Structs
SQL assignment foo = expr

.
A single CTE (used after WITH
): alias [(col1, col2, ...)] AS ( query )
The names in the column list before AS

A LISTAGG
invocation LISTAGG( [ DISTINCT ] <expr>[, <separator> ] [ON OVERFLOW <on_overflow>] ) ) [ WITHIN GROUP (ORDER BY <within_group1>[, ...] ) ]
A name of a table, view, custom type, etc., possibly multi-part, i.e. db.schema.obj
An ORDER BY
expression
The most complete variant of a SELECT
query expression, optionally
including WITH
, UNION
/ other set operations, and ORDER BY

, or as an operand
to a set operation like UNION
.
Specifies the data processed by a window function, e.g.
RANGE UNBOUNDED PRECEDING
or ROWS BETWEEN 5 PRECEDING AND CURRENT ROW
.
A window specification (i.e. OVER (PARTITION BY .. ORDER BY .. etc.)
)
Enums
An ALTER TABLE
(Statement::AlterTable
) operation
Binary operators

s are modifiers that follow a column definition in a CREATE TABLE

External table’s available file format
The ON OVERFLOW
clause of a LISTAGG invocation
Stores the keyword after OFFSET <number>
<referential_action> = { RESTRICT | CASCADE | SET NULL | NO ACTION | SET DEFAULT }
One item of the comma-separated list following SELECT
A node in a tree, representing a “query body” expression, roughly:
SELECT ... [ {UNION|EXCEPT|INTERSECT} SELECT ...]
Sqlite specific syntax
A top-level statement (SELECT, INSERT, CREATE, etc.)
A table-level constraint, specified in a CREATE TABLE
or an
ALTER TABLE ADD <constraint>
statement.
A table name or a parenthesized subquery with an optional alias
