我尝试限制但说:ERROR 1235 (42000): 这个版本的 MySQL 还不支持 'LIMIT &IN/ALL/ANY/SOME 子查询'我只需要查询一个 imc_kg_m2 值但最近创建的

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,
    enfermedades.antiht = 0,
    enfermedades.diabetes = 1
where
    enfermedades.riesgo_diabetes_mellitus = 1
        and pacientes.situacion = 0
        and riesgo_diabetes_dano_organo_blanco = 0
        and signos_sintomas.created in (select 
            signos_sintomas.created
        from
            signos_sintomas
                join
            consultas ON consultas.id = signos_sintomas.consulta_id
                join
            pacientes ON pacientes.id = consultas.paciente_id
        where
            pacientes.id = pacientes.id
        order by signos_sintomas.created , consultas.created desc);

值 null 我很自然，我需要更新 enfermedades 中最近的 imc_kg_m2

the values null i'ts natural by i'm need the recent imc_kg_m2 in the update enfermedades

我开始怀疑这样的咨询不能解决我的问题，依赖关系和现在存在的关系，我不能做任何其他方式来改变它会影响我的模型和视图模型.

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.

推荐答案

我不确定我是否完全理解目标，但我试了一下......

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));

为了解决这个错误，我为子查询设置了别名并加入了它们.我删除了一个，因为我无法弄清楚它为什么在那里.我还添加了 where 来执行您要求的操作.如果它不符合您的要求，请发表评论.

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.
