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>> conds)
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
<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()

addParamer

QuerySql addParamer(Object... paramers)

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

参数:

paramers -

返回:

update

int update()

list

<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. If you want to return an entity type, add the entity type before the list(Class) method

The method is equivalent to the integrator of two methods

另请参阅:

entities(Class), maps()

list

<T> List<T> list(Class<T> entityClass)

entities

<T> List<T> entities(Class<T> entityClass)

返回:

Returns a collection of entity class mappings.

maps

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

返回:

List<Map< String,Object>>

map

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

返回:

Map< String,Object>

unique

<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

返回:

unique

<T> Optional<T> unique(Class<T> entityClass)

Specify entity class mappings

参数:

entityClass - - Be sure to include an Id annotation to declare the primary key

返回:

entity

<T> Optional<T> entity(Class<T> entityClass)

getQueryColumns

List<Column> getQueryColumns()

Gets the columns contained in the query result.

返回:

addCondition

QuerySql addCondition(Condition cond)

从接口复制的说明: ConditionAble

Add the query condition, which does not require value,
eg: name is not null

addCondition("name", Conditions.IS_NOT_NULL)

指定者:

addCondition 在接口中 ConditionAble

返回:

addCondition

QuerySql addCondition(Consumer<List<Condition>> conds)

指定者:

addCondition 在接口中 ConditionAble

参数:

conds - - conditions

返回:

stream

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

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

参数:

count -

alias

QuerySql alias(Map<String,String> aliases)
