Question

**每个人，因为我是IBatis的新手，我遇到了这个错误：我使用Ibatis oracle驱动程序和java连接到oracle数据库.Requirement是从oracle响应生成csv。

enter code here

package provider;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Reader;
import java.sql.SQLException;
import java.util.List;
import model.LMPeriod;
import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
public class JavaToIBatis {
public static void main(String[] args) throws SQLException, IOException {
    // TODO Auto-generated method stub

    Reader rd = Resources.getResourceAsReader("SqlMapConfig.xml");
      SqlMapClient smc = SqlMapClientBuilder.buildSqlMapClient(rd);
      /* This would read all records from the Employee table. */
      System.out.println("Going to read records.....");
      List<String> lst = (List<String>)smc.queryForList("LM.testing");
      BufferedWriter bw = new BufferedWriter(new FileWriter("test2.csv"));
      for(String str : lst){
         bw.write(str);
      }
      System.out.println("Records Read Successfully ");
   }

  }

enter code here
 <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" 
 "http://ibatis.apache.org/dtd/sql-map-2.dtd">

||', '|| FROM FROM XXSCM_BRM_GLRECON_REP
</select>   
</sqlMap>

 enter code here
 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config

     <property name="JDBC.Password" value="*******"/>

  </dataSource>
 </transactionManager>
 <sqlMap resource="OracleCrud.xml"/>

错误代码是

Answer 1

你错了两件事。

您已在OracleCrud.xml中提供了双重FROM。请删除一个。
你还在第二行给出了额外的分号[;]。

删除后，OracleCrud.xml将如下所示

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="LM">
    <select id="testing" resultClass="java.lang.String"> SELECT RCE_POST_TO_GL_FISCAL_QUARTER||', '|| RCE_POST_TO_GL_FISCAL_MONTH ||', '|| FROM XXSCM_BRM_GLRECON_REP </select>
</sqlMap>

对于xml检查，您可以使用xml美化网站：http://xmlbeautifier.com/

线程“main”中的异常com.ibatis.common.jdbc.exception.NestedSQLException
