Here’s how to restore one or more tables from a full database archive. It assumes you used mysqldump to save the database and stored it in a gz file. First create the file extract-table.pl:
#!/usr/bin/perl -wn
# extract-table.pl
BEGIN { $table = shift @ARGV }
print if /^create table $table\b/io .. /^create table (?!$table)\b/io;
Then do the following to restore the table:
zcat /path/mysqldump.date.gz | extract-table Mytable> ~/Mytable.dump
mysql mydatabase -e "drop table Mytable"
mysql mydatabase
