The request for [PartitionQuery][google.spanner.v1.Spanner.PartitionQuery]
- session
Required. The session used to create the partitions.
- transaction
Read only snapshot transactions are supported, read/write and single use transactions are not.
- sql
Required. The query request to generate partitions for. The request will fail if the query is not root partitionable. The query plan of a root partitionable query has a single distributed union operator. A distributed union operator conceptually divides one or more tables into multiple splits, remotely evaluates a subquery independently on each split, and then unions all results. This must not contain DML commands, such as INSERT, UPDATE, or DELETE. Use [ExecuteStreamingSql][google.spanner.v1.Spanner.ExecuteStreamingSql] with a PartitionedDml transaction for large, partition-friendly DML operations.
- params
Parameter names and values that bind to placeholders in the SQL string. A parameter placeholder consists of the
@character followed by the parameter name (for example,@firstName). Parameter names can contain letters, numbers, and underscores. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example:"WHERE id > @msg_id AND id < @msg_id + 100"It is an error to execute a SQL statement with unbound parameters.- paramTypes
It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type
BYTESand values of typeSTRINGboth appear in [params][google.spanner.v1.PartitionQueryRequest.params] as JSON strings. In these cases,param_typescan be used to specify the exact SQL type for some or all of the SQL query parameters. See the definition of [Type][google.spanner.v1.Type] for more information about SQL types.- partitionOptions
Additional options that affect how many partitions are created.
