readMapFirst

Map<String,Object> readMapFirst(String sql,
                                      Object... parameters)

Reads a first row from the database by mapping the results of the SQL query into an instance of Map.

Types returned from the database will be converted to Java types in the map according with the correspondence defined in ResultSetConverter.toSingleMap(SormOptions, ResultSet, List, List).

Parameters will be set according with the correspondence defined in SqlParametersSetter.setParameters(SormOptions, PreparedStatement, Object... )

パラメータ:

sql - with ordered parameter. The other type parameters (e.g. named parameter, list parameter) could not be used.

parameters - are ordered parameter.

readMapLazy

LazyResultSet<Map<String,Object>> readMapLazy(ParameterizedSql sql)

See readMapLazy(String, Object...)

Returns an LazyResultSet instance containing data from the execution of the provided parametrized SQL and convert it to Stream, List, and so on.

Types returned from the database will be converted to Java types in the map according with the correspondence defined in ResultSetConverter.toSingleMap(SormOptions, ResultSet, List, List).

Parameters will be set according with the correspondence defined in SqlParametersSetter.setParameters(SormOptions, PreparedStatement, Object... )

readMapList

List<Map<String,Object>> readMapList(String sql,
                                           Object... parameters)

Reads a list of objects from the database by mapping the SQL execution results to instances of Map containing data from the execution of the provided parameterized SQL and

Types returned from the database will be converted to Java types in the map according with the correspondence defined in ResultSetConverter.toSingleMap(SormOptions, ResultSet, List, List).

Parameters will be set according with the correspondence defined in SqlParametersSetter.setParameters(SormOptions, PreparedStatement, Object... )

readMapOne

Map<String,Object> readMapOne(String sql,
                                    Object... parameters)

Reads a first row from the database by mapping the results of the SQL query into an instance of Map. If the given SQL statement gets non-unique result, SormException is thrown.
