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.

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.

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.

| Returns |
|---|
| Type | Description |
ByteString | The bytes for session.
|
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, the first
operator in the query execution plan must be a distributed union operator.
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.
