Question

我从Config properti文件中读取了B详细信息。现在我试图通过命令行参数传递和传递日期值来执行查询。我得到的是异常。请让我知道如何通过命令行参数将日期值传递给我的查询。 注意：我创建了包含所有库文件的excutalbel Jar文件。

输出：
java -jar CreateExcelFile1.jar 2014/01/20 2014/01/24

        Command line arguments length is 2
       Array index 0 value is 2014/01/20
      Array index 1 value is 2014/01/24
       Connection Successful
         java.sql.SQLException: ORA-01841: (full) year must be between -4713 and +9999, and not be 0

代码：

   public class CreateExcelFile extends DbConnection{
   public static void main(String[] args) {
  try{
System.out.println("Command line arguments length is " + args.length);
System.out.println("Array index 0 value is " + args[0]);
System.out.println("Array index 1 value is " + args[1]);
      Connection con = openConnection();
      PreparedStatement st=con.prepareStatement("Select a.oi_intervention_id ,a.oi_region,a.oi_mrn,b.opi_title, a.oi_rx_nb ,a.oi_store_id,to_char(a.oi_doc_crtd_dt,'dd-MON-yy') as SheetName,to_char(a.oi_doc_crtd_dt,'dd-MON-yy hh.mi.ss,FF AM TZH:TZM') as oi_doc_crtd_dt,to_char(a.oi_doc_expry_dt,'dd-MON-yy hh.mi.ss,FF AM TZH:TZM') as oi_doc_expry_dt from rxesbopcs.OPCS_INTERVENTION a ,rxesbopcs.opcs_program_info b where trunc(a.oi_doc_crtd_dt) BETWEEN TO_DATE ('args[0]', 'yyyy/mm/dd') AND TO_DATE ('args[1]', 'yyyy/mm/dd') and b.opi_program_id = a.oi_program_id order by a.oi_doc_crtd_dt",ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
    ResultSet rs=st.executeQuery();
     createXls(rs);
     System.out.println("Your excel file has been generated!");
      closeConnection(con);
    } catch ( Exception ex ) {
     System.out.println(ex);
     }
     }

Answer 1

我认为您需要将占位符放在要插入变量值的查询字符串中，例如而不是

 BETWEEN TO_DATE ('args[0]', 'yyyy/mm/dd')

你会把

 BETWEEN TO_DATE (?, 'yyyy/mm/dd')

然后在执行查询之前调用st.setString(1, args[0]);，对其他参数也类似。

您可能想要查看how to use prepared statements。

Answer 2

这不是PreparedStatements给定参数的方式（sql分布在几行以提高可读性）：

PreparedStatement st=con.prepareStatement("Select a.oi_intervention_id 
     ,a.oi_region,a.oi_mrn,b.opi_title, a.oi_rx_nb 
     ,a.oi_store_id,to_char(a.oi_doc_crtd_dt,'dd-MON-yy') as SheetName,
     to_char(a.oi_doc_crtd_dt,'dd-MON-yy hh.mi.ss,FF AM TZH:TZM') as oi_doc_crtd_dt,
     to_char(a.oi_doc_expry_dt,'dd-MON-yy hh.mi.ss,FF AM TZH:TZM') as oi_doc_expry_dt
  from rxesbopcs.OPCS_INTERVENTION a ,rxesbopcs.opcs_program_info b 
  where trunc(a.oi_doc_crtd_dt) BETWEEN TO_DATE (?, 'yyyy/mm/dd') AND 
      TO_DATE (?, 'yyyy/mm/dd') and b.opi_program_id = a.oi_program_id 
  order by a.oi_doc_crtd_dt",
    ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);

st.setString(1, args[0]);
st.setString(2, args[1]);
ResultSet rs=st.executeQuery();

Oracle tutorial on JDBC, including PreparedStatements非常好。

java.sql.SQLException：ORA-01841 :(完整）年份必须介于-4713和+9999之间，而不是0
