What is the statement for viewing the table structure in PL/SQL?

In PL/SQL, you can use the following SQL query statement to view the structure information of a table:

DESC table_name;

This command will display the structure of a table called table_name, including the names of each column, the data types, and constraints. Please replace table_name with the actual name of the table you want to view the structure of.

Alternatively, you can also use the following query to retrieve detailed information about the table structure:

SELECT column_name, data_type, data_length, nullable
FROM user_tab_columns
WHERE table_name = 'your_table_name';

This statement will provide detailed information on each column in the specified table (your_table_name), including the column name, data type, data length, and whether it can be null.
