DatabaseExecutor class abstract interface

Executes typed SQLx-style queries against a database connection, transaction, or driver.

Generated DAO code receives a DatabaseExecutor and calls fetchOptional, fetchAll, fetchOne, fetchScalar, or execute depending on the annotated method return type.

Methods

close() → Future<Result<Unit, SqlxError>>
Closes resources owned by this driver.
execute(String sql, List<Object?> parameters) → Future<Result<ExecResult, SqlxError>>
Runs a checked statement and returns execution metadata.
fetchAll<T>(String sql, List<Object?> parameters, RowMapper<T> mapper) → Future<Result<List<T>, SqlxError>>
Runs a checked row query that returns all rows.
fetchOne<T>(String sql, List<Object?> parameters, RowMapper<T> mapper) → Future<Result<T, SqlxError>>
Runs a checked row query that must return exactly one row.
fetchOptional<T>(String sql, List<Object?> parameters, RowMapper<T> mapper) → Future<Result<T?, SqlxError>>
Runs a checked row query that returns zero or one row.
fetchScalar<T>(String sql, List<Object?> parameters) → Future<Result<T, SqlxError>>
Runs a checked scalar query and reads column index zero.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

transaction<T>(Future<Result<T, SqlxError>> fn(Executor tx)) → Future<Result<T, SqlxError>>
