James Taylor resolved PHOENIX-2277.
-----------------------------------
Resolution: Duplicate
Fix Version/s: (was: 4.8.0)
This is a duplicate of PHOENIX-1499 and a known limitation [1]:
bq. An INDEX over a VIEW is only maintained if the updates are made through the
VIEW. Updates made through the underlying TABLE or the parent VIEW will not be
reflected in the index.

The following test passes fine:
{code}
@Test
public void testIndexesOnTenantViews() throws Exception {
String baseTable = "testIndexesOnTenantViews".toUpperCase();
String tenantView = "tenantView".toUpperCase();
String tenantViewIdx = "tenantView_idx".toUpperCase();
try (Connection conn = DriverManager.getConnection(getUrl())) {
conn.createStatement().execute("CREATE TABLE " + baseTable + "
(TENANT_ID CHAR(15) NOT NULL, PK2 DATE NOT NULL, PK3 INTEGER NOT NULL, KV1
VARCHAR, KV2 VARCHAR, KV3 CHAR(15) CONSTRAINT PK PRIMARY KEY(TENANT_ID, PK2,
PK3)) MULTI_TENANT = true");
}
String tenantId = "tenant1tenant12";
try (Connection conn =
DriverManager.getConnection(getTenantUrl(tenantId))) {
conn.createStatement().execute("CREATE VIEW " + tenantView + " AS
SELECT * FROM " + baseTable);
conn.createStatement().execute("CREATE INDEX " + tenantViewIdx + "
ON " + tenantView + " (PK2, KV2) INCLUDE (KV1)");
}
Date upsertedDate = new Date(5);
try (Connection conn =
DriverManager.getConnection(getTenantUrl(tenantId))) {
PreparedStatement stmt = conn.prepareStatement("UPSERT INTO " +
tenantView + " (PK2, PK3, KV1, KV2) VALUES (?, ?, ?, ?)");
stmt.setDate(1, upsertedDate);
stmt.setInt(2, 3);
stmt.setString(3, "KV1");
stmt.setString(4, "KV2");
stmt.executeUpdate();
conn.commit();
}
// Verify that data can be queried using tenant view and tenant view
index
try (Connection tenantConn =
DriverManager.getConnection(getTenantUrl(tenantId))) {
// Query the tenant view
PreparedStatement stmt = tenantConn.prepareStatement("SELECT KV2
FROM " + tenantView + " WHERE PK2 = ? AND PK3 = ?");
stmt.setDate(1, upsertedDate);
stmt.setInt(2, 3);
ResultSet rs = stmt.executeQuery();
assertTrue(rs.next());
assertEquals("KV2", rs.getString("KV2"));
assertFalse(rs.next());
// Query using the index on the tenantView
stmt = tenantConn.prepareStatement("SELECT KV1 FROM " + tenantView
+ " WHERE PK2 = ? AND KV2 = ?");
stmt.setDate(1, upsertedDate);
stmt.setString(2, "KV2");
rs = stmt.executeQuery();
QueryPlan plan = stmt.unwrap(PhoenixStatement.class).getQueryPlan();
assertTrue(plan.getTableRef().getTable().getName().getString().equals(tenantViewIdx));
assertTrue(rs.next());
assertEquals("KV1", rs.getString("KV1"));
assertFalse(rs.next());
}
}
