What are the parameters required to use cursor in SQL statement?

To use a cursor in SQL, you need to define it and this requires the following parameters:

1. Cursor Name: This is the identifier that you will use to refer to the cursor in your SQL code.

2. SELECT Statement: This is the query that you want the cursor to execute. The result set of this query is what the cursor will be used to navigate.

3. INTO Clause: This is optional. If used, it specifies the variables that will store the data retrieved by the cursor.

4. FROM Clause: This specifies the table from which the data will be retrieved.

5. WHERE Clause: This is also optional. If used, it filters the records and fetches only those that fulfill the specified condition.

Here is a basic example of how to declare a cursor:

DECLARE cursor_name CURSOR FOR 
SELECT column_name 
FROM table_name 
WHERE condition;

After declaring the cursor, you can manipulate it using FETCH, OPEN, CLOSE, and DEALLOCATE statements.
