2/2/2024 0 Comments Golang json compare![]() SELECT * FROM items WHERE attrs->'ingredients' ? 'Salt' The ? operator can also be used to check for the existence of a specific SELECT * FROM items WHERE (attrs->'dimensions'->'weight')::numeric 'dimensions' ? 'weight' SELECT * FROM items WHERE attrs->'name' ILIKE 'p%' You can use the returned values as normal, although you may need to type Or you can use -> to do the same thing, but this returns a TEXT value SELECT attrs->'dimensions'->'weight' FROM items The -> operator is used to get the value for a key. Create an index on a specific key/value pair in the JSONB column.ĬREATE INDEX idx_items_attrs_organic ON items USING gin ((attrs->'organic')) Create an index on all key/value pairs in the JSONB column.ĬREATE INDEX idx_items_attrs ON items USING gin (attrs) lowercase `true` and `false` spellings are accepted. You can insert any well-formed json input into the column. Here's a cribsheet for the essential commands: The PostgreSQL documentation recommends that you should generally use JSONB, unless you have a specific reason not too (like needing to preserve key order). JSONB also supports the ? (existence) and (containment) operators, whereas JSON doesn't. It may change the key order, and will remove whitespace and delete duplicate keys. This makes it slower to insert but faster to query. JSONB stores a binary representation of the JSON input.JSON stores an exact copy of the JSON input.vjson - Go package for validating JSON objects with declaring a JSON schema with fluent API.PostgreSQL provides two JSON-related data types that you can use - JSON and JSONB.ujson - Fast and minimal JSON parser and transformer that works on unstructured JSON.omg.jsonparser - Simple JSON parser with validation by condition via golang struct fields tags.OjG - Optimized JSON for Go is a high performance parser with a variety of additional JSON tools including JSONPath.It currently takes stdin and outputs JSON. marshmallow - Performant JSON unmarshaling for flexible use cases.mapslice-json - Go MapSlice for ordered marshal/ unmarshal of maps in JSON.kazaam - API for arbitrary transformation of JSON documents.jzon - JSON library with standard compatible API/behavior.jsonic - Utilities to handle and query JSON without defining structs in a type safe manner.jsonhandlers - JSON library to expose simple handlers that lets you easily read and write json from various sources.jsonhal - Simple Go package to make custom structs marshal into HAL compatible JSON responses.jsongo - Fluent API to make it easier to create Json objects.jsonf - Console tool for highlighted formatting and struct query fetching JSON.jsondiff - JSON diff library for Go based on RFC6902 (JSON Patch).jsoncolor - Drop-in replacement for encoding/json that outputs colorized JSON.jsonapi-errors - Go bindings based on the JSON API errors reference.Provides package that can parse multiple JSON documents and create struct to fit them all. json2go - Advanced JSON to Go struct conversion.JSON-to-Proto - Convert JSON to Protobuf online.JSON-to-Go - Convert JSON to Go struct.jscan - High performance zero-allocation JSON iterator.jettison - Fast and flexible JSON encoder for Go.JayDiff - JSON diff utility written in Go.htmljson - Rich rendering of JSON as HTML in Go.gojson - Automatically generate Go (golang) struct definitions from example JSON.gojmapr - Get simple struct from complex json by json path.go-respond - Go package for handling common HTTP JSON responses.go-jsonerror - Go-JsonError is meant to allow us to easily create json response errors that follow the JsonApi spec.GJSON - Get a JSON value with one line of code.gjo - Small utility to create JSON objects.No custom structs, no code generation, no reflection. fastjson - Fast JSON parser and validator for Go.epoch - Contains primitives for marshaling/unmarshaling Unix timestamp/epoch to/from build-in time.Time type in JSON.ej - Write and read JSON from different sources succinctly.dynjson - Client-customizable JSON formats for dynamic APIs.Works in combination with encoding/json and other packages that "Unmarshal" arbitrary data into Go data-types. ask - Easy access to nested values in maps and slices.ajson - Abstract JSON for golang with JSONPath support.
