retrieving 'teaser' from table

[jnxx]

I'm writing a cms where i just want to retrieve a few lines of words from a article posted in a mysql table, sort of like a teaser.

Does any one know how this can be done? OR perhaps point me in the right direction?
Thanks

something like:

select substring(your_field,0,300) will return the first 300 characters of the given field.
