Methods

containsParamTypes(String key)

public abstract 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

getParamTypes()

public abstract Map<String,Type> getParamTypes()

Use #getParamTypesMap() instead.

Returns
Type	Description
Map<String,Type>

getParamTypesCount()

public abstract int getParamTypesCount()

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;

Returns
Type	Description
int

getParamTypesMap()

getParamTypesOrDefault(String key, Type defaultValue)

public abstract Type getParamTypesOrDefault(String key, Type defaultValue)

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.

getParamTypesOrThrow(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.

Parameter
Name	Description
key	String

Returns
Type	Description
Type

getParams()

public abstract 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 abstract 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

getPartitionOptions()

public abstract 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 abstract PartitionOptionsOrBuilder getPartitionOptionsOrBuilder()

Additional options that affect how many partitions are created.

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

Returns
Type	Description
PartitionOptionsOrBuilder

getSession()

public abstract 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 abstract 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 abstract 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 abstract 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.

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
ByteString	The bytes for sql.

getTransaction()

public abstract TransactionSelector getTransaction()

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

.google.spanner.v1.TransactionSelector transaction = 2;

Returns
Type	Description
TransactionSelector	The transaction.

getTransactionOrBuilder()

public abstract TransactionSelectorOrBuilder getTransactionOrBuilder()

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

.google.spanner.v1.TransactionSelector transaction = 2;

Returns
Type	Description
TransactionSelectorOrBuilder

hasParams()

public abstract boolean hasParams()

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
boolean	Whether the params field is set.

hasPartitionOptions()

public abstract boolean hasPartitionOptions()

Additional options that affect how many partitions are created.

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

Returns
Type	Description
boolean	Whether the partitionOptions field is set.

hasTransaction()

public abstract boolean hasTransaction()

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

.google.spanner.v1.TransactionSelector transaction = 2;

Returns
Type	Description
boolean	Whether the transaction field is set.
