public final class Statement implements Serializable

A SQL statement and optional bound parameters that can be executed in a ReadContext.

The SQL query 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 query with placeholders for unbound parameters.

Statements are constructed using a builder. Parameter values are specified by calling Builder#bind(String). For example, code to build a query using the clause above and bind a value to id might look like the following:


 Statement statement = Statement
     .newBuilder("SELECT name WHERE id > @msg_id AND id < @msg_id="" +="" 100")="" .bind("msg_id").to(500)="" .build();="">

Statement instances are immutable.
