You need v6.4.2-feature-patch which implement LIMIT option: LIMIT This is a new option to the SELECT statement, telling the database that only some of the rows selected should be returned in the result set. The added syntax of the LIMIT option is: SELECT ... [LIMIT {ALL | lim} [, off]]; or SELECT ... [LIMIT {ALL | lim}] [OFFSET off]; where lim is a positive integer value greater than zero and off is an integer value greater or equal to zero. Both values can be specified as Parameters when using the server programming interface (SPI). In this case, a zero value given in the argument for the lim parameter means ALL. You can find it in patches directory Regards, Oleg On Wed, 10 Feb 1999, Frank Morton wrote: > Date: Wed, 10 Feb 1999 20:36:57 -0500 > From: Frank Morton <fmorton@base2inc.com> > To: pgsql-sql@postgreSQL.org > Subject: [SQL] setting select limit? > > If a select is going to match 1000 records, but I only want to > select the first 25, I thought I could: > > select * from table limit 25; > > But I guess I can't.
