SQLiteORM

基于fmdb构建的orm，支持自动建表，分表，支持属性增删改查自动操作等，同时支持模型的嵌套

Requirements

• ARC

• FMDB

Usages

###定义模型

#####定义消息模型 #import "MUPObject.h"

@interface Message : MUPObject
@property(nonatomic,assign) UInt64 messageID;
@property(nonatomic,copy) NSString *messageContent;
@end


@implementation Message
//设置主键
+(NSArray*)primaryKeys{
  return @[@"messageID"];
}
@end

#####定义user模型 @interface User : MUPObject @property(nonatomic,assign) UInt64 userID; @property(nonatomic,copy) NSString *userName; @property(nonatomic,strong)Message *firstMessage; @property(nonatomic,strong)NSArray *recentMessages; @property(nonatomic,strong)NSDictionary *userDictionary; @end

@implementation User

+(NSArray*)primaryKeys{
    return @[@"userID"];
}
//建立索引,create indices
+(NSArray*)indices
{
    return @[@"userName"];
}
@end

###添加对象,add obj -(void)testAddItems { BOOL reselut = NO;

    Message *message = [Message new];
    message.messageID = 9;
    message.messageContent = @"this is test message 9";
    reselut = [message save];

    
    Message *message1 = [Message new];
    message1.messageID = 10;
    message1.messageContent = @"this is test message 10";
    reselut = [message1 save];
    
    Message *message2 = [Message new];
    message2.messageID = 11;
    message2.messageContent = @"this is test message 11";
    reselut = [message2 save];
    
    //分表
    Message *message3 = [Message new];
    message3.messageID = 12;
    message3.messageContent = @"this is test message 12";
    message3.tableName = @"message12";
    reselut = [message3 save];
}

###添加嵌套对象,add obj -(void)testAddEmbedObj { BOOL reselut = NO; Message *message1 = [Message new]; message1.messageID = 13; message1.messageContent = @"this is test message 13";

    Message *message2 = [Message new];
    message2.messageID = 14;
    message2.messageContent = @"this is test message 14";
    //分表
    Message *message3 = [Message new];
    message3.messageID = 15;
    message3.messageContent = @"this is test message 15";
    message3.tableName = @"message15";
    NSArray *array = [NSArray arrayWithObjects:message2,message3, nil];

    User *user1 = [User new];
    user1.userID = 1;
    user1.userName = @"user1";
    user1.firstMessage = message1;
    user1.userDictionary = @{@"father":@"jhon peter",@"mother":@"taylor swift"};
    user1.recentMessages = array;
  
    reselut = [[MUPSQLiteORM defaultORM] addOrUpdateObject:user1];
}

###删除对象,delete obj -(void)testDeleteObj { BOOL ret = NO; MUPResultSet *resultSet = [User allObjects]; User *user1= [resultSet firstObject]; ret = [user1 remove]; } ###查找对象,find object ,use nspredicate -(void)testFindObj { MUPResultSet *messageSet = [Message allObjects]; NSArray *allMessage = messageSet.dataArray; NSPredicate *pred = [NSPredicate predicateWithFormat:@"messageID > %@",@(10)]; MUPResultSet filterSet = (MUPResultSet)[messageSet objectsWithPredicate:pred]; NSArray *filterArray = filterSet.dataArray;

}

###更新对象,update object -(void)testUpdateObj { BOOL ret = NO; MUPResultSet *userSet = [User allObjects]; User *user = [userSet firstObject]; NSDictionary *updateDic = @{@"userName":@"userNameUpdate",@"firstMessage.messageContent":@"firstMessageContent Changed",@"userDictionary.father":@"lujb"}; ret = [user patch:updateDic]; } ###切换ORM,change orm -(void)testOrmChanged { BOOL ret = NO; MUPSQLiteORM *defaultOrm = [MUPSQLiteORM defaultORM]; NSString *path = [MUPSQLiteORM defaultORMPath];

    path = defaultOrm.ormPath;
    
    NSString *newPath = @"test/newORM.db";
    
    MUPSQLiteORM *newOrm = [MUPSQLiteORM ormWithPath:newPath];
    
    Message *message1 = [Message new];
    message1.messageID = 23;
    message1.messageContent = @"this is test message 23";
    ret = [newOrm addOrUpdateObject:message1];
    
    Message *message2 = [Message new];
    message2.messageID = 24;
    message2.messageContent = @"this is test message 24";
    message2.MUPORM = newOrm;
    ret = [message2 save];
}

###对结果集进行操作,operaion on mupResultSet -(void)testResultOperation { MUPResultSet *messageSet = [Message allObjects]; NSNumber *sum = [messageSet sumOfProperty:@"messageID"]; NSNumber *average = [messageSet averageOfProperty:@"messageID"]; }

支持keypath子查询

-(void)testKeyPathPredicate
{
//    for (int i=20;i<35;i++)
//    {
//        Message *message = [Message new];
//        message.messageID = i;
//        message.messageContent =[NSString stringWithFormat: @"this is test message %d",i ];
//        
//        
//        User *user = [User new];
//        user.userID = i;
//        user.userName = [NSString stringWithFormat: @"user %d",i ];
//        user.firstMessage = message;
//        user.userDictionary = @{@"father":@"jhon peter",@"mother":@"taylor swift"};
//        [[MUPSQLiteORM defaultORM] addOrUpdateObject:user];
//    }

     NSPredicate *predicate = [NSPredicate predicateWithFormat:@"userID > %@ ", @23];
     MUPResultSet *result = [User allObjectsWithPredicate:predicate];

     predicate = [NSPredicate predicateWithFormat:@"firstMessage.messageID in %@ and firstMessage.messageID IN%@", @[@22,@23,@25],@[@23,@29,@30]];
     result = [User allObjectsWithPredicate:predicate];

    predicate = [NSPredicate predicateWithFormat:@"firstMessage.messageID > %@ or userID IN %@",@30,@[@23,@29,@30]];
    result = [User allObjectsWithPredicate:predicate];
}
