The request for PartitionQuery
Attributes
-
paramTypes
(type:%{optional(String.t) => GoogleApi.Spanner.V1.Model.Type.t}
, default:nil
) - It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of typeBYTES
and values of typeSTRING
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. -
params
(type:map()
, default:nil
) - 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. -
partitionOptions
(type:GoogleApi.Spanner.V1.Model.PartitionOptions.t
, default:nil
) - Additional options that affect how many partitions are created. -
sql
(type:String.t
, default:nil
) - 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 with a PartitionedDml transaction for large, partition-friendly DML operations. -
transaction
(type:GoogleApi.Spanner.V1.Model.TransactionSelector.t
, default:nil
) - Read only snapshot transactions are supported, read/write and single use transactions are not.
