使用SqlBulkCopy类结合DataTable类快速完成对目标为SQLSERVER的数据交换

 

Microsoft SQL Server 提供一个称为 bcp 的流行的命令提示符实用工具，用于将数据从一个表移动到另一个表（表既可以在同一个服务器上，也可以在不同服务器上）。SqlBulkCopy 类允许编写提供类似功能的托管代码解决方案。还有其他将数据加载到 SQL Server 表的方法（例如 INSERT 语句），但相比之下 SqlBulkCopy 提供明显的性能优势。

使用 SqlBulkCopy 类只能向 SQL Server 表写入数据。但是，数据源不限于 SQL Server；可以使用任何数据源，只要数据可加载到 DataTable 实例或可使用 IDataReader 实例读取数据。

  

需求

需要完成一个多张表的数据交换，源数据库为oracle，目标为SqlServer。

源表分几个业务块，每一块有多张表，其中一张主表，其余若干子表。

主表主键和子表关联外键为字符型，据查是GUID字符串。

目标表业务模块基本一致。

主表主键和子表关联外键为数字型，据查是INT32类型。

分析

源和目标表的数据内容基本相似，最大区别为主键不一致，导致源表主键无法放入目标表，目标每条记录的主键必须重新赋值。

源表和目标表一些不一致的字段类型，比如date到varchar(8)，varchar2(1)到bit等。

解决方法

由于SqlBulkCopy类能够批量插入数据到SqlServer，故采用该类作为数据交换。

源主到目标主表时，目标主键需要动态生成，同时目标子表的外键也需和主表主键对应。

思路如下：

先取得主表数据，然后生成DataTable类，附加一列动态生成目标主键列（轮询所有行，值从1到该DataTable的行数）。执行主表数据的插入。

依次取得子表所有数据DataTable，每张子表先增加一列，轮询所有行，按源外键关联主表DataTable找到动态生成的目标主键列，赋值给增加的那列。对新生成的子表DataTable依次插入目标子表。

源码

配置文件：

主表的标志，子表的标志，源表和目标表的各个字段的映射等都保存在配置文件中。

备注

使用SqlBulkCopy 类，配置映射时，目标表各个字段的名称必须和数据库中的字段名称保持大小写一致。

各个数据类型的转换的时候，必须在映射的DataTable已经转换好，最好是查询的SQL语句，已经转换好，相见配置文件。

插入的时候，目标表不能有重复主键，否则失败；每条记录的每个字段的实际值大小不能超过目标表，否则报错。
