What are Formulas?

Tabula's formula language has a lot to offer, with hundreds of functions quite similar to your favorite ones in Excel and SQL. Formulas can be as simple as a single number or as complex as a function call or mathematical formula.

Operators

• Regular math operators: +, -, *,/,%

• Comparison operators (evaluate to booleans): >, >=, <, <=, ==, !=, <>. These are used to compare two values and produce a boolean result (true or false).

• Logical operators: ! , && , || (also support not, and, or variation). These operators are used to manipulate boolean values.

• String concatenation operators: | . This is used to combine two or more strings into one.

Expressions

• Literal: represents a fixed value, like a number, "string", boolean (true, false), or a reference.

• Unary: composed of a single operand and an operator. The operator can precede the operand -expression, !expression

• Binary: consists of two operands and an operator expression operator expression.

• Grouping: expressions can be grouped using parentheses (expression) to control the precedence of evaluation.

References

References in expressions can be made to:

• Column by name: this allows for operations on specific columns in a data table.

• REGEX Path to values in the specified columns: this allows for complex data manipulation using regular expressions.

• Constants and enums: these can be used as parameters in functions.
