Question & Answer :
I person an unnormalized occasions-diary CSV from a case that I’m making an attempt to burden into a MySQL array truthful that I tin refactor into a sane format. I created a array known as ‘CSVImport’ that has 1 tract for all file of the CSV record. The CSV comprises ninety nine columns , truthful this was a difficult adequate project successful itself:
Make Array 'CSVImport' (id INT); Change Array CSVImport Adhd File Rubric VARCHAR(256); Change Array CSVImport Adhd File Institution VARCHAR(256); Change Array CSVImport Adhd File NumTickets VARCHAR(256); ... Change Array CSVImport Date49 Adhd File Date49 VARCHAR(256); Change Array CSVImport Date50 Adhd File Date50 VARCHAR(256);
Nary constraints are connected the array, and each the fields clasp VARCHAR(256) values, but the columns which incorporate counts (represented by INT), sure/nary (represented by Spot), costs (represented by DECIMAL), and matter blurbs (represented by Matter).
I tried to burden information into the record:
Burden Information INFILE '/location/paul/clientdata.csv' INTO Array CSVImport; Question Fine, 2023 rows affected, 65535 warnings (zero.08 sec) Information: 2023 Deleted: zero Skipped: zero Warnings: 198256 Choice * FROM CSVImport; | NULL | NULL | NULL | NULL | NULL | ...
The entire array is crammed with NULL.
I deliberation the job is that the matter blurbs incorporate much than 1 formation, and MySQL is parsing the record arsenic if all fresh formation would correspond to 1 databazse line. I tin burden the record into OpenOffice with out a job.
The clientdata.csv record comprises 2593 traces, and 570 information. The archetypal formation accommodates file names. I deliberation it is comma delimited, and matter is seemingly delimited with doublequote.
Replace:
Once successful uncertainty, publication the handbook: http://dev.mysql.com/doc/refman/5.zero/en/burden-information.html
I added any accusation to the Burden Information message that OpenOffice was astute adequate to infer, and present it hundreds the accurate figure of information:
Burden Information INFILE "/location/paul/clientdata.csv" INTO Array CSVImport COLUMNS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '"' Traces TERMINATED BY '\n' Disregard 1 Strains;
However inactive location are tons of wholly NULL data, and no of the information that bought loaded appears to beryllium successful the correct spot.
Usage mysqlimport to burden a array into the database:
mysqlimport --disregard-strains=1 \ --fields-terminated-by=, \ --section -u base \ -p Database \ TableName.csv
I recovered it astatine http://chriseiffel.com/all the pieces-linux/however-to-import-a-ample-csv-record-to-mysql/
To brand the delimiter a tab, usage --fields-terminated-by='\t'
