ASP代码用的操作access数据库命令语法大全哪里有

Question

ASP源代码里面的 诸如 Dim 。 oConn.execute 属于哪一类，哪里有详细的教材
如果买书的话，到底买什么书？？

Answer 1

《ASP编程大全》在此谁敢不从！
1.提取字段列表
//<%
Set cn=Server.CreateObject("ADODB.Connection")
cn.Open "Provider=SQLOLEDB;Data Source=localhost;" & _
"Initial Catalog=pubs;User ID=sa;Password="
Set rs=cn.Execute("Select * from authors")
While Not rs.EOF
Response.Write rs("au_fname")
rs.MoveNext
Wend
rs.Close
cn.Close
//%>

2.返回数据集函数
Public Function GetData() As ADODB.Recordset
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Set cn=CreateObject("ADODB.Connection")
cn.Open "Provider=SQLOLEDB;Data Source=localhost;" & _
"Initial Catalog=pubs;User ID=sa;Password="
Set rs=CreateObject("ADODB.Connection")
rs.LockType=adLockBatchOptimistic
rs.CursorLocation=adUseClient
rs.CursorType=adOpenStatic
rs.Open "Select * from authors",cn
Set rs.ActiveConnection=Nothing
cn.Close
Set cn=Nothing
Set GetData=rs
End Function

3.从XML文件中读取数据
<!-- Metadata type="typelib" file="c:\program files\common files\system\ado\msado15.dll"-->
<%
'response.write admoderead & " " & adopenstreamfromurl
'response.End()
set rs = server.CreateObject("adodb.recordset")
Set stmData = Server.CreateObject("ADODB.Stream")
stmData.Charset="gb2312"'这一句很重要，否则会报一个错误。Recordset cannot be created from the specified source. The source file or stream must contain Recordset data in XML or ADTG format.移山祝大家好运^_^

xmbm = request.QueryString("xmbm")
if xmbm = "" then xmbm = "110100001"
Dim result
dim xml, XMLlength
Set DCOMServer = CreateObject("RemObjects.SDK.COMServer")
DCOMServer.MessageType = "TROBINMessage"
DCOMServer.ChannelType = "TROWinInetHTTPChannel"
DCOMServer.SetChannelProperty "TargetURL", "http://192.168.1.119:8089/BIN"
Set DCOMService = DCOMServer.CreateService("DCOMService")
xml = cstr("<?xml version="&chr(34)&"1.0"&chr(34)&" encoding="&chr(34)&"gb2312"&chr(34)&" ?>" & chr(13)&chr(10))
xml = xml & cstr(DCOMService.GetItem(xmbm))'用于生成XML主体的DCOM服务，实际中请灵活运用。
Set MegaDemoService = nothing
'response.write xml
'response.End()
stmData.Open
stmData.WriteText xml
stmData.SetEOS
'stmData.SaveToFile server.MapPath("zzzz"&session.SessionID&".xml"),2
'response.End()
stmData.Position = 0
rs.open stmData
if not rs.eof then
response.write "<table border = 1 cellpadding=5 cellspacing=0 bordercolor=black style='border-collapse:collapse;'><tr bgcolor='#ddddeee'>"
for each fld in rs.fields
response.write "<td>" & fld.name & "</td>"
next
response.write "</tr>"
do while not rs.eof
response.write "<tr>"
for each fld in rs.fields
response.write "<td>" & fld.value & "</td>"
next
response.write "</tr>"
rs.movenext
loop
end if
rs.close
set rs = nothing
%>

4.把数据写入XML文件
<%
class autoXML
Private xmldoc
Private xmlfile

Sub Class_Initialize()
set xmldoc = Server.CreateObject("Microsoft.XMLDOM")
xmldoc.async = fasle
End Sub

Sub Class_Terminate()
set xmldoc = Nothing
End Sub

Public Property Let filePath(str)
xmlfile = str
End Property

Sub getRs(rs)
dim xmlhead
dim pNode,sNode
dim aNode,tNode
dim tableName
dim rf
dim i
set xmlhead = xmldoc.createProcessingInstruction("xml","version=""1.0"" encoding=""GB2312""")
xmldoc.insertBefore xmlhead,xmldoc.childNodes(0)
tableName = split(rs.Source,chr(32))
set pNode = xmldoc.CreateElement(tableName(3))
xmldoc.appendChild pNode
redim aNode(rs.Fields.Count-1)
do while not rs.eof
set sNode = xmldoc.CreateElement(tableName(3)&"list")
pNode.appendChild sNode
for i=0 to rs.Fields.Count-1
if rs.Fields(i).Name=tableName(3) then
tNode = rs.Fields(i).Name&"Child"
else
tNode = rs.Fields(i).Name
end if
set aNode(i) = xmldoc.CreateElement(tNode)
sNode.appendChild aNode(i)
if rs.Fields(i).value<>"" then
aNode(i).text = rs.Fields(i).value
end if
next
rs.movenext
loop
End Sub

Function saveFile()
on error resume next
xmldoc.save xmlfile
saveFile = (err.number=0)
End Function
End Class
%>
调用，把调用recordset就可以了。
<%
dim conn
set conn = Server.CreateObject("adodb.connection")
conn.open "Provider=Microsoft.jet.oledb.4.0;data source="&Server.MapPath("db.mdb")
dim rs,sql
set rs = Server.CreateObject("adodb.recordset")
sql = "select * from news"
rs.Open sql,conn,3,2

dim ixml
dim xf
set ixml = new autoXML
xf = "test.xml"
ixml.filePath = Server.MapPath(xf)
ixml.getRs(rs)
if ixml.saveFile() then
response.write "<a href=""" & Server.URLEncode(xf) & """>保存完毕</a>"
else
response.write "保存文件错误"
end if
set ixml = Nothing
rs.close
set rs = Nothing
%>

ors.Close()
rs.movenext()
}while(!(rs.eof||rs.bof))
xmldoc.save(Server.MapPath("allcity.xml"))
Response.Write("创建成功！")
</script>

5.遍历XML文档
<%@ Language=VBScript %>
<% Option Explicit %>
<table border="1"><tr><th>Name</th><th>Number of Songs</th></tr>
<%
Dim objParser,objRoot,objNode,i
Set objParser=Server.CreateObject("MSXML.DOMDocument")
objParser.Load(Server.MapPath(%%1)) //"albums.xml"
Set objRoot=objParser.documentElement
For i=0 To (objRoot.childNodes.length-1)
If objRoot.childNodes.Item(i).baseName="album" Then
Set objNode=objRoot.childNodes.Item(i)
Response.Write "<tr><td>"
Response.Write objNode.getAttribute("name") & "</td><td align='center'>"
Response.Write objNode.childNodes.length
End if
Next
%>
</td></tr>
</table>

6.搜索XML元素
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
Dim objDocument,objRoot,objNode,objNodeList
Set objDocument=Server.CreateObject("MSXML.DOMDocument")
objDocument.Load(Server.MapPath(%%1)) //"albums.xml"
Set objRoot=objDocument.docmentElement
Set objNodeList=objRoot.SelectNodes("//ablum[@artist='" & Request.Form("artist") & "']")
If objNodeList.length=0 Then
Response.Write "No matches"
Else
Response.Write "<table border='1'><tr><th>Album</th><th>Year</th></tr>"
For each objNode in objNodeList
Response.Write "<tr><td>" & objNode.getAttribute("name")
Response.Write "</td><td>" & objNode.getAttribute("releaseDate") & "</td></tr>"
Next
Response.Write "</table>"
End If
End If
//%>

7.下载文件
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
call downloadFile(replace(Request("file"),"",""))

Function downloadFile(strFile)
' make sure you are on the latest MDAC version for this to work
' get full path of specified file
strFilename = server.MapPath(strFile)

' clear the buffer
Response.Buffer = True
Response.Clear

' create stream
Set s = Server.CreateObject("ADODB.Stream")
s.Open

' Set as binary
s.Type = 1

' load in the file
on error resume next

' check the file exists
Set fso = Server.CreateObject("Scripting.FileSystemObject")
if not fso.FileExists(strFilename) then
Response.Write("<h1>Error:</h1>" & strFilename & " does not exist<p>")
Response.End
end if

' get length of file
Set f = fso.GetFile(strFilename)
intFilelength = f.size

s.LoadFromFile(strFilename)
if err then
Response.Write("<h1>Error: </h1>" & err.Description & "<p>")
Response.End
end if

' send the headers to the users browser
Response.AddHeader "Content-Disposition", "attachment; filename=" & f.name
Response.AddHeader "Content-Length", intFilelength
Response.CharSet = "UTF-8"
Response.ContentType = "application/octet-stream"

' output the file to the browser
Response.BinaryWrite s.Read
Response.Flush

' tidy up
s.Close
Set s = Nothing
End Function
//%>

8.调用存储过程查询
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
dim db,conn,myconn
db="/database/product.mdb"
Set conn = Server.CreateObject("ADODB.Connection")
myconn="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(""&db&"")
conn.Open MyConn
dim rs
dim sql
dim keyword
dim choose
keyword=request("keyword") '接收页面传送的值
choose=request("choose")
set rs=server.createobject("adodb.recordset")
sql="exec tse" '用exec执行tse存储过程，把keyword，choose给存储过程传递参数
rs.open sql,conn,1,1
if rs.eof and rs.bof then
response.write("没有任何记录！")
response.end
end if
response.write"搜索到的记录如下:<br><br>"
do until rs.eof
response.write""&rs("id")&":"&rs("title")&"" '打印出文章的ID和标题
response.write"<br><br>"
rs.movenext
loop
'打扫战场
rs.close
conn.close
set rs=nothing
set conn = nothing
//%>

9.参数存储过程查询
'存储过程：
'在SQL中建立dbo.tse存储过程
CREATE PROCEDURE [dbo].[tse]
@keyword varchar(20)=null, '定义查询的关键字
@choose int=null '定义查询的类型（1为查询列title,其他为content）
as
if @choose=1
select * from web where title like @keyword + '%'
else
select * from web where content like @keyword + '%'
return
GO
'list.asp页
<%@ Language=VBScript %>
<% Option Explicit %>

rs.open sql,conn,1,1
if rs.eof and rs.bof then
response.write("没有任何记录！")
response.end
end if
response.write"搜索到的记录如下:<br><br>"
do until rs.eof

Answer 2

ACCESS执行的是ANSI SQL标准,你可以查询相关的SQL语法可知道.

SQL语法有二类
数据库操作语法:
create table
create view
alter table修改
等等
数据库安全语法:
包含授权与回收权限等
数据操作语法:
select
update
insert
等
事务处理语法:
ACCESS不支持,所以不需要再看了!

所以你应该去学的是SQL,记着如果是ACCESS时,使用ANSI SQL,Trans-SQL是不支持ACCESS的,虽然两者的差别很小!大多数时间语句是相同的,但毕竞不是一个语法标准.

Answer 3

好象没这样的东西吧,不管什么代码操作accsee数据库主要就四种命令:
SELECT 查询
UPDATE 更新
DELETE 删除
INSERT 插入
这四种命令都属于SQL语言,学一下SQL语法就行了

Answer 4

买一两本入门的书，学习吧
