mysql - Get data where MAX(date) < X -

-

i have 2 tables one-to-many relationship. 

table1 id name email table2 id table1_id date

i need data table1 where :

max(date) table2 < "2016-01-01"

this doesn't work. max considered "invalid" in clause. did : 

select table1.name, table1.email, tmp.maxdate table1 join (  select  max(date) maxdate, table1_id            table2         group table1_id ) tmp     on  tmp.table1_id = table1.id   tmp.maxdate < "2016-01-01" ,     (other conditions)

so works. think performance going awful - explain shows table2 being read, , table grow lot.

any idea on how otherwise, or how improve current query performances ?

try:

select table1.name, table1.email, tmp.maxdate table1 inner join (  select  max(date) maxdate, table1_id            table2         group table1_id         having maxdate > "2016-01-01" ) tmp     on  tmp.table1_id = table1.id    ,     (other conditions)

before, bringing table2 , join table1. knock off without maxdate > "2016-01-01" , join on table1.
