適用于多套DWS集群之間的數(shù)據(jù)同步。 使用gsql元命令\COPY導(dǎo)入數(shù)據(jù) 本地文件 與直接使用SQL語(yǔ)句COPY不同，該命令讀取/寫(xiě)入的文件只能是gsql客戶端所在機(jī)器上的本地文件。 操作簡(jiǎn)單，適用于小批量數(shù)據(jù)入庫(kù)。 使用COPY FROM STDIN導(dǎo)入數(shù)據(jù) 其他文件或數(shù)據(jù)庫(kù) 使用Java語(yǔ)來(lái)自：專題使用COPY FROM STDIN導(dǎo)入數(shù)據(jù) 關(guān)于COPY FROM STDIN導(dǎo)入數(shù)據(jù) CopyManager類簡(jiǎn)介 父主題： 導(dǎo)入數(shù)據(jù)來(lái)自：幫助中心
