MySQL Workbench Import NULL from CSV - mysql

I can't for the life of me make MySQL Workbench import NULL for blank cells in a CSV.
I've tried:
blank
NULL
\N
Each with and without ""
How the does one signify a cell is 'null' inside a CSV file I want to import into MySQL via Workbench?

Since MySQL Workbench version 8.0.16 (released on 04/25/2019) there has been an additional option for uploading .csv file -- "null and NULL word as SQL keyword". When selecting this option as YES, the NULL expression without quotes in .csv file (,NULL, rather than ,"NULL",) will work for this purpose.

You can solve your problem by updating your workbench to the newest.

If you were trying to import a CSV into the model for creating insert scripts (where you won't get the same options described in the other answers), try the following:
\func NULL
You can also use this syntax to call functions like the following to insert the current date time when you forward engineer the model to the database:
\func CURRENT_TIMESTAMP

I suggest switching to Navicat for MySQL -- if only for the csv table import wizard. After repeated attempts to get the MySQLWorkbench Import Wizard to work for my CSV file, I gave up. I recalled using Navicat in an early project and it worked flawlessly. For this import, I was able to load my 15000+ row CSV with multiple null datetime values into my MySQL table without a problem.
Weird that MySQLWorkbench still hasn't solved this annoyance. But Navicat provides an easy alternative until they do.

MySQL now allow data to be imported by phpMyAdmin

I have just ended up creating Django website and now using phpMyAdmin I am importing large data sets in my mode. However, it appears that there is something wrong with the column values which I am trying to import via phpMyAdmin. I see the following error:
#1366 - Incorrect string value: '\x93Desig...' for column 'sku_description' at row 1
If it was one or two columns I could've manually fixed it. However, as I mentioned there is tons of data in there. What would be the most practical solution for this problem?
Nevermind. I solved it by changing the encoding in excel.
In Excel 2010, save file as CSV and before clicking save, click on Tools->Web Options->Encoding->Unicode(Utf8) and save it. Now import it into MySQL via phpMyAdmin.

Importing partial data into MySQL from CSV

I have a CSV that is a partial projection of an origin table. I have the same table structure in my DB.
I would like to import only those columns into my DB, given that no additional NOT NULL constraints are in place (I explicitly disabled some of them). I don't know how to import them.
I have tried the following: from MySQL Workbench, right click on table and then Edit table data, then on the screen I tried the "Import records from an external file" button, loaded the CSV file but I got the following error:
[Window Title]
MySQL Workbench
[Main Instruction]
Error importing recordset
[Content]
error calling Python module function SQLIDEUtils.importRecordsetDataFromFile
[OK]
The column names are the same as in the DB but these are partial (not all columns as DB). The table is currently empty.
What can I do to import the data into MySQL?
It turns out that is the error that tool gives for ANY problems importing CSV data. They have opened a bug for more descriptive error responses.
For me it turned out that it can not work with non-Windows line breaks. So if your file came from Unix/Linux or Mac it will not work. You can just open it in Excel though and re-save it as an MS-DOS CSV and then it works. Other things that can make it throw up are any use of ";".
Also the tool has NO column mapping options so you have to have your import file matched to the table setup perfectly. If you have columns mis-matched or data types mis-matched it will also throw-up.
I got the same question and error when I was importing a csv file into MAC Mysqlworkbench.
I restored my file as windows comma separated (.csv). This works for me.
Check do you have permissions to import (on insert), and if you import clearing old data check do you have permissions on delete.
If it won't help, create a new table with least restrictions which has absolutely identical columns as in CSV file, try to import to it. If ok - just update/insert into your target table
If it won't help, try to import on another database.
If it won't help, check CSV file - is all contents is ok? (may be it should try first)

PHPMyadmin import CSV creates new table

I am trying to import some data into a MySQL 5.5.31 table from a CSV file using PHPMyadmin 4.0.0.
When I try to import, the import "works" but it creates a new table rather than imports into the current table - the new table is assigned a sequential name by PHPMyadmin and, whilst the data is viewable, the data is not usable as the table does not contain a unique column.
Here is a screenshot of the settings I am using to import which also shows I am trying to import into the table:
And here is the result I get from PHPMyadmin:
Any idea why this is happening? I have tried searching for the "The following structures have either been created or altered" message but found nothing here and only a few things on Google but none of the Google responses were of any help.
Not allowed to comment on Madhura Jayaratne's reply, but - because people trying to import ODS will look at this thread - it is worth pointing out that it is only partly correct. CSV has been fixed but the same bug still exists for ODS in phpMyAdmin 4.0.5.
This is a bug in phpMyAdmin and it has been fixed since version 4.0.1. See 14 item under 4.0.1.0 (2013-05-14) section of the change log file. Upgrade to 4.0.1 or a version greater than that.
Instead of phpmyadmin try SqlYog .SqlYog is userfriendly.Just try it

MySQL Workbench Inserts

I am using MySQL Workbench 5.2.28 for designing my database schema. I need to insert default data into some tables which can be done using the "Inserts" tab. However, it seems like it only allows entering data manually, one row at a time. I have an OUTFILE with several hundred rows that I would like to insert.
Is this possible with MySQL Workbench? Would creating separate MySQL scripts for importing default data be a better approach?
I am now using separate sql scripts for inserting my data as there doesn't seem to be an easy way to add bulk inserts to MySQL workbench.
Generate CSV (quoted if you have comas in values) in Excel for example, then just copy/paste all rows into workbench via 'inserts' tab for each table in model.
Works with Workbench version 5.2.40.
In the MySQL Workbench Version 6.2 you will find a Import Button which alows you to Import Inserts from a CSV File with "," as delemiter.
You are right there is no way I know doing this automatically. The only thing you can do is to generate all your inserts scripts in a single time by doing a forward engeniering and then by copying the insert statements at the end of the generated script (You must check the option "Generate INSERT statements").

How to import an excel file in to a MySQL database

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)
