Automating MySQL Table Dumps into Separate Files
Mysqldump offers a convenient way to dump MySQL tables into individual files. However, knowing the table names beforehand is a limitation. To address this, there are alternative approaches to automatically dump each table.
Script-Based Approach:
By leveraging script-fu, you can query the database to retrieve all table names and create a script that performs the dumps. Here are some scripting languages capable of accessing MySQL databases:
Self-Contained Bash Script:
The provided Bash script streamlines the process further, eliminating the need for additional scripting knowledge:
<code class="bash">#!/bin/bash # dump-tables-mysql.sh [ $# -lt 3 ] && echo "Usage: <DB_HOST> <DB_USER> <DB_NAME> [<DIR>]" && exit 1 DB_host= DB_user= DB= DIR= [ -n "$DIR" ] || DIR=. test -d $DIR || mkdir -p $DIR read -sp "DB password: " DB_pass echo echo "Dumping tables into separate SQL command files for database '$DB' into dir=$DIR" tbl_count=0 for t in $(mysql -NBA -h $DB_host -u $DB_user -p$DB_pass -D $DB -e 'show tables') do echo "DUMPING TABLE: $DB.$t" mysqldump -h $DB_host -u $DB_user -p$DB_pass $DB $t | gzip > $DIR/$DB.$t.sql.gz tbl_count=$(( tbl_count + 1 )) done echo "$tbl_count tables dumped from database '$DB' into dir=$DIR"</code>
This script prompts for the database password, dumps each table's data into a separate compressed SQL file, and stores them in a specified directory. It handles all necessary steps, from retrieving table names to creating the dump files.
