Import Data from Oracle Table: Step-by-Step Guide
To import all the data from a table, you can either use Oracle SQL Developer or the SQL*Loader tool. Below are examples of both methods:
- Utilizing Oracle SQL Developer:
- Open Oracle SQL Developer and connect to the database.
- Find the table you want to import data from in the left navigation bar.
- Right-click on the table and choose the option “Import Data”.
- Choose the file from which to import data in the pop-up dialog box.
- Click on “Next” and follow the instructions to complete the data import process.
- Utilizing the SQL*Loader tool:
- Create a data file containing the data to be imported, ensuring that the file format aligns with the columns of the target table.
- Create a control file that describes the format of the data file and how to load the data into the table.
- Open the command line window and use the following command to run the SQL*Loader tool to import data:
sqlldr username/password@database control=control_file.ctl data=data_file.dat
username is the database username, password is the password, database is the database name, control_file.ctl is the control file name, and data_file.dat is the data file name.
You can easily import all data from a table into an Oracle database using the two methods mentioned above.
