... without destroying the database.
You can do it all in the shell:
- Create a SQL script from the database to drop all the tables
- Execute the SQL script against the database
mysql -u[pwd] -p[user] [dbname] -s -e 'show tables' | sed -e 's/^/drop table /' -e 's/$/;/' > dropalltables.sql
mysql -u[pwd] -p[user] [dbname] < dropalltables.sql
A quick and dirty way of stripping duplicate records out of a MySQL table!, if your table has no indexes or constraints:
Assuming the name of the offending table is customers:
CREATE TABLE customer_dedupe AS SELECT DISTINCT * FROM customers;
RENAME TABLE customers TO customers_dupe;
RENAME TABLE customers_dedupe TO customers;
But what if your original table had indexes?
The task of matching strings between heterogeneous systems, especially that of matching personal or company names or addresses, is not easy with SQL Server's limited set of built-in string SQL functions. Here is a C# CLR-Assembly (with source code) for SQL Server with some advanced string-handling functions that may help:
LTrim - like Oracle's LTRIM function.
InitCap - like Oracle's INITCAP function
FlattenCharSet - Replace western characters with diacritics with best-choice, non-diacritic characters
StripPunctuationMarks - Remove all punctiation marks from the given string.
Directly Burn DVD's from .avi files
Here is a quick and simple-to-use utility to convert an AVI file to the weird intermediate files and to then write them all to a DVD. It is called avi2dvd and is written in BASH-shell. It is unlikely to run on Windows.
More about it here at https://sourceforge.net/projects/avi2dvd
So, you downloaded a torrent expecting a nice AVI- or MPG-file for instant-action AV entertainment, and all you got was a big .bin file and a funny little .cue file? Here's the Linux-way of how to extract the content from them:
Yet another bespoke file format that unsuccessfully attempts to futher the agenda of vendor lock-in: If you are running Windows, you need to purchase PowerISO from poweriso.com , if you are running X86-based Linux flavour, the same people offer a free program to read and write .daa files. Go figure...
A well-meaning person gives you a .nrg file and you will not invest in a piece of expensive bespoke software to read it. After all, you run free, open-source software and never have and never will pay for software. What to do with this stupid .nrg file?
These utilities are particularly useful for installing Perl on your Windows PC. Download Perl for Windows from http://www.activeperl.com.
