Operators and Precedence

ProcessMind expressions support a variety of operators for arithmetic calculations, comparisons, and logical operations.

Operator Notes

• String concatenation with +: the + operator also concatenates strings when either operand is a string:

  "Hello" + " " + "World"  →  "Hello World"

• The in operator is equivalent to multiple OR comparisons:

  Status in ["Pending", "Active", "Review"]
  // is the same as:
  Status == "Pending" || Status == "Active" || Status == "Review"

Examples

• Combining conditions:

  // Both conditions must be true
  Amount > 1000 && Region == "Europe"
  
  // At least one condition must be true  
  Priority == "High" or Escalated == true
  
  // Negation
  not IsArchived

Ternary Operator

The ternary operator provides a shorthand for simple if/else logic:

• Syntax:

  condition ? valueIfTrue : valueIfFalse

• Example:

  Amount > 1000 ? "High" : "Low"

• Equivalent to:

  if(Amount > 1000, "High", "Low")

Precedence Examples

• Without parentheses:

  2 + 3 * 4     →  14  (multiplication first)
  10 > 5 && 3 < 7  →  true  (comparisons before AND)

• With parentheses:

  (2 + 3) * 4   →  20  (addition first)

Special Syntax

• Quoted Identifiers: If a column name contains spaces or special characters, use backticks:

  `Order Amount` * 0.1
  `Customer Name`
  `2024 Revenue`

• String Escaping: Use backslash to escape special characters in strings:

  "Line 1\nLine 2"     // newline
  "Tab\there"          // tab
  "Say \"Hello\""      // double quote
  "Path\\to\\file"     // backslash

• Null Values: null represents a missing value, and any comparison involving null returns null rather than true or false. Test for a missing value with the isNull() function:

  if(isNull(Department), "Unknown", Department)
