invoke-sqlcmd : Error converting data type varchar to numeric

Hello,

I try to collect dbspace with ps script :

-The table ddl and the ps script are  :

CREATE TABLE [dbo].[DSpace](
	[SERVERNAME] [varchar](50) NULL,
	[DatabaseName] [varchar](128) NULL,
	[Log_filename] [varchar](128) NULL,
	[Log_filesize] [decimal](18, 2) NULL,
	[Used_space] [decimal](18, 2) NULL
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

    $SQLInstance = "SQLTEST"

    $srv = new-object ('Microsoft.SqlServer.Management.Smo.Server') $SQLInstance

    $DBStats = $srv.Databases
		

        foreach ($DB in $DBStats) {
		IF ( $DB.status -eq "Normal" ) {
		$DBName = $DB.Name
		$db.get_logfiles() | % { New-Object PsObject -Property @{
		'Log File' = $_.FileName
		'Size (MB)' = [math]::round($_.Size/1KB,2)
		'Used Space (MB)' = [math]::round($_.UsedSpace/1KB,2)
		} | tee -Variable vals | Format-Table -auto
		
		$val.{Log File} 
		$val.{Size (MB)} 
		$val.{Used Space (MB)} 
	
		}
        $InsertResults = @"
   
		INSERT INTO DSpace (SERVERNAME ,DatabaseName ,Log_filename ,Log_filesize ,Used_space)
		VALUES ('$SQLInstance', '$DBName', '$val.{Log File}', '$val.{Size (MB)}', '$val.{Used Space (MB)}')
		
		"@
		

        invoke-sqlcmd @params -Query $InsertResults

		}
	}

Open in new window

The error returned is :
invoke-sqlcmd : Error converting data type varchar to numeric.
At line:20 char:9
+         invoke-sqlcmd @params -Query $InsertResults

    + CategoryInfo          : InvalidOperation: (:) [Invoke-Sqlcmd], SqlPowerShellSqlExecutionException
    + FullyQualifiedErrorId : SqlError,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand

How can I resolve this problem ?

Thanks

Remove the single quotes inside the INSERT statement for all numeric values, and you need to make them a subexpression inside of double quotes.
But there is another issue - if $DB.status is not "Normal", you still try to insert values, which are not recent by then - the INSERT belongs into the IF block.
And there is a typo in the tee-object, so the wrong variable is filled.
CREATE TABLE [dbo].[DSpace](
	[SERVERNAME] [varchar](50) NULL,
	[DatabaseName] [varchar](128) NULL,
	[Log_filename] [varchar](128) NULL,
	[Log_filesize] [decimal](18, 2) NULL,
	[Used_space] [decimal](18, 2) NULL
) ON [PRIMARY]

$SQLInstance = "SQLTEST"

$srv = new-object ('Microsoft.SqlServer.Management.Smo.Server') $SQLInstance

$DBStats = $srv.Databases
		

foreach ($DB in $DBStats) {
  IF ( $DB.status -eq "Normal" ) {
    $DBName = $DB.Name
    $db.get_logfiles() | % { New-Object PsObject -Property @{

    } | tee -Variable val | Format-Table -auto

In your code you wrote the following:
tee -Variable vals

Is that val instead?

Can't find any issue. Please add this before or after line 34 for debugging:
Write-Host $InsertResults

There is a syntax error in my code - a closing curly bracket missing. But that should have errored out pre-execution anything ...
foreach ($DB in $DBStats) {
  IF ( $DB.status -eq "Normal" ) {
    $DBName = $DB.Name
    $db.get_logfiles() | % {
      New-Object PsObject -Property @{
        'Log File' = $_.FileName
        'Size (MB)' = [math]::round($_.Size/1KB,2)
        'Used Space (MB)' = [math]::round($_.UsedSpace/1KB,2)
      } | tee -Variable val | Format-Table -auto

      $InsertResults = @"
        INSERT INTO DSpace (SERVERNAME    , DatabaseName, Log_filename ,Log_filesize ,Used_space)
                    VALUES ('$SQLInstance', '$DBName'   , '$($val.{Log File})', $($val.{Size (MB)}), $($val.{Used Space (MB)}))	
"@
      
      invoke-sqlcmd @params -Query $InsertResults
    }
  }
}

I've left the Format-Table as-is but it isn't what I would use - it is called for each line individually, insteadl of all the results together. On the other hand, if I change that, you won't see any intermediate results unless script execution is completed.
