Comparison Functions

Comparison functions always return 0 or 1 (Uint8).

The following types can be compared:

  • numbers
  • strings and fixed strings
  • dates
  • dates with times

within each group, but not between different groups.

For example, you can’t compare a date with a string. You have to use a function to convert the string to a date, or vice versa.

Strings are compared by bytes. A shorter string is smaller than all strings that start with it and that contain at least one more character.

equals, a = b and a == b operator

notEquals, a != b and a <> b operator

less, < operator

greater, > operator

lessOrEquals, <= operator

greaterOrEquals, >= operator
