Methods

containsParamTypes(String key)

public boolean containsParamTypes(String key)

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.

map<string, .google.spanner.v1.Type> param_types = 5;

Parameter
Name Description
key String
Returns
Type Description
boolean

equals(Object obj)

Parameter
Name Description
obj Object
Returns
Type Description
boolean

getParams()

public Struct getParams()

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.

.google.protobuf.Struct params = 4;

Returns
Type Description
Struct

The params.

getParamsOrBuilder()

public StructOrBuilder getParamsOrBuilder()

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.

.google.protobuf.Struct params = 4;

Returns
Type Description
StructOrBuilder

Overrides

getPartitionOptions()

public PartitionOptions getPartitionOptions()

Additional options that affect how many partitions are created.

.google.spanner.v1.PartitionOptions partition_options = 6;

Returns
Type Description
PartitionOptions

The partitionOptions.

getPartitionOptionsOrBuilder()

public PartitionOptionsOrBuilder getPartitionOptionsOrBuilder()

Additional options that affect how many partitions are created.

.google.spanner.v1.PartitionOptions partition_options = 6;

Returns

getSession()

public String getSession()

Required. The session used to create the partitions.

string session = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
Type Description
String

The session.

getSessionBytes()

public ByteString getSessionBytes()

Required. The session used to create the partitions.

string session = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
Type Description
ByteString

The bytes for session.

getSql()

public String getSql()

Required. The query request to generate partitions for. The request will fail 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.

string sql = 3 [(.google.api.field_behavior) = REQUIRED];

Returns
Type Description
String

The sql.

getSqlBytes()

public ByteString getSqlBytes()

Required. The query request to generate partitions for. The request will fail 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.
