issue #23935
What this PR does / why we need it:
The
->JSON extract operator followed by comparison (>,<,>=,<=) was silently casting JSON to VARCHAR and performing string comparison, which deviates from MySQL behavior. MySQL returns an error for JSON-to-string ordering comparisons.Changes:
jsonOrderingWithStringNotSupportedhelper infunc_compare.goand applied it inlist_operator.goto restore the JSON+string ordering error for>,<,>=,<=andBETWEEN.=comparison on JSON-extracted strings to use unquoted values ('CODE-3'instead of'"CODE-3"'), matching MySQL semantics.MarshalJSONerrors injsonToStrinstead of silently ignoring them.func_json_extract.test,func_like.test, androw_constructor.sqlto reflect the corrected behavior.
