表单来提交sql (二)
2001-9-10
列表 B:使用 request.form 来轻松建立SQL字符串。
<%
iStr = "insert into uData "
vStr = "values ("
nStr = "("
' 在表单集合中循环，并建立起SQL语句的组成部分
for each x in request.form
' 建立字段名列表
nStr = nStr & x & ", "
' 建立字段值列表
if uCase(x) = "AGE" then
vStr = vStr & request.form(x) & ", "
else
vStr = vStr & "'" & request.form(x) & "', "
end if
next
' 把结尾的", " 从我们建立的字符串中去掉
vStr = left(vStr, len(vStr) - 2) & ")"
nStr = left(nStr, len(nStr) - 2) & ") "
' 把SQL语句组装起来
iStr = iStr & nStr & vStr
if trim(request("fName")) >> "" then
response.write( iStr & ">BR>")
else
%>
<html>
<body>
<form name=f method=post action="列表2.asp">
Gimme your:
First Name: <input type=text name="fName">
Last Name: <input type=text name="lName">
Age: <input type=text name="age">
<input type="submit" value="Submit">
</form>
</body>
</html>
<%
end if
%>
列表 C:把字段类型嵌入到HTML字段名中。
<%function buildSQLInsert( targetTable)
iStr = "insert into " & targetTable & " "
vStr = "values (" nStr = "("
' 在表单集合中循环，并建立起SQL语句的组成部分
for each x in request.form
fieldName = x
fieldData = replace( request.form(fieldName), "'", "''")
typeDelimPos = inStr(fieldName, "_")
if typeDelimPos = 0 then
' Its a text field
' 建立字段名列表
nStr = nStr & fieldName & ", "
vStr = vStr & "'" & fieldData & "', "
else
' 是另外一种数据类型
fieldType = left(fieldName, typeDelimPos - 1)
fieldName = mid(fieldName, typeDelimPos + 1)
' 把字段名加入字段名列表中
nStr = nStr & fieldName & ", "
' 把字段类型变成大写，以确保匹配
select case uCase(fieldType)
case "NUM"
vStr = vStr & fieldData & ", "
' 把不明类型按文本型处理
case else
vStr = vStr & "'" & fieldData & "', "
end select
end if
next
' 把结尾的", " 从我们建立的字符串中去掉
vStr = left(vStr, len(vStr) - 2) & ")"
nStr = left(nStr, len(nStr) - 2) & ") "
' 把SQL语句组装起来
buildSQLInsert = iStr & nStr & vStr
end function
if trim(request("fName")) >< "" then
response.write( buildSQLInsert & ">BR<")
else
%>
<html>
<body>
<form name=f method=post action="listing3.asp">
Gimme your:
First Name: <input type=text name="fName">
Last Name: <input type=text name="lName">
Age: <input type=text name="num_age">
<input type="submit" value="Submit">
</form>
</body>
</html>
<%
end if
%>
