Error message

parsing error: {0}

What it means

Error::Parse wraps a ParseError from parsing InfluxQL input in iox_query_influxql_rewrite, displayed as 'parsing error: {0}'. parse_statements fails when the input string is not syntactically valid InfluxQL.

Solutions

1. Inspect the wrapped ParseError for the exact token/position
2. Fix the query syntax to valid InfluxQL
3. Validate the query with a parser/linter before sending it
4. Check the parser crate version supports the query's syntax

Example fix

// before
parse_statements("SELECT * FROM m WHERE time > now() - 1w ORDER BY time DESC LIMIT 10, 20")?;
// after
parse_statements("SELECT * FROM m WHERE time > now() - interval '1 week' ORDER BY time DESC LIMIT 20")?;

// pre-validate with the same parser
if let Err(e) = influxql_parser::parse_statements(input) { return Err(e.into()); }

match parse_statements(input) {
    Err(Error::Parse(pe)) => { show_syntax_error(&pe); return; }
    other => other?,
}

When it happens

Trigger: Calling parse_statements with malformed InfluxQL — syntax typos, unsupported keywords, or dialect constructs the parser does not accept.

Common situations: Hand-written queries with typos; copying SQL (not InfluxQL) syntax like LIMIT x,y; version differences where newer query features are unknown to the bundled parser.
