JDBC模板更新查詢錯誤

我試圖更新MySQL數據庫使用JDBC模板更新查詢春季JDBC模板更新查詢錯誤

我的查詢

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);

當我運行此查詢它顯示了Mysql的語法錯誤。我無法找到
我錯了。

答：我不是在DB很好..其實列版本是MySQL中的關鍵字..這就是爲什麼它被拋出的異常.. :) – Mahi

基於此錯誤消息：

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException：你有你的SQL語法錯誤;檢查與您的MySQL服務器版本相對應的手冊，以便在第1行的'release ='Search and Load'，workrequest ='zxZ'，spmid ='zxXZxZ'，requestsam ='Se'附近使用正確的語法

該問題似乎與release列有關。你確定該列存在嗎？（正確拼寫，在名稱正確/小寫）

UPDATE

事實證明，release是MySQL中的關鍵字。您需要引用使用反引號的那場，就像這樣：

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

不相關的問題，但就像你注入到設定值是多少？參數，在條件中爲request.getRequestId()執行相同的操作，而不是字符串連接。這樣它將以安全的方式注入。

也就是說，SQL字符串的結尾應該是這樣的：

... where requestid= ?

，並在參數就像您設置，在params和types其他值添加request.getRequestId()。

檢查是否加引號，解決問題嗎？

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

嘿它會工作:)，但很抱歉，我不能接受兩個答案..反正實際的原因是由於使用關鍵字作爲列名 – Mahi

沒問題，你可以upvote答案:)。很好，你已經解決了你的問題。 :) –

爲什麼你還沒有參數化查詢中的requestId？假設的requestId爲整數類型，代碼可以被重新寫入此：

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);

讓我知道這對你的作品。

仍然我得到相同的錯誤 – Mahi

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

您在Object數組末尾放置逗號。

不，我有一個元素添加request.getRequestingTeam（） – Mahi

後，但你已經給9個值9個佔位符。我對嗎？ – jcool

多數民衆贊成在一個很好的..但這不是一個問題..我已經更新我的代碼基於janos的建議..仍然會拋出異常 – Mahi
