Expand description

Structural information extracted from a parsed SQL statement.

Fields§

§statement_type: SqlStatementType

High-level statement category.

§verb: String

Raw uppercase verb (“SELECT”, “INSERT”, “CREATE TABLE”, etc.) — used for explanations. For Cedar entity building use Self::statement_type.

§tables: HashSet<String>

All tables referenced by name (final path segment if qualified).

§columns: HashSet<String>

All columns referenced (where determinable). * recorded for wildcards.

§has_where: bool

Whether the statement has a WHERE clause.

§has_limit: bool

Whether the statement has a LIMIT clause.

§has_order_by: bool

Whether the statement has an ORDER BY clause.

§has_aggregation: bool

Whether the statement includes GROUP BY or aggregate functions.

§join_count: u32

Number of JOIN clauses across all FROM items.

§subquery_count: u32

Number of subqueries (naive count of nested SELECTs).

§estimated_rows: u64

Row-count estimate: LIMIT n when present, otherwise a configurable default.

§sql_length: usize

Raw length of the SQL string (characters).
