Example 1 with SystemSessionProperties

use of com.facebook.presto.SystemSessionProperties in project presto by prestodb.

the class TestAnalyzer method testTooManyGroupingElements.

@Test
public void testTooManyGroupingElements() {
    Session session = testSessionBuilder(new SessionPropertyManager(new SystemSessionProperties(new QueryManagerConfig(), new TaskManagerConfig(), new MemoryManagerConfig(), new FeaturesConfig().setMaxGroupingSets(2048), new NodeMemoryConfig(), new WarningCollectorConfig(), new NodeSchedulerConfig(), new NodeSpillConfig(), new TracingConfig()))).build();
    analyze(session, "SELECT a, b, c, d, e, f, g, h, i, j, k, SUM(l)" + "FROM (VALUES (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12))\n" + "t (a, b, c, d, e, f, g, h, i, j, k, l)\n" + "GROUP BY CUBE (a, b, c, d, e, f), CUBE (g, h, i, j, k)");
    assertFails(session, TOO_MANY_GROUPING_SETS, "line 3:10: GROUP BY has 4096 grouping sets but can contain at most 2048", "SELECT a, b, c, d, e, f, g, h, i, j, k, l, SUM(m)" + "FROM (VALUES (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13))\n" + "t (a, b, c, d, e, f, g, h, i, j, k, l, m)\n" + "GROUP BY CUBE (a, b, c, d, e, f), CUBE (g, h, i, j, k, l)");
    assertFails(session, TOO_MANY_GROUPING_SETS, format("line 3:10: GROUP BY has more than %s grouping sets but can contain at most 2048", Integer.MAX_VALUE), "SELECT a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, " + "q, r, s, t, u, v, x, w, y, z, aa, ab, ac, ad, ae, SUM(af)" + "FROM (VALUES (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, " + "17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32))\n" + "t (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, " + "q, r, s, t, u, v, x, w, y, z, aa, ab, ac, ad, ae, af)\n" + "GROUP BY CUBE (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, " + "q, r, s, t, u, v, x, w, y, z, aa, ab, ac, ad, ae)");
}

Example 2 with SystemSessionProperties

use of com.facebook.presto.SystemSessionProperties in project presto by prestodb.

the class TestAnalyzer method testWindowOrderByAnalysis.

@Test

    // Now test for error when the session param is set to disallow this.
