[−][src]Struct gcp_client::google::spanner::v1::execute_batch_dml_request::Statement
A single DML statement.
Fields
sql: String
Required. The DML string.
params: Option<Struct>
Parameter names and values that bind to placeholders in the DML 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.
param_types: HashMap<String, Type>
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][google.spanner.v1.ExecuteBatchDmlRequest.Statement.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][google.spanner.v1.Type] for more information
about SQL types.
