如何在VBScript中逐行读取CSV文件 [英] How to read CSV files line by line in VBScript

问题描述

我使用的是一个ASP页面，我必须读取一个CSV文件，并将其插入到DB表Employee。我创建一个TestReader的对象。

I am using an ASP page where I have to read a CSV file and insert it into DB table "Employee". I am creating an object of TestReader. How can I write a loop to execute up to the number of rows/records of the CSV file which is being read?

推荐答案

如何编写一个循环以执行多达正在读取的CSV文件的行数/记录数？不要尝试自己解析文件，你只会给自己头痛。有更多的东西比拆分换行和逗号。

Do not try to parse the file yourself, you'll just give yourself a headache. There's quite a bit more to it than splitting on newline and commas.

您可以使用OLEDB在记录集中打开文件，并像读取数据库表一样读取它。像这样：

You can use OLEDB to open up the file in a recordset and read it just as you would a db table. Something like this:

Dim strConn, conn, rs

strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
Server.MapPath("path to folder") & ";Extended Properties='text;HDR=Yes;FMT-Delimited';"

Set conn = Server.CreateObject("ADODB.Connection")
conn.Open strConn

Set rs = Server.CreateObject("ADODB.recordset")
rs.open "SELECT * FROM myfile.csv", conn

while not rs.eof
    ...
    rs.movenext
wend

我的vbscript很生锈，请验证语法。

My vbscript is rusty, so verify the syntax.

编辑： harpo的评论提出了关于字段定义的好点。定义schema.ini文件允许您定义期望字段的数量和数据类型。请参阅：您可以通过定义schema.ini文件来处理此问题。请参阅： http://msdn.microsoft.com/en-us/library/ms709353 .aspx

edit: harpo's comment brings up a good point about field definitions. Defining a schema.ini file allows you to define the number and datatypes of the expected fields. See: You can handle this by defining a schema.ini file. see: http://msdn.microsoft.com/en-us/library/ms709353.aspx
