PostgreSQL csv從MySQL csv導出導入？

Question

它會工作嗎？

MySQL的出口：

SELECT * INTO OUTFILE 'C:/data.csv' 
FIELDS TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '"' 
ESCAPED BY '\\' 
LINES TERMINATED BY '\n' 
FROM table; 

PostgreSQL的：由於某種原因

COPY table FROM 'C:/data.csv' WITH DELIMITER AS '\t' NULL AS '\\N' CSV 

有缺失列。所以我認爲分隔符有問題。我是否正確，我該怎麼辦？我可以檢查下面的原因錯誤的行。但我必須尋找哪些角色？ PostgreSQL中

ERROR: missing data for column "Column21" 
CONTEXT: COPY table, line 88219: ... 

Answer 1

1. 正如@knitti的Postgres提到需要知道轉義字符：ESCAPE '\'
2. OPTIONALLY ENCLOSED BY '「' 是CSV格式錯誤這是更好地強制引用
。

全碼：

的MySQL 5.5.15：

SELECT * 
INTO OUTFILE 'C:/data.csv' 
FIELDS TERMINATED BY '\t' ENCLOSED BY '"' ESCAPED BY '\\' 
LINES TERMINATED BY '\n' 
FROM table; 

級

的Postgres 9.0.3：

COPY table FROM 'C:/data.csv' WITH DELIMITER AS '\t' NULL AS '\\N' ESCAPE E'\\' CSV 

Answer 2

默認引號字符是雙引號，但是the documentation說，你可以用任何一個單字節字符。嘗試添加

ESCAPE '\\'
