Re: Re: DBI - retrieving a specific row

Ahhh...LIMIT sound like just what I need.

Makes sense that it wouldn't be in the DBI book...need to get me the SQL book.

Thanx for the suggestions all.

I would recommend you getting SQL In A Nutshell (O'Reilly) - I've only had it 3 months and it's alreeady quite thumbed and bent. Page 149 gives SELECT...LIMIT as a MySQL specific and PostgreSQL specific functions, the syntax is: MySQL: `SELECT * FROM table_name LIMIT (starting_row-1),number_of_rows` PostgreSQL: `SELECT * FROM table_name LIMIT number_of_rows,(starting_row-1)` Don't get the two different parameter orders mixed up! If you aren't using either of these databases (have a look at this comparision table between them if need be), use might be able to use stored procedures to do the job. For a database-independent way, you'll be best having a function within your script in which you loop round to get the data you require.	[reply] [d/l] [select]
