honey.sql.pg-ops
Register all the PostgreSQL JSON/JSONB operators and provide convenient Clojure names for those ops. In addition, provide names for the PostgreSQL regex operators as well.
For the eleven that cannot be written directly as symbols, use mnemonic names: hash for #, at for @, and tilde for ~.
For the six of those that cannot be written as
keywords, invoke the keyword function instead.
Those latter eight (at>, <at, at?, atat,
tilde, tilde*, !tilde, and !tilde*) are
the only ones that should really be needed in the
DSL. The other names are provided for completeness.
regex and iregex are provided as aliases for the
regex operators tilde and tilde* respectively.
!regex and !iregex are provided as aliases for the
regex operators !tilde and !tilde* respectively.

For the eleven that cannot be written directly as symbols, use mnemonic names: hash for #, at for @, and tilde for ~. For the six of those that cannot be written as keywords, invoke the `keyword` function instead. Those latter eight (`at>`, `<at`, `at?`, `atat`, `tilde`, `tilde*`, `!tilde`, and `!tilde*`) are the only ones that should really be needed in the DSL. The other names are provided for completeness. `regex` and `iregex` are provided as aliases for the regex operators `tilde` and `tilde*` respectively. `!regex` and `!iregex` are provided as aliases for the regex operators `!tilde` and `!tilde*` respectively.
!tildeclj/s

-clj/s
The - operator:
- text value: deletes a key (and its value) from a JSON object, or matching string value(s) from a JSON array
- int value: deletes the array element with specified index (negative integers count from the end)
The - operator: - text value: deletes a key (and its value) from a JSON object, or matching string value(s) from a JSON array - int value: deletes the array element with specified index (negative integers count from the end)
->clj/s
The -> operator for accessing nested JSON(B) values as JSON(B). Ex.:
(sql/format {:select [[[:->> [:-> :my_column "kids" [:inline 0]] "name"]]]})
; => ["SELECT (my_column -> ? -> 0) ->> ?" "kids" "name"]
Notice we need to wrap the keys/indices with :inline if we don't want them to become parameters.

atatclj/s
The @@ operator - returns the result of a JSON path predicate check for the specified JSON value. Only the first item of the result is taken into account. If the result is not Boolean, then NULL is returned.
