A SELECT statement.

Fields

distinct: DistinctMode

DISTINCT mode (EPIC-052 US-001).

columns: SelectColumns

Columns to select.

from: String

Collection name (FROM clause).

from_alias: Vec<String>

Aliases visible in scope: FROM alias + JOIN aliases (BUG-8 fix).

joins: Vec<JoinClause>

JOIN clauses (EPIC-031 US-004).

where_clause: Option<Condition>

WHERE conditions.

order_by: Option<Vec<SelectOrderBy>>

ORDER BY clause.

limit: Option<u64>

LIMIT value.

offset: Option<u64>

OFFSET value.

with_clause: Option<WithClause>

WITH clause.

group_by: Option<GroupByClause>

GROUP BY clause.

having: Option<HavingClause>

HAVING clause.

fusion_clause: Option<FusionClause>

USING FUSION clause (EPIC-040 US-005).

Implementations

impl SelectStatement

pub fn outer_table_scope(&self) -> Vec<&str>

Returns the table names and aliases visible as outer scope for a nested subquery: the FROM collection plus any FROM/JOIN aliases.

A subquery’s inner WHERE is only correlated when it references one of these names; a dotted payload path whose prefix is not in this set is a plain payload filter, not a correlation (EPIC-039).

pub fn empty() -> Self

Returns an empty SelectStatement with all fields at their defaults.

Used by crate::velesql::Query::new_dml, crate::velesql::Query::new_train, and crate::velesql::Query::new_match to avoid repeating the 14-field struct literal.

pub fn is_aggregation_query(&self) -> bool

Returns true when this SELECT must run through the aggregation engine (scalar aggregates or GROUP BY) rather than the row-projection path.

NEAR ... GROUP BY (vector-search grouping) is post-processed inside the standard execute path, not the aggregate engine, so it returns false. Single source of truth shared by the server /query handler and the CLI REPL so every surface routes aggregation identically.

Trait Implementations

impl Clone for SelectStatement

fn clone(&self) -> SelectStatement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SelectStatement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectStatement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SelectStatement

fn eq(&self, other: &SelectStatement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SelectStatement

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
