Instance Attribute Details

#param_types ⇒ Hash<String,Google::Apis::SpannerV1::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. Corresponds to the JSON property paramTypes

Returns:

def param_types
  @param_types
end

#params ⇒ Hash<String,Object>

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. Corresponds to the JSON property params

Returns:

  • (Hash<String,Object>)

#partition_options ⇒ Google::Apis::SpannerV1::PartitionOptions

def partition_options
  @partition_options
end

#sql ⇒ String

Required. The query request to generate partitions for. The request fails if the query is not root partitionable. For a query to be root partitionable, it needs to satisfy a few conditions. For example, if the query execution plan contains a distributed union operator, then it must be the first operator in the plan. For more information about other conditions, see Read data in parallel. The query request must not contain DML commands, such as INSERT, UPDATE, or DELETE. Use ExecuteStreamingSql with a PartitionedDml transaction for large, partition-friendly DML operations. Corresponds to the JSON property sql

Returns:

  • (String)

#transaction ⇒ Google::Apis::SpannerV1::TransactionSelector

This message is used to select the transaction in which a Read or ExecuteSql call runs. See TransactionOptions for more information about transactions. Corresponds to the JSON property transaction
