Properties

Params

public Struct Params { get; set; }

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:

&quot;WHERE id > @msg_id AND id &lt; @msg_id + 100&quot;

It is an error to execute a SQL statement with unbound parameters.

TypeDescription
Struct

ParamTypes

public MapField<string, Type> ParamTypes { get; }

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.
