The request for PartitionQuery
Attributes
- paramTypes (%{optional(String.t) => Type}): It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type `BYTES` and values of type `STRING` both appear in params as JSON strings. In these cases, `param_types` can be used to specify the exact SQL type for some or all of the SQL query parameters. See the definition of Type for more information about SQL types. Defaults to:
null
. - params (%{optional(String.t) => String.t}): The SQL query string can contain parameter placeholders. A parameter placeholder consists of `'@'` followed by the parameter name. Parameter names consist of any combination of 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 an SQL query with unbound parameters. Parameter values are specified using `params`, which is a JSON object whose keys are parameter names, and whose values are the corresponding parameter values. Defaults to:
null
. - partitionOptions (PartitionOptions): Additional options that affect how many partitions are created. Defaults to:
null
. - sql (String.t): 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 with a PartitionedDml transaction for large, partition-friendly DML operations. Defaults to:
null
. - transaction (TransactionSelector): Read only snapshot transactions are supported, read/write and single use transactions are not. Defaults to:
null
.
