LKDBSearchHelper

#####说明

• 鉴于移动端不应该存在过于复杂的查询 暂时不支持 have ， join 语法
• 支持 Swift & OC 使用
• 全面支持 NSArray,NSDictionary, ModelClass, NSNumber, NSString, NSDate, NSData, UIColor, UIImage, CGRect, CGPoint, CGSize, NSRange, int,char,float, double, long.. 等属性的自动化操作(插入和查询)

####Requirements

• iOS 7.0+
• ARC only
• FMDB(https://github.com/ccgus/fmdb)
• LKDBHelper-SQLite-ORM(https://github.com/li6185377/LKDBHelper-SQLite-ORM)

#####表例子(OC)

#import "LKDBSearchHelper.h"

@interface TestObj:LKDBPersistenceObject

@property (nonatomic,strong) NSString *name;
@property (nonatomic,assign) int key;
@property (nonatomic,strong) NSString *ads;

@end


@implementation TestObj


+ (NSArray *)transients{
	return @[@"ads"];  //忽略不存库
}

@end

#####表例子(Swift)

import LKDBSearchHelper

class TestObj: LKDBPersistenceObject {
var name:NSString = "" ;
var ads:NSString = "" ;

//此方法必须实现，定义表名
static func getTableName() -> String {
    return "TestObj"
}

open override class func transients() -> [Any] {
    return ["myname"];  //忽略不存库
}

}

#####Model操作例子

//保存
 TestObj *new_obj =[TestObj new];
 new_obj =@"1212";
 [new_obj saveToDB];
 
//更新：被更新的对象必须是通过查询得到的
 TestObj *obj =[select querySingle];
 obj.name =@"1212";
 [obj updateToDB];
 
//删除：被删除的对象必须是通过查询得到的
 TestObj *obj =[select querySingle];
 [obj deleteToDB];

//删除表
 [TestObj dropToDB];

#####查询条件例子

//生成查询，基本定义了几种类型

// SELECT* FROM TestObj WHERE name='11122' AND key=123
LKDBSelect *select = [[[[LKDBSQLite select] from:[TestObj class]]
  where:LKDB_NotEqual_String(@"name",@"11122")]
and:LKDB_NotEqual_Int(@"key", 123)]
                     ;

NSLog(@"%@",[select getQuery]);


// OR name='ssss' 
[select or:LKDB_Equal_String(@"name", @"ssss")];

NSLog(@"%@",[select getQuery]);
                           

//生成一个AND包含条件: AND ( ...... ) 格式
LKDBConditionGroup *andConditionGroup =[select innerAndConditionGroup];

//  AND ( key=3322 OR key=8899 ) 
[[innerAndConditionGroup where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];
  
//再生成一个 OR 包含条件: OR ( ...... ) 格式
LKDBConditionGroup *orConditionGroup =[select innerOrConditionGroup];

//  OR ( key=3322 OR key=8899 ) 
[[innerOrConditionGroup where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];
  
  
//在包含条件里面再生成一个 OR 包含条件: OR ( ...... ) 格式
LKDBConditionGroup *innerOrConditionGroup2 =[innerOrConditionGroup innerOrConditionGroup];

//  OR ( key=3322 OR key=8899 ) 
[[innerOrConditionGroup2 where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];

NSLog(@"%@",[select getQuery]);

//最小结果 结果偏移
// LIMIT 5,5 
[[select offset:5] limit:5];

NSLog(@"%@",[select getQuery]); 

 //查询总数
int count =[select queryCount];

 //查询多个结果
NSArray* list = [select queryList];

 //查询单个结果
TestObj *obj =[select querySingle];

#####删除条件使用例子

//生成删除条件，基本定义了几种类型

// DELETE FROM TestObj WHERE name='11122' AND key=123
LKDBDelete *deleteQuery = [[[[LKDBSQLite delete] from:[TestObj class]]
  where:LKDB_NotEqual_String(@"name",@"11122")]
and:LKDB_NotEqual_Int(@"key", 123)]
                     ;

NSLog(@"%@",[deleteQuery getQuery]);


// OR name='ssss' 
[deleteQuery or:LKDB_Equal_String(@"name", @"ssss")];

NSLog(@"%@",[deleteQuery getQuery]);
                           

//生成一个AND包含条件: AND ( ...... ) 格式
LKDBConditionGroup *andConditionGroup =[deleteQuery innerAndConditionGroup];

//  AND ( key=3322 OR key=8899 ) 
[[innerAndConditionGroup where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];
  
//再生成一个 OR 包含条件: OR ( ...... ) 格式
LKDBConditionGroup *orConditionGroup =[select innerOrConditionGroup];

//  OR ( key=3322 OR key=8899 ) 
[[innerOrConditionGroup where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];
  
  
//在包含条件里面再生成一个 OR 包含条件: OR ( ...... ) 格式
LKDBConditionGroup *innerOrConditionGroup2 =[innerOrConditionGroup innerOrConditionGroup];

//  OR ( key=3322 OR key=8899 ) 
[[innerOrConditionGroup2 where:LKDB_Equal_Int(@"key", 3322)]
  or:LKDB_Equal_Int(@"key", 8899)]];

NSLog(@"%@",[deleteQuery getQuery]);  

 //执行删除
 [deleteQuery execute]; 

#####事物操作例子

 //事物操作
[LKDBSQLite executeForTransaction:^BOOL(void) {
    
    [[LKDBSQLite select] from:[TestObj class]] .........
    
    return YES; //YES 为提交事务，NO 取消事务
}];

或
 
 //事物操作
[[LKDBSQLite transaction] executeForTransaction:^BOOL(void) {
    
    [[LKDBSQLite select] from:[TestObj class]] .........
    
    return YES; //YES 为提交事务，NO 取消事务
}];

model直接操作

LKDBTransaction * transaction = [LKDBSQLite transaction];

[[[transaction  update:obj]  insert:obj]  delete:obj];

[transaction  updateAll:objs];
[transaction  insertAll:objs];
[transaction  deleteAll:objs];

[transaction execute];  //会严格按照操作调用顺序执行

#####条件说明

LKDB_Equal_Int(name,value)     
LKDB_Equal_Float(name,value)        



//条件不等于
LKDB_NotEqual_String(name,value)

//条件小于
LKDB_LessThan_String(name,value)   
LKDB_LessThan_Int(name,value)        
LKDB_LessThan_Float(name,value)    

//条件大于
LKDB_GreaterThan_String(name,value)

//IN条件 
LKDB_IN_String(name,values)
