Title
Body
I have an unnormalized events-diary CSV from a client that I'm trying to load into a MySQL table so that I can refactor into a sane format. I created a table called 'CSVImport' that has one field for every column of the CSV file. The CSV contains 99 columns , so this was a hard enough task in itself: CREATE TABLE 'CSVImport' (id INT); ALTER TABLE CSVImport ADD COLUMN Title VARCHAR(256); ALTER TABLE CSVImport ADD COLUMN Company VARCHAR(256); ALTER TABLE CSVImport ADD COLUMN NumTickets VARCHAR(256); ... ALTER TABLE CSVImport Date49 ADD COLUMN Date49 VARCHAR(256); ALTER TABLE CSVImport Date50 ADD COLUMN Date50 VARCHAR(256); No constraints are on the table, and all the fields hold VARCHAR(256) values, except the columns which contain counts (represented by INT), yes/no (represented by BIT), prices (represented by DECIMAL), and text blurbs (represented by TEXT). I tried to load data into the file: LOAD DATA INFILE '/home/paul/clientdata.csv' INTO TABLE CSVImport; Query OK, 2023 rows affected, 65535 warnings (0.08 sec) Records: 2023 Deleted: 0 Skipped: 0 Warnings: 198256 SELECT * FROM CSVImport; | NULL | NULL | NULL | NULL | NULL | ... The whole table is filled with NULL . I think the problem is that the text blurbs contain more than one line, and MySQL is parsing the file as if each new line would correspond to one databazse row. I can load the file into OpenOffice without a problem. The clientdata.csv file contains 2593 lines, and 570 records. The first line contains column names. I think it is comma delimited, and text is apparently delimited with doublequote. UPDATE: When in doubt, read the manual: http://dev.mysql.com/doc/refman/5.0/en/load-data.html I added some information to the LOAD DATA stat
