Managing Error
It’s essential to have a mechanism in place to handle errors when they occur. Here’s an example of how you can manage errors in PowerShell:
1 2 3 4 5 6 7 8 9 10 | try { # Code that can generate an error $connectionString = "Server=$dataSource;uid=$user; pwd=$PassSQL;Database=$database; Integrated Security=False;" $connection = New-Object System.Data.SqlClient.SqlConnection $connection.ConnectionString = $connectionString $connection.Open()} catch { # if there's an error in the try, this code will be used Write-Host $_.Exception.Message -ForegroundColor Red} |
