This class is a MySQL database access wrapper. It can:

- Connect to a MySQL server
- Execute SQL queries and retrieve single value results or return result rows into arrays
- Return the last inserted table row identifier, the number of result rows and the number of affected rows
- Count the number of executed queries
- Lock and unlock tables
- Escape text literal values or like patterns
- Retrieve database access errors

This routine will get an image stored in a SQL database (IBM Informix shown here) as a BLOB and return it to the screen.

To place this on an HTML page simply add

I have an MD5 hashed version as well, but can't share that...(So you can have encrypted id's passed)

Have fun,

This is a quick and dirty function for preventing SQL Injection, the function is designed to clean any variable that will be concatenated into an SQL query. Apostrophes and Double-Quotes are changed to entities in order to ensure that encoding does not become an issue when the content is pulled back into a page. I'm looking for criticism here, I want to know if this is secure or not.

Anti-QSL Injection. I'm sure it could be better, so any improvements are welcome.

This is a little script I wrote that copies your database through a cfquery statement

This is an example of how to shrink a database with simple query.

Some usefull snippets for SQL Server.

I actually like SQL. So, things like Hibernate with it's own query language don't quite fit my style. But, I don't want to code the same catch SQLException conn.close over and over either. So, I came up with this.

The idea is you extend SQLCommand (usually anonymously) override getSql(), and call execute() to get a list of whatever objects you are selecting - all the cleanup stuff is taken care of. It also handles nullable attributes more intuitively using ResultSetWrapper and PreparedStatementWrapper so that in your overridden getRow(ResultSetWrapper rs) method, you can call getInt on a nullable column and have it return null - what a concept! Also I like java.util.Date for my dates, so the wrappers convert to/from java.sql.Timestamp.

Right now I've only bothered with some basic types - it should be pretty clear how to add more if you need em.

See what ya'll think.

Oh, it uses JDK 1.5 Generics, but stripping that away would be pretty easy if you wanted 1.2 compliance.
