Hello I have a little problem regarding my error logging to SQL from powershell scripts.
function Invoke-Sqlcmd {
param(
[Parameter(Position=0, Mandatory=$true ,ValueFromPipeline = $false)] [string]$ServerInstance,
[Parameter(Position=1, Mandatory=$true ,ValueFromPipeline = $false)] [string]$Database,
[Parameter(Position=2, Mandatory=$false ,ValueFromPipeline = $false)] [string]$UserName,
[Parameter(Position=3, Mandatory=$false ,ValueFromPipeline = $false)] [string]$Password,
[Parameter(Position=4, Mandatory=$true ,ValueFromPipeline = $false)] [string]$Query,
[Parameter(Position=5, Mandatory=$false ,ValueFromPipeline = $false)] [Int32]$QueryTimeout=30
)
$conn=new-object System.Data.SqlClient.SQLConnection
if ($UserName -and $Password)
{ $conn.ConnectionString="Server={0};Database={1};User ID={2};Pwd={3}" -f $ServerInstance,$Database,$UserName,$Password }
else
{ $conn.ConnectionString="Server={0};Database={1};Integrated Security=True" -f $ServerInstance,$Database }
$conn.Open()
$cmd=new-object system.Data.SqlClient.SqlCommand($Query,$conn)
$cmd.CommandTimeout=$QueryTimeout
$ds=New-Object system.Data.DataSet
$da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
[void]$da.fill($ds)
$conn.Close()
$ds.Tables[0]
}
try {
ThisCommandDoesNotExist
}
catch {
$Exception = $_.Exception.Message
Invoke-Sqlcmd -Serverinstance mysqlserver -Database Mydatabase -Query "Insert into MyTable Values (GetDate(),'$Exception')"
}
The error I receive is:
Invoke-Sqlcmd: Exception calling "Fill with "1" argument(s): "Incorrect syntax near 'ThisCommandDoesNotExist'
I suppose it has something do to with the single quotes, I am no SQL expert. But I have tried doing a replace on all the "'" and "," and "." but still the same error is thrown.
Found the solution myself. At last it work when i did replace on .,:=
You are correct, the single-quotes makes powershell treat your $variable as a string.
You can escape powershell special characters by using the backtick ` .
