数据库设计的小网站，表单多而操作简单，一般就只有插入删除修改等操作。每次都要重复写插入修改的SQL，
是不是觉得很麻烦呢，我是这么觉得，所以，自己写了一个自动产生插入，修改的SQL，就方便多了，一下是ASP代码，
对ACCESS，SQL Server都适用。如果对你有帮助，可以拿去用用，还可以改进。

Dim tableName,strSQL,rsFields,fieldsCount,totalCount
Dim insertSQL,iFields,iDataFields,updateSQL,deleteSQL
Dim keyFieldName,funQuote
Dim conn
dim dbPath
'SQL SERVER 连接字符串
'conn.Open("Driver={sql server};server=sundy;database=test;uid=sa;pwd=;")
Set conn = Server.CreateObject("ADODB.Connection")
'下面以Access数据库为例
dbconn = "driver={Microsoft Access Driver (*.mdb)};dbq=" & SERVER.MapPath("data/db.mdb")
conn.open dbconn
'表的主键字段名
keyFieldName = request.Form("keyfield")
'用于过滤提交表单中的“'“的函数名
funQuote = request.Form("funQuote")
'表名
tableName = request("tableName")
If request.Form("subTable")<> "" Then
strSQL = "Select Top 1 * From " & tableName
set rsFields = Server.CreateObject("Adodb.recordset")
rsFields.open strSQL,conn,1,1
fieldsCount = rsFields.Fields.count
insertSQL = """INSERT INTO " & tableName & "("" & _" & vbCrlf
updateSQL = """UPDATE " & tableName & " SET "" & _" & vbCrlf
For i = 0 TO fieldsCount - 1
If INSTR(",3,202,203,","," & rsFields.fields(i).type & ",") > 0 AND Ucase(rsFields.fields(i).name) <> Ucase(keyFieldName) Then
iFields = iFields & """" & rsFields.Fields(i).name
Select case rsFields.fields(i).type
case 3 'INT
