You can do this in several ways. One method would use join with an explicit aggregation. However, because you only want one column, I think a correlated subquery is simpler to code: select t1.*, (select max(t2.value) from table2 t2 where t2.date between t1.date1 and t1.date2 ) as maxvalue from table1...

Use order by and limit: SELECT COUNT(*) AS count, field1, field2, field3 FROM someScheme.someTable GROUP BY field1, field2, field3 ORDER BY COUNT(*) DESC LIMIT 1; Note: this only returns one example of the maximum. If you want all possible rows, then it is more complicated: SELECT COUNT(*) AS count, field1,...

F# compares lists element by element. As 'B' > 'A' so it considers first list > second (lexicographic order) and breaks further comparison. You can use .Length property on list to compare lengths. Like this for example; let longest = if xs.Length > ys.Length then xs else ys Result: val...

One approach would be to store the previous two values lines in two variables, and use a third variable to store the line. So you could get the local minimum like this: awk 'prev!=""&&prev<=prev2&&prev<=$2{print line}{prev2=prev;prev=$2;line=$0}' file and the local maximum like this: awk 'prev!=""&&prev>=prev2&&prev>=$2{print line}{prev2=prev;prev=$2;line=$0}' file ...

you can remove the from numpy import * unless you are using it elsewhere. Aside from that using a list works fine. To get the max just call max(B) as follows: Z=int(raw_input("What is the atomic number?")) a1,a2,a3,a4 = 15.67,17.23,0.75,93.2 B = [] for A in range(Z, 3*Z): if A%2==1: a5=0...

There is no MAX or GROUP BY. It is just: SELECT TOP 1 cn.Note, cn.Date FROM CarsNote cn WHERE cn.CustomerID = '80' AND cn.Type = 'INFO' ORDER BY cn.Date desc; ...

Do a LEFT JOIN with a GROUP BY to find the MAX(timestamp): select e.empid, e.empname, e.status, max(timestamp) as lastusedts from employee e left join facilities f on e.empid = f.empid where e.status = 'active' group by e.empid, e.empname, e.status Alternatively, a correlated sub-select for the max-timestamp: select e.empid, e.empname, e.status,...
