Function

  compare — return an integer comparing two values

Synopsis

compare(a: any, b: any) -> int64

Description

The compare function returns an integer comparing two values. The result will be 0 if a is equal to b, +1 if a is greater than b, and -1 if a is less than b. compare differs from <, >, <=, >=, ==, and != in that it will work for any type (e.g., compare(1, "1")). null values compare greater than non-null values.

Examples

echo '{a: 2, b: "1"}' | zq -z 'yield compare(a, b)' -
