【问题描述】:
我正在尝试从经典 asp 中导出 csv。 oracle DB 正在获取数据。该查询返回超过 2500 行。这是我尝试使用的代码:
<%
sub Write_CSV_From_Recordset(RS)
if RS.EOF then
'
' There is no data to be written
'
exit sub
end if
dim RX
set RX = new RegExp
RX.Pattern = "\r|\n|,|"""
dim i
dim Field
dim Separator
'
' Writing the header row (header row contains field names)
'
Separator = ""
for i = 0 to RS.Fields.Count - 1
Field = RS.Fields(i).Name
if RX.Test(Field) then
'
' According to recommendations:
' - Fields that contain CR/LF, Comma or Double-quote should be enclosed in double-quotes
' - Double-quote itself must be escaped by preceeding with another double-quote
'
Field = """" & Replace(Field, """", """""") & """"
end if
Response.Write Separator & Field
Separator = ","
next
Response.Write vbNewLine
'
' Writing the data rows
'
do until RS.EOF
Separator = ""
for i = 0 to RS.Fields.Count - 1
'
' Note the concatenation with empty string below
' This assures that NULL values are converted to empty string
'
Field = RS.Fields(i).Value & ""
if RX.Test(Field) then
Field = """" & Replace(Field, """", """""") & """"
end if
Response.Write Separator & Field
Separator = ","
next
Response.Write vbNewLine
RS.MoveNext
loop
end sub
Response.Buffer = True
Response.ContentType = "text/csv"
Response.AddHeader "Content-Disposition", "attachment; filename=Export.csv"
theSQL = Session("Query")
Set RS = Connection.Execute(theSQL)
Write_CSV_From_Recordset RS
%>
<html>
<head>
<title>Excel/CSV Export</title>
</head>
<body>
</body>
</html>
但我得到的只是站点无法访问的错误。我什至尝试在页面上显示数据并通过更改内容类型和文件扩展名导出到 excel。这适用于更少的行数。但是当查询获取的记录数较多时,只会报站点不可达错误。
谁能帮我解决这个问题。
