MySQL Select INTO csv file separator working incorrectly - mysql

I am trying to export some data to csv but facing some issue with the "," delemeter.
I am running the below query:
SELECT c.NAME
FROM company c
WHERE COMPANY_ID = 1
INTO OUTFILE 'E:\\ab.csv' FIELDS OPTIONALLY ENCLOSED BY '' TERMINATED BY ',' ESCAPED BY '' LINES TERMINATED BY '\n';
If my name does not contain any "," then the csv is correctly populated but if my "name" field contains "," then data is split into two rows.
For ex:
c.Name = "Google INC" -> Works fine
c.Name = "Google,INC" -> it creates csv with two different column "Google" and "INC".
Kindly suggest what should I do.


Based on the link at the comment you can try something like this
SELECT c.NAME
FROM company c
WHERE COMPANY_ID = 1
INTO OUTFILE 'E:\\ab.csv' FIELDS OPTIONALLY ENCLOSED BY '' TERMINATED BY '",' ESCAPED BY '' LINES TERMINATED BY '\n';
Marking ", instead ,

Error importing csv dates into a mysql server

The following code doesn't work on the part of importing dates and i cant figure why. Dates in the csv are like DD/MM/YYYY and the error is it imports all the data but leaves null every date. Also error says:
ER_UNKNOWN_SYSTEM_VARIABLE: Unknown system variable 'FECHA_POSICION'
Lines in the csv file look like:
EDC00001,66600/7089855,21/01/2021,21/01/2021,"DEPOSIT Deposit",4000,4000
EDC00002,66600/7089855,29/01/2021,29/01/2021,CFDs,"-9,94","3990,06"
USE DATA_BASE;
CREATE TABLE ESTADO_DE_CUENTA (
ID_OPERACION VARCHAR(20) NOT NULL PRIMARY KEY,
ID_CUENTA VARCHAR(20),
FECHA_POSICION DATE,
FECHA_VALOR DATE,
CONCEPTO VARCHAR(100),
IMPORTE FLOAT(12, 2),
SALDO_EN_EFECTIVO FLOAT(12, 2)
);
LOAD DATA LOCAL INFILE 'PATH.csv' INTO TABLE ESTADO_DE_CUENTA2
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(ID_OPERACION, ID_CUENTA, #FECHA_POSICION, #FECHA_VALOR, CONCEPTO, IMPORTE,
SALDO_EN_EFECTIVO)
SET FECHA_POSICION = STR_TO_DATE(#FECHA_POSICION, '%d/%m/%Y')
SET FECHA_VALOR = STR_TO_DATE(#FECHA_VALOR, '%d/%m/%Y')

You can call SEt only once and all columsn have to be separated by comma
Like
USE DATA_BASE;
LOAD DATA LOCAL INFILE 'PATH.csv' INTO TABLE ESTADO_DE_CUENTA2
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(ID_OPERACION, ID_CUENTA, #FECHA_POSICION, #FECHA_VALOR, CONCEPTO, IMPORTE,
SALDO_EN_EFECTIVO)
SET `FECHA_POSICION` = STR_TO_DATE(#FECHA_POSICION, '%d/%m/%Y') , `FECHA_VALOR` = STR_TO_DATE(#FECHA_VALOR, '%d/%m/%Y')

How to use a variable value in a query

As shown in the code below I want to export my tables to the location in 'secure_file_priv', as it is I just manually copy and paste it but I'd like to be able to just use it's value.
USE Library;
show VARIABLES LIKE 'secure_file_priv';
set mylocation := (VARIABLES LIKE 'secure_file_priv');
SELECT 'Id', 'Name', 'Birthplace', 'Birthday', 'Gender'
UNION ALL
SELECT Id, Name, Birthplace, Birthday, Gender
FROM Author
INTO OUTFILE '/var/lib/mysql-files/author.csv'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY ''
LINES TERMINATED BY '\n';
Instead of manually writing '/var/lib/mysql-files/author.csv' I'd like to be able to use the 'secure_file_priv' variable's value.

SET #mylocation = (SELECT ##secure_file_priv);
SELECT 'Id', 'Name', 'Birthplace', 'Birthday', 'Gender'
UNION ALL
SELECT Id, Name, Birthplace, Birthday, Gender
FROM Author
INTO OUTFILE #mylocation
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY ''
LINES TERMINATED BY '\n';

escape sql keywords a csv file when inserting in mysql

I have a csv file which contains a lot of sql keywords. How do i escape the keywords?
sample row from the csv file:
F Aabha Hanjura 115 O/o District Fire Officer Chittor Dist . Chittoor AP 500032 500032 Chittoor AP 9963736976 Ap_Airlt_Pst ANDHRA PRADESH AIRTEL
This is what my import statement looks like:
LOAD DATA INFILE "/home/kannel/2.csv" INTO TABLE number_data COLUMNS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '"' LINES TERMINATED BY '\n';

Mysql convert 'CYYMM' to 'YYMM'

Suck with the following:
$loaddata = "LOAD DATA INFILE 'filename.csv'
INTO TABLE tb1
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\\r\\n'
IGNORE 1 LINES
(
Entity,
HK,
#Period,
)
SET Period = STR_TO_DATE(#Period,'%C%YY%MM')
";
which gives me and sql syntax error near
) SET Period = STR_TO_DATE(#Period,'%C%YY%MM')
Period is a DATE variable. for the period Oct-13 the cvs will show 11310.
tks in advance!

You have a superfluous comma after #Period:
$loaddata = "LOAD DATA INFILE 'filename.csv'
INTO TABLE tb1
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\\r\\n'
IGNORE 1 LINES
(
Entity,
HK,
#Period -- , removed here
)
SET Period = STR_TO_DATE(#Period,'%C%YY%MM')
";
However, your date format string is almost certainly incorrect. %C, %YY and %MM are invalid specifiers. See DATE_FORMAT().

How to SELECT INTO OUTFILE with header labels enclosed by quotes but not body fields?

I do not believe this question is a duplicate.
I want rows in the body to be "OPTIONALLY ENCLOSED BY" double quotes. Numerical values should not be enclosed. That's easy to do without a header. But when you include a header using UNION, MySQL now treats every column as a string type and encloses all the values in quotes.
You can add a header to SELECT INTO OUTFILE like this:
SELECT "id", "numerical_values", "string_values" #header section of csv
UNION ALL
SELECT `id`, `numerical_values`, `string_values` #body section of csv
INTO OUTFILE "/tmp/values.csv"
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY "\n"
FROM `values_table`
Again, if I omit the header, only string_values will be enclosed by quotes.
With the header, all columns are seen as string columns and will be enclosed.
I tried this:
SELECT '"', "id", ',"', "numerical_values", ',"', "string_values", '"'
#added quotes/commas to header
UNION ALL
SELECT `id`, ',', `numerical_values`, ',"', `string_values`, '"'
#added commas, and add quotes around string_values
INTO OUTFILE "/tmp/values.csv"
FIELDS TERMINATED BY "" ENCLOSED BY '' #empty values for fields terminated and enclosed
# empty because manually selected in query
LINES TERMINATED BY "\n"
FROM `values_table`
I thought that would work, but I ended up with what looks like a bunch of extra whitespace. This is from an file I just created with the 2nd method. The header row ends at "string7". The 1st line of data ends after "207". I just put part of the 3rd line.
" num1"," string1"," num2"," string2"," num3"," string3"," num4"," string4"," num5"," string5"," num6"," string6"," string7""
33.95 ," 1023 ", 7.50 ," 207-1023 ", 26.95 ,"2 1023 ",23.00 ,"3Wx4Hx4D ",19.00 ,"1023 ", 0.00 ,"UPC: 123456789012 "," 207 "
40.95 ," 1058 ", 9.00 ,

SELECT '"id"', '"numerical_values"', '"string_values"'
UNION ALL
SELECT id, numerical_values, CONCAT('"', REPLACE(string_values, '"', '""'), '"')
INTO OUTFILE '/tmp/values.csv'
FIELDS TERMINATED BY ',' ENCLOSED BY '' ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM values_table
