使用 pymysql 的 execute 方法执行 SQL 语句

SQL 语句如下：
SET @days := 10;
SELECT @days as 'days';

报语法错误
(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT @days AS 'days'' at line 4")

这个 SQL 语句在 navicat 上是可以执行的

有大佬帮忙指点迷津吗

贴下你的 py 代码应该，
如上 sql 直接到 mysql 执行是没问题的
@smallpython 设置个运行时全局变量而已

@tmackan
代码是这样的：
（我觉得不是 py 代码的问题，因为其他的 SQL 语句是可以运行的，可能是这个 SQL 里面有两个分号导致的）
sql ="""
SET @days := 10;
SELECT @days as 'days';
"""
cOnn= pymysql.connect(host, port,user,password,database,charset="utf8")
cur = conn.cursor()
cur.execute(sql)
conn.commit()
