如何在將表格導入MySQL時在CSV值內轉義逗號？

Question

我想將一個CSV文件導入到MySQL數據庫表中。 CSV行如下所示：

"00602"," ","42042","15590","0","0","0","35","9","67","1978","20608","21434","3.1","54700","11384","31.3","30.4","32","18.382809","-67.186759","0","PR","Puerto Rico","U","","787","AGUADA","URB SAN CRISTOBAL","AGUADA","003","72","4","N","0060","","","10380","","Metro","Aguadilla-Isabela-San Sebastián PR","Aguadilla PR MSA","","","","N","0","0","0","0","","0","0","0","0","0","322569","0","","","5456","415","9577","V17136"," "," ","","" 
"00602"," ","42042","15590","0","0","0","35","9","67","1978","20608","21434","3.1","54700","11384","31.3","30.4","32","18.382809","-67.186759","0","PR","Puerto Rico","U","","787","AGUADA","COMUNIDAD LAS FLORES","AGUADA","003","72","4","N","0060","","","10380","","Metro","Aguadilla-Isabela-San Sebastián PR","Aguadilla PR MSA","","","","N","0","0","0","0","","0","0","0","0","0","322569","0","","","5456","415","9577","V17136"," "," ","","" 

etc... 

正如您所看到的，這些字段用雙引號引起來，並用逗號分隔。然而，一些行有像這樣的數值內逗號（注意最後一個值）：

"00501"," ","0","0","0","0","0","0","0","0","0","0","0","0","0","0","0","0","0","40.81518","-73.0455","25","NY","New York","N","","631","HOLTSVILLE","I R S SERVICE CENTER","SUFFOLK","103","36","5","Y","5602","5380","408","35620","35004","Metro","New York-Northern New Jersey-Long Island NY-NJ-PA","New York-Northern New Jersey-Long Island","Nassau-Suffolk, NY PMSA","Northeast","Middle Atlantic","N","7","0","0","0","B","0","0","0","0","0","18640775","2807500","","","0","1","1","V13916","U"," ","New York-Newark-Bridgeport, NY-NJ-CT-PA","Nassau-Suffolk, NY" 

這是我的import語句看起來像：

LOAD DATA INFILE '/file.csv' 
REPLACE INTO TABLE zipcodes 
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' 
LINES TERMINATED BY '\n'; 

但預期它不工作。例如，第一插入的行與下述值的列：

Nassau-Suffolk, NY""00501 

代替它應該是：

Nassau-Suffolk, NY 

和00501應該被插入作爲下一行的第一列的值。

如何調整我的SQL以正常工作？

Answer 1

從MySQL Reference Manual，使用下面的選項，而不是：

LOAD DATA INFILE 'data.txt' INTO TABLE tbl_name 
    FIELDS TERMINATED BY ',' ENCLOSED BY '"' 
    LINES TERMINATED BY '\r\n' 

更新，以符合您的使用，但重要的部分是從OPTIONALLY ENCLOSED BY降OPTIONALLY。
