SQLServer觸發(fā)器調(diào)用JavaWeb接口的過程詳解

更新時(shí)間：2021年12月30日 10:20:49 作者：coderxgc

sqlServer要想調(diào)用web接口，就要使用自帶的存儲(chǔ)過程。而這些存儲(chǔ)過程2005版本以后默認(rèn)時(shí)關(guān)閉的，所以要先開啟。對SQLServer觸發(fā)器調(diào)用JavaWeb接口的過程感興趣的朋友一起看看吧

這幾天接到一個(gè)需求需要吧不同系統(tǒng)的數(shù)據(jù)庫進(jìn)行同步，需要我做一個(gè)中間平臺(tái)進(jìn)行連接，瞬間就想到了觸發(fā)器調(diào)用接口然后通過API進(jìn)行傳遞再寫入另一個(gè)數(shù)據(jù)庫。

1、開啟 Ole Automation Procedures
sqlServer要想調(diào)用web接口，就要使用自帶的存儲(chǔ)過程。而這些存儲(chǔ)過程2005版本以后默認(rèn)時(shí)關(guān)閉的，所以要先開啟。

 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

關(guān)閉 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

關(guān)閉高級(jí)選項(xiàng)

sp_configure 'show advanced options', 0;
GO
RECONFIGURE;
GO

然后就可以進(jìn)行寫觸發(fā)器，因?yàn)槲疫@邊表的內(nèi)容比較多，大家直接看代碼就好了。

看著復(fù)雜其實(shí)一點(diǎn)也不復(fù)雜，因?yàn)檫@個(gè)數(shù)據(jù)庫的表是中文（不是我建的表系統(tǒng)中的中文的我沒辦法改），大致就是獲取插入的數(shù)據(jù)然后進(jìn)行觸發(fā)，請求，然后API執(zhí)行插入另一個(gè)數(shù)據(jù)庫。
然后執(zhí)行插入語句就可以看到執(zhí)行的結(jié)果了~
