QueryTableMongodb

public QueryTableMongodb(Manager<MongoDBTemplate> manager,
                         String tableName)

方法详细资料

stream

public void stream(int buffersize,
                   Consumer<List<? extends Map<String,Object>>> consumer)

指定者:

stream 在接口中 QueryTable

addCondition

public QueryTable addCondition(Condition cond)

指定者:

addCondition 在接口中 QueryTable

addCondition

public QueryTable addCondition(Consumer<List<Condition>> conds)

指定者:

addCondition 在接口中 QueryTable

alias

public QueryTable alias(Map<String,String> alias)

指定者:

alias 在接口中 QueryTable

setFields

public QueryTable setFields(String... fields)

从接口复制的说明: QueryTable

Sets the fields that participate in the operation, with the highest priority to override the fields of the entity class

指定者:

setFields 在接口中 QueryTable

返回:

setFields

public QueryTable setFields(List<String> fields)

指定者:

setFields 在接口中 QueryTable

setExceptFields

public QueryTable setExceptFields(String... fields)

从接口复制的说明: QueryTable

All other fields are involved

指定者:

setExceptFields 在接口中 QueryTable

返回:

sort

public QueryTable sort(Sorts sorts,
                       String... fields)

从接口复制的说明: QueryTable

To add sorting

指定者:

sort 在接口中 QueryTable

返回:

list

public <T> List<T> list()

从接口复制的说明: QueryTable

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 QueryTable.list(Class) method

The method is equivalent to the integrator of two methods

指定者:

list 在接口中 QueryTable

另请参阅:

QueryTable.entities(Class), QueryTable.maps()

list

public <T> List<T> list(Class<T> cls)

指定者:

list 在接口中 QueryTable

entities

public <T> List<T> entities(Class<T> cls)

指定者:

entities 在接口中 QueryTable

返回:

Returns a collection of entity class mappings.

unique

public <T> Optional<T> unique()

从接口复制的说明: QueryTable

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 or use QueryTable.unique(Class)

指定者:

unique 在接口中 QueryTable

返回:

createView

public void createView(String viewName)

指定者:

createView 在接口中 QueryTable

unique

public <T> Optional<T> unique(Class<T> cls)

从接口复制的说明: QueryTable

Returns a single result;The return type is automatically determined based on the constructor

指定者:

unique 在接口中 QueryTable

返回:

map

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

指定者:

map 在接口中 QueryTable

maps

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

指定者:

maps 在接口中 QueryTable

返回:

Returns the result set key pair.

maps

public <T extends Map<String,Object>> List<T> maps(Map<String,String> alias)

指定者:

maps 在接口中 QueryTable

参数:

alias - - Aliased key-value pairs, returned as aliased key-value if matched

返回:

limit

public QueryTable limit(Integer... args)

从接口复制的说明: QueryTable

This is a extraction function

limit(0,10)

This method is usually followed by a QueryTable.maps() or QueryTable.list() method

Different databases will have different implementations, so refer to the database functions you're currently using, and if you don't support limit, you'll default to pulling the corresponding result set from the result set

指定者:

limit 在接口中 QueryTable

参数:

args - - If you're using MYSQL or ORACLE or SQLITE you can go to limit(0,100), if you're using SQLSERVER you'll go to limit(100) and it'll convert to top 100

返回:

QueryTable

delete

public int delete()

从接口复制的说明: QueryTable

Condition deletion, if no condition, is equivalent to clearing the table.
