I'm trying to use adonisjs as a backend. For oracle database i need to set nls variables when connection is established.
ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY.MM.DD'
How and where is it better to do it?

Ist there a way to change the default Sid "xe" which is Always used when adding a new Connection for "Oracle Sqldeveloper" ?
No, there is not.
But you can use an existing connection as a template.
Create a connection with your defaults.
Then, when it's time to create a new connection, edit your template, then save it with a NEW NAME. Presto-changeo, you have what you need/want.
I have an Oracle database installed on my computer, and I can connect to it with both Oracle Developer and SQL*Plus. Using either of these tools, is there any way to determine the connection string used for the existing connection?
In sql*plus, it stores the safe things (not the password) in _USER, _CONNECT_IDENTIFIER and _PRIVILEGE defined variables. By default, you can access them like:
prompt &_USER.#&_CONNECT_IDENTIFIER &_PRIVILEGE
In the example, how does SAS connect to oracle without an oracle hostname and port?
libname mydblib oracle user=testuser password=testpass path=hrdept_002;
http://support.sas.com/documentation/cdl/en/acreldb/63647/HTML/default/viewer.htm#a003113591.htm
I have experience with SAS connecting to other databases and I always needed to supply a host and port
The documentation states
PATH= specifies an alias for the database specification, which SQL*Net requires
The alias is set up in your SAS hosting environment prior to running SAS. Typically the set up occurs in a tnsnames.ora configuration file. Which config file to select may also be controlled by other environment variables.
I'm new to Oracle SQL and so I'm quite troubled with this problem. I have Oracle 11g, SQL Developer, sqlplus installed in my machine. I have created the following two connections in sqldeveloper:
Connection Name Username Password
dbms SYSTEM maharshi
test SYSTEM maharshi
The connection type is basic, role is default, Hostname, port and SID are all default values. i.e. localhost, 1521, xe respectively.
Now, when we select a specific database and execute statements in it's corresponding worksheet, the effect takes place w.r.t that particular connection only. i.e. if we create a table in the sql worksheet in sqldeveloper of dbms connection, then a table is shown in the dbms connection only and not in that of test connection.
But, if I login via SQLPlus as below:
sqlplus SYSTEM/maharshi
And thereafter I execute the table creation, which connection will it affect? If I execute the statement, which connection will get affected(dbms or test)? Suppose I want to create a table in the dbms connection only via sqlplus, how to do that?
I am not sure if I understood you correctly, so I apologize in advance.
It does not matter what is your Connection Name in SQL Developer. What matters is a Username. You work in the schema of a user that you are connected to. In your case both of your connections are from the user SYSTEM. So if you create a table in the dbms connection you will have access to this table from the test connection. The same goes for the sqlplus connection.
Bottom line: your table will be visible accross all your connections.
I need connect to Oracle database use jdbc driver. I look on structure URL string to connect and not see, where i xan set charSet to connect.
Help me please.
You shouldn't need to set the character set. Java uses Unicode internally and the data from the database should be converted from the database character set to UTF-16 by the JDBC driver.
