2004#
< (Less than) Compares two numbers or
two strings or two dates
[Profit] < 20000
[Category] < ‘Q’

![Logical Operators
Operator Description Example
AND If the expressions or
Boolean values present on
both
[Ship Date] > #April
1, 2012# AND
[Profit] > 10000
OR If any one or both of the
expressions or Boolean
values present
[Ship Date] > #April
1, 2012# OR
[Profit] > 10000
NOT This operator negates the
Boolean value of the
expression present after it.
NOT [Ship Date] >

![Number Functions
• Function Description Example
• CEILING (number)
• Rounds a number to the nearest integer of equal or
greater value.
• CEILING(2.145) = 3
• POWER (number,power)
• Raises the number to the specified power.
• POWER(5,3) = 125
• ROUND (number,[decimals])
• Rounds the numbers to a specified number of digits.
• ROUND(3.14152,2) =3.14](https://image.slidesharecdn.com/tableauppt-230514175154-6d32d2ec/85/Tableau-PPT-ppt-66-320.jpg)

- 61. General Operators Operator Description Example +(addition) Adds two numbers. Concatenates two strings. Adds days to dates. 7 + 3 Profit + Sales 'abc' + 'def' = 'abcdef' #April 15, 2004# + 15 = #April 30, 2004# – (subtraction) Subtracts two numbers. Subtracts days from dates. -(7+3) = -10 #April 16, 2004# - 15 = #April 1,2004#
- 62. Arithmetic Operators Operator Description Example *(Multiplication) Numeric multiplication 23*2 = 46 /(Division) Numeric division 45/2 = 22.5 %(modulo) Reminder of numeric division 13 % 2 = 1 ^(power) Raised to the power 2^3 = 8
- 63.

- 81. Tableau ─ LOD Expressions • Level of Detail (LOD) expressions are used to run complex queries involving many • dimensions at the data source level instead of bringing all the data to Tableau interface. A • simple example is adding dimension to an already calculated aggregate value. • Types of LOD • There are three main types of LOD expressions. • FIXED LOD: This expression computes values using the specified dimensions • without reference to any other dimensions in the view. • INCLUDE LOD: This level of detail expressions compute values using the specified • dimensions in addition to whatever dimensions are in the view. • EXCLUDE LOD: These levels of detail expressions subtract dimensions from the • view level of detail.
