A data architect executes the following script: Which values does the OrderDate field contain after executing the script?
Correct Answer: D
In the script provided, the alt() function is used to handle various date formats. The alt() function in Qlik Sense evaluates a list of expressions and returns the first valid expression. If none of the expressions are valid, it returns the last argument provided (in this case, '31/12/2022'). Step-by-step breakdown: * The alt() function checks the Date field for three different formats: * YYYYMMDD * YYYY/MM/DD * DD/MM/YYYY * If none of these formats match the value in the Date field, the default date '31/12/2022' is assigned. Values in the Date field: * 20210131: Matches the first format YYYYMMDD. * 2020/01/31: Matches the second format YYYY/MM/DD. * 31/01/2019: Matches the third format DD/MM/YYYY. * 9999: Does not match any of the formats, so the alt() function returns the default value '31/12/2022'.
