Virtual column expressions
Expression language
You can use standard JavaScript-like expression language. DBeaver uses the Jexl engine to process expressions. Language reference and examples can be found here: http://commons.apache.org/proper/commons-jexl/reference/syntax.html
Column values
All columns' values in the current result set can be referred to by name.
Expression column1 + column2 will produce the sum of two numeric columns or concatenation of two string columns column and column2.
Standard functions
Standard functions declared in namespaces.
You can refer to the functions in the namespaces as variables - nsName.functionName(parameters.md).
math
You can access all math functions as math.function(parameters.md).
You can find all supported math functions here: https://docs.oracle.com/cd/E12839_01/apirefs.1111/e12048/functmath.htm
