JDBC模板更新查询错误

我试图更新MySQL数据库使用JDBC模板更新查询春季JDBC模板更新查询错误

我的查询

String query = "update request set regions=?, requesttype=?, requestorigin=?, lineofbusiness=?, destinationenvironment=?, release=?, workrequest=?," 
        + " spmid=?, requestingteam=? where requestid="+request.getRequestId()+";"; 
      System.out.println(query); 
      Object[] params = {request.getRegions(), request.getRequestType(), request.getRequestOrigin(), 
        request.getLineOfBusiness(), 
        request.getDestinationEnvironment(), 
        request.getReleaseValue(), request.getWorkRequest(), 
        request.getSpmId(), request.getRequestingTeam() 
        }; 
      int[] types = { Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, 
        Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, 
        Types.VARCHAR }; 
      return jdbcTemplate.update(query, params, types);

当我运行此查询它显示了Mysql的语法错误。我无法找到
我错了。

答：我不是在DB很好..其实列版本是MySQL中的关键字..这就是为什么它被抛出的异常.. :) – Mahi

基于此错误消息：

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException：你有你的SQL语法错误;检查与您的MySQL服务器版本相对应的手册，以便在第1行的'release ='Search and Load'，workrequest ='zxZ'，spmid ='zxXZxZ'，requestsam ='Se'附近使用正确的语法

该问题似乎与release列有关。你确定该列存在吗？（正确拼写，在名称正确/小写）

UPDATE

事实证明，release是MySQL中的关键字。您需要引用使用反引号的那场，就像这样：

String query = "update request set regions=?, `release`=?, workrequest=?,"

不相关的问题，但就像你注入到设定值是多少？参数，在条件中为request.getRequestId()执行相同的操作，而不是字符串连接。这样它将以安全的方式注入。

也就是说，SQL字符串的结尾应该是这样的：

... where requestid= ?

，并在参数就像您设置，在params和types其他值添加request.getRequestId()。

检查是否加引号，解决问题吗？

"update `request` set `regions`=?, `requesttype`=?, `requestorigin`=?, `lineofbusiness`=?, `destinationenvironment`=?, `release`=?, `workrequest`=?," 
        + " `spmid`=?, `requestingteam`=? where `requestid`="

嘿它会工作:)，但很抱歉，我不能接受两个答案..反正实际的原因是由于使用关键字作为列名 – Mahi

没问题，你可以upvote答案:)。很好，你已经解决了你的问题。 :) –

为什么你还没有参数化查询中的requestId？假设的requestId为整数类型，代码可以被重新写入此：

String query = "update request set regions=?, requesttype=?, requestorigin=?, lineofbusiness=?, destinationenvironment=?, release=?, workrequest=?," 
        + " spmid=?, requestingteam=? where requestid=?"; 
System.out.println(query); 
Object[] params = {request.getRegions(), request.getRequestType(), request.getRequestOrigin(), 
     request.getLineOfBusiness(), 
     request.getDestinationEnvironment(), 
     request.getReleaseValue(), request.getWorkRequest(), 
     request.getSpmId(), request.getRequestingTeam(), 
     request.getRequestId()}; 
int[] types = { Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, 
     Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, 
     Types.VARCHAR, Types.INTEGER }; 
return jdbcTemplate.update(query, params, types);

让我知道这对你的作品。

仍然我得到相同的错误 – Mahi

request.getSpmId(), request.getRequestingTeam(),

您在Object数组末尾放置逗号。

不，我有一个元素添加request.getRequestingTeam（） – Mahi

后，但你已经给9个值9个占位符。我对吗？ – jcool

多数民众赞成在一个很好的..但这不是一个问题..我已经更新我的代码基于janos的建议..仍然会抛出异常 – Mahi
