Split values using Powershell - sql-server

Question

I have a file with multiple expressions like "$REGX('CareMedic.2_0','CustomerInformation','Customer Information')". The file can be a xml file, text file or any other type. If the file contains 9 of those expressions, I'm trying to pull all nine and send the values to a database.
I've tried my code as below:
$input_path = ‘C:\Users\Administrator\Desktop\test2.xml’
$SQLServer = "WIN-17V7QT0IJVK"
$SQLDBName = "Test"
$uid ="WIN-17V7QT0IJVK\Administrator"
$pwd = "letmebackinplease"
$SqlQuery = "SELECT * from product_schema;"
$ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection $ConnectionString
$SqlConnection.open()
if($SqlConnection.state -eq "Open"){
Write-Host "Test connection successful"
}
$regex = '()\(.*?\)'
$output = select-string -Path $input_path -Pattern $regex -AllMatches | % { $.Matches } | % { $.Value } |
ForEach-Object {
($_ -split "\(|\)")[1]
}
foreach ($line in $output){
$line = $line -replace "\(",""
$line = $line -replace "\)",""
$line = $line -replace "\'",""
$col1,$col2,$col3 = $line -split ","
[PSCustomObject]#{
col1 = $col1
col2 = $col2
col3 = $col3
} | select col1,col2,col3
$insert_query = "INSERT INTO [$SQLDBName].[dbo].[product_schema]
([version]
,[field]
,[value])
VALUES
($col1, $col2, $col3);"
$execute_query = New-Object System.Data.SqlClient.SqlCommand
$execute_query.connection = $SQLConnection
$execute_query.commandtext = $insert_query
$execute_query.ExecuteNonQuery()
}
$SqlConnection.close()
If the file has two of the below:
('Medic.2_0','AgeInformation','Age Information')
('Medic.2_0','TransactionID','Transaction ID')
My actual output should be:
'Medic.2_0' stored in Version Column
'AgeInformation' stored in the Field Column
'Age Information' stored in the value column
'Medic.2_0' stored in Version Column
'TransactionID' stored in the Field Column
'Transaction ID' stored in the value column
I have to take each of the values and store it in a column in a temp table setup on MySQL server like below:
**Version** **Field** **Value**
Medic.2_0 AgeInformation Age Information
Medic.2_0 TransactionID Transaction ID
Error Encountered:
Exception calling "ExecuteNonQuery" with "0" argument(s): "Incorrect syntax near '.2'."
At C:\Users\Administrator\Desktop\test.ps1:47 char:10
+ $execute_query.ExecuteNonQuery()
+ ~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : SqlException
Can someone please recommend how shall I change my code to solve this?

Answer 1

In answer to your original question before editing: Assuming your output looks like this and is saved in a variable named $output
('Medic.2_0','AgeInformation','Age Information')
('Medic.2_0','TransactionID','Transaction ID')
Try this:
foreach ($line in $output){
$line = $line -replace "\(",""
$line = $line -replace "\)",""
$line = $line -replace "\'",""
$col1,$col2,$col3 = $line -split ","
[PSCustomObject]#{
col1 = $col1
col2 = $col2
col3 = $col3
} | select col1,col2,col3 | export-csv d:\test.csv -append -NoTypeInformation
}
We are looping through the $output line by line removing the brackets and the single quotes, splitting the remaining text on the comma, then assigning each of the three entries into the relevant variables. Once they are in variables we can then easily create a PSObject and use it to select our requirements for our export-csv

Answer 2

Try to add this code:
$info=#() #for store your values
foreach($item in $output){
$z=$item.split(',') #for split to 3 strings
$info+=[PSCustomObject]#{ #create custom object which have named columns and store our values
Version = $z[0]
Field = $z[1]
Value = $z[2]
}
}
Write-Output $info #variable that store all columns
Then you must run foreach loop to each object in $info .
you can run it like this:
foreach($data in $info){
$data.Version #to access Version field
$data.Field #to access Field field
$data.Value #to access Value field
.......your SQL query......
}
