Pl-Sql User Connection - oracle

I've been starting oracle on my job. But i've been using MS all the time. Now i have problem on User-Shema structure. I tryed a create table with sql query, but table had been created in somewhere else then i wanted. (I've already created a user named LPA) I just wrote the query, and table is in the (GeneralDatabase) Tablespaces->Users->(Here). I want to create a table in LPA schema, under the table folder. I've been searching for it but i could'nt get it. So need some help please.
PS:I found that i need to connect with user, than write to query with TS_LPA(Thats my tablespace). But i also cant connect with the user LPA.(We can say this is my first problem)

In Oracle there is no "dbo" or default schema, in case that is what you are looking for. You must specify the target user account when you connect (log in) to the database, and that account will be used as the default schema for all of your subsequent actions. (This is similar to a home directory in Linux, where if I log in as williamr and create a file, it will belong to williamr and not some generic default account.)
In your case I suspect you are connecting as SYS or similar, in which case your table now belongs to SYS (or whoever you are connected as). You'll need to drop it and try again.
If you don't want to post the connect string you used to connect initially for some reason, then execute the following query to see your current schema:
select user, sys_context('userenv','current_schema') from dual;
(Normally user and sys_context('userenv','current_schema') will be the same, but worth double-checking.)
In PL/SQL Developer you can only issue connect commands from a Command window (not a SQL window). Alternatively you can use the 'log on' menu tool, or Session > Set Main Connection from the menu, or (best if you want to reuse it later) Tools > Define Connections, which has a 'Test...' button to validate a new connection. You'll need the username, password and database service name (not just username and password).

connect with LPA user.
specify the schema name before table name.
create table LPA.tbl_name(col1 datatype1,....);

Previous table appearing in new connection in Oracle database

Every time I create a new connection under the same common user on the SQL Developer tool it automatically copies the table(s) of the previous connection.
I am using Oracle Database 19c on the SQL developer tool.
In the below picture, there is a table having 2 columns.
In the below image, I have created a new connection, but it already has the previous tables.
troubleshooting steps I have followed so far -:
disconnected the previous connection: not solved
deleted the previous tables & connection: not solved
restarted SQL developer tool: not solved
deleted user and created again: this works but can't do it every time.
I have created a table using steps on this website: sqlserverguides
Please Advise :-)
The answer to your question here is that you are not doing what you think you are doing.
The objects newfirm and newtable are not tables, these are connections.
A connection needs a username and a password, a hostname to connect to, a port number, and a service name (or SID).
Once you are connected to a database server, all the "folders" you see under that connection are all related to the user used for the connection.
If you want to look at other users (be it sys or service users, or "people"), then you need to go to the folder "other users" in the same tree.
The screenshots you are showing there in your question only show 2 distinct connections (we don't know if the same details such as username + hostname were used) each with their own label/name (newfirm and newtable).
You can't "disconnect" a table, you also can't delete it .. you can drop it however which is likely what you meant.
In your screenshots, what you are pointing at and calling columns are actually tables.
Those things that you are pointing at and calling "previous table" and "new table" are not tables but connections (to a database server using a specific username).
You do not show any code you may be using, which would be useful.
If you want to drop a table (i.e. delete), you use the DROP command:
DROP TABLE user.tablename;
It is not possible for 2 tables with the same name to exist in the same schema (aka user).

How to solve ORA-65096 from Oracle SQL Developer?

I am trying to create a new user from Oracle SQL Developer. I made a connection with the user Sys and the password that I entered in the installation of Oracle Database XE 18c.
When creating the user I get the error ORA-65096, I have searched the internet and the solution I found is to write the following:
alter session set "_ORACLE_SCRIPT" = true;
However, I want to know if it is possible to create the new user without using any SQL statement or script and do it from the Oracle SQL Developer interface, do I have to login with a different user than Sys to create a new user? or what do I have to do? Could someone give me a detailed explanation please. I am learning how to use this database and I want to try to understand what I am doing.
oerr ora 65096
65096, 00000, "invalid common user or role name"
// *Cause: An attempt was made to create a common user or role with a name
// that was not valid for common users or roles. In addition to >the
// usual rules for user and role names, common user and role names
// must consist only of ASCII characters, and must contain the >prefix
// specified in common_user_prefix parameter.
// *Action: Specify a valid common user or role name.
This implies that you are connected to the root container instead of to a regular plug in database (pdb) where applications should be built. The solution for you is not to overrule setting to enable building an application in the root container but to connect to the pdb that has been made to host your application.
you can check the available pdb's by viewing v$pdbs. The special pdb cdb$root is as the name already tries to tell, the root container. show PDBS will give similar output.
Using alter session set container = [pdb_name]; can be used to switch to your container of choice where regular rules apply.
Even better is to directly connect to that pdb using sqlnet.

DB User account Password Reset from oracle apex

Iam creating an app to change the password of selected Db user account.When an user select a particular db name and user of the db then click submit button i should call procedures that changes the password of the db user.So guide me how to connect to selected db from oracle Apex and do it.
As far as I can tell, there are two ways to change someone's password:
connect as that user
connect as a privileged user (such a SYS)
and run such a command:
alter user scott identified by tiger;
As you'd want to do that for any database you have a access to, as well as every user in those databases, I doubt that you know their passwords so I guess that you'll connect as a privileged user to all those databases. Of course, you have to know their passwords.
One option would be to
create the same stored procedure (which will modify someone's password) in every database
it'll accept username and its new password
as alter table is DDL, you'll have to use dynamic SQL (execute immediate)
create database links to those databases in a schema you use to connect to your Apex application
depending on database you choose, call appropriate procedure via database link and pass chosen username and its new password. This might also require some kind of dynamic SQL, if you want to use different DB link name
I don't know which database version you use, but - have a look at 11g's Accessing and Modifying Information in Multiple Databases, especially "Running a Stored Procedure in a Remote Oracle Database" chapter for more info.

Using Oracle "Create User" command does not automatically create an associated schema

I'm just getting started with Oracle data export and import and things worked perfectly fine the first time around. But then I came back next day repeated the exact same steps on the same systems, but get ORA-01435: user does not exist error.
System Specs for all machines:
-OS: Windows 2012 R2 x64
-Oracle Server: Oracle 11G Express x64
Objective:
I'm exporting data from Oracle server 1 and importing to Oracle server 2.
Procedure:
Export data dump is successful from Oracle server 1.
but when importing the data dump on Oracle server 2, I follow this procedure:
-Stop IIS service
net stop WAS
Create Schema/user account and Grant privileges before import
net stop WAS
sqlplus / as sysdba;
CREATE user PIE1 identified by PASS1;
GRANT ALL PRIVILEGES TO PIE1;
GRANT IMP_FULL_DATABASE TO PIE1;
According to oracle, all goes well, but look at the first image bellow. In DBeaver, I can see that only the User account PIE1 has been created, but NO schema.
Oracle issue 1. User account created, but not the Schema
Question 1: According to Oracle, the command "Create User" IS supposed to also create an associated Schema. Anyone have an idea why this is no longer working for me? It worked once the night before.
I then continue the import procedure as follows:
imp PIE1/PASS1#xe file=c:\Backups\AVUSER2_6_7.dmp log=c:\Backups\import.log fromuser=AVUSER2_6_7 touser=PIE1;
But get the following error:
Oracle claims the User doesn't exist even though it does
Oracle claims the User doesn't exist even though it does. I repeated the entire procedure and even created an identical import/export user account and credentials, and this error still comes up.
Question 2: Any idea why Oracle "Can't find" a user account that's clearly in the database?
Additional Info:
Checked that my windows account is in admin group
Checked that my windows account is in ORA_DBA group
Opened all CMD prompt as Admin
As you implied, users and schemas as the same in Oracle, you can't have a user without a schema. No idea about DBeaver, but as there are other users that aren't listed under 'schemas' (according to your second image - ANONYMOUS, DIP, ...) that seems to be unrelated.
(Purely a guess, but perhaps the user you're connect as in DBeaver just doesn't have visibility of any objects owned by those users - maybe it only lists users it can see in all_objects, say. Pure speculation, but you could investigate that by looking at the data dictionary while connect through SQL*Plus as the same user. According to this old forum post, there is an option to hide empty schemas...)
The import is connecting successfully as PIE1 - you'd get a different error, ORA-01017, if it wasn't and you wouldn't see the 'Connected to...' banner or anything after that.
Your import command has a trailing semicolon that should not be there. The "importing ... objects into" message shows that it's trying to import into the PIE1; user and not the one you actually created, PIE1. Remove that semicolon and try again.
Incidentally, you can probably also remove the #xe TNS alias and stick to a local connection, assuming the environment is configured as it was whenyou ran SQL*Plus. You should also consider using datapump expdp/impdp rather than the legacy exp/imp.

Create database in oracle for manually created user

I want to create the user and the database within that user. But when I tried to create database its giving the warning message as
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-01100: database already mounted
Then I tried
STARTUP NOMOUNT;
Its giving the warning message for insufficient privileges even I have given all the permission to that particular user.
Can any one please help in finding the solution for this?
You don't create a database under a user in Oracle; I believe you're using terminology from another database poduct. The equivalent is a schema, which is a logical container for a group of objects. User and schema are essenentially synonymous in Oracle - when you create a user is automatically has its own schema.
You create the database once (which you already seem to have done, or had done for you), then create as many schemas/users as your application needs. You don't ever rerun the create database under normal circumstances - you certainly wouldn't as a normal user.
If you connect as that user you will be able to create tables, views, packages etc., assuming it has really been granted all the necessary privileges.
