临时表（XXX）已存在于会话中

Question

我尝试填充临时表但是我收到以下错误：

SQL Error (-958) : Temp table (temp_table11) already exists in session.

---

CREATE TEMP TABLE temp_table11
  ( emp_num int);


SELECT emp_num FROM hrgetd INTO  temp_table11
WHERE( emp_num = v_emp_num AND calc_year = p_calc_year)

Answer 1

您正在尝试在select语句中再次创建表，请尝试此

CREATE TEMP TABLE temp_table11
  ( emp_num int);

INSERT INTO temp_table11
SELECT emp_num FROM hrgetd
WHERE( emp_num = v_emp_num AND calc_year = p_calc_year)

Answer 2

使用SELECT INTO时，无需声明表格

SELECT emp_num FROM hrgetd INTO  temp_table11
WHERE( emp_num = v_emp_num AND calc_year = p_calc_year)
