create lot_1 cursor for select * from temp_minj1.lot 

Answer 1

在Oracle，SQL語法是這樣的：

DECLARE 
    my_emp_id  NUMBER(6);  -- variable for employee_id 
    my_job_id  VARCHAR2(10); -- variable for job_id 
    my_sal  NUMBER(8,2); -- variable for salary 
    CURSOR c1 IS SELECT employee_id, job_id, salary FROM employees 
     WHERE salary > 2000; 
    my_dept departments%ROWTYPE; -- variable for departments row 
    CURSOR c2 RETURN departments%ROWTYPE IS 
     SELECT * FROM departments WHERE department_id = 110;
