Question

我有一个以下SQL查询，如果输入了战斗机的名字或姓氏，则返回结果。如果还输入了名字和姓氏，我需要添加到此SQL查询以返回结果。这是查询：

SELECT distinct
'${searchT}' searchalp,
(SELECT COUNT(fighterId) FROM tblFighter where fighter_lastName like '${searchT}%' or fighter_firstName like '${searchT}%'  ) totalresults,
A.FighterID, 
A.Fighter_FirstName, 
A.Fighter_NickName, 
if (A.Fighter_Height > 0, 
CONCAT(FLOOR(A.Fighter_Height/12), '\' ', MOD(A.Fighter_Height,12), '"'), '') Fighter_Height_inch, 
A.Fighter_NormalWeight, 
if (A.Fighter_Reach > 0, CONCAT(ROUND(A.Fighter_Reach,0), '"') , '') Fighter_Reach, 
A.Fighter_Stance,
CONCAT('/fighter/',REPLACE(REPLACE(LCASE(A.Fighter_FirstName),' ','-'),'.',''),'/',REPLACE(LCASE(A.Fighter_LastName),' ','-'),'/',A.FighterID,'/') fighterURL,
(select count(*) from tblFight_Fighter where FighterID = A.FighterID and OutcomeID  = 1) fighterCareerWins, (select count(*) from tblFight_Fighter where FighterID = A.FighterID and OutcomeID  = 2) fighterCareerLosses, (select count(*) from tblFight_Fighter where FighterID = A.FighterID and OutcomeID  = 3) fighterCareerDraws,
fighter_lastName, FA.AccoladeDescription FROM tblFighter as A LEFT JOIN (SELECT FighterId, AccoladeDescription, AccoladeType
  FROM tblAccolade 
  JOIN tblEvent USING(EventID)
  JOIN (SELECT AccoladeID, Max(Event_Date) as MaxAccDate 
          FROM tblAccolade 
          JOIN tblEvent ON tblAccolade.EventID = tblEvent.EventID  
         WHERE AccoladeType = 'Belt' AND AccoladeDescription not like 'WEC%'
        GROUP BY AccoladeID) as tmpMaxAccDate ON tblAccolade.AccoladeID = tmpMaxAccDate.AccoladeID 
 WHERE Event_Date = MaxAccDate) as FA ON FA.FighterId = A.FighterId and FA.AccoladeType = 'Belt'  where A.fighter_lastName like '${searchT}%' or A.fighter_firstName like '${searchT}%' order by A.fighter_lastName ASC LIMIT ${stInd}, ${lstInd}

以下是将姓氏输入输入框时返回的内容示例：

Answer 1

在最后一行中，只需更改：

其中A.fighter_lastName喜欢'$ {searchT}％'或A.fighter_firstName喜欢'$ {searchT}％'

使用AND而不是OR

Answer 2

修改上面的第三行，使其中包含AND：

(SELECT COUNT(fighterId) FROM tblFighter where fighter_lastName like '${searchT}%' AND fighter_firstName like '${searchT}%'  ) totalresults,

那应该可以解决你的问题。

编辑：如果要修改查询以在一个字段“John Doe”中接受两个名称（因此您将搜索John的名字和Doe的姓氏），您将需要在该空间上拆分字符串并执行不同的WHERE子句。您可以尝试在现有WHERE子句中使用某些逻辑，也可以调用其他查询。但是，正如已经指出的那样，你在SQL语句中做了太多的业务逻辑。尝试将此处理带入代码的业务层。例如，您可以在代码中更容易地确定一个名称与您描述的两个名称相对应。然后你可以相应地修改一下这个电话。

如何在SQL查询中向WHERE子句添加其他条件？
