Examples of org.teiid.query.sql.lang.Command

org.teiid.query.sql.lang.Command
A Command is an interface for all the language objects that are at the root of a language object tree representing a SQL statement. For instance, a Query command represents a SQL select query, an Update command represents a SQL update statement, etc.

        Command command = TestXMLProcessor.helpGetCommand(sql, md);
        return preparePlan(command, md, TestOptimizer.getGenericFinder(), null);
    }


    private void helpPlanException(String sql, QueryMetadataInterface md) throws QueryMetadataException, TeiidComponentException, TeiidProcessingException {
        Command command = TestXMLProcessor.helpGetCommand(sql, md);


        try {
            preparePlan(command, md, TestOptimizer.getGenericFinder(), null);
            fail("Expected exception for planning " + sql); //$NON-NLS-1$
