This section lists all functions that can be used to create calculated fields and measures in Ad Hoc views.
Name | Description | Example | ||
|---|---|---|---|---|
Absolute | Returns the absolute value of a number or field, that is, the non-negative value of the number. | Absolute("Transaction Amount") - Shows the magnitude of each transaction, regardless of whether the transaction is positive or negative. | ||
Average | Returns the average value of a measure or numeric field, based on an optional level. Null values are not included. | Average("Salary," 'RowGroup') | ||
| Boolean ('StringExpression') | Casting function that takes a String expression and converts it to a Boolean data type. The String can be any expression that returns a supported string, including a field value or an attribute retrieved with the Attribute() function. The Boolean() function requires one of the following Strings: true, false, True, False, TRUE, or FALSE. Other Strings will return an error. | Boolean('true') | ||
Case | Takes 2N+1 or 2N+2 arguments: an expression followed by one or more value expression/return expression pairs, with an optional final return expression. Compares the expression in the first argument to each value expression in order of appearance. Returns the value of the expression immediately following the first value expression that matches. If no expression matches, returns the final DefaultReturnExpression if present, null otherwise. The types of all the return expressions must be compatible. For example, you can't mix numeric and text return value types. | Case("Shipped by", 1, 'FedEx', 2, 'UPS', 3, 'USPS', 'Unknown') | ||
CaseRange | Takes 2N+1 or 2N+2 arguments: an expression followed by one or more numeric expression/return expression pairs, with an optional final return expression. Finds the first numeric expression that is greater than the input expression and returns the value of the corresponding return expression. If no expression is greater, returns the final DefaultReturnExpression if present, null otherwise. The types of all the return expressions must be compatible. For example, you can't mix numeric and text return value types. | Case("Temperature", 60, 'too cold', 80, 'just right', 'too hot') CaseRange(CountAll("Shipping charge") % CountAll("Shipping charge", 'Total'), 2.0, 'Less than 2%', 5.0, '2% - 5%', 'More than 5%') | ||
CaseWhen | Takes 2N or 2N+1 arguments: one or more pairs of Boolean expressions followed by return expressions, with an optional final return expression. Returns the expression immediately following the first true Boolean expression. If no expression is true, returns the final DefaultReturnExpression if present, null otherwise. This is the most flexible construct. The types of all the return expressions must be compatible. For example, you can't mix numeric and text return value types. | CaseWhen("Shipped by" == 1, 'FedEx', "Shipped by" == 2, 'UPS', "Shipped by"== 3, 'USPS', 'Unknown') Case("Temperature" <= 60, 'too cold', "Temperature" > 80, 'too hot', 'just right') | ||
Concatenate | Combines muiltiple text strings and/or fields into a single text field. Text strings are enclosed in single quotes; labels for fields or measures in Ad Hoc are enclosed in straight quotes. | Concatenate("Last Name", ' , ' , "First Name") Concatenate("Product Category", '--', "Product Name") | ||
Contains | Boolean that returns true if the first string contains the second, false otherwise. | Contains("Product Name", 'Soda') | ||
CountAll | Returns the count of non-null items in a field or measure; note that CountAllalways returns a non-negative integer. Level can be one of the following: Current(default), ColumnGroup, ColumnTotal, RowGroup, RowTotal, Total. | CountAll("Transaction Amount", 'RowGroup')— Counts the total number of non-null transactions in the specified group. | ||
CountDistinct | Returns the distinct count of non-null items in the input. Always returns a non-negative integer. Level can be one of the following: Current(default), ColumnGroup, ColumnTotal, RowGroup, RowTotal, Total. | CountDistinct("Customer Name", 'Total')— Counts the number of distinct customers. | ||
Date ('StringExpression') | Casting function that takes a String expression and converts it to a Date data type. The String can be any expression that returns a supported string, including a field value or an attribute retrieved with the Attribute() function. The Date() function requires a String value formatted as 'yyyy-MM-dd'. Other Strings will return an error. | Date('2015-07-17') | ||
Decimal ('StringExpression') | Casting function that takes a String expression and converts it to a Decimal data type. The String can be any expression that returns a supported string, including a field value or an attribute retrieved with the Attribute() function. The Decimal() function requires a String value in decimal format, for example, '123.45'. Other Strings will return an error. | Decimal('1234.567') | ||
DayName | Given a date field, returns a text field with the name of the day of the week. | DayName("Open Date")— Displays the day of the week on which a store was opened. | ||

ElapsedYears | Calculates the number of years between two date fields. | ElapsedYears("Date shipped","Date required") | ||
EndsWith | Boolean that returns true if the first text input ends with the string specified in the second input; false otherwise. | EndsWith("Product Name", 's') | ||
IF | Given a Boolean field or calculation as the first argument, returns the second argument if true; optionally returns the third argument if false. Returns null if the first argument is null. | IF(Contains("Product Name", 'Soda'), 'Yes', 'No')— Uses the Contains function to see whether the product name | ||
| Integer ('StringExpression') | Casting function that takes a String expression and converts it to a Integer data type. The String can be any expression that returns a supported string, including a field value or an attribute retrieved with the Attribute() function.
