核心对象
- PaintingliteSessionManager ： 基本操做管理者(库操做 | 表操做)
- PaintingliteExec ： 执行操做
- PaintingliteBackUpManager ： 数据库备份管理者
- PaintingliteSplitTable ： 拆分操做
- PaintinglitePressureOS ： 压力测试
数据库操做(PaintingliteSessionManager)
1.建库
建立PaintingliteSessionManager,经过管理者建立数据库。
- (Boolean)openSqlite:(NSString *)fileName;
- (Boolean)openSqlite:(NSString *)fileName completeHandler:(void(^ __nullable)(NSString *filePath,PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
Paintinglite具备良好的处理机制,经过传入数据库名称进行建立数据库,即便数据库后缀不规范,它仍能建立出.db后缀的数据库。数据库
[self.sessionM openSqlite:@"sqlite"];
[self.sessionM openSqlite:@"sqlite02.db"];
[self.sessionM openSqlite:@"sqlite03.image"];
[self.sessionM openSqlite:@"sqlite04.text"];
[self.sessionM openSqlite:@"sqlite05.."];
复制代码
得到建立数据库的绝对路径。数组
[self.sessionM openSqlite:@"sqlite" completeHandler:^(NSString * _Nonnull filePath, PaintingliteSessionError * _Nonnull error, Boolean success) {
if (success) {
NSLog(@"%@",filePath);
}
}];
复制代码
2.关闭库
- (Boolean)releaseSqlite;
- (Boolean)releaseSqliteCompleteHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
3.建立表
- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)createTableForName:(NSString *)tableName content:(NSString *)content;
- (Boolean)createTableForName:(NSString *)tableName content:(NSString *)content completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)createTableForObj:(id)obj createStyle:(PaintingliteDataBaseOptionsCreateStyle)createStyle;
- (Boolean)createTableForObj:(id)obj createStyle:(PaintingliteDataBaseOptionsCreateStyle)createStyle completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
建立表的三种方式：缓存
- SQL建立
[self.sessionM execTableOptForSQL:@"CREATE TABLE IF NOT EXISTS cart(UUID VARCHAR(20) NOT NULL PRIMARY KEY,shoppingName TEXT,shoppingID INT(11))" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success) {
if (success) {
NSLog(@"===CREATE TABLE SUCCESS===");
}
}];
复制代码
- 表名建立
[self.sessionM createTableForName:@"student" content:@"name TEXT,age INTEGER"];
复制代码
- 对象建立
User *user = [[User alloc] init];
[self.sessionM createTableForObj:user createStyle:PaintingliteDataBaseOptionsUUID];
复制代码
对象建立能够自动生成主键:安全
| 主键 | 类型 |
|---|---|
| UUID | 字符串 |
| ID | 数值 |
4.更新表
- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableForName:(NSString *__nonnull)oldName newName:(NSString *__nonnull)newName;
- (BOOL)alterTableForName:(NSString *__nonnull)oldName newName:(NSString *__nonnull)newName completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableAddColumnWithTableName:(NSString *)tableName columnName:(NSString *__nonnull)columnName columnType:(NSString *__nonnull)columnType;
- (BOOL)alterTableAddColumnWithTableName:(NSString *)tableName columnName:(NSString *__nonnull)columnName columnType:(NSString *__nonnull)columnType completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (BOOL)alterTableForObj:(id)obj;
- (BOOL)alterTableForObj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
更新表三种方式:session
-
SQL更新框架
-
表名更新 [ 表名称 | 表字段 ]
[self.sessionM alterTableForName:@"cart" newName:@"carts"];
[self.sessionM alterTableAddColumnWithTableName:@"carts" columnName:@"newColumn" columnType:@"TEXT"];
复制代码
- 对象更新 更新User表操做
#import <Foundation/Foundation.h>
NS_ASSUME_NONNULL_BEGIN
@interface User : NSObject
@property (nonatomic,strong)NSString *name;
@property (nonatomic,strong)NSNumber *age;
@property (nonatomic,strong)NSMutableArray<id> *mutableArray;
@end
NS_ASSUME_NONNULL_END
复制代码
根据表和对象的映射关系,自动根据对象更新表字段。
User *user = [[User alloc] init];
[self.sessionM alterTableForObj:user];
复制代码
5.删除操做
- (Boolean)execTableOptForSQL:(NSString *)sql;
- (Boolean)execTableOptForSQL:(NSString *)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)dropTableForTableName:(NSString *)tableName;
- (Boolean)dropTableForTableName:(NSString *)tableName completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)dropTableForObj:(id)obj;
- (Boolean)dropTableForObj:(id)obj completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
删除表的三种方法:
- SQL操做
- 表名删除
[self.sessionM execTableOptForSQL:@"DROP TABLE carts" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success) {
if (success) {
NSLog(@"===DROP TABLE SUCCESS===");
}
}];
复制代码
- 对象删除
User *user = [[User alloc] init];
[self.sessionM dropTableForObj:user];
复制代码
表操做
1.查询
查询能够提供查询结果用数组封装或者采用对象直接封装的特色。
- 普通查询
- 通常查询
- (NSMutableArray *)execQuerySQL:(NSString *__nonnull)sql;
- (Boolean)execQuerySQL:(NSString *__nonnull)sql completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success,NSMutableArray<NSDictionary *> *resArray))completeHandler;
复制代码
[self.sessionM execQuerySQL:@"SELECT * FROM student" completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray<NSDictionary *> * _Nonnull resArray) {
if (success) {
for (NSDictionary *dict in resArray) {
NSLog(@"%@",dict);
}
}
}];
复制代码
2020-06-27 15:35:45.967569+0800 Paintinglite[5805:295051] { age = 21; name = CreaterOS; } 2020-06-27 15:35:45.967760+0800 Paintinglite[5805:295051] { age = 19; name = Painting; } 2020-06-27 15:35:45.967879+0800 Paintinglite[5805:295051] { age = 21; name = CreaterOS; }
-
封装查询
封装查询能够将查询结果封装到与表字段相对应的对象中。
- (id)execQuerySQL:(NSString *__nonnull)sql obj:(id)obj;
- (Boolean)execQuerySQL:(NSString *__nonnull)sql obj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray,NSMutableArray<id> *resObjList))completeHandler;
复制代码
Student *stu = [[Student alloc] init];
[self.sessionM execQuerySQL:@"SELECT * FROM student" obj:stu completeHandler:^(PaintingliteSessionError * _Nonnull error, Boolean success, NSMutableArray<NSDictionary *> * _Nonnull resArray, NSMutableArray<id> * _Nonnull resObjList) {
if (success) {
for (Student *stu in resObjList) {
NSLog(@"stu.name = %@ and stu.age = %@",stu.name,stu.age);
}
}
}];
复制代码

- (Boolean)insertWithObj:(id)obj completeHandler:(void(^ __nullable)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
- SQL插入
[self.sessionM insert:@"INSERT INTO student(name,age) VALUES('CreaterOS',21),('Painting',19)"];
复制代码
- 对象插入
#import <Foundation/Foundation.h>
NS_ASSUME_NONNULL_BEGIN
@interface Student : NSObject
@property (nonatomic,strong)NSString *name;
@property (nonatomic,strong)NSNumber *age;
@end
NS_ASSUME_NONNULL_END
复制代码
Student *stu = [[Student alloc] init];
stu.name = @"ReynBryant";
stu.age = [NSNumber numberWithInteger:21];
[self.sessionM insertWithObj:stu completeHandler:nil];
复制代码
对于庞大数据量,Paintinglit仍可以表现出良好的效率，经过一次性读入1千6百万条数据只耗时6ms-7ms。
3.更新数据
- (Boolean)update:(NSString *__nonnull)sql;
- (Boolean)update:(NSString *__nonnull)sql completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
- (Boolean)updateWithObj:(id)obj condition:(NSString *__nonnull)condition completeHandler:(void(^)(PaintingliteSessionError *error,Boolean success))completeHandler;
复制代码
- SQL更新数据
[self.sessionM update:@"UPDATE student SET name = 'Painting' WHERE name = 'ReynBryant'"];
复制代码
-
对象更新
Student *stu = [[Student alloc] init]; stu.name = @"CreaterOS"; [self.sessionM updateWithObj:stu condition:@"age = 21" completeHandler:nil]; 复制代码
增长更新操做,能够经过对象传值方式进行更新 例如： User *user = [[User alloc] init]; user.name = @"CreaterOS"; user.age = 21;
4.删除数据

PQL语法(PaintingliteSessionManager)
经过PQL语句,Paintinglite能够自动帮您完成SQL语句的书写。
PQL语法规则(大写 | 类名必定要和表关联) FROM + 类名称 + [条件]
- (id)execPrepareStatementPQL;
- (Boolean)execPrepareStatementPQLWithCompleteHandler:(void(^)(PaintingliteSessionError *error,Boolean success,NSMutableArray *resArray,NSMutableArray<id>* resObjList))completeHandler;

聚合函数(PaintingliteAggregateFunc)
Paintinglite封装Sqlite3聚合函数,自动写入SQL语句就能够获得聚合结果。
- Count
[self.aggreageteF count:[self.sessionM getSqlite3] tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, NSUInteger count) {
if (success) {
NSLog(@"%zd",count);
}
}];
复制代码
- Max
[self.aggreageteF max:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double max) {
if (success) {
NSLog(@"%.2f",max);
}
}];
复制代码
- Min
[self.aggreageteF min:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double min) {
if (success) {
NSLog(@"%.2f",min);
}
}];
复制代码
- Sum
[self.aggreageteF sum:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double sum) {
if (success) {
NSLog(@"%.2f",sum);
}
}];
复制代码
- Avg
[self.aggreageteF avg:[self.sessionM getSqlite3] field:@"age" tableName:@"eletest" completeHandler:^(PaintingliteSessionError * _Nonnull sessionerror, Boolean success, double avg) {
if (success) {
NSLog(@"%.2f",avg);
}
}];
复制代码
事务(PaintingliteTransaction)
Sqlite3开发默认一条插入语句是一个事务,假设有多个插入语句则会重复开起事务,这对资源消耗是巨大的,Paintinglite提供了开起事务的操做(显示事务)。
+ (void)begainPaintingliteTransaction:(sqlite3 *)ppDb;
+ (void)commit:(sqlite3 *)ppDb;
+ (void)rollback:(sqlite3 *)ppDb;
复制代码
平常开发结合
@try { } @catch (NSException *exception) { } @finally { }
使用
级联操做(PaintingliteCascadeShowerIUD)
- (Boolean)cascadeInsert:(sqlite3 *)ppDb obj:(id)obj completeHandler:(void (^ __nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;
- (Boolean)cascadeUpdate:(sqlite3 *)ppDb obj:(id)obj condatation:(NSArray<NSString *> * __nonnull)condatation completeHandler:(void (^__nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;
- (Boolean)cascadeDelete:(sqlite3 *)ppDb obj:(id)obj condatation:(NSArray<NSString *> * __nonnull)condatation completeHandler:(void (^__nullable)(PaintingliteSessionError *sessionError,Boolean success,NSMutableArray *resArray))completeHandler;
复制代码
级联分为三个部分:
- 插入
级联插入操做,咱们须要将两个有关系的表经过可变数组进行链接,例如: user表和student表有联系, 一个user能够包含多个student
那么,能够在user中设置可变数据保存多个student,而后将user对象交给Paintinglite就能够一次写入多个表的数据。
User *user = [[User alloc] init];
user.name = @"Jay";
user.age = [NSNumber numberWithInteger:40];
user.studentsArray = [NSMutableArray array];
Student *student = [[Student alloc] init];
student.name = @"Hony";
student.age = [NSNumber numberWithInteger:30];
Student *student1 = [[Student alloc] init];
student1.name = @"Jack";
student1.age = [NSNumber numberWithInteger:41];
[user.studentsArray addObject:student];
[user.studentsArray addObject:student1];
[self.cascade cascadeInsert:[self.sessionM getSqlite3] obj:user completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
if (success) {
NSLog(@"%@",resArray);
}
}];
复制代码
- 更新 做用和级联插入相同,传入user对象,包含student表的集合,将修改条件以数组方式传入,Paintinglite能够自动实现多表的更新。(条件数组对应的多个表的不一样条件)
name = 'CreaterOS' 对应user表
name = 'OS...' 对应student表
[self.cascade cascadeUpdate:[self.sessionM getSqlite3] obj:user condatation:@[@"WHERE name = 'CreaterOS'",@"WHERE name = 'OS...'"] completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
if (success) {
NSLog(@"%@",resArray);
}
}];
复制代码
- 删除
[self.cascade cascadeDelete:[self.sessionM getSqlite3] obj:user condatation:@[@"name = 'WHY'",@"name = 'YHD...'"] completeHandler:^(PaintingliteSessionError * _Nonnull sessionError, Boolean success, NSMutableArray * _Nonnull resArray) {
if (success) {
NSLog(@"%@",resArray);
}
}];
复制代码
日志模式(PaintingliteLog)
Paintinglite为开发者提供了日志记录功能,能够记录开发中对sqlite3数据的关键操做,而且标有时间戳,开发者能够经过数据库名称轻松读取日志,也能够根据须要的时间节点或者成功失败的状态选择性的读取日志。方便了软件上线后的调试。
- (void)readLogFile:(NSString *__nonnull)fileName;
- (void)readLogFile:(NSString *)fileName dateTime:(NSDate *__nonnull)dateTime;
- (void)readLogFile:(NSString *)fileName logStatus:(PaintingliteLogStatus)logStatus;
- (void)removeLogFile:(NSString *)fileName;
复制代码
数据库备份(PaintingliteBackUpManager)
数据库迁移是开发人员常常关心的问题,对于sqlite3移植客户端SQL Server MySQL 和 Orcale一直是一个头疼的问题。Paintinglite很是友好的为开发者提供了四种数据库的备份文件,包括从建库到插入数据,Paintinglite为开发者写入了备份文件,开发者只须要上传这些sql文件并运行就能够获得和移动设备彻底同样的数据。
PaintingliteBackUpSqlite3,
PaintingliteBackUpMySql,
PaintingliteBackUpSqlServer,
PaintingliteBackUpORCALE
复制代码
- (Boolean)backupDataBaseWithName:(sqlite3 *)ppDb sqliteName:(NSString *)sqliteName type:(PaintingliteBackUpManagerDBType)type completeHandler:(void(^ __nullable)(NSString *saveFilePath))completeHandler;
复制代码
拆分表(PaintingliteSplitTable)
对于过大的数据量的表查询耗时操做是巨大的,Paintinglite测试阶段提供了拆分表的操做,将大表拆分红为多个小表,拆分的数额由开发者本身决定。 Paintinglite首次提供拆分表操做,模块尚在测试,后期版本迭代会重点优化这部分的资源消耗和CPU占用率问题。
/**
* tableName: 数据库名称
* basePoint: 拆分个数
*/
- (Boolean)splitTable:(sqlite3 *)ppDb tabelName:(NSString *__nonnull)tableName basePoint:(NSUInteger)basePoint;
复制代码
- 查询操做
