關(guān)于COPY FROM STDIN導(dǎo)入數(shù)據(jù) 這種方式適合數(shù)據(jù)寫入量不太大， 并發(fā)度不太高的場景。 用戶可以使用以下方式通過COPY FROM STDIN語句直接向DWS寫入數(shù)據(jù)。 通過鍵盤輸入向DWS寫入數(shù)據(jù)。 通過JDBC驅(qū)動的CopyManager接口從文件或者數(shù)據(jù)庫向DWS來自：幫助中心PROMPT3 當(dāng)執(zhí)行COPY命令，并期望在終端輸入數(shù)據(jù)時（例如，COPY FROM STDIN），顯示提示符。 使用變量PROMPT3顯示COPY提示符： openGauss=# \set PROMPT3 '>>>>' openGauss=# copy HR.areaS from STDIN;來自：專題

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語句COPY不同，該命令讀取/寫入的文件只能是gsql客戶端所在機器上的本地文件。 操作簡單，適用于小批量數(shù)據(jù)入庫。 使用COPY FROM STDIN導(dǎo)入數(shù)據(jù) 其他文件或數(shù)據(jù)庫 使用Java語來自：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類簡介 父主題： 導(dǎo)入數(shù)據(jù)來自：幫助中心
