The following set of simple examples shows the valid use of UDT expressions in a SELECT statement:

     SELECT euro_column
     FROM t1;

     SELECT euro_column.roundup(0)
     FROM t1;

     SELECT address_column.street(), address_column.zip()
     FROM t2;

     SELECT t.address_column.ALL
     FROM t2 AS t;

     SELECT address_column
     FROM t2
     WHERE address_column.zip() = '92127';
    
     SELECT *
     FROM t3
     WHERE circle_column = NEW circle(1.34, 4.56, 10.3);

     SELECT circle_column.area()
     FROM t3;

The following example shows the need to cast the distinct UDT column named myDollar to compare it with a DECIMAL value.

     SELECT *
     FROM t4
     WHERE myDollar < (CAST 3.20 AS DollarUDT);
