一个简单的SQL语句执行器

2008-02-23 05:06:44来源：互联网阅读 ()

大至分为三个文件：ljmdb.asp(连接库文件)、entice.asp(sql语句执行主界面)、entice2.asp(select记录集)

====================================ljmdb.asp
<%
set conndb=server.createobject("ADODB.CONNECTION")
constr="provider=microsoft.jet.oledb.4.0;data

source="&server.mappath("/aspsky.myip.org/entice.mdb")
conndb.open constr
%>
'这是连接access的，把数据库的地址改成你自己的地址就行了

====================================entice.asp
<%
if left(trim(request("sqllanguage")),6)="select" then
%>
<script language=javascript>
window.open("entice2.asp?sql=<%=request("sqllanguage")%>","","height=450,width=600,resizable=yes,

scrollbars=yes,status=no,toolbar=no,menubar=no,location=no")
</script>
<%
end if
%>

%>
<HTML>
<Title>SOL语句执行示例 </Title>
<style type="text/css">

</style>
<Body Bgcolor=#009999>
<%
sqllanguage=Request("sqllanguage")
%>
<Form Name="FormPst" Method="Post" Action="entice.asp">
<div align="center"><FieldSet> <Legend>请输入SQL语句</Legend> 指令：
<Input type="text" name="sqllanguage" Size=60>
<Input type="Submit" Value="送出">

</form>
<Hr>
SQL 语句执行情况：

<%
if sqllanguage<>Empty then
On Error Resume Next
conndb.Execute(sqllanguage)
if err.number="0" then
message1="执行成功"
response.write message1
else
message1=err.description
response.write message1
err.clear
end if
end if
%>

<%
set rstable=conndb.openSchema(20)
rstable.movefirst
%>
<table width="95%" border="0" cellspacing="1" cellpadding="3" align="center" bgcolor="#000000">
<%
do while not rstable.eof
if rstable("table_type")="TABLE" then
%>
<tr bgcolor="#006400">
<td width="18%" nowrap><font color="#FFFFFF">数据库中的表名</font></td>
<td width="82%" nowrap> <font color="#FFFFFF">
<%

response.write rstable("table_name")
%>
</font></td>
</tr>
<tr bgcolor="#CCCCCC">
<td width="18%" nowrap>该表中的所有字段</td>
<td width="82%" nowrap>
<%
set rstobj=server.createobject("adodb.recordset")
rstsql="select * from "&rstable("table_name")
rstobj.open rstsql,conndb,1
for i=0 to rstobj.fields.count-1
response.write rstobj(i).name&"|"
next
rstobj.close
set rstobj=nothing
%>
</td>
</tr>
<%
end if
rstable.movenext
loop
rstable.close
set rstable=nothing
%>
</table>
</Body>
</HTML>
<%
conndb.close
set conndb=nothing
