Subject SQLTemplate for not object queries and NullPointerException
Date Mon, 07 Dec 2009 10:52:15 GMT
Today I tried to use SQLTemplate for not object query (expecting to
get list of DataRows).

Here is what I did:

    public void testSQLTemplateForDataMapWithInsert() {
        DataMap testDataMap = context.getEntityResolver().getDataMap("testmap");
        String sql = "INSERT INTO ARTIST VALUES (15, 'Surikov', null)";
        SQLTemplate q1 = new SQLTemplate(testDataMap, sql);
        context.performNonSelectingQuery(q1);

        SQLTemplate q2 = new SQLTemplate(testDataMap, "SELECT * FROM ARTIST");
        List<DataRow> result = context.performQuery(q2);
        assertEquals(1, result.size());
    }

I got :

Going to create JIRA issue for it...
