Before using an explicit cursor, you must declare it in the declaration section of a block or package as shown below: is the name of the cursor declared in the declaration section.

The number of variables must match the number of columns in the cursor select list.

If the SCROLL option is not specified in an ISO style DECLARE CURSOR statement, NEXT is the only FETCH option supported.

When you open a cursor, Oracle parses the query, binds variables, and executes the SQL statement.

Oracle also determines an execution plan, associates host variables and cursor parameters with the placeholders in the SQL statement, determines the result set, and sets the cursor to the first row in the result set.

If SCROLL is specified in an ISO style DECLARE CURSOR, all FETCH options are supported.
