Available Mapping Functions

Odysseus provides a wide range of functions and operators to be used for data transformation and filtering in

...

Mathematic Function

Abs

Returns the absolute value of a value

Ceil

Floor

Round

Datatype Functions

DoubleToShort

Converts the given double value to a short value

DoubleToByte

Converts the given double value to a byte value

DoubleToFloat

Converts the given double value to a float value

DoubleToLong

Converts the given double value to a long value

ToShort

Converts the given value to a short value. This function converts any value to a short value, thus it is more time consuming than the DoubleToShort function for double values.

ToByte

Converts the given value to a byte value. This function converts any value to a byte value, thus it is more time consuming than the DoubleToByte function for double values.

ToFloat

Converts the given value to a float value. This function converts any value to a float value, thus it is more time consuming than the DoubleToFloat function for double values.

ToLong

Converts the given value to a long value. This function converts any value to a long value, thus it is more time consuming than the DoubleToLong function for double values.

 

your query statements. In Odysseus-Studio there is a view MEP Functions View, that lists all current available operators and functions.

Attentation: For most numeric operators the result is a floating value. This will be fixed in future versions.

Basic Operators

Mathematical Operators; +,-,/,*, % (modulo), ^ (power)

Logical Operators: && (and), || (or), !(not), xor

Compare Operators: !=, = or ==, <=, >=

Functions and operators in CQL

If you prefer CQL you can use these functions and operators in your Select clause for data transformation or in the Where clause for filtering:

Code Block
languagesql
titleExample
SELECT tan(x) FROM stream WHERE sqrt(y)>3

Functions and operators in PQL

If you prefer PQL you can use these functions and operators in the MAP, JOIN, and SELECT operator. In addition, functions and operators can be used in other operators that are not part of the set of relational operators.

Code Block
languagejs
titleExample
output = MAP({expressions = ['tan(x)']}, SELECT({predicate = RelationalPredicate('sqrt(y)>3')}, stream))


Some of the functions and operators are part of the Odysseus Core and some are available in additional features. On the following child pages you find all currently available functions and operators with their description and examples.
