Comparison Functions

This section describes the following comparison functions.

•

now

ge(<number>|<string>|<date>, <number>|<string>|<date>)

ge returns true if the first value is greater than or equal to second value. Values must both be the same type. ge may appear when defining datasource fields or in validations.

Examples:

ge(2, 2) # true

ge("hello", "world") # false, hello is lexicographically before world

ge(now, to_d("2015-11-10T11:10:06Z")) # true, current time is greater than supplied value

gt(<number>|<string>|<date>, <number>|<string>|<date>)

gt returns true if the first value is greater than second value. Values must both be same type. gt may appear when defining datasource fields or in validations.

Examples:

gt(3, 2) # true

gt("hello", "world") # false, hello is lexicographically before world

gt(now, to_d("2015-11-10T11:10:06Z")) # true, that date is in the past

le(<number>|<string>|<date>, <number>|<string>|<date>)

le returns true if value1 is less than or equal to value2. Values must both be same type. le may appear when defining datasource fields or in validations.

Examples:

le(2, 2) # true

le("hello", "world") # true, hello is lexicographically before world

le(to_d("2015-11-10T11:10:06Z"), now) # true, that date is in the past

lt(<number>|<string>|<date>, <number>|<string>|<date>)

lt returns true if value1 is less than value2. Values must both be same type. lt may appear when defining datasource fields or in validations.

Examples:

lt(2, 3) # true

lt("hello", "world") # true, hello is lexicographically before world

lt(to_d("2015-11-10T11:10:06Z"), now) # true, that date is in the past

ne(<number>|<string>|<date>, <number>|<string>|<date>)

ne returns true if first value is not equal to second value. Values must both be same type. ne may appear when defining datasource fields or in validations.

Examples:

ne(2, 3) # true

ne("hello", "world") # true

eq(<number>|<string>|<date>, <number>|<string>|<date>)

eq returns true if first value is equal to second value. Values must both be same type. eq may appear when defining datasource fields or in validations.

Examples:

eq(2, 2) # true

eq(2, "2") # false, different types

eq("hello", "hello") # true

eq("hello", "HELLO") # false

now

now()

now returns the current time in UTC timezone. It accepts no parameters.

Example:

gt(now, to_d("2015-11-10T11:10:06Z")) # true, that date is in the past
