方法详细资料

addCondition

QueryTable 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

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

指定者:

addCondition 在接口中 ConditionAble

参数:

conds - - conditions

返回:

alias

QueryTable alias(Map<String,String> alias)

setFields

QueryTable setFields(List<String> fields)

setFields

QueryTable setFields(String... fields)

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

参数:

fields -

返回:

setExceptFields

QueryTable setExceptFields(String... fields)

All other fields are involved

参数:

fields -

返回:

sort

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

To add sorting

参数:

sorts -

fields -

返回:

unique

<T> Optional<T> unique()

unique

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

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> cls)

entities

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

返回:

Returns a collection of entity class mappings.

map

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

map

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

maps

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

返回:

Returns the result set key pair.

maps

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

参数:

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

返回:

从以下版本开始:

2.24

limit

QueryTable limit(Integer... args)

This is a extraction function

limit(0,10)

This method is usually followed by a maps() or 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

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

int delete()

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

返回:

isExsites

boolean isExsites()

Determine whether the table exists.

返回:

clear

int clear()

Clear the table

返回:

drop

int drop()

Delete table

返回:

updateName

int updateName(String newName)

Modify table name

参数:

newName -

返回:

addColumn

int addColumn(String columnName,
              String type)

Add fields to the table

参数:

columnName -

type -

返回:

copyTo

String copyTo(String newTableName)

参数:

newTableName -

返回:

setQualifier

QueryTable setQualifier(boolean flag)

Whether the qualifier is turned on or not, it is turned on by default

参数:

flag -

返回:

count

int count()

count
