mysql - mysql存储过程无法识别的数据类型错误

Question

我正在尝试运行此查询，但我一直在 C.id 附近收到无法识别的数据类型。我做错了什么？

CREATE PROCEDURE `proc`
BEGIN
CREATE TABLE 
  temp_table  
AS (
  SELECT UNIQUE(C.id) FROM table1AS C
                INNER JOIN table2 AS CA ON CA.college_id in (8192)
                INNER JOIN table3 AS CS ON CS.skill_id in (2744)
)

select * from temp_table

END

谢谢。

CREATE PROCEDURE `proc`()
BEGIN
      drop temporary table if exists temp_table;
      CREATE temporary TABLE temp_table  
      AS (
           SELECT distinct(C.id) FROM table1 AS C
           INNER JOIN table2 AS CA ON CA.college_id in (8192)
           INNER JOIN table3 AS CS ON CS.skill_id in (2744)
         );

      select * from temp_table;

END
