I try to make a limit but Say: ERROR 1235 (42000): This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery' i need the query only one imc_kg_m2 value but most recent created
update pacientes
join
enfermedades ON pacientes.id = enfermedades.paciente_id
join
consultas ON consultas.paciente_id = pacientes.id
join
signos_sintomas ON signos_sintomas.consulta_id = consultas.id
set
bmi = signos_sintomas.imc_kg_m2,
enfermedades.promedio_presion_sistolica = ((pa_de_pie_izquierda + pa_sentado_izquierda) / 2),
enfermedades.microalbuminuria = 0,
enfermedades.macroalbuminuria = 0,
enfermedades.fibrilacion = 0,
enfermedades.ecv = 0,
enfermedades.duracion = 15,

join
consultas ON consultas.id = signos_sintomas.consulta_id
join

where

order by signos_sintomas.created , consultas.created desc);
the values null i'ts natural by i'm need the recent imc_kg_m2 in the update enfermedades

I begin to suspect that such consultation is not the solution to my problem, dependencies and the relationship that exists right now, I can not do it any other way to change it would affect me the model and the view model.
回答1:
Not sure I totally understand the aim, but I had a go...
select
consultas.id as a,
consultas.clasificacion as cl,
consultas.paciente_id as b,
consultas.created,
imc_kg_m2 as im
from consultas
join signos_sintomas on signos_sintomas.consulta_id = consultas.id
join (select pacientes.id from pacientes where pacientes.id < 30) p on consultas.paciente_id = p.id
where imc_kg_m2 = (select imc_kg_m2 from consultas where created = (select max(created) from consultas where imc_kg_m2 is not null));
To resolve the error I aliased the subqueries and joined them instead. I removed one because I couldn't work out why it was there. I also added the where to do something like what you are requesting. Comment if it doesn't do what you want.
