mysql - 在 WHERE 中更新多个值

Question

当满足这两个条件时，我需要更新数据库中的字段下面是我的代码
这是在 WHERE 条件下对一个值工作正常的查询

query2 = "UPDATE  Game_mygame 
          SET game_played = "+str(set_game_played)+" 
          WHERE home_teamID = "+str(i.home_teamID) 

但我需要匹配 WHERE 中的两个值，我正在尝试以下操作

query2 = "UPDATE  Game_mygame 
              SET game_played = "+str(set_game_played)+" 
              WHERE home_teamID = "+str(i.home_teamID)+ 
                    "AND away_teamID = "+str(i.away_teamID)  

但是这个给出了语法错误

请指出我哪里做错了

我认为第一个 WHERE 条件和 AND 之间没有空格。所以它会让你的查询像这样 WHERE home_teamID=xyzAND 而不是 WHERE home_teamID=xyz AND。所以你需要在 AND 之前多留一个空格(和你在 WHERE 之前给的一样)

query2 = "UPDATE  Game_mygame 
              SET game_played = "+str(set_game_played)+
              " WHERE home_teamID = "+str(i.home_teamID)+ 
              "AND away_teamID = "+str(i.away_teamID)
           ---^^--- Space is missing here

那么试试这个:

query2 = "UPDATE  Game_mygame 
              SET game_played = "+str(set_game_played)+
              " WHERE home_teamID = "+str(i.home_teamID)+ 
              " AND away_teamID = "+str(i.away_teamID)
