limiting amount of returned rows?
limiting amount of returned rows?
am 27.03.2006 17:40:15 von Sonnich
Hi!
How do I limit the amount of returned rows?
Lets say, that I want only the latest 400 rows (of e.g. 4034634 rows) -
is there a parameter for that like rownum in Oracle?
e.g. select * from someplace where rownum < 400 order by sometimefield?

The optional LIMIT clause of queries can do this.
Read about it on this page:
http://dev.mysql.com/doc/refman/5.0/en/select.html
Starting at the bullet item that begins, " The LIMIT clause can be used to
constrain the number of rows returned..."
