How to get parameters properties from a program in oracle?

@orpha 

To get parameter properties from a program in Oracle, you can use the USER_ARGUMENTS data dictionary view. This view contains information about the arguments or parameters of stored procedures, functions, and packages in the database.

Here is a query you can use to get the parameter properties from a program in Oracle:

1
2
3

SELECT object_name, argument_name, data_type, in_out, data_length  
FROM user_arguments 
WHERE object_name = 'your_program_name';

Replace 'your_program_name' with the name of the program for which you want to get the parameter properties. This query will return the name, data type, direction (IN or OUT), and data length of the parameters of the specified program.

Additionally, you can also use the ALL_ARGUMENTS or DBA_ARGUMENTS data dictionary views if you do not have permission to access the USER_ARGUMENTS view. Just replace USER_ARGUMENTS with ALL_ARGUMENTS or DBA_ARGUMENTS in the query above.

Keep in mind that you may need the necessary privileges to access these data dictionary views and view the parameter properties of programs in the database.
