Inheritance

• Object
• ABBaseDao<T>
• BaseDao

Constructors

BaseDao(String tableName, String primaryKey)

Properties

db → Database

no setter

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

table → String

no setter

Methods

addColumn(String field) → void

add the new column for table, the filed just like 'name Text'

clear([String? tableName]) → Future<void>

清空表所有数据

composeIds(List<Object?>? datas) → String

组装Ids

delete(T? t, [String? tableName]) → Future<int>

删除数据

deleteMulti(List<Object?>? datas, [String? tableName]) → Future<int>

删除多个Id

drop([String? tableName]) → Future<void>

删除表所有数据

execute(String sql, [List<Object?>? arguments]) → Future<void>

执行sql语句

fromJson(Map json) → T

inherited

insert(T? t, [String? tableName]) → Future<int>

插入单个model

insertAll(List<T?> t, {String? tableName, String? nullColumnHack, ConflictAlgorithm? conflictAlgorithm = ConflictAlgorithm.replace}) → Future<int>

插入所有model

insertMap(Map<String, dynamic> t, [String? tableName]) → Future<int>

插入map

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onUpgrade(int oldVersion, int newVersion) → FutureOr<void>

增加表更新的方法，这里只是回调到每个dao类中，一个dao类一个表，针对当前表进行更新

query({String? tableName, bool? distinct, List<String>? columns, String? where, List<Object?>? whereArgs, String? groupBy, String? having, String? orderBy, int? limit, int? offset}) → Future<List<T>>

调用sqflite 封装好的查询

queryAll([String? tableName]) → Future<List<T>>

查询该表的所有数据

queryCount([String? tableName]) → Future<int>

查询该表的总数

queryMultiIds(List<Object?>? datas, [String? tableName]) → Future<List<T>>

查询多个ids

queryOne(Object arg, [String? tableName]) → Future<T?>

根据id，查询一个

random([String? tableName]) → Future<T?>

随机获取一个数据

randoms(int count, [String? tableName]) → Future<List<T>>

随机查询一组数据

rawQuery(String sql, [List<Object?>? arguments]) → Future<List<T>>

调用sql语句执行

toString() → String

A string representation of this object.

inherited

update(T? t, [String? tableName]) → Future<int>

更新map

updateAll(List<T>? t, {String? tableName, ConflictAlgorithm? conflictAlgorithm = ConflictAlgorithm.replace}) → Future<int>

更新所有数据库

Operators

operator ==(Object other) → bool

The equality operator.
