I got a problem, and after some hours of research I just want to die.
Is there a way to import lots of CSV data into one MySQL database but creating new tables with the file name of the CSV data?
Example: If I import data1.csv into db the table should be named data1 with all the data from data1.csv.
Thanks for your suggestions and answers.
There is no built in tool/method/command/query to accomplish what you desire within MySQL alone.
What will be required is 2 parts.
1st. of course your MySQL DB where the table will be created.
2nd. some 3rd party program that can interact with your DB. Eg. (Java, JavaScript, Python, even Unix shell scripting)
Following is a sudo example of what will be needed.
What this program will have to do is relatively simple.
It will require a couple inputs:
DataBase IP, Username, Password (these can be parameters passed into your program, or for simplicity of testing hard coded directly into the program)
The next input will be your file name. data1.csv
Using the inputs the program will harvest the 'data1' name as well as the first row of the data1.csv file to name each column.
Once the program collects this info, it can Connect to the DB and run the MySQL statement for CREATE TABLE TableName (RowName1 VARCHAR(255), RowName2 VARCHAR(255), ect...)
Finally it can do a MySQL command to import he *.csv file into the newly created table. eg.
LOAD DATA LOCAL INFILE 'C:/Stuff/csvFiles/Data1.csv'
INTO TABLE `SchemaName`.`Data1`
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
Hope this helps clear up your options an approach a little.
As part of automation we want to create MySQL DB script from Existing DB. Actually we can't use EF Code Firts migration because tables are more than 1000. So timeout error will come. So the alternative is generate script from existing db using MVC application.
If you can export your tables data to .csv comma separated value files, you can do a easy migration with LOAD DATA INFILE. My experience is not from db to db. Just from excel to MySQL db. I exported excel sheets as a somedata.csv files. And then I created a table that I need to and I use this scripts to import to MySQL database. I think you can use it.
LOAD DATA INFILE 'somedata.csv' INTO TABLE some_table
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n';
So, first you need to create your tables' structure again.
Second, you need to export your data to csv files.
Third, you can do import specific data by using LOAD DATA INFILE.
It is not the entire great way. But It can be fast enough. A table with more than 1 millions record will imported with just a minute. You can see
LOAD DATA INFILE documentation here
I'm a newbie here trying to import some data into my wordpress database (MySQL) and I wonder if any of you SQL experts out there can help?
Database type: MySQL
Table name: wp_loans
I would like to completely replace the data in table wp_loans with the contents of file xyz.csv located on a remote server, for example https://www.mystagingserver.com/xyz.csv
All existing data in the table should be replaced with the contents of the CSV file.
The 1st row of the CSV file is the table headings so can be ignored.
I'd also like to automate the script to run daily at say 01:00 in the morning if possible.
UPDATE
Here is the SQL I'm using to try and replace the table contents:
LOAD DATA INFILE 'https://www.mystagingserver.com/xyz.csv'
REPLACE
INTO TABLE wp_loans
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
IGNORE 1 LINES
I would recommend a cron job to automate the process, and probably use BCP (bulk copy) to insert the data into a table... But seeing as you are using MySQL, instead of BCP, try load data in file - https://mariadb.com/kb/en/load-data-infile/
I am new to Database. I have data in xls sheet and i want to insert that data into a table.
I have only one column data in xls sheet. The table is in MySQL database. Please help me how to do it.
Start the MySQL Command Prompt and enter
LOAD DATA LOCAL INFILE ‘C:\\path\\yourfile.csv’ INTO TABLE database.table FIELDS TERMINATED BY ‘;’ ENCLOSED BY ‘”‘ LINES TERMINATED BY ‘\r\n’ (field1, field2);
You can export it into a .csv file and then upload it: see this link
i believe excel has tools to connect directly with your mysql table as well, perhaps excel has built in tools to export as well?
Or you may want to try the recently released 'MySQL for Excel' module which is part of the 'MySQL Installer' package. It provides native utilities for importing and exporting data to/from MySQL tables right into Excel.
It is located here - http://dev.mysql.com/downloads/installer/
Can any one explain how to import a Microsoft Excel file in to a MySQL database?
For example, my Excel table looks like this:
Country | Amount | Qty
----------------------------------
America | 93 | 0.60
Greece | 9377 | 0.80
Australia | 9375 | 0.80
There's a simple online tool that can do this called sqlizer.io.
You upload an XLSX file to it, enter a sheet name and cell range, and it will generate a CREATE TABLE statement and a bunch of INSERT statements to import all your data into a MySQL database.
(Disclaimer: I help run SQLizer)
Below is another method to import spreadsheet data into a MySQL database that doesn't rely on any extra software. Let's assume you want to import your Excel table into the sales table of a MySQL database named mydatabase.
Select the relevant cells:
Paste into Mr. Data Converter and select the output as MySQL:
Change the table name and column definitions to fit your requirements in the generated output:
CREATE TABLE sales (
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
Country VARCHAR(255),
Amount INT,
Qty FLOAT
);
INSERT INTO sales
(Country,Amount,Qty)
VALUES
('America',93,0.60),
('Greece',9377,0.80),
('Australia',9375,0.80);
If you're using MySQL Workbench or already logged into mysql from the command line, then you can execute the generated SQL statements from step 3 directly. Otherwise, paste the code into a text file (e.g., import.sql) and execute this command from a Unix shell:
mysql mydatabase < import.sql
Other ways to import from a SQL file can be found in this Stack Overflow answer.
Export it into some text format. The easiest will probably be a tab-delimited version, but CSV can work as well.
Use the load data capability. See http://dev.mysql.com/doc/refman/5.1/en/load-data.html
Look half way down the page, as it will gives a good example for tab separated data:
FIELDS TERMINATED BY '\t' ENCLOSED BY '' ESCAPED BY '\'
Check your data. Sometimes quoting or escaping has problems, and you need to adjust your source, import command-- or it may just be easier to post-process via SQL.
There are actually several ways to import an excel file in to a MySQL database with varying degrees of complexity and success.
Excel2MySQL. Hands down, the easiest and fastest way to import Excel data into MySQL. It supports all verions of Excel and doesn't require Office install.
LOAD DATA INFILE: This popular option is perhaps the most technical and requires some understanding of MySQL command execution. You must manually create your table before loading and use appropriately sized VARCHAR field types. Therefore, your field data types are not optimized. LOAD DATA INFILE has trouble importing large files that exceed 'max_allowed_packet' size. Special attention is required to avoid problems importing special characters and foreign unicode characters. Here is a recent example I used to import a csv file named test.csv.
phpMyAdmin: Select your database first, then select the Import tab. phpMyAdmin will automatically create your table and size your VARCHAR fields, but it won't optimize the field types. phpMyAdmin has trouble importing large files that exceed 'max_allowed_packet' size.
MySQL for Excel: This is a free Excel Add-in from Oracle. This option is a bit tedious because it uses a wizard and the import is slow and buggy with large files, but this may be a good option for small files with VARCHAR data. Fields are not optimized.
Not sure if you have all this setup, but for me I am using PHP and MYSQL. So I use a PHP class PHPExcel. This takes a file in nearly any format, xls, xlsx, cvs,... and then lets you read and / or insert.
So what I wind up doing is loading the excel in to a phpexcel object and then loop through all the rows. Based on what I want, I write a simple SQL insert command to insert the data in the excel file into my table.
On the front end it is a little work, but its just a matter of tweaking some of the existing code examples. But when you have it dialed in making changes to the import is simple and fast.
the best and easiest way is to use "MySQL for Excel" app that is a free app from oracle. this app added a plugin to excel to export and import data to mysql. you can download that from here
When using text files to import data, I had problems with quotes and how Excel was formatting numbers. For example, my Excel configuration used the comma as decimal separator instead of the dot.
Now I use Microsoft Access 2010 to open my MySql table as linked table. There I can simply copy and paste cells from Excel to Access.
To do this, first install the MySql ODBC driver and create an ODBC connection.
Then in access, in the "External Data" tab, open "ODBC Database" dialog and link to any table using the ODBC connection.
Using MySql Workbench, you can also copy and paste your Excel data into the result grid of MySql Workbench. I gave detailed instructions in this answer.
Fastest and simpliest way is to save XLS as ODS (open document spreasheet) and import it from PhpMyAdmin

You could use DocChow, a very intuitive GIU for importing Excel into MySQL, and it's free on most common platforms (including Linux).
More especially if you are concerned about date, datetime datatypes, DocChow easily handles datatypes. If you are working with multiple Excel spreadsheets that you want to import into one MySQL table DocChow does the dirty work.
Step 1 Create Your CSV file
Step 2 log in to your mysql server
mysql -uroot -pyourpassword
Step 3
load your csv file
load data local infile '//home/my-sys/my-excel.csv' into table my_tables fields terminated by ',' enclosed by '"' (Country, Amount,Qty);
Another useful tool, and as a MySQL front-end replacement, is Toad for MySQL. Sadly, no longer supported by Quest, but a brilliant IDE for MySQL, with IMPORT and EXPORT wizards, catering for most file types.
If you are using Toad for MySQL steps to import a file is as follows:
create a table in MySQL with the same columns that of the file to be imported.
now the table is created, goto > Tools > Import > Import Wizard
now in the import wizard dialogue box, click Next.
click Add File, browse and select the file to be imported.
choose the correct dilimination.("," seperated for .csv file)
click Next, check if the mapping is done properly.
click Next, select the "A single existing table" radio button also select the table that to be mapped from the dropdown menu of Tables.
Click next and finish the process.
If you don't like plugins, VBA and external tools, I have an excel file that using formulas only allows you to create INSERT/UPDATES. You only have to put the data on the cells:
As an extra, there's another tab in the file to CREATE TABLES:
The file can be found on the following link:
EXCEL FILE
I've had good results with the Tools / Import CSV File feature in HeidiSQL, with CSV files directly exported from Excel 2019 with "Save As..."
It uses LOAD DATA INFILE internally but with a GUI interface and also analyzes the CSV file before passing it to LOAD DATA INFILE so it can, for example, create the table using the first row as column names and guessing the column data type (<New table> option as shown in the picture)
