Could you point a tool, considering it exists, that could transform a complex query to a MER diagram by using MSSQLServer?

Hi Experts

Could you point a tool, considering it exists, that could transform a complex query to a MER diagram?

Actually I'm doing surveys on a legate system to migrate the data contents to what will be  its correspondents on a CRM.

The queries is quite complex at first view.

SELECT * FROM ( SELECT at.id_atendimento, a.nome_assistido, 
      ELSE '' END, c.contato) 
  FROM XXX.dbo.contato as c WHERE c.ativo_sn = 'S' 
    AND c.id_assistido = a.id_assistido 
    AND a.cpf <> CONCAT(CASE WHEN c.ddd > 0 THEN CAST(c.ddd AS VARCHAR) COLLATE SQL_Latin1_General_CP850_CI_AI ELSE '' END, c.contato) 
  ORDER BY ddd DESC, c.principal_sn DESC ) AS contato, 
  ol.descricao AS origem_ligacao, 
  (CASE WHEN a.id_titular IS NULL THEN 'R' ELSE 'D' END) AS tipo_usuario, 
    a.id_titular, at.id_usuario, at.id_servico, at.stamp_inicio_atendimento, 
    at.stamp_fim_atendimento, a.matricula, sni.id_solicitacao_novo_item, sni.id_tipo_status_solicitacao_novo_item, 
    sni.id_tipo_item_finalizado, aa.observacoes, aa.data_agendamento, a.cpf, pat.id_produto, at.atendimento_adverso, 
    at.id_tipo_responsavel, at.id_tipo_relacao, at.nome_responsavel, g.gerenciador, at.id_usuarioematendimento, 
    at.dataematendimento, at.divergencia_farmacia_sn, at.id_ligacao, at.motivo_contato, at.atendimento_em_aberto_sn, 
    at.semcontinuidade_sn, at.id_assistido, at.id_cliente, p.descricao as desc_produto, at.protocolo_atendimento, 
  (SELECT TOP 1 id_tipo_status_solicitacao_novo_item AS ultimo_status FROM XXX.dbo.solicitacao_novo_item AS subSni 
      WHERE subSni.id_atendimento = at.id_atendimento 
  ORDER BY subSni.id_solicitacao_novo_item DESC) AS id_ultimo_status, 
  ROW_NUMBER() OVER( ORDER BY (CASE WHEN aa.data_agendamento < DATEADD(minute,2,GETDATE()) THEN 1 
    WHEN aa.data_agendamento IS NULL THEN 2 ELSE 3 END) ASC, aa.data_agendamento DESC, 
          at.stamp_inicio_atendimento ASC, a.nome_assistido ) AS RowNr FROM XXX.dbo.assistido AS a 
        INNER JOIN XXX.dbo.atendimento AS at ON (at.id_assistido = a.id_assistido) 
        LEFT JOIN XXX.dbo.solicitacao_novo_item AS sni ON (sni.id_atendimento = at.id_atendimento) 
        LEFT JOIN XXX.dbo.gerenciador AS g ON (g.id_gerenciador = at.id_gerenciador) 
        LEFT JOIN XXX.dbo.atendimento_agenda AS aa ON (aa.id_atendimento = at.id_atendimento AND aa.ativo_sn = 'S') 
        LEFT JOIN XXX.dbo.produto_atendimento AS pat ON (pat.id_atendimento = at.id_atendimento) 
        LEFT JOIN XXX.dbo.produtos AS p ON (p.id_produto = pat.id_produto) 
        LEFT JOIN XXX.dbo.origens_ligacao AS ol ON (ol.id_origem_ligacao = at.id_origem_ligacao) 
  WHERE at.ativo_sn = 'S' AND at.atendimento_realizado_sn = 'S' AND at.stamp_inicio_atendimento <= '20190321 23:59:59' AND at.stamp_fim_atendimento IS NULL ) AS tempTable 
  WHERE 1 = 1 AND RowNr BETWEEN 1 AND 20 
  ORDER BY tempTable.id_atendimento DESC, tempTable.i d_solicitacao_novo_item DESC, tempTable.id_tipo_status_solicitacao_novo_item DESC
