Expand description

Table query: SELECT columns FROM table WHERE filter ORDER BY … LIMIT …

Fields§

§table: String

Table name. Legacy slot — still populated even when source is set to a subquery so existing call sites that read query.table.as_str() keep compiling. When source is Some(TableSource::Subquery(…)), this field holds a synthetic sentinel name ("__subq_NNNN") that runtime code must never resolve against the real schema registry.

§source: Option<TableSource>

Fase 2 Week 3: structured table source. None means the legacy table field is authoritative. Some(Name) is the same information as table but in typed form. Some(Subquery) wires a (SELECT …) AS alias in a FROM position — the Fase 1.7 unlock.

§alias: Option<String>

Optional table alias

§select_items: Vec<SelectItem>

Canonical SQL select list.

§columns: Vec<Projection>

Columns to select (empty = all)

§where_expr: Option<Expr>

Canonical SQL WHERE clause.

§filter: Option<Filter>

Filter condition

§group_by_exprs: Vec<Expr>

Canonical SQL GROUP BY items.

§group_by: Vec<String>

GROUP BY fields

§having_expr: Option<Expr>

Canonical SQL HAVING clause.

§having: Option<Filter>

HAVING filter (applied after grouping)

§order_by: Vec<OrderByClause>

Order by clauses

§limit: Option<u64>

Limit

§limit_param: Option<usize>

User-supplied-parameter slot for LIMIT $N. Set by the parser when the LIMIT clause references $N/? instead of a literal; cleared by the binder (user_params::bind) after substituting the parameter into limit. Mirrors the limit_param slot on SearchCommand variants — see #361 slice 11.

§offset: Option<u64>

Offset

§offset_param: Option<usize>

User-supplied-parameter slot for OFFSET $N. Same lifecycle as limit_param. See #361 slice 11.

§expand: Option<ExpandOptions>

WITH EXPAND options (graph traversal, cross-ref following)

§as_of: Option<AsOfClause>

Time-travel anchor. When present the executor resolves this to an MVCC xid and evaluates the query against that snapshot instead of the current one. Mirrors git’s AS OF semantics.

Implementations§

Source§

impl TableQuery

Source

pub fn new(table: &str) -> Self

Create a new table query

Source

pub fn from_subquery(subquery: QueryExpr, alias: Option<String>) -> Self

Create a TableQuery that wraps a subquery in FROM position. The legacy table slot holds a synthetic sentinel so code that only reads table.as_str() errors loudly with a recognisable marker instead of silently treating it as a real collection.
