| function Remove-AccessColumn {
[CmdletBinding(SupportsShouldProcess=$true)]
param (
[string]$table,
[string]$column,
[System.Data.OleDb.OleDbConnection]$connection
)
$sql = "ALTER TABLE $table DROP COLUMN $column"
$cmd = New-Object System.Data.OleDb.OleDbCommand($sql, $connection)
if ($psCmdlet.ShouldProcess("$($connection.DataSource)", "$sql")){$cmd.ExecuteNonQuery()}
} |
We use the SupportsShouldProcess=$true to get the –whatif functionality. Parameters are table, column name and the connection.
We create the SQL and either run it or perform the –whatif processing. Remember we also get –confirm if we require it.
