Advance with Assist shares quick solutions to common challenges encountered by the InterWorks Assist on-demand team. Question: I need to add multiple layers of logic to Tableau, but I don't want multiple lines of Options and written. How can I use multiple IF statements? Logical calculations take many forms, and each of us probably has habits that affect the way we write calculations. This client's question has several possible solutions, but what we're going to focus on on this blog is nested logical statements. The basic format of an IF statement is: IF <insert logical= test=>THEN <some result=>ELSEIF.... More... NESTED END IF the statements simply add another IF layer after logical testing: IF <insert logical= test=>THEN IF THEN END <insert additional= logical=> <some result=>ELSEIF.... More... FINAL EXAMPLE OF NESTED IF calculations Nested calculations can be extremely useful when you need to identify different members of the same dimension for the purpose of giving different results to each member. I might want to identify segments and shipping modes and assign a specific color to Send Mode if it achieves a certain numeric goal. Using Sample Superstore data in Tableau that we're all probably familiar with, let's look at the Consumer over 300 Same Day: Using a nested IF, I could write the following calculation for our example: This calculation results in the following: Testing the logical scenarios of variables is a common task in data science and business intelligence. This allows us to determine whether a particular condition is true or false (Boolean logic), thus providing useful insights. In this guide, you'll learn how to create conditional calculations with functions built into Tableau. Conditional calculations can be applied in both dimensions and measures. This guide will use the Sample Superstore data source available in the tableau repository. In subsequent sections, you will implement several built-in functions, including IF, IFELSE, CASE, and ISDATE. The IIF function is used to return the true output if the expression is met, otherwise it returns false or null as output. The first step is to create a calculated field and name it iif example. Type the logic in the calculated field as shown below. Then drag subcategrate to the Columns and Sales shelf to the Rows shelf. Turn on the label to display the values. Then drag the calculated field IIF sample to the Marks Board Color option. The output above shows that the bar chart is demonstrating the color as specified in the logic. The IF function allows the user to construct only one condition, and if the condition is satisfied, the function returns the output. The THEN extended argument is used to return the result, given the expression in the IF part that is satisfied. To start, create a calculated field called if example write the logical expression as shown below. This expression only returns the Sales value if the category condition is satisfied. Drag the </some> </insert> <insert> </some> </insert> </insert> on the Lines shelf and in the calculated field, if example, in the Text option of the Marks shelf. The output above shows that the other two categories are blank, and sales are displayed only for the Technology category. This is an updated version of the previous IF THEN function. You can create two conditions using this function. To get started, create a calculated field called IF ELSE, for example, and type the logical expression as shown below. This expression returns the sales value when the condition is met, otherwise returns a value of zero. Then drag the category to the Lines shelf and the calculated field for the Text option of the Marks shelf. The output above shows that the sales value is displayed only for the Technology category. The CASE function evaluates the expression mentioned in the conditions, scans the values, and returns the value that corresponds to the expression. To begin, create a calculated field called Case E.g., and type the logical expression as shown below. The next step is to drag the category and the calculated field, Case E.g., to the Lines shelf. Also, place the Case variable For example in the Text option of the Marks shelf. This will generate the required output. In report design, Tableau If Function is one of the most useful decision-making functions. If the function tests the condition and, depending on the result of the condition, it returns the output. In Tableau, we have three variants of if functions: If, if not, ElseIf. In this article, we'll show you how to use these three functions with examples. For this Tableau If statement demo, we'll use the data in the Super Excel Global Spreadsheet so that you can please see Connect to Excel Files in the tableau article to understand the connection settings. Table if declaration exampleThe table if the declaration returns the result only if the given condition is true; otherwise, it returns nothing. To demonstrate this Tableau If function, we need a Calculated Field. To create a calculated field, navigate to the analysis tab and select the Calculated Creation Field... option, as shown below. Once you click the Calculated Create Field... option, the next window will open. Here, we rename the default calculation name as If Exam. And the isIF code ([Profit]) > 0) THEN 'Performing Good' ENDLet add this calculated field to the table (dragging a field to Rows Shelf) that we created earlier. See the Table Report article to understand the steps involved in creating a tableFrom a screenshot above, you can see, it is returning NULL values for the failure condition. To avoid this NULLS, you have to use Tableau IF ELSETableau If Else Function ExampleThe Tableau If Else function will test the condition. If the test condition is true, the statement after the THEN keyword returns if false, the statement after the Else keyword returns. Tableau If Other Syntax Syntax Frame If More in Tableau is as follows:SE <Expression> THEN </Expression> </Expression> ELSE <False_statement>ENDIn in this Tableau, if more calculation, let's check whether the Profit is greater than 0 or not. If the condition is TRUE, then Performing Good is returned If it is FALSE, The Bad Performance will store in the ifElse Exam fieldCode that we use for this Tableau if another isIF Statement ([Profit]) > 0) THEN 'Performing Good' ELSEE 'Bad Performance' ENDLet add this Tableau If Else calculated field to the tableTableau ElseIf Function ExampleThe Tableau ElseIf is useful for checking various conditions. Remember, ELSE SE conditions are only executed if it is earlier if the IF or ELSEIF statement fails. Tableau ElseIf Syntax syntax of If Else in Tableau is as follows:IF<Expression1>THEN <True_statement1>ELSEIF <Expression2>THEN <True_statement2>ESEIF <Expression3>THEN <True_statement3>..... ELSE <False_statement>ENDTableau It will check the first condition, if the condition is TRUE, it executes the statement after the THEN keyword. If false, it checks the next (ElseIf condition) and so on. Code we use to tableau if belowIF (SOMA([Profit]) > 60000000) NEXT 'Profit' ELSEIF (SOMA([Profit]) > 0) THEN 'Breakeven' ELSE 'Loss' ENDLet me add this Tableau If, if more and more if the Statement comes out to the existing table IN <expr1>IN TRUE Returns if any value <expr2>match any value in <expr1> <expr2>. The values <expr1>can be a set, list of literal values, or a combined field. Examples: SOMA([Cost]) IN (1000, 15, 200) [SET] IN [COMBINED FIELD] AND SE <expr1>E <expr2>AFTER <then>FIM Performs a logical conjunction in two expressions. Example: IF ([Market]) = Africa and SOMA([Sales]) > [Emerging Threshold])THEN CASE-WELL-Performing <expression>WHEN <value1>THEN <return1> <value2> <return2>... ELSE <default return=>END Performs logical tests and returns appropriate values. The CASE function evaluates the expression, compared it to a sequence of values, value1, value2, etc., and returns a result. When a value that matches the expression is found, CASE returns the corresponding return value. If no matches are found, the default return expression is used. If there is no default return and no value match, then Null is returned. CASE is often easier to use than IIF or IF THEN ELSE. Typically, you use an IF function to run an arbitrary test sequence and use a CASE function to search for a match with an expression. But a CASE function can always be rewritten as an IF function, although the CASE function will usually be more concise. You can often use a group to get the same results from a complicated case function. Examples: CASE [Region] WHEN 'West' THEN 1 WHEN 'EAST' THEN 2 FINAL CASE LEFT DA SEMANA',[Data da Ordem]),3) QUANDO 'Sun' ENT?O 0 QUANDO 'MON' ENT?O 1 QUANDO 'TER' ENT?O 2 QUANDO 'WED' ENT?O 3 QUANDO 'Qui' ENT?O 4 QUANDO 'Sex' ENT?O 5 QUANDO 'S?b' ENT?O 6 FIM SE <expr> <then>ENT?O ACABAR TESTA <else>UM</else> </then> </expr> </default> </return2> </value2> </return1> </value1> </expression> </then> </expr2> </expr1> </expr1> </expr2> </expr1> </expr2> </expr1> </False_statement> </True_statement3> </Expression3> </True_statement2> </Expression2> </True_statement1> </Expression1> </False_statement> </False_statement> of expressions returning the <then>value to the first true <expr>. Example: If [Profit] > 0 THEN 'Profitable' 'Loss' END OF OTHER ESE <expr>THEN <then>[ELSEIF &[ELSEIF<expr2> <then2>THEN...] <else>[ELSE] [ELSE] END Tests a series of expressions returning the <then>value for the first true <expr>. Example: SE [Profit] > 0 AFTER 'Profitable' ELSEIF [Profit] = 0 THEN 'Breakeven' ELSE 'Loss' END SE <expr>THEN <&then>[ELSEIF <expr2> <then2>THEN...] [ELSE <else>] END Tests a series of expressions returning the <then>value to the first true <expr>. It should be placed at the end of an expression. Example: SE [Profit] > 0 THEN 'Profitable' ELSEIF [Profit] = 0 Then 'Breakeven' ELSE 'Loss' FINAL SE <expr>THEN <then>[ELSEIF <expr2> <then2>THEN...] <else>[ELSE] [ELSE] END Tests a series of expressions returning the <then>value for the first true <expr>. Example: SE [Profit] > 0 AFTER 'Profitable' ELSEIF [Profit] = 0 Then 'Breakeven' ELSE 'Loss' END IFNULL IFNULL (expr1, expr2) Returns <expr1>if not null, otherwise returns <expr2>. Example: IFNULL ([Profit], 0) IIF IIF (test, then[unknown]) Checks whether a condition is met and returns a value if TRUE, another value if FALSE, and a third optional value or NULL, if unknown. Example: IIF ([Profit] > 0, 'Profit', 'Loss') ISDATE ISDATE (string) Returns true if a given sequence is a valid date. Example: ISDATE (2004-04-15) = True ISNULL ISNULL (expression) Returns true if the expression does not contain valid data (Null). Example: ISNULL([Profit]) MAX MAX (expression) or Max(expr1, expr2) Returns the maximum of a single expression in all records or the maximum of two expressions for each record. Example: MAX([Sales]) MIN MIN (expression) or MIN(expr1, expr2) Returns the minimum of one expression in all records or the minimum of two expressions for each record. Example: MIN([Profit]) NO IF NOT <expr>FOR THEN END Performs <then>logical negation in an expression. Example: IF NOT [Profit] > 0, THEN Unprofitable END OR IF <expr1>OR THEN FIM Performs a <expr2> <then>logical disjunction in two expressions. Example: SE [Profit] < 0= or= [profit]=0 then= needs= improvement= end= then= if=> <expre>THEN <then>[ELSEIF ,expr2> <then2>THEN...] <else>[ELSE] END Tests a series of expressions returning the <lt;then&then>value for the first true <expr>. Example: SE [Profit] > 0 AFTER 'Profitable' ELSEIF [Profit] = 0 Then 'Break even' ANOTHER ORDER 'not profitable' WHEN CASE <expr>WHEN <Value1>THEN <return1>... <else>[ELSE] END Finds the first match and returns the corresponding <value> <expr> <return>. Example: CASE [RomanNumberal] WHEN 'I' THEN 1 WHEN 'II' THEN 2 ELSE 3 END ZN (express?o) Retorna <expression>se n?o for nulo, caso contr?rio retorna zero. Exemplo: ZN([Lucro]) ZN([Lucro])</expression> </return> </expr> </value> </else> </return1> </Value1> </expr> </expr> </then> </else> </then2> </then> </expre> </then> </expr2> </expr1> </then> </expr> </expr2> </expr1> </expr> </then> </else> </then2> </expr2> </then> </expr> </expr> </then> </else> </then2> </expr2> </then> </expr> </expr> </then> </else> </then2> </expr2> </then> </expr> </expr> </then> </then>
