How can unnecessary columns be removed from MySQL query results in PowerShell when using convert-tohtml?

edit

To remove unnecessary columns from a MySQL query result in PowerShell when using convert-tohtml, you can use the "select" keyword to specify only the required columns. Here's an example:

# Connect to MySQL database
$connectionString = "server=localhost;port=3306;database=mydatabase;uid=myusername;pwd=mypassword;"
$connection = New-Object MySql.Data.MySqlClient.MySqlConnection($connectionString)
$connection.Open()

# Query the database and convert result to HTML
$query = "SELECT column1, column2 FROM mytable"
$command = New-Object MySql.Data.MySqlClient.MySqlCommand($query, $connection)
$result = $command.ExecuteReader()
$table = New-Object System.Data.DataTable
$table.Load($result)
$htmlTable = $table | Select-Object column1, column2 | ConvertTo-Html -As Table

# Output the HTML table
$htmlTable

In the above example, the "select-object" keyword is used to select only the "column1" and "column2" columns from the query result, and these columns are then passed to the "convert-tohtml" cmdlet to generate an HTML table.
