Hi,

Even though some functions/syntax may seem similar among Qlik and SQL they're quite different in the way the work. So translating a query from SQL to Qlik sometimes could be a bad idea.

Instead, the approach I would recommend is to use the SQL query that you already have and extract it in Qlik Sense. You can execute almost any SQL query in QlikView / Qlik Sense, you just have to follow this structure in the data load editor:

[Qlik Table]:

Load *, Field1 + Field2 as Field3; //ADDITIONALLY YOU CAN ADD NEW FIELDS WITH QLIK SYNTAX

SQL Select Field1, Field2, Field N

from db.user.table

WHERE MST.VNO=DTL.VNO

AND DTL.ACID=COA.ID

AND ID IN (SELECT ID FROM NGL_COA START WITH ID='20000000' CONNECT BY PRIOR ID=PACID)

Everything after keyword "SQL" can be any SQL Query, and the way it works is that Qlik sends the query to the database manager and then just receives the result.

So you can combine SQL queries with Qlik Syntax just like in the above example

hope this helps,

If you like want to learn more about qlikview I would recommend you the book "QlikView for developers" by Harry Harmsen and Miguel García. By reading and following the exercises you'll learn in general terms what (and some best practices) can be done with qlikview in a real project. The rest is just experience and practice,

hope this helps,
