How Can I Export Data from Amazon RDS to CSV Format?

Exporting Data from Amazon RDS to CSV Format

When working with an Amazon RDS MySQL database, you may encounter challenges when attempting to export data to CSV via the traditional SELECT ... INTO OUTFILE query. This is because Amazon RDS lacks a dedicated file server, resulting in an error message.

Fortunately, there are alternative solutions available:

Piping the Output to Reformat as CSV

One approach is to select the data in the MySQL command line client and pipe the output to reformat it as CSV:

mysql -u username -p --database=dbname --host=rdshostname --port=rdsport --batch
  -e "select * from yourtable"
  | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' > yourlocalfilename

Specifying the Fields Upfront

If you know the fields you need to export beforehand, you can use a simplified approach:

mysql -uroot -ppassword --database=dbtest
  -e "select concat(field1,',',field2,',',field3) FROM tabletest" > tabletest.csv

These methods provide viable alternatives for exporting data from Amazon RDS into CSV format, bypassing the limitations associated with the lack of a dedicated file server.
