|
||||
FreeSql 支持 MySql/SqlServer/PostgreSQL 数据库技术实现。<br />
|
||||
FreeSql 打造 .NETCore 最方便的 ORM，dbfirst codefirst混合使用，codefirst模式下的开发阶段，建好实体不用执行任何操作，就能创建表和修改字段，dbfirst模式下提供api+模板，自定义生成代码，作者提供了3种模板。<br />

|
||||
```csharp
|
||||
IFreeSql fsql = new FreeSql.FreeSqlBuilder()
|
||||
.UseConnectionString(FreeSql.DataType.MySql, "Data Source=127.0.0.1;Port=3306;User ID=root;Password=root;Initial Catalog=cccddd;Charset=utf8;SslMode=none;Max pool size=10")
|
||||
.Build();
|
||||
```
|
||||
|
||||
### 自动同步实体结构【开发环境必备】
|
||||
|
||||
自动同步实体结构到数据库，程序运行中检查实体表是否存在，然后创建或修改
|
||||
|
||||
```csharp
|
||||
fsql.CodeFirst.IsAutoSyncDataStructure = true;
|
||||
```
|
||||
|
||||
> 此功能默认为开启状态，发布正式环境后，请修改此设置
|
||||
|
||||
> 虽然【自动同步实体结构】功能开发非常好用，但是有个坏处，就是数据库后面会很乱，没用的字段一大堆
|
||||
|
||||
### 手工同步实体结构
|
||||
|
||||

|
||||
| - | - | - | - |
|
||||
| | √ | √ | X |

|
||||
| | √ | √ | √ | √ | √ | X |
|
||||
|
||||
> 为了保证安全，不提供删除字段
|
||||
|
||||
|
||||
1、提供方法对比实体，与数据库中的变化部分
|
||||
|
||||
```csharp
|
||||
var t1 = mysql.CodeFirst.GetComparisonDDLStatements<Topic>();
|
||||
|
||||
class Topic {
|
||||
[Column(IsIdentity = true, IsPrimary = true)]
|
||||
public int Id { get; set; }
|
||||
public int Clicks { get; set; }
|
||||
public TestTypeInfo Type { get; set; }
|
||||
public string Title { get; set; }
|
||||
public DateTime CreateTime { get; set; }
|
||||
public ushort fusho { get; set; }
|
||||
}
|
||||
```
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS `cccddd`.`Topic` (
|
||||
`Id` INT(11) NOT NULL AUTO_INCREMENT,
|
||||
`Clicks` INT(11) NOT NULL,
|
||||
`Title` VARCHAR(255),
|
||||
`CreateTime` DATETIME NOT NULL,
|
||||
`fusho` SMALLINT(5) UNSIGNED NOT NULL,
|
||||
PRIMARY KEY (`Id`)
|
||||
) Engine=InnoDB CHARACTER SET utf8;
|
||||
```
|
||||
|
||||
2、指定实体的表名
|
||||
|
||||
指定 Name 后，实体类名变化不影响数据库对应的表
|
||||
```csharp
|
||||
[Table(Name = "tb_topic111")]
|
||||
class Topic {
|
||||
//...
|
||||
}
|
||||
```
|
||||
|
||||
3、无指定实体的表名，修改实体类名
|
||||
|
||||
指定数据库旧的表名，修改实体命名时，同时设置此参数为修改之前的值，CodeFirst才可以正确修改数据库表；否则将视为【创建新表】
|
||||
|
||||
```csharp
|
||||
[Table(OldName = "Topic")]
|
||||
class Topic2 {
|
||||
//...
|
||||
}
|
||||
```
|
||||
```sql
|
||||
ALTER TABLE `cccddd`.`Topic` RENAME TO `cccddd`.`Topic2`;
|
||||
```
|
||||
|
||||
4、修改属性的类型
|
||||
|
||||
把 Id 类型改为 uint 后
|
||||
```sql
|
||||
ALTER TABLE `cccddd`.`Topic2` MODIFY `Id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT;
|
||||
```
|
||||
```csharp
|
||||
[Column(DbType = "varchar(128)")]
|
||||
public string Title { get; set; }
|
||||
```
|
||||
```sql
|
||||
ALTER TABLE `cccddd`.`Topic2` MODIFY `Title2` VARCHAR(128);
|
||||
```
|
||||
|
||||
5、指定属性的字段名
|
||||
|
||||
这样指定后，修改实体的属性名不影响数据库对应的列
|
||||
```csharp
|
||||
[Column(Name = "titl2")]
|
||||
public string Title { get; set; }
|
||||
```
|
||||
|
||||
6、无指定属性的字段名，修改属性名
|
||||
|
||||
指定数据库旧的列名，修改实体属性命名时，同时设置此参数为修改之前的值，CodeFirst才可以正确修改数据库字段；否则将视为【新增字段】
|
||||
|
||||
```csharp
|
||||
[Column(OldName = "Title2")]
|
||||
public string Title { get; set; }
|
||||
```
|
||||
```sql
|
||||
ALTER TABLE `cccddd`.`Topic2` CHANGE COLUMN `Title2` `Title` VARCHAR(255);
|
||||
```
|
||||
|
||||
7、提供方法同步结构
|
||||
|
||||
```csharp
|
||||
var t2 = fsql.CodeFirst.SyncStructure<Topic>();
|
||||
//同步实体类型到数据库
|
||||
```

|

|
||||
```
|
||||
|
||||
### 获取所有数据库
|
||||
|
||||
```csharp
|
||||
var t1 = fsql.DbFirst.GetDatabases();
|
||||
//返回字符串数组, ["cccddd", "test"]
|
||||
```
|
||||
|
||||
### 获取指定数据库的表信息
|
||||
|
||||
```csharp
|
||||
var t2 = fsql.DbFirst.GetTablesByDatabase(fsql.DbFirst.GetDatabases()[0]);
|
||||
//返回包括表、列详情、主键、唯一键、索引、外键
|
||||
```

# 查询数据
|
||||
|
||||
## 测试代码
|
||||
|
||||
```csharp
|
||||
IFreeSql fsql = new FreeSql.FreeSqlBuilder()
|
||||
.UseConnectionString(FreeSql.DataType.MySql, "Data Source=127.0.0.1;Port=3306;User ID=root;Password=root;Initial Catalog=cccddd;Charset=utf8;SslMode=none;Max pool size=10")
|

|
||||
}
|
||||
```
|
||||
|
||||
# Where
|
||||
|
||||
### 表达式函数支持
|
||||
|
||||
#### String 对象方法
|
||||
StartsWith, EndsWith, Contains, ToLower, ToUpper, Substring, Length, IndexOf, PadLeft, PadRight, Trim, TrimStart, TrimEnd, Replace, CompareTo
|
||||
|
||||
#### Math 方法
|
||||
...
|
||||
|
||||
### 单表
|
||||
```csharp
|
||||
var sql = select.Where(a => a.Id == 10).ToSql();
|
||||
///SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a.`Title` as4, a.`CreateTime` as5 FROM `tb_topic` a WHERE (a.`Id` = 10)
|
||||
|
||||
sql = select.Where(a => a.Id == 10 && a.Id > 10 || a.Clicks > 100).ToSql();
|
||||
///SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a.`Title` as4, a.`CreateTime` as5 FROM `tb_topic` a WHERE (a.`Id` = 10 AND a.`Id` > 10 OR a.`Clicks` > 100)
|
||||
```
|
||||
|
||||
### 多表，使用导航属性
|
||||
```csharp
|
||||
sql = select.Where(a => a.Type.Name == "typeTitle" && a.Type.Guid == a.TestTypeInfoGuid).ToSql();
|
||||
///SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a__Type.`Guid` as4, a__Type.`ParentId` as5, a__Type.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a, `TestTypeInfo` a__Type WHERE (a__Type.`Name` = 'typeTitle' AND a__Type.`Guid` = a.`TestTypeInfoGuid`)
|
||||
|
||||
sql = select.Where(a => a.Type.Parent.Name == "tparent").ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a__Type.`Guid` as4, a__Type.`ParentId` as5, a__Type.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a, `TestTypeInfo` a__Type, `TestTypeParentInfo` a__Type__Parent WHERE (a__Type__Parent.`Name` = 'tparent')
|
||||
```
|
||||
|
||||
### 多表，没有导航属性
|
||||
```csharp
|
||||
sql = select.Where<TestTypeInfo>((a, b) => b.Guid == a.TestTypeInfoGuid && b.Name == "typeTitle").ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, b.`Guid` as4, b.`ParentId` as5, b.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a, `TestTypeInfo` b WHERE (b.`Guid` = a.`TestTypeInfoGuid` AND b.`Name` = 'typeTitle')
|
||||
|
||||
sql = select.Where<TestTypeInfo, TestTypeParentInfo>((a, b, c) => c.Name == "tparent").ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a.`Title` as4, a.`CreateTime` as5 FROM `tb_topic` a, `TestTypeParentInfo` c WHERE (c.`Name` = 'tparent')
|
||||
```
|
||||
|
||||
### 多表，任意查
|
||||
```csharp
|
||||
sql = select.From<TestTypeInfo, TestTypeParentInfo>((s, b, c) => s
|
||||
.Where(a => a.Id == 10 && c.Name == "xxx")
|
||||
.Where(a => b.ParentId == 20)).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, b.`Guid` as4, b.`ParentId` as5, b.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a, `TestTypeParentInfo` c, `TestTypeInfo` b WHERE (a.`Id` = 10 AND c.`Name` = 'xxx') AND (b.`ParentId` = 20)
|
||||
```
|
||||
|
||||
### 原生SQL
|
||||
```csharp
|
||||
sql = select.Where("a.clicks > 100 && a.id = ?id", new { id = 10 }).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a.`Title` as4, a.`CreateTime` as5 FROM `tb_topic` a WHERE (a.clicks > 100 && a.id = ?id)
|
||||
```
|
||||
|
||||
> 以上条件查询，支持 WhereIf
|
||||
|
||||
# 联表
|
||||
|
||||
### 使用导航属性联表
|
||||
```csharp
|
||||
sql = select.LeftJoin(a => a.Type.Guid == a.TestTypeInfoGuid).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a__Type.`Guid` as4, a__Type.`ParentId` as5, a__Type.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a LEFT JOIN `TestTypeInfo` a__Type ON a__Type.`Guid` = a.`TestTypeInfoGuid`
|
||||
|
||||
sql = select
|
||||
.LeftJoin(a => a.Type.Guid == a.TestTypeInfoGuid)
|
||||
.LeftJoin(a => a.Type.Parent.Id == a.Type.ParentId).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a__Type.`Guid` as4, a__Type.`ParentId` as5, a__Type.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a LEFT JOIN `TestTypeInfo` a__Type ON a__Type.`Guid` = a.`TestTypeInfoGuid` LEFT JOIN `TestTypeParentInfo` a__Type__Parent ON a__Type__Parent.`Id` = a__Type.`ParentId`
|
||||
```
|
||||
|
||||
### 没有导航属性联表
|
||||
```csharp
|
||||
sql = select.LeftJoin<TestTypeInfo>((a, b) => b.Guid == a.TestTypeInfoGuid).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, b.`Guid` as4, b.`ParentId` as5, b.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a LEFT JOIN `TestTypeInfo` b ON b.`Guid` = a.`TestTypeInfoGuid`
|
||||
|
||||
sql = select
|
||||
.LeftJoin<TestTypeInfo>((a, b) => b.Guid == a.TestTypeInfoGuid)
|
||||
.LeftJoin<TestTypeParentInfo>((a, c) => c.Id == a.Type.ParentId).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, b.`Guid` as4, b.`ParentId` as5, b.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a LEFT JOIN `TestTypeInfo` b ON b.`Guid` = a.`TestTypeInfoGuid` LEFT JOIN `TestTypeParentInfo` c ON c.`Id` = b.`ParentId`
|
||||
```
|
||||
|
||||
### 联表任意查
|
||||
```csharp
|
||||
sql = select.From<TestTypeInfo, TestTypeParentInfo>((s, b, c) => s
|
||||
.LeftJoin(a => a.TestTypeInfoGuid == b.Guid)
|
||||
.LeftJoin(a => b.ParentId == c.Id)).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, b.`Guid` as4, b.`ParentId` as5, b.`Name` as6, a.`Title` as7, a.`CreateTime` as8 FROM `tb_topic` a LEFT JOIN `TestTypeInfo` b ON a.`TestTypeInfoGuid` = b.`Guid` LEFT JOIN `TestTypeParentInfo` c ON b.`ParentId` = c.`Id`
|
||||
```
|
||||
|
||||
### 原生SQL联表
|
||||
```csharp
|
||||
sql = select.LeftJoin("TestTypeInfo b on b.Guid = a.TestTypeInfoGuid and b.Name = ?bname", new { bname = "xxx" }).ToSql();
|
||||
//SELECT a.`Id` as1, a.`Clicks` as2, a.`TestTypeInfoGuid` as3, a.`Title` as4, a.`CreateTime` as5 FROM `tb_topic` a LEFT JOIN TestTypeInfo b on b.Guid = a.TestTypeInfoGuid and b.Name = ?bname
|
||||
```
|
||||
|
||||
# 查询数据
|
||||
|
||||
### 返回 List
|
||||
```csharp
|
||||
List<Topic> t1 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList();
|
||||
```
|
||||
|
||||
### 返回 List + 导航属性的数据
|
||||
```csharp
|
||||
List<Topic> t2 = select.LeftJoin(a => a.Type.Guid == a.TestTypeInfoGuid).ToList();
|
||||
//此时会返回普通字段 + 导航对象 Type 的数据
|
||||
```
|
||||
|
||||
### 指定字段返回
|
||||
```csharp
|
||||
//返回一个字段
|
||||
List<int> t3 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList(a => a.Id);
|
||||
|
||||
//返回匿名类
|
||||
List<匿名类> t4 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList(a => new { a.Id, a.Title });
|
||||
|
||||
//返回元组
|
||||
List<(int, string)> t5 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList<(int, string)>("id, title");
|
||||
```
|
||||
|
||||
### 执行SQL返回数据
|
||||
```csharp
|
||||
class xxx {
|
||||
public int Id { get; set; }
|
||||
public string Path { get; set; }
|
||||
public string Title2 { get; set; }
|
||||
}
|
||||
|
||||
List<xxx> t6 = fsql.Ado.Query<xxx>("select * from song");
|
||||
List<(int, string ,string)> t7 = fsql.Ado.Query<(int, string, string)>("select * from song");
|
||||
List<dynamic> t8 = fsql.Ado.Query<dynamic>("select * from song");
|
||||
```

||||
### 列优先级
|
||||
|
||||
> 全部列 < 指定列(Set/SetRaw) < 忽略列(IgnoreColumns)
|
||||
|
||||
### 测试代码
|
||||
|
||||
```csharp
|
||||
[Table(Name = "tb_topic")]
|
||||
class Topic {
|
||||
[Column(IsIdentity = true, IsPrimary = true)]
|
||||
public int Id { get; set; }
|
||||
public int Clicks { get; set; }
|
||||
public TestTypeInfo Type { get; set; }
|
||||
public string Title { get; set; }
|
||||
public DateTime CreateTime { get; set; }
|
||||
}
|
||||
|
||||
IFreeSql fsql = new FreeSql.FreeSqlBuilder()
|
||||
.UseConnectionString(FreeSql.DataType.MySql, "Data Source=127.0.0.1;Port=3306;User ID=root;Password=root;Initial Catalog=cccddd;Charset=utf8;SslMode=none;Max pool size=10")
|
||||
.Build();
|
||||
IUpdate<Topic> update => fsql.Update<Topic>();
|
||||
```
|
||||
|
||||
### 动态条件
|
||||
```csharp
|
||||
Update<Topic>(object dywhere)
|
||||
```
|
||||
dywhere 支持
|
||||
|
||||
* 主键值
|
||||
* new[] { 主键值1, 主键值2 }
|
||||
* Topic对象
|
||||
* new[] { Topic对象1, Topic对象2 }
|
||||
* new { id = 1 }
|
||||
|
||||
### 更新指定列
|
||||
```csharp
|
||||
var t1 = fsql.Update<Topic>(1).Set(a => a.CreateTime, DateTime.Now).ToSql();
|
||||
//UPDATE `tb_topic` SET `CreateTime` = '2018-12-08 00:04:59' WHERE (`Id` = 1)
|
||||
```
|
||||
|
||||
### 更新指定列，累加
|
||||
```csharp
|
||||
var t2 = fsql.Update<Topic>(1).Set(a => a.Clicks + 1).ToSql();
|
||||
//UPDATE `tb_topic` SET `Clicks` = ifnull(`Clicks`,0) + 1 WHERE (`Id` = 1)
|
||||
```
|
||||
|
||||
### 保存实体
|
||||
```csharp
|
||||
var item = new Topic { Id = 1, Title = "newtitle" };
|
||||
var t3 = update.SetSource(item).ToSql();
|
||||
//UPDATE `tb_topic` SET `Clicks` = ?p_0, `Title` = ?p_1, `CreateTime` = ?p_2 WHERE (`Id` = 1)
|
||||
```
|
||||
|
||||
### 保存实体，忽略一些列
|
||||
```csharp
|
||||
var t4 = update.SetSource(item).IgnoreColumns(a => a.Clicks).ToSql();
|
||||
//UPDATE `tb_topic` SET `Title` = ?p_0, `CreateTime` = ?p_1 WHERE (`Id` = 1)
|
||||
var t5 = update.SetSource(item).IgnoreColumns(a => new { a.Clicks, a.CreateTime }).ToSql();
|
||||
//UPDATE `tb_topic` SET `Title` = ?p_0 WHERE (`Id` = 1)
|
||||
```
|
||||
|
||||
### 批量保存
|
||||
```csharp
|
||||
var items = new List<Topic>();
|
||||
for (var a = 0; a < 10; a++) items.Add(new Topic { Id = a + 1, Title = $"newtitle{a}", Clicks = a * 100 });
|
||||
|
||||
var t6 = update.SetSource(items).ToSql();
|
||||
//UPDATE `tb_topic` SET `Clicks` = CASE `Id` WHEN 1 THEN ?p_0 WHEN 2 THEN ?p_1 WHEN 3 THEN ?p_2 WHEN 4 THEN ?p_3 WHEN 5 THEN ?p_4 WHEN 6 THEN ?p_5 WHEN 7 THEN ?p_6 WHEN 8 THEN ?p_7 WHEN 9 THEN ?p_8 WHEN 10 THEN ?p_9 END, `Title` = CASE `Id` WHEN 1 THEN ?p_10 WHEN 2 THEN ?p_11 WHEN 3 THEN ?p_12 WHEN 4 THEN ?p_13 WHEN 5 THEN ?p_14 WHEN 6 THEN ?p_15 WHEN 7 THEN ?p_16 WHEN 8 THEN ?p_17 WHEN 9 THEN ?p_18 WHEN 10 THEN ?p_19 END, `CreateTime` = CASE `Id` WHEN 1 THEN ?p_20 WHEN 2 THEN ?p_21 WHEN 3 THEN ?p_22 WHEN 4 THEN ?p_23 WHEN 5 THEN ?p_24 WHEN 6 THEN ?p_25 WHEN 7 THEN ?p_26 WHEN 8 THEN ?p_27 WHEN 9 THEN ?p_28 WHEN 10 THEN ?p_29 END WHERE (`Id` IN (1,2,3,4,5,6,7,8,9,10))
|
||||
```
|
||||
|
||||
> 批量保存的场景，先查询20条记录，根据本地很复杂的规则把集合的值改完后
|
||||
|
||||
> 传统做法是循环20次保存，用 case when 只要一次就行
|
||||
|
||||
### 批量保存，忽略一些列
|
||||
```csharp
|
||||
var t7 = update.SetSource(items).IgnoreColumns(a => new { a.Clicks, a.CreateTime }).ToSql();
|
||||
//UPDATE `tb_topic` SET `Title` = CASE `Id` WHEN 1 THEN ?p_0 WHEN 2 THEN ?p_1 WHEN 3 THEN ?p_2 WHEN 4 THEN ?p_3 WHEN 5 THEN ?p_4 WHEN 6 THEN ?p_5 WHEN 7 THEN ?p_6 WHEN 8 THEN ?p_7 WHEN 9 THEN ?p_8 WHEN 10 THEN ?p_9 END WHERE (`Id` IN (1,2,3,4,5,6,7,8,9,10))
|
||||
```
|
||||
|
||||
### 批量更新指定列
|
||||
```csharp
|
||||
var t8 = update.SetSource(items).Set(a => a.CreateTime, DateTime.Now).ToSql();
|
||||
//UPDATE `tb_topic` SET `CreateTime` = ?p_0 WHERE (`Id` IN (1,2,3,4,5,6,7,8,9,10))
|
||||
```
|
||||
|
||||
> 指定列更新后，批量保存将失效
|
||||
|
||||
### 更新条件
|
||||
|
||||
> 除了顶上介绍的 dywhere 构造参数外，还支持 Where lambda/sql 方法
|
||||
|
||||
```csharp
|
||||
var t9 = update.Set(a => a.Title, "新标题").Where(a => a.Id == 1).ToSql();
|
||||
//UPDATE `tb_topic` SET `Title` = '新标题' WHERE (Id = 1)
|
||||
```
|
||||
|
||||
### 自定义SQL
|
||||
|
||||
```csharp
|
||||
var t10 = update.SetRaw("Title = {0}", "新标题").Where("Id = {0}", 1).ToSql();
|
||||
//UPDATE `tb_topic` SET Title = '新标题' WHERE (Id = 1)
|
||||
//sql语法条件，参数使用 {0}，与 string.Format 保持一致，无须加单引号，错误的用法：'{0}'
|
||||
```
|
||||
|
||||
### 执行命令
|
||||
|
||||
| 方法 | 返回值 | 参数 | 描述 |
|
||||
| - | - | - | - |
|
||||
| ExecuteAffrows | long | | 执行SQL语句，返回影响的行数 |
|
||||
| ExecuteUpdated | List\<T1\> | | 执行SQL语句，返回更新后的记录 |
