本文為您舉例了DB2數(shù)據(jù)庫(kù)從從Excel中讀取數(shù)據(jù)并導(dǎo)入，例子的功能有兩個(gè)：一是POI讀取Excel，二是DB2數(shù)據(jù)庫(kù)的連接和SQL執(zhí)行。供您參考，希望能對(duì)您有所啟迪。

您是否遇到過(guò)需要從Excel中讀取數(shù)據(jù)呢？將數(shù)據(jù)導(dǎo)入數(shù)據(jù)庫(kù)保存，最終可以用報(bào)表讀取數(shù)據(jù)庫(kù)并顯示，比較簡(jiǎn)單。查了一下兩者的資料，覺的也無(wú)所謂，需要的功能比較簡(jiǎn)單，只要能讀取Excel數(shù)據(jù)就行，***決定使用POI，比較信任apache,使用果然很簡(jiǎn)單，上網(wǎng)找了個(gè)源碼，Copy過(guò)來(lái)稍微改改就能用了。

下面附的代碼是一個(gè)Demo，功能有兩個(gè)：一是POI讀取Excel，二是DB2數(shù)據(jù)庫(kù)的連接和SQL執(zhí)行。
