#param_types ⇒ Hash<String,Google::Apis::SpannerV1::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 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 for more information
about SQL types.
Corresponds to the JSON property paramTypes

#params ⇒ Hash<String,Object>
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.
Corresponds to the JSON property params
