The following examples demonstrate how to use the MIN function.

Compares whether two expressions are equal (or not equal). The function is NULL-safe, meaning it treats NULLs as known values for comparing equality. Note that this is different from the EQUAL comparison operator ( = ), which treats NULLs as unknown values. See also:Please note that the null value is a string instead of a json native null value like: ["Simon", "Sarah", null] This can cause problems in downstream systems working with that array, because the semantics of a string and of an actual null are very different. Since we rely on the existing of "real" null values we had to come up with another solution.
