I have a Oracle container DB SID orcl and pluggabel DB named pdb1. pdb1 has a table named customers. I am able to make the connection to database but I want to connect to a database table.
Below is the jdbc url string I am able to construct:
jdbc:oracle:thin:#localhost:1521/pdb1
I am using this string in a scripted sql connector. What parameter has to be included in this url string to connect to the table?
You don't connect to a table but to a database's schema.
The database is specified by the connection string and the schema by the user's name.
Refer to the Youtube videos and quickstart guides. For all resources related to Oracle JDBC, refer to www.oracle.com/jdbc

I'm starting to study Apache Kafka and Kafka Connect.
I'm trying to get data from a remote Oracle Database that my user only have read privilegies and can't list tables (i don't have permission to change that). To every query, i have to pass a dblink, but in the JDBC Connector, i didn't find a option to pass a dblink.
I can do the query if i pass a specific query on the connector configuration, but i want to fetch allot of tables and speficifying the query on the connector, would make me create allot of connectors.
There's a way to pass the dblink on the connector configuration or to the JDBC URL?
I am able to connect to Hive using hive-jdbc client and also using the beeline.Typical url is,
jdbc:hive2://hive_thrift_ip:10000/custom_schema;principal=hive/hive_thrift_ip#COMPANY.COM
Unfortunately the connection is always established to the 'default' schema of Hive , and it is not considering the configured schema name in the url. I use the org.apache.hive.jdbc.HiveDriver class
It always takes me to the tables of the default schema. Still I am able to access the tables from other schema using the schema name prefix to the tables, like custom_schema.test_table
Kindly let me know if I missed any property or configuration in the connection creation part which will help me in getting the session exclusively for the schema that configure in the url.
Many thanks.
I want to create a new database on an Oracle server via JDBC. I cannot seem to connect to the database without providing an SID: using a URL like jdbc:oracle:thin:#//[IP]:1521 results in an error of "ORA-12504, TNS:listener was not given the SID in CONNECT_DATA"
Alternatively, if I log into a specific SID, I can run most DDL commands except for CREATE DATABASE foo which fails with an error of "ORA-01100: database already mounted"
How am I supposed to create a database if I cannot connect to the server without specifying a specific database and cannot create a database if I am already logged into a specific database?
AFAIK creating a database needs an internal and direct connection which can only be done by logging in directly on the server (normally a user account called 'oracle').
One reason for that: users are stored in the database itself. No database = no user to connect to by an external client.
Please also note Justin's comment about oracles database schemas. This is probably what you are looking for
What you need are following commands:
CREATE TABLESPACE CREATE USER and few GRANT ... TO ... -- to have rights to connect and create objects, at least
I have a database stored at a server. I want to load test the server using jmeter.It requires a field called database url? Now what i am supposed to fill in that?
Also it is asking for jdbc driver class? What will be the values of these two?
JMeter uses JDBC.
What is your db ? Oracle, mysql ...
Each Db provides drivers you need to put in jmeter/lib folder.
For url each driver has a syntax, examples:
http://www.petefreitag.com/articles/jdbc_urls/
Then you need to add login/password
your database url should be -jdbc:mysql://localhost:3306/
database url is the host address of the database u can see that when you connect mysql from gui using SQl yog
is the database name that you have created in mysql
Your driver class should be -com.mysql.jdbc.driver
user name and password of the database
I have two different databases, one is in sql server and one is in oracle. i create a linked server between those two. how can i get data from oracle without the option "openquery".
Please help me out this.
You can create a connection link in oracle and then you can access the sql server database
