Export a MySQL table

For reproducing issues or for backing up data from production it can be needed to get an export of a MySQL table. UI tools often fail to export or import large tables. The mysqldump command turned out to work well.

Dump a table in a SQL file

mysqldump -h [host] --single-transaction --set-gtid-purged=OFF -u adrian_read -p [db] [table] > 20200707-[table.sql

Tips:

  • Use a read replica when possible
  • --single-transaction is important to not lock tables
