defmodule GoogleApi.Spanner.V1.Model.Statement do
  @moduledoc """
  A single DML statement.

  ## Attributes

  *   `paramTypes` (*type:* `%{optional(String.t) => GoogleApi.Spanner.V1.Model.Type.t}`, *default:* `nil`) - 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.
  *   `params` (*type:* `map()`, *default:* `nil`) - The DML string can contain parameter placeholders. A parameter
      placeholder consists of `'@'` followed by the parameter
      name. Parameter names consist of any combination of 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 an SQL statement with unbound parameters.

      Parameter values are specified using `params`, which is a JSON
      object whose keys are parameter names, and whose values are the
      corresponding parameter values.
  *   `sql` (*type:* `String.t`, *default:* `nil`) - Required. The DML string.
