Question

cur.execute("UPDATE statdata(threemonthreturn, twomonthreturn, maxonemonthreturn, avgonemonthreturn, lastweekreutrn) values (?, ?, ?, ?, ?) WHERE companyid=%s; ", (str(threemonthreturn), str(twomonthreturn), str(maxonemonthreturn), str(avgonemonthreturn), str(lastweekreturn)) %p)

我遇到这行代码时遇到了困难。一切正常，除了companyid =％s和％p。我收到此错误： TypeError：％：＆＃39; tuple＆＃39;不支持的操作数类型和＆＃39; int＆＃39;

我有一个循环，其中p在范围内（1,72）：＆＃39;我已经在之前的几行代码中使用它而没有任何问题。（以下示例不会返回错误）

 for p in range(1,72):
    cur.execute("SELECT (((onemonthmax - threemonthmin) / (onemonthmax))*100) FROM statdata WHERE companyid = %s" %p)
    threemonthreturn =cur.fetchone()[0]

有人可以帮助我在我发布的第一行代码中放置companyid =％s，％p。

Answer 1

试试这个：

cur.execute("UPDATE statdata(threemonthreturn, twomonthreturn, maxonemonthreturn, avgonemonthreturn, lastweekreutrn) values (?, ?, ?, ?, ?) WHERE companyid=?; ", (str(threemonthreturn), str(twomonthreturn), str(maxonemonthreturn), str(avgonemonthreturn), str(lastweekreturn), p))

execute的第二个参数是元组：sqlite3 docs

使用python和sqlite的Tuple Int错误
