Struct SelectStatement 

pub struct SelectStatement {

    pub vector_index: Option<Box<SqlVectorIndexSearch>>,
    pub projection: Vec<SelectProjection>,
    pub distinct: bool,
    pub from: Option<SqlTableName>,
    pub from_alias: Option<String>,
    pub joins: Vec<SqlJoin>,
    pub selection: Option<SqlPredicate>,
    pub group_by: Vec<SqlColumnRef>,
    pub having: Option<SqlPredicate>,

    pub lock_strength: Option<SqlLockStrength>,
}

Fields

vector_index: Option<Box<SqlVectorIndexSearch>>

projection: Vec<SelectProjection>

distinct: bool

from: Option<SqlTableName>

None for a FROM-less SELECT (e.g. SELECT version();): the projection is evaluated exactly once against an implicit row with no column bindings, so any column reference in it is rejected the same way an unresolvable column against a real table would be.

from_alias: Option<String>

joins: Vec<SqlJoin>

selection: Option<SqlPredicate>

group_by: Vec<SqlColumnRef>

having: Option<SqlPredicate>

order_by: Vec<SqlOrderItem>

limit: Option<SqlBound>

offset: Option<SqlBound>

lock_strength: Option<SqlLockStrength>

Implementations

impl SelectStatement

pub fn from_table(&self) -> &SqlTableName

The base table, for every code path that only ever runs on a real table (catalog resolution, access-path selection, join planning, row scanning). FROM-less selects never reach these paths — they’re handled by a separate, earlier branch — so None here is a caller bug, not a user-facing state.
