Operations available on ALTER DATABASE <name> <operation>.

Every variant must be matched exhaustively — no _ => arms anywhere.

Variants

Rename

ALTER DATABASE <name> RENAME TO <new_name>

Fields

new_name: String

SetQuota(QuotaSpec)

ALTER DATABASE <name> SET QUOTA (max_memory_bytes = ..., ...)

All fields in the spec are optional; absent fields leave the existing quota value unchanged (merged at apply time with the stored record or QuotaRecord::DEFAULT).

SetDefault

ALTER DATABASE <name> SET DEFAULT — marks this database as the per-user default for future sessions. Returns FEATURE_NOT_YET_IMPLEMENTED until the per-user default-database binding lands; the canonical path is ALTER USER <name> SET DEFAULT DATABASE <db>.

Materialize

ALTER DATABASE <name> MATERIALIZE — triggers background materialization of a cloned database. Returns FEATURE_NOT_YET_IMPLEMENTED until the clone/mirror subsystem lands.

Promote

ALTER DATABASE <name> PROMOTE — promotes a mirror to writable primary. Returns FEATURE_NOT_YET_IMPLEMENTED until the mirror subsystem lands.

SetAuditDml(AuditDmlMode)

ALTER DATABASE <name> SET AUDIT_DML = <mode> — sets the DML audit level.

SetIdleTimeout(u64)

ALTER DATABASE <name> SET IDLE_TIMEOUT = <secs> — sets the idle session timeout in seconds for sessions in this database. 0 disables the per-database timeout (falls back to the global idle_timeout_secs setting).

Trait Implementations

impl Clone for AlterDatabaseOperation

fn clone(&self) -> AlterDatabaseOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterDatabaseOperation

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

Formats the value using the given formatter.

impl PartialEq for AlterDatabaseOperation

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