Exporting Data from Amazon RDS MySQL to CSV

Exporting an entire table to CSV format from an Amazon RDS MySQL instance can pose a challenge due to the lack of a dedicated file server. To address this, consider the following solutions:

Using the MySQL Command Line Client

1. Connect to your RDS MySQL instance using the mysql command:

   mysql -u username -p --database=dbname --host=rdshostname --port=rdsport --batch

   Copy after login

2. Select the data from the desired table and pipe the output to reformat it as CSV:

     -e "select * from yourtable" \
     | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' > yourlocalfilename

   Copy after login

Using a Predefined Field List

If you know the fields upfront, you can use a simpler approach:

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

This method allows you to customize the field order and excludes unsupported characters like line breaks and tabs. By following these steps, you can successfully export a table from Amazon RDS MySQL to a CSV file.
