function json_array_length(varchar) returns bigint
🔗 Official Documentation
Evaluates the JSONPath-like expression json_path on json (a string containing JSON) and returns the result as a JSON string.
Supported Signatures
function json_extract(json, jsonpath) returns json
function json_extract(varchar, jsonpath) returns json
🔗 Official Documentation
Like json_extract(), but returns the result value as a string (as opposed to being encoded as JSON). The value referenced by json_path must be a scalar (boolean, number or string).
Supported Signatures
function json_extract_scalar(json, jsonpath) returns varchar
function json_extract_scalar(varchar, jsonpath) returns varchar
🔗 Official Documentation
Returns the JSON text serialized from the input JSON value. This is inverse function to json_parse().
Supported Signatures
function json_format(json) returns varchar
🔗 Official Documentation
json_parse
Returns the JSON value deserialized from the input JSON text. This is inverse function to json_format().
Supported Signatures
function json_parse(varchar) returns json
🔗 Official Documentation
json_size
Like json_extract(), but returns the size of the value. For objects or arrays, the size is the number of members, and the size of a scalar value is zero.
Supported Signatures
function json_size(json, jsonpath) returns bigint
function json_size(varchar, jsonpath) returns bigint
