使用JSP對(duì)數(shù)據(jù)庫(kù)進(jìn)行增刪改查

使用JSP對(duì)數(shù)據(jù)庫(kù)進(jìn)行增刪改查注意紅體字!首先，打開sqlserver2005,輸入用戶名(我用的登錄名是paiipan)密碼(我設(shè)置的是123)。先建個(gè)表student,Createtablestu(idnumber(30),namevarchar(50),agenumber(30),sexvarchar(30),majorvarchar(50));打開MyEclipse,新建一個(gè)新項(xiàng)目，讓后將iiidex.jsp刪除，然后在webRoot文件中新建以卞幾個(gè)jsp文件。iiidex.jsp<%@pagelanguage=HjavaMuupon=njava.util.*"pageEncodmg=,,GB2312H%><%Strmgpath=request.getContextPath();String basePath =iequest.getSchemeO+H：//,,+iequest.getServreiName()+n:H+request.getServreiPort()-rpatli+'7M;%><litnil><liead><baseluef=H<%=basePath%>H>＜曲》輸入學(xué)生信息界面＜/title＞<metahttp-equhT=HpragniaMcontent=nno-cacheH><metahttp-equhT=Hcache-controlncontent=Mno-cacheH><metahttp-equivT=HexpiiesMcontent=n0M><metahttp-equhT=nkeywordsncontent=nkevword1.keyword2.keyword3M><metahttp-equhT=ndesciiptionncontent=MTlusismypage"><scripttype=ntext.-javasci!ptn">fiinctionvalidate()varid=document.forms[0].id.value;varname=document.fonns[0].name.value;varage=document.fdrnis[0].age.value;varniajor=document.forms[0].major,value;if(id<=0){alertC學(xué)號(hào)不能為空，請(qǐng)輸入學(xué)號(hào)！returnfalse;}elseif(name.length<=0){alei1("姓名不能為空，請(qǐng)輸入姓名！”)；returnfalse;}elseif(age<=0){alert("請(qǐng)輸入合法年齡！”)；returnfalse;}elseif(major.length<=0){alert(“專業(yè)不能為空，請(qǐng)輸入所學(xué)專業(yè)！”);returnfalse;returntme;}}</script></head><bodv>J<bi><center><h2>學(xué)生信息輸入</h2xhr><formaction=Minsert.jspHmethod=npostnid=nfbrmnonSubinit="validate。"><h4>學(xué)號(hào):<iiiputtvpe=ntextMname=HidHclass=H{required:tnie}',></input><br></h4><h4>姓名:<iiiputtvpe=ntextMname=HnameM></mput><bf></li4><h4>年齡：<iiiputtvpe=ntextMname=HageH></mput><br></h4><h4>性別：<iiiputtype=nradioHname=nsexMvalue=n男">男<mputtype=HradioMnaine=nsexnvalue=H女”a女<br></h4><h4>專業(yè)：<iiiputtvpe=ntextMname=Hniajoi"></mput><br></h4><inputtype=Hsubinitnvalue=M提交"/></form><aluef=layout.jsp>查看己輸入信息</a></center></body></hmil>insert.jsp<%@pagelanguage=HjavaHimport-java-util.*"pageEncoding=Hgb2312ft%><%@pageinipoit=Hjava.sql.*n%><%Stringpath=request.getContextPath();String basePath =ieqi代st.getSch亡meO+m//”+eqi】est?g&ServerNamq)+"J+i:eqMSt?getSirveTPort()+patli+”/”；%><litnil><liead><baseluef=H<%=basePath%>H><title>插入學(xué)生信息</title><metahttp-equivT=HpragniaMcontent=nno-cacheH><metahttp-equivT=ncache-controlncontent=Mno-cacheH><metahttp-equivT=nexpiiesMcontent=n0H><metahttp-equivT=nkeywordsHcontent=nkevword1,keyword2.keyword3M><metahttp-equivT=ndesciiptionncontent=MTlusismypage"></head><bodv>J<%iequest.setCharacterEncodmg(Mgb2312n);Stringid=request.getPaiameter(nidH);Stringnaiiie=request.getPaiainetei(Mnamen);System.out.piiiitlii(naiiie);Stringage=iequest.getParameter(MageH);Stringsex=request.getParameter(Msexn);Stringmajor=request.getPaiameter(Mmajorn);Connectioncoiiii=null:Statementstat=null;Class.fbrNaiiie(ncom.nuciosoft.sqlseiveLjdbc.SQLServreiDrivein);Stringurl=Hjdbc:sqlsenre匚〃localhost:1433;DaUibaseName=Tesf';Stunguser=”panpan“； (我的數(shù)據(jù)庫(kù)登錄名是我自己新建的，你可以根據(jù)你自己的Stringpasswoid="123,';登錄名和密碼進(jìn)行修改)comi=DriverManagei-.getComiection(urLuser,password);stat=comi.createStatement();iiit is=stat.executeUpdate(nmsert mtostu(,age,sex,major)values(M+id+H/,,+name+'H/,+age+n,,n+sex+H7H+major+n,)H);%><center><br><aluef=iiidex.jspa返回信息輸入頁(yè)面</a> <aluef=layout.jsp>進(jìn)入信息查詢頁(yè)jfi</a></center><%if(stat!=null){stat.closeQ;}if(comi!=null){coim.close();}%></body></hmil>layout.jsp<%@pagelanguage=HjavaHuupon=Mjava.util.*"pageEncodmg=Hgb2312H%><%@pageinipoit=Hjava.sql.*n%><%Stringpath=request.getContextPathQ;String basePathiequest.getSchemeO+H：//,,+iequest.getServreiName()+n:H+request.getServrerPort()-rpatli+'7M;%><litnil><liead><basehief=H<%=basePath%>H><Mle>學(xué)生信息v/htle><metahttp-equivT=HpragniaMcontent=nno-cacheH><metahttp-equivT=ncache-controlncontent=Mno-cacheH><metahttp-equivT=nexpiiesMcontent=n0H><metahttp-equivT=nkeywordsncontent=nkevword1,keyword2.keyword3M><metahttp-equivT=ndescriptionncontent=MTlusismypage"></head><bodv>J<%response.setCharacterEncoding(Hgb2312M);iequest.setCharacterEncodmg(Mgb2312H);Stringid=request.getPaiameter(nidH);Strmgnaiiie=request.getPaiaiiietei(HnameH);Stringage=iequest.getParameter(MageH);Stringsex=request.getParameter(MsexH);Stringmajor=request.getPaiameter(MmajorH);Connectioncoiiii=null:Statementstat=null;ResultSetrs=null;Class.fbiNaiiie(ncom.niiciosoft.sqlseiver.jdbc.SQLServreiDrivein);Stringuii=*jdbc:sqlsenre匚//localhosrl433;DatabasuName=Tesf；Strmgusei-="panpaii'\ (我的數(shù)據(jù)庫(kù)登錄名是我自己新建的，你可以根據(jù)你自己的Stringpassword=n123M;
