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;
| Type | Description |
| Struct | The params.

getParamsOrBuilder()
public StructOrBuilder getParamsOrBuilder()
Parameter names and values that bind to placeholders in the SQL string.

Parameters can appear anywhere that a literal value is expected. The same

getSql()
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 with a
PartitionedDml transaction for large, partition-friendly DML operations.
string sql = 3 [(.google.api.field_behavior) = REQUIRED];
