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.
