[−][src]Struct gcp_client::google::spanner::v1::execute_sql_request::QueryOptions
Query optimizer configuration.
Fields
optimizer_version: String
An option to control the selection of optimizer version.
This parameter allows individual queries to pick different query optimizer versions.
Specifying "latest" as a value instructs Cloud Spanner to use the
latest supported query optimizer version. If not specified, Cloud Spanner
uses optimizer version set at the database level options. Any other
positive integer (from the list of supported optimizer versions)
overrides the default optimizer version for query execution.
The list of supported optimizer versions can be queried from
SPANNER_SYS.SUPPORTED_OPTIMIZER_VERSIONS. Executing a SQL statement
with an invalid optimizer version will fail with a syntax error
(INVALID_ARGUMENT
) status.
The optimizer_version
statement hint has precedence over this setting.
