Example 41 with QueryMetadataInterface

use of org.teiid.query.metadata.QueryMetadataInterface in project teiid by teiid.

the class TestOptimizer method testAmbiguousAliasFunctionInSubQuerySource.

/**
 * Test the query optimizer's ability to properly plan and optimize a query
 * that uses ambiguous alias names in the top level query and its sub-query
 * and uses columns belonging to the alias as a parameter to a function.
 * <p>
 * For example, <code>SELECT CONVERT(A.e2, biginteger) AS e2 FROM (SELECT
 * CONVERT(e2, long) AS e2 FROM pm1.g1 AS A) AS A</code>
 * <p>
 * The test is to ensure that A.e2 from the top level is not confused with
 * e2 in the second level.
 * <p>
 * Related Defects: JBEDSP-1137
