I'm using latest DBeaver community edition on Oracle DB,
When creating insert into statement
INSERT INTO TABLEA
The autocomplete suggest WHERE although there's no usage/meaning in INSERT INTO syntax
Also inside columns INSERT INTO TABLEA (
Why WHERE is suggested? is it DBeaver bug?
also INTO isn't suggested after INSERT
EDIT
Should be fixed in 22.0.2 milestone
Opened a DBeaver issue which will be fixed on 21.3.0 milestone
Remove where keyword suggession on Oracle insert into statement #13879

I want Oracle SQL Developer to create a SELECT statement "automatically" for the table that are in databse, I want the table query for extraction and so that I do not have to type for all.
Let me guess: you want SQL Developer to create a SELECT statement "automatically". If so, then drag table into the editor and choose an option:
Result:
SELECT
ename,
job,
sal,
comm
FROM
bonus;
As part of my project, new columns are introduced in many tables. I wanted to find out the date in which this columns are introduced. Is there a way I can query the date of insertion of all the columns in a specific table in Oracle SQL Developer 3.0.04.
You can try to use the last_ddl_time object from the dba_objects table.
I am looking for a tool or online resource which when given a PL/SQL code gives information about tables on which insert , select , update and delete are performed.
e.g:
TABLE SELECT INSERT UPDATE DELETE
v_empl Yes Yes No No
Should it be static i.e. source based or dynamic(based on workload)?
Look at this grammar for PL/SQL:
https://github.com/patrick133t/PLSQL
And this SQL grammar:
https://github.com/porcelli/plsql-parser
With some tweaking you will be able to extract all SQL statements from PL/SQL code and all table references from all SQL statements.
Also look at DBA_DEPENDENCIES view. Oracle maintains similar information internally.
Also note that there are statements like insert "from" select or updatable joins, so sometimes it is non-trivial to identify source and target table.
In SQL Server one could do something like the following
declare #t as table(id int)
insert into #t values(1)
insert into #t values(2)
delete from #t where id=1
Is there an equivalence of this in Oracle without creating a physical table. Now, I used to create physical table to do this and delete later.
I have gone to this links How to create a temporary table in Oracle but that's 2010 and the reference link mentioned Oracle 8i. Is this still the situation with Oracle 10g and 11g? Another link I have visited is Constructing a temporary table in Oracle SQL
Thanks
CREATE GLOBAL TEMPORARY TABLE admin_work_area
(startdate DATE,
enddate DATE,
class CHAR(20))
ON COMMIT DELETE ROWS;
This statement creates a temporary table that is transaction specific.
For details use below link:
http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables003.htm#i1006400
In most cases you do not need it. In Oracle when you need temporary table then "your design is wrong". Do not try to rewrite MS SQL pattern into Oracle which exact wording. Where you use temporary table in MS SQL you use in Oracle CTE(nested subquery, query factoring) a CURSOR or some PL/SQL construct.
The temporary table is not what you need. It's just a tool you use to achieve some goal. In Oracle you should use other tools.
Use an Associative Array :)
declare
type temp_rec is record(v integer);
type temp_table is table of temp_rev indexed by pls_integer;
my_temp_table temp_table;
begin
-- Here you can do do your stuff :)
end

I am trying to export data in oracle 11g
exp user/password file=dump.dmp tables = (table1)
via sqlplus.
And i get the following error:
About to export specified tables via Conventional Path ...
EXP-00011: USER.TABLE1 does not exist Export terminated
successfully with warnings.
But when i check who is the owner of this table:
SELECT owner, table_name from dba_tables where table_name = 'TABLE1';
I get that the owner of TABLE1 is USER
What should i do to export this table?
UPDATE
Actually, i found a solution. I hope it will help someone else.
Since version 11g Oracle has introduced new feature that is called deferred segment creation. Thus oracle doesn't create table segment if there are now rows in it. So i recreated my table with option 'segment creation immediate'
Actually, i found a solution. I hope it will help someone else. Since version 11g Oracle has introduced new feature that is called deferred segment creation. Thus oracle doesn't create table segment if there are no rows in it. And my table didn't contain any data. So i recreated my table with option 'segment creation immediate'
The solution was found here. There are more options how to fix the problem and an explanation why this thing happens to be in oracle 11g. :)
In addition to the posted answer from Olivia i would like to add some code:
SELECT 'alter table ' || table_name || ' allocate extent;'
from dba_tables where SEGMENT_CREATED = 'NO';
Execute the output and exp again. Your schema will be exported including empty tables.
EDIT:
similar question here, maybe you'll find your solution there.
Change this:
exp user/password file=dump.dmp tables = (table1);
to this:
exp user/password tables = (table1) file=dump.dmp;
You Can Use below query to take table level export from specific user.
exp user/password file=dump.dmp tables = user.table1
