mysqlimport

问题 I have been using mysqlimport without problems for a long time, now as mysql 5.7 added json data type support, I'm trying to use mysqlimport with rows containing json data. Here is an example of a row in csv file that will be imported using mysqlimport: column_A_value,column_B_value,[{"x":20,"y":"some name"}] Notice that the last column type is json. Now when using mysqlimport as the following: mysqlimport -u user -ppass -h localhost --columns='col_A,col_B,col_C' --local --fields-terminated

问题 I'm trying to move a database table to another server; the complication is that the machine currently running the table has little to no space left; so I'm looking for a solution that can work over the net. I have tried mysqldumping the database from the src machine and piping it into mysql at the dest; but my database has 48m rows and even when turning auto_commit off & trx_commit cmd to 2; I am getting some dog slow times. mysqldump -uuser -ppass --opt dbname dbtable | mysql -h remove

问题 I'm importing a legacy db to a new version of our program, and I'm wondering if there's a way to not import some columns/tables from the dump, and rename other tables/columns as i import them? I'm aware I could edit the dump file in theory, but that seems like a hack, and so far none of my editors can handle opening the 1.3 gb file (Yes, I've read the question about that on here. No, none of the answers worked for me so far.). Suggestions? 回答1: It's possible to not import some tables by

问题 I have a php script that parses XML files and creates a large SQL file that looks something like this: INSERT IGNORE INTO table(field1,field2,field3...) VALUES ("value1","value2",int1...), ("value1","value2",int1)...etc This file adds up to be over 20GB (I've tested on a 2.5GB file but it fails too). I've tried commands like: mysql -u root -p table_name < /var/www/bigfile.sql this works on smaller files, say around 50MB. but it doesn't work with a larger file. I tried: mysql> source /var/www

问题 I'm trying to figure out how to pipe output into mysqlimport without any luck. I have a huge file (~250 GB) that I want to pipe to mysqlimport after processing it. I don't want to create an intermediate file/table. I'm imagining something like this: cat genome.mpileup | nawk 'sub("^...","")' | mysqlimport -uuser -ppassword Database But obviously this isn't working. Any suggestions on how to accomplish this? 回答1: It doesn't look like mysqlimport can read from STDIN but you can perhaps

问题 I'm importing some data from a .txt file into a MySQL database table, using mysqlimport. It seems to import OK (no error messages) but looks very odd when displayed, and can't be searched as expected. Here are the details. The original text file is saved in UTF-8, with records that look (in a text editor) like this. The second field includes line breaks: WAR-16,52 ~~~~~ Lorem ipsum dolor sit. Lorem ipsum dolor sit. ~~~~~ ENDOFRECORD WAR-16,53~~~~~Lorem ipsum dolor sit. Lorem ipsum dolor sit.

问题 I am running mysqlimport to load data and am having an issue with empty values not being loaded as null. I am using mysql 5.7.23 Issue can be recreated by creating a file named mytable.psv, containing: code|date_a|date_b 1|2018-11-27|2018-11-27 2|2018-11-27| Then run the commands: mysql -u root -e "CREATE DATABASE mydb" mysql -u root -e "USE mydb; CREATE TABLE mytable (code varchar(15) NOT NULL, date_a date NOT NULL, date_b date);" mysqlimport --ignore-lines=1 --fields-terminated-by='|' -

问题 I'm trying to use mysqlimport to import text files to a mysql database. The problem is that the linux box I am importing the text files from will not have an installation of mysql and I am importing these files to a database on a different server. Does mysqlimport need to have a full installation of mysql to work? Can I just bring over the mysqlimport exe and some libraries? Cheers, Kaiser 回答1: Yes, you can use it standalone, among the options described here you can specify host to connect to
