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
