Exporting multiple tables in Oracle using the Expdp utility is a common task for database administrators and developers. Expdp is a command-line utility that allows you to export data from Oracle databases in a flexible and efficient way. By using Expdp, you can export multiple tables in a single operation, which can save you time and effort compared to exporting each table individually.
There are several steps involved in exporting multiple tables using Expdp. First, you need to create a parameter file that specifies the tables you want to export and the export options you want to use. You can specify the tables using their names or using wildcard characters to export tables based on certain criteria. Once you have created the parameter file, you can run the Expdp utility with the parameter file as an argument to export the tables.

Creating a Parameter File
To create a parameter file for exporting multiple tables using Expdp, you can use a text editor to define the export options and table names. The parameter file should include the following information:
1. The directory where the export dump file will be stored
2. The tables you want to export
3. The export options such as compression, parallelism, and encryption settings
Running Expdp with the Parameter File
Once you have created the parameter file, you can run the Expdp utility with the parameter file as an argument. The syntax for running Expdp with a parameter file is as follows:
expdp username/password@database directory=export_directory dumpfile=export_dump.dmp logfile=export_log.log tables=table1,table2,table3
By specifying the tables you want to export in the parameter file and running Expdp with the parameter file, you can export multiple tables in Oracle efficiently and easily. Expdp allows you to customize the export process to meet your specific requirements and save time compared to exporting tables individually.
