Is there any negative effect to setting SqlCommand's CommandTimeout to a high value?

public SqlCommand GetCommandObj()
{
        SqlCommand cmd=new SqlCommand();
        cmd.CommandTimeout=60;
        cmd.CommandText="your query here";
        return cmd;
}

int rowCount = 0; // In case you want the number of rows affected

try
{
    if (conn.State != ConnectionState.Open)
        conn.Open();

    MySqlCommand command = new MySqlCommand(query, conn);   

    using(var transaction = conn.BeginTransaction(iLevel))
    {   
        command.Transaction = transaction;                 
        command.CommandTimeout = int.MaxValue;

        // Set parameters etc...

        try
        {
            rowCount = command.ExecuteNonQuery();
            transaction.Commit();
        }
        catch(Exception ex)
        {
            transaction.Rollback();         
            // Handle query exception...            
        }
    }
}
catch(Exception ex)
{
    // Handle general exception...
}
