We are writing some php to move data from a Microsoft SQL database to a MySQL database. The Microsoft data contains user input text, with line breaks and all sorts of wacky stuff
The process we've been working with is as follows:
select from a Microsoft SQL database into php array (works fine)
processes this into a .csv by looping the fputcsv() function:
fputcsv($delimiter = ',', $enclosure = '"', $escape_char = "\\");
(the .csv file looks good when I open it with google sheets)
upload the .csv file to the MySQL server with the following code:
LOAD DATA LOCAL INFILE 'c:/filename.csv'
INTO TABLE tablename
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS; ```
The problem is that when step 3 is executed, the resulting MySQL table is all jumbled up because it appears to get confused with the line breaks in the data, thinking it's a new line in the table.
I noticed the MySQL LOAD DATA command doesn't take the escape character as an argument, but I can't seem to find a way to give it to it. Is this the issue? How can we make this work?
I'm new here. I would like to ask question regarding with my codes. So my code is working perfectly but then after importing csv to mysql programmatically using LOAD INTO INFILE. I didn't know why my output kept getting this kind of format. Please see my codes below thanks!
$testing = $conn->prepare("LOAD DATA INFILE 'C:/xampp/mysql/data/mysql/usagetable.csv'
INTO TABLE trieinitialcountentry
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(Count_ID, InvItemLocID, OnHand, OnHandValue, StockCenter_ID)");
$testing->execute();
And also, some rows had been imported perfectly but some of them are not. Example of my output:
Count_ID InvItemLocID OnHand OnHandValue StockCenter_ID
737450 -2091889269 140.00 "2 788.80"
Apparently some of the values in the input CSV file are wrapped in quotes and you didn't pass this information to LOAD DATA INFILE.
Try this query:
$query = <<<'END'
LOAD DATA INFILE 'C:/xampp/mysql/data/mysql/usagetable.csv'
INTO TABLE trieinitialcountentry
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(Count_ID, InvItemLocID, OnHand, OnHandValue, StockCenter_ID)
END;
$testing = $conn->prepare($query);
$testing->execute();
Note the added OPTIONALLY ENCLOSED BY '"' clause.
I receive a csv file that looks fairly straightforward.
I run this on it and it tells me its ASCII.
echo mb_detect_encoding($fhandle , "auto");
However when i run my import code: It doesnt work correctly.
$sql= "LOAD DATA LOCAL INFILE '". $fhandle ."' INTO TABLE sys6_impBet FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 LINES
( AccNo_1,
MtgDate,
Code,
Venue,
Location,
Pool,
EventNo,
Gross_Sales,
Refunds,
Turnover,
Dividends,
Profit_Loss);" ;
It brings in the correct number of records but puts a NULL or 0 in every field / record.
So it is reading the file as it sees the records but won't get the values.
Heres a small sample:
AccNo_1,MtgDate,Code,Venue,Location,Pool,EventNo,Gross_Sales,Refunds,Turnover,Dividends,Profit_Loss
66096159,12/07/2015,Gallops,Penola,SA,Treble,0,279.00,0.00,279.00,"1,955.70","1,676.70"
66096159,12/07/2015,Gallops,Warrnambool,VIC,Treble,0,"1,048.00",0.00,"1,048.00","2,672.80","1,624.80"

66096718,12/07/2015,Gallops,Penola,SA,Win,6,204.00,0.00,204.00,"1,143.00",939.00

Is it an encoding problem.
IF I open the file in notepad and save as encoding UTF-8 and save it back down. Then the above code works and all is imported.
But I cant do that for every file every day??
Any ideas I can try?
I have tried this but no different:
$fhandle = mb_convert_encoding($fhandle, "UTF-8", "ASCII");
S
first check the internal encoding used by php
echo mb_internal_encoding();
then set it to required one
mb_internal_encoding("UTF-8");
I have a script that I am using to import .CSV data into a MySQL DB. The first field of data (email address) still has quote marks around it when I pull into MySQL. The other fields, the quotes are stripped out.
My CSV lines looks like this:
"email4#email.com"," Karla","Smith"
"email5#email.com"," Carl","Nichols"
The email addresses still have quotes in MySQL. The first and last name are fine.
Any suggestions?
<?php
$conn = mysql_connect('host','username','password');
mysql_select_db('db-name');
mysql_query("TRUNCATE TABLE contacts") or die(mysql_error());
mysql_query("LOAD DATA LOCAL INFILE 'New Member Weekly Report for Marketing.csv'
INTO TABLE contacts
Fields terminated by ',' ENCLOSED BY '\"'
LINES terminated by '\r'(
contact_email
,contact_first
,contact_last)")
or die("Import Error: " . mysql_error());
?>
On a little bit of googling, I found this:
Instead of writing a script to pull in information from a CSV file, you can link MYSQL directly to it and upload the information using the following SQL syntax.
To import an Excel file into MySQL, first export it as a CSV file. Remove the CSV headers from the generated CSV file along with empty data that Excel may have put at the end of the CSV file.
You can then import it into a MySQL table by running:
load data local infile 'uniq.csv' into table tblUniq fields terminated by ','
enclosed by '"'
lines terminated by '\n'
(uniqName, uniqCity, uniqComments)
The fields here are the actual tblUniq table fields that the data needs to sit in. The enclosed by and lines terminated by are optional and can help if you have columns enclosed with double-quotes such as Excel exports, etc.

I'm fairly new to php and CakePHP, and I'm trying to execute the following code after uploading a text file (2kb):
$filefullname = $this->request->data['File']['file']['tmp_name'];
debug($filefullname);
move_uploaded_file($filefullname, WWW_ROOT.'tmp.txt');
$query = 'LOAD DATA LOW_PRIORITY INFILE "'.WWW_ROOT.'tmp.txt'.'" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES';
debug($query);
$this->Agency->query($query);
Though the file can be found, I get the following output:
'C:\Windows\Temp\phpB413.tmp'
'LOAD DATA LOW_PRIORITY INFILE "C:\Data\myphpapplication\app\webroot\tmp.txt" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES'
Error: SQLSTATE[HY000]: General error: 29 File 'C:\Data\myphpapplication\app\webroot\tmp.txt' not found (Errcode: 13)
SQL Query: LOAD DATA LOW_PRIORITY INFILE "C:\Data\myphpapplication\app\webroot\tmp.txt" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES
How can I fix this?
Most likely the file is there, but MySQL doesn't allow you to read files from that location. MySQL is fairly restrictive from where it reads LOAD DATA ... INFILE, with good reasons. You may need to move your file first to a path that MySQL can read from, or change the settings for your MySQL server.
From the MySQL 5.1 manual:
Note that, in the non-LOCAL case, these rules mean that a file named
as ./myfile.txt is read from the server's data directory, whereas the
file named as myfile.txt is read from the database directory of the
default database. [...]
And:
Windows path names are specified using forward slashes rather than
backslashes. If you do use backslashes, you must double them.
#JvO is guiding you down the right path. I think you're missing a couple of important elements, one of which is moving the uploaded file from its initial temp directory on the server to a place where MySQL can officially read it (it won't read it from a temp directory for security reasons).
Here's an example from a project I did, which uploaded a CSV file and then MOVED it to a readable directory. I first uploaded it with the move_uploaded_file function, and then created a variable describing the uploaded path of the new file for use in a LOAD DATA query.
move_uploaded_file($_FILES["fCSV"]["tmp_name"],"user_uploads/SG".$dapID ."/". $_FILES["fCSV"]["name"]);
$csvfile = "user_uploads/SG".$dapID ."/". $_FILES["fCSV"]["name"];
In your LOAD DATA query, you're missing the "LOCAL" keyword, which tells MySQL to read the file from a specified directory, otherwise it's looking for it in the database directory (the use of "Field1" etc. below is for demo purposes only and you should have your real table field names in there):
$sqlLoad = "LOAD DATA LOCAL INFILE '".$csvfile."' INTO TABLE my_table FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (Field1,Field2,Field3,Field4) SET ID =".$id
Lastly, you really need to read through this page in the MySQL manual. It covers many of the issues you're dealing with along with providing examples:
