PostgreSQL csv从MySQL csv导出导入？

Question

它会工作吗？

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：由于某种原因

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

有缺失列。所以我认为分隔符有问题。我是否正确，我该怎么办？我可以检查下面的原因错误的行。但我必须寻找哪些角色？ PostgreSQL中

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

Answer 1

1. 正如@knitti的Postgres提到需要知道转义字符：ESCAPE '\'
2. OPTIONALLY ENCLOSED BY '“' 是CSV格式错误这是更好地强制引用
。

全码：

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; 

级

的Postgres 9.0.3：

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

Answer 2

默认引号字符是双引号，但是the documentation说，你可以用任何一个单字节字符。尝试添加

ESCAPE '\\'
