I am unable to successfully import a csv file in the neo4j browser, as the nodes are created but they do not show the properties. Does anyone see the problem? I will describe how I proceeded:
This is how the csv file looks
I have tested the csv file with LOAD CSV WITH HEADERS FROM "file:///testCSV3.csv" AS line
WITH line LIMIT 4
RETURN line
and the result is ok (I guess?):
I then tried various things, as e.g. this query:
LOAD CSV WITH HEADERS FROM "file:///testCSV3.csv" AS line
CREATE (:Activity {activityName: line.MyActivity, time: toInteger(line.Timestamp)})
The outcome is nodes without properties:
Any ideas what I am missing? Why are the properties activityName and time not showing up? - Thanks in advance!
(You should have shown your raw CSV file, to make the problem clearer.)
I assume your raw file starts out like this:
ID ;Timestamp;MyActivity
1;1;Run
2;2;Talk
3;3;Eat
LOAD CSV is sensitive to extra spaces, so your ID header should not be followed by a space. Also, the default field terminator is a comma not a semicolon, so you need to specify the FIELDTERMINATOR option to override the default.
Your results would be more reasonable if you removed the extra space and changed your query to this:
LOAD CSV WITH HEADERS FROM "file:///testCSV3.csv" AS line FIELDTERMINATOR ';'
WITH line LIMIT 4
RETURN line

I am trying to figure out why MYSQL isn't working as expected.
I imported my data from a CSV into a table called Products, which is shown in the screenshot. It's a small table of just ID and Name.
But when I run the where clause, finding out where the Name = 'SMS', it returns nothing? I don't understand what the issue is.
My CSV contents in Notepad++ is shown below:
This is what I used to load in my CSV, if there are any errors here.
Could you share your csv file content?
It's happened to me too before, and the problem is because there's some blank space in the data in csv file.
So maybe you could parse first your csv file data (remove the "not needed" blank space) before import it to database
This is often caused by spaces or look-alike characters. If caused by spaces or invisible characters at the beginning/end, you can try:
where name like '%SMS%'
You can then make this more general:
where name like '%S%M%S%'
When you get a match, you'll need to do more investigate to find the actual cause.
I have a 13gb .txt file which I am importing into MySQL, however I don't want to import all of the data. For example there are many columns that are either completely empty or contain irrelevant information - I only want to import ~100/360 I've been provided. If I only create headers for the columns I want, can I select the specific corresponding data from the .txt file to be uploaded?
Normally I would use a text editor to remove the superfluous data, but I do not possess a text editor that can handle a file of this size.
You can ignore specific columns in the input file by assigning them to a user-defined variable instead of a database column.
For example if you had a CSV file with 4 columns and just wanted to import columns 1 and 4 into your table you could do something like this:
load data infile '/tmp/so42140337.csv'
into table so42140337
fields terminated by ','
lines terminated by '\n'
(c1,#dummy,#dummy,c2);
Given the size of your input file it may be more efficient to import it in chunks rather than importing the entire file in one command. You can use the pt-fifo-split tool for this, following the pattern in this blog post.
I have a large CSV file (nearly 10,000 rows) and I am trying to upload it on the BigQuery but it gives me this error:
ile-00000000: CSV table references column position 8, but line starting at position:622 contains only 8 columns. (error code: invalid)
Can anyone please tell me a possible to reason to it? I have double checked my Schema and it looks alright.
Thanks
I had this same issue when trying to import a large data set in a csv to a BigQuery table.
The issue turned out to be some ascii control characters (\b, \t, \r, \n) in the data that was written in the csv. When the csv was being sent to BigQuery these characters caused the BiqQuery csv parser to misinterpret the line and break because the data didn't match with the number of columns in the header.
Replacing these characters with a space (to preserve formatting as best as possible) allowed me to import the data without further issues.
The error message suggests that the load job failed because at least one row has fewer columns than the automatically detected schema dictates.
Add
allow_jagged_rows=true
in the options.
I am trying to load the following simple csv file into tableau public 9.3:
customers,item1,item2,item3,item4
1,0,0,0,0
2,0,0,0,0
3,0,0,0,0
However, it doesn't read the file as separate columns, despite the field separator being Comma. Instead it treats the whole line as one column. Any help would be greatly appreciated :
If you change your locale settings to English US you will be able to load the file. You should also be able to work around this by creating a schema.ini file.
Go to Data > Manage fields > [Field] Options
You can also control imported CSV behavior post import both by splitting individual columns (which will remain split on update as well), or by the image below at the CSV level.
That doesn`t work for me. So I reopen the .csv file in Excel and save it again in .csv format with ',' as the delimeter.
After that my file looks like .csv with ';' delimeter and works with Tableau.
I am importing some thousands lines of Data from a .txt file containing two columns and the format is as it follows:
A8041550408#=86^:|blablablablablablablablablablablablablablablablablablablabla1
blablablablablablablablablablablablablablablablablablablabla2
blablablablablablablablablablablablablablablablablablablabla3
A8041550408#=86^:|blablablablablablablablablablablablablablablablablablablabla1
blablablablablablablablablablablablablablablablablablablabla2
A8041550408#=86^:|blablablablablablablablablablablablablablablablablablablabla1
blablablablablablablablablablablablablablablablablablablabla2
blablablablablablablablablablablablablablablablablablablabla3
blablablablablablablablablablablablablablablablablablablabla4
etc....
What I have done so far is create a table with the two fields, but when i try to import the .txt file as a CSV and putting / Columns separated By : | /, I get an error:
"Invalid column count in CSV input on line 2."
Which is quite obvious since the second line of the .txt file is empty.
Moreover, I have tried importing the file as a CSV using LOAD DATA, and it didn't work as well it has just filled up the table with random words and phrases from the .txt file .
So my question is : How can I import the data from this file ?
You have to fix your file; in its current state you cannot expect the import module to be able to understand it. First step would be to remove the empty lines: How to remove blank lines from a Unix file
