图书归还界面图如图4.2所示
关于还书的Java代码：
//还书,参数为索取号
public int[] backBorrow(String sqh)
{
System.out.println("批量处理还书。。。。。");
String sql="";
String strBOOKID=ds.toString((String)toName("KJB2_KJXX_STORE","SQH","BOOKID",sqh));
String strNow = ds.getDateTime();
strNow = strNow.substring(0,10);
createStatement();
closeStm();
return result;
}
//根据所还书的索取号取得，此书的信息和是否过期等信息
public Hashtable checkBook(String sqh)
{
String sql="";
String strBOOKID=ds.toString((String)toName("KJB2_KJXX_STORE","SQH","BOOKID",sqh));
if(strBOOKID.equals("")) strBOOKID="-1";
String strBOOKCLASSID=ds.toString((String)toName("KJB2_KJXX_STORE","SQH","BOOKCLASSID",sqh));
if(strBOOKCLASSID.equals("")) strBOOKCLASSID="-1";
sql="select TITLE,AUTHOR,ISBN,CBSJ,DJ,PCJE,READERID,JYSJ,DQSJ "
+" from KJB2_KJXX_BOOK,KJB2_KJXX_JYB "
+" where KJB2_KJXX_BOOK.BOOKCLASSID="+strBOOKCLASSID+" and KJB2_KJXX_JYB.BOOKID="+strBOOKID+" and KJB2_KJXX_JYB.ZT='"+strZero+"'";
return searchOneData(sql);
}
归还的JSP代码：
调用的JavaBean为kjb2.library.bean.BorrowBean。
<jsp:useBean id="myBean" scope="page" class="kjb2.library.bean.BorrowBean"/>
界面的JSP代码：
<div align=center>
<hr>
<table width="100%" cellspacing=1 cellpadding=0 class="tbg" align=center>
<tr><td align="center" class=bgtable colspan=2 style="font:bold 20px"><br><br></td></tr>
</table>

<table width="100%" cellspacing=1 cellpadding=0 class="tbg">
