The request for [ExecuteBatchDml][google.spanner.v1.Spanner.ExecuteBatchDml].

Value parameters

requestOptions

Common options for this request.

seqno

Required. A per-transaction sequence number used to identify this request. This field makes each request idempotent such that if the request is received multiple times, at most one will succeed. The sequence number must be monotonically increasing within the transaction. If a request arrives for the first time with an out-of-order sequence number, the transaction may be aborted. Replays of previously handled requests will yield the same response as the first execution.

session

Required. The session in which the DML statements should be performed.

statements

Required. The list of statements to execute in this batch. Statements are executed serially, such that the effects of statement i are visible to statement i+1. Each statement must be a DML statement. Execution stops at the first failed statement; the remaining statements are not executed. Callers must provide at least one statement.

transaction

Required. The transaction to use. Must be a read-write transaction. To protect against replays, single-use transactions are not supported. The caller must either supply an existing transaction ID or begin a new transaction.

final case class ExecuteBatchDmlResponse(resultSets: Seq[ResultSet], status: Option[Status], unknownFields: UnknownFieldSet) extends GeneratedMessage, Updatable[ExecuteBatchDmlResponse]

The response for [ExecuteBatchDml][google.spanner.v1.Spanner.ExecuteBatchDml]. Contains a list of [ResultSet][google.spanner.v1.ResultSet] messages, one for each DML statement that has successfully executed, in the same order as the statements in the request. If a statement fails, the status in the response body identifies the cause of the failure.

The response for [ExecuteBatchDml][google.spanner.v1.Spanner.ExecuteBatchDml]. Contains a list of [ResultSet][google.spanner.v1.ResultSet] messages, one for each DML statement that has successfully executed, in the same order as the statements in the request. If a statement fails, the status in the response body identifies the cause of the failure.

To check for DML statements that failed, use the following approach:

  1. Check the status in the response message. The [google.rpc.Code][google.rpc.Code] enum value OK indicates that all statements were executed successfully.
  2. If the status was not OK, check the number of result sets in the response. If the response contains N [ResultSet][google.spanner.v1.ResultSet] messages, then statement N+1 in the request failed.

Example 1:

  • Request: 5 DML statements, all executed successfully.
  • Response: 5 [ResultSet][google.spanner.v1.ResultSet] messages, with the status OK.

Example 2:

  • Request: 5 DML statements. The third statement has a syntax error.
  • Response: 2 [ResultSet][google.spanner.v1.ResultSet] messages, and a syntax error (INVALID_ARGUMENT) status. The number of [ResultSet][google.spanner.v1.ResultSet] messages indicates that the third statement failed, and the fourth and fifth statements were not executed.

Value parameters

resultSets

One [ResultSet][google.spanner.v1.ResultSet] for each statement in the request that ran successfully, in the same order as the statements in the request. Each [ResultSet][google.spanner.v1.ResultSet] does not contain any rows. The [ResultSetStats][google.spanner.v1.ResultSetStats] in each [ResultSet][google.spanner.v1.ResultSet] contain the number of rows modified by the statement. Only the first [ResultSet][google.spanner.v1.ResultSet] in the response contains valid [ResultSetMetadata][google.spanner.v1.ResultSetMetadata].

status

If all DML statements are executed successfully, the status is OK. Otherwise, the error status of the first failed statement.

The request for [ExecuteSql][google.spanner.v1.Spanner.ExecuteSql] and [ExecuteStreamingSql][google.spanner.v1.Spanner.ExecuteStreamingSql].

The request for [ExecuteSql][google.spanner.v1.Spanner.ExecuteSql] and [ExecuteStreamingSql][google.spanner.v1.Spanner.ExecuteStreamingSql].

Value parameters

dataBoostEnabled

If this is for a partitioned query and this field is set to true, the request will be executed via Spanner independent compute resources. If the field is set to true but the request does not set partition_token, the API will return an INVALID_ARGUMENT error.

paramTypes

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][google.spanner.v1.ExecuteSqlRequest.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 statement parameters. See the definition of [Type][google.spanner.v1.Type] for more information about SQL types.

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 must conform to the naming requirements of identifiers as specified at https://cloud.google.com/spanner/docs/lexical#identifiers. 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.

partitionToken

If present, results will be restricted to the specified partition previously created using PartitionQuery(). There must be an exact match for the values of fields common to this message and the PartitionQueryRequest message used to create this partition_token.

queryMode

Used to control the amount of debugging information returned in [ResultSetStats][google.spanner.v1.ResultSetStats]. If [partition_token][google.spanner.v1.ExecuteSqlRequest.partition_token] is set, [query_mode][google.spanner.v1.ExecuteSqlRequest.query_mode] can only be set to [QueryMode.NORMAL][google.spanner.v1.ExecuteSqlRequest.QueryMode.NORMAL].

queryOptions

Query optimizer configuration to use for the given query.

requestOptions

Common options for this request.

resumeToken

If this request is resuming a previously interrupted SQL statement execution, resume_token should be copied from the last [PartialResultSet][google.spanner.v1.PartialResultSet] yielded before the interruption. Doing this enables the new SQL statement execution to resume where the last one left off. The rest of the request parameters must exactly match the request that yielded this token.

seqno

A per-transaction sequence number used to identify this request. This field makes each request idempotent such that if the request is received multiple times, at most one will succeed. The sequence number must be monotonically increasing within the transaction. If a request arrives for the first time with an out-of-order sequence number, the transaction may be aborted. Replays of previously handled requests will yield the same response as the first execution. Required for DML statements. Ignored for queries.

session

Required. The session in which the SQL query should be performed.

sql

Required. The SQL string.

transaction

The transaction to use. For queries, if none is provided, the default is a temporary read-only transaction with strong concurrency. Standard DML statements require a read-write transaction. To protect against replays, single-use transactions are not supported. The caller must either supply an existing transaction ID or begin a new transaction. Partitioned DML requires an existing Partitioned DML transaction ID.

The request for [PartitionQuery][google.spanner.v1.Spanner.PartitionQuery]

Value 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 BYTES and values of type STRING both appear in [params][google.spanner.v1.PartitionQueryRequest.params] as JSON strings.

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

Additional options that affect how many partitions are created.

session

Required. The session used to create the partitions.

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.

transaction

Read only snapshot transactions are supported, read/write and single use transactions are not.

If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order (if [index][google.spanner.v1.ReadRequest.index] is non-empty). If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is not empty, rows will be yielded in an unspecified order. It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.

limit

If greater than zero, only the first limit rows are yielded. If limit is zero, the default is no limit. A limit cannot be specified if partition_token is set.

partitionToken

If present, results will be restricted to the specified partition previously created using PartitionRead(). There must be an exact match for the values of fields common to this message and the PartitionReadRequest message used to create this partition_token.

requestOptions

Common options for this request.

resumeToken

If this request is resuming a previously interrupted read, resume_token should be copied from the last [PartialResultSet][google.spanner.v1.PartialResultSet] yielded before the interruption. Doing this enables the new read to resume where the last read left off. The rest of the request parameters must exactly match the request that yielded this token.

session

Required. The session in which the read should be performed.

table

Required. The name of the table in the database to be read.

transaction

The transaction to use. If none is provided, the default is a temporary read-only transaction with strong concurrency.

Common request options for various APIs.

Common request options for various APIs.

Value parameters

priority

Priority for the request.

requestTag

A per-request tag which can be applied to queries or reads, used for statistics collection. Both request_tag and transaction_tag can be specified for a read or query that belongs to a transaction. This field is ignored for requests where it's not applicable (e.g. CommitRequest). Legal characters for request_tag values are all printable characters (ASCII 32 - 126) and the length of a request_tag is limited to 50 characters. Values that exceed this limit are truncated. Any leading underscore (_) characters will be removed from the string.

transactionTag

A tag used for statistics collection about this transaction. Both request_tag and transaction_tag can be specified for a read or query that belongs to a transaction. The value of transaction_tag should be the same for all requests belonging to the same transaction. If this request doesn't belong to any transaction, transaction_tag will be ignored. Legal characters for transaction_tag values are all printable characters (ASCII 32 - 126) and the length of a transaction_tag is limited to 50 characters. Values that exceed this limit are truncated. Any leading underscore (_) characters will be removed from the string.
