在SQL Server數(shù)據(jù)庫中,如果需要讓INSERT語句自動(dòng)生成,應(yīng)該采用何種方法呢?下面就將為您介紹自動(dòng)生成INSERT語句的SQL存儲(chǔ)過程,供您參考。

這是建立一個(gè)存儲(chǔ)過程,通過執(zhí)行這個(gè)存儲(chǔ)過程,將指定的數(shù)據(jù)表中的數(shù)據(jù)導(dǎo)成Insert語句形式
--這是一個(gè)可以將表中的數(shù)據(jù)自動(dòng)生成INSERT語句的存儲(chǔ)過程
--有個(gè)BUG,如果是自動(dòng)增長(zhǎng)列,數(shù)據(jù)也會(huì)被插入
--在查詢分析器中執(zhí)行完成后,可以從執(zhí)行結(jié)果中自制出SQL腳本。
