12/28/2023 0 Comments Tableau prep builder calculated field![]() Returns the provided with the first letter of each word is capitalized and the remaining letters are in lowercase. MIN(expr1, expr2) compares the two values and returns a row-level value. ![]() This displays as AGG(expression) in the viz. MIN(expression) is an aggregate function and returns a single aggregated result. If MIN is a comparison, the result will retain the date hierarchy. If MIN is an aggregation, the result will not have a date hierarchy. MIN is usually the value that comes first in alphabetical order.įor database data sources, the MIN string value is lowest in the sort sequence defined by the database for that column.įor dates, the MIN is the earliest date. MIN can also be applied to a single field as an aggregation. ![]() MID("Calculation", 2) = "alculation" MID("Calculation", 2, 5) ="alcul" If the optional numeric argument length is added, the returned string includes only that number of characters. The first character in the string is position 1. Returns a string starting at the specified start position. MAX(expr1, expr2) compares the two values and returns a row-level value. MAX(expression) is an aggregate function and returns a single aggregated result. If MAX is a comparison, the result will retain the date hierarchy. If MAX is an aggregation, the result will not have a date hierarchy. MAX is usually the value that comes last in alphabetical order.įor database data sources, the MAX string value is highest in the sort sequence defined by the database for that column.įor dates, the MAX is the most recent date. MAX can also be applied to a single field as an aggregation. Returns the maximum of the two arguments, which must be of the same data type. Same data type as the argument, or NULL if any part of the argument is null. Returns the provided with any leading spaces removed. LOWER("ProductVersion") = "productversion" Returns the provided in all lowercase characters. Not to be confused with the spatial function (Link opens in a new window) LENGTH. ![]() Returns the left-most of characters in the string. Returns the position of the nth occurrence of substring within the specified string, where n is defined by the occurrence argument.įINDNTH is not available for all data sources. If the optional numeric argument start is added, the function ignores any instances of substring that appear before the starting position.įIND("Calculation", "alcu") = 2 FIND("Calculation", "Computer") = 0 FIND("Calculation", "a", 3) = 7 FIND("Calculation", "a", 2) = 2 FIND("Calculation", "a", 8) = 0 Returns the index position of substring in string, or 0 if the substring isn't found. See also the supported RegEx in the additional functions documentation (Link opens in a new window). Returns true if the given string ends with the specified substring. See also the logical function (Link opens in a new window) IN as well as supported RegEx in the additional functions documentation (Link opens in a new window). Returns true if the given string contains the specified substring. This is the inverse of the ASCII function. Returns the character encoded by the ASCII code. This is the inverse of the CHAR function. Returns the ASCII code for the first character of a. String functions available in Tableau ASCII Syntax Therefore, SPLIT('Jane Johnson', ' ', 2) = 'Johnson'. The calculation might look something like this: You can pull the last names from all your customers into a new field using a string function. The way strings are sorted and compared is based both on language and locale, and it’s possible for vizzes to change as the ICU is continuously updated for better language support.įor example, you might have a field that contains all of your customers' first and last names. Tableau uses the current International Components for Unicode (ICU) library when comparing strings. String functions allow you to manipulate string data (i.e. It also demonstrates how to create a string calculation using an example. This article introduces string functions and their uses in Tableau.
