我有一个powershell脚本,它从SQL数据库中提取数据并填充数据表,然后将内容写入csv文件。脚本如下:
$dataSource = "DESKTOP-9CRH1HF\SQLEXPRESS"
$user = "sa"
$pwd = "Not4U2c@Al!"
$database = "Xperdyte"
$connectionString = "Server=$dataSource;uid=$user; pwd=$pwd;Database=$database;Integrated Security=False;"
$query = "SELECT * from dbo.v_SpecProd_Export"
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$command = $connection.CreateCommand()
$command.CommandText = $query
$result = $command.ExecuteReader()
$table = new-object “System.Data.DataTable”
$table.Load($result)
$table | Export-Csv -path c:\temp\temp.csv -NoTypeInformation -Delimiter ";"
Get-Content c:\temp\temp.csv | select -Skip 1 | % {$_ -replace '"', ""} | Set-Content c:\temp\Xperdyte.csv
move-item "c:\temp\Xperdyte.csv" ("c:\1_PRODUCTION\ARMOR\Bom\DocProd_Africa_{0:yyyyMMdd_HHmmss}.csv" -f (get-date))
$connection.Close()
CSV文件中的输出如下:
1008891;20.000000;Roll;20;;TSB876ZA;06;;L15832ZA;Clear Leader Roll 300mm x 400m 22mic;4.060000;M ;1;;S80795XL;0

第4列包含有效数据,正确的数据存储在共享驱动器上的excel文件中。将正确的数据导入SQL不是一种选择,因为我试图在不影响SQL的情况下集成两个系统。每个Excel文件都根据产品代码命名,该代码也是SQL数据库中的值(csv文件中的第6列)。每个Excel文件的内容如下所示,每个文件包含不同的数据,具体取决于产品代码:
1005 TMA208 CORE.CARDBOARD 25.4X33X1000MM (Black Stripes) 50 m CORE_WI 10

我想要实现的是读取System.Data.Datatable(第6列)以查找产品代码并将其存储为变量,然后搜索同名的Excel文件,读取excel文件的内容并将存储数据表中的第9列与excel文件中的第2列匹配。一旦我在excel文件中返回第7列并使用此值更新数据表中的第4列。在最终写入CSV文件之前,我需要对数据表中的每一行执行此操作。
我发现下面的代码我认为可以根据我的需要进行操作并将其集成到我的ps脚本中,但我不确定这是否正确,或者是否有更快的方法来执行此操作? / p>
#Declare the file path and sheet name
$file = "C:\Users\kfeb\Documents\Textfile\ExcelFile.xlsx"
$sheetName = "Sheet1"
#Create an instance of Excel.Application and Open Excel file
$objExcel = New-Object -ComObject Excel.Application
$workbook = $objExcel.Workbooks.Open($file)
$sheet = $workbook.Worksheets.Item($sheetName)
$objExcel.Visible=$false
#Count max row
$rowMax = ($sheet.UsedRange.Rows).count
#Declare the starting positions
$rowName,$colName = 1,1
$rowAge,$colAge = 1,2
$rowCity,$colCity = 1,3
#loop to get values and store it
for ($i=1; $i -le $rowMax-1; $i++)
{
$name = $sheet.Cells.Item($rowName+$i,$colName).text
$age = $sheet.Cells.Item($rowAge+$i,$colAge).text
$city = $sheet.Cells.Item($rowCity+$i,$colCity).text
Write-Host ("My Name is: "+$name)
Write-Host ("My Age is: "+$age)
Write-Host ("I live in: "+$city)
}
#close excel file
$objExcel.quit()
任何人都可以理解这个问题,如果有的话可以提供一些方向吗?
谢谢, 史蒂芬

因此,您希望从CSV中获取第6列(产品代码),将其与第9列(也是产品代码)匹配,并从Excel文件中查找第7列并将其保存到CSV中的第4列。
首先,从Excel工作表中获取所有数据。我假设您的Excel文件中没有标题行,您需要正确指定工作表名称和文件名。
#Declare the file path and sheet name
$file = "C:\Users\kfeb\Documents\Textfile\ExcelFile.xlsx"
$sheetName = "Sheet1"
#Create an instance of Excel.Application and Open Excel file
$objExcel = New-Object -ComObject Excel.Application
$workbook = $objExcel.Workbooks.Open($file)
$sheet = $workbook.Worksheets.Item($sheetName)
$objExcel.Visible=$false
#Count max row
$rowMax = ($sheet.UsedRange.Rows).count
$colProductCodeExcel = 9
$colOtherColumnExcel = 7
$SheetData = @{}
for ($row = 1; $row -le $rowMax; ++$row) {
$SheetProductCode = $sheet.Cells.Item($i,$colProductCodeExcel).text
$SheetOtherColumn = $sheet.Cells.Item($i,$colOtherColumnExcel).text
$SheetData[$SheetProductCode] = $SheetOtherColumn
}
$objExcel.Quit()
现在$SheetData
是一个查找表。如果您有重复的产品代码,$SheetData
将在工作表中包含最后一个其他列值。
现在,从SQL中获取数据:
$dataSource = "DESKTOP-9CRH1HF\SQLEXPRESS"
$user = "sa"
$pwd = "Not4U2c@Al!"
$database = "Xperdyte"
$connectionString = "Server=$dataSource;uid=$user; pwd=$pwd;Database=$database;Integrated Security=False;"
$query = "SELECT * from dbo.v_SpecProd_Export"
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$command = $connection.CreateCommand()
$command.CommandText = $query
$result = $command.ExecuteReader()
$table = new-object “System.Data.DataTable”
$table.Load($result)
$connection.Dispose()
$colProductCodeSql = 6
$colOtherColumnSql = 4
$table |
ForEach-Object {
$_[$colOtherColumnSql] = $SheetData[$_[$colProductCodeSql]]
} |
ConvertTo-Csv -NoTypeInformation -Delimiter ';' |
Select-Object -Skip 1 |
ForEach-Object { $_ -replace '"', "" } |
Set-Content c:\temp\Xperdyte.csv
如果$colOtherColumnSql
的数据类型与$SheetData[$colProductCodeSql]
不匹配,则可能会出现错误或输入转换问题。谨防领先或尾随空格。
我没有测试过任何上述代码。如果有错误,我不会感到惊讶。

Bacon Bits完全走上正轨,只是遗漏了多个文件。此外,如果您使用现代版本的PowerShell将表导入PowerShell要容易得多。所以,我会创建一个HashTable,并根据需要将Excel数据加载到嵌套的HashTable中。
$RawCSV = GC c:\temp\Xperdyte.csv
$Headers = 1..$RawCSV[0].Split(';').Count|%{"Column$_"}
$CSV = $RawCSV | ConvertFrom-Csv -Delimiter ';' -Header $Headers
$Lookup = @{}
$XL = New-Object -ComObject Excel.Application
ForEach($File in ($CSV.Column6|Select -Unique)){
#Create record in main HT for this Excel file with an empty HT for the value
$Lookup.Add($File,@{})
#Open the workbook and import the data
$WB = $XL.Workbooks.Open("C:\Users\kfeb\Documents\Textfile\$File.xlsx")
$WB.ActiveSheet.UsedRange.Rows | ForEach{$Lookup[$File].($_.Cells.Item(2).Value2) = $_.Cells.Item(7).Value2}
#Close the workbook
$wb.Close($false) | Out-Null
}
#Close Excel
$XL.Quit()|Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($XL) | Out-Null
Remove-Variable XL
$Output = ForEach($Item in $CSV){
#If the item code can be found in the lookup table update Column4
If($Item.Column9 -in $Lookup[($Item.Column6)].Keys){$Item.Column4 = $Lookup[($Item.Column6)][($Item.Column9)]}
($Headers|%{$Item.$_}) -join ';'
}
$Output | Set-Content ("c:\1_PRODUCTION\ARMOR\Bom\DocProd_Africa_{0:yyyyMMdd_HHmmss}.csv" -f (get-date))
