an objective-c ORM base on FMDB(https://github.com/ccgus/fmdb) and objective-c runtime.
I am using FMDB as SQLite wrapper.
make your model entity implement BCORMEntityProtocol protocol
@interface ClassEntity : NSObject<BCORMEntityProtocol>
@property (nonatomic,assign)NSInteger classId;
@property (nonatomic,copy)NSString* className;
@end
@implementation ClassEntity
- (NSString *)description
{
return [NSString stringWithFormat:@"[Class:id(%ld) name:(%@)]:%p",self.classId,self.className,self];
}
+(NSString*)tableName
{
return @"class";
}
+(NSDictionary*)tableEntityMapping
{
return @{ @"classId":BCSqliteTypeMakeIntPrimaryKey(@"id", YES),
@"className":BCSqliteTypeMakeTextDefault(@"name", NO,@"Software01")
};
}
@end
it will build a table like this.or just make a mapping
it will build a sql like this:
CREATE TABLE class (
id integer PRIMARY KEY AUTOINCREMENT NOT NULL,
name text NOT NULL DEFAULT('Software01')
);
you can create a new datase file ,or open an existing file like this
BCORMHelper* helper = [[BCORMHelper alloc]initWithDatabaseName:@"test.db"
enties: @[ [ClassEntity class],[StudentEntity class]]];
OR
BCORMHelper* helper = [[BCORMHelper alloc] initWithDatabasePath:@"/Users/BlockCheng/Library/Application Support/test.db"
enties: @[ [ClassEntity class],[StudentEntity class]]];
an example model:
ClassEntity* classeEntity = [ClassEntity new];
classeEntity.className = @"Software02";
classeEntity.classId = 2;
StudentEntity* student = [StudentEntity new];
student.age = 12;
student.score = 80;
student.classId = 2;
student.studentNum = 421125;
student.studentName = @"BlockCheng";
[helper save:classeEntity];
[helper save:student];
BCSqlParameter *queryParam = [[BCSqlParameter alloc] init];
queryParam.entityClass = [StudentEntity class];
queryParam.propertyArray = @[@"age",@"classId",@"score",@"studentName",@"studentNum"];
queryParam.selection = @"classId = ? and studentNum=?";
queryParam.selectionArgs = @[@1,@421128];
queryParam.orderBy = @" studentNum asc";
id entity = [helper queryEntityByCondition:queryParam];
NSLog(@"entity:----%@",entity);
OR simply use
entity = [helper queryEntityByCondition:BCQueryParameterMake([StudentEntity class],
@[@"age",@"classId",@"score",@"studentName",@"studentNum"],@"classId = ? and studentNum=?",
@[@1,@421128],
@" studentNum asc", nil, -1, -1)];
NSLog(@"entity:----%@",entity);
NSArray* entities = [helper queryEntitiesByCondition:
BCQueryParameterMake([ClassEntity class],
nil, @"classId = ?", @[@1],
nil, nil, -1, -1)];
NSLog(@"entities:----%@",entities);
OR
BCSqlParameter *queryParam = [[BCSqlParameter alloc] init];
queryParam.entityClass = [StudentEntity class];
queryParam.selection = @"classId = ?";
queryParam.selectionArgs = @[@1];
NSArray* entities = [helper queryEntitiesByCondition:queryParam];
[helper update:student];
OR with a update condition
[helper updateByCondition:BCUpdateParameterMake([StudentEntity class],@"studentName=?", @[@"new_name"],@"studentNum=?", @[@421125])];
[helper remove:entity];
OR with delete condition
[helper deleteByCondition:BCDeleteParameterMake([StudentEntity class],@"studentNum < ?", @[@421135])];
