Question

原代码：
public boolean OutProTable(String compName) throws SQLException {
    boolean Isout = false;
    long SAFETYID = 0,USERID = 0;
    String PROBCONTENT ="",REMARKS = "",COMPANYNAME ="", CREATION_TIME = "",SAF_FLAG = "";
    String SQL = "delete from SAFETYPROBLEM where COMPANYNAME='" + compName.trim()+
    "'";
    System.out.println("SQL = "+SQL);
    pool.executeUpdate(SQL);
    sql = "select * from SAFETYPROBLEM where COMPANYNAME='" + compName.trim() + "'";
    System.out.println("sql = "+sql);
    rs = db.executeQuery(sql);
    while (rs.next()) {
      System.out.println("111111");
      SAFETYID = rs.getLong("SAFETYID");
      System.out.println("SAFETYID = "+SAFETYID);
      USERID = rs.getLong("USERID");
      PROBCONTENT = rs.getString("PROBCONTENT").trim();
      REMARKS = rs.getString("REMARKS");
      COMPANYNAME = rs.getString("COMPANYNAME");
      CREATION_TIME = rs.getString("CREATION_TIME");
      SAF_FLAG = rs.getString("SAF_FLAG");
      sql1 = "insert into SAFETYPROBLEM ("+
          "SAFETYID,"+
          "PROBCONTENT,"+
          "REMARKS,"+
          "COMPANYNAME,"+
          "USERID,"+
          "CREATION_TIME,"+
          "SAF_FLAG"+
          ")values("
          +SAFETYID + ",'" + PROBCONTENT + "'," +
          REMARKS + "','" + COMPANYNAME+ "'," +
          USERID + ",'" + CREATION_TIME + "','" +
         SAF_FLAG + "')";
      pool.executeUpdate(sql1);
      pool.close();
      Isout = true;
    }
    rs.close();
    db.close();
    return Isout;
  }调用这个方法后报java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] 语法错误 (操作
符丢失) 在查询表达式 '2','工区1                                   ',60,'2005-06-
13 04:42:52','4.10.1                        ')' 中。　这个错
这是为什么呀
