How to change table

[1Test3]

Hello, how to add new columns to the table after it's already been created by the first one?

table already created
if(!SQL::ExistsTable(SQL_PLAYERS_TABLE))
{
//If not, then create a table called 'players'.
new handle = SQL::Open(SQL::CREATE, SQL_PLAYERS_TABLE); //Opening a valid handle to create a table called 'players'
SQL::AddTableColumn(handle, "p_id", SQL_TYPE_INT, 11, true); //Setting auto-increment for this field.
SQL::AddTableColumn(handle, "p_name", SQL_TYPE_VCHAR, 24);
SQL::AddTableColumn(handle, "p_password", SQL_TYPE_VCHAR, 64);
SQL::AddTableColumn(handle, "p_score", SQL_TYPE_INT);
SQL::AddTableColumn(handle, "p_posx", SQL_TYPE_FLOAT);
SQL::AddTableColumn(handle, "p_posy", SQL_TYPE_FLOAT);
SQL::AddTableColumn(handle, "p_posz", SQL_TYPE_FLOAT);
SQL::Close(handle);//Closing the previous opened handle.
}

new field that needs to be added
SQL::AddTableColumn(handle, "health", SQL_TYPE_FLOAT);
