I am getting null with below syntax

 public static final Field<String> COLUMN=field(name("myid"), SQLDataType.VARCHAR)
 public static final String TABLE_NAME = "mytable";
 public static final Table<?> TABLE_WITH_SCHEMA = table("common",TABLE_NAME);
 public static final Field<String> MY_FIELD=TABLE_WITH_SCHEMA.field(COLUMN);

What am I doing incorrectly here? When I run the code MY_FIELD comes out as null
