Tableau supports string, date/datetime, number, and Boolean data types. These data types are automatically handled in the respective fashion.
The data types supported by Tableau are described below.
A sequence of zero or more characters. For example, “Alabama”, “1234”, and “Rahul” are all strings. Strings are recognized by single or double quotes.
Date represents a date value. These generally omit time. When time is also present along with date it is referred to as datetime. Eg of date : January 23, 1972 and an example of datetime would be January 23, 1972 12:32:00 AM
Numerical values in Tableau can be either integers or floating-point numbers.
A field that contains the values TRUE or FALSE. An unknown value arises when the result of a comparison is unknown. Unknown booleans are automatically converted to Null.
