Unanswered: how to replace contents of one column in a mysql db from a text file
i am using phpMyAdmin - 22.214.171.124 and MySQL client version: 4.1.22 using the web interface of phpMyAdmin
i have a mysql db table with a column called added_on where the data in it was wiped out. i have the data for that column in a text file but i dont know how to place it in the mysql db online
i wish it were as easy as copying and pasting into excel for example, but this is a little different
i have been trying to use the import command at the web page, but the data is not getting into the column
i realize this is a very basic question, but i have no idea how to get the data back into that column
please do a SHOW CREATE TABLE for your table
also, what fields are available in the text file for matching up with the table?
you should import the text file into its own table, and do a SHOW CREATE TABLE on that one too
meanwhile, i've asked the moderators to move this thread to the mysql forum
This is the code when i created the contents of the affected table to a copy so as i figured out how to restore the added_on column i wouldnt mess up the original.
as far as the file that has the data, it is one column saved in a text file, with 119,000 rows, the exact same number as the table noted above. it is just a raw txt file. if it needs to be another sort of file i can convert it to suit
CREATE TABLE `accessmy_clone`.`files_to_notes_bu_rev` (
`notes_id` bigint( 20 ) NOT NULL default '0',
`files_id` int( 11 ) default NULL ,
`added_by` bigint( 20 ) default NULL ,
`added_on` int( 11 ) default NULL ,
`notes_category` int( 1 ) NOT NULL default '0',
PRIMARY KEY ( `notes_id` )
) ENGINE = MYISAM DEFAULT CHARSET = latin1;
INSERT INTO `accessmy_clone`.`files_to_notes_bu_rev`
FROM `accessmy_clone`.`files_to_notes` ;
thanks for the reply
um... your text file has only one column?
i'm afraid you're going to have to write some application code to do the update
you won't be able to process the updates with only sql
Moved thread to MySQL forum.
ok, so let's say i export all the data with all the columns, then replace the column with the missing data with the data it needs to have, and save it as a csv file, is there a way to import that into a new table or an existing one?
yes, that will work, you would import the csv using the LOAD DATA INFILE command
