Select the column of the attribute you want to change. From the transform menu, select Convert to <type> and the data type transform you want. When you select a Convert to <type> transformation, it is immediately added to the transformation script. There is no configuration, and the change always overwrites the selected attribute.

Unrenameable data sets cannot be renamed unless you first override this attribute through a CHANGE RENAME command. For information about unrenameable data sets, see CHANGE RENAME. If you change the high-level qualifier of a data set, you might need to re-establish its catalog and SMS relationships.

The arguments passed to the circle constructor are used to initialize the data attributes of the newly created circle instance. It is helpful to think of self as a box that contains all the data attributes of the object. Typing the object's name followed by a dot and the data attribute name gives us the data attribute value, for example, radius.

Change data types. Before you follow these steps, remember that changing a data type might truncate (cut off) some or all of the data in a field, and in some cases may remove the data entirely.
