Hello Guys, I am a beginner to SAP HANA.

I have a sql query something like this:

Select a.username,b.rask_id, count(*)

from tableA a, tableB b

where = tableB.doc_id

group by a.username, b.rask_id; relation with tableB.doc_id is 1:n.

Output of the above query is something like this:

user1 20

user2 1

userxxx 12

userN x

Can someone please help me how to create equivalent view for the above query?.

    Hello Muks,

    I think your question is how you can do that with a column view (calculation view/analytic view) and not with a "classic" database view?

    Within a calculaiton view (or analytic view) you can join both tables with a join node. To get the counter information you can

    1) use the "count" aggregation functionality in an aggregation node


    2) define a calculated column in a projection node after the join node which returns always the integer value 1 -> in the aggregation node you can use the "sum" aggregation functionality for that new column to get the count.

    Best regards,

      Thanks a lot Florian 😊.

      I tried with 2nd option and it worked. But the 1st option didn't. Can you please elaborate option 1. i.e. use "count" aggregation functionality.

      Basically when I use analytic view and add field "user" to output, I can use "count" aggregation on user but then I don't get the desired output. what i want is something like this:

      userName Count

      user1 10

      user2 2

      user3 5

      What I get is





      I want userName along with Count.
