This PR added starts_with, ends_with, contains functions to yaml files.

I think you meant this?

Suggested change

	- value: any1
	- value: T

[rui-mo]

The function we need is already covered by OrList expression. Removed this.

I think you're looking for the orlist expression (as opposed to introducing in).

For the character matching functions, I suggest you also include all permutations of fixed character, string and varchar combinations.

Thanks for your comment. Removed in function and added the permutations for starts_with, ends_with, contains.
