Question

我尝试使用此代码创建新的存储过程，该错误总是出现在我身上：

#count and sort the votes instaed of using collections
vote_count_dict = {}
for vote in votes:
    if vote in vote_count_dict:
        vote_count_dict[vote] += 1
    else:
        vote_count_dict[vote] = 1

vote_count = sorted(vote_count_dict.items(), key=lambda items: items[1], reverse=True)

MySQL说：文档

＃1064-您的SQL语法有错误；检查手册对应于您的MariaDB服务器版本，以使用正确的语法在第4行的“”附近

我使用以下代码创建存储过程：

    CREATE PROCEDURE `retriveData`() NOT DETERMINISTIC CONTAINS SQL SQL
    SECURITY DEFINER  BEGIN

    SET @sql = NULL

Answer 1

您忘记了定界符：

DELIMITER $$
CREATE PROCEDURE `retriveData`() NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER 
BEGIN

SET @sql = NULL;
SELECT
  GROUP_CONCAT(DISTINCT
    CONCAT(
      'MAX(IF(pa.item = ''',
      item,
      ''', pa.comValue, 0)) AS ',
      item
    )
  ) INTO @sql
FROM salaryStructureView;

SET @sql = CONCAT('SELECT p.id
                    , p.fullname
                    , p.salary, ', @sql, ' 
                   FROM employee p
                   LEFT JOIN salaryStructureView AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END
$$

我无法创建此过程
