Groovy's native ternary operator (condition ? valueIfTrue : valueIfFalse) works seamlessly in Deephaven query strings, providing a concise way to implement conditional logic.
Ternary operators can be nested for more complex conditional logic:
When using custom methods as conditions, cast the result to (Boolean):
woods = newTable(
stringCol("Type", "Pine", "Fir", "Cedar", "Oak", "Ash", "Walnut", "Beech", "Cherry"),
doubleCol("Price", 1.95, 2.50, 3.25, 3.45, 4.25, 7.95, 4.10, 5.25)
)
result = woods.update("Budget = (Price <= 3.50) ? `yes` : `no`")
woods = newTable(
stringCol("Type", "Pine", "Fir", "Cedar", "Oak", "Ash", "Walnut", "Beech", "Cherry"),
stringCol("Hardness", "soft", "soft", "soft", "hard", "hard", "hard", "hard", "hard"),
doubleCol("Price", 1.95, 2.50, 3.25, 3.45, 4.25, 7.95, 4.10, 5.25)
)
result = woods.update("Category = (Hardness == `hard`) ? ((Price <= 3.50) ? `budget` : `expensive`) : `softwood`")
budget = { price -> price <= 3.50 }
woods = newTable(
stringCol("Type", "Pine", "Fir", "Cedar", "Oak", "Ash", "Walnut", "Beech", "Cherry"),
doubleCol("Price", 1.95, 2.50, 3.25, 3.45, 4.25, 7.95, 4.10, 5.25)
)
result = woods.update("Budget = (Boolean)budget(Price) ? `yes` : `no`")
