问题
I'm trying to load csv files into mysql table. Delimiter : ,(comma)
As part of the source data few of the field values are enclosed in double quotes and inside the double quotes we have , There are few records for which / is part of the field data and we need to escape it.
By default / is getting escaped and when I specified the " as escape character " is getting escaped. As we have multiple special characters inside the same file, we need to escape multiple special characters.
Any suggestion
Eg:
id name location
1 A "Location , name here"
2 B "Different Location"
3 C Another Location
4 D Location / with escape character
LOAD DATA LOCAL INFILE 'data.csv' INTO TABLE table_name FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 LINES;
回答1:
I think it's not possible. Referring to LOAD DATA reference
Any of the field- or line-handling options can specify an empty string (''). If not empty, the FIELDS [OPTIONALLY] ENCLOSED BY and FIELDS ESCAPED BY values must be a single character.
Only a single char is supported for ESCAPED BY field. My proposal is to use any programming language (e.g. PHP, C# etc.) for opening and processing file line-by-line using regexp
