Typed sub-operation for ALTER COLLECTION <name> ....

Each variant corresponds to one ALTER sub-command parsed by nodedb-sql/src/ddl_ast/parse/collection.rs. The handler in nodedb/src/control/server/pgwire/ddl/collection/alter/ matches on this enum instead of rescanning raw SQL.

Variants

AddColumn

ADD [COLUMN] <name> <type> [NOT NULL] [DEFAULT expr]

Fields

column_name: String

column_type: String

not_null: bool

default_expr: Option<String>

DropColumn

DROP COLUMN <name>

Fields

column_name: String

RenameColumn

RENAME COLUMN <old> TO <new>

Fields

old_name: String

new_name: String

AlterColumnType

ALTER COLUMN <name> TYPE <type>

Fields

column_name: String

new_type: String

OwnerTo

OWNER TO <user>

Fields

new_owner: String

SetRetention

SET RETENTION = '<duration>'

Fields

value: String

SetAppendOnly

SET APPEND_ONLY

SetLastValueCache

SET LAST_VALUE_CACHE = TRUE|FALSE

Fields

enabled: bool

SetLegalHold

SET LEGAL_HOLD = TRUE|FALSE TAG '<tag>'

Fields

enabled: bool

tag: String

AddMaterializedSum

ADD [COLUMN] <target_column> ... AS MATERIALIZED_SUM SOURCE <source_collection> ON <join_column> VALUE <value_expr> — fully parsed by nodedb-sql; the handler receives typed fields and never rescans raw SQL.

Fields

target_collection: String

Target collection name (lowercased).

target_column: String

Target column name to hold the sum (lowercased).

source_collection: String

Source collection name (lowercased).

join_column: String

Join column on the source side (lowercased).

value_expr: String

Value expression (column name or qualified source.column, lowercased).

SetOnConflict

SET ON CONFLICT <policy_keyword> FOR <constraint_kind_keyword>

Sets the per-collection, per-constraint-kind conflict resolution policy.

Fields

policy: ConflictPolicyKind

Parsed conflict policy keyword.

constraint_kind: ConstraintKindKeyword

Which constraint kind this policy applies to.

Trait Implementations

impl Clone for AlterCollectionOp

fn clone(&self) -> AlterCollectionOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterCollectionOp

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

Formats the value using the given formatter.

impl PartialEq for AlterCollectionOp

fn eq(&self, other: &AlterCollectionOp) -> 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.
