Select encadeado

Bom pessoal,

Tenho tres consultas distintas que so muda a faixa de hora, porem quero que ela seja um unico select, exemplo:

Data | Cafe | Almoço | Jantar
21/12/12 | 15 | 62 | 36

Esses sao os comandos separados:

select CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) AS Data, count(mov_datahora) AS CAFE from log_credencial
where mov_datahora between '20121201' and '20121216'
and mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) > '05:30'
AND mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) < '08:00'
and eqpi_numero = 2
group by CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime)

select CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) AS Data, count(mov_datahora) AS ALMOÇO from log_credencial
where mov_datahora between '20121201' and '20121216'
and mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) > '10:30'
AND mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) < '14:00'
and eqpi_numero = 2
group by CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime)

select CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) AS Data, count(mov_datahora) AS JANTAR from log_credencial
where mov_datahora between '20121201' and '20121216'
and mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) > '18:00'
AND mov_datahora - CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime) < '20:00'
and eqpi_numero = 2
group by CAST(FLOOR(CAST(mov_datahora AS float)) AS datetime)

Alguem pode me ajudar?
