Hi All

Have answered most of the questions(Most of them are copied from the reference manual :-)). But it will be helpful for someone who need the most. Few not yet answered requesting someone to give answer for that.

1. What is the difference between Set and Let?

Ans:

Set:

Script variables are entities that can be assigned any text or numeric value. When used, the variable is substituted by its value. Variables can be used in the script for macro expansion and in various control statements. This is very useful if the same string is repeated many times in the script, e.g. a path.

set variablename = string

Let:

The let statement has been created as a complement to the set statement, used for defining script variables. The let statement, in opposition to the set statement, evaluates the expression on the right side of the ' =' before it is assigned to the macro variable.

let variable = expression

2. How many dimensions can be used in Bar chart?

Ans:

Two

3.Which Qlikview object has only expression, no dimension?

Ans:

List Box, Gauge Chart

4.What is the difference between Concatenate Load and Join?

5. Incremental Load

Ans:

Incremental load is a very common task in relation to data bases. It is defined as loading
only the new or changed records from the database. The rest should already be
available, one way or another.

6. Synthetic keys . How to remove them

Ans:

Renaming,Concatanating the field by creating KEY field and use Qualify Statement

7. What is Circular reference? How to avoid them?

Ans:

A structure in the data model where the keys
between at least three tables form a circle. The
logic then inferred is usually ambiguous and the
circlular reference needs to be broken. QlikView
does this by setting one of the tables as loosely
coupled.

8. Have you used any macros in your application? If so, what you have used it for.

Ans:

We can use macros for various things as follows

1. We can all the macro to reload the application.

2. We can call the macro to create the objects.

3. ....

9. What is Set Analysis ( benefits of using it)? Why its called Set Analysis

Ans:

Sets can be used in aggregation functions. Aggregation functions normally aggregate over the set of possible records defined by the current selection. But an alternative set of records can be defined by a set expression. Hence, a set is conceptually similar to a selection.

A set expression always begins and ends with curly brackets when used, e.g. {BM01}.

10. Difference between Qlikview version 9 SR 6 and previous other Qlikview 9 versions?

11. What is the use of exists function in qlikview?

Ans:

exists( field [ , expression ] )
Determines whether a specific field value exists in a specified field of the data loaded so far. Field is a name or a string expression evaluating to a field name. The field must exist in the data loaded so far by the script. Expr is an expression evaluating to the field value to look for in the specified field. If omitted, the current record’s value in the specified field will be assumed.

4.What is the difference between Concatenate Load and Join?

Ans: Join and Concatenate can be used to tackle the same kind of situation, but there is a difference which should be understood.

Join will combine the rows where the key values matches, but OUTER keyword along with join also combines where key values doesn't match.

Concatenate appends the rows of one table to another. Concatenate never merges any rows. The number of rows in a concatenated table is always the sum of the rows from the two input tables.

Note: Concatenate can be forced even though there are no common field set in the two tables.
