Also, if you wish to add a date value in the form of string characters, add a # sign before it (for instance, #22 January 2020). The time data values can be decade, year, quarter, month, day, hour, minutes, seconds, etc. Some fields can only contain a date value or a date can exist along with the time (like a timestamp). In Tableau, all formats of date and time are accepted such as dd-mm-yy, dd-mm-yyyy or mm-dd-yyyy, etc. A function known as Round function is used for rounding up float values. However, float values can also be used easily in calculations after rounding them up to corresponding integers. Most fields having numeric data type are of integer type because with float values, users face difficulty in accumulating the decimal point after a certain limit. The numeric data type values can be either an integer type or floating type. This string type can also have alphanumeric data values. You can enter as many characters as you want without having any memory allocation restrictions. Varchar string type: Varchar string type stands for variable character length where the length of the characters to be entered in a string is not fixed or predefined.This data type generally stores alphanumeric data values. If you try to enter a string value with a length greater than the fixed length, then the system is going to show an error.
Memory corresponding to this fixed length is allocated to char string type values in Tableau.

There are primarily seven data types used in Tableau. Tableau also has a set of data types based on which it characterizes every data value present in it as field values either from a live data connection or as a data extract from the data source. In a similar way, every data value will fall under a certain category of the data type.
or 03:25:40) then the data type date/time is assigned to it. If a data value is in the form of a date or time (eg. 5550) and so their data type is an integer. While some data values have whole numbers (eg. “DataFlair”) so their data type will be a string as it only contains characters. What are Data Types and Icons?ĭata types characterize the data values into its definite type. We have separate tutorials for all of it but in this tutorial, we will be learning in detail about the different data types used in Tableau.
