How to Export a MySQL Table from Amazon RDS to CSV Without a Local Server?

Exporting a Table from Amazon RDS into a CSV File: Overcoming the Local Server Issue

Exporting an entire table from a MySQL database running on Amazon RDS into CSV format presents a challenge due to the lack of a dedicated file server for Amazon RDS. Users who attempt to export using the SELECT ... INTO OUTFILE query may encounter an error.

One solution is to utilize the MySQL command line client and pipe the output of the select query to reformat the data as CSV. The following command demonstrates this approach:

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

Alternatively, if the field names are known upfront, a simpler approach can be employed:

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

These methods provide a means to export data from an Amazon RDS database into a local CSV file, bypassing the need for a dedicated file server.
