with 5m result set you can set fetchsize to any value it has no effect @GrabConfig(systemClassLoader = true) @Grab(group='postgresql', module='postgresql', version='8.3-603.jdbc4') @Grab(group='commons-lang', module='commons-lang', version='2.6') import groovy.sql.Sql import org.apache.commons.lang.math.RandomUtils def sql=Sql.newInstance("jdbc:postgresql://localhost/grails", "postgres", "postgres") sql.setCacheStatements(true) /* sql.withTransaction { for (i in 1..5000000 ) { sql.executeUpdate("insert into public.test (a) values (?)", [RandomUtils.nextLong()]) } } */ def c = sql.getConnection() def s = c.createStatement() s.setFetchSize(100000) def r = s.executeQuery("select * from public.test") def cnt = 0 while (r.next()) { cnt++ } println "${cnt} rows." sql.close()
