Literals

Literal	Description	Example
text	Used to create a text value. Start with either " or ' and end the literal with the same character.	Input Value: "Hello ""Customer""" Result: Hello "Customer"
integer	Used to create an integral value.	Input Value: 1 Result: 1
decimal	Used to create a real (decimal) value.	Input Value: 1.0 Result: 1.0
boolean	Used to create a Boolean value, “yes” or “true”; and “no” or “false”.	Input Value: yes Result: true
date time	Used to create a date time value. It must be one of the following: [year month day] [year month day hour:minute] [year month day hour:minute:second]	Input Value: [2001 01 01] Result: First January 2001 Input Value: [1001*2 01 01] Result: First January 2002
time span	Used to create a time span. It must be one of the following: [hours:minutes:seconds] [days:hours:minutes:seconds] [days:hours:minutes:seconds:milliseconds]	Input Value: [15:0:0] Result: 15 hours Input Value: [8*2:0:0:0] Result: 16 days

Number Literals

Numbers can either be integers or decimals; for example, 5 and 5.1. Remember even 5.0 is a decimal. Exception: When working with mathematical or comparison operators it is valid (unlike functions) to use text. For instance the following is perfectly valid:

"5" + 1

However, if the operator is not mathematical two strings will be left as strings:

"A" > "5"

However if one is a number both will be numbers:

"1" > 2

Finally, these string values are NOT validated – they will only fail at runtime. Validation in this case has been relaxed to make it simpler to use Field Parts that do not have the correct type.

String Literals

Strings are pieces of text. They can start with either a double quote " or a single quote '; they must start and end with the same type of quote. They can contain new lines. To add a quote in the middle of a string, double it up. For instance:

"Dear Customer,

We would like to thank you for the purchase of ""Product"".

Regards

Management"

Or:

'Dear Customer,

We would like to thank you for the purchase of ''Product''.

Management'

Adding a Field Part in the middle of the string can be done in the following way: "Dear " + [Customer] + ","

Boolean Literals

Valid values for Boolean literals are true and false, as well as yes and no.

Date Literals

Dates can be specified in an expression using the following syntax:

Date and time span literals can also contain operators or Field Parts in their terms, as long as they evaluate to positive integer values. For example the following expression is valid:

Subtraction:

Two dates can also be subtracted, whether Field Part or date literal. This will result in a time span.

Timespan Literals

You can also specify time differences in an expression. Please note that a TimeSpan cannot be the result of an expression because K2 does not support it outside of the expression builder – it must be used to form a date.

Timespan behave the same as date literals – you can use operators inside of terms. The following expression will result in a valid Timespan:

Addition:

You can add two time spans (results in a Timespan). You can also add a Timespan to a DateTime which results in a DateTime. Example:

Subtraction:

You can subtract two TimeSpans (results in a TimeSpan). This will give you the difference between them. Example:

Negation:

This will make the TimeSpan negative (results in a TimeSpan).
