the class ExpressionTypeManagerTest method shouldEvaluateTypeForStructDereferenceInArray.

@Test

    final Expression expression = new DereferenceExpression(Optional.empty(), new SubscriptExpression(TestExpressions.COL0, new IntegerLiteral(1)), "IN0");
    // When:
    final SqlType result = expressionTypeManager.getExpressionSqlType(expression);
    // Then:
