,     customer_account
,     billing_flag
,     my_function (reg_no, total)     AS codefn
FROM     table_x
;
```
You cannot reference the procedures or anyonymous blocks in a CREATE VIEW statement (or any other SQL statement of stinks); only functions.

Basically, I would like the script to generate a number that is returned in this column rather than do a simple Select stmt to extract columns from other tables/views.

I don't know what you're saying here.
As long as the function has no arguments, or make any kind of DML or DDL, then you can use it in the definition of the view, as stated above. The function failed to contain SELECT statements.
Your notice must be based on other tables or views. If she does not really need anything from any other table, you can base your opinion on double. A CREATE VIEW statement must contain a query, and a query in Oracle must refer to a table or a view.

Choose a view with nested object types

I use 11.2 DB. I created 2 types of objects. The contact_t has been integrated into the student_t object and I created a view with the nested object.
How do you choose the values of the object contact_t type in the view SQL? I want to see the values of the contact_t object in speerate areas (ie. contact_name, city, Department...)
Thank you
CREATE or REPLACE TYPE contact_t () AS OBJECT
DCID NUMBER (10),
Contact_Name VARCHAR2 (50).
City VARCHAR2 (50).
State VARCHAR2 (10),
zip VARCHAR2 (10),
e-mail VARCHAR2 (100))
CREATE or REPLACE TYPE students_t () AS OBJECT
DCID NUMBER (10),
ID NUMBER (10),
last_name VARCHAR2 (50).
first name VARCHAR2 (50).
middle_name VARCHAR2 (50).
contact contact_t)

VIEW to CREATE or REPLACE students_t students_view
WITH the OBJECT IDENTIFIER (dcid) AS
Select decided,
ID,
last_name,
first name,
middle_name,
contact_t (dcid, contact_name, city, state, zip, email)
FROM MyTable

What exactly is the problem? Are you an error? An ORA-01730 by chance?

Use the default STUDENTS_T constructor in the query from the view:

VIEW to CREATE or REPLACE students_t students_view

WITH the OBJECT IDENTIFIER (dcid) AS

Select (students_t)

DECIDED

id

last_name

first name

middle_name

, contact_t (dcid, contact_name, city, state, zip, email)

)

FROM MyTable;

Then, for example:

SQL > select t.id

2, t.contact.contact_name

3, t.contact.city

4 t students_view;

ID CONTACT. CONTACT CONTACT_NAME. CITY
