The PL/SQL FETCH command is used to retrieve rows one at a time from a result set returned by a cursor. The row is then stored into variables or fields in the program. Here are the steps to understand how it works:

1. Declare the Cursor: First, you need to declare a cursor using the DECLARE keyword. The cursor is associated with a SELECT statement that retrieves some data from the database.

2. Open the Cursor: After declaring the cursor, you need to open it. The OPEN statement executes the SQL query associated with the cursor, identifies the result set, and positions the cursor at the beginning of the result set.

3. Fetch the Cursor: Now, you can retrieve the rows from the result set one at a time using the FETCH statement. Each FETCH statement retrieves the next row in the result set and stores the values in target variables or fields.

4. Close the Cursor: After retrieving all the rows, you should close the cursor using the CLOSE statement. This releases the memory associated with it.

Remember, the FETCH command only retrieves the next single row. If you want to fetch all rows, you need to use a loop.
