Exporting a MySQL table into a CSV file

Question

I have a MySQL table which has to be taken out as a CSV file. The query I used is

SELECT "ID","NAME","SALARY","SAL1","SAL2","SAL3","SAL4","SAL5","SAL6","SAL7","SAL8","SAL9","SAL10","SAL11","SAL12","SAL13","SAL14","SAL15","SAL16","SAL17","SAL18","SAL19","SAL20","SAL21","SAL22","SAL23","SAL24","SAL25","SAL26" UNION ALL SELECT * FROM addstock25 INTO OUTFILE "E:\\JOSE DATA\\addstock7.csv" FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'; 

This query works, but what if I have 200 column names? Is there a way to do it without manually typing it?

Answer 1

This command almost gives you what you want, and it even works with a remote server. The only caveat is that it generates a TSV file (fields are separated by a tab).

mysql mydb -e "select * from mytable" -B > mytable.tsv  

But you could convert it to CSV using sed, as suggested in this answer:

mysql mydb -e "select * from mytable" -B | sed "s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g" > mytable.csv 

Answer 2

I'm not seeing why you can't do

SELECT * FROM addstock25 INTO OUTFILE "E:\\JOSE DATA\\addstock7.csv" FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
