这篇文章主要为大家展示了“SQLServer触发器怎么调用JavaWeb接口”,内容简而易懂,条理清晰,希望能够帮助大家解决疑惑,下面让小编带领大家一起研究并学习一下“SQLServer触发器怎么调用JavaWeb接口”这篇文章吧。
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;GORECONFIGURE;GOsp_configure 'Ole Automation Procedures', 1;GORECONFIGURE;GOEXEC sp_configure 'Ole Automation Procedures';GO
关闭 Ole Automation Procedures
sp_configure 'show advanced options', 1;GORECONFIGURE;GOsp_configure 'Ole Automation Procedures', 1;GORECONFIGURE;GOEXEC sp_configure 'Ole Automation Procedures';GO
关闭高级选项
sp_configure 'show advanced options', 0;GORECONFIGURE;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。
CREATE TRIGGER [dbo].[kingdee]ON [dbo].[称重信息]WITH EXECUTE AS CALLERFOR INSERTASBEGIN -- Type the SQL Here.DECLARE @fbillno int;DECLARE @carid varchar(4000);DECLARE @type varchar(4000);DECLARE @sendplace varchar(4000);DECLARE @consignee varchar(4000);DECLARE @material varchar(4000);DECLARE @specification varchar(4000);DECLARE @gw varchar(4000);DECLARE @tare varchar(4000);DECLARE @nw varchar(4000);DECLARE @kw varchar(4000); DECLARE @aw varchar(4000);DECLARE @price varchar(4000);DECLARE @money varchar(4000);DECLARE @zfxs varchar(4000);DECLARE @square varchar(4000);DECLARE @weighingcost varchar(4000);DECLARE @gwtime varchar(4000);DECLARE @taretime varchar(4000);declare @url varchar(4000);declare @object int;declare @responseText varchar(4000);SELECT @fbillno = (select 流水号 from inserted);SELECT @carid = (select 车号 from inserted);SELECT @type = (select 过磅类型 from inserted);SELECT @sendplace = (select 发货单位 from inserted);SELECT @consignee = (select 收货单位 from inserted);SELECT @material = (select 货名 from inserted);SELECT @specification = (select 规格 from inserted);SELECT @gw = (select 毛重 from inserted);SELECT @tare = (select 皮重 from inserted);SELECT @nw = (select 净重 from inserted);SELECT @kw = (select 扣重 from inserted);SELECT @aw = (select 实重 from inserted);SELECT @price = (select 单价 from inserted);SELECT @money = (select 金额 from inserted);SELECT @zfxs = (select 折方系数 from inserted);SELECT @square = (select 方量 from inserted);SELECT @weighingcost = (select 过磅费 from inserted);SELECT @gwtime = (select 毛重时间 from inserted);SELECT @taretime = (select 皮重时间 from inserted);SELECT @url = 'http://ip/saveweight/' + CONVERT(INT, @fbillno)+'/'+ CONVERT(VARCHAR, @carid)+'/'+ CONVERT(VARCHAR, @type)+'/'+ CONVERT(VARCHAR, @sendplace)+'/'+ CONVERT(VARCHAR, @consignee)+'/'+ CONVERT(VARCHAR, @material)+'/'+ CONVERT(VARCHAR, @specification)+'/'+ CONVERT(VARCHAR, @gw)+'/'+ CONVERT(VARCHAR, @tare)+'/'+ CONVERT(VARCHAR, @nw)+'/'+ CONVERT(VARCHAR, @kw)+'/'+ CONVERT(VARCHAR, @aw)+'/'+ CONVERT(VARCHAR, @price)+'/'+ CONVERT(VARCHAR, @money)+'/'+ CONVERT(VARCHAR, @zfxs)+'/'+ CONVERT(VARCHAR, @square)+'/'+ CONVERT(VARCHAR, @weighingcost)+'/'+ CONVERT(VARCHAR, @gwtime)+'/'+ CONVERT(VARCHAR, @taretime);print @url;-- insert into one (id, name) VALUES (@id, @url);exec sp_OACreate'MSXML2.XMLHTTP',@object outexec sp_OAMethod @object,'open',null,'get',@url,'false'exec sp_OAMethod @object,'send'exec sp_OAMethod @object,'responseText',@responseText output print @responseText exec sp_OADestroy @object SET NOCOUNT ON;ENDGOEXEC sp_addextendedproperty'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~
