![]() IF DATETRUNC('month', ) = DATETRUNC('month', ) Create a calculated field with a name like "Orders Shipped" with a calculation similar to the following:.In the Edit Alias dialog, type in a new name and click OK.Right-click the header "Distinct count of Order ID" in the view and select Edit Alias….In the Drop Field dialog, select CNTD(Order ID).Right-click and drag to Text on the Marks card.In the Drop Field dialog, select MY(Order Date) with the blue # icon and click OK.Right-click and drag to the Rows shelf. ![]() Choose one date field to create the date axis or headers.In this example, every row is a month, therefore both and need to have at least one order for every month. New Values: The name give the new column that contains the original values from Pivot Column Values 1-3.This option requires that every date field have at least one record for every date bin in the view. New Column Header: The name you give the new column that contains the new row values from New Value (from Column Header 1-3). Pivot Column Values 1-3: The columns whose values need to be pivoted into a single column. New Value (from Column Header 1-3): New names that you give to the original column headers, which are used as row values in the pivot. Static Column: A comma-delimited list of the columns from Table, both dimensions and measures, which should not be included in the pivot. In the Edit Custom SQL dialog box, copy and paste the following custom SQL query and replace the contents with information about your table: Select, ' New Value (from Column Header 1)' as, as From Union ALL Select, ' New Value (from Column Header 2' as, as From Union ALL Select, ' New Value (from Column Header 3' as, as From For more information, see Connect to a Custom SQL Query. Runnerĭouble-click the New Custom SQL option in the left pane. The following table shows the results of this custom SQL query. Pivots the Start Time and End Time columns so that their values are in a new column called Time.Pivots the End Time column header into a string value called End and adds that value to a new column called Action.Pivots the Start Time column header into a string value called Start and adds that value to a new column called Action.The above custom SQL query does the following: Select, 'Start' as, as From Union ALL Select, 'End' as, as From To optimize your analysis of this data in Tableau, you can use the following custom SQL query to pivot the "Start Time" and "End Time" columns so that their values are in a single column. When you use the UNION ALL operator in a custom SQL query, you can take values from distinct columns and put them into a new column.įor example, suppose you have a table called Contest. You can also use custom SQL to pivot your data, even if you aren't working Excel, text file, Google Sheets, and. If using a different data source in Tableau Desktop, you can use custom SQL to pivot. No pivot option: Pivot appears when you select two or more columns in a single Microsoft Excel, text file, Google Sheets, and. Null values in the grid: If all of the original fields used in the pivot are removed, for example in an extract refresh, null values display in the pivot fields. ![]() They cause fields to become red in the view or show a red exclamation point next to the field in the Data pane. Red fields in the view and fields with exclamation points in the Data pane: Because the original fields are replaced with new pivot fields, any references to the original fields in the view will no longer work. ![]() To remove a pivot, click the drop-down arrow next to the name of a pivot column, and then select Remove Pivot. Make sure that the pivot columns and values look as expected before you begin your analysis. To add more data to the pivot, select another column, click the drop-down arrow next to the column name, and then select Add Data to Pivot. The new columns replace the original columns that you selected to create the pivot. New columns called "Pivot field names" and "Pivot field values" are created and added to the data source. Click the drop-down arrow next to the column name, and then select Pivot. You can pivot your data so that the vendor is in one field and the number of devices sold is in another field.Īfter you have set up the data source, in the grid, select two or more columns. If you are working with other data sources, you can Pivot using custom SQL (Tableau Desktop).įor example, suppose you have the number of devices sold by quarter for three vendors in three separate fields. pdf data sources, you can pivot your data from crosstab format into columnar format. When working with Microsoft Excel, text file, Google Sheets, and. Sometimes, analyzing data that is stored in a crosstab format can be difficult in Tableau.
