Can somebody help me to appreciate the difference between returning a setof record with cursor or with for _row in select ... as in http://people.planetpostgresql.org/xzilla/index.php?/archives/149-out-parameter-sql-plpgsql-examples.html Once I use and define cursors read only, no scroll, insensitive (that should give enough information to use the cursor as a standard query) I see there is an interesting advantage over for _row in select: you don't have to specify the output type. Is there any hidden penalty using cursor vs. for _row in select? What's the meaning of: "which can be used to retrieve a small number of rows at a time out of a larger query". -- Ivan Sergio Borgonovo http://www.webthatworks.it ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
