Name of the table mistakenly renamed
HelloI've migrated a MySQL existing database to the oracle database.
MySQL database had a few tables and columns with length > 30, as oracle does not support the length > 30 so it automatically renamed length 30 characters by removing the last characters who are after 30 characters, but today, I found a column of names that are renamed as
All following columns are in single table only
surgey_pa_premedication_detail_dosa renamed to SURGEY_PA_PREMEDICATION_DETAIL (which is quiet right)
But
surgey_pa_premedication_detail_id renamed to SURGEY_PA_PREMEDICATION_DE_730
surgey_pa_premedication_detail_route renamed to SURGEY_PA_PREMEDICATION_DE_731
surgey_pa_premedication_detail_type renamed to SURGEY_PA_PREMEDICATION_DE_732
Thanx
Oracle was smarter than you think.
Could not truncate all the columns to 30characters because the first 30characters of each column are exactly the same. Truncation to 30characters would result in the same column name repeats another three times.
Thus, he executed the only for the first coumn truncate. For the following columns, he 26characters are truncated and added strings of 4 distinct characters.
You will need to rename the columns yourself to more meaningful names.

Change the name of the table/view to RPD.
Hello
I have a domain which has two points of view in it. The joints are given and have the subject area in the presentation layer. I created a few reports and they work fine. Now, we want to change the name of the views and do not want in the database. I changed the names in the presentation layer. I ran the created reports and they work fine. I have approach the right way? Did I modify them elsewhere? I don't want my reports to be affected in any way with the change of the view names. Please advice.Hello
When you change the name of table or a view in the presentation layer of the RPD, it will create aliases for that name .you may notice to double-click on the name of the table, alias tabIf you remove that alias name the report will be the effect on best practice is that do not delete aliases for name reports was changed from RPD table
the same scenario will apply for object zone rename also
Thank you

RadicYou must rename the table (using ALTER TABLE TableName RENAME to othername ;) before creating the MV.
You cannot have both existing with the same name in the same schema.What you see in the scheme of GQ, is that the 'picture' is the underlying table for the materialized view.
When you do a MY_MV CREATE MATERIALIZED VIEW AS...
Oracle creates two objects with the same name, we the MY_MV materialized view, and the other being the MY_MV table, which is the physical storage. {Don't forget that a materialized view is a way to get a physical representation of views.}In the schema QQ is what you
a. a real Table
or
b. a MV incorrectly deleted, resulting in the underlying Table always presents. -
Impossible to change the name of the Table in figures
I'm unable to change the title of a table, when I change the title name and press on enter it reverts to the original title. I tried to click away and save the document, but both go back to the original title. The only way to work is, it seems if the option a table a few times then start trying a new title.
This can happen when you have a table with the same name on the same sheet. Numbers of refuses to accept the name "double". Check the names of the tables on the al sheet again. One way to do that is to click the right part of the tab "" at the top with the sheet and inspect the table names in the drop-down menu that appears.

Using the name of the table to Insert variable
Hello
I'm trying to use a variable as the name of table to do an insert.
The name of the table where my datas have to be inserted is EVV_ + the Ref_var of data.
My code will be more explicit:
SELECT 'EVV_ ' | Ref_Equip
IN v_Ref_Equip
OF user.c_equip
WHERE clef_equip = v_clef_equip;
INSERT INTO 'user '. || v_Ref_Equip (Clef_var, Date1, value)
VALUES (v_clef_var, 18 May 01 ', 49, 156');
I can't find the proper syntax for inclusion in. I tried a lot of syntax, but not good.
So, how can I concatenate 'user.' + my v_Ref_Equip variable?
Thanks for the help

SQL how to use a variable and use the result as a reference for the name of the table
Hi all
I have new in the declaration of Oracle, sorry in advance if something is easy for you all. BTW, I have this scenario:
I have a table OL structured in this way:
Date - it contains dates, for example 11/01/2015
TableName - it contains strings, for example, OL1, OL2, OL3 and so on...
Then I have a different table, the name of these tables are of the same name in the table of the OL, so I have table table, OL1, OL2, OL3 table and so on. The structure of these tables is the same. And Yes.
table OL1
---------------------------------------------------------------
ID LAST NAME FIRST NAME PHONE
---------------------------------------------------------------
1 JOHN DOE 12345679
2 PAUL 111111122 TIBBS
table OL2
---------------------------------------------------------------
ID LAST NAME FIRST NAME PHONE
---------------------------------------------------------------
1 ANNA KRAIG (NULL)
NATHAN FRESHMANN 111111133 2
If the scenario is clear, I would like to retrieve the value (null), research in all the OL * tables by using the value of the OL table (tablename) max.
If I'm going to do these simple steps, I got the result:
Select max (TableName) OL
the result will be OL2
# I know not how to use the option set to avoid changing the table name in the sql statement all the time.
set mytable = 'OL2.
Select Name, family name
of & mytable
When the phone is null
Any idea?
Thank you very much in advance.
Hello
run immediately "select dt.log_id, obj.presentation_name, dl.begin_time
bulk collect into v_result_set
of ' | v_ol |' dt join internal ol_object obj on
DT.object_type_id = obj.object_type_id
inner join ol_chunk_log dl on
DT.log_id = DL.log_id
where dt.data_value is null';
dbms_output.put_line (v_ol);
end;
Correct the code such as:
run immediately "select dt.log_id, obj.presentation_name, dl.begin_time
of ' | v_ol |' dt join internal ol_object obj on
DT.object_type_id = obj.object_type_id
inner join ol_chunk_log dl on
DT.log_id = DL.log_id
where dt.data_value is null' bulk collect into v_result_set;
for i in v_result_set.first ... v_result_set. Last
loop
dbms_output.put_line ('LOG ID: ' | ) ( v_result_set.log_id (i)) ;
dbms_output.put_line (' NAME CLOSELY: ' |) v_result_set.presentation_name (i));
dbms_output.put_line (' START TIME: ' |) ( v_result_set.begin_time (i)) ;
end loop;
end;
Kind regards.

Find the name and the table constraint type based on the name of the field
I have a field name or a column with me... I want to find the name of the table is a primary key... Any request to make this work so that the running costs are low...
Currently, I mix dba_constraints and ALL_TAB_COLUMNS to get this... is possible to extract the data of a process cost effective single table/any other is appreciated
You must include the USER/ALL_CONSTRAINTS with USER/ALL_CONS_COLUMNS to achieve your desired results. For your specific condition, you can try this query.
Select constraint_name
column_name
de)
Select c.constraint_name
cc.column_name
count on column_count (c.constraint_name score) (cc.column_name)
from user_constraints c
Join user_cons_columns cc
on c.constraint_name = cc.constraint_name
where constraint_type = 'P '.
)
where column_name = 'EMPNO '.
and column_count = 1;
I used USER_CONSTRAINTS and USER_CONS_COLUMNS. If you use ALL or DBA dictionary table add join OWNER condition as well.

I have to use v_ename, as I don't know the name of the table.You need to use dynamic SQL statements if it is really an obligation. In the majority of cases, when people think that they need to code SQL dynamic, however, they attempt to conceal a more fundamental problem of design (often a data model that needs to be fixed). Since you haven't explained why you think you have need to use dynamic SQL statements, it is difficult to know if it's just adding more complexity to your environment.
If you know that there is always an ENAME column in which table is passed, you know that the ENAME column is always a VARCHAR2 (10), and the number of rows in the table is reasonably small
