Oracle Database is a powerful and popular relational database management system. It is used by many organizations to store and manage their data. In this tutorial, we will learn how to insert, update, and delete data in Oracle Database.
The first step in working with Oracle Database is to connect to the database. This can be done using the Oracle Database command line interface (CLI) or using a graphical user interface (GUI) such as Oracle SQL Developer. To connect to the database using the CLI, you will need to provide the username and password for the database.
Once you have connected to the database, you can begin working with the data. The following example shows how to connect to the Oracle Database using the CLI:
sqlplus username/password@database_nameOnce you have connected to the database, you can begin working with the data.
Once you have connected to the database, you can begin working with the data. The first step is to create a SQL statement. This statement will be used to insert, update, or delete data in the database. The following example shows how to create a SQL statement to insert data into the database:
INSERT INTO table_name (column_1, column_2, ...) VALUES (value_1, value_2, ...);The above statement will insert a new row into the table with the specified values for each column.
Once you have created the SQL statement, you can execute it. This can be done using the Oracle Database command line interface (CLI) or using a graphical user interface (GUI) such as Oracle SQL Developer. The following example shows how to execute a SQL statement using the CLI:
sqlplus username/password@database_name @sql_statement.sqlThe above command will execute the SQL statement in the file sql_statement.sql.
Once the SQL statement has been executed, the changes must be committed to the database. This can be done using the Oracle Database command line interface (CLI) or using a graphical user interface (GUI) such as Oracle SQL Developer. The following example shows how to commit the changes using the CLI:
COMMIT;The above command will commit the changes to the database.
Once the changes have been committed, the connection to the database must be closed. This can be done using the Oracle Database command line interface (CLI) or using a graphical user interface (GUI) such as Oracle SQL Developer. The following example shows how to close the connection using the CLI:
EXIT;The above command will close the connection to the database.
In this tutorial, we have learned how to insert, update, and delete data in Oracle Database. We have seen how to connect to the database, create a SQL statement, execute the statement, commit the changes, and close the connection. We hope this tutorial has been helpful in understanding how to work with Oracle Database.
