hi.
seems there is no explanation about, json_api_common_syntax in
functions-json.html
I can get json_query full synopsis from functions-json.html as follows:
json_query ( context_item, path_expression [ PASSING { value AS
varname } [, ...]] [ RETURNING data_type [ FORMAT JSON [ ENCODING UTF8
] ] ] [ { WITHOUT | WITH { CONDITIONAL | [UNCONDITIONAL] } } [ ARRAY ]
WRAPPER ] [ { KEEP | OMIT } QUOTES [ ON SCALAR STRING ] ] [ { ERROR |
NULL | EMPTY { [ ARRAY ] | OBJECT } | DEFAULT expression } ON EMPTY ]
[ { ERROR | NULL | EMPTY { [ ARRAY ] | OBJECT } | DEFAULT expression }
ON ERROR ])
seems doesn't have a full synopsis for json_table? only partial one
by one explanation.
