Change the data type of your field in Tableau from date-time to date. You can do that by right clicking on the field in the data pane. That doesn't change your source data - Tableau never does that as it is a read-only viewer - Changing the data type simply changes how Tableau views the data. An alternate shortcut is to click on the data.
The DATEPART () function allows us to return a specific piece of a date time field. Because the DATEPART () function returns either the number of hours or the number of minutes as a standalone number, we have to write a condition that will specify both hour and minute. To view the above steps in action, see the video below The Data Update Time value depends on the type of connection: Extract-based connections display the last time the extract was refreshed. Live file-based and live database connections display the last time the data source was refreshed in Tableau. When using data blending, the timestamp reflects the update time of the primary data source
Finding the date difference in the tableau is easy but the same is not with the time difference in Tableau. In this post, we will see how to calculate the time difference in Tableau using examples.

DATE (LEFT ([Original Date],2) + / MID ([Original Date],3) + / + RIGHT ([Original Date],4) This function essentially works in the reverse of DATENAME by converting a string into a date/time with your specified format. If the string does not match the date/time format, then it will return a value of Null. Example: This function is only available for Microsoft Excel, MySQL, Oracle, PostgreSQL, Tableau data extract and text file data.

You can change the data type in the data pane to just be date or you can wrap the calculation above with the DATE() function, which hard codes the new field as the date data type As a reference, extract from Tableau own knowledge base:. To convert the field to UTC time, use the following calculation: DATEADD('second', [Unix time field], #1970-01-01#
.com data source, Tableau retrieves all objects and the extract creation can be time consuming - several hours in some cases. Allow the initial extract to complete and use incremental refreshes to keep the data up-to-date. In summary, be sure to keep in mind these simple best practices When you have a Date or DateTime field type in Tableau, you can easily convert this into the number form using either INT([Date]) or FLOAT([DateTime]). Luckily the reverse is also true, e.g. the expression: DATETIME(43590) will return 07/05/2019 00:00:00.

Method 1: Setting up Tableau Extract Manually. Let's talk about what an Extract is.

Depending on the version you are using, you can extract data from Tableau in different storage formats . After we get the correct number we must divide by 1000 (1000 milliseconds in a second) and 60 (60 seconds in a minute). The last step is to convert the remaining number into a number using the INT function. The calculation for Seconds is similar Note: The data engine, which is the underlying mechanism that Tableau uses to create extracts, stores time values with a precision of up to 3 decimal places. If you specify a datetime or timestamp column for Identify new rows using column, and your database uses a higher precision than Tableau, you can end up with duplicate rows after an incremental refresh

If you get billed for the amount of data you request from the database, or have a complex SQL statement with a lot of calculations that takes a long time to run, or a relatively small amount of memory or disk space on. That will create a new column with the file name. You can then parse out the date. If the name will always be in the format you describe, then I would simply do a formula tool where the formula is Right([filename],8), call it date_out_0, and then feed that into a DateTime tool using the custom input as dd.mm.yy We'll use this to create a list of all dates we wish to use in our scaffold.
