See the documentation for more.

Responses

Responses may not match the input.

cql2-text differences

All identifiers in output are double quoted
The position of "NOT" keywords is standardized to be before the expression (ie "... NOT LIKE ..." will become "NOT ... LIKE ..."
The negative operator on anything besides a literal number becomes "* -1"
Parentheses are added around all expressions
