C# Class FrameDAL.Dialect.BaseDialect

Author: Vincent Lau. 数据库方言类的基类，此类实现了一些通用的方法，通过此类获得的SQL具有跨数据的特性， 因为无法确定所使用的数据库，所以此类只能生成一些通用的SQL，若想针对不同的数据库进行 定制与优化，应写一个具体的方言类继承此类或直接实现IDialect接口。

public GetDeleteRelationsSql ( PropertyInfo manyToManyProp ) : string
manyToManyProp System.Reflection.PropertyInfo
return string

GetDeleteSql() public method

获得实体类对应的delete sql
type为null 该类没有添加Table特性，或者Table.Name属性为空或空白字符串
public GetDeleteSql ( Type type ) : string
type System.Type 实体类
return string

获得一条SQL，该SQL从数据库中查询最近一次插入操作生成的主键，此方法由子类实现
public abstract GetGeneratedKeySql ( string seqName ) : string
seqName string 生成主键的序列，如果此方法的实现不需要此参数，可忽略
return string

GetInsertSql() public method

获得实体类对应的表的insert sql
type为null 该类没有添加Table特性，或者Table.Name属性为空或空白字符串 该类中没有任何公开属性
public GetInsertSql ( Type type ) : string
type System.Type 实体类
return string

GetLoadColumnPropertySql() public method

public GetLoadColumnPropertySql ( PropertyInfo prop ) : string
prop System.Reflection.PropertyInfo
return string

GetLoadManyToManyPropertySql() public method
