Reference documentation and code samples for the Cloud Spanner V1 Client class ExecuteSqlRequest.

The request for ExecuteSql and ExecuteStreamingSql.

Generated from protobuf message google.spanner.v1.ExecuteSqlRequest

Namespace

Google \ Cloud \ Spanner \ V1

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ session string

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

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.
↳ sql string

Required. The SQL string.
↳ params Google\Protobuf\Struct

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.
↳ param_types array|Google\Protobuf\Internal\MapField

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 statement parameters. See the definition of Type for more information about SQL types.
↳ resume_token string

If this request is resuming a previously interrupted SQL statement execution, resume_token should be copied from the last 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.
↳ query_mode int

Used to control the amount of debugging information returned in ResultSetStats. If partition_token is set, query_mode can only be set to QueryMode.NORMAL.
↳ partition_token string

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.
↳ seqno int|string

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.
↳ query_options ExecuteSqlRequest\QueryOptions

Query optimizer configuration to use for the given query.
↳ request_options RequestOptions

Common options for this request.
↳ directed_read_options DirectedReadOptions

Directed read options for this request.
↳ data_boost_enabled bool

If this is for a partitioned query and this field is set to true, the request is executed with Spanner Data Boost independent compute resources. If the field is set to true but the request does not set partition_token, the API returns an INVALID_ARGUMENT error.
