I am working with a large database 1.5 gig in size and hundreds of tables / fields. I need to convert all tables into CSV files. PhpMyAdmin does not do this easily / times out.
I would rather use a shell / mysql command or a script to get the data out and into CSV.
Note:
I am looking to export ALL tables of the database - in 1 shot. I can not produce an export command for every single table individually.
You can use mysqldump:
The mysqldump command can also generate output in CSV, other delimited text, or XML format.
In particular, look at the following arguments:
--tab=path
--fields-[optionally-]enclosed-by
--fields-escaped-by
--fields-terminated-by
--lines-terminated-by
--no-create-info
You will need to do this table by table, see below.
SELECT *
INTO OUTFILE '/tmp/products.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM products
Note that the directory must be writable by the MySQL database server. If it's not, you'll get an error message like this:
#1 - Can't create/write to file '/tmp/products.csv' (Errcode: 13)
Also note that it will not overwrite the file if it already exists, instead showing this error message:
#1086 - File '/tmp/products.csv' already exists

Information about the software : sql2csv
Download link exe : http://www.convert-in.com/demos/sql2csv.exe
This is best option I found around for windows. With the software we can connect to local and remote DB server and select schema. In one shot we can extract all tables data into Valid CSV files.

After trying for a full day, I'm hoping someone here can help me make below script work. I've combined information from multiple threads (example) and websites, but can't get it to work.
What I'm trying to do:
I'm trying to get a MariaDB10 database called 'stock_db' on my Synology NAS to load all *.csv files from a specific folder (where I save downloaded historical prices of stocks) and add these to a table called 'prices'. The files are all equally named "price_history_'isin'.csv".
Below SQL statement works when running it individually from HeidiSQL on my Windows machine:
Working SQL
LOAD DATA LOW_PRIORITY LOCAL INFILE 'D:\\Downloads\\price_history_NL0010366407.csv'
IGNORE INTO TABLE `stock_db`.`prices`
CHARACTER SET utf8
FIELDS TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 2 LINES
(#vdate, #vprice)
SET
isin = 'NL0010366407',
date = STR_TO_DATE(#vdate, '%d-%m-%Y'),
price = #vprice
;
The issue
Unfortunately, when I try to batch loading all csv's from a folder on my NAS through below script, I keep getting the same error.
#!/bin/bash
for filename in ./price_history/*.csv; do
echo $filename
isin=${filename:30:12}
echo $isin
/volume1/#appstore/MariaDB10/usr/local/mariadb10/bin/mysql -u root -p \
"LOAD DATA LOW_PRIORITY LOCAL INFILE '$filename'\
IGNORE INTO TABLE 'stock_db.prices'\
CHARACTER SET utf8\
FIELDS TERMINATED BY ';'\
OPTIONALLY ENCLOSED BY '"'"'"'\
ESCAPED BY '"'"'"'\
LINES TERMINATED BY '\r\n'\
IGNORE 2 LINES (#vdate, #vprice)\
SET\
isin = '$isin',\
date = STR_TO_DATE(#vdate, '%d-%m-%Y'),\
price = #vprice;"
done
ERROR 1102 (42000): Incorrect database name
What I've tried
Took the database name out of stock_db.prices and mentioned it separately as [database] outside of the quoted SQL statement - Doesn't work
Changed quotes around 'stock_db.prices' in many different ways - Doesn't work
Separated the SQL into a separate file and referenced it '< stmt.sql' - Complicates things even further and couldn't get it to work at all (although probably preferred)
Considered (or even preferred) using a PREPARE statement, but seems I can't use this in combination with LOAD DATA (reference)
Bonus Question
If someone can help me do this without having to re-enter the user's password or putting the password in the script, this would be really nice bonus!
Update
Got the 'Incorrect Database Error' resolved by adding '-e' option
Now I have a new error on the csv files:
ERROR 13 "Permission Denied"
While the folder and files are full access for everyone.
Anyone any thoughts to this?
Thanks a lot!
Try to set database using -D option: change the first line to
/volume1/#appstore/MariaDB10/usr/local/mariadb10/bin/mysql -D stock_db -u root -p \ ...
You may have an error in this line IGNORE INTO TABLE 'stock_db.prices'\ - try to remove the single quotes.
Create file .my.cnf in your user's home directory and put the following information into it:
[client]
password="my password"
Info about option files.
'stock_db.prices'
Incorrect quoting. This will work since neither are keywords:
stock_db.prices
This will also work:
`stock_db`.`prices`
Note that the db name and the table name are quoted separately, using backtics.
I can't predict what will happen with this nightmare:
'"'"'"'
Hey I have a large database where customers request data that is specific to them. They usually send me the requests in a text or csv file. I was wondering if there is a way to get sql to read that file and take the content and put them into a sql query. This way I don't have to open up that file and copy and paste everything into a sql query.
Steve already answered it.
Let me add few words only.
you can not use the csv, text,excel or anyother format directly in
query for DML/DDL.. you can use file directly only for export/import.
No. MySQL is not designed to do this.
You need an intermediate script that can interpret the files and generate the queries you require.
Yes there is a way to do it: you can import the csv file to your database and then join it with any query you want.
You can load the csv file with an SQL query such as:
LOAD DATA INFILE "/tmp/test.csv"
INTO TABLE test
COLUMNS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
You can use other ways to import the data, see: How to import CSV file to MySQL table.
I tried this SQL solution in Ubuntu 14.04 with MySQL 5.6. For this to work you will have to put the test.csv file in the /tmp directory and do a chmod 755 test.csv for it to work. Otherwise MySQL is gives "Permission denied" errors. More about this issue on: LOAD DATA INFILE Error Code : 13
Inside a directory /mylog/ I have a bunch of CSV files. Each CSV file only has one line of data. I need this data to be inputted into a MySQL Database.
An example of a line would be:
2015-08-14 00:00:00,HOSTNAME,10271kB,17182kB,92874kB,10%,/dev/disk1,/
I need to remove the 'kB' from each file size and remove the % from the percentage field. I also need to make sure that the date time and hostname are always unique and no duplicate entries are ever put in.
This is what I started to write so far. But I'm obviously missing the database name to use and removing the kB and %. If there's anything else wrong or missing, let me know. There's also the fact mysql is called each time, is there a way to do multiple load data?
Shell script:
#!/bin/bash
for f in /var/log/mylog/*.csv
do
mysql -e "load data local infile '"$f"' into table myTable fields TERMINATED BY ',' LINES TERMINATED BY '\n'" -u myUser --password=myPassword --local-infile
done
I have read many postings and done numerous google searches with different key words to find the answer to this question. While there are many postings on the topic, none of the postings gives an answer that works on my machine, so I am creating a new posting.
I have MySQL 5.6 installed on a windows development machine that is not connected to a network. I am trying to export data from a table into an outfile which I can then use for other purposes. the query runs successfully. In fact, when I try to run the same query a second time, I get a message saying that the outfile already exists. But when I go hunting for the file by its name, or using windows explorer, I cannot find it.
WHERE IS THE OUTFILE IN WINDOWS 7, USING MYSQL 5.6?
Here is code to create the outfile:
SELECT * INTO OUTFILE 'table.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM table
Use the following syntax :
- you tell him where to put it !
SELECT * INTO OUTFILE 'c:/table.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM table
It normally stored in the DATA_DIR parameter location.
From the reference manual for the SELECT statement:
SELECT ... INTO OUTFILE is the complement of LOAD DATA INFILE.
From the reference manual for the LOAD DATA INFILE:
The server uses the following rules to locate the file:
If the file name is an absolute path name, the server uses it as given.
If the file name is a relative path name with one or more leading components, the server searches for the file relative to the server's data directory.
If a file name with no leading components is given, the server looks for the file in the database directory of the default database.
So I would look in the default database directory. To find out which it is:
show variables like 'datadir';
You can, of course, define the location of the file specifying in your select... into outfile... sentence.
Also, if you have the MySQL installed in your cliente (or you are working on localhost), you can write something like this in the command line:
mysql [connection parameters] -e"select ..." > yourFile.txt
This will dump the result of your select statement into yourFile.txt in the current directory.
Hope this helps
I know that this is discussed a lot but I don't find solution of how to do that.
What I need is to import an excel file (xls/xlsx) to my database table. It is a button which does that and the command which is executed is like that:
string cmdText = "LOAD DATA INFILE 'importTest4MoreMore.csv' INTO TABLE management FIELDS TERMINATED BY ',';";
It works great. But I need to import excel file not CSV. As far as I know LOAD DATA command does not support binary files which xls is.
So what's the solution to that? Please help
Thanks a lot

.xls will never be importable directly into MySQL. it's a compound OLE file, which means its internal layout is not understandable by mere mortals (or even Bill Gates). .xlsx is basically just a .zip file which contains multiple .xml/xslt/etc. files. You can probably extract the relevant .xml that contains the actual spreadsheet data, but again - it's not likely to be in a format that's directly importable by MySQL's load infile.
The simplest solution is to export the .xls/xlsx to a .csv.
How to import 'xlsx' file into MySQL:
1/ Open your '.xlsx' file Office Excel and click on 'Save As' button from menu and select
'CSV (MS-DOS) (*.csv)'
from 'Save as type' list. Finally click 'Save' button.
2/ Copy or upload the .csv file into your installed MySQL server (a directory path like: '/root/someDirectory/' in Linux servers)
3/ Login to your database:
mysql -u root -pSomePassword
4/ Create and use destination database:
use db1
5/ Create a MySQL table in your destination database (e.g. 'db1') with columns like the ones of '.csv' file above.
6/ Execute the following command:
LOAD DATA INFILE '/root/someDirectory/file1.csv' INTO TABLE `Table1` FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES;
Please note that the option 'IGNORE 1 LINES' says MySQL to ignore the first line of '.csv' file. So, it is just for '.xlsx' files with 1 header column. You can remove this option.
You can load xls or xlsx files with Data Import tool (MS Excel or MS Excel 2007 format) in dbForge Studio for MySQL. This tool opens Excel files directly, COM interface is not used; and command line is supported.
