QuerySqlDevice(Manager manager, String sql, Object... paramers)

方法概要

限定符和类型	方法和说明
QuerySql	addCondition(Condition cond) Add the query condition, which does not require value, eg: name is not null addCondition("name", Conditions.IS_NOT_NULL)
QuerySql	addCondition(Consumer<List<Condition>> consumer)
QuerySql	addParamer(Object... paramers) Add parameters to your SQL to replace the question mark?
QuerySql	alias(Map<String,String> aliases)
<T> List<T>	entities(Class<T> entityClass)
<T> Optional<T>	entity(Class<T> entityClass)
List<Column>	getQueryColumns() Gets the columns contained in the query result.
<T> List<T>	list() If you need to return a result set instead of a single item; The return type is automatically determined by the constructor.
<T> List<T>	list(Class<T> entityClass)
Optional<Map<String,Object>>	map() The result set encapsulated in the form of Map<String,Object> This will be an acceptable way to get the mapping of SQL result sets
List<Map<String,Object>>	maps() The result set encapsulated in the form of List<Map<String,Object>> This will be an acceptable way to get the mapping of SQL result sets
List<Map<String,Object>>	stream(int count) An extension to the Stream interface，Returns the specified number of results from the SQL statement
void	stream(int bufferSize, Consumer<List<Map<String,Object>>> consumer)
void	stream(int bufferSize, Consumer<Map<String,Object>> rowProcess, Consumer<List<Map<String,Object>>> consumer)
void	stream(int bufferSize, Function<List<Column>,Object> consumer, StreamConsumer datas)
<T> Optional<T>	unique() Returns a single result;The return type is automatically determined based on the constructor, and if you want to return an entity type, add before that
<T> Optional<T>	unique(Class<T> entityClass) Specify entity class mappings
int	update()

QuerySqlDevice

public QuerySqlDevice(Manager manager,
                      String sql,
                      Object... paramers)

方法详细资料

addParamer

public QuerySql addParamer(Object... paramers)

从接口复制的说明: QuerySql

Add parameters to your SQL to replace the question mark?This is a more recommended way to replace string splices

指定者:

addParamer 在接口中 QuerySql

返回:

update

public int update()

指定者:

update 在接口中 QuerySql

list

public <T> List<T> list()

从接口复制的说明: QuerySql

If you need to return a result set instead of a single item; The return type is automatically determined by the constructor. If you want to return an entity type, add the entity type before the QuerySql.list(Class) method

The method is equivalent to the integrator of two methods

指定者:

list 在接口中 QuerySql

QuerySql.entities(Class), QuerySql.maps()

maps

public List<Map<String,Object>> maps()

从接口复制的说明: QuerySql

The result set encapsulated in the form of List<Map<String,Object>>
This will be an acceptable way to get the mapping of SQL result sets

指定者:

maps 在接口中 QuerySql

返回:

List<Map< String,Object>>

stream

public void stream(int bufferSize,
                   Consumer<List<Map<String,Object>>> consumer)

指定者:

stream 在接口中 Stream

stream

public void stream(int bufferSize,
                   Function<List<Column>,Object> consumer,
                   StreamConsumer datas)

指定者:

stream 在接口中 Stream

stream

public List<Map<String,Object>> stream(int count)

从接口复制的说明: QuerySql

An extension to the Stream interface，Returns the specified number of results from the SQL statement

指定者:

stream 在接口中 QuerySql

map

public Optional<Map<String,Object>> map()

从接口复制的说明: QuerySql

The result set encapsulated in the form of Map<String,Object>
This will be an acceptable way to get the mapping of SQL result sets

map 在接口中 QuerySql

返回:

Map< String,Object>

unique

public <T> Optional<T> unique()

从接口复制的说明: QuerySql

Returns a single result;The return type is automatically determined based on the constructor, and if you want to return an entity type, add before that
