TSQL: combination of two table
-1
I have 2 tables
A
EmpID IDcard Date
xxx 111 2018-10-01
zzz 111 2018-05-01
B
Idcard AgrNumb Date
111 x46 2018-10-01
111 x35 2018-05-01
111 x20 2017-12-01
111 x42 2018-08-01
I would like to make table in which I will have one row from the first table and one from the second table. Row from the second table should be the first row which is smaller from the date in first row. It should looks this way:
IDcard Date
111 2018-10-01 --> table A
111 2018-08-01 --> table B
111 2018-05-01 --> table A
111 2017-12-01 --> table B
I don't know how to do this. Can you help me?

it is unclear that exactly is your expected outcome. I could not derive it from the result. What are the criteria, how the rows are selected (e.g. why is the 4th rsult line the 3rd row from table B?)? and why do you want to interleave the tables? this is rather unusual and let me guess, that your data base design is awkward and should be reworked.

Can you try(if in sql-server):
Select T2.*, EmpID from Table1 T1
outer apply(
select t2_in.idCard, min(date) as DateT2
from table2 t2_in
where t2_in.idCard = t1.IDcard
group by t2_in.idCard
)t2

It doesnt work well. Now I get min(date) from B but I need smaller date than that in A but the biggest from the table B. And I need to this for each row seperate.
