Hello fellow monks,

I'm trying to append some text to a column in a database table, in a way that's straightforward and atomic. Basically I want to say: 

  UPDATE table SET item = append(item,'new text\r\n')

[download]
The database is currently Microsoft SQL Server, and the data type of this column is Text (basically a BLOB of text, as compared to a string). Ideally I'd like something portable, but I'll take what I can get.

We're writing into a database used by a proprietary application, so I can't make any changes to the table structure.

Currently I'm reading the column, appending the text, then writing it back out. This works, but is ugly, and prone to race conditions.

Any suggestions?
