成都創(chuàng)新互聯(lián)網(wǎng)站制作重慶分公司

oracle11gexpdp工具的query參數(shù)使用

實際生產中導數(shù)據(jù)時可能會需要導部分數(shù)據(jù)到測試庫上,expdp的query參數(shù)就可以完成這樣的需求。

創(chuàng)新互聯(lián)服務項目包括鹽津網(wǎng)站建設、鹽津網(wǎng)站制作、鹽津網(wǎng)頁制作以及鹽津網(wǎng)絡營銷策劃等。多年來,我們專注于互聯(lián)網(wǎng)行業(yè),利用自身積累的技術優(yōu)勢、行業(yè)經(jīng)驗、深度合作伙伴關系等,向廣大中小型企業(yè)、政府機構等提供互聯(lián)網(wǎng)行業(yè)的解決方案,鹽津網(wǎng)站推廣取得了明顯的社會效益與經(jīng)濟效益。目前,我們服務的客戶以成都為中心已經(jīng)輻射到鹽津省份的部分城市,未來相信會繼續(xù)擴大服務區(qū)域并繼續(xù)獲得客戶的支持與信任!
