从MySQL csv导出导入PostgreSQL csv？

Question

它会起作用吗？

MySQL导出:

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

PostgreSQL的:

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

由于某种原因缺少列.所以我相信分隔符存在问题.我纠正了,我该怎么办？我可以检查以下原因错误的行.但我必须寻找哪些角色？

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

Answer 1

1. 正如@knitti提到的postgres需要知道转义字符:ESCAPE'\'
2. 选择性地封装'''是csv的不良格式.最好强制引用.

完整代码:

mysql 5.5.15:

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

postgres 9.0.3:

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