prepend `use $MYSQL_DATABASE;` to .sql files

[srtlg]

Hello, I am just wondering, how you use this feature. In my understanding those .sql files are scripts created by mysqldump for one database, that will become $MYSQL_DATABASE of the container. In my adaption, I found the following changes useful:

        for f in /docker-entrypoint-initdb.d/*; do
                case "$f" in
-                       *.sql)    echo "$0: running $f"; /usr/bin/mysqld --user=root --bootstrap --verbose=0 --skip-name-resolve --skip-networking=0 < "$f"; echo ;;
-                       *.sql.gz) echo "$0: running $f"; gunzip -c "$f" | /usr/bin/mysqld --user=root --bootstrap --verbose=0 --skip-name-resolve --skip-networking=0 < "$f"; echo ;;
+                       *.sql)
+                               echo "$0: running $f"
+                               { echo "use \`$MYSQL_DATABASE\`;" ; cat "$f" ; } \
+                               | /usr/bin/mysqld --user=root --bootstrap --verbose=0 --skip-name-resolve --skip-networking=0
+                               echo ;;
+                       *.sql.gz)
+                               echo "$0: running $f"
+                               { echo "use \`$MYSQL_DATABASE\`;" ; gunzip -c "$f" ; } \
+                               | /usr/bin/mysqld --user=root --bootstrap --verbose=0 --skip-name-resolve --skip-networking=0
+                               echo ;;
                        *)        echo "$0: ignoring or entrypoint initdb empty $f" ;;
                esac
                echo

If you could tell us more about what this does then i will merge if it's useful.

It lets you import the output of mysqldump Database directly into the container as it will not include the database name.
