Question

I have powershell version 2.0.0.1082 on my server. I want to import data from a text file to SQL server, and add two new fields (character and current datetime) to the input to SQL 2008 database. I have been using bulk import or SSIS to do it but I want to use powershell for the ease of maintaining the process. The file has column name at top and each field is seperated by “|”.
Code so far:

clear

 import-csv "Disk.txt" -Delimiter "|" | 
 foreach { add-member -in $_ -membertype noteproperty DateRecorded $((Get-Date).ToString("yyyy-MM-dd")) 
 add-member -in $_ -membertype noteproperty SystemName 'System Name'
 add-member -in $_ -membertype noteproperty Drive 'Drive Letter'
 add-member -in $_ -membertype noteproperty TotalSizeGB 'Total Size'
 add-member -in $_ -membertype noteproperty UsedGB Used
 add-member -in $_ -membertype noteproperty FreeGB Free
 add-member -in $_ -membertype noteproperty PercentFree '% Free'}|
select DateRecorded,SystemName,Drive,TotalSizeGB,UsedGB,FreeGB,PercentFree |Format-Table

Any ideas please?

Thanks!

You’ll either need to add the -PassThru switch to the Add-Member cmdlet to forward the objects on in the pipeline or put $_ all by itself at the end of the ForEach block.

Here is an example using -PassThru:

Import-Csv "Disk.txt" -Delimiter "|" | ForEach {
    Add-Member -InputObject $_ -MemberType NoteProperty -name "DateRecorded" -value $((Get-Date).ToString("yyyy-MM-dd"))
    Add-Member -InputObject $_ -MemberType NoteProperty -name "SystemName" -value 'System Name' -PassThru
} | Select DateRecorded,SystemName,Drive,TotalSizeGB,UsedGB,FreeGB,PercentFree | Format-Table

Another example without -PassThru:

Import-Csv "Disk.txt" -Delimiter "|" | ForEach {
    Add-Member -InputObject $_ -MemberType NoteProperty -name "DateRecorded" -value $((Get-Date).ToString("yyyy-MM-dd"))
    Add-Member -InputObject $_ -MemberType NoteProperty -name "SystemName" -value 'System Name'
    $_
} | Select DateRecorded,SystemName,Drive,TotalSizeGB,UsedGB,FreeGB,PercentFree | Format-Table

Once you’ve prepared your CSV data for input into the database you can use the Invoke-SqlCmd cmdlet that comes with SQL Server 2008 to perform Inserts. There is a wealth of information on MSDN here to show you how.
