Iterating/Executing TSQL-Scripts in Subfolders throws an error

Question

Hi Forum,
the idea: I have several subfolders containing tsql-scripts. I want to change into a folder and execute every script - sorted by name (important because of dependencies).
I have an array with Subfolder names, I build on fly an array wiht script names inside of every subfolder, I'm reading the content of a tsql-file (sentence by sentence), I'm paying attention for a "go" statement and then execute the command.
When the first script doesn't end with a "go" statement, I'll get an error executing the first line of the second script.
I don't know where to set my command-variable to $null or to blank (" ").
For example the first script is:
DECLARE @CMD varchar(500)
SET @CMD = 'EXEC sp_configure ''show advanced option'', ''1'';
reconfigure with override
EXEC sp_configure ''xp_cmdshell'',''1''
reconfigure with override'
print @CMD
EXEC (@CMD)
..and the second begins with:
sp_configure 'allow updates','1'
go
reconfigure with override
GO
then I get an error:
DECLARE @CMD varchar(500)
SET @CMD = 'EXEC sp_configure ''show advanced option'', ''1'';
       reconfigure with override
            EXEC sp_configure ''xp_cmdshell'',''1''
            reconfigure with override'
print @CMD
EXEC (@CMD)
sp_configure 'allow updates','1'
Exception calling "ExecuteScalar" with "0" argument(s): "Incorrect syntax near 'allow updates'."

+                         $SQLCommand.ExecuteScalar <<<< ()
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException
My PSScript looks like that:
param(
#$ServerName
[parameter(Mandatory=$true,
HelpMessage="SQLServer-Name?",Position=0)]
[String]
[ValidateNotNullOrEmpty()]
$ServerName = $(throw "sqlserver parameter is required.")
$Paths = "DEV_1", "DEV_2", "DEV_3"
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null
$objSQLConnection = New-Object System.Data.SqlClient.SqlConnection
$objSQLConnection.ConnectionString = "Server=$ServerName;Integrated Security=SSPI;"
$objSQLConnection.Open() #| Out-Null
foreach($path in $Paths)
$sqlSkripts = Join-Path ($PWD.Path) $path | dir -Filter "*.sql" | sort-object name
"sqlSkripts: " + $sqlSkripts
foreach($sqlSkript in $sqlSkripts)
$SQLCommandText = @(Get-Content -Path $sqlSkript.FullName)
"#" * $sqlSkript.FullName.Length | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
$sqlSkript.FullName | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
"#" * $sqlSkript.FullName.Length | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
Try
foreach($SQLString in $SQLCommandText)
if($SQLString -ne "go")
$SQLPacket += $SQLString + "`n"
else
$IsSQLErr = $false
try
$SQLCommand = New-Object System.Data.SqlClient.SqlCommand($SQLPacket, $objSQLConnection)
$SQLCommand.ExecuteScalar()
catch
Write-Host "Error..."
$IsSQLErr = $true
"SQLPaket: " + $SQLPacket
$SQLPacket | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
$Error[0] | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
$SQLPacket = $null
$SQLString = ""
Catch
$errText = $Error[0].ToString()
"Error: " + $errText | Out-File -FilePath ($PWD.Path + "\SQLProtokoll.txt") -Append
continue
$SQLCommandText = ""
$objSQLConnection.Close()
Write-Host "Done!..." -NoNewline
Thanks for your help

Hi Purclot,
How about using a parameter with the cmdlet $SqlCmdQueryPlanGet.Parameters.Add()?
I found a thread which has the similar issue may be helpful for you to modify the script:

I hope this helps.
