How do I dump MySQL file without Foreign Keys via command line?

Question

I need to export a large database without foreign keys. What is the command to do this?

This is what I tried but I know this is incorrect.

mysqldump         


        

Answer 1

This is ugly, but I ended up just modifying the schema file to remove the foreign keys.

Dump schema only, no foreign keys

mysqldump -uuser -ppassword --no-data dbname | sed '$!N;s/^\(\s*[^C].*\),\n\s*CONSTRAINT.*FOREIGN KEY.*$/\1/;P;D' | grep -v 'FOREIGN KEY' > dbname_schema_no_fk.sql

sed finds lines that precede foreign key constraint declarations and replaces those lines with themselves, minus the trailing comma. grep excludes the foreign key constraints.

Dump data only, no table creation

mysqldump -uuser -ppassword --no-create-info dbname > dbname_data.sql

Load schema first, then data

$ mysql -uuser -ppassword
> create database foo
> use foo
> source dbname_schema_no_fk.sql
> source dbname_data.sql

Tested with mysqldump Ver 10.13 Distrib 5.6.32-78.1, for Linux (x86_64).
