这几天接到一个需求需要吧不同系统的数据库进行同步，需要我做一个中间平台进行连接，瞬间就想到了触发器调用接口然后通过API进行传递再写入另一个数据库。
sqlServer触发器调用JavaWeb接口
1、开启 Ole Automation Procedures
sqlServer要想调用web接口，就要使用自带的存储过程。而这些存储过程2005版本以后默认时关闭的，所以要先开启。
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
RECONFIGURE;
GO
EXEC sp_configure 'Ole Automation Procedures';
GO
关闭 Ole Automation Procedures
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
RECONFIGURE;
GO
EXEC sp_configure 'Ole Automation Procedures';
GO关闭高级选项
sp_configure 'show advanced options', 0;
GO
RECONFIGURE;
GO
然后就可以进行写触发器，因为我这边表的内容比较多，大家直接看代码就好了。

'MS_Description', N'称重信息表插入后触发器',
'SCHEMA', N'dbo',
'TABLE', N'称重信息',
'TRIGGER', N'kingdee'看着复杂其实一点也不复杂，因为这个数据库的表是中文（不是我建的表系统中的中文的我没办法改），大致就是获取插入的数据然后进行触发，请求，然后API执行插入另一个数据库。
然后执行插入语句就可以看到执行的结果了~
