QlikView Script has many sections which are mandatory Just like load script, Expressions, Script expressions, variables, Number Interpretation. In that, some of them were optional Options like variables and master calendar. One of the common Feature that you see every time in this script is changing and reassigning of Fields. Like QUALIFY, Table, Filed/Rename, Rename, AS, Alias). The Renaming of Fields is like a Typical Feature of Scripts.

Number Interpretations Variables

The thing you have to notice when opening the code Editor, for a latest Qlikview File. Is the count Interpretation variables. Many of these variables include how many numbers, date, time, currency were managed and displayed. It populated by inbuilt, when Designing latest Qlik view file. When a Qlikview script is operated, these variables override with Similar settings from computer OS with business Intelligence software.

Similarly, I will show an example of Interpretation Variables in every code. As a result Every Set statement will define a variable like Comma (,) for variable Thousands, that divide numeric thousands. Master this with guidance of online courses.


SET ThosandSep= ‘,’:

SET DecimaLSep= ‘-’;

SET MoneyThousandSep= ‘,’;

SET MoneyDecimaLSep=‘-’;

SET MoneyFormat=‘$#,##0.00;($#,##0.00)’;

SET TimeFormat=‘h:mm:ss TT’;

SET DateFormat=‘M/D/YYYY’;

SET TimesStampFormat=‘M/D/YYYY h:mm:ss[.fff] TT’;

SET DayNames=‘Mon;Tue;wed;Thu;Fri;Sat;Sun’;

We can edit Number Interpretation variables, (We have to click on Gray hammer icon to left of Set Statement corresponding to every variable). Here you can add many Interpretation variables by using Insert | Set statement menu command in script Editor for open source BI.

Script Expressions

Generally, QlikView chart Expressions were used in Front end Chart Objects in Qlikview. However, the code Expressions used in Qlik view command by itself. Script Expressions contain scripting Functions, operators and fields. Most used code Functions contain aggregation functions and Inter record functions. You may also view financial Functions and Statistical Functions. However, these functions are common in front end chart Expressions. Some common Functions include String functions, Interpretation, Numeric, Conditional, time and Date, counter.

Small Information about Qlikview dashboard terminology. Concept Fields refer to Information columns in table. In that, they have records, which they refer to rows in a table. Records and Fields have in documents like DVDs. Operators classify as numeric operators, bit operators, string, logic, relational, bit operators.

Script Expressions will return in number or string, or both of them. Logical code Expressions and operators were return to Zero (0) for false or -one, and for true. Expression change to numbers, where numbers change to strings.

Quotation Marks

Usability of Quotation marks in Qlikview syntax little bit tricky. It Depend on your Referencing Variables, values, and fields. Usually, quotations initiated for field values, that inside of Load Statement. You have to make a note of Quotation Marks that were in “Select” Statements. To enumerate these Statements vary, depending on method of Information Source and ODBC/OLE DB driver like. Oracle, DB2, MySQL, Interpret quotation marks and many more. For this, we have some basic guidelines and rules to follow quotation marks in Qlikview community Load statements.

Single Quotes work with Reference Literal Values. Most important these values just like string of numbers or text that used as field values.

Source Information field names inside Load Statements that mostly use Double quotes. As a matter of fact field names usually found to left and AS specifier in a Load Statement.

In the meantime, we can use Square brackets instead of Double Quotes.

Every time Developers Do a common mistake, when they use a field name. It contain a character like space or dash. Here you have to use double bracket or Quote.

For Instance, if you have an Information source, in particular field name with a space in it known as “Client ID”, then…

Load Client ID

Generally, it will cause a script Error, since Qlikview expect as AS Specifier, or just like a comma after the word client. Usually correct Syntax is usability brackets or double quotes like

Load [Client ID]


Load “client ID”

What happen, when you use a single Quote? If you write in your code:

Load ‘client ID’

The text String Client ID, it will interpret it by QlikView just like a literal field value.

While quotation marks outside a load statement, double quotes signal qlikview to look for a variable. As an illustration, which is not, a source field name. Simultaneously Outside of a Load Statement, specifically the string inside double quotes will interpret them as a variable reference. Equally important total value of variable will be utilized here.

Out of context field references and table references like parameters in it peek (), NoOfRows(), in addition Exists required for Single Quotes and Literal Values.

Qlikview allows usability of Quotation brackets and marks in so many places like.

Starting parameter of Peek(), Exists() inside load statements

Definitions, which regard Inline Tables.

File Names, URLs, external tables names.

Aliases in load Statement, that is right of AS.

Combination statement definitions that is to right of Equals sign.
Master calendar Placement

Especially One Script Concept that declared in mater calendars. Just like time-period tables, that connected with fact tables. As a master calendar, to enumerate it is very powerful in fact tables. Because it do not depend on dates in fact table by itself. As there may be dates in table by itself, or for No information that available for selecting if no Information is existed. In the same way, a business intelligence analyst can master it easily.

To illustrate Master calendar designs with total calendar, that usually by watching at minimum transaction date in fact table. However, Auto populating Dates for a sequence ending at final transaction date or present Date. In addition, Master calendar is tougher for first or second tab in a code and it located on its own local tab. Moreover for a simple editing and reference drill down.

Finally, Master Calendars were easy to code, but we have third parties for designing master calendar Script designs. Not to mention Space do not accept us to reach inside master calendars. Enroll for Qlikview training and get any Business Intelligence technology self-paced videos free.
