QlikView has many built-in functions, which are available to be applied to data that is already available in memory. These functions are organized into many categories and the syntax of the function appears as soon as it is selected. We can click on the Paste button to get the expression into the editor and supply the arguments.

Create Table Box

Create a Table Box by following the menu as shown in the screen shot given below.

On completing the above given step, we get a window to show the Calculation condition at the bottom left.

List of Functions

Click on the button next to calculation condition and go to the Function tab. It shows the list of functions available.

On choosing String from the functions category, we can see only few functions, which take a string as an argument.

QlikView – IntervalMatch

QlikView IntervalMatch is a powerful function used to match distinct numeric values to numeric intervals. It is useful in analyzing how the events actually happened versus the planned events. The example of a scenario where it is used is in the assembly lines of the production houses where the belts are planned to run at certain times and for certain duration. However, the actual run can happen at different points in time because of breakdown etc.

Example

Consider an assembly line where there are three belts named A, B and C. They are planned to start & stop at specific times of a day. In a given day, we study the actual start and end time and analyze what all happened in that day. For this, we consider two sets of observations as shown below.

# Data Set for AssembilyLine.

StartTime,EndTime, BeltNo

00:05,4:20, A

1:50,2:45,B

3:15,10:30,C

# Data set for the events happened.

ActualTime,Product

1:10,Start Belt A

2:24,Stop Belt A

3:25,Restart Belt A

4:35,Stop Belt A

2:20,Start Belt B

3:11, Stop Belt B

3:15,Start Belt C

11:20, Stop Belt C

Creating the Script

We open the script editor in a new QlikView document using Control+E. The following code creates the required tables as inline data. After creating this script, press control+R to reload the data into the QlikView document.

Creating Sheet Object

Let us create a Table Box sheet object to show the data generated by the IntervalMatch function. Go to the menu item Layout → New Sheet Object → Table Box. The following window appears in which we mention the Title of the table and select the required fields to be displayed.

Showing the Table Box

On clicking OK in the above window, a table appears showing the field ActualTime matched to the intervals StartTime and EndTime.
