VVKeyValue仅用于本工具,不适用常规的Json转对象. 47 | 48 | ## 用法 49 | 此处主要列出一些基本用法,详细用法请阅读代码注释. 50 | 51 | ### 打开/创建数据库文件 52 | ```objc 53 | self.vvdb = [[VVDatabase alloc] initWithPath:dbPath]; 54 | ``` 55 | 56 | ### 定义ORM配置 57 | 1. 手动创建`VVOrmConfig`. 58 | 2. 普通表适配协议`VVOrmable`, fts表适配协议`VVFtsable` 59 | 60 | **注意:** 已移除fts3/4的支持,仅使用fts5 61 | 62 | ### 定义ORM模型 63 | 可自定义表名和存放的数据库文件. 64 | 生成的模型将不在保存在ModelPool中,防止表过多导致内存占用大,需要请自行实现. 65 | 66 | 示例如下: 67 | 68 | ```objc 69 | item.orm = [VVOrm ormWithClass:VVMessage.class name:item.tableName database:item.db]; 70 | 71 | item.ftsOrm = [VVOrm ormWithFtsClass:VVMessage.class name:item.tableName database:item.ftsDb]; 72 | ``` 73 | 74 | ### 增删改查 75 | 使用ORM模型进行增删改查等操作. 76 | 77 | 示例如下: 78 | 79 | ```objc 80 | NSInteger count = [self.mobileModel count:nil]; 81 | 82 | BOOL ret = [self.mobileModel increase:nil field:@"times" value:-1]; 83 | 84 | NSArray *array = [self.mobileModel findAll:nil orderBy:nil limit:10 offset:0]; 85 | 86 | ... 87 | ``` 88 | 89 | ### 生成SQL子句 90 | 现在仅支持非套嵌的字典或字典数组,转换方式如下: 91 | ``` 92 | //where/having : 93 | {field1:val1,field2:val2} --> field1 = "val1" AND field2 = "val2" 94 | [{field1:val1,field2:val2},{field3:val3}] --> (field1 = "val1" AND field2 = "val2") OR (field3 = "val3") 95 | //group by: 96 | [filed1,field2] --> "field1","field2" 97 | //order by 98 | [filed1,field2] --> "field1","field2" ASC 99 | [filed1,field2].desc --> "field1","field2" DESC 100 | ``` 101 | 示例: 102 | ```objc 103 | - (void)testClause 104 | { 105 | VVSelect *select = [VVSelect new]; 106 | select.table(@"mobiles"); 107 | select.where(@"relative".lt(@(0.3)) 108 | .and(@"mobile".gte(@(1600000000))) 109 | .and(@"times".gte(@(0)))); 110 | NSLog(@"%@", select.sql); 111 | select.where(@{ @"city": @"西安", @"relative": @(0.3) }); 112 | NSLog(@"%@", select.sql); 113 | select.where(@[@{ @"city": @"西安", @"relative": @(0.3) }, @{ @"relative": @(0.7) }]); 114 | NSLog(@"%@", select.sql); 115 | select.where(@"relative".lt(@(0.3))); 116 | NSLog(@"%@", select.sql); 117 | select.where(@" where relative < 0.3"); 118 | NSLog(@"%@", select.sql); 119 | select.groupBy(@"city"); 120 | NSLog(@"%@", select.sql); 121 | select.groupBy(@[@"city", @"carrier"]); 122 | NSLog(@"%@", select.sql); 123 | select.groupBy(@" group by city carrier"); 124 | NSLog(@"%@", select.sql); 125 | select.having(@"relative".lt(@(0.2))); 126 | NSLog(@"%@", select.sql); 127 | select.groupBy(nil); 128 | NSLog(@"%@", select.sql); 129 | select.orderBy(@[@"city", @"carrier"]); 130 | NSLog(@"%@", select.sql); 131 | select.orderBy(@" order by relative"); 132 | NSLog(@"%@", select.sql); 133 | select.limit(10); 134 | NSLog(@"%@", select.sql); 135 | select.distinct(YES); 136 | NSLog(@"%@", select.sql); 137 | } 138 | ``` 139 | ### 原生语句查询 140 | ``` 141 | - (NSArray *)query:(NSString *)sql; 142 | 143 | - (NSArray *)query:(NSString *)sql clazz:(Class)clazz; 144 | ``` 145 | 146 | ## 加密数据数据转换(sqlcipher 3.x->4.x) 147 | ```objc 148 | VVDatabase *database = [VVDatabase databaseWithPath:path flags:0 encrypt:@"XXXXX"]; 149 | database.cipherOptions = @[ 150 | @"pragma cipher_page_size = 4096;", ///<3.x的cipher_page_size,默认为1024 151 | @"pragma kdf_iter = 64000;", 152 | @"pragma cipher_hmac_algorithm = HMAC_SHA1;", 153 | @"pragma cipher_kdf_algorithm = PBKDF2_HMAC_SHA1;" 154 | ]; 155 | ``` 156 | 157 | ## Author 158 | 159 | Valo Lee, pozi119@163.com 160 | 161 | ## License 162 | 163 | VVSequelize is available under the MIT license.
