通过 ADODB.Connection 读取 Excel(xls 和 xlsx)中的第二行作为列标题时,如何使用它???
- Excel来自客户
- Excel 在上传到 ASP 页面之前不能更改
- 第一行是 Excel 报告的 TITLE(我想忽略)
当前解决方案(代码在最后):
- 客户上传 Excel
- 将备份副本创建为“原始”
- 打开并读取 Excel 的前 2 行
- 用第 2 行的值覆盖第 1 行
- 前 2 行现在相同
- 关闭并重新打开 Excel
- 选择除等于列名名称的值之外的所有内容 - 例如从 [Sheet1$] 中选择 column1、column2、column3... where ucase(column1) <> 'COLUMN1'
- 阅读 Excel 并打印 HTML
我想不通的可能想法:
- 将“命名范围”分配给第二行
- 删除第一行(用 ADO 和 Excel 看起来不可能)
- 在 VBA 中使用 HeaderRowRange.Address 将标题行更改为第 2 行
- 不要在当前解决方案中创建副本,而是读取第 2 行及以下的所有内容,然后保存到新的 Excel
当前解决方案的代码:
' ---------------------------------------------------------------------
' 1. Client uploads Excel
' ---------------------------------------------------------------------
xlsfolder = "D:\website\excels\"
filename = request("filename_from_asp_upload_form")
xlsfile = xlsfolder & filename
' ---------------------------------------------------------------------
' 2. Create backup copy as "original"
' ---------------------------------------------------------------------
dim fscopy
set fscopy=Server.CreateObject("Scripting.FileSystemObject")
exceltypelower = fscopy.GetExtensionName(xlsfile)
replace_text = "_BACKUP." & exceltypelower
xlsfile_copy = replace(xlsfile, ("." & exceltypelower), replace_text)
fscopy.CopyFile xlsfile,xlsfile_copy
set fscopy=nothing
' ---------------------------------------------------------------------
' EXTRA STEP - SELECT EXCEL DRIVER
' ---------------------------------------------------------------------
if exceltype = "XLS" then
exceldriver = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & xlsfile & ";Extended Properties=""Excel 8.0;"""
elseif exceltype = "XLSX" then
exceldriver = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & xlsfile & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"""
exceldriver2 = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & xlsfile & ";Extended Properties=""Excel 8.0;HDR=No;"""
'*** Second driver allows first row to be read as data and not header allowing Excel cells to be overwritten
else
'**** default to 97-2003 format. ELSE just in case
exceldriver = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & xlsfile & ";Extended Properties=""Excel 8.0;"""
end if
' ---------------------------------------------------------------------
' 3. Open and Read first 2 rows of Excel
' 4. Overwrite row 1 with values from row 2
' ---------------------------------------------------------------------
' NOTE: There is another step at UPLOAD that the user flags what kind of Excel Report it is.
' Since there are just a few now, I have the skip_title variable hard-coded
' IF SKIP_TITLE = "Y"... that means the column headers are on row 2
' IF SKIP_TITLE = "N"... that means the column headers are on row 1 and this is unnecessary
' ---------------------------------------------------------------------
if skip_title = "Y" then
excel_query2 = "Select * from [Sheet1$] "
Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adUseClient = 3
Set objConn = CreateObject("ADODB.Connection")
Set objRecordset = CreateObject("ADODB.Recordset")
objConn.Open (exceldriver2)
objRecordset.CursorLocation = adUseClient
objRecordset.Open excel_query2 , objConn, adOpenStatic, adLockOptimistic
counter = 1
headcount = 0
colcount = objRecordSet.Fields.Count ' How many columns there are to traverse
p = objRecordSet.GetRows(colcount,0) ' Write excel_query2 results for number of columns above
objRecordSet.MoveFirst
do until objRecordSet.EOF or counter = 0
for each x in objRecordSet.Fields
objRecordSet.Fields(headcount).Value = p(headcount, 1) 'overwrite row 1 with row 2
headcount = headcount + 1
next
counter = counter - 1
objRecordSet.MoveNext
loop
objRecordSet.Update
objRecordset.Close
objConn.Close
end if
' ---------------------------------------------------------------------
' 5. The first 2 rows are now identical
' 6. Close and Re-Open Excel
' ---------------------------------------------------------------------
set objConnection = Server.CreateObject("ADODB.Connection")
objConnection.Open (exceldriver)
' ---------------------------------------------------------------------
' 7. Select everything except values that equal name of column names
' -e.g. Select column1, column2, column3... from [Sheet1$] where ucase(column1) <> 'COLUMN1'
' ---------------------------------------------------------------------
excel_query = "Select column1, column2, column3... from [Sheet1$] where ucase(column1) <> 'COLUMN1' " 'example
set objRS = objConnection.execute(excel_query)
' ---------------------------------------------------------------------
' 8. Read Excel and Print HTML
' ---------------------------------------------------------------------
response.write "<table><thead><tr>"
for each x in objRS.Fields
response.write("<th>" & ucase(x.name) & "</th>")
next
response.write "</tr></thead>"
