# Where
### 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

# 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> t5 = select.LeftJoin<TestTypeInfo>((a, b) => a.TypeGuid == b.Guid && b.Name == "111").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> t2 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList(a => a.Id);
//返回匿名类
List<匿名类> t3 = select.Where(a => a.Id > 0).Skip(100).Limit(200).ToList(a => new { a.Id, a.Title });
//返回元组
List<(int, string)> t4 = 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> t3 = fsql.Ado.Query<xxx>("select * from song");
