PowerShell Multiple SQL Query Function Outputs as CSV

Question

I'm having trouble running PowerShell to run multiple SQL queries and export the results to CSV.

I try to accomplish this using Function, but the problem occurs in the block Processwhen I expect two requests to be launched and two CSV files will be output.

I tried to create one function to run a query and a second function to create CSV files, but did not even execute SQL queries. I do this without installing SQL where this powershell script runs. -Thank!

Function Run-Query {
 param([string[]]$queries,[string[]]$sheetnames)
Begin{
 $SQLServer = 'ServerName'
 $Database = 'DataBase'
 $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
 $SqlConnection.ConnectionString = "Server = $SQLServer; Database = $Database; Integrated Security = True"
}#End Begin
Process{
 $SqlCmd = New-Object System.Data.SqlClient.SqlCommand
 $SqlCmd.CommandText = $queries
 $SqlCmd.Connection = $SqlConnection
 $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
 $SqlAdapter.SelectCommand = $SqlCmd
 $DataSet = New-Object System.Data.DataSet
 $SqlAdapter.Fill($DataSet)
 $DataSet.Tables[0] | Export-Csv -NoTypeInformation -Path "C:\Scripts\$sheetnames.csv"
}#End Process
End{
 $SqlConnection.Close()
}
}#End function run-query.
$queries = @()
 $queries += @'
Select * from something
'@
 $queries += @'
Select * from something2
'@
$sheetnames = @()
$sheetnames += 'Cert'
$sheetnames += 'Prod'
Run-Query -queries $queries

Function Run-Query
{
    param([string[]]$queries,[string[]]$sheetnames)
    Begin
    {
        $SQLServer = 'ServerName'
        $Database = 'DataBase'
        $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
        $SqlConnection.ConnectionString = "Server = $SQLServer; Database = $Database; Integrated Security = True"
    }#End Begin
    Process
    {
        # Loop through each query
        For($i = 0; $i -lt $queries.count; $i++)
        {
            $SqlCmd = New-Object System.Data.SqlClient.SqlCommand

            # Use the current index ($i) to get the query
            $SqlCmd.CommandText = $queries[$i]

            $SqlCmd.Connection = $SqlConnection
            $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
            $SqlAdapter.SelectCommand = $SqlCmd
            $DataSet = New-Object System.Data.DataSet
            $SqlAdapter.Fill($DataSet)

            # Use the current index ($i) to get the sheetname for the CSV
            $DataSet.Tables[0] | Export-Csv -NoTypeInformation -Path "C:\Scripts\$($sheetnames[$i]).csv"
        }
    }#End Process
    End
    {
        $SqlConnection.Close()
    }
}#End function run-query.

$queries = @()

$queries += @'
Select * from something
'@
$queries += @'
Select * from something2
'@

$sheetnames = @()
$sheetnames += 'Cert'
$sheetnames += 'Prod'

Run-Query -queries $queries -sheetnames $sheetnames
